Whenever I use google docs, and try to select text, move between headings, format text, or type, my cursor will jump up significantly, either a few lines, or several headings depending on the action being performed. tested in other browsers, only occurs in firefox, and even booting it up in troubleshooting mode does not resolve the issue.

this is the only site where this occurs, so I thought it was an extension, but troubleshooting mode seems to indicate that it's not. Attempting to clear caches and reload the site doesn't work either. Currently using a wireless keyboard and mouse, not on a laptop with a touchpad, so it doesn't seem to be an input issue Like touching a pad indiscriminately. Advice?

Hi,

I'm on Arch Linux and use uinput to create key events. It works reliably for >12months in all applications and under all circumstances except in Firefox where some key events are skipped non-deterministically. My test case is:

in a text field, emit `<ctrl down>a<ctrl up>123456789987654321<left>...<left>` with 9 times `<left>`. Sometimes a 9 is missing and sometimes the cursor is further to the right than expected.

This happens every 8th try or so, which is too frequent to not break the user experience.

What I have tried: - multiple PCs (2 with this issue and 1 without) - Troubleshoot Mode - `window.onkeydown=(e)=>console.log(e)` (events are missing)

Since I've only ever seen repeated characters/keys disappear and never when writing manually, I would guess there is some kind of event cleanup algorithm kicking in. (the events are emitted without any delays)

I would really like to fix this issue because Firefox is my favorite browser. Any idea how to track it down?

After update to 115.2.1, FF crashes at startup for one User, but not the other. FF Safe Mode also crashes (SHIFT key). I tried running the 115.2.1 install on the problem User, but it also crashes right after completion. The second user is handicapped, so I have yet to try to uninstall/reinstall because FF runs on her User and I hate to screw things up so that she is locked out.

• • • JUST NOTED - Chrome also crashes with same NTDLL error (same DLL version number). Did the FF update do something with the NTDLL file?

Firefox opens blank tabs when following link on existing logged in websites, for example Screwfix. Worked previously, suddenly stopped yesterday. Refreshed Firefox, no change. Re-installed Firefox, no change. Site works fine in Chrome and Edge, so not site error, internet error, PC error, or network error. Please help? Thanks, Mark

At some point, I've noticed that certain behaviours expected to occur when pressing the Escape key no longer did. Those behaviours mainly involved triggering some Javascript, including functionality in keyboard-related extensions, such as Tridactyl. Browser-level functionality on the other hand, such as pressing Shift-Escape to open `about:processes`, or pressing Escape to close Search Suggestions when the URL input bar, continue to work as before.

Upon investigation, I found it is specifically the javascript Keydown event that isn't being registered, while the subsequent Keyup event still is. I used https://w3c.github.io/uievents/tools/key-event-viewer.html to test this.

I also found that starting Firefox in Troubleshoot Mode (Safe mode) doesn't resolve the issue. On the other hand, creating a new profile does.

I've looked at the modified settings in `about:config`; there's a lot, but nothing stands out as being related to keyboard input or javascript.

Can someone please help me find what is causing this?

hello. I have a reproducable issue with Firefox. If I use the touch keyboard on Firefox and then exit Firefox without without closing the touch keyboard, when I next start Firefox it only opens with a half view. if I close the touch keyboard first and then exit Firefox it opens as normal in a full screen view. it has nothing to do with either an extension or a theme. is there any way of ensuring that FF opens in full screen view if I forget to close the touch keyboard before exiting the browser? thanks in advance. PS: device is a Surface Pro 7 running Windows 11.

Using Firefox 17.0.1 on MacOS Ventura 13.6 on my 2017 iMac I am unable to connect to the internet while using Private Internet Access (PIA) VPN. All was working normally until I installed MacOS Ventura 13.6 yesterday. The VPN works normally when using Chrome or Safari. I have tried changing my network proxy setting without any luck. The default setting is "Use System Settings", using No Proxy or Auto Detect Proxy doesn't help. I don't see a switch for Enable DNS over HTTPS. All works fine when the VPN is disabled. I tried deleting the VPN a couple of times then reinstalling but that didn't help.

What am I missing here? I have used this VPN for years without any issues & it worked on Firefox until I installed MacOS 13.6...... using 13.5 I had no problems. Any suggestions or thoughts would be appreciated.

Thanks...... Brad

I've noticed this issue happening randomly, some of my toolbar bookmarks listed on the sidebar just up and disappear from view. As if they were never there. But I know they're still saved because when I click to Manage Bookmarks and check them there, they show up fine. The toolbar just randomly hides them for whatever reason, and I can only fix it by closing Firefox and opening it again.

I'm on the current version. I remember accessing about:support and clicking on Verify Integrity while trying troubleshoot some other issue, but don't know if that could've caused it though.

Ever since switching to Windows 11 I've had an issue with Firefox. Any time I copy something in Firefox, be it image, article text, or even a url from the address bar, I cannot paste it anywhere, and my copy and paste stops working. The only way to fix it is to close Firefox, and then run rdpclip.exe as an administrator. I've confirmed the issue only occurs if I try copying from Firefox, as it doesn't happen in Edge.

Does anyone know what might be causing this. It's very frustrating.

[Windows 11 22H2, Firefox 117.0.1 (64-bit)]

i often have a Main and Private window open concurrently. All too often the Private window will close while Windows is locked - Sleep or Hibernate - but the Main window always stays open. The results range from annoying to extremely aggravating.

Other than saving the open tabs as needed = assuming I remember, to reopen every time this occurs.

Why is this occurring, and h9w can I fix it?

Basically as the title says. The only sites this is an exception for is youtube as well as big streaming services but on youtube the video seems like it takes longer to buffer and has a lot more pauses.

I am on Version 117.0.1 which was installed on September 12th for me. I did not notice any issues prior.

I am on a macbook air which is updated to latest software.

I have tried the following:

Running it in troubleshoot mode. It did not fix the issue.

Turning on/off autoplay. It didn't work.

Clearing cookies/cache. Nothing.

Started firefox without a theme. Didn't do anything.

I unchecked "Use hardware acceleration when available." which did nothing.

Sites I have tried watching videos on include:

reddit

pornhub/other porn sites (for testing purposes...)

instagram

Vimeo

Hi! I have two Firefox accounts, one for work and one for personal use. I often have them running on the same computer at once (this does cause them to crash occasionally, but not often enough to be a problem). However, today I tried to log into a website where I regularly do freelance work and received this error code: "Error code: SSL_ERROR_PROTOCOL_VERSION_ALERT"

I would assume something was wrong with the website itself, however when I went to that same site on my other account, it loaded just fine. I've restarted my computer, restarted firefox, deleted cookies and caches and browser history, but still get the same message on my work account. Any idea how to fix this?

Thanks!

Hi, I get the below error message when trying to login to visma.net (for work).

json.parse unexpected character at line 1 column 1 of the JSON data

On this note I have a previous error, loggin in to this site that was fixed by a support member (• accessibility.blockautorefresh = false), but I have the above hurdle left. I can get past it by clicking backspace but thought there might be a better solution - maybe some other setting I can adjust similar to the first fix I got help with.

The web address for this error message shows as: https://api.home.visma.com/home/rest/sso/login

So, here's the story:

My browser crashed while watching a video and writing a particularly lengthy YouTube comment on it. Knowing that I have been able to recover in-progress Reddit comments after a crash from the sessionstore-backups so long as I was on the page at the time of the crash, I know that at least one site saves all in-progress comments to that, and I highly suspect that is where in-progress Wikipedia edits are kept, I (wanting as much data as possible for as good of a recovery chance as possible) immediately copied all my Profile files, totalling more than 1.6 GB, to a non-volatile folder.

As I had done before, I took the most recent sessionstore-backups file (dated to the exact minute of the crash), forced it through the Session History Scrounger to decompress it, and then mass-replaced the document's \ns with proper newlines in Notepad++, which used to make the file more readable.

This time, it didn't. They must have changed the json newline formatting used between at least late April and now. And more importantly, when I searched through the file for keywords I used in the comment, I couldn't find it. Simply, it appears that in-progress YouTube comments aren't stored in that file.

So, where are they stored? Are they in any vaguely human-readable file (or file that can with some ease be converted into something vaguely human-readable)? Can I somehow revive a "zombie session" using just archived Profile folder data to copy it out of? Or should I just give up and rewrite the comment from scratch?

NOTE 1: This is adapted from a previous post made with an associated account on Reddit. As I fear using Firefox until I get this problem resolved due to the possible loss in ability to recover other data if I do so, I figure that giving the problem more attention here would be beneficial in resolving it more quickly.

NOTE 2: Also, to clarify, I don't need to restore the session and have the comment re-appear; I'd be fine with locating it in a text editor or similar program so I could copy it back into the submission box once the session is restored.

I have the same issue as stated in https://support.mozilla.org/en-US/questions/1390122?page=3

How does it come that it is still present in 117? Why is there no official guide or warning about this issue? I am forced to use Portable 101 where there are no such bugs. The solution in the thread is unclear and points to Microsoft, which is ridiculous. The question is how to solve that Mozilla's bug?

The right pane on google drive is not loading on firefox. It says "Couldn't load, Try again". Dev tools show the error "NS_ERROR_INTERCEPTION_FAILED".

If i clean the data and cookies for the website it starts working but not for long. Last time i did it i lasted like 5 minutes. Turning off all the extensions doesn't help.

I'm logged in on several google accounts, don't know if that matters.

As per subject. After i close FF - and it is no longer showing as an app in Task manager. When i try to restart it, it says it's still running and i have to ask it to close FF before it will open it again. AFAICS It happens randomly.

It may be relevant that when using CCleaner, it often (randomly) hangs when cleaning FF internet cache and says FF needs to be closed when it is already closed and does not appear in task manager. If i ask CCleaner to close FF, the application hangs.

Less likely perhaps to be relevant: i got a rogue change of Favicon on one site. I eventually deleted the relevant file hoping the Favicons would repopulate. Most have, but many haven't including hotmail and protonmail sites.

There seem to be many causes/solutions to FF hanging but i thought these specific circumstances might make it easier to suggest what the problem is exactly and how to fix it.

Thanks.

Please HELP -- I can no longer use Thunderbird or Firefox to access my emails at the University of Vermon (UVM). For over about 2 months after the Univ. of Vermont went to a new email system, I can no longer use Thunderbird or Firefox to get my emails. I get an error message when I enter my NetID and password at

https://adfs.uvm.edu/adfs/ls/        or   https://webauth.uvm.edu/webauth/login?RT=ZQy0vGaH7hXE%20BIXYqeBrf8AW817EA2ZEgHD5NywxXEKicTPOPs4jvfqMM1T9WiTY2sJpxG3mUbgwZ%20oW%20wliuVFGhQ9vFzD12bdJTM4FXUcyuQi%2Fo6%2F7zhAZ2ez%20uYFe0ds5tUDcQVhf%20jzr0i1MSDJlBZ%2Fqp6YXfHB3zHgNlGsV3eb0QbClx9lt6AtFahFGLLykYMswanRENJNTkXaRe%2FHypzNXIcppX22Ota7hGSkkVx7g2ChYFxgPaK2W1xDgpAMNS8O1F6HfjOao96aRrWOo4Ltqb0jfSHYpYRjantewrxjZUHG9yiLS1yI6C3YR06tb84wb6%2Fs4lUrDAJadCfJz3GJP8qkOJyrSmjI0%20%20WMo8U;ST=ZQyp228WbdkSw1QKFNvUgJvqzpLVg0x5cQFiBGwk3jd9QLdWxEo7Wg90eK09yvoz1npFIMkViO0k3J3d8%20prFPvXmkpA99rhjvwO9qDqHU8ZvduICJM8IjgoqGCTfAUUjg3k280qveVCzlkbyJtJ4rga3RFnod9IrEbgHy2dgeBcXuop;test_cookie=1

Many bugs and crashes with Firefox

1. 1 Not able to install an automatic update, via the Menu Help --> About Firefox (or Thunderbird). This bug / problems sits already inside the earlier versions of Firefox and Thunderbird.

• A No new version is shown.
• B Firefox (or Thunderbird) tries to download / install this update, bug become someway corrupted and also stuck in this process.
• C Firefox (or Thunderbird) says to apply the update you must restart the program. After Firefox (or Thunderbird) was restarted, the program keeps trying installing or downloading this same or another update. I see a spinning circle only, no progress bar. Waiting, trying again later or another restart from Firefox (or Thunderbird) does nothing.

Only way to update Firefox is via https://www.mozilla.org/en-US/firefox/all/#product-desktop-release Which always shows the wrong language. Only way to update Thunderbird is via https://www.thunderbird.net/en-US/thunderbird/all/#product-desktop-release Here, I can click on letter from my language and download the setup package. After this update installation was done, the Help --> About (program name) window show the program is last version. But not seems not always the last version, like version x.x.01 to x.x.02, then tries to install this newer small version and gets stuck in the same loop or corruption.

• D You must use the setup package, because the installer doesn't work, likes to abort the installation and shows error messages about something gone wrong. Installer package is incomplete or damaged, not for current version and Windows.
• E For last newer versions, they seems not working anymore directly. The program can be restarted once or few times before it seems working. Until other bugs appear.
• F Always adding a new and faulty shortcut, but I have already a working shortcut on my Desktop. Icon hasn't logo from Firefox or Thunderbird, but the setup icon.
• G Sometimes you cannot start Firefox or Thunderbird, due the update did something wrong.

Missing file(s) and/or some strange error message after I clicked on the shortcut from the program. Another run from this "update" setup is needed. Remove a or all "Firefox.exe" from the Taskmanager list.

• H Bug that stops add-ones working. This can be happen due the general function / thing for add-ones inside Firefox crashes, become bugged or corrupted. 1 add-one or more add-ones take the others and stop working, become bugged or corrupted. Add-ones will forget things, their work / functions or do it halfway. Has something to do with the installation and/or data from add-ones. They seems to not having support or do anything about their problems.

1. 2 Random many crashes without any useful (error) messages, can be with closing the program itself.

Already from earlier versions of Firefox. And also Thunderbird too. This bug seems to sit deep inside the programs. I should be to use Firefox, Thunderbird, Notepad together, with having a some folders open. Switching between them can be annoying slow. Takes longer time be before responding. I'm seeing empty white or black windows. Only last selected section is visible, has the text and smaller pictures. I can have Firefox and Thunderbird left open for hours and later finding one or both programs are closed by itself. No reason, no permission given to do that. Add a new tab or click on a current site, there is no (fast) respond. Same for buttons, filters and filling in forms on a site. One program can pull the other program in closing to when the one is crashing. Also Windows will show several error messages about programs are using to much memory and must be closed. If this has programs listed, then Firefox seems to appear most here of the programs I'm using.

Updating doesn't fix anything Using the safe mode and new profiles are no long time solutions, every time anything is gone or nog working better.

It seems you must have 2 profiles running at same time when you want read something and not switching back between every minute or so. If 1 is near crashing, you have still the other one running.

1. 3 Why I'm seeing 20x to 72x a Firefox.exe in my Taskmanager? They takes a lot of memory, showing different sizes. I started Firefox once. This is not needed.

1. 4 Some sites seems to not work in Firefox or takes longer time.

Same for responding on clicking, using filters, buttons and sending forms. Clicking on those (annoying) accept (popup) windows. Unable to login or confirm an (security) action like this with a word or number given via e-mail. Might be something for the site. When you need to use Private Browsing for this.

1. 5 Icons from installed add-ones don't appear in main bar, at right side. How to use them? Before they did.

1. 6 Site using third party host sites are slow and mostly don't work. Connection errors.

"Seems fine here, but something with you". Refresh page doesn't fix it. Wait and try again later, how long? Firefox should block these sites.

1. 7 After updating to Firefox version 115.0.2 and continue my last session, there are appear several new bugs.

• A I cannot longer visit sites. Even earlier visited sites don't load. Firefox keeps stuck in loading or receiving site info data. Sites don't appear, just an empty (white) page. Also about:support doesn't work. Strangely, I can visit Google.com but not open any site from there. I tried Private Browsing, so no add-one can do something with this.

I had Firefox running for some hours, these sites are still stuck in "loading" or something else.

• B Right click to open a site or page in a new tab doesn't longer work. Right click menu appears, but action will not be done. Which can be strange at top, missing or changed items.

• C Same to copy line of text or picture, action isn't longer "remembered".

Now, I created again a new profile and again this doesn't fix them. Even more bugs and stranger. Again lost everything, settings, sites, installing dictionaries and add-ones. Stupid.

• C1 I can visit websites, but with some strange things, not always working fine.

That makes it to post my problems here.

• C2 Cannot longer type keywords in the addressbar and after pressing Enter, you should visit Google with search results. Firefox thinks the given keyword is a not existing website.

In Settings (via about:preferences#search), there are no search engines (Google, Wikipedia, ect) in the list, who should be there by default. Also there's no default search engine selected, the list therefor is small and empty.

• C3 Yet visited near 10 sites, who I cannot visit any of the sites with my other long time using profile. Then Firefox crashed by random, white empty window. Windows adds not responding at end of the program's title bar. I could restart Firefox after that, get the "continue after a crash" tab and revisit any of these sites in their opened tabs.

• C4 A site keeps saying cookies are disabled / denied, while minimal are accepted when some of that stupid (popup) windows did show. This means: Some stupid messages don't disappear after clicking "OK", the "X" or close buttons / links. Site might not work fine or on some parts. Something can follow you browsing through the site. Not able to visit that site or part.

• C5 A site keeps saying there is an ad-blocker installed, but there is no add-one like that installed. This means: Stupid messages like these keep appearing; site cannot work fine; you cannot visit the site due some invisible wall or blocking thing. Some can follow you browsing through the site. This is very annoying.

• C6 With one profile I cannot longer open sites who worked before. Keeps loading, shows URL in addressbar and on the tab.

And the about: .... pages. While with a new profile I can visit those sites, but right click menu is bugged.

• Cannot open site or page in new tab. Only on Google based sites are working for unknown reasons, but not YouTube.
• Missing items or I can see more gray things and lines.
• Cannot copy selected text. Stil having old or wrong text.
• Cannot Search with Google, this option is missing.
• Cannot see the source code from the page, due action is not happen.
• On sites that are working you can only read that current content. Can open links in new tabs, but their pages are empty / white, keep loading forever.
• A few sites don't load and still giving a empty page. Loading takes longer then needed. For same site.
• Use Google by typing the keyword in the addressbar doesn't visit Google site, but Firefox thinks the site doesn't exist, is wrong typed. You must go to Google.com and typing the keyword in the textbox here.
• If a site worked first, then later it cannot working longer, keeps stuck in loading and showing a empty white page / tab.
• Login for some sites is not longer possible, email send with security word or number doesn't appear. I can send myself a test e-mail to this e-mail address. Waited the time enough and made a new attempt, still the same.

Windows PC. Firefox version 117.0 x64. Via Help --> About Firefox, because about:support doesn't show the version and build.
