Hail:

System Software: Win11Ent_x64 v22H2 (b: 22621.2283) MFF v18.5.0.0

No matter what I try, my MFF keeps crashing at startup. For some reason, it tries to open 2 pages the windows at the same time, which is illogical. I deleted firstly my: sessionstore.jsonlz4 logins.json to no avail.

Then I tried to open MFF through elevated CMD with the command: C:\Program Files\Mozilla Firefox\firefox.exe -safe-mode Again, 2 windows pop crashing immediately.

I do not understand why all of the sudden, it tries to open 2 different instances at once. This makes no sense. I am out of ideas, having tried many an option found on Google, but which none give me a solution.

If anyone has an idea, I would be quite darn thankful. This MSEdge crap that I need to use now is not quite my thing.

Thank you. Ke'Ylan

right click menu copy not clickable,cant copy but when I hit ctrl + c and copy something first then i can copy within the right menu fine with the same site, and no this is not a site issue chromium works just fine.

Good afternoon. For the last day or so my Firefox has been running slower than normal. It takes longer to load my home page than normal, for one example. Actually it takes a little longer than it had to load most web pages. I tried opening the same pages on Edge to make sure it is not just an internet issue and Edge works fine.

I am also having an issue with settings. When I open settings, privacy, and navigate to saved logins before when the list would automatically populate it now takes almost 12 seconds to load all my logins.

I did try to run the browser in troubleshoot mode and the behavior did not change.

I am running Firefox 118.0.1. Any help would be appreciated. Thanks in advance.

Over the last year I have uninstalled FF removed settings then reinstalled from scratch. Its been over a year now and FF never can pin point where I am at. Today it says I am 1300+ miles from where I am. I really don't want to go back to using Chrome but it appears I will have to as it normally has my exact position. I travel for 6 months of the year and have 3 internet connections shared via an internal WiFi that I use 99% of the time. They are connected via Starlink, GoogleFi (T-Mobile) and AT&T SIMs. I have a SSID with the _nomap suffix and that fixes Chrome but FF NEVER seems to know where I am, no matter how many times I clear the browsing data. I really don't want to go back to Chrome, but I cannot do my work if FF thinks I am somewhere else all the time. Geez, If only there was an addon or extension that would override FF location so I could tell it where I am. I'm in FF Hell. -Bill

This happens at random intervals, mostly when firefox is being left idle.

Since it starts >1000 threads, it easily fills ram and swap, then get killed by OOM killer. Hence no crash reports.

I'll upload a gist with OOM details from dmesg and journalctl, if there is a way to get debug info for this, please let me know.

I have a General Motors account that I can't login to. https://www.gmccanada.ca/en/ownercenter/service They recently changed to multi authentication using Microsoft. I can login to the first step but after I enter the sent password in the second step nothing happens. I have tried basic some trouble shooting like Firefox trouble mode, clearing cache and adding web site to exceptions in settings. GM Help Line told me to use a different browser!!!

I am using Firefox 115.3 on Debian 12.1. I have numerous tasks which require the use of my web browser and have allocated a different virtual desktop for each. This means that my browser session typically has several dozen tabs open in numerous windows at one time. Under normal circumstances, this works just fine (and is a testament to the engineering that has gone into this browser).

My issue is that Firefox renders my machine virtually unusable for a few minutes each time I restart my desktop session due to focus stealing. When I open the browser, several dozen windows pop up (as expected) and relocate to their correct virtual desktops (as expected); however, as the windows begin to load, the most recently active Firefox window steals focus repeatedly. If I am, for instance, in the process of typing my password into my desktop e-mail client, a Firefox window may steal focus from the password dialog. In practice, this focus steal happens once every few seconds for several minutes.

I would prefer that Firefox would not steal focus while restoring a session. Does anyone have any suggestions for correcting this issue?

System:

Windows 10 pro 22h2 19045.3516

Intel i5-10200h with UHD 620

Driver 31.0.101.2125

Firefox ESR 115.3.0

When watching streams in firefox, I noticed that overall iGPU load is very high, up to 70%, a lot higher than watching 1080p movie with dedicated player.

I found that the firefox actually only shares 10~20 iGPU load, the rest are from DWM, which load is up to 40% sometimes.

Also found if I switch from the tab with streaming page to another normal webpage, DWM immediately drops its usage to about 2%, firefox still uses some load as it's still decoding. DWM usage rises if I switch back.

I tried force firefox to use nvidia dGPU, firefox does use nvidia card to decode, but the DWM problem said above still apply.

See attatched image as prove.

Whenever I launch Firefox, I get the error message "Firefox couldn't update automatically. Download the new version - you won't lose saved information or customisations." I download and install the .dmg for the new update, but I still get this error message whenever I launch Firefox. I used to be able to have updates installed automatically without requiring to manually download each Firefox version. Could someone please assist? Details below:

Firefox version: 117.0.1 (64-bit) MacOD: Ventura 13.5.2

Many thanks :-)

Right click on any link in Facebook asks for me to shutdown Firefox to open a new page. What is causing this? The same thing happens if I am in Thunderbird or Betterbird. It's OK to open a new tab but not restart Firefox.

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.

When searching queries, this error will come up; however, when searching full length URLs it works and sends me directly to the website. I've looked through the Q/As and they all recommend clearing cache/cookies and messing with the history settings to resolve the problem. However, after doing all that and messing with other settings I cannot seem to understand why this started to happen.

When in private browsing mode it works fine and I can ask whatever and I receive all the possible websites to click on. It's just on normal browsing that I receive the error message. Am I going to need to just uninstall Firefox and reinstall to fix this? Or maybe there's something else I can try out. Thanks!

Error in Question: The page isn’t redirecting properly Firefox has detected that the server is redirecting the request for this address in a way that will never complete. This problem can sometimes be caused by disabling or refusing to accept cookies.

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?

Maybe related: https://support.mozilla.org/en-US/questions/1363234

This has happened to me too many times and haven't found a solution to it. When I open Firefox after I have booted up my PC, my browser would either function as normal and everything is kept the same, or would act as if I am new to Firefox and reset my settings and add-ons. I tried re-installing the browser and creating new browser profile, yet those solutions that I've found hasn't worked. Any solutions would be helpful, thanks

(In the image provided, this is what happens at times when opening the browser after turning on my PC)

Updated to FF118 last night. Win 10.

Previously I started FF with -no-delevate to allow dragging of URLs to the desktop. In FF118, this switch no longer works.

Any solutions?

YouTube videos on Firefox getting slower and jerky. After refreshing Firefox (Settings -> Help -> More troubleshooting information -> Refresh Firefox), it is OK, but only for a short while. Then the problem starts again. Same YouTube videos are running fine with Chrome at the same time.

Running Windows 11 Pro (Clean windows setup not long ago and the issue was there from the beginning.) German Language Firefox 116.0.2 Build ID 20230805021307 Intel CPU i7-1360P, 16 GB RAM, 1TB M.2 SSD

Would really appreciate a solution for the issue because I really like Firefox!

Firefox worked fine until the latest update 115.3esr, at time it slows to a crawl... I am now sick and tired of Mozilla and Firefox, they are about to get the boot - my style, I've used them since about version 2.

Looking in the task manager Mozilla makes it look a disgrace, at time it's hard to get a fix on some entry's because they bounce up and down.

Firefox.exe 45,24K Firefox.exe 3,16K Firefox.exe 27,484K Firefox.exe 7,392K Firefox.exe 7,344K Firefox.exe 15,735K Firefox.exe 7,320K Firefox.exe 169,932K, I round it off to about 250MB

Does these look about right? Why can't they just have one .exe? (Win 7 Pro x64)

Thanks Dave

When i open a picture from a page, and want to save it on my computer, I right click on the picture to save it. At that very same second, Firefox freeze and I need to open the activity manager to close it.

What also confuse me there, when I find Firefox, there is a number behind the name, like: Firefox(7) Does it mean that 7 Firefox is opened in the background?

What is the problem?

To save a picture now, I need to use Edge.

In Firefox, the mouse becomes partially unresponsive to elements in the browser and on web pages. This happens after 15-30 minutes after starting up the browser. Common symptoms include:

- Unable to drag and drop elements properly, including text after highlighting it. - Sometimes, the mouse continues to hold elements while dragging. Pressing ESC temporarily fixes this. - Dropdown menus on websites do not drop down when hoovering over them - Other items on websites don't display items when hoovering over them

I have tried:

- Different mouses, including my laptop's trackpad - A Firefox fork, namely Waterfox, but it still occurs - Limited testing with other browsers. No problem occurs - Limited testing on desktop. No problem occurs - Entering Troubleshooting Mode on Firefox - Clearing cookies and cache - Reinstall Firefox (including installing from command line instead of the snap store) - Updated Firefox - Refreshed Firefox - About:Processes doesn't show anything using more than 10-15% of CPU at any one time - Limited testing with a new Firefox profile. No problem occurs - Disabled WebGL and Hardware Acceleration.

Temporary fix: Restarting Firefox, but the problem re-occurs shortly after use.

Using Ubuntu.

Any help would be greatly appreciated.
