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!

You know how you can type a URL and then Ctr+Enter and FF autopopulates the .com? Well years ago "Shift+Enter" autopopulated ".net" and "Ctrl+Shift+Enter" autopopulated ".org".

I really liked that feature. I know a lot of people don't, or don't see its point; that's not important.

About three years ago, I added UserChrome.js and enable-UserChrome.js , which acomplished the two autopuopulating tasks quite nicely.

Until about four weeks ago. I don't know if an FF update stopped reading those two .js files, or if there's a conflict somewhere else, or what. I don't know where to begin - other than posting here for help.

Thanks in advance!

• UserChrome.js is in the subdirectory: C:\Users\[ME]\AppData\Roaming\Mozilla\Firefox\Profiles\gaydtewj.default-release-1
• enable-UserChrome.js is in C:\Program Files\Internet Shenanigans\Mozilla Firefox\defaults\pref (firefox.exe is in C:\Program Files\Internet Shenanigans\Mozilla Firefox )

I'm running 115.2.1esr x64 bit on Windows 7 pro. games on Facebook will not load I get 'Your browser does not support graphics API "WebGL2" error'.

In 'about:config' shows GL2 is enabled, yet Facebook games works with Google Chrome and MS Edge browsers, this seems to point to a Firefox issue.

I removed Firefox entirely, cleaning the registry etc, installed the latest version and get the same result.

Can anyone throw light on this? If need be I'll enclose

the troubleshooting info. 

Thanks, Dave

I am using https://infiniteajaxscroll.com on my website https://madway.net . When I scroll down and new set of topics loads, if it contains html5 video it will not load, stay loading. Works fine on Edge browser and Android browser.

Using latest Firefox.

Since 117(Beta)I have an issue with Firefox refusing to apply the update it downloaded. I've tried searching left and right on the internet for a solution and one does work which is installing the newer version of the browser each time myself. But this is ofcourse not a solution in the long run.

It tries now to apply the update 118b9 to stable version 118 and it did downloaded just fine and asked me if I wanted to close the program to let it update which always worked. I've tried different DNS to see if that could be the problem, tried a clean default profile to see if that helped, I haven't tried uninstalling it and reinstalling it, due to me losing my passwords and what not.

I also tried to run the stable version to see if the issue was still there and it is still there, so me using the beta channel isn't the issue here.

Keep getting this on a number of websites. Most of them I have used for years. Can't give the websites as there are too many but some are pitchsidemanager.com, hattrick.org, skysports.com and sportinglife.com . Just four of at least 14 give the Hmm. We’re having trouble finding that site message. I use No Proxy and have my anti-virus turned off when I get the message. I have tried various other proxy settings but the same thing happens. The thing is that I have to keep refreshing the page until it does actually connect and that can take a good few minutes. Sometimes I have to restart the browser. Why is this happening since the last few updates?

I don't know when it started (quite awhile), but when I go to some websites even in FF safe mode, I wait a long time but get nothing displayed and it stops spinning/waiting (the circle arrow upper left stops). Occasionally when I reload, it comes up but usually it doesn't. Other websites it works fine.

In fact, if I browse to some websites, sit and wait awhile, then go to chrome or edge, type in the same website, the page displays even while FF is sitting there waiting.

ebay.com seems to work great, but for instance this morning, this one doesn't: https://www.crowdpac.com/news/741938 but sometimes this works: https://www.crowdpac.com then try it again (refresh) and it never responds.

And in fact, I'm using Edge to submit this question because when I browsed to https://support.mozilla.org/en-US/questions/new/desktop#search in Firefox/Safe and clicked on the Sign-In/Up button, nothing happened. With Edge it worked fine and I'm able to type this in.

I am reaching out to the Mozilla Firefox community for assistance and guidance in resolving this issue. If you have encountered a similar problem with Mozilla Firefox or have expertise in troubleshooting Firefox, your insights and recommendations would be highly appreciated.

Please feel free to share your experiences, potential solutions, or steps to diagnose and resolve this problem. Your assistance will be invaluable in helping me address this Mozilla Firefox usage issue effectively.

Firefox tabs keep crashing repeatedly and sporadically. I had the most recent version on my mac. I have a MacBook Pro (13-inch, Mid 2012) I restarted Firefox various times, restarted the computer, tried troublehsooting mode, uninstalled Firefox and installed 115.2.1esr . Problem continues even in troubleshooting mode.

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.

I just purchased bose 700s and I can hear noises for a fraction of a second every time I move the video forward beyond what is already in the buffer. On chrome the scrubbing is perfectly fine.

It is really annoying, any help? Thanks!

pd. I noticed this doesn't happen with another pair of headphones so the 700s in themselves play a factor. However it never happens when using chrome so I guess is the combination of the two-

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)

This has happened a few times before after a Firefox update, but the most recent occurrence was after the update to version 117.0.1. My mouse wheel will not scroll in the bookmarks drop down menu, I have to use the up and down arrows in the drop down menu which is very slow. When the scroll wheel did work in the past, I could be scrolling and then move the cursor to the up or down arrows and scroll even faster still using the scroll wheel and get to the folder I want a lot quicker. The scroll wheel works normally while scrolling through webpages, the only place it doesn't scroll is the bookmarks drop down menu. I'm running Firefox version 117.0.1 (64 bit) on a Windows 10 notebook PC. Any help would be greatly appreciated, thank you.

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.

This morning, I brought up Firefox and found my bookmarks (including the toolbar) had vanished. I tried restoring my profile folder, but that didn't help. I also tried restoring the bookmarks from Firefox's own backups, but I got some "Unable to process backup file." messages. What do I do now?

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.
