Firefox Support Forum

Yo, Linux sysadmin here and been using Firefox forever.  Surprisingly I have this ancient 12 year old System76 laptop that I use for nearly everything (got a newer Lenovo that I been meaning to switch to but no time).

Using Debian 12/13 with Gnome 43.6/X11.  Can't quite figure out this issue though.  Besides being a sysadmin, can have other side jobs/projects going on as well, so can have 5-10 windows open in different workspaces, sometimes with hundreds of tabs all together (big fan of the Auto Tab Discard add-on and about:memory Minimize Memory Usage to keep performance up and resource usage low).

Been noticing this issue for the last few versions where suddenly, after random amount of Firefox uptime (can be after days of perfect performance) my keyboard input aka typing gets extremely laggy, like 30 seconds behind for all keystrokes, except: Ctrl-F instantly brings up the Find in Page bar, and Ctrl-C instantly copies to clipboard.  Ctrl-V, however, 30 seconds lag, Ctrl-A also....  Mouse is fine though and can right-click and paste instantly or use other menu options.  Happens anywhere in Firefox too: in address bar, in the find text box, in the preferences, in my saved passwords, haven't found a place with no lag.

Have searched around for some hours now and only found suggestions to disable accessibility service, but accessibility service has already been disabled for a while now.  Everything else in my Gnome desktop session is running fine.  Restarting Firefox temporarily solves the issue but is highly annoying and interruptive with as much as I have going on sometimes.  Due to timing randomness, starting Firefox without certain add-ons is impossible as I can't spend days at a time without any of them.  Just have to open a text editor and type what I need to in there, then paste with mouse, until I can find a good stopping place to restart Firefox.

Have included most of the info from about:support in the Troubleshooting Information.  Spent quite a bit of time looking at all my modified preferences, nothing popped out but if there's something you think I could include to help, let me know. Thanks

So my firefox recently started freezing while watching live streams on both youtube and kick. It'll freeze and buffer forever until I either refresh (kick) or hit the grey "live" button on youtube and the whole freezing thing repeats again after 2 minutes. Add-ons and internet speeds attached

Since the last FF update (115.5esr, Windows 8.1 Pro) I keep getting the following error message when I try to access one particular website:

The page isn’t redirecting properly An error occurred during a connection to www.doordash.com.

   This problem can sometimes be caused by disabling or refusing to accept cookies.

I have tried virtually all the solutions suggested online. I have cleared my cache, deleted cookies and site data, and I have tried to access the site using Troubleshooting mode, all to no avail. I contacted support for the particular website and they have no difficulty accessing the site with FF.

I can access the site in question with the Chrome browser, so the issue would appear to lie with Mozilla. I use this particular site frequently and would much prefer to continue to access it using it with FF, as I have done for over a year. I just installed Chrome on my Windows 8.1 Pro PC solely for the purposes of accessing this one website.

Help in resolving this issue would be greatly appreciated.

When I open firefox it opens on the "success" page it should open on my selected page Yahoo.com

this happened after I ran the "refresh firefox" option

My Simple Tab Groups disappeared after one of the recent Firefox updates. This has happened before. Now, after considerable time rebuilding my simple tab groups, when I get a notification that a new version of Firefox is available, I dismiss it. I am afraid of losing them again.

Have you heard this before? Has the issue been addressed? Is it fixed? Is it safe to update without losing the tab groups? Is there a way to back them up and restore them later if they crash?

TRYING TO OPEN A SAVING ACCOUNT WITH BANK OF MONTREAL https://www.bmo.com/main/personal/bank-accounts/ CLICK ON THIS ONE: Savings Amplifier Account AFTER CLICKING THIS WINDOW APPEARS: https://www.bmo.com/main/personal/bank-accounts/getting-started/?rg=BMO&spc=7880184&ofid=SAASTAND001&lang=en IT TELLS ME TO USE ANOTHER BROWSER LIKE Firefox..... BUT I’M USING FIREFOX. I DON’T USE ANY OTHER BROWSER. HOW CAN I SOLVE THIS ISSUE?

Hello, the description is the same as in the title: Firefox is slowing down significantly while I have "more" demanding games running I'm talking about a game like assassin's creed mirage mostly on ultra for example.

It all started with the purchase of a new computer, on the previous one I did not encounter such a problem. It manifests itself in the way that the video is slightly desynchronized with the sound + I can see a significant difference (delay) when scrolling the pages.

My current rig: Intel Core i7-14700KF Nvidia RTX 4080 32GB of ram running at 6000mhz (G Skill Intl F5-7200J3445G162x16GB ) 2x Kingston SKC3000D2048G 2TB

I understand that the GPU focuses on the game but can't it be improved somehow? The rest of the applications on the computer work normally In my opinion, the computer does not seem so weak that it cannot handle Firefox and the game simultaneously.

Send help please 😊

i have just downloaded Firefox and i go to open in and it flashes open an close immediately. the occurs every time that i open the program. i have reinstalled it multiple times to see if that's the issue, used the Microsoft store to download it, the website, i tried to get the beta that didn't help and i was just wondering what the issues was and wondering if you could. i looked in the error message folder as well and its empty.

I have been receiving the following error code 'PR_END_OF_FILE_ERROR' on several website on my Firefox browser. Sometime, not all the time, I get the same error message while trying to use YouTube, while other times the site loads but says that I am offline and no internet connection. I have done all of the fixes that they say to use online and nothing seems to work. YouTube will occasionally work but none of the thumbnails will show up. Then there are other site that work fine.

Mozilla is crashing since last 3 days and it is often

Please do the needful urgently.

hi Team,

We are working on xxx organization and for one of our core applications experienced suspicious activity since November 22, 2023, while users leveraging Firefox browser version 119.0 where customer made multiple attempts to perform sequence of flow and got dropped. Around 99% of our customer got dropped ever since Nov 22. We are not sure if its due browser or any other suspicious issue.

however, we would like to understand from your other customer experience perspective, have we encountered any bad user experience using Firefox browser version 119.0 / or do we have any bug encountered and recently had a fix? 

2. Another question, If in case was a fix for Firefox version 119.0 will the customer browser automatically gets updated ?

It would be great if you can help us to share these details so that we can investigate further.

Whenever I navigate in a video or go fullscreen on YouTube there's a painfully loud crackle, I use the site frequently so I'd appreciate a fix because it's very painful for my ears.

The problem is:

1. in Firefox browser with a saved to hard drive file the HTML file is default to Firefox and on double clicking goes into the mask (incomplete missing graphics) 2. click on desired filed nothing happens 3. reset to MS edge as the default browser and functionality is there...

Is there a setting in Firefox that I am not seeing?

Thanks

I've been unable to play amazon prime videos on firefox for some time now. It comes up with error message 'video unavailable'. I've followed all the advice on amazon website and google searches but nothing works. what do i do ? (this is on asus zenbook laptop) I've tried checking for updates on firefox and add ons, restarting Firefox, restarting laptop, clearing cache , checking DRM settings and deactivating proxy servers.

A couple users at our site intermittently receive a SSL_ERROR_BAD_MAC_ALERT error when navigating to Google in Firefox. This happens in Version 99.0.1 (64-bit) on Windows 10 computers. When the issue occurs, users can navigate to other websites without issues. Navigating to Google in a different browser works no problem. Restarting the browser will resolve the issue. Clearing cookies and site data has no effect. Users can also refresh the page after some time and the issue will go away.

Any idea as to why this is happening?

I recently installed new pc with fresh Firefox Developer Edition. Then I transfered the profile folder from old pc to the new pc. All bookmarks, addons, etc is there. Just the XULRunner popup appears only on the new pc. I uninstalled firefox on the new pc again and reinstalled it with profile cleaning. After profile cleaning firefox got faster and addons got removed. But the XULRunner popup keeps appearing. When I go to taskscheduler and trigger the "Firefox Developer Edition Background Update CA9422711AE1A81C" again, the XULRunner popup appears. Removing this taskscheduler and Firefox keeps readding it and the XULRunner popup are back. Any idea how I can get rid of the XULRunner popup?

Immediately on update to 96.0 this afternoon, multiple sites failed to load - Google(Maps, News etc), Yahoo, Flightradar24 etc - others partially loaded - then sat there blank. Explanation of errors is NOT clear -

Is it possible to revert to previous version? Everything seems to work fine when using EDGE!
