Hi I have a Shopify account and since the Firefox 99 update my Shopify shop page doesn't load any more, showing an error message. I have had to download Chrome in order to access my shop - really annoying. Have anyone been able to troubleshoot the problem? I find it really affects my ability to do business and I am feeling let down by Firefox. I am adding a screenshot of the error message. I can access my shop without any trouble on Edge or Opera browsers. Firefox is the only one having issue...

Firefox is up to date. All other sites work. Everything worked fine when i went to sleep, trying to do some research on youtube right now and all I get is the error message.

In Firefox, my instructor and student grade sheet no longer displays the horizontal scroll bar to bring more data extended off to the right of the page into view. I have an image attached where the scroll bar should be present. This begin in May sometime, and I'm not sure how to fix. I have tried re-installing fresh a few times, and removed any custom settings that might have been in place. Any and all help would be VERY appreciated as one of colleagues is super frustrated and I would love to find out an answer for both him and myself.

All bookmarks and tabs will not open on Firefox version 101. I can only work in troubleshooting mode. I have re-installed an earlier version, but as soon as Firefox starts, it updates to 101. I am running a Windows 10 - 64 bit OS.

Can you please tell me a permanent fix that will allow me to run Firefox normally?

Hi,

Today when I tried to login to my mail my passwords & emails where not there, when I went to my Firefox passwords page it was empty. I tried reinstalling Firefox multiple time to check if it works. I don't know what to do as all my bank/company logins where saved & i don't remember most of them. What should i do to get this fixed.

Please explain and advise how to resolve the problem. Thank you! Besides, why there is a mention in red that my account is not active. I have been using Firefox constantly for several years. Any explanation?

Hi. I'm experiencing Firefox crashes since version 101. I'm using (old) CentOS 7.3 with GNOME desktop environment. Interesting thing is that these crashes do not happen in KDE or XFCE desktop environments. Further, I have found that if I start Firefox with 'env -i' the crashes also do not happen. I am talking about this category of crashes: https://crash-stats.mozilla.org/signature/?product=Firefox&signature=webrender%3A%3Arender_api%3A%3ATransaction%3A%3Aset_document_view&date=%3E%3D2022-05-31T12%3A36%3A00.000Z&date=%3C2022-06-07T12%3A36%3A00.000Z&_columns=date&_columns=product&_columns=version&_columns=build_id&_columns=platform&_columns=reason&_columns=address&_columns=install_time&_columns=startup_crash&_sort=-date&_sort=-version&page=1 They have all in common that some nonsensical window size was trying to be allocated (for example: Attempting to create a 28117x32840 window/document). This, however, fixes it for me (starting firefox from the terminal, shell is bash): env -i DISPLAY=:0 ./firefox/firefox I have tried it with Firefox 101 and with beta 102b4 - it's the same.

hey folks,

since today firefox wont load any websites out of troubleshoot mode. not even settings/ about:config. if i open a page in a new tab it just stays blank and nothing is happening.

in troubleshoot mode i turned off hardware acceleration - nothing changed after restart. i updated the runtime file "Visual Studio 2015, 2017, 2019, and 2022", which is suggested in different help-posts, i deactivated all addons, i created a new profile and also tried an imported one from eralier today - so far nothing has worked.

i also reinstalled firefox with version 99/ version 101 two times, after i cleared %APPDATA%-data.

im also just using windows defender as antivir.

please elp, i'm out of ideas.

Hi, I use the Outlook web interface on firefox. I keep running into a strange bug. I'll start typing an e-mail message, and all of a sudden, my keystrokes are interpreted as commands instead of text. For instance, I'll type a word with an "n" in it, like "and", and somehow after I type the "a", the interface starts grabbing keystrokes away from the text field, so when I hit "n", it creates a new message, and the "d" ends up going into the text field of this new message. It's very frustrating, because I can't type more than a couple of sentences before the message and interface get screwed up. I've seen this misbehavior for a while, through several updates of firefox. No other web app behaves this way.

This has been happening for many months now and I can't wait for an update to fix it unless it's going to happen soon.

Should I uninstall Firefox and switch to another browser or is this something that's going to fix soon???!!!???

It's going to be a project to switch so once I do it I'm never coming back. I currently have firefox on 10 different computers I work on between my home and office. I can't live with these glitches anymore!!!!

Hi, my Firefox on Win10 doesn't work, I've been forced to go back to Chrome. After a crash in Win10, Firefox doesn't work anymore: it opens, be it launched by me or by other programs, but it just sits there, blank, doing nothing. It is impossible to interact with menus and everything. Task Manager shows two open instances of the browser, using RAM, but the browser doesn't do anything. It doesn't "crash" and it doesn't freeze, it just stays like that. If I quit it and try opening it again the PC tells me it's open already, and Task Manager shows a couple instances staying there after quitting it, as if it stayed stuck. I tried resetting it from the Apps settings of Windows, but nothing happened, I tried uninstalling it and then installing it again, but nothing happened. Restarting the PC a couple of times changed nothing. In the end, I had to go back to Chrome and even put it as default browser because all programs were calling up Firefox which stayed unresponsive. Anybody knows what I should do in a case like this?

My WIN7 computer RAM/CPU is being totally overwhelmed by about 5 to 15 times too many process instances that are probably due to Fission (that I have already set Fission autostart to false) and/or a contributing factor may be that there are 3 instances of Firefox showing up in my Default Programs when only 1 instance shows up for everything else.

Hope you can help with this Firefox browser situation because I really would hate to have to rely on an Internet browser provided by the corruptible rich of this country/world.

Please provide some relief as soon as you can.

TIA, Tim

Since the Firefox 99 update loading some pages (for example, the Gmail sign-in page) using Firefox on my Linux Mint machine, that I'm running a VNC remote desktop session on, results in a crash.

Crash report ID: bp-5dc1e89d-dc1f-40f2-9dbe-7f4380220419

I've tried running Firefox in safe-mode and the crash doesn't happen, but turning off hardware acceleration, swapping to default themes, removing all extensions, and completely removing Firefox and the .mozilla folder and then re-installing Firefox have not changed the crash behaviour in the absence of the safe-mode flag.

I would appreciate help in identifying what other paths of investigation I can take.

Used Firefox for many years with the inbuilt Microsoft on screen keyboard without problem.

After updating Firefox a couple of days ago to the 100 edition when I enter text in Google and press enter Firefox instantly crashes.

If I use the touch screen keyboard in windows its fine.

Using windows 10 fully updated.

Any help appreciated.

I routinely record short screencasts with Kazam, and I can't watch my own videos after posting them on sites like GitHub because Firefox says "Video can't be played because the file is corrupt". Or for example when I upload them to sites like ezgif to convert them to a GIF, which works just fine because, well, the file is not corrupt. Other browsers like Chromium play them just fine.

Apparently the "OpenH264 Video Codec provided by Cisco Systems, Inc" is properly enabled in my system. This has been happening to me for months or years, but only today I decided to open a thread here.

There are two things here:

1. Firefox can't play the file. I'm sure there's some sort of misconfiguration on my side, or bad defaults, or a missing plugin, or similar. 2. Firefox shows a misleading message. The file is not corrupt! The root cause is something else.

Any advice on how to fix the first one?

For some reason I'm no longer able to open a new browser window either by right-clicking the dock icon or under the File menu. The only option available is to open a new private window. I can, however, move a tab to a new window.

Is there any was we can add back the functionality to just open a new "normal/unprivate" window?

I use Firefox on Linux Debian 11 (Bullseye). After a recent automatic update to Firefox 91.10.0esr, some websites will not load (just sit with a blank page, showing flicking loading symbol). Examples are ocado.com and abelandcole.co.uk. I have tried all the usual things to fix, including, switching off VPN, clearing cookies and caches, running in safe mode, all with no success. Both sites run fine in Vivaldi and Brave. I have eventually got the pages to load by disabling IPv6 in Firefox. Clearly there is a problem with 91.10.0esr. I'm not sure whether the workaround of disabling IPv6 might cause other problems or weaken security or privacy?

I have been having so many problems with Google Mail that I have switched to another browser. I keep getting error messages such as,"Oops," " Retry in x seconds," "You may have network problems," etc.

I also am unable to send messages.

I understand that this is a result of Firefox's latest update.

I tried the following suggestion: "Here's how you can disable that feature in case you don't find a more convenient workaround:

(A) In a new tab, type or paste about:config in the address bar and press Enter/Return. Click the button accepting the risk.

More info on about:config: Configuration Editor for Firefox. Please keep in mind that changes made through this back door aren't fully supported and aren't guaranteed to continue working in the future.

(B) In the search box in the page, type or paste security.tls.enable_0rtt_data and pause while the list is filtered

(C) Double-click the preference to switch the value from true to false "

However, this worked for a short time and then I started getting the "Oops" message again.

I cannot use GMail on Firefox.

Please, please fix the problem.

For the past few weeks Firefox has become VERY slow, refuses to load many web pages, displays security messages and is generally unusable. I have tried solutions from the troubleshooting page, reset Firefox, checked time and date but nothing makes any difference. Other browsers work as normal. Any suggestions please?
