FIX what seem to be CLEAR conflicts with relationship between platform and user's device (desktop, Dell Optiplex 790 in my case - that do NOT occur with Opera, otherwise) as WELL as aforementioned ATROCIOUS performance quality - BTW, this is the SECOND update / upgrade I've done in LESS than a WEEK.....

I just used pacman to update to the latest Firefox, but the tab crashed each time I open a new web page ( I can open settings, about:xxx and etc... ). I tried Troubleshoot Firefox crashes and it did not crash in troubleshoot mode. Then I tried extensions, themes and hardware acceleration issues to solve common Firefox problems https://support.mozilla.org/en-US/kb/troubleshoot-extensions-themes-to-fix-problems but non of these options solved the problem. I disabled all extensions, themes and hardware acceleration, and it reported the same error.

(SECOND occurrence of this problem; not sure HOW previous instance resolved - my short-term memory ISN'T the best at present!)

Have taken all recommended steps short of completely refreshing (renamed a file titled 'config.json.old' as it was the ONLY one with a 'json' filepath suffix) because I don't want to have to relocate (another) existing session / configured profile by trial & error if avoidable - 'cookies' were removed along with history / cache cleared; reset / deleted related browser registry entries as directed, activated ' Troubleshooting / Safe Mode' contingency and STILL can't download anything (additionally, tried to do so with and without limited-time Malwarebytes web protections).....want to CONTINUE using Version 95 because by ALL indications and from what I'm seeing in Comments, my instincts about newer ones - were sound, WELL-informed.....please advise ASAP? Thanks!

Over the last couple of days we are seeing instances of Firefox just disappearing from Windows 10 and just today from a Windows 7 pc. When I say disappears, the desktop shortcut becomes dead, click on it and a prompt to search for firefox.exe comes up. Checking Add / Remove programs shows Firefox to be installed. Checking C:\Program Files\Mozilla Firefox reveals empty folders with the exception of a couple of text files. Trying to reinstall the Firefox app, we are prompted with a message that Firefox.exe can't be found, and there is a button to browse for it. The only solution we have found for this is to copy the C:\Program Files\Mozilla Firefox folder from a working pc, and we just received a call from a user we did this for telling us that it is gone again. Any ideas?

Thanks.....

We have checked for viruses.

Hi there, I'm having trouble opening firefox that suddenly didn't open after I've used it as usual. When I've closed it, I've put the macbook on sleep mode and then reopen it after 10 minutes and tried to open firefox as always. It didn't. I'm trying to figure it out and I've followed all the possible paths on Mozzilla's support and others blogs, but none of them worked out. I've tried also to uninstall and re install firefox from scratch, but nothing happens: I still get the message. At this point I don't care if I need a fresh start, I have a bookmark's backups so, how can I really uninstall Firefox and install it from the beginning? Is there a hidden folder I'm missing? Thank you in advance

Hi there,

I have a brand new Win 10 MS Surface 4 Laptop, and have tried downloading and installing various versions of Firefox:

From the the Windows Store Direct downloads (via MS Edge): Mozilla FF Win 64 Mozilla FF Win 64 MSI Mozilla FF Win 32

I have completely uninstalled and attempted to re-install each in turn. Attempts to open FF through desktop shortcut, Start Menu and Win-R FF.exe all seem to start but only ever get the briefest flash of a blue line along the Taskbar then nothing. Same happens starting Shift-Shortcut.

Nothing shows in Task Manager either after any start method. I'm pretty sure I'm not in 'S Mode' as I've been able to download, install and run WhatsApp Web, but I'm not wholly convinced I've cleared that up fully.

Thanks! E

Firefox has WIFI stability issues. Chrome remains stable, but Firefox loses connectivity every 5 to 10 minutes. A refresh is required and often that does not solve the issue. A complete reboot of Firefox is required.

Hello all, after reinstallation my Firefox 88.0.1 on Windows 10 64 Bit does not go online. I can't open the settings. Other browsers like Opera and Edge are ok on the computer. Does anybody have any hints ? Many thanks, Volker

Hi, volunteers!

About an every every hour or two, Firefox shows a compelled "Restart required" page with a "Firefox has just been updated in the background" message, which yet absolutely sure has nothing to do with disabled automatic updates.

These and pyllyukko's user.js preferences have been set:

• browser.cache.disk.enable;false
• browser.cache.disk_cache_ssl;false
• browser.cache.memory.capacity;5000000 # -1
• browser.cache.memory.enable;true

The page is shown either hard or solid state drive is used with 8 GB RAM on board, `free -h` shows more than enough. "Storage disk location" value for `memory` and `disk` (except `appcache`) from the `about:cache` page is "none, only stored in memory".

Appreciate your time and efforts, this message haunts me no matter what for so long.

MacOS Catalina 10.15.7 Firefox 88.0.1 (64-bit)

All recent Firefox versions have killer bugs.

A new one was actually trying to login here. The error message said 'Cookies must be enabled' and I couldn't get further. Cookies *were* enabled! I shut down Firefox, and re-opened, and all was then OK.

. Web pages with scripts are often completely blank. . Pop-ups are often blank. If not they often don't work, like (critically) Ebay login. . View source (CMD U) works for new pages. However doesn't update if the source page changes.

 I do use <CMD U> from the changed front page.

A silly one is that the keypress to 'Copy Link' was deviously 'A', but not shown. It has now changed to 'L' and still not shown. Why? I very much prefer Firefox, and all the many shortcuts are memorised (well bar 'L' (8-)# )

However I so often now have to use Safari or Chrome to get around the bugs. This is a pain as the interfaces are different, and specifically 'View Source' never has a shortcut key. They also have their own bugs!

I've had Firefox running on this PC for a couple of years and started running into problems with it. I've tried refreshing, reinstalling, restoring the machine back to prior system restore points, nothing seems to work. It all seems to revolve around the ntdll.dll. I've included some event viewer info and the content of Report.wer.

It seems Firefox has been banned from this machine.

Let me know if there is anything else I should provide.

Thanks.

I am testing FF91esr for deployment later this year. Having a lot of grief with it.

For context; On most of our PCs the profile folder is NOT in the %APPDATA% folder. It lives on a different drive, typically drive F:\

This allows us a lot of freedom to restore a users C:\ drive without messing up the Firefox profile, or losing recent information, for example. We do the same for Thunderbird and several other applications.

The profile.ini file does live in its default location and points to the relavant folder path=F:\Users\<username>\profiles\<profilename> IsRelative=0

We backup a users PC with a comprehensive script which copies the profile.ini and Profiles folder. The group policy is also backed up, and in that policy we have set to use legacy profiles.

When we build a new PC for a user we restore those backups in the hope that the user will take up where they left off. For example, their browser history will be at the point is was when they left the PC.

The whole process is pretty automated. However, with FF91esr I cannot get it to use the folder we backed up. It ignores what's in the profiles.ini file and creates a new profile in the default location, set's it as default and of course sets IsRelative=1.

I tried several combinations of things to try to stop this, but in the end the ONLY way I could get it to use the restored profile was to go to about:profiles, create a new profile, point it to the folder where the restored profile is located, restart using the new browser, then via about:profiles, delete the bogus profile (of course having set the restored profile as default).

I'm not going to sit at 250 PCs doing that. It's crazy.

How can I get FF to use the restored profile folder and stop it endlessly creating new profile folders?

So far I've only tested with clean installs of FF91esr, so this is not an issue with different versions of profiles. But I am concerned over what's going to happen when I update Firefox on a PC...

Hi, I'm running Firefox on Ubuntu 20.04.2 LTS Gnome Version 336.38. For at least one month now Firefox has stopped working. When I start Firefox normaly (or in the tor-browser bundle) the Firefox-Window opens but no page is loaded. No matter what page I navigate to, nothing happens. I can't even open the firefox settings. I updadet from the normal version to 89.0 but still nothing working. Anyone got any ideas?

I am using Firefox-ESR on my Kali linux distro. I am unable to load any webpages on Firefox but other browsers can load. I tried all the steps like clearing every history, cache, etc. I have even reinstalled several times but it is only loads for 2-3 seconds and shows a white blank page and nothing else. I have gone through your tutorial of "Firefox can't load but other browsers can" but it is not helping. There is no problem of proxy either.

Edit Update : I need the Firefox-ESR installed as default. I downloaded new version Firefox-ESR=78.11.0esr from Firefox download page and it loads webpages. But the latest Firefox downloaded from apt is Firefox-ESR=78.10.0esr. I cannot update Firefox as new downloaded version has executable file name as 'firefox' but default has executable file as 'firefox-esr' in '/usr/lib'. I have two different versions of Firefox-ESR installed now because of the installation procedure given in Firefox install tutorial page. I am also not able to find the new version browser in 'x-www-browser' in 'update-alternatives' to set it as default. I want the Firefox installed with all features as default one. I think I have not installed new version of Firefox-ESR correctly. I just want to update Firefox but not to install another version of it. Thank you.

Hi All! Need some help for a client please :) iMac 27in (late 2013) Processor = 3.2Ghz Quad Core Intel Core i5 Memory = 8GB DDR3 MacOS Catalina = 10.15.7 1TB HDD Not sure if this is a MacOS thing or a Firefox thing. My client would prefer to use Firefox, currently using Chrome. However - whenever they close Chrome or shutdown / restart the computer, Firefox looses everything and they have to re-import all the data from Chrome. This is happening on a continual basis. It's simply not saving any data / settings that are imported from Chrome.

Thanks!

Sir/Ma'am,

My system is a standard install, and when I open Firefox, click Help, About Firefox, and then click the linked word (Mozilla) "Firefox is designed by Mozilla" it takes me to "www firefox com cn" ?

Is the version of Firefox in the Linux repositories the China version with an American facelift?

I know you all do not have command and control of this, but I thought someone should be aware that the default Firefox browser for Linux installs seems to be the CCP Firefox and not American version. With all the CISA activity, it might be something to look into.
