## Firefox neither can use profile folder nor create new one in main user account

Hello to all,

as I am running out of ideas (see all actions already taken below ...) I wonder if the community has any idea what might be the solution? Forum search here did not reveal any entry with my particular circumstances as it affects only the current user account on my computer.

My Firefox profile folder is rather old as some of the files in its three different profiles date back to 2005. The whole Firefox folder has been migrated from two previous Macs to the current machine which itself now uses its third hard drive. Therefore a folder rights issue might be possible but in my opinion not very likely.

As I am used to report software bugs I have chosen to write it down like a bug report, so mea culpa if this is not the expected format on this platform. But I am a little desperate and miss my highly customised Firefox environment.

Best regards from Berlin/Germany and many thanks in advance

Carsten

Describe the problem you have:

"Firefox" no longer launches successfully, claiming that there is no profile. However, the profile folder has not been manually renamed, moved or modified.

If possible, include steps to reproduce the problem:

- Start Firefox program (Dock, Finder, commend line) - Error message appears immediately

Expected behavior:

- Program launches with all data and settings from the profile folder.

Observed behavior:

- Error message: "Profile not available. Your profile "Firefox" cannot be loaded. It may not exist or access is not possible."

Program version: - Firefox 78.8.0esr (System language: German, de-DE)

Platform: ProductName: Mac OS X ProductVersion: 10.14.6 BuildVersion: 18G8022

Please provide any additional information below: - Program was deleted and reinstalled: Firefox again starts only with error message

- tried all steps from "https://support.mozilla.org/en-US/kb/how-run-firefox-when-profile-missing-inaccessible" with no success

- tried to start in safe mode: "/Applications/Firefox.app/Contents/MacOS/firefox-bin -safe-mode" with no success

- tried same computer, user account of local admin: Firefox starts without error message

- tried same computer, user account of another standard user, copy of Firefox profile folder pasted to appropriate folder: Firefox starts without error message with almost all data and settings. Missing: different GUI theme and all Addons icons in the toolbar

- tried with separate ProfileManager.app: regardless of any selected checkbox, the same error message is always displayed

## Firefox 87 on Linux Mint 20.1 opens nothing, including about: and local files

Hello!

I've upgraded my PC to Mint 20.1 and applied the latest upgrade to Firefox 87 also. Prior to these last upgrades I could use Firefox, ie after upgrade to Mint 20.1 Firefox worked then, after applying the latest upgrades in the Mint Upgrade Manager, including a Firefox one, it did not.

Now Firefox will not open any pages anywhere. This includes the about:preferences page (thus obviating almost all advice I've seen) and even a local two-line "Hello world" HTML page in my local Documents directory.

Nothing displays at all, not even an address in the address bar (unless I type one in but that makes no difference). See the attached, unexciting, screenshot. Things I've tried already:

• Refreshing Firefox
• Clearing the cache
• Copying over a profile into the .Mozilla folder from a version that worked before the upgrade
• Deleting and reinstalling from scratch
• Trying the first four items again on the fresh reinstall
• Installing V85 (which works on my laptop)
• Trying the first four items yet again on V85
• Installing V84, which was the version prior to the upgrade on my PC
• Going back to V87 fresh then re-starting Linux in safe mode and trying again
• Looking at the traffic in Wireshark (didn't really help, that one)
• Shouting at the screen (was even less helpful than Wireshark)

In no case is there any change in behaviour. The only thing that will display is the "troubleshooting" page and I attach here the text from that.

Am I the only person to have experienced this lately? Similar reports for much older versions exists but they're mostly for Windows so no use to me.

So -- can anyone suggest anything? Bear in mind I can't get to any about: pages nor do any web developer options work.

All the best

When I open FF, the window only displays the top menus. If I click the Green dot it will then open full screen. Pressing the green dot once again only displays that 1 inch window. The problem does not occur in safe mode for Firefox. I turned off all of my extensions and turned off hardware Accelerator mode yet the problem still happens.

This just began yesterday and I don't believe I installed anything.

Since two days I can't connect to any websites or getting options page directly. Enter about:config, about:preferences also doesnt work in the url bar. (The url is also suggesting theses pages.)

I already reset Firefox, changed the profile, cache cleared. Event a full purge with apt purge firefox and removing any firefox files didnt resolved my problem.

If I'm clicking in the top right menu>preferences, this doesnt launch the tab.

The only thing working is passing by the top right menu>help>troubleshooting informations. Only on this page I can replace about:support by about:preferences in the url bar and now I can get the preferences... If I try to enter a url like google.com in the same place, it's loading but spinning indefinitely.

Firefox is the only browser getting this kind of problem.

Downgrading to 86.0 release or use developper edition didnt work.

It's the first time in so many years that I'm getting this. I don't know where the solution can be.

Hi everyone,

Thanks a lot for taking time reading this! :)

I have the following problem with my firefox on Kubuntu 20.04 on my laptop: since a couple of weeks, firefox opens normaly after rebooting, remembered all tabs and my firefox account etc., but it's just not loading anything. I can still type in a web adress or something in the search, I can also still select the drop-down menu on the right ("Open menu") and select e.g. "Settings", but nothing happens afterwords. Same problem for all websites. Some of the main buttons are also not functional (refresh, back/forward). I attached a screenshot from the "empty" firefox (but not sure if that's of any help anyways ;) ).

I tested a couple of things so far, nothing helped:

1) Internet is working, I tested ping, apt is working as well as a differnt browser I installed now).

2) I reinstalled firefox completely by running the following commands:

      sudo apt update
sudo apt purge firefox // sudo apt --purge autoremove firefox
sudo rm -rf .mozilla
reboot
sudo apt update
sudo apt install firefox

      (Since I removed the profile folder, the standard tab and bookmarks open/show after starting firefox now, as expeced. I'm also not longer logged in.)


3) By starting firefox via the console, no error messages were shown

4) I created a second ubuntu unser profile, to test if firefox would work there: it doesn't

5) Since I have a dualboot with Win10/Kubuntu 20.04, I started Windows and tested firefox there: it is working as usual.

6) I also obviously tried to google this problem, but either I put the wrong keywords in or this problem is pretty unique/new?

If you need any further information on my system, I'm happy to provide them! Thanks a lot for any recommendations and further ideas, what to do! I'm pretty much desperate for a solution by now, as during home office a not well working system is a pain! ;)

Thanks and stay safe, Katrin

Hi there,

We use GMail/ Calendar/ Drive for our business. On the official account, I am seeing a continuous - multi-day - situation where my Google Drive won't load when I point my browser to it unless I do at least one refresh after getting to Drive and waiting for my list of folders and documents to show up.

In the mean time, the following error shows upon on the bottom left of my screen - "The server encountered an error. Please try again later." - this has persisted for over 2 weeks when I restarted using Fiefox earlier this month. I do not get this error when using Chrome or Safari.

Today, I am also not able to see the user who last modified a document or a folder last, as you can see in the image below.

Please tell me what I can do to fix this issue.

a similar problem in a browser installed with apt (but when running in safe mode, there is no problem, and manually disabling extensions and cleaning / refreshing firefox, does not help). When installing via snap, there is no such thing, but it does not suit me for work, since there is a problem with profiles.

I would be very grateful for your help in solving this problem.

Firefox can't load any page, including about:config and about:preferences. about:support is working. All menus and surrounding UI is working too, but, for example, if I try to open Preferences page from menu - it will not open, even new tab isn't created.

If I start firefox with MOZ_DISABLE_CONTENT_SANDBOX=1 all works fine. Problem appeared after I accidentally used all of my laptop RAM with other app. Firefox didn't crashed, but after reopening this issue is began appearing.

I use Linux Mint 20, and apt-upgraded all packages (including firefox) right after this issue first appeared. I tried to: - restart browser (didn't work) - restart laptop (didn't work) - use different profile (didn't work) - use browser safe mode (didn't work) - clear caches (didn't work) - disable all extensions (didn't work) - use different versions: 75.0, 87.0, 82.0, freshly-compiled by myself (didn't work) - refreshing firefox (didn't work) - run firefox with MOZ_DISABLE_CONTENT_SANDBOX=1 (worked, but it's obviously unsafe and don't fix the root problem)

I found some issues and bugs that looks pretty similar to mine: https://support.mozilla.org/en-US/questions/1245935 https://support.mozilla.org/en-US/questions/1235332 https://support.mozilla.org/en-US/questions/1279656 https://bugzilla.mozilla.org/show_bug.cgi?id=1433065

Also, after closing firefox, it stays running in processes, and I can't open new window for 30 seconds or more after closing old window.

I think it's bug and problem is somewhere in firefox sources. Do you have any ideas, how can I fix this?

## When opening Firefox, it closes immediately

Hi!

My system:

• Win 10 64 Bit Desktop, completely up-to-date
• Two windows user accounts: one admin account and one standard user account
• using Windows defender / firewall only (NO third party virus scanner / firewall)
• Firefox 87.0

The last day, Firefox worked without noticeable problems. Nothing special happened. However, on the next morning, the problems appeared all of a sudden on the windows standard user account (The windows admin account is NOT affected by the problem):

When clicking the Firefox icon, the Firefox window appears for a split second and then disappears. In Task Manager one can see the firefox.exe processes appearing and disappearing again. It seems that firefox closes itself or is closed by anything else right after startup.

There is no crash, no error message, no crash report. It is simply impossible to start firefox.exe, no matter in which way I try it:

1. Same problem when trying to start in private window mode or in safe mode.
2. Same problem when trying to start profile manager.
3. Same problem when trying to start firefox.exe from windows explorer.

I already tried all the standard solutions, but nothing helped:

1. Uninstall 64-Bit Firefox and reinstalled 64-Bit Firefox
2. Uninstall 64-Bit Firefox and reinstalled 32-Bit Firefox
3. I deleted all mozilla folders in all subfolders of %User%\AppData and also cleared any temporary files there (this should delete all user profile data and all extensions)
4. I did a complete virus/malware scan using ten different malware/virus scanners (MalwareBytes, Adwcleaner, TDSSKiller, MSERT, Sophos, F-Secure, Kaspersky, Bitdefender, Windows Defender, ESET), some of them started from external boot media (i.e. they worked without the need to start Windows). Nothing has been detected.
5. Disabling Windows Defender and Firewall as far as possible (meanwhile, I installed Bitdefender, so Windows Defender / Firewall are replaced)

I did a closer look using ProcessMonitor64, but I could not figure out any abnormalities (maybe you can give me hint what to look for?)

What I discovered:

1. Renaming firefox.exe to anything else (e.g. firefox1.exe) makes it work (but this is not a solution of the problem because Firefox updates will no longer work then)
2. The user of that PC starts Firefox by double clicking on the task bar icon. Usually, a simple click is sufficient. Could the problem be caused by a too slow double click (= interpreted as two single clicks) and a concurring start of two Firefox instances?

Any ideas?

Hi,

I had to delete all my profiles and completely reinstall Firefox because Firefox was not changing the color of previous websites to purple no matter what I tried. I thought I could delete the profiles and create a brand new one to start over fresh.

After reinstalling Firefox (latest version) I have run into a problem where under <about:addons> <Plugins> it shows a yellow box and an error saying "Widevine Content Decryption Module provided by Google Inc. will be installed shortly".

This message won't go away and Widevine will not be installed at all. I cannot browse and Netflix, Hulu, HBO Max etc.

I have tried unchecking and checking the <Play DRM-controlled content> under <about:preferences> which does not work.

I have also tried going to this (link)link and manually installing it but the webpage for my OS's .zip file won't load for me.

After installing the Native MathML extension (to get MathML typeset equations on the Wikipedia, as suggested on mediawiki.org), all equations set by MathJax/MathML turned to using STIX instead of Latin Modern. I'd like them to stick to Latin Modern instead.

The only possibly related setting I've found is font.name-list.serif.x-math in about:config, whose value is Latin Modern Math, STIX Two Math, […]. I tried to manually change the font family specification of some text to see if Firefox could use Latin Modern Math to begin with, but apparently it can't (see first screenshot attached), while it loads STIX allright (second screenshot). Latin Modern is not the first locally installed typeface I haven't been able to use, but it's the first one I have really tried to (I don't remember which one the other typeface was).

My Latin Modern font comes from TeX Live 2019 installed using the TUG installer, not Fedora's package manager. fc-list | grep -i "latin modern math" returns /usr/local/texlive/2019/texmf-dist/fonts/opentype/public/lm-math/latinmodern-math.otf: Latin Modern Math:style=Regular`. I'm running Firefox 87 on Fedora 33.

Firefox keeps going unresponsive after 10 to 30 minutes. I tried creating a new places thing. It didn't work, and oddly still let me restore my old session and kept my bookmarks, which it said I'd have to re-install. I'm only running two extensions, U-block and NoScript. It will go Unresponsive, remain so far minutes at a time, briefly return and then immediately go unresponsive again, just long enough for me to close a tab or shut down. Nothing I have done seems to fix this. I am on the latest Windows 10, Desktop, latest Firefox.
