This is going to be long sorry. A lot has transpired

My son was using 78.15esr. I upgraded it to 91.3esr. After the upgrade the browser worked; tabs loaded, surfing was fine, could go into settings and about:config was fine.

He went to watch something on Netflix. Netflix complained his browser was not supported and he needed to upgrade to the latest version - which at the time was 91.3esr.

In frustration he installed Chrome. When he tried to run it he was told software restrictions were in place. I had not set any restrictions, and I checked secpol.msc and there were definitely no path rules defined. If restrictions can be set in group policy I had not set them because I am unaware of them.

So he installed Microsoft Edge, which installed VC runtime for 2013 and 2015-2019 for both x64 and x86.

At that point Firefox no longer loads tabs at all. About:<anything> doesn't work. Settings doesn't work. You can't go to safe mode (more on that later), and when closing the browser two processes remain taking about 60 seconds to end.

I did have the group policy templates for Firefox installed. When I upgraded to FF 91 I installed the latest templates.

A couple of times when I started FF it complained about vcruntime140 was missing. But just running FF again worked without doing anything else.

So I reverted to 78.15; I uninstalled v91.3esr. I deleted his profiles.ini and profiles folder and then copied them back from a back up. I removed any registry settings, and copied back the v78 ADML files. I then installed v78.15esr with internet disconnected. Did not run FF after install. Went into group policy editor and turned off telemetry and auto updates then re-enabled internet

Run FF and same issue. tabs not loading. Pages not loading. I can click on a menu and I can type into navbar and search bar but there is no response. I checked internet was working.

I deleted the %LOCALAPPDATA% cache folders. I flushed the DNS cache. None of this worked.

So I uninstalled FF again, deleted the profile folders and ini. Disconnected from Internet. Deleted any registry settings, and removed the group policy templates. Then installed 78.15 from scratch and let it create a new profile.

Same darn problem. It seems to me that installing chrome and/or edge has done something nasty, but I have no idea what. I say that because before he did that he could surf the web, but Netflix just said his browser ver was outdated.

I tried contacting netflix on chat but they were worse than useless.

So I uninstalled again and removed everything. Connected the internet and installed FF again and let it update automatically. Same problem.

I've left him with edge but I need to fix FF.

I even uninstalled the VCLibs, Chrome and Edge. These did not fix the problem.

I tried safe mode but when firefox restarts there are two processes that take 60+ seconds to end so FF sits there saying "restarting...". When those processes finally end Firefox does not restart.

Checked for viruses; nothing found. Rebooted PC several times.

So at this point in time; FF will run but will not load the 3 tabs; Facebook, Netflix and youtube. They stay blank. Settings is not accessable, nor is addon's or logins and passwords. Typing anything on the search bar does nothing Typing anything in the address bar does noting Trying about:config or about:profile or any other about's does nothing. When closing FF two processes take 60+ seconds to end.

If I go back to him and tell him I need to reinstall Windows he will go absolutely nuts.

What also worries me is that Netflix said that the most recent esr browser version was not supported and that he should update to a later version.

And what is even more troubling is I updated his girlfriends PC at the same time and hers works perfectly. This scares the hell out of me because I then expect responses like "Your sons problem is not a firefox problem".

I use debian and firefox-esr.

I have problem right now!

I used firefox version 105.0.1 for short times, then firefox transformed my profile to new version profile, so now I can't back to 102-esr version again, I have this message:

`Your Firefox profile cannot be loaded. It may be missing or inaccessible.`

So i try this command to fix problem

firefox-esr -allow-downgrade

or

firefox-esr --allow-downgrade

But still can't downgrade, So I have to ask could I downgrade? else I have to wait for new esr version?

What's the next firefox-esr version? or release date?

I had two Firefox windows open, one private and one not, and a lot of tabs open on both, and while I was browsing the internet on the non-private tab, suddenly both of them close. I reopen Firefox (or it reopens itself, I don't quite remember) and it shows me a message telling me about how I can save articles on pocket to read them later instead of keeping lots of tabs open. I restore my session, and most (but, bizarrely, not all) of my tabs come back, but then, I try to log into gmail, and I never get past the stage where it asks me my email adress, I keep re-entering my email and clicking on the next button and it just loads the same page again, and when I try to log into crunchyroll it brings me to a page that just keeps loading and stays black without ever being truly loaded, and when I try to log into twitter everything stays black too except with a twitter logo in the center. I can still go to some other sites on Firefox, and I can still go to twitter, gmail, youtube and crunchyroll on Google Chrome, but twitter, gmail, YouTube and Crunchyroll don't seem to work on FireFox and I don't understand why!

Hey Mozilla!

I'm a big fan of your product, and I use it on my Windows 10x64 PC and my Note10+ Android 12 smartphone.

Since your last update, there is a problem (on the PC mozillla browser): when a click a link to download a file, automaticly is open a new window that OPEN the file. Before the last update, when I was click-ing the link, I remember that the browser was open a small window and promt me to OPEN or to SAVE the file. Now, that function is missing. (I have checked different web sites, including whatsapp for desktop, the problem is persisting).

I haven't changed any settings, the box is checked for "Always ask you where to save files".

Thank you!

Hi,

TL:DR, Firefox 108 refuses to update to Version 109.

Firefox refused to update to 109, repeatedly said 108 was the latest version. I was sick of websites breaking so I decided to reinstall Firefox, and the website worked perfectly fine on the reinstalled one, since that app is on 109.

Unfortunately, it caused a whole host of problems since I have two Firefoxes on my laptop. When I finally got rid of the older Firefox, it worked fine…

…until I restarted my laptop. Upon launching Firefox, it crashed my laptop and when it rebooted, the Firefox reverted back to version 108 with 109 nowhere to be found.

How can I get Update 109 on my laptop? Thanks in advance.

Hi, I have spent hours this morning trying to diagnose a problem with Firefox Update 115. It is Unstable and I can't Stream Music from Youtube or even Amazon Music. Web pages from sites I use everyday are out of order when displaying text as well. It's a real mess. Now, here's the kicker, I haven't been able to stream my music from both aforementioned websites, but get this, if I use the Incognito Browser, Music streams No Problem. Seems like you guys broke something in the main FF browser. I have spent hours trying to debug this and have concluded that your most recent Update has broken streaming links. I can't rollback the Update and that is even more frustrating. Please Fix This. BTW, your Help Pages really stink. Sorry, but they offer no help when the problem is clearly FF.

Hi!

When Firefox 96.0 rolled out on my machine, I was surprised to see my old Firefox Quantum theme default to dark. I did not enjoy this new behavior, so I tried to downgrade to 95.0.2. After installing it, Firefox told me it couldn't load the user profile, as it was used on a newer version of Firefox.

I have no idea where exactly I read this, but some website contained an instruction to erase compatibility.ini and that would allow me to use the profile on older versions. Tried that and it actually worked. I did notice that, when Firefox tried to update, it would say it failed. I was hoping that, once I find a solution to the forced dark mode and I update Firefox, the problem would go away.

Fast forward a few weeks, I found AutoConfig and browser.theme.toolbar-theme option in about:config. So I updated Firefox manually and applied AutoConfig and my original problem was gone.

Fast forward more weeks, there is another update for Firefox. And Firefox was still unable to automatically update. So I tried reconstructing compatibility.ini, which I did fully. But Firefox still won't update.

At this point, it's been like 3 months with a crippled user profile and I must say I'm tired of updating Firefox manually.

Is there any way I can fix this profile? If not, what exactly should I copy over so all my preferences, cookies, addons and themes get carried over to a new one?

I checked the previous solutions in the forum, but they did not work for me. (Windows 11) I changed in system> general > download , applications > the app to open that file type and it works, but besides this Firefox keeps saving the files in the default download folder.

I tried also about:config browser.download.improvements_to_download_panel to false. browser.download.start_downloads_in_tmp_dir change to true No change - still saving copies.

I'm currently using a Windows 10 desktop computer most of the time, but will need to use a Windows 11 laptop for research travel several times over the next several months.

Will it be possible to copy my profile from Win 10 to the Win 11 computer, use the Win 11 computer for a few weeks, and then copy the profile back to the Win 10 computer?

Or is there something different about Firefox working with Win 10 or Win 11 that would keep this from working for me?

(BTW: Using Sync would probably not be feasible.)

Advice will be much appreciated!

I just installed Firefox on a new Windows 11 desktop computer. I ported my profiles over and it appears everything came over EXCEPT: - Themes aren't working. I've tried switching them and they still don't display. The menu bar is black w/white letters; the toolbar is gray with white icons/letters. - My extension icons are there...sort of. If I hover over them I can see the tool tip but the icon doesn't appear on the toolbar which is light gray in color. I can live without the themes if I have to. Not so much the invisible extension icons. Any suggestions as to how I can get them to appear as they do on my Windows 10 desktop? Screen cap below. Cursor is hovered over the Undo Close Tab extension icon but where's the icon? Any suggestions as to how to troubleshoot this will be appreciated!!
