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".

Why is the 78.0.1 download for MacOS called "Firefox 78.0.1esr.dmg" and not "Firefox 78.0.1.dmg"?

The download dialogue (image attached) that appeared said that it wanted to download "Firefox 78.0.1esr.dmg". The "esr" in the filename surprised me, as I'm not on any ESR release train. Why is it named that and not "Firefox 78.0.1.dmg", similar to its predecessors?

What setting will stop the constant notice "Download the latest version of Firefox." I don't want 20 notices per day. It's like having a child in the backseat "are we there yet?" "are we there yet?" "are we there yet?" How many times do I have to click the "Dismiss" button before this stupid software understands that I do not want updates? I've noticed that this is a common complaint. Stop the bullying by making people choose automatic updates. Many times things get messed up on my computer with updates and it is not worth the aggravation. Candace M.

Yesterday when I installed the 96.0 update it has forced my background color into a dark grey and ignores the background color setting. I would like to know if there is a setting, add on or update that can return this to normal. The theme I am using has not been updated in 2 years so I am fairly sure the update has caused this.

I had this problem 2 years ago and somebody helped me fix it as follows:

(1) In a new tab, type or paste about:config in the address bar and press Enter/Return. (2) In the search box above the list, type or paste URLB and pause while the list is filtered (3) Double-click the browser.urlbar.autocomplete.enabled preference to switch the value from true to false

HOWEVER --- I don't seem to have browser.urlbar.autocomplete.enabled in my new version 74.0. What happened to it? Does it have a new name now?

Note that I tried in Options / Preferences / Search

    I unchecked "Show search suggestions in location bar results

In Options / Preferences / Privacy

   I uncheck each of the boxes in the Location Bar section (History, Bookmarks, Open tabs).

A few days ago Firefox automatically updated and destroyed all my logins and passwords and a huge amount beside. Yes, there was blurb about how to find them which involved a file which did not exist on my system and the whole was not comprehensible.

I did ask for help but got nothing

Somehow, the next day my system had gone back to the earlier setup. Now Firefox wants me to update AGAIN!

Given my experience how can I trust Firefox not to destroy my data?

I use multiple Firefox profiles. Normally, Profile Manager always appears at launch.

But lately, if I launch Firefox while a profile is already open, it just opens a new window in the current profile. The only way I can get Profile Manager is by typing firefox.exe --profilemanager.

For the record, I don't have this option enabled: Use the selected profile without asking at startup.

I've had this happen twice now. Getting a new PC and wanting to transfer my bookmarks from old to new. I have had bookmarks on the old computer arranged in order of priority from left to right on my bookmarks bar. Did the export to create a HTML file and saved it so that I could import to new Firefox browser on new computer. So far so good. However, when setting up new browser and importing my bookmarks from the HTML file, it just creates a single folder on the new browser's bookmarks bar, instead of spreading my bookmarks out on the new bookmarks bar as it should. The bookmarks in the imported folder are still in the order I want, but to get them as individual items on the bookmarks bar, it seems I'd have to drag and drop them one by one to the new bookmarks bar. Solution please?

Have got most of it fixed except I can't get the BOOKMARK "BAR" to display [see pic attached].

If I select "Bookmark" on the top bar, it opens the bookmark window but I want it where it has been for over a decade, between HISTORY AND TOOLS.

I downloaded the current rel 86. My first FIREFOX copy was ~2004/2005 ver 1.0.

The installation of Nightly caused major problems in Firefox. (Windows 10 PC) I want BOTH Nightly and Firefox on my computer; however my Firefox profile became corrupted in the process. Things like: the Bookmarks not appearing despite all the settings for them being correct; Firefox crashing when importing bookmarks. Fed up, I decided I wanted a completely new installation of Firefox. I could use my sync to my Firefox account to get most of what I needed back easily... I thought. I don't want to detail every step, they are too many. The important part, I think, is this. Installing Firefox, I need for it to create a new profile. Beause the old one had NUMEROUS corruptions, I got rid of it, thinking that Firefox can create a new profile when installing the software from scratch. But guess what? It will not do that. THE PROBLEM is that Nightly and Firefox share the same Roaming/Profiles folder, which means that the .ini files contain references to BOTH profiles in a single file. Profiles.ini contains both. Installs.ini contains references to both. If I delete - or try to alter the contents of - either .ini file, then Nightly loses its profile as well. I have restored those two files to where Nightly now starts up normally, thank god. But there is NOTHING I can do so far to get the new installation of Firefox to start up without trying to find the now missing profile which was corrputed to the point that it was more trouble than it was worth. It used to be possible to install Firefox and make whatever fixes were necessary before starting up the browser. Now it is not; it starts up automatically, or not at all. WHY is the setup designed this way? Really large error on the part of Mozilla developers to put the profiles info and installs info into the same file, so that upon uninstalling Firefox, you must either find the old corrupt profile again, or start from scratch with BOTH Nightly and Firefox. We waste SO MANY HOURS trying to work around the careless / thoughtless things that developers do! Please can someone help me? For now I have Nightly, but it looks like I will never have Firefox again after using it and its ancestors for 25 years. Thanks in advance!

So yesterday I got a new computer and downloaded Firefox to be my default browser. It worked fine the first few hours -- I was able to log into my account, set up my extensions, and use the browser as intended. A few hours in, though, it completely crashed on me. I am unable to go to new websites, refresh a page, open bookmarks, log in to my Firefox account, or even open settings; the home screen also doesn't load when I open a new tab. Literally the only thing I can do is freeze the Bookmarks Toolbar and customize the Toolbar. I tried closing and reopening, refreshing/resetting the browser, restarting my computer, going into Troubleshoot mode, deleting and redownloading the application, but nothing is working. I have no trouble with Firefox on my previous computer or my phone, and Edge is working fine on this computer. I don't know what to do anymore. Any help would be much appreciated.
