Today using Firefox 93.0 on my Windows 10 home computer I opened the browser to my Audible library on Audible.com and selected a book to download. The browser download window opened with the book file name but the extension wasn't .AAX but had been changed to .MP4. This did not happen when I used Microsoft Edge nor did this happen on my Windows 10 laptop which was still running Firefox 92.0. Once Firefox upgraded to 93.0 on my laptop I now get the same problem as I get on my home computer.

Audible technical support looked into the problem and found that this change wasn't caused by their servers.

I have discovered that if I change the file extension from MP4 to AAX I can load the audible book into iTunes and sync it over to my iPhone which is able to play the file as an audible book. This indicates to me that the actual AAX file was not converted to MP4. For some reason only the file extension was changed.

I wasn't able to find any setting in the Firefox browser that corrected this problem.

Hello.

I have two profiles, for separating work and personal tabs/bookmarks/etc. I wanted to update Firefox from 95.0 to 95.0.1 but in both profiles I saw "Firefox is being updated by another instance" in the About Firefox dialog when both were running. So I closed one of them and the other offered me the usual button to update immediately. I did it, restarted that Firefox instance/profile, which restarted normally, but now the second one does not open. Instead, I get the error transcribed above in the subject (see attached screenshot).

So my question is: please, how do I regain access to my second profile without losing that profile's data?

On Win11, after I installed firefox on a custom location(like D:\Firefox), Firefox can not open any page, even its option page. If installing at the default location(C:\program files\), everything works fine. But custom location works On Win10. Firefox version: 95.0.1, x64

I reinstalled Firefox and now need to import passwords from file where they were exported before reinstall. This article https://support.mozilla.org/en-US/kb/import-login-data-file explains how to import passwords from file, but this option is missing. The only option available is Import from another browser.

From here https://bugzilla.mozilla.org/show_bug.cgi?id=1702336 it looks like the feature was disabled 9 months ago. It is not clear what is the workaround in interim and what is the current state of resolution. For example, how do I use passwords CSV file to load into Microsoft Edge or Chrome and then import this data from that browser back to FireFox?

Yesterday I received an update fot Firefox, previously FF 95.01. Now, in FF95.02 the Firefox start page is lost, and add-on` s don`t work anymore or are simply vanished. I want FF95.01 back, or a resonable update, like 96.

I'm trying to move my profile from an "old" laptop to a "new" laptop. I've copied the profile and put the files under a new profile which I generated with the profile manager on the "new" laptop. When I try to start firefox on the "new" laptop I get the Error Message "... your using old version ... this might corrupt your current data ... please create new profile" When I create a new profile (see above) I'm in a circle (catch 22 ;-))) When I click "close" no firefox opens.

"old" laptop runs Version 94.0.1 "new" laptop runs Version 93.0

Cannot get rented/paid Youtube or Netflix video to run. Message "! Sorry, there was an error licensing this video" pops up onYoutube screen every time when hitting play button. "Free" Youtube videos work just fine, paid content gets this message. Have firefox-9.5.0.2.ta.bz2, use Linux updated software. Followed all previous suggested Support, cannot seem to find fixes that included DRM, Safemode switch, etc. Thanks for previous help, still stuck... anymore ideas appreciated. Also, difference between running "normal and beta", please explain, and how to know "differences?"

I moved my Firefox installation to a new machine. After creating a new profile and moving all my old files Firefox has opened with all of my old info and is operating properly.

But when I tried to change the location of the cache file to the correct drive on my new machine the about:config file does not save the new entry. When Firefox is closed and re-opened the new entry has been reset to the old location.

I've tried deleting the browser.cache.disk.parent_directory entry in about:config but when the program is re-opened the entry returns with the old directory shown.

Any advise would be appreciated.

Hello, since migrating from Chrome to Firefox, I have used the Import Wizard to successfully transfer over my bookmarks and history, but I just can't seem to get my logins/passwords over. The wizard finishes saying that it successfully imported saved logins and passwords, but nothing shows up in the password manager. I am running Windows 10 64bit and Firefox is up to date. Anybody have any suggestions?

Thanks

I downloaded several files and I can see them when I click on the little arrow, but when I look for them in my computer downloaded file , they aren't there. I go back up to the little arrow and it shows the file was downloaded, but it's not in my computer . So when I went back up to the little arrow and right clicked on it to open --it worked, the file opened, but it never showed up on my computer. The next day I tried to find the file in my computer but no success. I went to Firefox drop down and under downloads the file showed up, but I couldn't do anything with it. So now I can't find it on my computer and it doesn't work when I use it from Firefox's drop down selection. I have downloaded several other files with no problem. Here is the file. https://www.benefits.va.gov/HOMELOANS/documents/docs/VA_Buyers_Guide.pdf HELP Ron

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".
