Firefox Support Forum

After a crash earlier today within my 32bit install of Firefox, I upgraded to the 64bit version. Since then I have not been able to play videos from sites that utilize DRM.

I have tried the following:

1. Check and Uncheck "Play DRM content"
2. Check for updates while in the addons related page.
3. Checked my hosts file which is blank
4. Stopped my AV and attempted to update as well as Enable/Disable Play DRM
5. Get a 404 when attempting to go to "redirector . gvt1 . com" site.

When I looked in my profile directory, I noted that both the "gmp-gmpopenh264" and "gmp-widevinecdm" directories are empty. I found and downloaded the most recent openh264 dll for windows 64bit. Firefox continues to say "OpenH264 Video Codec provided by Cisco Systems, Inc. will be installed shortly." I have not found the most recent wildevine version so I have not tried to update it manually.

Could there be something squirrelly with my user profile that needs to be rebuilt? (I can export the bookmarks, etc) The 32bit Firefox crashed with no messages while watching a live YouTube stream. I just installed over without uninstalling the previous version. I was afraid of losing my current settings. The crash caused my "previous session" to be lost.

Can I transfer my existing Firefox profile on the Windows 7 machine to a new installation on a new Win10Pro machine by copying the profile from the "AppData" location onto a pen drive, and then copying that into the comparable folder in the new machine.

I assume if I can I will then need to make the copied profile the default one using profile manager?

Hello

I got a new Asus Vivobook Core i9 16G Ram I did the basic Windows 11 installation for the Laptop and installed TotalAV.

After all Windows 11 updates passed, I wanted to install FireFox anf got this issue: Firefox cannot start correctly (0xc0000022) after version ..

I tried several time to close all Firefox task, uninstall, remove all files from existing profiles (local, roaming, etc...) so as all files under "Programs"". I made sure to get the latest code, but I always get back to this issue.

While opening FireFox, I immediatly get a Crashed Tab reported. Even the Settings are not opening in a Tab.

I even tried to use a older version. Same issue... Never the less I can Update the older version in "About FireFox".

After update I see 122 installed

I used FireFox for many years, and wanted to continue.. In the meantime I installed Opera

Any help is appreciated. Thank you in advance Laurent

Hi,

I am trying to find version 120 for Linux. I haven't been able to find specific versions on the website and it seems to make me go in circles. I need the full install and the rpm for 120. I appreciate any help.

Thanks, Mitchell

Firefox was lagging everywhere: scrolling, switching folders in bookmarks, switching windows, switching tabs, opening settings, scrolling in settings...just everywhere. So I tried downgrading to v. 113. After downgrading via the ling in settings it still showed v. 114. I uninstalled firefox entirely and downloaded the loader for v 112. I installed it and it went thru whole install process to the point of asking to close and start Firefox. It didn't start. When I clicked on the icon it gave me a prompt that it didn't point to anything and asked if I wanted to delete it. I looked in program files folder but didn't find a folder for Firefox or Mozilla. I installed the developer edition and it worked but I don't want dark dev ed. Please help!

Whenever I try to download a rar file, like a game from itch.io,0 it automatically fails and doesn't download even after retrying multiple times.

If I download a .PDF file (or anything else) Firefox asks where I want to save the file and I can change the name of the file. The file is then downloaded to my selected folder on my PC. BUT a copy of the file, with original name, is also stored in my C: downloads folder. How can I stop that? I know how I can change the default folder but I do not want any default download folder, I want to be asked "Where?", "Name?" and the ONLY copy of download goes to that location.

For context, I accidentally made my root D: folder into the downloads folder and during this time I was still able to download using firefox. But when I finally changed the folder to my default one, firefox stopped being able to download anything larger than 1gb files. I can still download small images but anything larger than that I can't download. Else, it would only just show "Failed" in the downloads bar.

I've tried: 1. Changing the download location

>Also tried reindicating my download location

2. Turned off dangerous downloads 3. Putting an exception to the sites I try download from 4. Clearing the downloads 5. Tried troubleshooting mode 6. Restarting my computer 7. Restarting Firefox

I can't download on firefox but the same files I can download on Chrome.

52.9.0esr is claimed to be the last version for XP. Unfortunately it is not quite true. It is for XP SP2 ONLY. Trying to install on SP3 ends with the message that SP2 is required. IMO the installer is simply too strict on demanding exact version of SP ! https://www.mozilla.org/en-US/firefox/52.9.0/system-requirements/

I went through the list of versions (thanks Mozilla that they all are still available!) and found that the last version I can install is... version... 12.0b6. https://www.mozilla.org/en-US/firefox/12.0/system-requirements/

And indeed I installed 12.0b6 successfully but I would like to install 52.9.

Firstly, I have looked around on here for a bit and have not found anything.

I uninstalled Firefox because it was needing to update for a very long time, giving me a pop up every time I would open the browser, but if I clicked on the update button, it would just take me to a page on Mozzila that showed nothing regarding updates - if you scrolled down you'd get a normal download button for the entire browser which I already had. On settings, it would tell me my browser is up to date. Websites would give me pop ups saying I need to update my browser.

So I uninstalled it. And now I can't reinstall it.

I have Windows 10. On the Microsoft store, I have Firefox, but the "install" button does nothing. This is typical for the Microsoft store for me. On the Mozilla website, I can't get past the initial download page, I click download and it takes me to an error that says "this site cannot be reached" (so, please, do not link me to https://www.mozilla.org/en-US/firefox/all/#product-desktop-release or https://www.mozilla.org/en-US/firefox/new/ both take me to the same error page). I have already turned off Windows Defender, and turned off my ad block.

All of the info I have found assumes I already have the installation files, but I cannot access those because of getting the error I described above. No idea where to go from here.

As the title says i have enabled always ask where to save files but when i try to download files it saves them in my Download files most of the times.I didnt have the problem yesterday. Can you please help.

Hi there!

I'm attempting to migrate my Firefox (106.0.3) profile from the Linux Mint V20.3 on one SSD to a new installation of Linux Mint V21 on a separate SSD. I'm using the information supplied on this page:

https://support.mozilla.org/en-US/kb/back-and-restore-information-firefox-profiles

Step 4, under Backing up your profile says: Right-click on your profile folder (e.g. xxxxxxxx.default), and select Copy.

This folder, qspfoqtl.default, contains 1 file, named times.json, the contents of which are:

{ "created": 1618792039414, "firstUse": null }

Clearly, not my Firefox profile.

There is, however, a folder named nnob5aww.default-release that contains a bunch of directories and files (505.4MB) with names like bookmarkbackups, browser-extension-data... storage, weave.

Is this documentation incorrect as of this release of Firefox? And, should I be using the nnob5aww.default-release folder as the profile? I'm a little confused. (Most often, I'm a lot confused.) Any help would be appreciated.

Thanks in advance,

- Ralph

I'm having a problem with Win 11 that will likely require that I reinstall the OS. I decided to move most of the data in my User folder by right clicking and changing the drive from "C:" to "E:" in the Locations tab. Firefox was closed as a I did this, it worked fine, and then I restarted the PC. Upon opening Firefox none of the extensions are working and I'm not sure what to do.

Over the years I have accumulated important links in my Firefox Bookmarks bar and passwords file and it would be a disaster if for some reason my hard drive got compromised and I could no longer access them. Is there any way to copy the data to another set-up, independent of my laptop, from where the data could be retrieved in a usable form for display on another laptop or PC? Thanks.

Where can I get Firefox 52.9.0? There was a list of old versions here but now I can't find it. I found https://download2.portableapps.com/portableapps/FirefoxPortableLegacy52/FirefoxPortableLegacy52_52.9.0_English.paf.exe I really did not want the portable version but avast considers it a threat so it may not be genuine.

I have just downloaded firefox from chrome and cannot install it. I have tried the usually uninstall reinstall and restarting my computer but cannot fix it. I have had this issue with other browsers in the past eg opera and brave but gave up on them, however, I really want to switch to firefox so would appreciate your help. For some reason it seems chrome is the only browser I can even open on my laptop (windows 11). Do you know a fix?

I have been using Firefox 56.0.2 on Windows 7 for years safely. Until yesterday. We had one of those mini powerouts, that caused problems.

My hard drive is failing and Firefox will no longer fully load, it tries bless it, but some FF files must be in the damaged sectors of the hard drive. It then locks the system. Using Chrome works fine. But some logins/passwords/bookmarks had to be changed very recently and are not stored in the chrome browser yet. I hate chrome so use FF as the main browser.

I'm thinking that if I can install a fresh copy of FF 56.0.2 in a separate folder, a separate 2nd copy of FF, and then copy yesterday mornings backed up FF profile (before the crash) I could at least copy over all the bookmarks etc to Chrome so I can have my logins etc back.

This mornings backup failed to backup some FF files, all others were fine. Firefox worked fine yesterday but failed to launch this morning.

Please help save my sanity. I know I have to move to W 10, but cannot on this computer.

I reinstalled Firefox, now 119.0.1 64bit on our Mac M2 now OS13.6 via download-reinstall in the owner account on our shared Mac. The "Firefox is being updated by another instance" line in About Firefox still has not gone away after closing and restarting Firefox.

Presuming this will disrupt future updates, I seek help.

Background: Last spring, I upgraded from a 2016 Mac on OS10.15 (which still appears on my Mozilla account) to this M2 OS12 now 13.6. I had previously set Firefox to prompt me for updates because they could disrupt my work on the old Mac. It worked fine up to 118 point something. Up to my ears recently in urgent other stuff, I deferred the prompt for 119. Then, frazzled, I just closed several 119 prompts. Today, after helping my wife use her account on the M2, I found in my Dock's active apps area an icon for something like Updater something-or-other. After a while, I swiped it away.
