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!!

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.

Is it possible to install Firefox (or at least the profiles) onto an external SSD (i.e., not the C: drive)? If so, how?

Note: this is not about migration/backup/recovery of profiles. Nor is it about where files are downloaded by default.

Windows 11 is consuming nearly all of the C: drive. I badly need to get Firefox (and later Thunderbird) onto my E: drive. I further note that the installer gives no options whatsoever as to the destination drive.

Most of the help I've found on the web is clearly outdated.

Thanks. jt

I am not sure when exactly problem started but for few months I have problem with automatic update of firefox. It properly detects update and downloads it but when I click to restart browser and apply update (this should close browser and display update install bar) nothing happens - browser simply closes. When I launch it again and go into "about firefox" again I see spinning circle next to "installing update". Of course this update never installs. When I close it for 2nd time and go into "about firefox" it goes back to "update ready to install, click to restart" - and again, when I click it browser simply closes without restarting and installing update. I tried removing my profile, using safe mode, disabling antivirus. Issue seems to be related to firefox itself. I also tried removing mozilla maintenance service but it did not help. Does anyone have any idea what could be causing this? For now only way for me to update firefox is manually download full installer from website and then it installs latest version without any problems - until next month comes and I have to update it again.

I have been trying to solve this for a few days now. I tried to watch Netflix when it said, "Firefox is installing components needed to play the audio or video on this page. Please try again later."

I found out this was due to Widevine not being installed AT ALL on my browser for some reason. The plugins manager has been saying that it will "be installed shortly" for a week now. I already tried toggling DRM off and on multiple times. I already tried using troubleshooting mode. I already checked GMP preferences to make sure nothing relating to Widevine was set to 'false'. I already tried turning off my antivirus long enough to try everything again and still nothing has changed. I do not have any VPNs running either. I am attaching a screenshot of what the browser console shows when I toggle DRM off and on again and try to run Netflix. I am also attaching what the gmp toggles say. Please help me figure out what is wrong!

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.

firefox setup 127.0.2.exe offline installer fails with message about "extraction failed" and popup "file is corrupt".

Windows explorer shows file properties and a signature for mozilla.

Is there a way to manually unpack the .exe? Someplace that issues are logged with more data (which file is corrupt?) There is a progress bar that flashes by part way, then a popup window with the file corrupt message.

(Trying to update to hopefully get rid of some crashes.)

Is there a hash for that .exe I could check?

Hi there.

This is my first post so bare with me.  :-)

We are deploying the 32-bit version of the Firefox Browser to 4 700 clients and the 64-bit version to only 8 clients; all clients on a 64-bit Windows 10 environment. We will migrate to Windows 11 22H2 this year. The manager for the 8 clients says he wants the 64-bits version just because it's...64-bits. No other reason.

I've read that the 64-bit version can not handle Java, Media Players like VLC and mayby some other plugins. Is that still so?

What is the main reason TODAY for using 64-bit Firefox Browser instead of 32-bit, except for the use of 4 GB+ RAM?

I wish to install and use the Firefox browser on my old 64bit Windows 7 laptop.

I believe the last v115 will be the last Windows 7 compatible version of Firefox, if this is correct where can I find this or the correct version of Firefox to download and install on my Windows 7 laptop?

The Firefox website only seems to provide v119 now.

Thanks, Graham

With the release of the new ESR version, version 115.x.x, the install creates a shortcut in the Windows Start Menu called "Firefox Private Browsing". How can the creation of this shortcut be prevented during install?

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.

Hi, new updates on Version 98.0.1 quite a hassle for me. It auto-download all my files even when I just want to view. Is there any other way to disable this feature? I opened Setting>Download but there is no disable button or checkbox for that. Please help me. Thank you in advance.

I have downloaded and installed Mozilla Firefox on a new computer through the Edge browser both from the Mozilla site and through the Microsoft store. The installation downloads and installs as it should. Firefox has been selected as the default browser and everything appears as it should. When I open Firefox and type in an address, nothing populates. No site will open on the screen. When I open settings in Firefox, nothing opens. When I open history, it shows that I have been to the sites that I have loaded even though they haven't shown on the browser. I have completely uninstalled Firefox and reinstalled it with the same result. I have downloaded Opera browser and it installs correctly, I have downloaded and installed Firefox from Opera and had the same result. Any ideas?

Thanks, John

At some point every night, my Firefox (and only Firefox) reverts to version 111 from the latest version. This happens on 2 different Windows 11 machines.

I can only get Firefox to run again by running from command prompt with "-allow-downgrade" option and then updating again.

I usually don't notice until I launch Firefox the following morning and it gives me a message that the profile was created with an older version and to exit or create a new profile.

I've had Firefox open and then it reverts and it gives me a XULRunner error about the profile being used by an older version.

I don't have any special backup or restore software running and the physical files in my Firefox folder in c:\program files\mozilla firefox are being physically pushed to a prior version dated 3/21/2023.

On both machines, I've completely uninstalled and reinstalled and it's good for a day and then reverts.

No log entries for the reversion can be found. It's just back to a prior version.

I've never come across anything like this before and have scanned for any malware or other issue, but haven't found anything.

Hello!

I'm writing because I cant seem to import my old profile using this [tutorial]. I have followed it thoroughly, and every time I open firefox its still the same default page that you get when u first download the browser.

I have migrated from old MacPro to new Mac Studio. Firefox ESR version 115.9 has migrated with it. I've downloaded the latest Firefox but it operates independently of the ESR version. How do I ensure new version has all log in, contacts and history?

Automatic update on my Windows 10 desktop of the the new update 127.0.1 resulted in a version of Firefox that worked more or less for some web sites but was unable to reach others.'

How do I uninstall the Firefox icon from the taskbar? The standard article on the Firefox Support website is `How to pin and unpin Firefox from the taskbar on Windows 10 and Windows 11', but it seems to be out of date. It says to right-click on the icon and click on `Unpin from taskbar', but there is no such item in the right-click menu any more.

I know that it became difficult to unpin the Firefox icon about a year ago. I got a new PC recently and installed Firefox, but I could not remove the icon. Then realised that I should have done this during installation, by using 'Custom installation' and unticking the 'Icon on taskbar' option. I searched the web for clues and found none, so I uninstalled and reinstalled, which was a nuisance.

Some months later, I have just installed the new version 110.0.1, but I forgot to use 'Custom install', with the result that the icon is back on the taskbar. Again I have searched the web, and again no success. I tried reinstalling V110.0.1 on top, using 'custom install' this time --- I could switch off the 'Icon on taskbar', but the icon is still there.

I don't want to uninstall-reinstall this time because I have now configured Firefox as I want it, so that would waste a lot of time --- and I will probably forget again sometime in the future.

I am sure that Firefox has not done this deliberately, because they are always so much on the user's side.

QUESTION: How do I unpin the Firefox icon from the taskbar without uninstalling? I have an idea that there is a registry hack that will achieve this.
