Firefox Community Forum

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!!

Hello,

When I go to update Firefox through the settings > general > firefox updates > check for updates, I am getting the error in the title. I can manually download the app installer and update to the most current version which is what I did for version 125.0.1, yesterday.

I have tried uninstalling and reinstalling firefox, installing the beta branch, refreshing firefox, running in troubleshooting mode, completely deleting all user firefox files, and I still get the error. No DNS resolver issues to the update server. No firewall issues. No network blocking (tested with other devices).

This issue started after March update to 124.0.1 and continues to current stable release 125.0.1.

This issue also seems to extend to checking for extension updates.

Below are browser logs for when i try to check for update or update extensions.

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!

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.

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?

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.

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 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 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

Quick background: I live in the US. I wiped my computer while traveling in the Netherlands. I installed Firefox while in the Netherlands. I quickly noticed that the default language was Dutch. No biggie, I looked around and "managed language" to English in the Firefox settings.

The problem is that Firefox is still stuck on Dutch mode. Even the spell checker is stuck. Internal messaging is stuck (e.g. the messages on the bottom of the page while loading a site). I just went to DuckDuckGo and it defaulted the page to Dutch.

I understand that I could reinstall Firefox while I am at home (US). But I think this is a bug. The browser should be able to switch languages in the settings, etc.

Let me know if I am doing it wrong.

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?

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.

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 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

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?

I'm trying to migrate to the newest version of Firefox on an old installation of Fedora. I've downloaded and unpacked the installation files but can't identify the installer. All I probably need is the name, as I know how to make it executable and run it once I know what file it is.

Can I download Firefox and save it to a flash-drive instead of installing it? The computer I need it on has a new install of Windows 7 with IE and it will not browse.
