Hi,

Looking at my Firefox 147.0.1 settings for macOS 26.2 (Apple M1), I'm trying to adjust two settings:

-- I'd like to remove Languages -> English (GB) (its existence has odd side effects, like triggering United Airlines to offer fares in Pounds Sterling, and I'd prefer to just have English (US))

-- I'd like to disable Play Audio and Video for about:welcome (in regular and private windows)

I can see no way to accomplish this currently -- why?

Thanks.

I moved and my moving company had my computer soundly packed in a box. After 2 months I have hooked it up. Tried to open my Firefox and the message stated the file is corrupt. I've opened a new Firefox account. Can I get my old account back or can I get my old information into my new account?

I recently went to settings to make sure my default browser on my Windows 11 device was Foxfire. I think I also saw an option to move all tabs over from other browsers, but instead of adding these to my current ones on foxfire, I think it just replace all of the ones I had as they are not in my history any longer either. I went to the 3 lines, to settings, to general, made sure all was checked properly, but it did not help bring the others back!!! help

I've tried messing with hardware acceleration, resetting the zoom to 100, it seems when i get the zoom as low as possible it tries to fall back into place, i can't find any fix on this, i like this browser but i cant watch anything like this

I have the latest version of Firefox. I still keep getting the prompts to download the latest version. When I go to system info, it shows I have the latest version it is asking me to download. When I do a manual search for the latest version, it always says it failed to search for the latest download.

Mozilla made an update of my Firefox installation on my Win11 laptop. all my password disappeared as well as my history and bookmarks.

I have now a virgin installation and is starting from scratch.

Now I get this error message: "This profile was last used with a newer version of this application. Please create a new profile." I deleted met shortcut and I opened Firefox by using Windows search. Now I see 4 profiles! I think I do not need to create a new profile. Maybe delete 3 of them ? What to do ? And, how?

Hi, When I want to open and see most of sites, this extension show me the pop up and message:

Environment - OS: Omarchy - File manager: Nautilus (running as --gapplication-service) - Desktop portals: xdg-desktop-portal + xdg-desktop-portal-hyprland (+ gtk fallback) Firefox: latest stable from Arch repositories

Observations Only one Firefox process is running (pgrep -a firefox). Only one Nautilus process is running, but it receives two open requests, resulting in two windows. The issue does not occur in Chromium/Chrome, which opens only one window. Running xdg-open <file> manually opens one Nautilus window.

Portal logs show GTK being chosen as last-resort fallback, but system-wide XDG configuration appears correct.

Question

Is this a known Wayland/portal bug in Firefox? Are there recommended debugging flags or patches to trace the duplicate launch request?

Hello everyone,

I’m experiencing ongoing problems with Firefox and hope to get some help or clarification here.

Main issue: I’m unable to sign in to my Outlook / Microsoft email account using Firefox. The login page does not load correctly, or the sign-in simply fails (Error 400). When I use another browser (for example Microsoft Edge), the login works without any issues.

System information:

Operating System: Windows 10 IoT Enterprise 2021 (LTSC, supported until 2032)

Firefox version: 147.0.3 (64-Bit)

Additional problems: Besides the Outlook login issue, Firefox has recently become more problematic during normal daily use:

Text selection with the mouse often does not work correctly

Clicking and dragging to highlight text is unreliable or stops working

Pages sometimes feel unresponsive, (ChatGPT)

Overall, the browser feels less stable than older Versions on Windows 10 22H2

These issues seem to be getting more frequent over time and occur on multiple websites, not just Outlook.

I switched my system to Windows 10 IoT Enterprise 2021 (LTSC, supported until 2032) in the hope of improved performance and stability.

What I have already tried:

Clearing cache and cookies

Disabling all add-ons/extensions

Testing in Private Browsing mode

Restarting Firefox

Unfortunately, none of these steps resolved the problems permanently.

My questions:

Is Firefox fully supported on Windows 10 IoT Enterprise 2021 / LTSC for the long term (until 2032)?

Are there known issues with Microsoft / Outlook sign-in specifically in Firefox?

Are there known stability issues (text selection, mouse interaction, page responsiveness) in recent Firefox versions?

What settings or troubleshooting steps are recommended to improve stability?

Thank you very much for your time and support.

Best regards, Marco Klecker

Desktop Firefox 147.0.3 (64-bit) When I open Facebook, pictures of accounts are continually blinking (not flickering). This problem is new and appeared just after last Firfeox update.

Recent (Windows?) update signed me out of Firefox. Logged in again, but bookmarks aren't showing up. Bookmarks are marked for sync-ing, and I did try sync-ing twice. Maybe I have to sign back in on the original device?

I have configured Firefox to use a proxy, and I stored the credentials in the password manager. However, every time I open Firefox, it asks me to enter the credentials again.

How can I store the proxy credentials persistently?

Within the Applications section of my settings, I have it set to open content type of crcc with an application. However when I try now after the latest Firefox update, it opens a new blank tab instead of just launching the application. The URL of the blank page is just "crcc://the_URL_of_the_launching_site?params=dG9rZW49ZWJlN2IyY2FmMTM3YmQxODM3ODZhZDU1NWY2Zjc0ZDNiMWE5ZWIyMSZ2ZXJzaW9uPTEwLjMuNTEzMjEuMjUxMjAmdHVyblBhcmFtcz0lMjJzdHVuJTNBc3R1bi5sLmdvb2dsZS5jb20lM0ExOTMwMiUyMiUyQyUyMnN0dW4lM0ExOC4xOTYuMTA3LjIwOCUzQTM0NzglMjIlMkMlMjJ0dXJuJTNBMTguMTk2LjEwNy4yMDgrJTVCMTc3MDk5NzE1MSU3Q2JsR2hXNDQ3STV5NVl1ViUyQlZ0WXBtMmdKUkpjJTNEJTVEJTIyJTJDJTIyc3R1biUzQTE4LjIwOC4yMy40NSUzQTM0NzglMjIlMkMlMjJ0dXJuJTNBMTguMjA4LjIzLjQ1KyU1QjE3NzA5OTcxNTElN0NibEdoVzQ0N0k1eTVZdVYlMkJWdFlwbTJnSlJKYyUzRCU1RCUyMg==" I tried the standard clearing cache, private window with no help. Anyone else notice this and is there a work around. Of note, after about 5 minutes it does eventually open the application.

Hi, I use Firefox as a primary browser on multiple PCs, so want it to remember a couple of addresses & payment methods for easy daily useage. However, I also access one business domain & when using that website only, I don't want Firefox to offer/remember/anything when it comes to addresses (which will be customer addresses) or payment details (again, for customers). Other autofill, like suggestions for some form fields would ideally still work.

Is there are way to make one domain exempt from address & payment saving/retrieval?

Thanks.

My local network is 10.10.10.x and I can't log into my NAS, web server or another computer on the local network... Internet access is fine. Happens on Wi-Fi or Ethernet.

If I access the same web address using Safari or Chrome it works just fine and it used to work before the software update to the 147 build.

So what switch/setting got kicked over during the upgrade that I have to turn off?

These kind of issues really make me mad at the Firefox Dev team... and I'm a very long time user.
