The tab group suggestion feature is unavailable for me, even though I am on Firefox 145.0 (64-Bit on Windows 11 Pro 25H2). I tried using guides like [one from mozilla] https://www.askvg.com/enable-or-disable-new-ai-powered-smart-tab-groups-in-firefox/ this external about:config editing guide.

The latter does changes to the about:config. A screenshot of my settings, my config, and my Add-ons is attached.

I do not know what is wrong.

Firefox's new version was installed but after downloading and opening, when it opened, NONE of my tabs opened. I tried 6 times to no avail. I need my tabs. How do I fix this?

Enter (paste) the URL into the Firefox address bar → hit Enter (paste and go) → open in a new tab every time. I want this to open in the same tab. Firefox version 145.0

I've been using the firefox broswer on a mac for the last couple years and I installed the duckduckgo search feature into firefox today, also firefox updated today when i turned my computer on so I'm not sure which one is the culprit but I lost all of my bookmarks and saved form data. Is there a way I can get my bookmarks back? I wasn't using an account or signed in ever but would that info be saved on my computer?

When I approved the installation of the latest Foxfire update this morning, I got the message "Couldn't load XPCOM." Another popup message included "error status 0xc000012f." Firefox does not work. Thanks, Joan Karrie

This is where you describe the issue in detail.

Explain what’s happening (e.g., “Videos keep freezing after 10 seconds”).

Mention when it started and what you already tried.

Include your Firefox version (you can find it under Menu → Help → About Firefox).

I recently added the primary password (master passwrod) for my firefox browser from the settings.

Normally it locks the browser functionality until the password is correctly entered, but one thing I noticed recently was that the hyperlinks/webpage links from 3rd party app (discord/pdf readers/etc) opens the website regardless of this password input. I can use the page to browse the internet, although the password still works for locking other things like firefox's built-in password manager.

Is this intended mechanism for a "locked" browser?

How do I get rid of new, but stupid vertical sidebar? I do NOT NEED OR WANT even MORE junk taking up the screen space. Is Mozilla part of Microsoft now? How do I get rid of that junk?

I search but did not find any list of environment variables supported by Firefox. Is there such an official list, perhaps groupped by Firefox version, published somewhere?

I changed my password.......still not letting me in....so I changed emails....I'm confused.....I want to know did my new pc accept my change of passwords from my older computer?

I recently experienced [not previously] in trying to print a received e-mail using the "print" item. When I clicked on the "print" word I received the following error

https://mail.yahoo.com/print/message/AFe0zTKlUhih9Gu_uzKg3tJ-XbE?appName=NOVATION_APP sent back an error.

Error code: 403 Forbidden

   Check to make sure you’ve typed the website address correctly.

Please advise how/where I may change a setting to avoid this error

I get n error report when I try and access the seagate login page. This was not a problem a couple of days ago. The error report says 'You have not selected this website for SSO'.

I cannot find any help to resolve this problem and it is slightly odd that it was an accepted site previously.

Many thanks for your help Paul

I want to change my Firefox password. Roboform has all my login info. When I opened the change password dialog box I was asked for my current password & Roboform filled it but the dialog box says it's wrong. How do I locate my Firefox password?
