1) If I don't see an Https://"'at the beginning of your Mozilla url in the top of my address line I don't proceed further.

2) My cell phone isn't working presently so when you offer an option to confirm who I am by sending a number code to my cell phone number I'm unable to use that option it to confirm who I am. How 'bout coming up with an additional alternative or two for confirming?

Many thanks!

I’ve been using Firefox regularly and overall the experience has been positive, but I’ve noticed a pattern during longer browsing sessions that I’m trying to understand better. When multiple tabs are opened and I switch between them frequently over time, Firefox sometimes becomes less responsive. Pages may take longer to load, scrolling feels delayed, and opening previously loaded tabs isn’t as smooth as it was at the start of the session.

What makes this a bit confusing is that system resources don’t appear to spike significantly, and the slowdown seems gradual rather than immediate. Restarting the browser usually restores normal performance, which makes me wonder if this is related to session handling, memory cleanup, or how background tabs are managed over time.

I’m not necessarily looking for a quick fix, but rather trying to understand whether this behavior is expected and if there are recommended settings or habits that help maintain performance during longer sessions. If others have noticed similar behavior or have insights into how Firefox manages extended tab usage, I’d really appreciate learning from your experience.

I lost my entire browser (bookmarks, extensions, accounts) by opening firefox twice. Whilst firefox was opening (very slowly due to my wifi) i opened it again, thinking it may have crashed, next time i opened it my entire browser was gone. How can i recover my data?

Hi,

Using the most recent version of Firefox that will run on my old Mac's 10.12.6. All of a sudden, when I follow a link to a Linkedin job opening announcement, the contents of the entire page opens in a 3"X3" frame in the upper lefthand corner of the page, with the old bottom and right side scrollbars and everything. To lower right of the empty white page there's a Linkedin toolbar about 5" long. (See attached screen cap.)

Impossible to read or use the page as-is, and it can't be dragged larger. At a loss to explain; to the best of my knowledge I haven't changed any Firefox or Linkedin preferences.

Haven't seen frames in about 20 years. I'm remembering why I hated them.

Anyone?

A website I have accessed many times before now redirects me to an italian site. Is this because of the beta translation? I'd like to be able to go to the real site. mecaforpeace.org

I continue to receive (LATELY) 403 error. WHY??? NEVER had this issue until lately. ONLY in FIREFOX!! Image attached.

Would like you to work with me to get this resolved.

Facebook videos in Firefox stop playing when clicking the Windows 11 Start button or opening Solitaire (after recent update)

This issue has just started after a Windows 11 update and restart. It has never happened before. I usually watch Facebook Reels while playing Solitaire at the same time — yes, I know, I don’t have a life.

This morning, after the update and restart, I opened Facebook and started watching a Reel as normal. As soon as I clicked the Windows Start button to open the list of programs, the video stopped. I then selected Solitaire, which opened to the taskbar. I restarted the video, clicked Solitaire to open the game fully, and the video stopped again. As soon as I minimize Solitaire, the video resumes playing.

I’ve tried all the suggestions I could find via Google, but nothing has worked so far. Note that this only affects videos playing directly on Facebook — videos playing in the Windows Media Player Legacy video player itself are not affected.

Any help would be greatly appreciated… and yes, as mentioned, I clearly don’t have a life 😅 Link to video showing what happens when I select Solitaire in the Taskbar. https://drive.google.com/file/d/1oKLIl3I4f9lfTZvbU-9pJ1gMbOU7h0zm/view?usp=sharing

Regards everyone.

More info... I run two monitors and it seem if I click on whatever I have open in the second monitor the FB video stops. So something has changed after I turned my computer on this morning and updated Windows. I even did a System Restore to a setting two days before this new update and nothing changed still have the problem.

I can run Firefox once after starting the computer. If I close Firefox, I cannot run it again. Any attempt to start says there is an instance of Firefox running so it cannot start. I did some research and for that running the following yielded some indication of a problem that I cannot seem to solve.

>taskkill /F /IM firefox.exe ERROR: The process "firefox.exe" with PID 10220 could not be terminated. Reason: There is no running instance of the task.

Something appears to have left this PID so that the computer thinks it is running when it appears that it isn't there.

Please advise. [edited email from community support forum]

Firefox has been crashing regularly for a full day now. I have one profile with multiple extensions, and a fresh profile that is meant to test firefox without any. With this new, "clean-slate" profile with none of my extensions installed, I still get repeated crashes. It is getting in the way of my ability to work- it happens even in Troubleshoot mode, even though I could not confirm any hardware issues prior to this.

Will I need to delete the extenstion-filled profile entirely before going forward? Is there an update I need to install, or anything else I should do myself? Should I provide a list of my extensions?

Attached is the Report ID of my latest crash- hopefully it will help.

Thank you!

I cannot open the msn site , on my Win11 desktop using Firefox.

https://www.msn.com/en-us/weather

which is not down and opens in the Google browser. What can I check , this has happened off and on but is now broken this week. The msn.com site does open , but clicking on the weather tab still fails.
