My Firefox sometimes freezes in the evenings when using AOL Mail and Facebook. I put this down to my old and slow PC. But I now have a brand new PC working on Windows 11 and all seemed fine, but it happened again this evening. I then logged into Facebook using MS Edge and it was working fine.

I just read a PC World article concerning extensions containing malware. AdBlock was listed and I've been using the extension for some time. Are you aware of this issue? Is the extension available viz Firefox setting/extensions in question. Should I remove it?

After running cc cleaner and even that i de select the book mark and side setting the Firefox Bookmars and history is non functional . i did create a new profile yesterday biut today i have the same Issue. I uninstalled CC CLeaner but i want to restore my Bookmarks system i need help with that. the explanation here are not really helpful

With the latest update to Firefox, 147.0.1, our test suites run with the extension, Selenium IDE, has errors, "Failed:n.createEvent(...).initKeyEvent is not a function". I am running the latest version of Selenium IDE. Installing the previous version of FF has no errors. What is the solution?

All of a sudden today yahoo will not load I am able to load fine with edge I keep trying and sometimes it will partially load..I've used firefox for years along with yahoo wth zero issues..please help I have cleared browsing history etc to no avil

When I start Firefox on Windows it does not open all the Windows it had last time even though that option is selected in settings. It seems random on which Windows open.

Then I start one Window at a time and restore my tabs from bookmarks. Once I have done that I have all the Windows in the order I want, with the tabs I want.

Then for no apparent reason some of the Windows disappear and/or the Windows change order. This is very frustrating.

How do I get Firefox to always open the Windows in the correct order and keep them displayed in that order?

So, after using firefox in the background to browse websites or watch videos I checked my memory usage in firefox with about:memory -> Measure and saw that youtube was consuming a decent amount >2GB (checked the main url when clicking the youtube src, it was the video on that sole tab i was watching and nothing else playing youtube in the bg) so i closed that tab, waited a bit and re-measured but then see that the memory usage for youtube rose about 200MB... and the website for youtube is that same url for the tab that i just closed (when checking the src in the results for Measure). I've been revisiting the about:memory page, reloaded it and re-Measured and youtube is STILL THERE. Even now, 10 minutes later i still see youtube there, with none of my tabs running youtube.

If i close firefox entirely and re-open my tabs then it'll very likely fix it but this has to be a major issue no? I shouldn't have to close the entire browser program just to fix a website visit, which is youtube of all websites.

As of this moment, firefox, with 8 tabs open, is consuming 4,452.99MB (~4.5GB) where 2.5GB is youtube for that page i closed.

I don't know if sharing memory reports from the about:memory page give my cookies away or leave me open to a similar vulnerability so I won't share it unless a dev or similar asks for it but for now, I've included an image showing all the tabs i have open on firefox, 2 windows.

  Firefox is currently my "default" browser.  I am running the most current updated Firefox browser.  I am using a desktop iMac with OS of Tahoe 26.1     
  It appears since the latest few updates (on Firefox) over the last week or so, I can no longer log in to my online banking.  I am able to enter my username and password (I'm using the 1Password app on this desktop and my iOS).  After entering my username and password, the progress wheel just spins and spins and nothing further happens.  The screen just sits there and does not progress to the next webpage allowing entry to my banking.  I know that it is a problem with the Firefox browser.   When I log in to my online banking using Chrome, I have no issues, it logs right in.  
  What is going on?   Please advise.  I'm thinking about ditching Firefox and going with Chrome or Safari.

Thanks for your assistance Dennis Ontario, Canada

Where are my shortcut tiles? I used CCleaner and they all disappeared and I can't get them back even though I make sure they were on and have 2 rows selected and restarted my computer since. This happened last week and still no sign of them. See pic for reference.

Hello Firefox Support Team,

I’m writing to report an ongoing issue I’ve been experiencing with Firefox over the past few months.

Within the last four months, Firefox has logged me out of every account I was signed into on three separate occasions. Each time this happens, all saved sessions are cleared and I have to sign back into every service again manually.

I haven’t intentionally cleared cookies, site data, or browsing history, and I’m not using private browsing when this occurs. This behavior is disruptive and I’m concerned there may be a settings issue, bug, or conflict causing Firefox to remove my sign-in data unexpectedly.

Could you please advise what might be causing this and what steps I can take to prevent it from happening again? I’m happy to provide additional details such as my operating system, Firefox version, or troubleshooting steps already attempted if needed.

Thank you for your time and support.

Best regards, Luka

As usual on forums, none of the subject choices exactly fit my situation/problem, so I apologize for any unintended misdirection.

How do I uninstall Privacy Badger. It's been disabled, but not uninstalled. Please be specific as to keystrokes, screens, boxes, location of item. Many instructions tend to overuse computer jargon or common industry synonyms used daily within their sphere, which a laymen cannot easily translate, and often raise more questions than they answer. Installed on my Firefox browser. Thank you in advance.

I started my computer bookmarks and password were gone. I can't find them in profiles or I don't know where to find them in profiles. I need this stuff obviously. It takes me forever to reset everything. What if anything can I do?

Firefox installed a new version and my stuff has disappeared. I don't recognize the window at all. I have tried the "restore sessions" but I'm told it can't happen. I need my stuff back.
