Hi, Since three or four months, whenever I log into Outlook live, either on Mac or Windows PC, I get a security warning saying that the information will not be secure (Please see attachment.) When I log into the same account, from Edge for example, I do not get the warning popup. I really enjoy using Firefox and would love to continue but this case is worrying me a bit. Any idea to help? Thank you very much, Mathieu B.

The problem seems to have started after a browser update. Running up-to-date Windows 10. This issue does not occur when using Edge. Youtube videos are blank (spinning). Sometimes it results is a still frame, other times it spins forever. Many times, you can see a series of stills in the video as the time line is dragged from the beginning to the end of the video. A small number of videos will work, but I have not been able to predict which will work or why. A different Win 10 machine on the same network is fine. I have tried all of the solutions I could find searching on-line (clearing cache, cookies, reboot, restart, update browser software, etc, multiple times). Checked settings in windows, firefox and youtube looking for something. Any help would be appreciated. Have used Firefox for decades and I don't want to be forced to change browsers.

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.

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?

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?

I have a Windows 7 PC. IE no longer works. I would like to use Firefox to access the Internet. Firefox offers a version for download. I got it using my Windows 11 PC, however it fails saying that it can only be installed on Windows 10. Can this be fixed? I cannot access the Internet from my Windows 7 PC.

hi, I love supporting this independent browser - I know its not perfect but it does a great job of doing most things well.

However, and there is a big but. I can be in the middle of an investigation that requires sharing data to a new tab - on opening the tab I'm blocked from going further as Firefox needs to do an update! This is really infuriating. No update can be SO urgent that you stop me using the browser. This is the Microsoft mentality, and its wrong. Can you please investigate NOT forcing users to update their browser during session.

Matt.

Hello,

When I try to visit a specific journal site that requires authentication, the browser automatically redirects me to an authentication page that I have used before. This is very annoying because every time I click a link to the journal, I’m sent to the other portal and can’t access the article. I want to stress that I haven’t installed any add‑on that would cause this redirection. I think I did that myself manually but I have no idea how. I’ve already deleted the cookies for both sites, but nothing has changed. I hope that makes sense, it’s a bit difficult to explain.

I'm using firefox 147.0, on mac Tahoe 26.2.

Thanks for the help !

On my MacBook Pro laptop, when I minimize a Firefox tab I cannot access other apps on the laptop. I can see them, but they do not respond to a click on them until I unminimize a Firefox tab.

REPEATING IMAGES involving . Macbook Air M4 Tahoe 26.2

When sliding from the primary Mac screen to another on the same computer the Firefox image (and ONLY that image) is duplicated on each additional screen image loaded making the use of multiple screens virtually useless.
