Diễn đàn hỗ trợ Firefox

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.

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?

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?

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?

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

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?

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.

lost all bookmarks and can not add them back. tried the restarting, importing from Google, etc. Sadly I am off of Firefox after more than 20 years using it. Fortunately Google works fine for me, but I miss Firfox.

I do not like the current Firefox. I am 'trying' to get my firefox the way it was in the previous session yesterday.

Monday 19th.

For some reason I click a tab this evening and I lost everything. Now it is a lavender color (ugg) and all my information, tabs, everything is gone.

Please help.
