Firefox has been running incredibly slow. I currently only have this window open, but if I open my task manger it shows 10 Firefox windows running. If I right click and end task, it will end the task, but shortly there after a new one will pop up. 1 of the is running in efficiency mode. I assume this is what is slowing down performance, but I do not know how to fix.

Seems I've noticed an issue with playing of YouTube videos the last few days. It seems that either the video(s) is slower to load and/or is slower to play. While it's not terribly slower in human time it's slower than normal in computer time. I'm not having this problem in Chrome. Cookies and cache are cleaned multiple times a day. So, I'm a little stumped as to why I'm having this issue. Any comments would be appreciated. Thanks

when attempting to move Firefox bookmarks to my new computer, I click import data within the Firefox page. The computer asks me to select the file. I have no idea where the bookmarks reside and cannot find a file. What is the procedure to get this done?

Firefox Containers > Manage Containers > Remove [container]; message (modal, I think it's called?) pops up to say I have a tab open and do I want to proceed? I to up to the container icon upper-right, search for [container], click to open that page, then CTRL+W to close it. Then I try to Remove [container] again; fails. That container is still in the list, and still popping up a note that a tab is open in that container (no, I closed it).

I really like the Containers feature, AND it could use some improvement.

Unrelated, I'm open to help with proofreading; feel free to ask, or point me to a git where I could contribute. I'm not happy about the apparent erosion of privacy in Firefox, but it sure beats Google, Microsoft, Apple, etc.

Today was the second time in two weeks I have lost every open tab in Firefox. Previous to this, this problem has not occurred in at least 5 years. What is going on? To utilize data from multiple sites takes a long time to relocate sites and this is becoming unacceptable. Firefox updates are better than this. Thank you for your help.

When i drag a tab to reorder it, it always just opens in a new window. I also can't move a tab back into another window with other tabs. I'm on linux mint running on wayland

When trying to do a search for a video in YouTube Studio, the search seems to freeze. Doing a similar search in Microsoft Edge works OK. This problem started happening several months ago. I've tried clearing the cache for YouTube pages.

More frequently than I care to admit, I seem to close FF instances which I don't want to close (such as my connection to Whatsapp). I then miss important replies or questions. Of course I can reach out to 'History' and try to find the closed Tab or Window... But that takes time.

I'd suggest adding/removing a 'protection' flag to a tab (eg. on right-clicking), so that, on trying to close the tab, or close the window containing the tab, I get a warning...

I created an account on an old PC, in the account it is visible as kos-work-note, now I am on a new kos-ltop, and there is no data at all in the browser, why is that?

W 11 May, 2025 update really made my computer unable to go online in any way and I had to restore. But FFox updates to have made it impossible to communicate. My phone has trouble s too. So, how do we make stick telephone permissions for, say: G Voice page https://voice.google.com/u/0/calls now? Thank you

I don't know where to write this. Hello everyone, Firefox has an auto-fill feature for cards. I wanted to enter all my cards. I enter my card, and it comes to the expiration date. The card says 10/37, but in Firefox the maximum is 35. Alfa Bank Russia has started issuing cards that are valid for 12 years, I don't know if it's to save money or not. What should I do, wait 2 years? Or has a similar question already been asked here and will it be fixed soon?
