Diễn đàn hỗ trợ Firefox

I have recently had a Computer Crash and have set up a new Computer. However, I cannot find a way to synchronize my old Bookmarks. Part of the Problem probably is that when the Syncing was originally set up, I was using a different User Name [e-Mail Address] to that I am using now. I have been using Firefox since 2006; and have an old Sync Key dating from some time in 2014; but cannot find a way to enter it into the current Firefox Settings. How do I recover my Bookmarks?

There's also no way to add an exception? Just completely broken at the moment. I have to disable OCSP stapling to get it to work at all, which is less then ideal.

Currently using 125.0.3 (64-bit). I checked for newer versions of firefox and it's not saying anything. Chrome and Edge work fine. Encountered this on an android tablet with firefox, and went to desktop and hit the same thing.

I choose a new theme. After a while, I close Firefox. When I start Firefox again, my chosen theme appears briefly, then the default theme replaces it. Why? FYI: it doesn't happen with just one theme.

The file icons on by desktop were always the standard color but now the are blue and white why did this happen. I know I can change each one back individually but how can I change them in mass.

Hello i work on fesco bill website and Experiencing trouble with my site's responsiveness on Firefox. Seeking advice and solutions from the community. Your assistance is greatly appreciated!

Hi, first the last update tried a few times over some days to install. Never got confirmation that it has been installed successfully. When I go to "About Firefox" I'm getting the information that I'm using the latest version.

Now I have problems, mainly when using facebook (especially when I try to play games through facebook) that Firefox uses enormous amounts of CPU and Memory. This does not happen all the time but at least in 70% of tries. I attached 2 screenshots

If this happens I'm not able to close Firefox the normal way but have to kill the process in the task manager.

Any quick help would be appreciated. I would also like to know if I'm the only one experiencing this or if it's a common problem.
