I-Firefox Isithangami Sokwesekwa

Just downloaded 113.02 Firefox. Frame around firefox windows and tabs loses Min/Max, "X" exit button and full screen buttons. Coloration of the frame also changes from solid to opaque and back without any input from me. Does seem to vary based on memory usage. High usage appears to cause these symptoms but can't be sure. Controls do not reappear. Double-clicking the frame makes them reappear only momentarily. Uses Windows 7 Pro OS.

I will be moving all of my data to a new laptop and want to know if I need to have both my personal Firefox profile and the "default-release" profile backed up. The "default" one is over 3GB and has over 20k files in it, and my personal one is only 113 MB with 1300 files — and my thumb drive needs all the extra space it can get. (Why would the "default-release" profile be so much larger than my personal one?)

The old laptop runs on Windows and the new one will have the Linux OS. Will that make a difference in using a backed up Firefox profile? I mean, will the data still work in the new OS?

Im using Firefox desktop version 113 with win 7 Browser will not save logins or passwords either saved by me manually or by importing from chrome.

Below you will see the screen from my settings after saving. Strangely, I do get the prompt to save them. See other image below.

I do not want to use sync. I only want firefox to store this locally as the earlier versions did without any issues.

Thanks
