SUMMARY
Since one week I experience annoying issue with arrange of Firefox windows after Plasma restoring the session. Namely, every time I run Plasma session all of them are placed at left top corner., despite before I had  them at different positions. Please notice that is not the issue with gtk+ applications, because Thunderbird which is also restored, is placed at position what I left it in recent session. 
Worth to add I have two Activities, on first one is running 3 Firefox and on second only one (here  also Firefox is placed at top left corner). Second thing is, my all 4 restored Firefox have couple dozen of opened tabs (one over 100).


STEPS TO REPRODUCE
1. 
2. 
3. 

OBSERVED RESULT
Firefox windows are placed always at top left corner after Plasma session is restoring .

EXPECTED RESULT
Firefox windows should be placed in position what they were when I log out from the Plasma session.

I cannot reproduce this on different account, where I started 2 Firefox instances with couple tabs. I'm not sure where relies the problem that position and size of Firefox windows are not saved and restored correctly in my one account
Comment 2 Piotr Mierzwinski 2023-02-19 22:30:57 UTC 
I cannot reproduce this on newly installed Neon Unstable Edition (placed on HDD). Firefox windows are correctly placed like at moment of unlogin.
