no window rules enabled

Comment 2 Lua 2021-05-04 21:35:25 UTC

This happens in the latest FF release (88) and in 89 (beta).

Comment 3 David Edmundson 2021-05-04 21:55:16 UTC

X or wayland?

Comment 4 Lua 2021-05-04 22:26:53 UTC

X, I forgot to add this.

Comment 5 David Edmundson 2021-05-05 21:34:12 UTC

I don't see where kwin would be involved in this.

Please test your firefox setup under openbox and confirm what happens.

bug doesn't happen

I couldn't use Openbox, SDDM always got frozen, so I tried another environment: the bug doesn't happen in Budgie.

Comment 7 Lua 2021-05-07 07:53:04 UTC

This also happens in Wayland.

Comment 8 twinshadows404 2021-05-17 11:08:46 UTC

I can confirm this under 88 and 90.0a1.

Operating System: openSUSE Tumbleweed 20210514
KDE Plasma Version: 5.21.90
KDE Frameworks Version: 5.82.0
Qt Version: 5.15.2
Kernel Version: 5.12.3-1-default (64-bit)

Do note that the new window has the maximum size, but it isn't maximized.
Changing status for inspection as per comment 6

Comment 9 David Edmundson 2023-09-06 10:38:30 UTC

This bug was reported against an outdated version of KWin. We have made many changes since the. 
If the issue persists in newer versions can you reopen the bug report updating the version number.

Comment 10 Nate Graham 2023-09-06 13:51:33 UTC

Can confirm, but maybe this is a Firefox bug?
