Hi, I'm currently running Firefox on Fedora Linux 35 with Gnome 41 on a dual display setup, with a vertical one on the left (1920*1080) and a horizontal one on the right (2560*1440). I always open Firefox windows on the 2560*1440 monitor.

After closing the window, Firefox seems to remember the height of last session but not the width. Or more specifically, the width is always restricted to 1080, which is exactly the width of the secondary display, if the width on closing is greater than that. I checked the xulstore.json file in the configuration folder it always shows "width":"1080", which confirmed my speculation.

Is there a way that makes Firefox's new opening window with exactly the same width as when it was closed ignoring the second display's resolution?

Interesting... I use Nightly and can't recall ever having this issue. I'm updating and restarting daily and Firefox never has an issue on my external monitor. Are you using the Distro version of Firefox? Try it from Mozilla and see if you have the same issue. https://www.mozilla.org/en-US/firefox/all/#product-desktop-release

It actually solved the issue! I think Fedora does have a separate Version of Firefox. Thanks!

Good to hear. If you look at the help and about Firefox from the distro version, it should show for the distro. see screenshot
