tabs become unselectable and can't be dragged out of the main window
This started happening a few days ago.
I tried to drag a tab out of the main window to put it in its own window on my other monitor, but the tab just became unselectable, and if i scrolled in the tab bar, the tab icon and text would remain locked in place in the display while the other tabs moved behind it.
The main Firefox window also lost the minimize, restore, and close buttons. The only way to make the tabs work was to close Firefox and relaunch it.
I noticed this happened only after any app in the OS went full screen, be it a steam game, or another Firefox window, or a VLC window, or anything else that I did that made an app full screen in any of my monitors.
I am using Ubuntu 24.04 with KDE Plasma 5.27.12. Kernel is 6.14.0-29. Display server is Wayland.
Initially I thought this could be a problem with the snap version of Firefox, so now I've installed the deb package, but the problem remains. Firefox is the only app which presents a problem of any kind when any window goes full screen.
Here's a video showing what the problem looks like, in case my description was not clear. The ghostly tab in this video is the chess.com home page and you can see it as the third tab from the top right of the video, and it remains in that position as i scroll the other tabs, completely unselectable with the mouse.

Any idea of what could be causing this issue to appear?
Thank you!

What happens with a tarball from Mozilla? Try downloading Firefox from Mozilla. Download, unzip, and run firefox-bin from the folder and see if you have the same issue. https://www.mozilla.org/en-US/firefox/all/#product-desktop-release
Also see what happens with your OS via a live usb stick.

aha! i tried the tarball version, and i excecuted it, without logging in or anything. I also launched the deb i installed, then i launched a game in full screen, and, on the installed version, it happened, as expected, but on the tarball version, tabs were still free to move and be dragged out of the main window. I thought it was curious that it didn't happen on that one, so I thought maybe it was related to how many tabs i have open, so I opened a bunch of tabs on the tarball version, and it happened there too, ghostly unselectable tabs when trying to drag them out of the window or move them in the same window.
next i'm going to try the live usb bit and see what happens
Interesting... So the chess site is the only tab not moving or all the tabs don't move? How many tabs is a whole bunch? ;-)) Also see what happens in X11. You could also try another OS via live usb. ;-))

Nope, any tab, be it chess.com or any other website.
Enough tabs to enable the scroll thingy(no idea what that feature is called)
I'll test on X11 because now it's gotten worse. it feels like the thing is alive! fresh reboot, opened firefox, no fullscreen anything, and i dragged a tab to the other monitor, and it was fine. i dragged another, and it was also fine, but when i went to move one of those tabs back to the main window on the other monitor, it happened. tab locked, unselectable and ghostly. And another new thing is that the entire search bar dies on the window where a tab goes ghostly, nothing is clickable anymore, unlike before where the other tabs in the window worked fine and the search bar worked fine, as did the refresh, and back, and forward buttons.
You know, after fully ditching windows 2 weeks ago and doing a fresh ubuntu install, it's been so troublesome that trying out a new OS is something i've been considering myself. Or hell, another browser, but I already completely ditched chrome when their anti-adblock update hit me, so I'd like to stick to Firefox for now.
Thank you!

Looks like it's time to get off the ubuntu bandwagon.
it sadly won't be to openSUSE. I use waveforms on a regular basis, and they seem to only be developing it for debian based distros now, after the qt6 implementation of it failed on fedora. they didn't bother to try for openSUSE.
in other news, the problem isn't present with X11 on Ubuntu, and to make things even more confusing, when i switched back to wayland, the problem has yet to present itself again. This feels like dealing with a whimsical creature and not with a deterministic machine
Did you try your os from a live usb stick? Is there a reason you're not on KDE6? Same issue under a different user account?
I just gave up and switched to X11. i tried from a live usb, but i couldn't replicate the issue in the 30-ish minutes i tested it for. Didn't try with a different user account. it didn't occur to me to try that. It looks like I'm the only one experiencing this issue, so switching to X11 until next big update, where I will switch back to wayland and see if the issue persists.
I'm not on KDE6 because I'm using the KDE version that's on the ubuntu repos for 24.04, installed with "sudo apt install kde-plasma-desktop", and KDE 5 was what got installed from that command
