FireFox is buggy, being unable to resize and is covering my start menu / task bar.

Just did a fresh Firefox install. Windows 10 64 Bit, version 1511 about to do the 1803 update. I do have all the NET frameworks (not sure what Firefox dependencies are, but I've never had issues). My video drivers are up to date. Windows is up to date (with the exception of Update 1803).

I don't know why this is happening. I've tried to uninstall Firefox, I've deleted all files from %appdata% (and rebooted after), I don't have any themes/addons enabled or installed. It is doing this stock, right away from installation.

Having weird bugs with Firefox in general:

Firstly being unable to drag it to resize it. Being unable to maximize it by touching the edges of the screen. Maximizing via top right corner button makes it cover the entire screen, task bar as well. There's a weird graphical thing going on in the top left corner.

Here's a video of what's going on: https://streamable.com/4npfr

Can someone help please?

Okay so apparently this has been going on for nearly a year. If you look at the post accidentally shown in my video, it'll reveal the user is going through the same thing I'm going through.

I switched the theme from 'default' to 'light' and it's working fine.

That's a good workaround, but I wonder why the Default theme, which may be trying to use a more Windows native appearance, is having those problems?!
