Steps to reproduce:

When switching tabs or dragging them around sometimes it will hang the tab list and the address bar. There's no way to know when this is going to happen and I thought it was some extension making this but a few days ago I was on a different computer with a clean Firefox installed and this happened as well.
The video I upload is recorded in a computer with Linux Mint 5 (Debian Edition) and the one I replicated it was a Ubuntu 20.04 but I don't know if this happens in other OSs. This is something that has been happening a few versions ago for me.

For me the strangest part is that when switching to another window (which works fine), the unresponsive one updates it's content correctly but still isn't working correctly.
The only way to make the window with the same tabs work as expected again is to exit firefox (I do pkill firefox) and start again.

The Bugbug bot thinks this bug should belong to the 'Core::Widget: Gtk' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

Thanks for the report! This is bug 1796960.
