Firefox doesn't render after I've installed 'onetab' extension

I've recently installed "OneTab" extension and right after this my firefox stopped rendering (meaning it shows in the doc as if it is running, but there is no application that can be found on the screen)

I've read articles about problems with extensions so I deleted the whole firefox folder in the "username/library/application support" as I couldn't find anything connected to the onetab extension.

I've also reinstalled firefox both from brew and by downloading from the official site of mozilla. Of course, I've restarted the system a couple of times.

Help will be appreciated. Thanks in advance.

My system is macOS Sonoma 14.2.1
