@ -midnight,

Another thing is, that could be just because of that corrupted file, to uninstall your firefox,
and reinstall the browser with a complete fresh install. That may finally cure it.

I personally think you will be overtly very, very happy with Brave, as it comes closest to your personal likings and views.
Also the lay-out of the browser is gorgeous and a very one-way of using it.

It impressed me a lot both in the laptop version as the Android one. I like iridium a lot, but have Brave as well on that same machine and my android device and on both the computer and mobile phone of my dear spouse.
