Breaks login.microsoftonline.com in Firefox android app

Because of this add-on, Firefox takes at least 15 seconds to open on Android. I removed it and got rid of it. Adguard is much better.

I have been trying to add ublock origin, to my Roku TV . For weeks so I can watch Youtube without any adds. I have even tried to add it to my wifi router, but nothing works. If anyone can tell me (In plain English) how to get it installed. I would greatly appreciate it ! Thanks

THANKS !!!
