Hi, I've recently contacted OneTab about this issue, however then I noticed I have a similar issue with AdBlock. By clicking on the OneTab logo there is no effect and the AdBlock one says "the AdBlock menu had trouble loading" and the addon is not working at all. I have attempted in the meanwhile several possible ways to solve the issue but none sufficed. Restarting my computer, firefox (on and off safe mode), enabling/disabling the addons, and this method (https://www.ghacks.net/2020/09/23/how-to-fix-onetab-not-working-in-firefox/). Could this be an issue due to the 82.0.3? thanks for any help
