like all the other reviews say, this extension USED TO BE the best. But at the end of 2021 they made it useless, now all it does is freeze up firefox and if you don't remove it fast enough it will freeze your entire computer. There are no fixes as of Jan 29, 2022. Uninstalling and reinstalling DOES NOT fix anything, uninstalling and reinstalling the native app will also DO NOTHING TO FIX IT, it will work for a day or two but then it will go right back to freezing everything. Uninstalling and reinstalling firefox will also not fix the issue. It's a real shame that they ruined this extension it worked great for years, but now it's completely worthless.
