If they break some pages, just temporarily disable the extension, and then re-enable it.First I use uBlock Origin (+ Nano Defender) and HTTPS Everywhere, like you. These are standard addons that don't seem important, but are actually important. Then I use CanvasBlocker and Decentraleyes. They break a few pages, but bring something in terms of privacy. I also use a password manager, KeePassXC, which is open source and works great with my Firefox. That's all, you don't need any more.
