What are your favorite add-ons for Firefox?

The ones I am unable to use a browser without:

• Sidebery
• Darkreader
• Bitwarden
• uBlock origin
• uMatrix (even if it won't get any more updates)
• Firefox Multi account containers (although I probably can just do this with Sidebery)

Nice to haves:

• Tabby
• Don't Fuck With Paste (this is really nice when login pages try to prevent password manager for “Security” reasons)
• Augmented Steam
• ProtonDB for Steam
• Imagus
• HTTPS everywhere (because websites still to this day can't set a proper redirect)
• Facebook container
• LanguageTool (semi open-source alternative to Grammarly)
• Invidious (this redirects YouTube links to invidious instance selector)(There are like 4 different ones, all not updated in 2–4 years, I am thinking of learning enough coding to support this)
• Tabliss (this is a nice new tab where I can add reminders of what I am supposed to be doing instead of what I am doing)
• Custom Scrollbars
• User-Agent Switcher and Manager

I used to have plugins for reddit (like RES and old reddit redirect), but won't need them anymore.
