No Script - Yes, I run both UBO and NoScript, they have slightly different use cases
Dark Reader
FireFox Multi-Account Containers
Redirector - Great for automagically changing links
KeePassXC-Browser - For password manager integration
Rested - For monkeying with REST APIs
User-Agent Switcher and Manager - Why yes, I am the browser you are looking for
Video DownloadHelper - Because sometimes, you need stuff available offline
In terms of actually recommending extensions to others. I’d recommend most of the above, excepting NoScript. If you are using UBO, then the use case for NoScript is a very narrow one where you want selective whitelisting of javascript while visiting a site. UBO’s blacklisting approach works for most cases and UBO’s whitelisting feature is lacking the granularity of NoScript.
