I moved to just using uBlock + noscript + containers. EFF people don't know how to audit things. It's better to use as few extensions as possible + put services you paid for into a Firefkx container to segregate the browser rather than try these half measures.

Also Firefox now builds in functionality similar to HTTPS everywhere:

Code needs to be reviewed to be safe, so minimize the code in your browser to reduce both fingerprintability and possible exploits.
