I treat extensions like they're all capable of privileged local code execution. My selection is very vetted and very small.

The only extensions I have installed are dark reader and ublock origin. Would be nice if I could disable auto updating for them somehow and run local pinned versions...

Get the source code and manually pack your own unsigned web-ext’s.

Add-ons Manager -> (click the add-on in question) -> change "Allow automatic updates" to "Off"

(for firefox/derivatives anyways...)

Same here, uBlock Origin and EFF's Privacy Badger are the only extensions I trust enough to install.

Ditto, plus 1pass / BitWarden.
