Firefox recently sent out its monthly newsletter (Oct '25) with all sorts of options that can be enabled on Firefox. I'm a computer illiterate & foolishly chose some of the options -- don't remember which nor know how to discover them.
Now javascript is no longer enabled on my MacBook Air (macOs Big Sur 11.7.10). I cannot access my protonmail account and many many other sites.
I've gone cross-eyed accessing "fixes" that are labelled "only for advanced users" & am bright enough to not even try.
Is there a simple fix (short of wiping my computer -- with data going back 11 years) that even I can do?
If you have "fixing your firefox for Dummies" then please email me with a solution. [edited email from public community support forum]
