When I visit the https://forum.members.fsf.org site (as a member, but if you
as a LibreJS dev are not a member, we can help you with that), then LibreJS
says that there is no JS found, but allows it all to run anyway. This doesn't
happen in private mode though. (It works there).

I tried a brand new browser profile, and that did cause the extension to work
again, so I refreshed my profile, copying over important data like browsing
history, etc, and installed LibreJS. JS was properly detected on the forum,
for a while, but then the issue quickly came back, possibly related to my
whitelisting all remaining JS, then removing the whitelist?

In the case of the forum, we have a hard coded reference to a weblabels page
for the site, then I'm pretty sure that one gets loaded as part of the theme
via some JS. I wonder if LibreJS gets confused about that?

In any case, I'm currently on Abrowser 102 on Trisquel 11, but was using
Firefox 91-esr on Debian. The issue persists on this browser.

If you need access to the forum for testing, let me know, and we can try to
arrange access for you.

Thanks, : )
Andrew
