Real sandboxing, if not possible, give the users the possibility to activate admin-installed extension, and not the possibility to install every shit which comes with a "I am free" or "I am sexy" tag.

the admin-installed extensions would be installed for every user
you can restrict yourself doing so by just only use packed extensions

yum search mozilla | grep -i extension

Yes it is.

security and usability are always a tradeoff

Not always, and if, sometimes security has to win.

frankly, a lot of people hate my security-first attitude but in case of browser extensions i just don't want run to every machine for every extension update and hand out the admin-password is a no-go

hence the topic *is* nonsense

No, it is not

well, depending on the extension (noscript) as example there are very often updates - you are in danger to train users to always and everywhere anter their root-password or skip updates which may be security relevant

Mozilla is solving most of the issues by just only install signed extensions - let's wait how many people switch to the developer version without that restriction because 1 or 2 of their favorite extensions are only available directly from the developer
