If you're not using Tor browser, why not?
@hache >or really why it would be necessary for my purposes...
That depends entirely on your purposes! The more people there are using Tor, generally, the stronger the network is.
You can use tor to anonymize your web traffic, to send and receive files anonymously (using onionshare), and to host websites on your local machine without having to deal with DNS or security certs. It makes it harder for companies (and others!) to track you, when used correctly.
Then, a big rust change came and broke firefox, firefox-esr and thunderbird. The fixes seems easy but it wasn't possible to apply it on tor-browser because it was already outdated compared to firefox-esr.
Also, distributing old tor-browser versions to our users is not kind of us to them...
@irl @starbreaker @ajroach42 for 6.5 it wasn't a very good experience but not due to porters. Firefox certificates expired a few days after we released 6.5, then tor-browser did not have any plugin.
This was fixed in august when we started shipping -stable packages but meanwhile, it was a poor experience IMO :(
