 Replying to [comment:3 cypherpunks]:
 > Just wanted to write from a user's perspective, the only addon I used
 with Tor Browser was DownThemAll as it made downloading multiple files
 much easier. At the moment I'm trying "Simple mass downloader" since
 DownThemAll isn't compatible with the new Firefox.

 > Can Tor try to proactively fix anonymity or security related issues from
 addons that are most likely to be installed on Tor Browser? It may require
 some research to figure that out. My guess is download managers/helpers
 and adblockers would be among the most popular.

 No, that's not feasible. And, frankly, we should not be in the business of
 evaluating all sorts of combinations of installed extensions at all and
 what that means for user anonymity. Oh, and even if we could do that once
 at a specific point in time that would not be enough. We'd need to monitor
 that over time for all (most popular) extensions.
