 Dear Tor Developers,

 Since the release of the tor-browser bundle 3.6.2 for linux, I see a
 strange error when tying to install the firefox add-on "certificate
 patrol 2.0.14".
 The tor-browser aborts the installation with the message that an error
 appeared during the installation. Moreover it calls the addon name "null".
 The Browser Terminal displays the following error on that issue.
 > [14:24:13.463] WARN addons.xpi: Download failed: TypeError:
 aAddon._repositoryAddon is null @

 This happens not only when trying to install the addon from the
 mozilla server, but also when trying to install it from file.

 Finally, I have testet the addon on other firefox profiles. None of
 them displayed that error and the installation of certificate patrol
 like a charm. So it seems to be that the error comes from the tor-

 The certificate patrol addon may be old, but it is the only firefox
 addon, which can detect if an ssl cert is renewed/switched on an
 website (without sending any data trough the web).
 This can help against an man-in-the-middle attack on ssl
 Therefore, I consider that install error of that addon a problem.

 So please take a look at that issue.....just to see, if its related to
 the tor-browser or to a completely different source.
