If any Trisquel user facing a malfunction she cannot explain would write in
capital letters that "Trisquel might have been compromised", then the forum
would be full of such messages. If, every other user could simply state,
without any justification, that this is due to a vulnerability in the
application, then that would be the (almost always wrong) answer to every
request for help.
The "reference" you gave does not even relate to Trisquel's browser, which is
based on Firefox 22 and not on the ESR branch. On the correct page, none of
the vulnerabilities of Firefox 22 that were fixed in Firefox 23 (t3g wrote it
was such a vulnerability to have the pleasure to criticize, one more time,
Trisquel's lead developer) has a direct relation with SSL/TLS.
Sure, there exist vulnerabilities, such as this one that "could be exploited
to run arbitrary code". But, now listen carefully: if your system was
compromised, it would not behave in a weird way. When bad guys gain control
over a system, one of their main goal is to not be detected so that the
system stays in their botnet. You can therefore be sure that your your HTTP
connections were not systematically ceasing to be secure because your system
was compromised.
Now please stop bragging about how you are worrying about security. Security
is not a matter of "opinion" (as you write) and you obviously do not know
much about it. And, please stop attacking every user of this forum who
disagrees with you.
