This is an interesting development, I noticed the pop-up on my Firefox yesterday. The reason however wasn’t security it was ‘instability’.
It’s a fair move by Mozilla though as the add-on can cause security vulnerabilities in Firefox outside of their control. They can’t fix the software, so the best thing they can do to ensure user [...]

The latest one that’s cropped up in both Firefox and Chrome is a clickjacking vulnerability. This is basically where a link is replaced by an attacker [...]

It seems a data leakage bug has struck Firefox recently and has been confirmed by Window Snyder the security bod at Mozilla.
It’s basically a Chrome directory traversal bug (It seems a lot of the Firefox issues have had to do with chrome?).

The first which effects fully patched IE6 [...]
