Very useful Rated 5 out of 5 stars

Excellent, this is very useful. Typical use: on an IRC channel, someone writes a bug number, you double-click on it, then switch to your browser, and with one click on the BTS button, your are directed to the corresponding bug page.

Didn't work Rated 1 out of 5 stars

I couldn't get this to work (Debian stable Iceweasel 7). No buttons. Pity. :-(

Try toolbar customization

The buttons aren't shown by default, because there is no single "right" place to add them. The user is expected to add the needed buttons by right-clicking on any toolbar and selecting 'Customize...'

Excellent Rated 5 out of 5 stars

Nice to see an extension build for a max version of Firefox 5 still works well in Iceweasel/Firefox 7.0.1.
Thank you Damyan Ivanov.
