Official Linux support? Rated 3 out of 5 stars
I find this addon very useful. However, it looks like developer has dropped support for Linux versions. It would be nicer if it was metioned in the description.
I have been using version 2.6.0 in Linux environment. Older versions can be found here: https://addons.mozilla.org/en-US/firefox/addon/hide-caption-titlebar-plus-sma/versions/
