64bit Linux Rated 5 out of 5 stars
A shame that 64bit Linux is not officially supported, since that's what everyone I know uses. AFAIK lightning should be platform-independent, since it's written in a scripting language (no binaries as far as i can see).
To prove my point I tried editing "install.rdf" inside the xpi:
-> Added the x86_64 line below the _x86 line.
Seems to work like a charm.
Only drawback as far as i can see: Updates are (obviously) broken with this.
