After installing Mozilla Thunderbird 6 I quickly discovered that one of my favorite add-ons was no longer working. Firetray is listed as incompatible with Thunderbird 6 but after searching around I discovered that it worked for some people after they compiled it from source.
Searching around in the build files revealed that the add-on needs a version bump to properly install. Once I changed the max version number and compiled the add-on it worked flawlessly!
You can download my x86_64 build or follow the steps below to compile it on your PC. The patch file (in the steps below) will bump up the version number. Compiling the add-on requires you to have gecko-sdk and scons already installed on your system.
mkdir firetray cd firetray wget "http://firetray.googlecode.com/files/firetray-0.3.1-src.zip" unzip "firetray-0.3.1-src.zip" wget "http://pavelshub.com/files/firetray-thunderbird6.patch" patch generate_install_rdf.sh firetray-thunderbird6.patch ./build.sh
