Mozilla extension: Minimize windows into the system tray (Firefox, Thunderbird, Seamonkey, Instantbird)
Developing the extension
Once you jumped through the hoops of getting a Firefox or Thunderbird set up for development, you can use a proxy file pointing to your cloned repository.
Please note that while the the Windows implementation uses C++, it does in fact not link the MS C/C++ runtime, so stuff like exceptions won't probably really work, and
delete are implemented with calls to
LocalAlloc. This is to avoid statically linking the massive runtime, and in fact, to avoid having two runtimes executing within the Firefox processs at the same time.
Building an XPI
You need to have python-2 installed and then execute
python build.py in the root directory of your clone. This will automatically generate an unsigned package.
Regarding the now-mandatory-in-Firefox add-on signing: You're on your own and have to figure that out yourself.
