Thunderbird add-on Reply Monitor Update

Hello! I updated the "Reply Monitor" extension. I made necessary changes to make it compatible with new version of Thunderbird. In my testing it is working correctly. I want you to test it. Relevant Skills and Experience I'm a Software Developer. I have experience working with Firefox and Chrome extensions. Thunderbird uses most of the same code base as used by Firefox but it also has functionality of its own. Proposed Milestones $50 USD - Project Completion
