Rated 3 out of 5 stars
I would have preferred contact support before writing a review but I do not know how. Unfortunately, this extension does not work in my case (TB 24, windows). I could set a breakpoint but nothing happens when the execution should stop. Yet there seems to be potential.This review is for a previous version of the add-on (0.9.3.1-signed).
How about using the one of the linkts to the "Addon Homepage" or the "Support Site"? Both would have lead you to a web page where you could have filed a bug report.
I do have a newer version available that works on Thunderbird 24, but it's not yet ready for uploading here. The new version is available from https://sourceforge.net/u/pbrunschwig/tinyjsd/.
