CloseReview for Priority Switcher by Simpleman
Rated 5 out of 5 stars
Tested on Thunderbird 45 with no crashes. Seems to still work fine. Maybe the previous reviewer had another incompatible add-on which caused the crash.
This review is for a previous version of the add-on (0.6.14).To create your own collections, you must have a Mozilla Add-ons account.
