I love it for 1 simple reason, - I trust it, I use firefox as well and I believe they won't use my personal information anyhow in Thunderbird (I wont get any unwanted spam adverts and they wont steal my logins etc.. it's free and it's reliable and trustful).
I hate to give it rating of 5 (It's 10 really), but otherwise nobody will ever read the negative review below. I have no chance to leave feedback in any other way so I found this site.
It's 2018 now, right? Why I need to download things like "Keep in taskbar" (from year 2011) or "Minimize to tray" or "Unread Badge"? IT IS BASIC FUNCTIONALITY, why the hell anyone in the world would want to have thunderbird in active tasks of taskbar when you close it??? When you close it it should just minimize to tray, or I'm too stupid? Why not just make life of 100000000000000 people simple and make it available in settings, or is it THAT HARD? Why need addon for things like this?
Ok, there are add-ons, but today I updated thunderbird to new 60.3.3 version! YAY.. fantastic right? Add-ons now incompatible, I expect a person from 2011 should come now and update it!? I already installed the add-on from GOD knows LOST and insecure place on web to make a BASIC feature like MINIMIZE TO TRAY to work.. now I downgraded to 58.0.2, my addons work, I disabled new updates. Bye bye. More
