I was surprised that I didn't see Unified Search in the list, but when I
checked, I noticed that it now only has 204 average daily users. I imagine
this add-on has been quite popular, but it hasn't been updated for a long
while, so its latest compatibility has been with Thunderbird 52. When you
view the statistics for this add-on, you'll notice a drop from around 1400
ADU to 200 now. I think it has been even more popular before, but those
stats aren't available anymore, at least not on ATN:

I have supplied a patch to the author on github with which for me it mostly
keeps on working in Thunderbird 60, although I haven't checked if
everything works, only the features I use.

It would be nice to see which other add-ons have such a drop in daily
users. It can very well be that people still using those add-ons are still
using old, unsupported version of Thunderbird, so if we find ways to revive
those add-ons, we can maybe get people to upgrade their version of
Thunderbird as well.
