To make this addon work with thunderbird 60:
1) quit thunderbird
2) go to your profile folder, go to extensions, find [email protected], unzip it
3) open "content/filtaquilla.js" and replace (a) in line 1180 "for each (var tagInfo in tagArray)" into "for (var tagInfo of tagArray)" (b) in line 1542 "for each (let tagInfo in tagArray)" into "for (let tagInfo of tagArray)"
4) zip it again, rename into [email protected] and replace the old [email protected]

This review is for a previous version of the add-on (1.3.2).
