False positives Rated 3 out of 5 stars
Every time Firefox is started up, it says there are updates but then when you open the websites it says "No changes found".
If you are having the same problem, there is a suggested fix posted below in the comments. I did try that but no luck for me.You can try to set manual watch and ignore regions, see if that helps. If it doesn't, disable other extensions to find any conflicts. The dev does reply to support emails but I found another extension which worked for me before the support process was worked out.
The manual regions is a great feature, give it a try, it may work for you.
