Rated 4 out of 5 stars

The extension does a good job of finding duplicate emails. There are many comparison criteria. The main drawback for me is the search results field is too narrow (680 pixels). I have 3440 pixels wide, and I can afford to examine the search results table in detail without having to guess the values ​​of cropped cells or using horizontal scrolling. Especially when the number of found groups is several thousand.
