Recently, it has stopped closing the pages by double click. According to my observations, it usually does not work along the edges of the page on a homogeneous background, you have to look for a place on which it will work.

It works! The downside is that any double click (enlarging a map or highlighting a link) also closes the tab. If the sensitivity or the timing of the clicks could be adjusted it would be a really helpful extension. Sadly I had to disable it. Way too many tabs disappeared.
