Edge 2.09%Unfortunately, they'll be removing the webRequest API [1] which was the only reason I would have wanted to use it. This will happen probably whenever Google deprecates Manifest v2 and Manifest v3 becomes the only interface for extensions, which will stop uBlock Origin from working.
Other than that, when I tried Edge it didn't work perfectly on every site. But, it will be nice to have another non-Google browser to choose from.
