Lovely extension, some discussions about its functionality can be found in this thread [0] after the removal of the extension from Chrome's Web Store.
One things I noticed is that it can be too aggressive from time to time. I encountered this "issue" when creating a Bitwarden account, I was unable to verify my e-mail address because ClearURLs was (unbeknownst to me) removing some of the parameters from the activation URL. While similar cases will most likely not be frequent, it can be really frustrating to determine why something does not work (also applies to ad blockers).
