I have been using it intermittently for a year or so. It is OK, and I’d probably like it if it did a few things differently. But I have a particular way that I use the internet, and it just does not work the way I like. If I had started out with it, I probably wouldn’t mind, but a twenty year habit is hard to break.
I’ve been using it on my iPhone as well as desktop since it came out. They must have done an update for the phone app recently because now all the settings options have migrated from the upper left part of the app to the lower right.
