I don't really like the new update much, the new tab boxes are much smaller and narrower it gets more jumbled for me (as a person that normally keeps 15 tabs or more) I dislike the new homepage and it just looks gross to me, like it tries too hard to be square and modern. Anyway I'm wondering if I can undo this update in any way?
