Really fantastic addon with a lot of quality of life fixes on top of restoring the layout to a more old-school appearance. Unfortunately, the addon seems to be breaking down over the last couple months. I can no longer see my own user profile while in "Old Twitter" mode, as the page never loads, and now the Old Twitter mode doesn't load my own user icon/profile links, profile statistics, or the switch user account area. No updates have been getting pushed lately either, and I worry it's only a matter of time before the entire addon eventually stops working.
