Including:

* In the "customize" view, drag and drop of icons to and from the toolbar doesn't work.
* Which makes it kind of hard to remove the much-maligned Pocket integration. (But at least means I can't enable the also-much-maligned "Hello" integration.)
* If I try to drag and drop tabs in the new tabs page, they don't move, but it does prevent using the page anymore.
* For some reason tabs in new tabs have not 1, but 2 "pin" icons. But the one at the bottom does nothing when clicked on.
* The "pin" icon at the top does something when clicked on, it turns from light grey to light blue. These colors are nearly indistinguisable in such a small space. Bad UI design.
* The "new tab controls" popup has check boxes that do nothing when you click to uncheck them. Because they should actually be radio buttons. More bad UI design.
* It changed the font used on web pages to something else, despite my having carefully selected some font or other.
* Any font selections I make now seem to be ignored, even though I've told it not to use web fonts and even if I reload pages.
* They broke dragging tabs to reorder/move to another window. Wow.
