Just tried nightly and haven't updated my main version yet. The lack of addons is sad and I'm not confident they'll be adding them back with any haste. However the biggest issue I see is that the default page is empty, theres no one-tap button to add a bookmark in the url bar, and getting to my bookmarks now requires using a small context menu. They really need home page customization, because the whole flow of open tab > click bookmark is just completely gone

Why make using bookmarks, a core piece of any browsing experience, so much harder?

What's the functional difference for a typical user between a 'collection' and a folder of bookmarks? Collections aren't on desktop, so now I need to bookmark and add to a collection.

The menu containing 'open all links' in a collection is hidden until you expand said collection, then click on the newly revealed menu button. This whole update reeks of "UX" department needing to justify their jobs by making unnecessary changes.
