Correct me if I'm wrong but doesn't Firefox have all those features? Why put third party intermediary between you and the source?
Maybe I haven't looked too deep into Firefox multi-profile config, but:
- The distinction between pinned (soft-bookmarked) tabs and other tabs is very useful for me organizing things at work. (I didn't like when Arc added a setting to auto-delete other tabs X days after creating, though)
- Multiple "spaces" on the tab bar combined with global bookmarks at the top mean I can have a space for planning work and one for implementation work, and from both of those I have an easy link to Jira to search up tickets without needing to hop back and forth.
Personally, I just like the design of Zen more. With Firefox I felt like I was stuck with the same old UI forever. I'm not sure what Mozilla was doing with those bags of money from Google. I imagine Arc managed to do a lot more with their browser with way less money than Mozilla.
1) No they don't 2) Zen had them first
Firefox is "copying" from Zen, and I think that's good. I do like Zen, but I wouldn't mind having all the features in Firefox (and imho some of the UI lately in Zen is... weird)
