> Search marks matches in the scroll bar.

That's an interesting feature, I'd like it if that was implemented. I see some add-ons do something to simulate this.

> Opening a recently closed tab opens a new tab in Chrome instead of replacing the existing one.

This opens a new tab for me, no settings I've changed that I could find.

> There were probably 5-10 more annoyances in Firefox for me that I don't recall right now. Maybe it was my familiarity with Chrome but overall I still think Chrome has better UX defaults.

There will probably always be differences, that's why different browsers exist after all, and it'll be different annoyances for different people. Personally I think generally the UX of Chrome (that Firefox has tried to copy) is the worst thing about all current browsers. The new add-on API made me start using custom UX CSS to make it tolerable instead of a "fix add-on", but the only serious alternative (Chrome) always felt worse to me. Has many nifty features though.
