I'll revisit my options when/if Chrome breaks uBlock Origin on stable
That and my having seen repeated assertion by HN user tptacek that Chrome's security team is the second best in the industry (behind only the iOS security team).
Well, that and the lack of any signs that Mozilla management was prioritizing improving Firefox's resistance to malware. (Mozilla's interest in using Rust I saw as a positive sign, but not particularly directly relevant to the question.) At the time, one of Mozilla's priorities was introducing a new mobile OS.
I've swapped to Firefox before, but there's always things that annoy me every time I do.
Having things like the Bookmark Manager and the History panels as separate windows seems to get in the way, particularly when the interface is usually worse. I much prefer Chrome's history tab, often for no other reason than it's sorted by date instead of alphabetical. In Firefox, I seem to have to use the separate history window to sort it that way. Even if it is fixable, you would have to spend a few minutes working it out, which is a problem.
Then there's just small stuff that gets in the way. One thing that happened to me recently was that I wanted to look at a background image for a div. You can't right click and open in a new tab for these, so I inspected it in the dev tools, and in the style panel, there's a link there, but you can't click on it. In Chrome, you can right click on it and go "Open in New Tab", in Firefox, the closest option is just "Copy URL" - which means I have to open a new tab and paste it in.
Chrome just in general seems to have a better UI/UX.
- Better track record of security, better security architecture overall. (Firefox is getting better, but not there yet)
- Very smooth account sync across devices and platforms.
- Credit card payments with Google pay is very convenient.
- Good spell checker
- Good Google integration overall.
- Development tools
- Crashes are very rare.
