No need to be revisionist. Chrome brought amazing work to the table. The multiprocess, sandboxed system was incredible - it's not to say that Chrome was the first (IE did it earlier) but it was certainly way ahead of Firefox for a long time. Chrome is the reason we have Seccomp V2 on Linux. Chrome made "software is always up to date" the standard. Before Chrome, Blackhole and PoisonIvy absolutely ruined people's comp…
I remember for a while that Firefox had a single process architecture for all tabs. This often frustrated me as one bad tab could just crash the whole browser while Chrome used separate processes for each tab, prompting me to switch to Chrome for a bit. Firefox caught up ages after chrome, and now I went back to them over the manifest v2 stuff.
Chrome was the first browser to be immune to all of those functions.
Mozilla really screwed the pooch not long after. Their biggest single misstep was forcing automatic updates in corporate networks. At the time, they still had pretty good adoption in the kinds of environments that had a couple of people somewhere deciding what everyone was allowed to run on the company computers. Chrome had already moved to forced updates, so these environments went to Firefox. When Firefox decided to follow Chrome, they no longer had that differentiation, and corporate IT had to choose between two browsers that both had automatic updates, but one of them had frequent memory and performance problems.
I've happily returned to Firefox a few years ago and don't have Chrome installed on any device I control.
