Welppp, that's a sad chart. Though I really doubt Firefox's drop in market-share is that tied to performance. The story is more likely to be Chrome/Chromium as the default on Android, the release of Chromebooks, etc. Of course, this is just me interpreting facts with my feel good opinion. Back to the main point at hand, though, Firefox is obviously not doing well today either according to that chart. But its performa…
performance, yes, dev tools are lacking all the listed features historically speaking, Chrome got the share it got because Firefox was a memory hog and was running a purely interpreted JavaScript engine on top of a single threaded rendering engine in a time where core numbers and web app were becoming mainstream.
I must admit that I've never used those missing dev tools in Chrome, as those issues are non-existent in a webpack environment (that's essentially what workspace mounting and hot code reloading is mirroring). And the search function works with all files, including inline code, as of Quantum as well.
