Unfortunately, even after any graphics (WebGL) related improvements, on my Windows machine Firefox still lacks in graphics performance when compared to Chrome. If I open the new Google maps, it is very slow when compared to Google Chrome. Wonder what is the reason for such huge difference in panning/zooming performance. What is Firefox lacking here? Anyone knows more about it?
The other day I noticed that Google Hangouts just doesn't work in my Firefox anymore, helpfully suggesting I switch to Chrome. The cynical person would suspect that Google's dedication to a level playing field is starting to weaken, and that they're just not going to worry about making popular Google tools work well except for Chrome.
Using Firefox 24, I just went to hangouts.google.com and clicked the "Available for your computer" button. "Hangouts won't work in your current browser. You'll need to download Chrome before installing Hangouts."
And a week or so ago somebody invited to a call was told he couldn't join in the version of Firefox he was using, which I'm pretty sure was up to date.
I avoid using it in Firefox; on Linux, it was performing terribly in FF but fine in Chrome.
