I'm sure they want to replace Gecko with Servo but they can't because it doesn't have xul/xpcom and it never will. There was a post a while back about a side project called Firefox.html which is to rewrite the interface in html5 instead of xul.
Anyways they shouldn't replace gecko but instead make a new browser with it's own branding like the Internet Explorer team is doing with Spartan. Because no matter what Mozilla does with Firefox it will never gain market share because they've lost momentum and don't have resources it takes to brute force users to their product like the big guys have.
"never" and "lost" aren't words I would use with Mozilla. Their vision is solid with lots of innovation going on. They have major market share. They are light years ahead in terms of privacy and repeatedly beat all the other browsers in performance benchmarks.
Afaik, XUL is already replaced on the mobile Firefox version. Would not expect it in Rust at all.
Why, because of all of those buzz words? Name any company that doesn't have vision and innovation going on. Also, name any browser that doesn't repeatedly beat the others in benchmarks.
The facts are Firefox has not only lost momentum (as in stopped gaining market share) it's been losing market share.
