Could you name another browser with enough backing to be able to keep up?

Besides Google Chrome (controlled and backed by the surveillance overlords) and Safari (Kept alive by Apple cultists) I see very few free alternatives that can stand on their own. The other options are various niche browsers that leech on one of these three that might have a few changes here and there but lacks the real capability to stand on their own legs.

What I mean with capacity to stand on their own legs is that the group behind it should;

  * Be able to be a part in development of web-standards

  * Be able to keep up with ever changing web-standards

  * Be able to suggest and develop new web-standards if needed

  * Be able to maintain a modern web-browser

This needs a relevant user-base, active developers and standard-committee members as well as infrastructure and cash-flow to maintain it for expected stuff like add-ons and various other bits needed (on-line checks, certificate handling, etc) that is expected from a modern browser.

I am worried about Mozilla but I see no reason to declare that the end is nigh just yet.

Firefox is still very much relevant to me, although I use mainly linux-distros and do not normally use webpages as applications (I browse with javascript disabled, unless there are specific needs). I would love to see some more options out there, but alternatives to Firefox are currently not on the horizon for me.
