Same here..I don't even have another browser installed on my main machine. Never have the need for it, FF works great. I think the OP has too many plugins :)
My addon list isnt that big either... it's just that I disable a lot of things as well, like webGL and other stuff. Suprising number of sites needlessly use these things.
Follow https://github.com/tridactyl/tridactyl/issues/2712 if you want updates when that's added. It would help if you could link to the website that hijacks ctrl-f in that issue :)
