I recently installed vimium on chrome, and being able to quick navigate to a specific tab via keyboard (by typing the title or selecting it from a list) has completely eradicated my issue with finding tabs on chrome. There's something like vimium on Firefox, but I haven't really looked into it. I mainly use chrome because I use chrome. I just don't feel like putting the energy into setting up Firefox how I like it. currently, my chrome history is synced between a bunch of devices nicely. Between setting up that and having to find alternatives to all the addons I use, making the switch just doesn't sound fun.

Vimperator. It offers more functionality/hackability than Vimium as well (not that vimium is bad - I'm a happy user of both firefox/vimperator and chrome/vimium).
