The problem with Firefox is not that it frequently reads and writes to the disk. It almost never does, especially if you disable the cache on the disk.
The problem is it handles a huge amount of memory just to display the pages. The engine is inefficient and it leaks like there's no tomorrow. To be fair, it was even worse.
Anyway, as the working space used by Firefox approaches to 10 figures (in bytes), just occupying that large a space becomes a burden on the CPU. Hence we have the unresponsive Firefox problem.
Moving the application to ramdisk would not reduce its working space, so it would not have any appreciable impact on the responsiveness front.
Chrome is simply more efficient in terms of memory use, so, ramdisk-or-not, it would work faster than a Firefox.
I still use Firefox though, as (i) I'm hooked on the add-ons, and (ii) I'm not inclined to have another piece of software to report everything I do to the US government. I know Chromium is open source, but I don't trust Google period. And yes, I feel hypocritical while typing these on IE. But that's a story for another day.
