>>dochtm+(OP)
I'm not a webdev so I mostly don't care as long as it's FOSS, but I will say that firefox loads a lot faster than chromium on my machine. Looking at top it appears that somehow firefox is actually using more memory than chromium is (i only tested a three tabs open in each browser so maybe they don't scale the same under heavier load) but at the same time I can report anecdotally that in addition to being slower, chromium also causes my HDD to make way more noise than firefox ever does.
