While this add-on does what it should, it also causes breakage that is not just cosmetic. When typing in the search field, the screen is scrollable, which does not happen in Chrome. This can cause the top of the screen--where most webpages have their menu--to be off screen even when scrolled all the way up.

I've seen such breakage on many other pages; unknown if this causes them outside Google's platforms. Currently testing with a clean install of Firefox and only this add-on.

Too bad it hasn't been updated for nearly 2.5 years...
