It took me a while to find this add-on and I'm so glad I did. Seems to work well in my short 5 minute testing, i.e. I can search for regular expressions and jump through them using the up/down arrow keys. BTW, I'm not sure what Ckln was saying when he only gave this 2 stars because "On Firefox you can't have a shortcut to make the search pop up that's a shame." I use the default ctrl-shift-f and the search box pops up just fine in my Firefox.
