No. They're working on a firefox port, but it will take some time (you can checkout the github issue). It's the only extension I really envy.

Firefox does have Adblock Edge (open source adblock without the silliness).

I this point, I am pretty much the only developer (there are contributors for translations, issues), and working on this more as a hobby (I do not want this project to be more than this). As much as I would like to, I just don't have the time to work on a Firefox port for the time being.
