It seems to not work well with ABP and NS which are two plugins I refuse to disable. Forcing ads is pretty dirty and should be optional.
The addon itself is actually one of the best screenshot tools that exist. If it were not for the conflicts with ABP and NS I would use it for sure.
For now I'll stick with pix.am which is very small but sadly they do not offer a addon for any browser. Capability wise it does not hold a candle to FS but at least there are no ads lol.
