Rated 5 out of 5 stars
Really great one! Hope it'll be updated to work with firefox 57+
Will FS be updated for FF57? Likely, but I'm seriously weighing the option to switch to support Chrome instead. Before I finally update FS for FF57+, I personally just switched FF update option in General to "check for updates but let you choose to install". I will post updates on the status here or on my website.
