Or IceDragon, its a browser very similar to Firefox and it is meant to be for users that prefer firefox but fixes a lot of the issues FF has. I am not sure if ID would fix your current issue, but may be worth a try. Or there is Vivaldi which has a lot of interesting settings and customizations. Something to possibly look into. Same as with ID, I am not sure if it will fix your problems, but I am trying to give options for those that don't like the idea of Chrome. I know if you're a coder or even a graphics person, why you probably prefer FF, so just trying to offer options that may be within your wheelhouse, if that is the case.
