Green_Hilltop: That doesn't matter. How many websites do you see that are broken for FF? Basically none. My even older Chrome shows GOG normally, and I don't like the new FF or its switching to multiple tab processes instead of having one.
Also, it works on Chrome (also an older version), so that's solved for me, however if a mod sees this and would like to take a look at what broke it for FF/relay it to the devs, that would be great, since I prefer browsing in one browser.
They did take a look at it. It was outlined
here, where the reply (as expected) is "upgrade your browser."
I've got to ask, why do you prefer the single process system when that can take out the entire browser due to one runaway tab? Are you trying to cram an OS into 2GB or less?
