but it DOES work with Pale Moon. if i spoof my user, agent sharecg works just fine with Pale Moon. please add Pale Moon to your list of supported browsers.

AlleyMouse, a workaround is to open a tab to about:config

click "i promose to be careful"

Right Click -> New -> String
Enter "general.useragent.override.sharecg.com" as the preference name
Enter "Mozilla/5.0 (Windows NT 8.0; WOW64; rv:55.0) Gecko/20100101 Firefox/55.0" as the value (don't type the ")

this will now let you surf sharecg.com with Pale Moon.

hope this helps.
