The setting to allow WebGL used to be available under the Security tab of Safari preferences. Now I can't find it anywhere. https://newchat153.weebly.com/download-citrix-for-mac-free.html. Not under that tab, not in 'Settings for This Website' and not under 'Develop' in the menu bar. Does anyone know how I can enable WebGL?
After upgrading your graphics driver. Reboot your computer to use the new graphics driver. I still have problems with my graphics card in Firefox. Unfortunately, due to the wide range of possible driver, video card and operating system combinations, hardware acceleration or 3D web graphics (WebGL) may still not work for you in Firefox. While your browser seems to support WebGL, it is disabled or unavailable. If possible, please ensure that you are running the latest drivers for your video card.
