I tried to look at UK Covid map (https://coronavirus.data.gov.uk) on my Zorin rig yesterday, using (latest) Firefox 64bit browser. After a bit, received message stating WebGL is needed.
From reading a number of posts on different websites, I am still unclear whether my graphics hardware is capable of WebGL, or if it is a graphics driver issue. Software updater shows no additional drivers are available for my machine.
Graphics: Mobile Intel 945GM Express Chipset Family
NB: I booted same machine into Windows and got same result from browser.
Any ideas anyone?
