Chrome

If you are Linux user, then (according to  http://www.borfast.com/blog/how-enable-webgl-google-chrome-linux-blacklisted-graphics-card) you can try running it from commandline with --enable-webgl and --ignore-gpu-blacklist switches:

$ google-chrome --enable-webgl --ignore-gpu-blacklist

It should be working for other operating systems too. Moreover, you can set appropriate flags with  chrome://flags/ URL in your Chrome browser.
