Working fine Beta 21! Rated 5 out of 5 stars

Not sure what some of the comments are about but
Windows 7 64 bit Running Firefox beta 21 and all functions (including save image) works fine.

Also had no problems with previous betas. Hope those users get a fix for whatever is causing problems for them.
