Hi, Firefox folks. My text (and edges of tabs) were blurry in Firefox 4.0.1 (32-bit), running on Windows 7 64-bit, with a Radeon HD 6670 with latest drivers: Catalyst 11.5, May 9, 2011. (I have no text problems at all with the latest Chrome or Internet Explorer 9.) The problem immediately disappeared when I went to Firefox's Tools menu --> Options --> Advanced tab --> General subtab, and unchecked "Use hardware acceleration when available." [I've edited out a "tip" of mine that I thought was working, but actually wasn't.] I don't know how this will affect Firefox's speed, but at least I can properly read the text now. I didn't have to disable Firefox 4.0.1 hardware acceleration with my old NVIDIA GeForce 9800 GT (which I was using on the same PC a few days ago), so this might be (at least partly) an AMD/ATI problem; I've notified them about this already. So, either AMD/ATI needs to issue a patch, or Mozilla does, or both. Just thought you should know. Thanks for your time. --Chaz Geary, St. Louis County, MO USA
