Michael, I'm
glad you responded as you did. I have other Macs that are older than my Mac-Mini, and I prefer to have a "similar view" on each. Google has turned into "Big Brother", in my opinion. I can't get s.p.a.m filters to work properly, nor can I view anything about how the filtering process works. I can't "Post" on most of the new Google Forums, even though I'm a member. Even the search box acts strange...I can't copy/paste within the box. And the list goes on-and-on. But, back to this issue... there is an ENV variable called "HTTP_USER_AGENT" that contains sufficient information for Google to determine what I have for both hardware and software. For me, it looks like this: "Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.4; en-US; rv:1.9.2.28) Gecko/20120306 Firefox/3.6.28". That should be enough for Google to know there's no sense in telling me to get the "latest Firefox browser, which is 12.0, and DOES NOT WORK on any Mac OSX below 10.5.x.
My only alternative has been to switch to the "basic HTML version" of Gmail. Then, when I need something not covered by that version, I switch back to the Standard version. Not pretty.
