the latest editions of firefox 5 and 6 do not properly install.
I've used Firefox 5 on two machines since it's release w/o as problem.
FF 6 is still only a Beta version.

I finally took a chance with FF5.

FF has had a back and forth history. Some updates created massive havoc; others were great.

With FF5 I lost a couple of add-ons that weren’t that important. They seemed to have cured the severe memory hogging problem. I do like the SYNC feature — as now, I can sync passwords and bookmarks with my desktop and two laptops.

Also, Firefox 5 does load faster than previous versions.
