Apple has released Safari 5.1.2 for Mac OS X 10.7 Lion and 10.6 Snow Leopard. The minor version bump reflects the fact that the updated Web browser introduces no major functionality, but rather addresses a number of issues related to memory usage, where it should now be more conservative, and application stability, along with a fix for a bug that could cause Web pages to flash white. Safari also now supports display of PDF files embedded directly inside a Web page. (Free update via Software Update, 38.7 MB Lion/47.1 MB Snow Leopard)
It's still reloads pages when you hit "back". Terrible. Had to switch to FF.
Yea But the USPS Click and Ship won't support it. Talk to their chat and you'll be directed to Google Chrome.
