Anyone else? Running Snow Leopard 10.6.8. I just updated to Safari 5.1, and find it extremely buggy: Back/Forward navigation buttons dont work Toolbar customization doesnt reflect changes when adding/removing buttons - they disappear and needs to relaunch to show changes. Some plugins and extensions (e.g. TastyApps' WebSnapper and/or Videobox buttons, ClickToFlash) no longer work does not allow me to open additional windows does not allow me to empty caches and reset Safari It has crashed for me 4 times in the past hour since I installed it, it becomes unresponsive, and needs to be relaunched every time. So, I'll switch to Firefox/Chrome while they sort it out, or until I feel ok to upgrade to Lion - perhaps then Safari will work as good as usual. I wont upgrade to Lion until I have some time to test all my work apps. Other experiences?
