My Safari has become hot garbage. It keeps forgetting what tabs I've had open. Usually it would just forget them once in a while, but now it's every time I hit the red "close" button in the upper left corner. When I open Safari again it starts fresh. This sucks tremendously, so I am hoping a reinstall of Safari would fix it. However, I don't know how to do it properly. Do I just drag it to the trash bin and that's it? Or do I need to clear all kinds of cache and stuff first? Also, where do I re-download it? I can't see a download button on the Safari page of apple.com..? Finally, if I delete Safari, can I be 100% certain that my iCloud bookmarks won't get deleted with it?
