I was having a crashing problem with the newest safari v85. If I had the third box checked in the preference tab for auto fill, the one for "other forms" Safari would crash whenever I searched a website for anything, like google or dealmac for instance. Unchecking the box fixes it all up nice and fine. Just an FYI in case other people were having the same problem. I sent a bug report to apple, hopefully it will get fixed.
