I hope they fixed the bug where safari would freeze every once in a while when simply typing a few letters in the search bar on 10.11.1.
I've noticed this and I hate it! using chrome for the time being, that issue has been around since the 10.11.0 release
Glad to see that I'm not alone with that problem. What Mac do you have?
I'm not sure if this is the same bug but try disabling Top Sites completely in Safari and see if that improves it. If yes, I'd suggest filing a radar or feedback explaining this workaround to them.
I had that issue after first installing El capitan.
I fixed it by resetting sarafi settings using this terminal command:
mv ~/Library/Safari ~/Library/Safari.old
If it doesn't work, just rename it back and you wont lose your preferences.
