I have the very same problem with twitter and Google (maybe with some other sites that use https) when I make query from the address bar or sometime when I enter a url. It started right after update to Safari 9.0.1 and El Capitan.
I have tried:
- empty cache
- disable extensions
- clear history
- some manipulations with keychain and certificates (Safari 9 doesn't open some even major sites. Chrome, FF -- ok.) which helped with one site that didn't open at all.
I don't have any firewall or antivirus or any stupid things like that installed on my laptop that could possibly affect the work of Safari. There are only 2 extensions for Safari -- Evernote and AdBlock and with or without them the problem persists.
FF and Chrome are ok.
The problem is with Safari only.
- What has Apple done with the latest update to Safari that made it nearly impossible to work with this earlier almost perfect browser?
- Is there a clear and working solution to this problem?
