Q: Safari does not open links from twitter

I filed the bug using this link. http://www.apple.com/feedback/safari.html

I use Twitter less then 30 min I try to delete (rename) file ~\Library\Preferences\com.apple.security.plist and the problem's gone using Twitter over 2 days. It looks like common Safari HTTPS problem (or security feature). Hope it helps.

I don't have that plist.

I have com.apple.security.othernames.plist but not the one you mention.

I still have the same problem after removing the plist and installing the Safari extension. It is mainly t.co links but also sometimes https://twitter.com/ that won't open. I don't have this issue on any other sites that I'm aware of other than Twitter. It's bizarre.

Have the same issue, macbook pro 13 (2015), os x el capitan 10.11.3 safari 9.0.3

Hi again. To me it seems solved since yesterdays release of OS 10.11.3.

Lucky one Nothing changed for me. Safari is a joke.

Ok, no-tco safari extension seems to help for now

That is the link with some workaround that can be a temporary solution to avoid the problem described here.

In quick, there is the boolean key for Tweetbot that lets open URLs as not-shortened:

defaults write com.tapbots.TweetbotMac OpenURLsDirectly YES

Then, there is the Safari add-on that replaces all t.co links with their originals:

Apple so Apple.

Oh, problem still occurs

I did the same.   Everyone here should simply post a bug report.  This is a pervasive problem for Safari and it has trouble with t.co and also some other sites which tend to constantly change their DNS results.

BTW:  the no t.co extension does appear to work for me .... will give it some time. 

This is probably the first "solution" that's really making a difference for me... 99% of my t.co problem comes from Tweetdeck. Thanks!
