Links not Working in Safari after Yosemite Upgrade

I was facing this issue on both Google search result pages and Facebook on a brand new 13" Retina MacBook (2015) running 10.10.3. At least for me, Safari seems to start returning server connection error messages either once I've had a given webpage active for an extended period of time (>5 minutes), or have performed some activity on the page--such as opening a link in a new tab.

i.e. On Google results pages, after opening a link, the rest of the links become inactive and return an inability to locate the server message. On Facebook, newsfeed images and images sent through the messenger windows fail to load after being on the page for greater than about five minutes. Ultimately, a refresh of the original page allows me to keep browsing (though it gets annoying when Safari presumably tries to reload the cached server response error message page corresponding to the link, rather than the Google page that linked to it).

This probably won't be a fix for everybody, but if you are on a laptop navigate to the "Stop plug-ins to save power" setting in the Advanced pane in Safari preferences (⌘, --> Advanced), and uncheck it if it's checked. It seems that Apple automatically enables this setting, so it's something you have to manually disable after the fact. Unchecking the box appears to have resolved the issue for me, but I've only had it set as such for about an hour. I'll provide an update tomorrow to see if it stays fixed.

Update: Unchecking the "Stop plug-ins to save power" setting has somewhat alleviated issue, but hasn't totally stopped it.

I found that turning off the "dictionary" extension in Safari solved the javascript problem I was having on Apple.com. Try turning off your extensions and see if this helps. You can find the toggle in the preferences menu in Safari.

Thanks Spoondoctor this worked for me. Since I don't use the dictionary plug in that much I just deleted and all seems fixed now

Dear Linc Davis, Thanks for your reply to telletran1. Based on your advise, I've discovered that the problem im experiencing with safari not opening websites is specific to the main admin user.

in the safe mode safari seems to operate perfectly.

I have carried out all instructions/suggestions made on this site and a few others, but the web pages just wont open.

So Far: i have deleted the caches, preferences, and cookies, removed all website data.

And still nothing.

Is there anyone out there that has an idea of how to resolve this problem? Please help.

a Desparate woman in Africa with slow internet! :-(

Wow - what a hassle. I've got the same problem on a Macbook Pro I bought TODAY. And it is happening on the iCloud website! I turned off the "Stop plug ins" and that did nothing. Any suggestions?

I still have the problem using Safari. Can't open anything on MacWorld.com.
