Safari Lagging on Twitter/Youtube/Outlook on the Web

[MacGekko]

I'm trying to determine if there is a fix, about one or two weeks ago Safari started lagging only on specific sites and trying to do specific things, for example trying to delete a youtube video from my history, 5 or 10 second lag.

Clicking a specific tweet, exiting a tweet. Trying to move between folders in web Outlook. Typing in the Twitter search box. Clicking a link within Twitter.

Using Yosemite, only extension is adblock, tried all of the traditional methods that are recommended and it has not resolved the issue.

Chrome with adblock produces no lag on these sites.

And now suddenly safari is back to normal. I wish I knew why it lagged to begin with in order to avoid future problems, if anyone here knows the reason, please respond.
