IE 11 refuses to add some sites to favorites

What's all that extra gibberish even for?

Well, I am going to guess that the "src=google" part would suggest that the OP came to the site from a google search either directly or somewhere back down the line.

This is irrelevant to the discussion, but , Sevenforums added those two smilies to my previous post.
Seemingly, -the colon symbol followed by p- can represent the "Stick Out Tongue" ,and, -the colon symbol followed by D- can represent the "Big Grin", so those two smilies were inserted in their place.

Stopped using IE a while back due to this issue, maybe some sites are blacklisted .
