Only Safari? Not Chrome?

For some PCs, it was in Firefox. Others in Chrome. And in some, in both. Also in Safari. But not in IE; never saw the problem in IE

In different browsers, the new addition #.TtRB_LJ2GCo varies. For the same page in different browsers, the URL effectively becomes different

What's the actual problem with that?

True, it does NOT break anything.

But I am very uneasy when you never set your site to have that #.TtRB_LJ2GCo URL extension, and you just wake up one day to find that it suddenly started showing new characters in the URL

It becomes a problem when another site links to my content, and their link uses the new extensions -- and clicking on the link from the other site leads to 404 Not Found error on my site.
