Q:

wordpress: add/edit link button doesn't show in visual editor

So the problem is there. Wordpress 4.2.2. Custom self made template(no wp edit, just bootstrap, "lightbox", jssor slider and content parsing php functions for displaying). After adding pictures on pages there should appear add/edit link and remove link in visual editor. See picture I am talking about.

Everything works fine for me and at any browser(including Chrome) and different OS.
However for content maker, who is filling pages with content atm this buttons are not seen. We are using same user. His OS is win8.1, browser Chrome 43.0.2357.134 m. His screenshot is there.

Any ideas how to turn those buttons on? Already tried plugins which modify add/edit, as well turning off and turning on visual editor.

A:

So the problem wasn't solved by any cache or data clearing in browser, incognito mode are reenabling visual editor or TinyMCE fixing. As well no plugins conflicted it.
It was browser's settings problem and was solved by reinstalling Chrome.
