Errors on pages after installing the share plugin

Ok, I confirm that when disabled you still have those javascript issues I mentioned before showing in th ebrowser console:
Uncaught ReferenceError: Browser is not defined(anonymous function) @ validate.js:4
шампоан-против-пърхот-и-себорея-лечение-на-себореен-дерматит-и-псориазис-psoriazis-описание.html:607 Uncaught ReferenceError: decorateList is not defined

These are breaking some javascript features on your page and could be responsible for our plugin malfunction.

Try to disable their relative extensions. to test.
