First of all, please go to the extensions/Add-Ons section in your browser settings and look for ZenMate (see pictures *1 and *2 below).
If you find the extension it is already installed on your browser.
For Chrome users:
In your browser’s extension settings you should be able to click on “Show icon” next to ZenMate, which will make the icon reappear in the tool bar.
For Firefox users:
Please click on the 3 stripes on the right-hand of your browser. There you will find the “+ Customize” Firefox option. When clicking on it, you should be able to see the ZenMate icon displayed on the left side. Now you can use your courser to pull the ZenMate icon to your browser tool bar, drag and drop it (see picture *3 below).
If you cannot find ZenMate in the list, please install it again directly from our homepage.
