Are you still wondering which version you're on? (It is all covered in this article).

Step 1. - Go to extensions in your chrome bar from this link.

Alternatively, you can go to extensions by clicking the three dots in top right corner of your browser, then selecting More Tools > Extensions.

Once you are on the page, locate the Mr. E extension from the installed extensions you have.

So your version is 1.9.5

Hope this helps.
