In a little more detail...

My name is Juraj Mäsiar and I'm a software developer - programmer.

Last year (2016) I quit my job so that I can fully focus on the things I enjoy the most - programming small 'projects' that makes life easier.
The years of work as a front-end/back-end and database developer payed of and allowed me to implement secure, powerful, lightweight and super fast add-ons that leverages it all.

My add-ons are build using pure JavaScript ES6 without any external libraries (not even jQuery!).

Extremely useful for people with multiple accounts or if you want to keep your "Facebook cookies" in the separate container :)


Must have! Rated 5 out of 5 stars

I've been using this add-on for years and sometimes I forget that Google doesn't provide previews on its search result page :)
Great work! Thank you :)

StrokeIt Rated 5 out of 5 stars


I remember using this addon for a long time and then one friend told me, there is Windows application called "StrokeIt" that does the same thing but in every program!

He changed my life!
