About this extension

What does this add-on?
It tests a current URL in your browser with three performance testing tools with one single mouse click:

Google PageSpeed Insights
GTmetrix (GooglePageSpeed Insights and Yahoo Yslow)
Yellow Lab Tools

Extension works very simple:

Install Add-on
Navigate to the url you want to test
Click on the add-on button in the add-on bar on the to right of your FF
Magic!
Test results from all three test tools are opening in new tabs immediately!

Note! You maybe need to wait until test results of certain tools are ready. Test queues exist mainly at GTmetrix - other both tools deliver test results after just a few seconds of wating.

Have pleasure with performance tests and may the performance force be with you! This time-saving add-on is brought to you by https://mediaworx.com, full circle media agency from Berlin, Germany
