My Reviews

Clear Cache Button

Programmer didn't respond Not yet rated

I sent two requests at the programmer. He didn't respond. Maybe in 5 years there will come a new update. That's not the way of keeping an addon alive...

This review is for a previous version of the add-on (0.5). 

Headr

This is possible PHISHING software! Not yet rated

This addon needs at least a good Privacy Policy!
Default behaviour could be used for phishing!

I downloaded the addon and changed/blocked xmlhttp-requests to report what is going on to me.

Every 0.5 seconds all browsers locations are scanned. If there is a new location it is pushed onto a queue stack. After 10 seconds a request is made to a server (http://85.17.163.193/Headr/).

The problem is:
EVERY url is reported to that server. There is NO filter to restrict reporting. Searches on google including complete search text are reported as well as visits on HTTPS websites!

You don't have to click on a button of that toolbar. ALL your visits are reported to that server automatically!!!

I could not recommend to let this addon out of the sandbox.

This review is for a previous version of the add-on (0.0.0.15).
