Recently I setup my pc with windows 10 and installed firefox ESR 52.3 But I'm unable to install most of the pentesting addon. Like: Tamper Data, Live HTTP Header, No redirect and many more... Everytime it shows me "This add-on is not compatible with your version of Firefox. "

I have tried this on this versions of Firefox ESR 45.7 46.0 & 52.3 also tried on under 40.0 version... but no result :(

Not only me most of the user have same problem.. Please fix this problem as soon as possible..

Note: I was able to install those addon on my Firefox ESR 45.7 before setup my laptop

Some add-ons may not be available for the version of Firefox you are using. Check the add-on's description.

Then which version of firefox can solve this problem? My friends are also using the same addons but they don't have any problem with this... And I also used those addons on my firefox 45.7 before setup my laptop...

I have a 'Download Anyway' link with those extensions. This add-on is not compatible with your version of Firefox. View other versions | Download Anyway

Try these links and install the extension locally via the cogwheel menu on the about:addons page
