Thanks for reporting this.
Please provide exact steps to reproduce. "Go to a page" isn't. :)
Also, which exact Java version?

1. Go to page
2. Click on the button "Avvia il test"

I have installed Java 7 update 55
the applet uses about 50 Mb memory RAM

Hi all,
Any news about the problem?

Thank you
Hi Giovanni,

I had to activate a blocked applet on the provided page in order to start the java applet. After an internet speed test was performed with no possibility to scroll the page and no issues observed. 
Can you provide a different test case where the scroll issue is present ? 

Also, please try to reproduce this on the latest release(43.0.4) and/or the latest Nightly ( and provide the results? When doing this, please try to reproduce with a new clean Firefox profile, maybe even in safe mode, as some of this issues may be caused by third party installed add-ons or custom settings(
