If you can't find the answer on their Support site, send them an email, link on the same page. There may be a patch you have to install to make the app work with Firefox 4.0

S o l u t i o n : Just go to their site qfxsoftware.com (as seen in firefox "Add-ons" "Keyscrambler" "More".

Their at "Download" get the Free Download Version for free, or Download the Pro or Premium Version (not free).

KeyScrambler_Setup.exe has actual 1.164KB

Install and voila, you have Version 2.7.1.0 and it works with Firefox 4.0 !!

AGAIN, this nice Ad-on hasnt updated itself via the Firefox Browser, like it didn't when the last Firefox Version was new!

Why? I think KeyScrambler is one of the most important Add-ons for my Browser, beside the Add-on "NoScript".

Also when you search for "Key-Scrambler" via the Browser-Add-on-Search you cant find this Add-on anymore!!

Maybe our Goverments didnt like it? ;)

Think twice . . .
