[7127] Firefox addon extensions do not work

[anykey]

Hello folks, I have been using Seven since 7000. I now have 7127.
My problem is with Firefox xpi extensions.
I have read in the past that this is a known issue with installing xpi, but do you think I can find it now

My Firefox addon extensions do not work, nor do they uninstall/reinstall.
What do I need to tweak, please...

Which add on doesn't work which version is your firefox???
Presently on firefox and all the add ons working which ever I tried to install...

Yeah mine used install nicely, but not now with 7127.
Using latest Firefox - does it make a difference to the problem?
Problem is with installing xpi's in general, not a specific extension.
I know there is a fix, searched but cannot locate it.

Open a New Tab and type about:config Then follow as shown in the picture, please check xpiinstall.enabled is true

Hope it helps

Yes royalhunter, and that don't work either.
I am sure there is a tweak to some settings that needs to be done.
