Firefox diabled my Avast?

[highup]

I updated Firefox to 43.0.1 last night. Now if I click open my Tools tab then click add-ons, it shows this.
The second image is a printscreen with the Avast user interface layed onto the Firefox add-ons screen. Avast is working, yet Firefox says it's disabled?????
I don't get it.

I think I got it fingered out......... That's not the Avast antivirus that was disabled, so everything is OK. I forgot Avast had that other program.
