Avast Online Security not compatible with Mozilla 43 64-bit version?

[REDACTED]

Oh noes...

I just installed the latest version of Firefox. Since I am running a 64-bit Windows 7 OS, I decided to try out the new Firefox 43.0.1 64-bit version.

Every addon/plugin works just fine, but for some reason the Avast Web Protection addon does not load into Firefox 64-bit. 

I tried everything, doing a fresh install of both Firefox AND Avast, but I still don't get the Avast Security addon loaded into Firefox.

This was never an issue before, so I wonder if it has to do with the fact that it's now a 64-bit program. Is there a fix for this?

Please help, I don't want to browse the web unprotected!

Thanks in advance for any help.

That didn't help. I switched the parameter to "false", but the Avast Online Security addon still isn't showing up in my addons list. Do I have to reinstall Avast again for it to work?

control panel > software > avast > change > disable the AOS
Reboot and enable it again.
See if that solves it.

I don't have a checkbox for "Avast Online Securtiy", only for "Browser Protection". I did as you suggested with that one, but nothing has changed. The AOS is still not showing up in Firefox's addon list.

Okay, so my guess was correct then.  This is really disappointing as I was so happy that Mozilla finally released a 64-bit version of Firefox! 

P.S. All my other add-ons work perfectly fine... bummer AOS doesn't.

So, I completely removed the 64-bit version of Firefox, did a clean uninstall of Avast (using avastclear.exe), reinstalled Avast as well as the 32-bit (!) version of Firefox...

...and guess what? It is still not working!

There seems to be a compatibility issue between Avast 2016 and Firefox 43.

Help?

As workaround you can use Firefox ESR.

I went back from Firefox 43.0.2 to Firefox 42.0 (the 32-bit version, too, since many plugins don't work with 64-bit) and everything is in order now.

I hope that both Mozilla and Avast will come up with a working solution for this problem in the near future.

Cheers!

Avast browser extensions prior Avast 2016 SP2 couldn't be installed into a 64-bit Firefox. 64-bit Firefox support was added with SP2, released the previous week.

Wait. You mean I could install the latest 64-bit version of Firefox and my Avast Online Security add-on will work??

Yes, that is what Pavel said.
