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

Avast Free Antivirus / Premium Security
1

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. :frowning:

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. :cry:

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?? :smiley:

Yes, that is what Pavel said.
