Have avast 2014.9.0.2008 but...

Updated tp 2014.9.0.2008 but my firefox extension says version 9.0.2006.53. I am having trouble with facebook apps since updating. Are these 2 versions in conflict. Shouldn’t the firefox extension say 2014.9.0.2008?

One thread is enough

Your version numbers are correct, the Antivirus program is 2014.9.0 2008, the extension for FF is 9.0.2006.58

What do you mean, one thread is enough. I never had problems before updating to 2014. Why does my fireShevill vaiknofox extension say a different version

Because you already have another topic, I answered in that one. The AV program number is different to the FF extension number.
