I don't think that is the way they work
Since this effects Roboform versions 7.6.1 and lower, and your image shows avast! EasyPass version 7.5.8, I wonder what the policy is that they have with RoboForm about getting the latest updates.
Problem being the RoboForm site shows 7.4 as latest, digging much deeper to find a change log, is their version news page, shows version 7.6.3 is the latest,
http://www.roboform.com/support/news. This and 7.6.2 had a whole slew of firefox fixes.
One specific to firefox crashes:
* Firefox: fixed crashes related to using own build of Gecko SDK - use official build.
Don't know how avast go about updating EasyPass to this version.
