"Checking Compatability of Add-ons" Update window at each startup & redirects to a welcome page. Tried disabling all add-ons & updates / force compatability checker. Thoughts?
Each time I start Firefox a "Checking Compatibility of Add-ons" update window appears, which redirects me to a welcome to Firefox 5.0 page with my normal home page in another tab. I tried disabling all add-ons and updates as well as the force compatibility checker. I think my AVG safe-search bar might be causing the problem, but I have it disabled and never use it. Please help me get rid of this.
