Running Win 8.1 on a new Dell. McAfee Site advisor is enabled and causes Firefox to run slowly and in fits and starts. When I disable Mcafee site advisor Firefox runs fine.

Disable Sitadvisor, it's useless anyway.

Hi Richard,

Unfortunately, extensions such as Site Advisor are known to slow-down Firefox. Often, poor memory utilization is the cause; this can lead to slow start-up, crashing, and general slowness loading webpages.

In my opinion, Site Advisor is completely unnecessary, as Firefox includes built-in phishing and malware protection already (see How does built-in Phishing and Malware Protection work?)

In addition, some search engines such as duckduckgo.com have an option to enable Web of Trust (mywot.com) ratings alongside search results without the need for additional add-ons. In your case, I think this would be the best option for you.
