Thank you! I will look into all of your suggestions, some great info!
For a page you frequently visit, if there is an embedded ad such as "Joe's Heating -best prices" for example, one of the addons allows you to right click on it and select: Block An Ad On This Page.
Just be careful not to allow a too aggressive setting, as this can block some webpages entirely that require an ad be displayed before the rest of that page will fully load.
