Exercisereports.com uses Snap.com javascripts which causes pop-up mini web pages to appear that correspond to the outside link that is rolled over by the mouse, trackball or trackpad.
Using Firefox 2.0.0.11 or greater, the user has the ability to disable or enable the context popups. The default setting is to disable the popup miniweb pages or context menus. Some people find the popup mini-webpages very useful because they can see the page without actually committing to going to the outside website, and then decide if they want to move on to the other website. Others find the unexpected pop-ups annoying and distracting.
Here are the instructions for changing the settings.
Go to Firefox Preferences Menu
Click on the Content Tab
If you want to allow the popups …
Click on the “Advanced …” button and “Disable or replace context menus” should be unchecked.
If you want to prevent the Snap.com pop-ups, but you still want JavaScript enabled …
Click on the “Advanced …” button and “Disable or replace context menus” should be checked.
Disabling JavaScript also stops the context menu or mini-Web Pages from appearing
