The Firefox Add-ons website usually has the most up to date version of each add-on.

Clicking the tab indicates you've seen it, and the icon changes back to the original. Find a version of the add-on that is compatible with your version of Firefox. * Little dancing C4C letters in the tab icon. That's it! Leave the tab open and when a change occurs, you'll be notified. The tab icon will indicate this page is being monitored by changing to C4C. In the Check4Change context menu, select how often to check.

The paint/navigation mode can be toggled on/off, which let you access elements of the content for following links, or interacting with the web site. This implies that any drawing will scroll with the page that it overlays. The paintable surface is anchored on the content that it overlays. This surface area can then be painted with variable width stroke using a stylus pressure. This addon, when enabled, overlays the largest scrollable area with a transparent drawable surface.
