Wikimedia+ is a Firefox extenstion that adds history (links to recently viewed pages) to Wikimedia/Wikipedia pages
When you browse through Wikiepedia/Wikimedia pages you often wish to go to a page which you had visited just a few clicks ago. Wikimedia+ lets you do that. It adds a list of recently viewed pages on the left-most column of Wikimedia pages. This gives you easy, one-click, access to any of your last ten pages.
Wikimedia+ is more convenient than using the browser's history list. It is also Wikiemdia sensitive: Even if you edited a page, or visited several subsections of a page, Wikimedia+ will display only one entry for this page.
