Open Wiki Edit Page par Brett Zamir

Context menu item to translate Mediawiki-style links (as used at Wikipedia) into corresponding edit links (i.e., from /wiki/title or title=(title) links into ?action = edit&title=(title) links. Only shows the context menu if those type URLs are found

You can set your own wildcards, and find-replace patterns if different wikis follow different URL patterns.

Also provides two "Open ISBN at Amazon" options (leading
to the same window or current tab) when right-clicking on a link containing
`Special:BookSources` (the format for links leading to ISBN numbers
at Mediawiki sites).

The context menu options only appear when right-clicking qualifying links, so it otherwise will not clutter the context menu, even for (non-wiki) links.
