I know Firefox extensions that allow protecting (cannot be closed) and locking (cannot change URL) tabs. What I need is an extension that locks a tab to a certain domain or URL pattern.
For example, I want to lock a tab to the domain
example.com. As long as I follow links that are within this domain the tab should show normal (unlocked) behavior, but if I follow a link to another domain the link should be opened in new tab -- leaving the locked tab open with a URL within the locked domain.
Even better would be the functionality to lock a tab to a URL pattern. If a URL matches the pattern it is opened in the current tab, otherwise it is opened in a new tab.
Do you know something (preferably an extension for FF 8.0) that provides this kind of functionality.
