Features

• Edit the title of the currently open tab. Done.
• Edit other tabs' titles?
• Add this feature to the tabs' right-click menu, where you currently see things like "Reload tab", "close tab", and so on. I would do this if I could find out how.
• Add this feature to the page right-click menu.
• Add setting to save tab titles between reloads (idea from this review). Disable this feature in private browsing mode. Warn user of privacy implication.
• Mention in AMO description how to use
• Add keyboard shortcut (Ctrl+e?)
• What about possible code injection, is this a security vulnerability?
