FireFox plugins I can’t live without

I’ve been meaning to write down some of the FireFox plugins I can’t live without. Please add any you think I should check out!

• Not really a plugin, but the JavaScript shell boomarklet rules.
• The Web Developer Extension is a must-have. The two best shortcut keys are Ctrl-Shift-Y (don’t actually click, just float over objects and see their DOM tree in the status bar — easier than the DOM Inspector) and Ctrl-Shift-E (edit CSS, you can tweak CSS styles on the fly, trying out things in real-time).
• Venkman is an awesome JavaScript debugger.
• JustBlogIt is a nice way to quickly blog about webpages you are browinsg.
• Bloglines Toolkit is a great way to keep track of all those blogs. If you aren’t using Bloglines, I suggest you try it out. And check out my blogs too!.
• SpellBound is a great spell checker for FireFox — a must have if you blog or write email from within web forms.
• Gmail Notifier is a great way to keep tabs on my personal email.
