Just happen to stumble upon what I think would be a potentially great extension (amongst others) for Web Designers/Developers—IETab. Its slick that you can open/view a webpage in IE but embedded in a Firefox tab. That, and you can run “Windows update from Firefox!”
Other extensions that are on top of my list and use currently would be:
- DOM Inspector (installed by default)
- Web Developer
- VRSC (View Rendered Source Chart)
- HTML Validator (based on Tidy)
Hope those help. Happy extending!
PS. Any other great extensions? Let me know… I’m always looking for something that can make things easier, as well as interesting.
Additional ones to look at…
