Source View
I am a huge fan of Notepad and am serially dying for this option: opening the source code in notepad....exactly how IE does it. It's actmually the only thing they do that I think FF should @ the very least, give an option of, if not make it a standard. Yeah, yeah, yeah, i know no one codes in notepad anymore and that I'm living in the dark ages...but then again, when you're actually writing your code...and having to check over it, not having it finish its tags for you and/or alerting you of coding errors...you *gasp* actually learn! Yes I know I'm trying to be coy about something extremeley miniscule in what we do. So how about this...make it an option? 99% of users will more than likely not even have a clue its there and I KNOW that there are some straight up code nerds that work at mozilla (and I mean that in the most respectful way!) so what tha deally?
Can I have my web & eat it too?
Cheers,

The ViewSourceWith extension
The ViewSourceWith extension may be what you are looking for. You have the option to view source codes in (pretty much) any application including Notepad.
