File Title doesn't work. A shame, I liked the idea myself.
Download Embedded - needed an install.js, a regular contents.rdf, and a skin contents.rdf. It works,
however, when installed, the Download Manager, Error Console (JavaScript Console) and the Java Console can't be called anymore. Even though when you want to download something through the extension, it pops open both a save file dialog, and the Download Manager.
Performancing - needed an install.js, a regular contents.rdf, a skin contents.rdf, and a contents.rdf for each locale. Seems to work fine, but I haven't tested it much.
View Formatted Source = ViewSourceWith ?
No.
The link you had provided led to ViewSourceWith, though. Anyway,
found it. Will hack it later tonight.
(404 error link here)
Grr, damn case-sensitive server. Fixed.
By the way, I just noticed that linked from here, it doesn't lead to an install dialog. I hope it doesn't confuse anyone...
