Some of the addons that I use which are designed for activities more complex than simply web browsing, such as web development and programming.
Nota dell’autore della raccolta Very advanced editing capabilities for all kinds of web development, be it HTML, PHP, and more. Very nice GUI, as well.
The Web Developer extension adds various web developer tools to the browser.
Nota dell’autore della raccolta Additional web-development options, these aimed at what kinds of web technologies are enabled or disabled.
Permette di visualizzare la barra delle schede in forma di albero
Firecookie is an extension for Firebug that makes possible to view and manage cookies in your browser
Firecookie is part of Firebug since Firebug 1.10
Nota dell’autore della raccolta Adds cookie management support to Firebug. Useful tool when needed, but I mostly leave cookies as-is. Would be particularly useful, though, when developing and testing one's own cookies.
Cool utility for cleaning up a page (for printing or better viewing) as well as for web development. Displays a red rectangle on the element under the mouse -- hit "w" to go wider (get the containing element), then hit other keystrokes to remove, etc
Nota dell’autore della raccolta Allows some very complex and powerful alterations to a page's layout. Also allows permenant changes, I believe, but I mostly use it to manipulate exactly what gets printed out. A little difficult to use, however.
