Tab through textboxes on a page instead of all focusable content

[jacinto27]

I don't know if this is implemented on any other browser, or if its implementable at all. But often times I switch between tabs using shortcuts like Ctrl+Pageup/down or Ctrl+Number and am (slightly) annoyed when I have to tab through the entire page just to get to the textbox I need.

Is it possible to make a custom keyboard shortcut (like Ctrl+/ or Ctrl+Shift+Tab) on firefox that focuses on either a primary textbox (type=search on sites like gmail) or maybe just tabs through all visible (or present) input fields? that way it improves accesibility dramatically for users without a mouse like me, and would be an innovation that (I don't think) any other browser has. A lot of times browsing is just about reading, and typing, almost on a site with a search box.

It's probably possible to implement this with a script on some of those scripting extensions out there since it's  (seemingly) relatively simple (to do in JS), but, is it possible? is it viable? am I alone in this usecase? Should I open a bug report about it? I'd like some feedback if possible.

Thanks
