766320 - It should be possible to turn off all caching when using the developer tools

Status: RESOLVED DUPLICATE of bug 651888

(DevTools :: General, defect)

Description

[Dan Mosedale (:dmosedale, :dmose)]

Sometimes changes aren't reflected in a web page that I'm working on until it occurs to me to hit shift-reload, which often comes after having wasted some number of minutes chasing down a different theory of the problem (sometimes even shift-reload won't evict, and I need to use the "Clear Recent History dialog).  It would make for a less frustrating development experience if it were possible to turn off all caching in "development mode".

Chrome does this with a single preference on its developer tools panel.  I'm not quite sure what the right UX for Firefox is, given its non-monolithic tools setup.  But the current Chrome setup currently feels less frustrating than the current Firefox setup, so it seems like there's value in attacking this issue.
