As a developer I would find it most beneficial if you were to provide 2 settings for the Firefox browsers cache. If we developers were given the option in the settings to register our development urls that were not to be cached and have this seperated from general web browsing caching it would aid in the following. Developers would always know that the data they are viewing is their latest code. General web browsing data would be cached thus keeping browsing of the common sites quick since the browser would be pulling from cache. Reproducible: Always

Easy. Talk to your webmaster - he/she will add the necessary HTTP-header. Or add it in you application itself (in PHP it's done with "header"). PS : you can disable your disk-cache in about:config, by setting browser.disk.cache.enable to false. You can also switch off your memory-cache (browser.memory.cache.enable), but some sites might not work with this.

V/dupe. Probably this would be best implemented as a feature of a tree-based network preference scheme, where you could hang any number of network behaviors (image blocking, cookie management) off part of the DNS tree. I wrote an RFE for it, but it was so long ago, I can't remember the title.
