During development I have to "clear cache" in Firefox all the time in order to make it use the latest version of JavaScript files.
Is there some kind of setting (about:config) to turn off caching completely for JavaScript files? Or, if not, for all files?
Enter "about:config" into the Firefox address bar and set:
browser.cache.disk.enable = false
browser.cache.memory.enable = false
If developing locally, or using HTML5's new manifest attribute you may have to also set the following in about:config -
browser.cache.offline.enable = false
