No-Cache No-Store for Selected Hosts
Reloading doesn't update your CSS any more? Bypass Firefox's aggressive caching of CSS (and optionally other content) during development. Use the button on the Page Actions menu to grant new host permissions for blocking.
What is No-Cache No-Store for Selected Hosts?
No-Cache No-Store for Selected Hosts is a Firefox add-on that allows you to bypass Firefox's aggressive caching of CSS files during development. It provides a button on the Page Actions menu to grant new host permissions for blocking. With this add-on, you can improve the efficiency of CSS updates without the need for constant refreshing.
Firefox 79+ no longer revalidates cached CSS files against the server to pick up updates on a standard reload (F5 or Ctrl+r/Command+r). Use this extension to disabling CSS caching so you don't need to use Ctrl+F5 or Ctrl+Shift+r/Command+Shift+r each time.
It would be more convenient if you didn't need to grant permission on a site-by-site basis, but I hope this design makes it easier to trust the extension, since it can only intercept responses from servers that you've allowed yourself.
No-Cache No-Store for Selected Hosts may not be safe to use and it requires some risky permissions. Exercise caution when installing this add-on. Review carefully before installing.
No-Cache No-Store for Selected Hosts has earned a fairly good reputation and likely can be trusted.
