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.

Features & Capabilities

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.

Permissions

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.

Works as expected

Saved my day, for some reason it never fetched updated css and js locally and this plugin forced to do it, thank you very much for saving me a few hours of debugging

Regrettably, appears to do nothing at all, leaving FF still as the only major browser it is literally impossible to do javascript development on.

Is No-Cache No-Store for Selected Hosts Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

No-Cache No-Store for Selected Hosts requires a few sensitive permissions. Exercise caution before installing.

Risk impact analysis details

High Allows the extension to observe and analyze traffic in flight for the selected hosts.

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.
