Features & Capabilities

This very small WebExtension will allow you to inject a custom CSS stylesheet into all sites you visit making you the stylist of your web.

Features include:

  • Inject a custom CSS stylesheet into all websites.
  • Override the injected stylesheet for each host individually.
  • Temporarily toggle functionality for the current tab.
  • See the effects of your changes to the stylesheet while you make them.
The default key combination for toggling functionality for the current tab is ALT+SHIFT+I. Firefox currently lacks a way to change this default combination.

Note that because this is a WebExtension it will not work on sites WebExtensions can't inject CSS into.

Is stylextension 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.

stylextension requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

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.
