Font Swap Firefox

Font Swap

Easily preview what websites will look like with any font on Google Fonts.

Features & Capabilities

This extension offers a dropdown list of fonts available on Google Fonts. Cycle through them using the arrow keys or j/k for navigation. Press Enter to mark a favorite, Backspace to remove a font from the main list. These may be reset in the settings tab. Clicking the 🔗 will open a window to a font's corresponding page on Google.

All data is stored locally. Fonts are injected via a simple CSS !important tag (which may not work on a few websites).

Is Font Swap 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.

Font Swap does not require any sensitive permissions.

Risk impact analysis details
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.

Font Swap is recently added, and hasn't been around long enough for us to gather enough data to accurately assess its risk level.
