Plutonium Mirror is a Chrome add-on developed by flamewave000. It falls under the category of Browsers and specifically belongs to the subcategory of Add-ons & Tools. This add-on is designed to allow users to define which mirror to use for 5e Tools, a popular online resource for Dungeons & Dragons 5th edition.

With Plutonium Mirror, users have the option to choose between the primary website and two known mirrors for accessing 5e Tools. Additionally, there is a custom setting that enables users to use their own hosted version of 5e Tools. This feature is particularly useful for virtual tabletops (VTTs) like FoundryVTT, where images, links, and content may become inaccessible if the main 5e.tools website experiences downtime.

Plutonium Mirror is a free add-on, available on the Chrome platform. It provides a convenient solution for users who rely on 5e Tools for their D&D gameplay and want to ensure uninterrupted access to the resources it offers.
