Features & Capabilities

Cache Companion helps geocachers track progress on grid-based challenges without leaving geocaching.com.

Jasmer Challenge — find a cache hidden in every month since May 2000. Cache Companion shows your status next to the hidden date on every cache page and map preview.

Fizzy Challenge — find a cache for every Difficulty/Terrain combination (9×9 grid). Your status appears next to the D/T rating on cache pages.

Dashboard — a full year×month grid for Jasmer and a 9×9 D/T grid for Fizzy, both with clickable cells that open the map filtered to caches you still need.

Import — load your My Finds Pocket Query GPX file to populate all data locally. Nothing leaves your browser.

Toggle challenges on or off individually. Supports light and dark mode.

Is Cache Companion 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.

Cache Companion requires a few sensitive permissions. 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.

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