Extraneous Firefox

Extraneous

Bloat for Invidious: DeArrow integration, watched video markers, filters and more.

Features & Capabilities

A WebExtension for Invidious, written in TypeScript using Deno.

Modules Each module can be toggled and configured individually.

Watched

  • Keeps track of videos you've watched and highlights them using a user-defined CSS filter
  • Video IDs are stored in your browser's local storage

Hide Videos

  • Set a minimum duration for videos to be shown
  • Set a regular expression to filter out videos with unwanted titles

DeArrow

  • Reliably retrieves clickbait-free thumbnails and titles from DeArrow.
  • Opt-in to show untrusted titles.
  • Option to hide thumbnails until replacements are fetched.
  • Option to highlight replaced titles

Additional Links

  • Display prefilled cobalt.tools download link in sidebar

Why access to all sites? With Invidious instances being community-hosted, it's not feasible to manually add instances to the list of allowed sites and remain up-to-date. Instead, Extraneous runs on all pages, checking if they are an Invidious page. Unless a site is trying to look like an Invidious instance to the add-on, Extraneous code should not run on unrelated sites beyond this check.

Is Extraneous 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.

Extraneous requires a few sensitive permissions. Exercise caution before installing.

Risk impact analysis details
  • Critical Allows access to all websites, posing a significant security risk as it can monitor and modify data from any visited site.
  • High ******* ******* **** *** ****** ***** *** ***** ** ******* **** ********* ********* ** * *********** *****
  • Low ******* ****** ** *** ********* ******** **********
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.

Extraneous is probably trust-worthy. Prefer other publishers if available. Exercise caution when installing this add-on.
