Hoardy-Web Firefox

Hoardy-Web

Passively capture, archive, and hoard your web browsing history, including the contents of the pages you visit, for later offline viewing, replay, mirroring, data scraping, and/or indexing. Low memory footprint, lots of configuration options.

Features & Capabilities

Hoardy-Web passively captures and collects dumps of HTTP requests and responses as you browse the web, and then archives them using one or more of the following methods:

  • by saving them into your browser’s local storage, which is the default;
  • by submitting them to your own private archiving server via HTTP, like
  • by generating fake-Downloads containing bundles of those dumps, making your browser simply save them to your Downloads directory.
Hoardy-Web produces dumps in a very simple, yet efficient, WRR file format (also on GitHub).

Moreover, Hoardy-Web implements:

  • UI indicators that help in ensuring good and complete website captures,
  • optional post-capture machinery that helps in archiving only select subsets of captured data;
  • archival+replay integration when used in combination with an advanced archiving+replay server like hoardy-web serve (also on GitHub);
  • capture of DOM snapshots;
  • inspection of captured HTTP traffic, similar to browser’s own Network Monitor (except browser-wise, i.e., it can capture HTTP requests even when a page generates them when its tab/window closes; which a surprising number of websites does to prevent their web traffic from being inspected with Network Monitor);
  • some generally useful web browsing features (like per-tab Work offline mode).
In other words, this extension implements an in-browser half of your own personal private passive Wayback Machine that archives everything you see, including HTTP POST requests and responses (e.g. answer pages of web search engines), as well as most other HTTP-level data (AJAX, JSON RPC, etc).

For more information see project’s documentation (also on GitHub) and extension’s Help page (also on GitHub) (also distributed with the extension itself, available via the “Help” button from its popup UI), especially the “Frequently Asked Questions” section there (also on GitHub).

Also, note that:

  • Hoardy-Web DOES NOT send any of your captured web browsing data anywhere, unless you explicitly configure it to do so.
  • Hoardy-Web DOES NOT send any telemetry anywhere.
  • Both of the above statements will apply to all future versions of Hoardy-Web.
Hoardy-Web was previously known as “Personal Private Passive Web Archive” aka pWebArc.

Is Hoardy-Web 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.

Hoardy-Web 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.

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