Adds commentary and keyboard navigation to the pages of Homestuck.com stories. DEPRECATED as of 2021 due to Homestuck.com's state.
Homestuck Companion displays all existing commentary for Homestuck (up to the end of Disc 2, two thirds through ACT 5 ACT 2), complete commentary for Problem Sleuth and enables keyboard navigation for all adventures on the site.
As of 5/22/2021, this extension has been deprecated due to Homestuck.com's state of decay, though it's been updated to work indefinitely without requiring a server. In the future, this extension will be ported to Bambosh's Homestuck Unofficial Collection (google it).
To use: just go to a supported URL like "https://www.homestuck.com/problem-sleuth/10" or "https://www.homestuck.com/story/513" and behold the commentary. Use the extension options in order to disable commentary display, if you just want the controls.
Keyboard controls (arrow keys for changing pages, right ctrl key for opening/closing pesterlogs) work on every page of every adventure except Bard Quest.
