A screen recorder for Firefox.
Firefox supports `getDisplayMedia` — Screendog uses it directly without an add-on. Recording works the same as in Chrome or Edge; the resulting WebM is compatible with every tracker we file into.
No add-on required
Firefox's built-in Screen Capture API does the work. There is no XPI to install, no Mozilla review queue, no add-on update prompts.
Codec notes
Firefox produces VP8 or VP9 WebM depending on system codecs. All five supported filers (Linear, GitHub, Notion, Slack, Jira) play these formats inline.
Frequently asked
System audio on Firefox?
System audio capture support in Firefox is more limited than Chromium. Microphone capture works everywhere.
