Cat Gatekeeper for Firefox: Current Status
Firefox and Mozilla users want the same cat overlay, but Cat Gatekeeper is still Chrome-first while Firefox support remains in progress.
Cat Gatekeeper Firefox and Cat Gatekeeper Mozilla status
Cat Gatekeeper is not available as a public Firefox Add-ons release today. Mozilla support is still marked as coming soon or in progress, while the Chrome extension is already available.
That means Chrome is still the reliable way to get the real Cat Gatekeeper experience today. A live-looking mirror, a missing add-on page, or a similar name is not enough proof that the Firefox version has launched.
Why the status matters
Browser extensions can move through review, private testing, or temporary listing states before they are truly available. For a tool that sits on top of social sites, you should be careful about installing lookalike extensions that ask for broad page access.
Watch the official project page, the GitHub repository, and the creator’s X account for release news. When Cat Gatekeeper for Firefox is ready, those channels are more trustworthy than random extension pages or snippets.
What to use now
Use the Cat Gatekeeper Chrome extension if you want the cat overlay now. If Firefox is your main browser, bookmark the project and wait for the Mozilla release instead of installing an unrelated blocker with the same idea.
