この拡張機能について
You research across nine tabs, start something in one AI assistant and finish it in another. None of them remember the others, and none of them remember what you read last week.
DoppelBrain is a memory that does. It keeps the pages you actually spent time on, PDFs included, and the AI conversations you had about them, and turns them into something you can search and ask questions of. Your assistants connect over the Model Context Protocol, so whichever one you open already has your context.
A side panel that reads with you. Open it on any page and ask about what is in front of you. It can also fill in forms and click through flows on your behalf, and it always shows you what it is about to do before it does it.
Sensitive sites are filtered before anything is captured. Banking, health, adult, sign-in and webmail domains are on a list built into the extension, so they are excluded on your device, before any network call. You can add any site to that list yourself from the panel, and that choice always wins.
Bring your history in, or do not. You can import the last 90 days from your browser in one step. Nothing is sent until you have seen the list of domains it found and unchecked anything you would rather keep out. The permission for this is optional and only requested if you ask for the import.
Pause any time. One toggle stops capture everywhere. Your data is yours, is never sold, and is never used for advertising.

Firefox support is new. The sidebar, capture, history import and the assistant are all working, and we test each release on current Firefox and on the 128 ESR floor. If something behaves differently here than you expect, please write to support@doppelbrain.ai rather than leaving it in a review — we read every message and Firefox reports get priority right now.
