Records your screen and gives you the file. That is the whole
product.
Why it exists
The leading screen recorder extension has eight million installs and 3.9
stars. Its free plan is ten videos for the lifetime of the account, thirty
minutes each, with a watermark on the export. Search the store for “screen
recorder no watermark” and every result has under two thousand installs: the
demand is stated outright and nobody serves it.
What it does
Whole screen, a single window, or one tab, with system audio and microphone.
Records MP4 directly where the browser supports it, so
there is no conversion step and no WebAssembly encoder to download.
No time limit, and it means it. Chunks are streamed to
disk as they are made rather than piled up in memory. Measured: 105 MB
recorded grew the browser memory by 1.2 MB.
Pause and resume, a countdown, and keyboard shortcuts.
The toolbar icon shows REC while recording, and clears the moment it stops.
Smart zoom — the one paid feature
For a walkthrough, the frame follows your pointer and marks your clicks, so
a viewer eye lands where the work is happening. One purchase, no subscription.
It records a single tab, because that is the only way to know where the pointer
is, and it needs tab capture, which Firefox does not provide.
What it does not do
Not “plays everywhere”. Some browser builds have no AAC encoder and put
Opus audio inside the MP4, which a few players refuse. WebM avoids it.
Where a browser offers no way to stream to disk, the recording is held in
memory until you stop, and the recorder says so on screen.
