There have been javascript miners that use GPU, at least on Firefox.

<p>I just came across <a href="https://chrome.google.com/webstore/detail/piobcnfhopbhgpkglmfclghgjahjhalf" rel="nofollow">Rlweb's Bitcoin Generator</a>, a Chrome extension that claims to be the "first google chrome extension creating Bitcoins".</p>

<p>This extension looks quite shady to me, they don't even have a link to their website. Is it a scam?</p>

<p>Would it at least in theory be possible to write a miner application as a browser extension?<br>
With GPU support?</p>

<p><strong>Edit</strong>: For completeness, I found another Chrome extension named <a href="https://chrome.google.com/webstore/detail/dcmbmmhjekejnneeomopbdnfkapnicgk" rel="nofollow">Bitcoin Miner</a>.<br>
This one looks more legit, but it says it's a Flash game. It doesn't really generate bitcoins, or does it?</p>

Is it possible to generate bitcoins with a Google Chrome extension?

(Asked by: username_0 on 2011-09-03)

I just came across [Rlweb's Bitcoin Generator](https://chrome.google.com/webstore/detail/piobcnfhopbhgpkglmfclghgjahjhalf), a Chrome extension that claims to be the "first google chrome extension creating Bitcoins".

This extension looks quite shady to me, they don't even have a link to their website. Is it a scam?

Would it at least in theory be possible to write a miner application as a browser extension?  
With GPU support?

**Edit**: For completeness, I found another Chrome extension named [Bitcoin Miner](https://chrome.google.com/webstore/detail/dcmbmmhjekejnneeomopbdnfkapnicgk).

The Bitcoin Miner extension is simply this [flash game](http://chrazyapps.com/?p=347). Rlweb's Bitcoin Generator does not seem to do anything at the moment. As far as I understand from the description, this should be a client for the [bitp.it](http://www.bitp.it) pool, but it just adds a button to chrome that shows some text.

Mining with your browser is possible. There is an open source [javascript CPU miner](https://github.com/jwhitehorn/jsMiner), but it is [no longer being developed](https://bitcointalk.org/index.php?topic=9042.0) because the difficulty is too high to mine with Javascript. Like username_2 said, other alternatives supporting WebCL and other browser plugins are coming up, but I don't know of any for Google Chrome.
