Unfortunately not, and not for any rational reason. It's the same reason I don't buy iPhone apps: because the vast majority are free.<p>There's an implicit valuation when one uses the term "chrome extension". When analyzing how much it is worth <i>to me</i>, I subconsciously compare it to other Chrome extensions, not other bits of code. I might be perfectly happy to pay for MS Office, even when OpenOffice is free, simply because most productivity applications command a premium. It seems <i>right</i> to pay for it. Even a $0.99 fee for a chrome extension or, for that matter, an iPhone app, presents a significant enough disincentive that I likely won't purchase it. In fact, I've <i>never</i> paid for any piece of software that wasn't a game or preloaded on my system.<p>Now, I'm not everybody. Certainly, there will be those out there who <i>would</i> be willing to pay for a Chrome extension, but I wouldn't count on them being the majority. If you do decide to charge for it, make sure that you set a value that accurately reflects what <i>you</i> feel it is worth, rather than what might entice people to use it. A $0.99 fee is high enough to stop most people from paying, while low enough to be pointless for you. Consider $9.99. I doubt that only 10% of the people who would pay $1 would pay $10. If I'm right, you make more money by charging more.<p>As to your idea, keep in mind that Chrome is still a browser with a small market share. If you really do want to make your idea pay, consider releasing a version for FF, IE9, Safari, etc. Or just make a website.
