FAQ
Which browsers do you support?
Chrome, Firefox and Edge. The Basic package covers Chrome and Edge. Standard and Premium add Firefox.
Can you publish the extension to the Chrome Web Store for me?
Yes, with the Premium package. You’ll need your own developer account, and Chrome’s review time is outside my control.
Will I get the source code?
Yes, with the Standard and Premium packages. Basic delivers the working extension only.
Can you fix or add features to an extension I already have?
Yes. Message me first with the details so I can quote you correctly.
Can you build an extension that scrapes any website?
In most cases, yes. Some sites block automated access or forbid it in their terms, so I’ll check feasibility with you before starting.
