The 30,000 pixel limit is a consequence of the Firefox APIs that Page Saver uses to capture images of webpages. But they should be stitched together seamlessly. I am sorry for that problem. We have received a few reports of this problem recently but not everyone is experiencing it. Please contact us via email to support@pearlcrescent.com so we can debug the problem. Providing info about your environment (operating system, Firefox version, etc.) will help us.
