Thank you for your feedback. I don't believe the capture popup significantly degrades performance, but I agree that it does not provide the most elegant user experience. As for the page restrictions, currently Page Saver WE is prevented from injecting its page capture JavaScript code into some pages. We will investigate why Mozilla's capture tool is less restricted. Finally, thank you for the suggestion about capturing all open tabs in a window. Please email us at support@pearlcrescent.com if you are willing to tell us more about how such a feature should work and how you would use it.
