Same issue as everyone else. You *cannot* throw a splash screen in my face every time a page fails to load properly. Have some respect for your user base - if someone is familiar with the Wayback Machine and chooses to install this extension, chances are they know how to navigate to the archive for dead pages via the widget! Please add a toggle. This is an issue I would have expected the Archive Team of all groups to be savvy to.
My primary reason for downloading was to be able to quickly save websites and contribute to the archive. While this extension makes that slightly more convenient, I would recommend that anyone seeking similar functionality just memorize this to prepend to the address of whichever page you want to save: "https://web.archive.org/save/". If you're more interested in the other function, you can instead prepend "https://web.archive.org/web/*/".
Other people have suggested that the page-down screens be converted into banners, and while this would be a huge improvement, I would really like to be able to disable all popups regardless of "intrusiveness." Again, this seems like something you guys would be sensitive to! I can't understand why it's designed this way.
