YES 1.7.14 WORKS! I’m impressed and my Firefox-loving client will be thankful.

Yes, Firefox ??
Thanks for getting back. I’m not totally sure how to do what you suggest…do I need to deactivate and uninstall the plugin i have … and then download the next version from github as a zip (and install)? I’ll need to re-do my plugin settings/customizations? There aren’t a lot.

I have this same issue. Firefox browser, version 87.0 on this page. Print-o-matic works beautifully (thank you) on every other browser I’ve tested. On firefox tho– the printable page just flashes open for a second and then disappears like nothing happened. I tried changing firefox’s default pop up blockers, etc, but couldn’t get results.
