When you print from Gmail, does the site normally opens a PDF in a new tab, or does it open a print-formatted web page in a new tab? To give ''mail.google''.''com'' permission to open pop-up windows, try this: (1) While viewing the page, call up the Page Info dialog using one of these methods: * Ctrl+i (for Mac, Command+i) * (menu bar) Tools > Page Info * click the lock icon in the address bar, on the drop-down click the "Connection Secure >" button, then at the bottom click "More Information" (2) When the dialog comes up, click the Permission icon at the top to show that panel. (3) Scroll down to "Open pop-up windows" (4) Uncheck the "Use default" box, and then select '''Allow''' to let scripts on the site open new tabs. Any improvement?
