PS : For the record and for once reddit was hepful. # I will assume Tutanota has probably made the choice to remove it. # That's right, now the previous adress : "" doesn't seem to exist (at all). # Which can be reach only at this new adress : "" You can either scroll down until you find mailto listed there or enter. Firefox lists all known file types link types on the page. There you need to switch to the applications tab. # At this moment, the notification has vanished on the new website of Tutanota. Firefox users need to tap on the Alt-key on the keyboard and select Tools > Options from the menu bar that opens up after they do. So thank you because I had found this solution : lockPref("",false) The only way to stop mailto: links from opening in a desktop mail client is the use of third party applications (global), browser settings (Firefox). # Just recopy this example inside the url(chrome://browser/content/browser.xhtml)

# How to remove the button close on every tabs ? And no I wasn't able to find another solution even with the file " userChrome.css"īut at least, it could be reactivate : lockPref("",true) Another little bad news, because Mozilla has made another change that's why now it didn't work with Firefox-v70.Īs you can probably guess, apparently the file " userContent.css" can't rectify this trouble anymore.
