Translation - metamask crashes the Firefox browser when I try to install it, tried several times, crashes exactly when I fill in the part on the attached screenshot and move on

This is the Thunderbird Forum for the email client. You need to post this in the relevant Firefox Forum

This is the Thunderbird forum. I think you may have wanted the one for Firefox.

I have no idea either. But I can transfer this to the Firefox forum and I will.

Be aware that this is supposed to be a family friendly site and language such as you are using,  whilst perhaps welcome in you local bar, will not be tolerated by the folk in the Firefox forum.

I think I need to point out that this metamask (I had to google it) appears to be an add-on for Firefox https://addons.mozilla.org/en-US/firefox/addon/ether-metamask/

It has always been Mozilla policy that add-on authors support their add-ons. To that end the download page contains links to a support site and a support email address.(Neither at mozilla.org) Perhaps you need to pursue the appropriate support venue for your issue. Then you would not have had to put up with folk pointing out you are in the wrong place and they can not help you because it is an add-on problem.

I have transferred this to the Italian Firefox forum as it appears the original request was in Italian.
