Since I do not live in a English-speaking country, my computers do not have the standard US or UK keyboard layout and some of the characters the generator puts into the secure password are not present on keyboards in my country. This makes it unnecessarily difficult to input my passwords in devices where I am not logged in with my Mozilla account, and while I could easily avoid the problem by manually changing those characters on password creation, I believe it would be simpler if somewhere in the options the user could change the selection of character that can be chosen when creating the password. This also makes it easier for sites that have restrictions on characters.
