  • I changed my password of gmail e-mail. How can I change the password used by Thunderbird to connect to gmail.

    I changed the password used to access my gmail account. Thunderbird still uses the old password to access the account. How can I change the password that is using Thunderbird. The last time this happened I ended up creating a new account to Thunderbird for gmail. Create the new Thunderbird account at least let me enter the new password. I don't really want to have three accounts of Thunderbird for the same gmail account.

    Please do not respond with suggestions on using password manager. I do not use it and do not want to start. I looked, and none of my Thunderbird passwords are displayed here. All I want to do is change the password in Thunderbird. If Thunderbird does not have a feature that allows you to change passwords, should be added.

    The link posted by Christ1 gives WRONG directions. In Thunderbird 24.4.0, is:
    Tools, Options, security, passwords, saved passwords

    Admittedly, in fact, you want that he SHOWS you the passwords, and then you can delete them.
    Once fact you check for mail, it will tell you, it didn't, and then you have the option to enter a new password.
    MUCH too complicated. Time to put the password and the ability to change, in the e-mail account options.

    I want to be part of this mozilla firefox support community forum. That's what I call it: a help forum. but it's sorta a little ironic, don't you think (?) that I'm not able to change my password, here, on this forum.

    do you know how I can change my password for THIS website in mozilla firefox help? There is no link that takes me to this particular thing. It is not available in all the links that are related to my profile. If I can not log on in the future, what good is to join?

    I am also very grateful with the rigor that you put into your response, because it gives me the way to mark this issue as being resolved, too. Be healthy and happy!

  • How can I change my password for connection of Firefox? (Not the master password for the Firefox links saves itself)

    (1) how can I change my password for connection of Firefox? (Not my main password for things Firefox stores)
    (2) how can I change my password for connection of Thunderbird? (Not my master
    password for things Thunderbird stores)
    Just answer (Email removed by mod)

    You don't have to log in to Firefox. Firefox is just a browser, such as Internet Explorer. Everything you have to do is double-click it and open it. It's like Internet Explorer. If you have some sort of password extension protecting your Firefox, it's different and you need to contact the developer of the extension.

    IF you are referring to your password for your AppleID, then you can go to this page; https://appleid.Apple.com/

    Once there, you want to go to the Security section. Then, you click on change password. Then enter your current password, and then enter a new password and confirm the new password. Then click on change password. We'll then spend your AppleID password. If it is the password you speak when you try to download apps.

  • How can I change the password for wifi on Apple TV 4?

    I changed my password for wifi and when I go into settings wifi on Apple TV, the network is there, but when I click on the name of the network, nothing happens.  He asks me the password.  It was a half hour and it still does nothing.  I tried to do a system restart and still nothing.  How can I change the password so I can reconnect to my network?  Is there a way to tell him to forget the network as on my iPad and iPhone?

    (btw, I changed the password to "*".)  I feel like the punchline of a cosmic joke.   )

    Do a reset.

    Also, not a good idea to post your password on a public forum
