Hello,

I have to add the Password every time I open Thunderbird because I removed the Password myself after I read this:

<<<< ThundaMike Mozilla Staff 7/28/25, 9:15 PM more options Sounds like you are almost there.

Building off what @david said above, try this:

In Thunderbird, go to Settings > Privacy & Security.

Scroll down to the Passwords section and click Saved Passwords….

Find your email account in the list and remove the saved password.

Restart Thunderbird.

When prompted, enter your new password. >>>

My doing this it removed the .twc password Log In totally in that Settings. I do not see the "my twc.com" in the settings of Tools, Privacy & Security, then Saved Passwords in the list, I only see the Hotmail account settings I have in Thunderbird. Removing it like ThundaMike wrote really removed all the TWC Password and Information.

Can someone help me restoring or re-enter my Mozilla Thunderbird info back into Tools, Privacy & Security, then Saved Passwords so I do not have to type in the Password every time I open Thunderbird.

Thank you so much for your time and efforts I truly appreciate it.

Search drop-down list has first Item with blue pushpin symbol next to it and the next item has a blue star symbol next to it. The rest do not have any symbols next to them. I'm using Windows 11, Firefox. and DuckDuckGo.

Currently using android 15, can i hide hide this in firefox's setting? If not, please mozilla, add an option to hide the background behind the bar, it's sucks. I did research and found that it is an app issue and not an OS issue, thanks

I have been using Thunderbird Mail for many years and have been satisfied with it. I followed the recommendation to upgrade to version 145. Then disaster struck: the previous version was completely deleted, including all email accounts and address books. How is that possible?

Hello Firefox Support Team,

Thank you for providing such an excellent browser, free of charge and without advertisements.

I am experiencing an issue on my Samsung J5 running Android 5. When I try to set Firefox as the default browser, I am redirected to an information page. While helpful, it does not mention that Firefox cannot be set as the default browser on Android versions below 8.

It would be clearer if this limitation were explicitly stated on that page.

Thank you for your attention, and best regards to the entire Firefox team.

Hi there,

I've recently made the move to Windows 11, and since then I've been having loads of issues with firefox hanging and crashing. I've been able to correct the issue for about a week at a time by clearing my startup cache, but I did so incorrectly recently and it corrupted my profile, resulting in the need to create a new default one.

I'm able to launch firefox okay now, but when I try to sync my bookmarks and settings, firefox freezes every time immediately upon login. Is there a way I can sync my settings without using the firefox UI in order to circumvent the crashing issues present in the UI?

I recently upgraded from Windows 10 to Windows 11. I was under the impression that my bookmarks would be saved to my Mozilla account and I could then log in on the new computer and the bookmarks would come over also. Is this accurate or will I have to go about recovering my bookmarks a different way?

As of now when I log into Mozilla I get a message at the top saying "The bookmarks and history system will not be functional because one of Firefox's files is in use by another application. I clicked Learn more and tried the troubleshooting options, but no luck in fixing the message or issue. Thanks for your help.

I updated Firefox to 145.0 this morning, and after Firefox had restarted, it had lost all bookmarks and the bookmarks toolbar. I have spent all day following links to correct the problem and got nowhere. I have restarted Windows and Firefox countless times - no change. I've even tried reinstalling Firefox over the existing version. If I go to bookmarks > manage bookmarks > restore and backup, sometimes that will load, others not. When it does load, it fails to find a file to restore from. 10 years of bookmarks, links & research vanished.

Can someone please provide a solution (preferably in Layman's terms) to this??

In Thunderbird's Settings under "Language & fonts, Choose the languages used to display menus, messages, and notifications from Thunderbird" I have selected Danish and English. Now I would like to remove English, because my folder pane is displayed in English, even though I have selected Danish as the first language (I am from Denmark). But I cannot remove English in Settings, only move Danish or English up or down. I cannot click on the Remove check mark, neither for Danish nor English. Does anyone know why?

I have an email account with BlueHost, which also hosts my web domain. A couple weeks ago I stopped receiving emails and contacted BlueHost tech support. The agent had no clue why I wasn't receiving email. She said "Can you please click on acocunt actions and remove the account and re-addd it. [sic]" I did that, and I was again able to receive emails. But then all my old emails -- sent and received -- had disappeared. BlueHost was able to restore my Inbox emails back to May 19, but was not able to recover any Sent emails. I have a backup of my Thunderbird directory from April, but would like to recover all of my old emails, which apparently still exist because my current Thunderbird Profiles directory contains files corresponding to deleted email folders. For example, my Inbox had a subfolder -- call it ABC -- that was deleted and is no longer visible in my Inbox, but I can find files ABC (no extension) and ABC.msf in my Inbox.sbd folder. My Sent.sbd folder also contains files ABC and ABC.msf. These folders are in C:\Users\aaa\AppData\Roaming\Thunderbird\Profiles\aaa.default\Mail\mail.aaa.com (with "aaa" representing my personal identifiers). mail.aaa.com contains files Inbox, Inbox.msf, Sent, and Sent.msf, which seem to contain my old emails. (Inbox is 132,151 KB and Sent is 289,829 KB, and the file dates are from a couple weeks ago, when I removed and re-added the email account.)

Is there a way that I can recover the old emails?
