Periodically my BCC function suddenly quits working in Thunderbird. This morning it has totally failed and I cannot BCC to my own email in a single test email. Yesterday it was working great and has usually worked great. A couple of months ago I had this same failure and after some hours had passed, and it suddenly began working well again. This is the error message for today for all BCC: Delivery has failed to these recipients or groups: annfriday2021@outlook.com Your message wasn't delivered because the recipient's email provider rejected it. Update: I tested it just now and it will BCC to all of my TB mail groups except for one group which I have not had problems with in the past. However, an hour ago the BCC was not working for any of my TB mail groups, nor for a single BCC test email to myself. Thanks

There is some worst problem with Firefox for android's management of storage data. When I click on translate a page, it download some pack of the source/target languages and keeps it in app's data permanently. The language also does not show as been downloaded in the translate setting section. Unwantedly firefox consumes persistent storage only for just after we randomly to translate a page from a random language and firefox android download unwanted languge's pack and event does not show in downloaded languages. No way to clean the storage apark from "clear data" which we do not want to do ! Same happens when you have an incognito session with multiple tabs open, and the system closes Firefox when you open some other apps. Firefox loses track of the "potentially to be deleted" data. Firefox data increased forever after such a Hard closed session.(in low RAM device 3-4GB). No other option except to Clear Firefox's data!

I receive emails sent to plus addresses. eg user+text@gmail.com . In my address book, I have an entry that has a display name for the email user+text@gmail.com , but it is not displayed in the email view. Other emails that are not plus addresses do correctly get the display name and display it.

I have tried switching the setting for display names, but it does not matter how it is set. It does not display the display name.

I have no idea what passwords from . csv.files are or where to find them on my Asus LinuxMint laptop?

 The only password and username that i entered into my LinuxLaptop  are the only usernames and passwords

that I've entered into my new computer. I've also entered my google Chrome username and password to set up my Thunderbird email service. I never wanted to sync all my usernames and passwords in my Acer laptop computer because I felt that that made it too simple for a hacker to access all of my personal Information and access to accounts. Mozilla Firefox wants a password for csv files or tsv files or HTML files ? I don' know what any of these files are or where to go to to find them or the passwords for these files. I just want to successfully transfer all of my Favorates folders and files then all my Documents and picture files to my new computer. I'm a Photography artist, Graphic Designer,abstract painter, and creative writer. I can't move forward in my creative pursuits without completing these tasks. Thanks very much for your help and information. I'm soon to be 80 years old and not a very good keypuncher on a computer. I'm happy to leave Microsoft Windows and Google behind but Linux Mint is all new to me.

I have deleted my profile and reinstalled Firefox, updated graphics driver to the latest version, and toggled hardware acceleration on and off. Nothing helps.

I have been very happy using Thunderbird to access the email account of my volunteer position, I have always used the Email, Calendar and Task feature. I have the automatic updates setup on Thunderbird and until recently had no issues at all, until the last update. When Thunderbird first started with the newest update the calendar details were visible and then Thunderbird disabled the Calendar and Task and no matter how many time I click the Enable button or edit the properties to say enable Thunderbird immeadiately sets it back to Disabled. I have uninstalled Thunderbird, and relinstalled an older version - problem there doesn't seem to be a profile to match, so I just kept manually updating Thunderbird to a newer update until the absolute latest, but there were issues with the profiles again. I then uninstalled and installed the latest version available directly from the website and was able to get another profile to work for my local folders - I had saved some docs locally to conserve disk space on the email server. But no matter what I cannot get the calendar to work at all. There are no posts that cover this particular situation. Any idea how to fix this???? Thank you to anyone that offers assistance with this issue.

I'm unable to login to account.apple.com on my laptop which is running Ubuntu 24.04.3 LTS.

I've launched Firefox using the `-p` option, created a new profile and then navigated to https://account.apple.com/sign-in and tried to login. I've attached a screenshot of the error message.

I had tried multiple things on my default profile, even troubleshoot mode, but I couldn't get it. I even tried useragent switcher to no avail.

I can login to the site using Chromium.

What else can I try?

Hi, I use Thunderbird for Android Beta 12.0b6 and I have the following problems: 1. Most of the emails I deleted from the notification shade still show in my inbox when opening the app.

2. Since the last update, the gestures work poorly, I have to swipe 2 or 3 times in order to delete an email.

Please have a look into it when you have the time. Thanks

Hi.,

On or about Aug. 11, 2025 my email when it comes automatically from Optimum suddenly it's a more computer language email message. For me, it's very difficult to figure it out and it's VERY long. I copied and pasted on line to give you an idea. Here it is: This is a multi-part message in MIME format

just checked my Optimum email box and the messages are in their regular format, so somehow just recently when Thunderbird downloads the messages it gets presented in computer language and the subject and provider are all blank.

Please tell me what I should do.

  Thank you.

The cursor changes from the Hand, Caret back to a normal cursor when hovering. Also sometimes the cursor disappears entirely. Moving the mouse temporarily makes it visible again. The latter is especially annoying and it occurs on most websites including even the Firefox Add-on site. Refreshing the Which suggests it is not related add-ons (at least most of them anyway).

I have a different browser with the same user.js (BetterFox) and same chrome.css. However, I was not able to replicate it there. Maybe I need to have open many dozens of tabs. No issues with my browser otherwise, performance or memory. Anybody else have this issue or can help troubleshoot and find the cause?
