I'm unable to update Mozilla Firefox using apt due to the following error:

E: Failed to fetch https://packages.mozilla.org/apt/dists/mozilla/main/binary-amd64/Packages 400 Bad Request [IP: 34.160.78.70 443]

While troubleshooting, I found that the request does return the package list, but with a 400 Bad Request status, which causes apt to fail.

I need step by step setting up Protonmail to Thunderbird. I had this set up before but it stopped working. I know my emails and their corresponding passwords are good because I have access on the web. I am getting "unable to log in at server. Probably wrong configuration, username or password" When I try to put my newest address in. Not only do I know that my passwords for my emails are correct, but I also have a copy of the screenshot of the configurations from when I set it up before: Imap, hostname, port, username, password security. I use this to double check when I go into the Manual configuration account setup. The other error I get is "login to server 127.0.0.1 with username Grammy14@proton.me failed." This email had been working just fine until April 19. I love Thunderbird's set up when it works, and I donate regularly. I have been working on this for a week now. It would be great to get live help. I would gladly pay for the help. It would be nice have that option.

Hi, Trying to install Extension List Dumper 2 from file Thunderbird Setup 137.0.2.exe. Using Thunderbird 128.9.2esr (64-bit) Release notes

Where to get?

Thanks.

Hi All,

I have a number of computers that I would like to have configured identically, including Firefox's extensions. Is there a mechanism that I could use to automatically install a list of extensions on my (linux, windows) computers?

TIA, Mike.

How do Import Emails, Email Folders, Calendar and Contacts from Outlook for Mac into Thunderbird? I have exported my data to an Outlook For Mac Archive.olm, but none of the import options recognize the file.

I rarely stop thunderbird, running your 137.0.2 atm because debians 128 turned into a crash-o-matic while downoading my inbox from shentel.net several months ago. Your help menu sometimes doesn't display versions. But everytime I restart thunderbird, I have to setup my local folders and msg filters from scratch. I am subbed to quite a few lists, probably 30 or more and it usually takes around 70 msg filters to get it all working. Why can't there be continuity? Or, how can I recover my local folders and msdg filter?

Thank you. Cheers Gene, CET

Добрый день Есть ли возможность установить плагин .xpi в mozilla через cmd. AltLinux. Конечно я уже прочел статьи существующие. Не сработали рекомендации. Можно ли сделать вывод что Firefox 128.0 ESR не поддерживает установку плагинов через cmd? Если да, то можем ли мы сослаться на официальный ответ firefox ? Благодарю за рекомендации.

Hello

I tried upgrading from Ubuntu 22.04 to 24.04 but the update aborted at the end because of an issue with the Thunderbird - I think the transition to snap.

Now the Software updater says:

"The package system is broken. The following packages have unmet dependencies: thunderbird-locale-en: Depends: thunderbird (>= 2:1snap1-0ubuntu3) but 1:115.18.0+build1-0ubuntu0.22.04.1 is installed"

And the Synaptic package manager says:

"Transitional package - thunderbird-locale-en -> thunderbird snap This is a transitional dummy package. It can safely be removed. thunderbird-locale-en is now replaced by the thunderbird snap."

Thunderbird is running fine, as version 115.18.0 (esr channel, deb installation, according to what I see in the snapstore).

I want to upgrade to Ubuntu 24.04 and keep my well functioning Thunderbird! But I have no idea what to do.

Thanks for any help!

Why hasn't Firefox updated since April 15? (It's currently the 28th). Things are lagging, primarily on You Tube (for the last 4 or more days), and normally updates don't leave as much time in between updates. Anyone know what's going on? Will it ever update or do I need to leave for another browser?

AFTER 137.0.2 EVERY TIME I START FF ALL MY PREVIOUS TABS ARE GONE AND I BACK TO THE TOUR SCREEN. ANYONE KNOW HOW TO FIX THIS, BESIDES SWITCHING TO ANOTHER BROWSER?
