https://packages.mozilla.org/apt leads to 404, not a Debian software repository / archive.

Step 4 (is broken)

Next, add the Mozilla APT repository to your sources list:

echo "deb [signed-by=/etc/apt/keyrings/packages.mozilla.org.asc] https://packages.mozilla.org/apt mozilla main" | sudo tee -a /etc/apt/sources.list.d/mozilla.list > /dev/null

Just as the title goes. I've been using Mozilla Firefox on desktop since 2005. The best hands down browser ever. I started using Firefox on android back in 2019.

I still love the android version, but my only problem with it is tabs. They stay open constantly. In the desktop application you close out and all the tabs close. In the android version I swipe up and there still there next time I load in. I don't like this at all. Unless I quit out of Firefox from the submenu, the tabs will stay open indefinitely.

I was hoping Mozilla could add an option to auto close tabs in 6 hours or something like that. Or close out tabs when I swipe up in android.

I have moved about 20 friends and family to Firefox and it's always going to be Firefox from now on. You guys rock!

What has happened to the "More actions" menu button - the one that normally is in the upper left corner of windows (see the attached image)?

I have just installed a new PC, with Debian 12 and KDE (plasma 5.27.5); the other windows have this menu button, but not Firefox and Thunderbird. Is there a way to get it back, eg by moving the menu bar out of the title bar and back to where it used to be?

Hello, I just finished installing all my tools and such on my new laptop (Dell 7780). The laptop is Win 11 Pro with all updates for 24H2. I installed Thunderbird (128.3.2esr 64bit). I have used Thunderbird for over 20 years or so. I know how to move profiles, etc. Well, I moved my profiles from old laptop to new laptop and everything was working fine.

Today, I tried to go into Thunderbird Settings (NOT Account Settings). if I go through the menu Tools \ Settings. Nothing happens. Use the ||| on the taskbar, NOTHING HAPPENS. Open "Account Settings" and go down to * Thunderbird Settings, NOTHING HAPPENS. Tried using Troubleshooting and restart with no change.

I also reverted back to the original Profile that was the default when it installed. I then imported from my other profile saved off. Same deal, cannot open Settings. (Tried before Import and after).

What have I done wrong? What can I try and massage to get the window to show?

Thanks,

Joe

I just updated Firefox to version 135.0 on my mobile and now I get this really annoying thing:

Everytime I open a tab to go on the YouTube website, it asks me if I want to leave Firefox and use the YouTube app. Every single time. And it even launched it once without asking me.

I don't want to use the YouTube app, how can I make this stop?

Have a good day!

Where did this strange language come from? I synced my laptop to my Android phone and somehow this language started appearing English and another language I can't identify.

Hello, On my old computer Thunderbird gave me two horizontal planes - the top one listed messages, the lower on showed the selected message text. On my new computer, the full screen shows just the list of messages but does not have thew lower pane to display the selected message. How do I reset this please? Grateful for any suggestions. Thanks, Paul

The navigation bar on my Android phone is currently at the bottom. There is no settings option to tap on to change it back to the top when I tap on the three dots menu. How do I get the navigation bar to go back to the top?

Good morning, I has been using Thunderbird for my email account for several years. For the first time I encountered a problem that Thunderbird seems not to see sub folders I have created on the IMAP server. They suddenly disappeared and when I go to synchronization, the program does not open the list to select folders to download. I tried to restart computer, close and open thunderbird, but nothing seems to help. I will appreciate advice or assistance. Kind regards, anna.

Well looks like they did it to us again. My tabs are back on top again and need to put them below where I am a lot of other users like our tabs!

Update: Codes working fine now for 133.0

In the previous version of Firefox I could install a multiple language keyboard layouts in the upper right row. I had to reset everything with a new HDD and Ubuntu 24, which comes with Firefox for Linux as well. Now I can't find how to install those shortcuts that I had before. I need to use Slovenian, Italian, Spanish, German and US keyboards (UK is standard with UK English as primary choice). Thank you for your help.

Platform is Linux Mint 21.3 Cinnamon Thunderbird 115.16.0esr (64-bit) I must have caused this problem while making a mistake while adding a google gmail takeout file to local folders.

Now account settings shows Local Folders / Local Directory as:

   /home/xyz/Downloads/Google Takeout/Takeout/Mail

In Local Folders the Outbox folder properties location shows:

  mailbox:///home/xyz/Downloads/Google Takeout/Takeout/Mail/Unsent Messages

In another Linux system Thunderbird shows Local Folders / Local Directory as:

  mailbox:///home/xyz/.thunderbird/g44es9f2.default-release/Mail/Local Folders/Unsent Messages

Which tells me basically where it should be pointing.

I tried to change (in account settings) Local Folders / Local Directory using the Browse... button but the Select Local Directory window doesn't give any access to the .thunderbird folder.

How can I change the account settings Local Folders / Local Directory back to what it should be?
