Dear community,

As I use a few self-made unsigned add-ons, for several years now I have been using the Firefox unbranded builds on Linux with great joy. In the past these became available for download shortly after a regular Firefox was released. Lately though things have changed. The current latest release for unbranded is stalling at version 107. So it's getting further and further away from the official Firefox, which is at 109 at the time of writing.

Obviously I'm concerned my unbranded Firefox is not getting the same security updates any longer. I do realize there's alternatives for supporting unsigned add-ons. Running a Firefox nightly or developer-edition is something I'd want to avoid, so for me these aren't real alternatives. I've also tried tracking unbranded info on bugzilla.mozilla.org, but couldn't find anything relating to this 'lag'.

Where can I find more info on this topic? Are these unbranded builds being discontinuated?

Thanks for reading, keep well!

I just completed changing the storage location for Thunderbird email messages, from AppData/Roaming to a new Thunderbird folder under Documents. This was to ensure that my computer quick-backup utility would save emails. I followed Mozilla instructions and all went well, everything seems still to work just fine, except that one POP email account shows nothing in the appropriate Thunderbird Inbox now. Sent messages show up, and new incoming messages to that account go into the Inbox and show, but all the old ones from before the location change just don't populate the Inbox listing area. The Inbox file at the new location has messages in it, I can see and read them with Notepad, but there's no corresponding Inbox message list for that one account. What could have gone wrong, and is it possible to somehow 'activate' the old messages so they show, or move them again from the original AppData/Roaming location to the new one? Thanks!

52.9.0esr is claimed to be the last version for XP. Unfortunately it is not quite true. It is for XP SP2 ONLY. Trying to install on SP3 ends with the message that SP2 is required. IMO the installer is simply too strict on demanding exact version of SP ! https://www.mozilla.org/en-US/firefox/52.9.0/system-requirements/

I went through the list of versions (thanks Mozilla that they all are still available!) and found that the last version I can install is... version... 12.0b6. https://www.mozilla.org/en-US/firefox/12.0/system-requirements/

And indeed I installed 12.0b6 successfully but I would like to install 52.9.

Hi. I downloaded the latest issue of Firefox (104.0.1) to my mobile phone and since then I have been unable to connect to the internet via 4/5G - but it is OK using wifi. This is highly annoying when I need to connect whilst out and about. Weirdly, the calculator on the phone and Samsung Notes have also disappeared and I am unable to download from the Play Store! All the usual things like rebooting, cleaning caches etc do not work. Is it possible to roll back to an earlier version? Any ideas would be useful, given the lack of phone contact available, thanks

Hi folks!

I had to configure a new email which I run from the Thunderbird platform. I backed up a year's worth of emails in a ZIP file before deleting the old email (apparently I had to) and I have followed the instructions to import the old emails. The imported file appears in my 'local folders' section in Thunderbird but these files appear to be empty. I cannot find information or previous questions addressing this issue so I would appreciate any suggestions. The ZIP folder is smaller than 2GB.

Many thanks in advance!

I've always used the "Always ask you where to save files" option when downloading. Recently (beginning of April 2022), files go directly to the Downloads folder. The "Always ask" option is still selected in Settings.

I've tried un-selecting and re-selecting, restarting Firefox, restarting my computer - basically every iteration of 'turn it off and on again' that I can think of.

Hi.

I've recently set up a new computer. I'm a Thunderbird user.

My old computer is running Windows 10. My new one runs Windows 11. I'm running the same (current) version of TB on both computers.

I can't get my emails to move from one computer to another. I know, this sounds dumb, but it isn't; my email provider uses a weird hybrid of POP3 and IMAP, and just "connecting" didn't do the trick; in fact, adding my account to TB under 11 ate most of my emails on the server because the default TB/POP3 setting kills all old emails after 14 days.

Fortunately, my old emails still live on the Windows 10 computer because it DOESN'T do that.

I have tried export/import, but that doesn't work because my account is very old, very large, and creates a 5GB file. I've tried just MOVING it, but TB isn't picking up the old stuff correctly.

I'm pretty sure this is a TB 10/11 incompatibility for one simple reason: when I export just my address book from the 10 installation the import fails on the new (11) machine, BUT when I export it from another machine that's already running 11 I can import it on the new machine.

How do I export mail from TB on 10 and import on 11 ?

Thanks!

My wife has been using Cox Webmail for years and has about 30 subfolders with stuff she needs to keep. We are finally pulling the plug with cox and so that email will be terminated with them.

My question - If I setup Thunderbird as IMAP does it just point to those emails and folders on the Cox servers, or does Thunderbird actually keep those emails within itself locally? My fear is that I set the Cox account up in Thunderbird and all appears well, I then close the Cox account and then Thunderbird is empty.

I've got forwarding turned on in the Cox account and that works fine, but I see no option within Cox to export all the subfolders.

Appreciate any help!

Thanks,

David

Hi, I desperately need help please regarding Thunderbird Email. I factory reset my computer to get rid of a variety of bugs/slowness etc. I downloaded/printed the support info regarding profiles off the mozilla support site. i followed the instructions and saved my profile. there looked to be two profile file folders. i save them on an external drive. Reset my computer. put thunderbird back on, however the new version of Thunderbird doesnt seem to want to migrate my files back. Im really worried that Ive lost my whole history of emails. I have been with Thunderbird for more than 10 years and saved hundreds of emails in various email folders. Ive tried loading one profile folder, the other, then both and all other variations. ive made new profiles and tried to upload my old profiles and nothing works. I did manage to get a couple of my historical email folders to appear, and some sent items from years ago. But 95% of the stuff i still cant upload. Im not very IT savvy, but i believe ive followed the instructions properly. Is there anything else I can try. are my folders saved in the "server" somewhere that i can access? should i try an use an old version of thunderbird? any advice (in laymans terms) would be appreciated very much :) thanks jackie

I've just got a new Win 11 PC and have followed the method to transfer all the emails in my Local folders to the new PC. TBH I've tried many of the methods without success.

I've copied the folders from the relevant directory on the old Win 10 PC onto a USB. With TB closed on the new PC I've copied the folders from the USB to a new Folder in Local Folders directory.

When I open TB, of the ~7,500 emails I copy, only 282 appear

I've tried this many times now with no luck What am I doing wrong please?

Hi there.

This is my first post so bare with me.  :-)

We are deploying the 32-bit version of the Firefox Browser to 4 700 clients and the 64-bit version to only 8 clients; all clients on a 64-bit Windows 10 environment. We will migrate to Windows 11 22H2 this year. The manager for the 8 clients says he wants the 64-bits version just because it's...64-bits. No other reason.

I've read that the 64-bit version can not handle Java, Media Players like VLC and mayby some other plugins. Is that still so?

What is the main reason TODAY for using 64-bit Firefox Browser instead of 32-bit, except for the use of 4 GB+ RAM?

Hello,

I am working to convert my Org to Firefox ESR, but in order to this I need to uninstall the per user install of Firefox. We have many users that have the Firefox.exe located in their Local Appdata folder. So I need to test the uninstall of the Appdata install and then the install of ESR. But the problem is I haven't been able to get Firefox to automatically install into the appdata folder. How am I able to do this? The users who have it installed in the appdata folder are not admins on their computers. When I'm testing I've also been using a normal user account. Please let me know how I can install the exe into the appdata folder automatically without me specifically placing it there or which exe version I need to do this.

Thanks!

I had several address books with selected contacts under my Personal Address Book so that I was able to select them for sending emails to selective groups. Unfortunately my system crashed and I had to reinstall my OP system including Thunderbird. When I upgraded to a new version of Thunderbird I was unable to migrate the contacts within those list to the new address books, unfortunately I don't remember which version caused the change except it was when they moved the address book icon to the left side of the screen. I had copied the respective sub address books to .csv files. How can I import the selected .csv files to a sub folder under my Personal Address Book? Also, how do I copy/paste individual or groups of contacts from one file to another?

Migrated to a new laptop. Fedora 37 Thunderbird 102.8.0 (via Flatpak)

Was able to migrate Thunderbird profile without issue. However, I can not see any of my email folders or the contents of my inbox (All Folders). Under Account Settings/Server Settings/Message Storage/Local Directory is a path to my email folders. Thunderbird see this, but ignores the contents. Instead it created a new inbox, INBOX-1.msf And then every time it starts it creates a new iteration, INBOX-2.msf, etc.

Removing all *.msf files did not change a thing. Still an empty inbox and no other folders shown. And the iterations of INBOX-N.msf continue.

Any ideas on how to resolve this?

With the release of the new ESR version, version 115.x.x, the install creates a shortcut in the Windows Start Menu called "Firefox Private Browsing". How can the creation of this shortcut be prevented during install?

After install, I cannot receive/sync my messages from yahoo, gmail, or other accounts. In trying to troubleshoot, under advanced server settings, I get the error message that the storage local directory is invalid. Your scripts automatically set the directory as /data/home/user/.thunderbird/....however the default directory cannot be edited in the window. When I browse for other directories, your application will not show hidden files, therefore I cannot select the directory which was already installed by thunderbird at /home/user/.thunderbird... This should be reported as a bug as there is no means to select the appropriate directory. It cannot be entered directly in the window and cannot be selected through your browse application. My OS is NomadBSD, on FreeBSD13-RC6.

I have set the synchronization target to be 90 days inside the account settings.

Upon compacting the folders and restarting thunderbird, the messages outside of that range is still in their respective folder.

Is there a way for me to delete the ones out of range, but keep a remote copy on gmail?

I am trying to move Gmail accounts from an old Outlook to Thunderbird due to new OAuth2 rules but can't get the accounts set up in Thunderbird on Windows 10: I installed a fresh copy of 31.8 and Imported emails and address books from Outlook ok. I then installed (upgraded to) 91.10 and tried to set up my existing Gmail account: I type in my gmail username and password and choose POP3 then Done and the Google Credentials window pops up. I enter my email and password and it asks to give Thunderbird access so I choose Allow. The Account Setup screen then says Checking Password and Unable to log in at server. Probably wrong configuration, username or password... If I choose Done it just goes in the same loop. If I Configure Manually I can see all the info and pop/smtp servers are correct and using SSL/TLS and OAuth2 but when I try to Get Messages for the account it just pops up the Google Credentials window and after I put in the username/password again no email is downloaded. There is never anything stored in Saved Passwords either so presumably the OAuth2 token is not being saved? I have tried: Reinstalling Thunderbird (including deleting any leftover Thunderbird folders in Programs and User Data) New profile Ensured Cookies are all allowed Added https://accounts.google.com as specifically Allowed exception In my Google account it says Thunderbird IS allowed access (it adds another allow access entry every time I enter the Credentials) Disabled antivirus (Kaspersky) My Gmail username and password are 100% correct - I can log into webmail using them no problem. I have tried to set up 3 different Gmail accounts and all fail with same errors. Hope you can help as I am completely stuck now, thanks

Moving to a new laptop, running Fedora 36, with Flatpak. Was able to migrate Thunderbird profile without issue. However, I can not see any of my email folders or the contents of my inbox. Under Account Settings/Server Settings/Message Storage/Local Directory is a path to my email folders. While that location is correct, the email folders still do not show for the account. I "Browsed" to them again, and now the Local directory shows /run/flatpak/doc/8cad13c1/mail-remote However, that did not help, as email folders are still not shown. What am I missing here?

Every time I come across a file and click the link to either open or save the file, Firefox just downloads the file -- THEN it asks me if I want to open it or save it..? It's bugged and an obscene security threat if the browser is so easily willing to download files against my intention.

Before I'm asked, I have gone through the settings multiple times to ensure 'Always ask you where to save files' and 'Ask whether to open or save files" are checked. Behavior does not change according to settings.

Example 1. Click link for a PDF with the intention to open, read, and forget 2. Firefox automatically downloads the file to my download folder 3. Firefox prompts me if I want to save the file or open it

If I click 'open', the file stays in the saved location even though I don't want it to exist.
