I understand that Postbox, based on Thunderbird, will never be updated to become compatible with Apple silicon chips. Therefore Postbox will cease to work when Rosetta will be deprecated on macs. Consequently my question is where can I find directions to import messages, filters, and preferences from Postbox to Thunderbird?

I am using Thunderbird on Windows 11 and I have foolishly allowed it to update itself to release 128.1.0.esr without checking the bug reports first. Now it turns out that this release removed the possibility to search the calendar for past events, which is absolutely essential for me. There is a Bugzilla entry for this but it is bogged down in discussions about who needs which date ranges to search in and how many instances to show for recurring events, so I don't expect a solution any time soon. How can I revert Thunderbird to the last release which still has that functionality? I have regular backups of my userprofile folder in case it helps.

Does anyone know how do I can get my feeds back? I hope all my saved feeds are still stored somewhere as I use them for research. I just went to look something up and the whole heading is totally gone!

I just installed an update when prompted by Firefox. Now I can't log into Hotmail.

FF 129.0.2 x64. The update restarted FF. Everything else seems to work OK. But when I go to Hotmail.com, at first it displays my Hotmail inbox - which is odd; all other webpages requiring a login were logged out when I installed the update, requiring me to log in again - but then it switches to an error:

Something went wrong and we can't sign you in right now. Please try again later.

The Microsoft account login server has detected too many repeated authentication attempts. Please wait a moment and try again.

The same Hotmail account is still logged in and functioning on Chrome. This is why I think it's a FF-specific problem.

Thunderbird did an auto update this morning and failed to restart. I get a message that says this version is incompatible with the last. I pay over 20 bills from folders I created in it the applications inbox, house billing info and passes and links to the pages and responses, etc. This is a MUST for me that this thing works and works well. Until this morning it was flawless in that capacity. My only fix after extensive research has been to download the newest version from the website, install it and it starts fine...until I close it, then it fails to restart with the same identifier. Each of the two times I have closed it I go through the same thing upon an opening attempt.

I'm now looking at different mail options as I'm on SSI and have one shot at paying bills a month and can't afford to be any later than SSI already makes me, though my creditors have been thus far understanding. I now have to keep my computer on and the app open until I'm paid on the 9th so I can be sure to be able to pay my bills. I don't know what you folks are shooting for by tinkering with an already flawless system but you missed this time I'm afraid. Leave it alone or let us keep our working system while you offer "new and improved" to those who like to play with new toys. Give me back my old working system before I'm forced to look elsewhere for a way to do my monthly duty to my creditors. Sincerely, Arthur Kelly

When i do update my configuration settings changing by itself. Example, "browser.cache.disk.enable" is "false" but after every updates its always changing to "true". This happens only after updates.

Hello,

After upgrading the Thunderbird to the latest version (128.0.1esr (32-bit)), and trying to switch View->Layout->Classic View to Vertical View, and back to the Classic View, messages from last almost 15 months are not visible. Messages prior to 15 months ago are visible, and from that point, just couple of them showing totally unrelated content than nothing; looks like something is corrupted.

After the latest Thunderbird upgrade, one new message arrived and everything looks OK.

Any hint please?

Thanks. Branko

I just updated my iMac from Mojave to Catalina 10.15.7. I thought Firefox would provide an update to convert the esr version to the standard Firefox browser since I am no longer using Mojave, but the next update is 115.15.0esr. Is that correct? My understanding is that the esr updates are just for computers using older operating systems through Mojave. I did not update to 115.15.0esr since I am not sure if that is the right version for Catalina. Any information and assistance you can provide me is greatly appreciated. Thank you.

Hello everyone,

support for Windows 7, 8 and 8.1 will end in September with the end of the ESR 115 branch. Corresponding support article

Is this still the current status or are there any plans to support the old Windows versions for a little longer?

Thanks and regards, Martin

Hallo, ich habe einen neuen PC mit neu Win 11. Da habe ich Thunderbird neu installiert. Alle meine Mails sind bei Web.de gespeichert. Durch die neue Installation sind alle persönlich angelegten Ordner unter dem Ordner: "Lokale Ordner" verschwunden. Wo kann ich diese wiederfinden? Liebe Grüße Hans

I've noticed that after a few months Firefox ESR will go from being one specific version to two different version tracks. Eventually the older track is removed and the newer one is continued until it then splits. Can someone tell me why this happens and is there an easy way to swap over to the current track? I've included an attachment of what i'm talking about.

For a few days now whenever a new tab opens, either by clicking a link in search results or by clicking a link in an email, the cursor jumps to the bottom of the page and I have to scroll to the top of the page. I'm just getting started with Windows 11 on a new computer. What happened to cause this?

Hi On my Computer I have some locale folders with a lot of mails. Have installed Thunderbird on my Android Mobile and want to see all these locale folders. How and where do I place these locale folders to be able to see them on my Mobile ??? Have attached part of my Mail window to show locale folders. Regards John Gyrud

After a crash I had to reinstall ubuntu and switched to 24.4 where Thunderbird is installed via snap.

I have my old home directory with my old .firefox installation and want to copy my data from the old installation to the newe tb. How can I do this ? brds

I have only my profile file (eg 1b3ylg2i-default) from backup. I copied it into the Thunderbird\profiles folder on the new computer. I have tried changing the information in the parent higher up files (installs.ini and profiles.ini) to match, but no luck. Thunderbird complains that it cant find my profile. The source computer is dead, I have only this file as backup.

Is there a way?
