This evening, Thunderbird has updated to the new version (can't see where the version number is held, unfortunately). Whenever I try to download new emails, I now get the message "Error with account [email address]. Sending of username did not succeed. Mail server pop3.iomartcloud.com responded: Mate, the command must be one of CAPA, USER, PASS or QUIT." Mails are still accessible through the mail client on my phone and through webmail, just not through Thunderbird.

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?

The folders and address lists exist in .thunderbird/5sdfwbvt.default /Mail/Local Folders

and in  .thunderbird/5sdfwbvt.default/storage/abook/mab  and abook/sqlite

How can I get thunderbird to access these resources??

I have used Thunderbird for years with automatic update. Got a Big yellow warning - something like: this is a test version, the profile must not work in esr version. I immediately stopped. Downloaded the esr version and started it. Thunderbird could now not read my profile an initiated install procedure. I saved the profile. Can I see in the profile which version of Thunderbird it can be used under ? You aught to give i clear warning in test versions when you change an user profile.

LINUX. see subject, please. i started on this laptop w/ mint. 5 or 6 years ago. then downloaded peppermint 1 and has been working great, but the browser does not update automatically like is said. Then, my Linux guy up and passed away. I know no one in town that uses it. I'M ON LINUX. any help appreciated. have gotten some replies with folk trying to help, but it just wants to download/install whole program. my bank wants me to upgrade to at least 115. can't access accts. Chase are useless. They don't know what Linux is. Perhaps someone here can point me in right direction? Regards. God bless.

I downloaded Thunderbird 120 and installed. All I get is error message saying windows is searching for thunderbird.exe and nothing else. Old version has disappeared and I can not uninstall - get same searching for uninstall.exe. I have tried re-downloading it and re-installing it 4 or 5 times, still nothing. help please.

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.

browser.cache.disk.enable, is re-enabling itself on every Firefox update. WHY?! I disable disk caching and SSL caching because I use a fast NVMe SSD and I don't want to use up all the write cycles to it.. cookies caching is fine with me...

It has been doing this on every update for a while now.. this is annoying and not ok.. please fix.

I'm setting up a new Thunderbird installation and email accounts. The account setup fails because it cannot sign into the server. I believe the issue is between the account ID and the email address. They are different. The server requires an account login in the form of wxyz in order to access email in the form of a@bc.de. The account ID password is the same as the email address password. I've tried using wxyz in the account and get smtp connect failure. If I use a@bc.de in the account I get the same failure. This is a working email account that I've had for 30 years. I've tried imap as well as pop3. Both fail the same way.

Videos won't load in previously enjoyed timeframe or indeed et all sometimes. timeouts when loading pages. speeds are like 15 years ago even in troubleshoot mode and after refresh. when can I expect improvement?

Tried installing v115 latest on Ubuntu. Hangs when I try to set up email acc and it tries to log into the Gmail server. "Danger ahead" displayed on page with no option to force it to proceed.

Thus please dispense with any solutions for this and just inform how I can install v91.1.2 using apt-get

I see you list the versions but I see no where on how to specify which version to install.

I am running Thunderbird Flatpak from Flathub on Linux Fedora.

I just checked for updates in Software app. I noticed a few, plus system updates so ran them. I remember seeing Thunderbird reported something weird like ‘v128 [arrowright] v115’. I am making that up but I remember two numbers and the left hand one was a higher number than right hand one.

I thought it was odd but carried on, assuming Software updates never go backwards so it must be some weird anomaly. After rebooting, after updates done, I now get an error/warning when I open Thunderbird…

I’m now confused and worried I screwed up my Thunderbird, in which is 20 years of email. Hoping someone can allay my fears and perhaps advise what I should do? thanks

I've setup Thunderbird as my new email client but I'm getting the following error message on both mailboxes. Went through manual confi and it said all was good. Can't figure out what I'm doing wrong. Any help greatly appreciated tks - patrick replies to: prpa1440@gmail.com

Installation aborted because the add-on appears to be corrupt. OmegaSwitch

Hello, I encountered an error when trying to install the extension. I've never encountered anything like this before

After updating with Mozilla 129.02 yesterday my platform freezes completely after about 30 secs. I cannot even get the Task manager to work. I have to switch it off at the mains and hope the switch back on is not too harmful. ( 'Update' is fast becoming one of the most scariest words in the English language)

I can't get firefox to play amazon music web page or netflix because it claims to be installing an app which it never completes. I've tried to purge cache for the site in question, to no avail. What is the solution?

I have about a dozen accounts set up on my laptop. I want to have the same accounts on this desktop system. I am loathe to do so by using the standard Tools > Account Setup process because every time I have done so in the past several months, I've had validation problems with the email servers at the ISPs. I've had to change every password to create baseline values before TB could add them even though I had valid passwords copied from a password vault program.

Is there a way to just copy or transfer the data from the laptop to this desktop? I have a couple of the accounts set up here but would like to bring the others over without having to go through the setup steps.

Firefox was once the most popular browser in the world, but then Mozilla started releasing updates every week and became disgusting. Now Mozilla has a tiny piece of the market, they have essentially lost almost everything, but they continue to shit with updates like diarrhea, which most users do not need and it's impossible to refuse the annoying, ugly constant reminder about updates. I'm not even talking about the fact that after a refusal to update to a new version, there is a forced update to a new version without permission. So, why doesn't this company learn from its mistakes and become at least a little smarter?

I recently bought a new computer and transferred all the data from my old computer to this new one. My old computer was running ESR, which was transferred to my new computer.

Without downloading a fresh install of Firefox and having to lose everything, is there a way to simply move over to the release channel of firefox? I tried syncing it up with my account but I still lost my history. Fortunately, I still have the ESR version of Firefox on my computer.

I tried to import but Firefox ESR wasn't an option.
