Hi! Since a few months, I face the problem that Thunderbird stalls and is inaccessible for several seconds (>20) when a screen refresh happes or sometimes when for example a windows message pops up. I disabled/ininstalled all add-ons and also have reset all setings to their defaults. Has someone the same problem or has a hint for me? Thank you!

I am trying to link RSS news feeds to my Thunderbird home page, but no websites contain the RSS icon I'm supposed to click according to the instructions. Its not on Axios, its not on Semafor, and when I type in the URL it tells me that its not valid. What am I missing? Please help !

Hi: I've just recently installed 135.0.1 Mozilla Browser and have found that the file SAVING-function in the 'Application Menu' does NOT PROPERLY WORK: it records my message-title but NOT the contents (0-bytes!) -I never had such a basic issue in many years of very satisfactory Browser-use ...am I have a wrong setting somewhere and is there any quick fix please ...? - Email me when someone answers the thread ...MANY THANKS, Tony H.

P.S.: Please send me a link where I'd get a help since I'm NOT GETTING ANY HELP FOR SEVERAL WEEKS ...! Thanks-Tony H.

I'm trying to transfer the Profile folder from my current laptop to my new one. I followed the directions here: https://support.mozilla.org/en-US/kb/moving-thunderbird-data-to-a-new-computer but must've made a mistake because none of my many Local folders have populated Thunderbird in the new laptop. Also, the GB size, number of files and number of folders show to be very different on the new laptop vs. the current one.

I'm inclined to just start over but have a question. Can I simply delete the contents of the "Thunderbird" folder under "Roaming" in my new laptop and try again to paste into it? Or are there some items in that folder that were inserted when I first downloaded TB into my new laptop so that doing a complete deletion would remove those and they wouldn't be replaced when I try pasting again? If so, how do I get around that?

Thanks very much for your help.

Important update! On March 14, 2025, a critical root certificate in Firefox will expire. If you’re still using an older version (before Firefox 128 or ESR 115.13+), it’s crucial to update to Firefox 128 or newer to avoid issues with add-ons, DRM-protected content, and other features.

For full details, check out Update Firefox to prevent add-ons issues from root certificate expiration.

If you have questions about the update or need help with the process, this is the place to ask! Whether you’re just starting or you’ve already updated and want to share your experience, we’d love to hear from you.

I need to import an MBOX file, but every version of ImportExportTools NG says it is incompatible with my version. I checked and it says I am up to date for Thunderbird, version 136.0. What can I do to be able to use ImportExportTools? Or is there another way I can import the files?

I have a Thunderbird email account on a Windows PC & wish to move it to a new Linux PC. On Windows I used the Export facility to save the entire account to a zip file, transferred that file to Linux & used the Thunderbird import facility.

This failed immediately...

• The Thunderbird main desktop window vanished, leaving no progress feedback.
• I gave it quite a long time to complete the process but there was no further feedback.
• I then right-clicked the icon, Quit Thunderbird & re-started it. No desktop window opened.
• The only thing that worked from the right-click pop-up was the Write New Message function which did open a new email message.
• I then uninstalled Thunderbird selecting the full uninstall option to get rid of any account data, & re-installed it.
• Still the same problem: no main desktop window, & only Write New Message works.

Any advice on what may be wrong & how to fix it would be much appreciated.

This has been re-posted. In error my first post said ‘Firefox’ NOT ‘Thunderbird’.

Hi all. I recently had a terminal problem on my Win 10 computer so have bought a new Win 11 machine. I ran Thunderbird mail on the old Win 10, had 5 email accounts, had about 12 local folders and had my Profile stored in a folder on the desktop. The folder was moved there some years ago but don 't remember how I did it. I moved it there because this folder gets backed up every night.

So, I have managed to remove the HDD from my old machine and have located the 'old' profile folder. I now need to re-install Thunderbird on the new machine and match it up to my old profile folder (I think...)

Any advice on how to do that?

I am trying to migrate my old Roadrunner (Spectrum) email account into Thunderbird. The auto create feature will not work with the settings that Thunderbird is finding. I have verified all of my information settings with Spectrum Support, and they tell me that Thunderbird has to supply me with some sort of special settings to make this work. Any help finding this info will be appreciated.

Hello,

Moving from an older Ubuntu 18.04 machine where Thunderbird is limited to version 102 to a newer machine running Mint 22 where the current version is 128.6

According to https://support.mozilla.org/en-US/kb/upgrading-older-version-thunderbird This should work without issue but the latest version mentioned in the article was 115.

Any change since the article was written? Do I need to install older versions to handle the migration to the latest?

Alternately would using the Export / import tools be better for this task than transferring the profiles?

Thank you
