We keep track of the latest version of Thunderbird via this link: https://product-details.mozilla.org/1.0/thunderbird_versions.json

Since some time it reports the 131.0 version as the latest stable version. I wonder if this is correct, because the release notes page doesn't mention this version at all.

Response from json: LATEST_THUNDERBIRD_ALPHA_VERSION  : 54.0a2 LATEST_THUNDERBIRD_DEVEL_VERSION  : 132.0b2 LATEST_THUNDERBIRD_NIGHTLY_VERSION : 133.0a1 LATEST_THUNDERBIRD_VERSION  : 131.0 THUNDERBIRD_ESR  : 128.3.0esr THUNDERBIRD_ESR_NEXT  :

https://www.thunderbird.net/en-US/thunderbird/releases/ Doesn't mention the 131 version.

When manually adjusting the version number in another release notes page, it will show the actual release notes. But it mentions that this release is for testing purposes only. https://www.thunderbird.net/en-US/thunderbird/131.0/releasenotes/

Is it possible to change the versions.json to actually show the latest stable version? And perhaps do the same as the firefox_versions.json, to also include the additional ESR channel (esr115).

Thank you in advance

Honestly, i keep trying to support FF but your releases are making me mad. first off my addons are missing after upgrade, they aren't in toolbar or bookmarkbar, they show enabled, but no control exists I use download all images for years, now there is no way to use it .. with the existing version. https://webextension.org/listing/save-images.html i've used this extension literally for years w/o incident.. damn.. this is majorly annoying and disturbs my workflow

why should i have to 'fix' something that was working prior to the upgrade. this is annoying even if some of the browser functionality is improved, your costing me unnecessary work

also why would you located the + new tab control to the left of the 'tabs', you never open a new tab there, always to the far right hand side, the user now has long mouse movements or short-cuts to open, its' broken theUX I've filed a bug on that one.

please you had to know this release had these side effect where are the release notes and the playbook for restoring this add-on functionality.

I installed an automatic Mozilla update and as a result could no longer access my Thunderbird email. I tried reinstalling Thunderbird 128.3 Oesr and placing a saved copy of my Profiles on Dropbox to the Thunderbird folder in AppData and rebooting. I have tried many versions of this but always get a message saying an unexpected occur has occurred. How do I recover my email folders (inbox, outbox, and local) and address book? Together they comprise almost 6 gigs.

Everything always worked great until this upgrade emerged.

Thanks, Bob Gloudemans

Since yesterday I have Thunderbird nebula 128.2.3esr on my Windows 10. But I cannot find my calendar and the new left sidebar isn't available, but only a little button on the left upper corner with seven button without function. I've tried a lot, I cannot find any description about a same failure in the Internet.

Hi really sorry about this I'm new to Firefox & I don't know how to report a possible bug or if this is even a bug but I opened Firefox this morning & my search bar is now at the bottom of my screen even after closing & reopening it

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 keep getting a message on facebook stating my browser(Firefox) is no longer supported even though it is updated to newest version....i have cleared cache and cookies and I still get the same message on facebook. (See attachment screenshot).

Firefox appears as a different application on the Taskbar with some default icon (not the Firefox icon). This happens regardless it is started from the Start Menu or from the pinned Taskbar icon.

This behavior appeared recently, I used Firefox for years on this PC without this issue. I guess it is caused by an update (Windows or Firefox).

OS: Windows 11 Pro 23H2 22631.4169 Firefox: 131.0 (64-bit) Microsoft Store version

When we play any video on YouTube or other video sharing websites, controls in notification panel is not shown, only play pause notification shown. There's no other controls shown forward backward 10s, Next play backward play. Kindly look into this matter and resolve this issue in next update. Notification controls we want in Firefox Android kindly play music on yt music web on Chrome android and see controls on notification panel. You can also see screenshots attached below.

I have been using a usrChrome.css in my profile to create multi-row tabs. (Why cant Mozilla see the need for this with 4K monitors?) The Oct update broke this and I cannot get FF to load the css file that has worked for more than a ywar.

Help please?

I've been on Thunderbird for almost 20 years and a Mozilla fan. Have evolved a fairly elaborate configuration of local (POP) email folders, rules, calendar, and accounts to manage & organize email activity, retention, archiving, etc. I've not had to deal with Profiles in previous upgrades and don't have much experience with it.

The recent Oct 1 push of Firefox & Thunderbird 131.0 releases took me by surprise. I was able to re-implement the previous Firefox profile to recover bookmarks, cookies, passwords, etc. However, when T-Bird warned that 131.0 was Beta & unsupported I took the suggestion to download & install the current supported release: 128.3.0 (I was on 128.2.3). Then hell came.

Once downloaded, installed & launched, Thunderbird 128.3 cautioned the new profile created with T-Bird 131.0 was incompatible with previous versions and that I should create a new one, which I did. Still could not get new T-Bird to recognize previous profile, so I tried uninstalling, downloading & reinstalling 128.3 multiple times, each time prompted to create a new profile before proceeding. I tried to follow the previous profile restoration process detailed on support forums & articles, but none seemed specifically relevant to my situation.

I located my profiles in the appdata roaming profile folder, including what I think are most recent based on size of mail folders. Can't determine whether I had just one or several in use due to the extent of my setup. Could really use some help & advice to: 1) Determine which profile was in most recent use prior to T-Bird upgrade. 2) Whether more than one profile was in use. 3) Re-implement the profile I was using on T-Bird 128.2.3 with my new 128.3.0

Regards & many thanks in advance, John C Houston

PS You'll ask why I would upgrade to 131.0 from 128.2.3. Answer: it was on auto-update and 131.0 is what was pushed. No more auto-updates for this guy!
