... and the only way to restore them is to delete the folderCache.json, session.json, xulstore.json files from my profile directory. But each time I shut down Thunderbird and restart it, the same problem returns and I have to start over.

As this causes Thunderbird to lose all customizations to folder display, column displays, color badges, etc, and requires Thunderbird to download all message headers in my 6 email accounts, it's wasting a ton of my time.

All the accounts are still intact and it even says it's downloading email for each inbox on startup, I just can't see any of it because there's no folders displayed on the left side-bar.

And mind you, this was just a "upgrade"... when I tried to migrate my default profile to another computer (new workstation) it wouldn't load the proper profile without doing the -p flag on the executable and then after, has this same problem where it first displays proper accounts/folders but then on restart loses it all.

Luckily I found another users post online about deleting those internal cache/config files (for a completely unrelated problem with an older version of tbird) or I'd have been completely stuck.

Anyone have any suggestions on migrating BACK to the previous most stable build of pre "Supernova"? This thing isn't fully baked IMO.

And also, is there a better way to submit massive errors like this to the developers?

Thanks...

I just want all of my folders and sub-folders to have the same display columns! With 115, you can change any folder or sub-folder to any column organization you want, but I want them all the same. 115 changed my display columns - why couldn't you leave them alone, Thunderbird??? I can go in and change them back manually, so why were they changed at all??? I don't want to have to change each folder and its child folders individually - I have a few dozen folders, most with dozens of sub-folders. I tried the "Apply columns to ..." and selected Local Folders to change them all - none of them changed! I saw the video from Castellani claiming that TB tried to make sure that upgrading wouldn't take hours to reconfigure back to a usable state, but that's obviously not true if you have more than the one or two folders shown in the video.

Mozilla/Thunderbird -- Is it so hard to leave things as they are and just TELL us there are new features available, if we want them, instead of DESTROYING our well-used setups and forcing us to come here in hopes that someone can save us from hours of tedium just to be productive again?

Thanks to anyone who can save those of us who just want our setups back the way they were!

Store receipts do not print correctly.

How can I attach a receipt to show the difference of "viewing" & "printer preview" & "actual printing" ?

I updated Thunderbird from version 102.14.0 to version 115.1.0 and I have a problem. I don't see any emails, nor folders, nor accounts, nothing. Only on startup do I see the accounts being updated and new mail being downloaded. I can see all the accounts in the account settings. But I can't access the emails. Can you please advise how to solve this problem? Profim can no longer be returned to version 102.14.0. Please help quickly. Well thank you.

Restore previous tabs stopped working after updating to 117.0.1, browser launches the home page instead. Settings unchanged since previous install (see screenshot). OS Win10.

Firefox browser on Android is not opening mail apps when clicking Mailto link. Screen goes blank. No action. Firefox laptop browser works fine, opens mail app when Mailto link is clicked. Picture shows "President" highlighted in orange...this means the link was clicked but the browser didnt execute the send email command, so no mail apps opened. Used Chrome on this link and it opened a window with several mail app options.

Hi, I was trying to set up Thunderbird, but I noticed that the calendar was showing incorrect date+time. I did find a very similar issue very similar issue, but that seems to be because of flatpak (which probably isn't the issue here because I am on MacOS).

Current Time (real, also shown in Mac Menu Bar in screenshot): 03:52 of September 23rd. Time shown by Thunderbird: 22:30 (of the previous day apparently - Sept 22nd).

(Also note how the time shown on the calendar has two days combined. Ideally, 22nd Sept and 23d Sept shouldn't be together in the "Day" view).

Additional note: For fun, I created a new event for 23rd Sept at what seems like 01:30. After creating the event, the time seems to be set to 07:00 (which should be right, assuming that the "Waking Up" event is supposed to be at 09:00). Note that if I open the "Waking Up" event, the time is correctly shown.

ThunderBird Information: 115.2.3 (64-bit)

System Information: MacOS Sonoma - Version 14.0 (23A339)

System Timezone is set to be the same as the one in ThunderBird (Automatic Timezone setting in ThunderBird was even more wrong, by more than a day).

Please forgive me if I missed something too obvious.

Until I updated to Supernova (115.2.2) the CPU usage was low but since the update there is a high usage on a Lenovo Win 10 PC that is up to date.

It seems it is related to the calendar. If the calendar is not brought into focus immediately after starting SuperNova the CPU usage is up around 14%. Once the calendar is brought into focus and I go back to any inbox the CPU usage drops to less than 1%

Just updated to v115.2 and all my messages have disappeared - all folders listed but empty. New emails have downloaded but do not appear in Inbox which is likewise empty. I navigated through Users file to Mail and files seem to be intact. Should I remove update and hope older version will populate the folders? I'm running Windows 10 v22H2 and installed update KB4023057 just prior to v115.2 update.

Hi, I'm trying to play a 360 video I think it uses html5 and webgl. In the desktop version it works perfectly, with the mouse I direct the camera and I have image and sound.

However in the android version I only have sound, the image stays black. I connected the phone with remote debug and this is what I got:

Debug file Mozilla5 Android 13 Mobile rv109 Gecko Firefox114

To play it, I go to the website https://omegaodin.itch.io/00000 I click on "run game" and again on the little play button. Playback starts, there is audio but no picture.

In others mobile browsers as Samsung browser or Chrome, it's working.

I am very novice, but I would like to know the cause and if there is a technical solution that the developer can apply.

Thank you very much for your help.

cannot send email. Can receive email fine. l cannot respond, forward, or send new email. I checked settings, and they seem to be correct. It suddenly started this a few days ago. When sending, icon indicates sending, but get this box:

"Sending of the message failed. An error occurred while sending mail. The mail server responded: <END-OF-MESSAGE>: End-of-data rejected: user smtprelay service AUP suspended. Please check the message and try again."

Now what?

I am using https://infiniteajaxscroll.com on my website https://madway.net . When I scroll down and new set of topics loads, if it contains html5 video it will not load, stay loading. Works fine on Edge browser and Android browser.

Using latest Firefox.

Somehow, Thunderbird updated to a new version. I didn't download or install a new version. I just closed and reopened it and it updated. When I tried to roll back to the new version, I lost all of my emails and addresses! I literally had tons of business emails and contacts and now they are gone. Thunderbird is treating this like a brand new install and I am having to set up all of my accounts all over again! Is there some way to get all of my stuff back? Or has the new install/rollback somehow written over all of my previous data?

Since TB 115, I have issues with the "invite" functionality of Lightning, as follows.

It generates errors as follows:

• "invite" does not work. I can add emails to be invited to an event, but the invite is then not sent at least with the option "notify" + "send individual mail" (other alternatives such as open visible list of destinatories are not feasible due to privacy)

• when opening an "event" from the calendar, it displays in a full-screen format (see screenshot_2) that lists all invited attendees

• The "invite attendees" window works but has a strange pink block on top right (see screenshot_3)

• the page where the format of sending ("notify", "send individual mails") is not accessible any more

Currently the calendar as such works fine. But the "invite" function is critical for the use I am giving as transnational NGO to invite to meetings etc. All worked fine with previous TB versions.

System config: WIN10 prof, all updates installed, fully licensed, AMD Ryzen 9 5900X etc. (mid-end system built in 2022).

Thanks for looking into a solution.

I'm running 115.2.1esr x64 bit on Windows 7 pro. games on Facebook will not load I get 'Your browser does not support graphics API "WebGL2" error'.

In 'about:config' shows GL2 is enabled, yet Facebook games works with Google Chrome and MS Edge browsers, this seems to point to a Firefox issue.

I removed Firefox entirely, cleaning the registry etc, installed the latest version and get the same result.

Can anyone throw light on this? If need be I'll enclose

the troubleshooting info. 

Thanks, Dave
