HI just updated to 140.5.0esr (64-bit) Now all I can see is my inbox and deleted. No Sent or any of the other many folders I could see 5 mins ago ☹️. The server has them all though Some help welcomed!

My C: drive is almost out of available memory and the following profile, jrqu4wd0.default-release, is the culprit. If I delete it what affect will it have on Thunderbird.

Hello,

I'm writing because I’ve encountered an issue with the tab groups feature in Firefox.

Some time ago, after a browser update, I noticed a new feature that allowed me to group tabs thematically — I could name each group (e.g., "Study", "Work"), choose a color for it, and save and close groups to reopen them later. I found it very useful and used it a lot.

Last night, I decided to declutter my browser and closed several tab groups using the built-in menu. A bit later, I shut down my computer, but perhaps too quickly. This morning, when I turned my computer back on, Firefox was very slow to start. After a restart, everything seemed to work fine again, and the open tabs were restored.

However, all my previously saved (but temporarily closed) tab groups disappeared. In the tab group menu, I can now only see the ones currently open. I’ve searched through all the settings and history but cannot find any way to restore the missing groups.

Is there any way to recover the tab groups that I had previously saved and closed?

Thank you very much in advance!

Systemordner Thunderbird umbenannt und neues Profil erstellt, alle E-Mail Konten neu integriert, Teste i.O.,

Aus alten Thunderbird Ordner war plötzlich keine Profilordner mehr vorhanden? Wieso plötzlich das? Sicherungen hatten leider auch keinen Profilordner von Thunderbird gesichert. Warum werden diese nicht gesichert?

I opened a profile that I had just used recently to a blank tab bar. I closed it and the sessionstore-backup folder did not have a recent backup, The most recent about a week old.

Just for testing, I tried to restore with one of the upgrade.jsonlz4 file, about 2 weeks old, but it also had no session. I then restored one that was 2 months old. That one had a session

Now, Firefox no longer generates the upgrade.jsonlz4 files

Sometime ago I must have made a typo when entering my email address into a pop-up window in Firefox. Firefox continues to find and use this wrong address in pre-fills but I can't find anyway to correct it. I've worked through Settings/Privacy & Security with no luck. Can someone help please? (Windows 10 Firefox 145.02)

Hello,

This is the second email I am sending to get help.

I selected my composing font type and color in setting. When I start to compose an email, the font type and text color are shown as I selected. However, as soon as I start typing the text, the color goes to default (black).

Please advise,

Surendra

Just recently I am no longer able to login to the discover.com site in private mode. It still works in regular mode. I'm using this on a desktop, not the discover app. I spoke to their tech support and tried to do a login while on the phone. They told me nothing was coming through on their end. So, what changed and how can I fix it please?

Dzień dobry Mam otworzone strony Facebook i Mesengera.com w przeglądarce i nie mogę wykonać połączenia wideo i dzwonić do osób prywatnych, na grupach to działa. Natomiast do osób prywatnych nie podświetlają się ikony telefonu i kamery i tym samym nie mogę się połączyć, jak to naprawić? W Chrome działa. Dzięki za pomoc.

Hello,

I am requesting immediate assistance with a critical and persistent problem in Thunderbird.

For my Google Workspace account max@dantanas.com

, Thunderbird refuses to create or recognize a Junk/Spam folder. This is not a cosmetic issue — it directly affects email safety, filtering, and daily usability.

Summary of the Issue

Thunderbird does not automatically create a Junk or Spam folder for this account.

Attempts to manually create a Junk or Spam folder fail or are ignored.

Thunderbird’s junk filtering settings for this account are disabled or inaccessible, making filtering impossible.

Other clients (Gmail web, Outlook, mobile apps) create and use a Spam folder normally, which shows the problem is specific to Thunderbird.

This problem has persisted across restarts, folder repairs, and full account removal/re-addition.

Why This Is Critical

Without a Junk/Spam folder, Thunderbird cannot move suspected spam anywhere, leaving the inbox vulnerable.

The built-in adaptive junk filter becomes unusable.

Thunderbird does not comply with Gmail’s standard IMAP folder structure.

This issue prevents Thunderbird from functioning as a secure, reliable mail client for this account.

Steps Already Attempted

Removed and re-added the account multiple times.

Forced folder synchronization.

Repaired folders.

Reset folder permissions in Gmail.

Verified IMAP settings (X-GM-EXT-1, special-use flags, etc.).

Tested other devices — only Thunderbird fails.

Expected Behavior

Thunderbird should automatically recognize Gmail’s [Gmail]/Spam folder as the Junk folder OR allow me to assign one manually.

Instead, Thunderbird behaves as if the account is not permitted to have a Junk folder at all, which is incorrect and breaks essential functionality.

Request

I need help determining:

Why Thunderbird is refusing to create or map a Junk/Spam folder for my Google Workspace domain.

Whether there is a known bug with Gmail Workspace integration that causes Junk folder support to fail.

How to force Thunderbird to recognize or create a valid Junk folder.

Whether this issue requires special IMAP flags, folder mapping changes, or intervention from Thunderbird developers.

This is not a minor inconvenience — it prevents Thunderbird from acting as a secure or usable email client for this account. I would appreciate prompt assistance or escalation.

Thank you, Max Makowski max@dantanas.com

I used to be able to see a running account of the number of messages left to move or to delete.

If this is still available, how do I turn it on?

Thanks.
