I posted a question on this forum that I want to delete. I can't find a way to do that. Is there some way to do it? This question isn't really about performance" of T-bird, but about this forum but I was required to make a selection. . . ..

1. Emails won't open to be able to read. They are blank and maybe a few minutes to hours later they will open up and be able to be read. 2. when sending it says couldn't send because timed out then next try it sends but does not show up in the sent file. Also, things do not show up in the delete file. It is very slow to open and log in to whatever the process it goes through as it say "logging in......." This started on Saturday 8/22/26. Please help. I am not a computer geek. I really don't know what is going on. Thank you for your help, Donald

I believe with Update 154,0 my thunderbird has been freezing up. I can't see, to compress files or select some folders. After a few minutes everything freezes up. 21 AUGUST 2026

On my PC - Initial problem was T-bird took forever to load and virtually all new msgs went to TRASH and I had to move to IN-Box. Per help from David - Saved off profile, and reinstalled thunderbird from thunderbird.net. No change. Then UNINSTALLED T-Bird (profile still intact). Now just attempts to open "Looking up imap.comcast.net", but won't open/connect and to close the app I must use WIN Task Master. Can't get to any msgs, etc. Also, in the past when I was able to open, the banner or bar at the top of the page had hundreds of email icons. I sometime have over 1000 emails in my in-box!! I have years worth of emails in folders on T-Bird which I don't want to loose. Help. Thank you. I have a "working" version (with the "trash" and slow loading issue per above) on my laptop, so I can access suggestions on that version of T-Bird. You could also send any suggestions to x@gmail.com

Thunderbird 147.0esr Email arrives. I open it It has the usual 'view this thread' link I click that link waterfox opens all of my home pages.....not the email I have disabled all add ons, in both thunderbird and waterfox....I have changed profile in waterfox & synced with firefox.

The Thunderbird calendar, displayed by the week, Saturday June 27-Friday July 3, 2026 in my computer says today is Monday, Jun 28, whereas it is really Jun 29. Each day in the calendar is off by 1 day. e.g. tomorrow it says Tuesday Jun 29, etc. If I change the view to Multiweek, the dates and days of the week line up as 2 June 29s for Monday and Tuesday!. Wednesday becomes June 30 and Thursday skips July 1 and is July 2! What to do to correct all of these problems? Thanks, [edited email from public]

Hello,

I am experiencing a severe issue with the macOS system print dialog handling in Thunderbird, which started immediately after updating to version 152.

Environment

   * OS: macOS Tahoe 15.5.1 (26.5.1)
   * Hardware: Apple M4 (Silicon)
   * Thunderbird Version: 152 (Issue present) / 151 (Works perfectly)

Description of the problem: When I use the native macOS system print dialog within Thunderbird and select either "Open in Preview", Instead of opening the Preview app Thunderbird bypasses the command and immediately sends the document directly to the default physical printer. The same happens with "Save as PDF", the file-saving dialog is first presented, but after entering the filename the document is also sends to the default physical printer rather than being saved.

Steps to reproduce:

  * Open an email in Thunderbird v152.
  * Select Print...
  * in the Print Dialog window, select "Print using the system dialog" 
  * The system print dialog is opened
  * Click the PDF dropdown and select "Open in Preview" or "Save as PDF".

  Result: The document is instantly printed on the physical printer instead of performing the macOS system action.

Steps taken:

  * Tested with Thunderbird v151: The macOS system print dialog works perfectly as intended.
  * Upgraded to v152: The issue appears immediately and consistently.
  * All other applications (Safari, Chrome, Microsoft products, Apple Mail) work correctly 

This seems to be a serious regression in how Thunderbird v152 handles native macOS print system events and dialog actions on Apple Silicon / macOS Tahoe.

Any help or a fix for this would be greatly appreciated.

Best regards, Michel

Running Win10, all the sudden I'm getting Not Responding messages, failures to connect to server, and slow deleting of emails. I tried everything: uninstalling/reinstalling; running on troubleshooting mode; checking compatibility. Nothing works. Any ideas?

Thank you

This is actually the same in Firefox, and both only since today, working fine before:

Typing Ctrl-C does nothing, Ctrl-X deletes whatever is selected, but it does not end up in the clipboard. In fact, if the clipboard contains something, it will be removed (Win-V still shows it, but it can no longer be pasted). When copying from somewhere else, pasting with Ctrl-V works.

AFAICT, no issues with any other programs.

Latest versions of FF (151.0.2) and Thunderbird (151.0.1), on Windows 10.

What could be wrong?

Thanks, Ralf

MESSAGES IN 'INFOLDER' ARE DELETED AFTER ABOUT 5-7 DAYS, and can't be found I have looked in all settings to try to find the reason, but don't find anything helpful tnx, Al email [edited from public] @ec.rr.com

Ich erhalte die Meldung "Nachrichten konnten nicht in die Mailbox-Datei geschrieben werden. Stellen Sie sicher, dass das Dateisystem Ihnen Schreibrechte einräumt und genügend Speicherplatz zur Verfügung steht, um die Mailbox zu kopieren." Speicherplatz ist genügend vorhanden. Bis jetzt konnte ich meine Emails problemlos abholen. Bin erreichbar über Telefon [edited] oder Handy [edited phone#'s from community support forum]

Previously, when I run a full scan, a box will appear at the bottom of the screen stating that full scan is running and when it's finished, this appears full scan is finished and stayed on until I check Norton. This has not occurred for a long time. How can I fix this? Thank you for your consideration and I look forward to hearing from you.
