The 'Sent' file in my 'Mail' folder exceeds 3 GB (3,224,360,399 bytes) and is not being read in the TB Mail window. How can I reduce the size of this file AND save messages???

'Sent' message folder IS searchable!!!

For some reason, I am getting message that the Certificate for server is not valid (etc.). I can not get or send my emails as of this morning. Is there something I can do to resolve this issue?

Thunderbird, quite suddenly, stopped getting my email; Both on my account and my wife's account at the same ISP. I spent more than two hours on the phone with the ISPs help line trying to resolve this issue. They also use Thunderbird at their help desk, and the agent I talked to was familiar with your program. She (the agent) was not able to replicate the issue on their system. We then tried to set up a NEW email account. I carefully entered all the info needed for a new account, following instructions from the agent, then hit the 'Test' button. I got the following message onscreen: "THUNDERBIRD FAILED TO FIND SETTINGS FOR YOUR EMAIL ACCOUNT" The answer to the original issue suddenly became very clear - Thunderbird cannot, or refuses to, connect with the email server, therefore NO EMAIL. We tried everything in her toolkit to resolve the problem to no avail. We finally tried UNINSTALLING Thunderbird (and the Maintaince program). Once Uninstalled, I used the Registry Tool on CCleaner to remove any entries in the registry referring to Thunderbird (there were several), then restarted my computer. I then downloaded and installed a totally NEW Thunderbird program. When I ran the Thunderbird again, I found all my account(s) info was still present, and Thunderbird was still unable to find the server. I'm at my wits end trying to resolve this issue, and REALLY HATE to go back to Microsoft OUTLOOK to get my email. Anybody got any ideas??? Any help would be greatly appreciated. (Signed) Proteus

I want to sync my Thunderbird calendar on my win11 laptop with my new Samsung Z Flip 6 phone. I have a Google calendar on the phone, and I've ticked "Lightning" on it, but I'm not getting my entries transferred from my laptop.

Can anyone help, please?

Over the past couple weeks of updates, the about:processes page is now missing several elements, such as the memory usage, CPU usage, and the close (X) button for each process/tab. See attached screenshot. Normally each row would show the memory, cpu, and if it's a closeable tab, the X button would be on the far right upon hover.

Let me know what other info you need to squash this bug. Thank you!

Thunderbird started crashing randomly about 2 days ago, however, after restart, it would remain running if I switched to troubleshooting mode. I removed an add-on from Bitdefender in troubleshooting mode.

Today I can't even open Thunderbird-- it crashes on launch. It won't launch even if I hit the Shift key or if I turn off antivirus.

Here is the most recent submitted crash report:

Crash ID: ⁨bp-b52cd345-636f-445a-ab4c-764ca0250114⁩

Can someone please give me guidance on what is going on and how to fix it?

Thank you.

Hi all,

I’ve been using Firefox for a while now, but coming from Chrome, I’m finding some aspects of Firefox’s cache management and tab behavior a bit inconvenient, and I wanted to share my thoughts.

The issue:

When I restart Firefox (version 133.0.3-1), it loads webpages from the disk cache, which is fine because I’ve set browser.cache.disk.enable to true and browser.cache.check_doc_frequency to 2, it will always make a request to the server on restarting Firefox with the default value of 3. However, the problem arises when I open new tabs — they also load from the disk cache instead of requesting fresh content from the server.

What I’m looking for:

   A way to have Firefox:

Load webpages from the disk cache when restarting the browser (which I want, and I have set browser.cache.disk.enable to true for this). But always make fresh requests from the server when opening new tabs, no matter what the cache settings are.

In Chrome, this behavior is more intuitive — it loads from the cache after restart but always fetches from the server for new tabs, which I find to be much more reasonable.

I understand that about:config provides settings like browser.sessionstore.restore_on_demand, but adjusting this option makes Firefox fetch content from the server for all tabs, including those opened after a restart. This doesn’t seem like a perfect solution because it takes away the ability to use the disk cache after restarting the browser.

I would really appreciate it if Firefox could offer more granular control over this behavior, so users could get the benefits of both caching and real-time requests based on the type of tab (restart vs. new tab).

Thanks for your attention, and I hope to see some improvements in future updates!

I'm running Sequoia 15.1.1 on an M1 Mac Mini. Never had problems before. TB 128.6 0 esr.

As soon as it opens it crashes.

I have a lot of unopened files in a pop mailbox, going to try and remove them.

It seems to still work on my iPhone. Any ideas?

I M get this working. I'm in a panic. Please help.

Can a long standing issue — previously closed as "RESOLVED INCOMPLETE" — be recalled as a New Issue?

Ich kann leider kein Englisch. Mein Problem: Ich möchte meine Gmail-E-Mail-Adresse in Thunderbird aufnehmen, bekomme aber immer eine Fehlermeldung (siehe Bild). Ich verstehe das nicht. Ich habe alles probiert; Google aktualisiert, Zugriff zulassen etc. Nichts hat geholfen.

Since 21/12 on my win 10 pc Thunderbird wont send or receive emails . My accounts are all gmail accounts and have been working fine for several years. I get message box as in attached screen shot. I have current Norton 360 subscription and run free Malwarebytes showing no malware etc. Have I been hacked, do I need to delete accounts and reenter them? Help please

I recently (A few hours or so ago at the time of posting this) realized that whenever I right clicked on anything, no matter if it was a link, text, image, or nothing at all, the menu that popped up showed basically every single possible option.

I do not know if anything would actually happen if i tried some of the options on the wrong file types and such, but I have noticed that trying to use some of the options that would appear and work normally before (like copying a link from a redirecting image), no longer do anything. Copying images seems to work, as well as cutting, selecting, searching terms on google, etc.

I do not think I did anything to cause it. I was using my computer normally for a bit before noticing and I think I would've noticed sooner if it was messed up from the start. I also don't remember if my firefox was updated recently, but there were no updates queued when I checked (Currently at Version 134.0).

The image attached is what shows up when I do nothing but click on the background image of the default home page.

I am using Thunderbird to migrate mailfolders from an old email account to my new Gmail accout.

I connected both email accounts to Thunderbird by IMAP. That was a piece of cake. All the folders from my old account synced rapidly with Thunderbird.

Then I started copying (in Thunderbird) email folders from my old account to my Gmail account. But that turned out to be a major problem. In the activity window I can see that the copy speed is in the order of more than 1 second per (simple) email.

What can be the problem?

When my mouse hovers over a link or changes to a new page, the URL displays in the bottom right. This is a feature i like in theory, but the way it is executed, where it displays overlaid on top of the web page, makes reading the web page and interacting with buttons down there frustrating and damn near impossible. this is especially disruptive when using applications in the browser like excel.

where is the setting to make this not an overlay, but part of a separate, bottom bar what is NOT covering the web page?
