Hi, After migrating email server, I am having problems synchronizing some IMAP accounts, but Thunderbird is unable to organize the emails and it corrupts the display. In Webmail it is normal and I have no problems accessing it. Coincidence or not, but the emails that are causing this problem are emails that have more than 80Gb. What I did to see if it would improve, was to divide the emails into folders by year, to reduce the size of the email occupancy, but it didn't work. At first, right when I implemented it, they asked to modify this configuration:

Edit → Preferences → Advanced → General → Configuration Editor. Follow the procedure: Locate a key called: mailnews.customDBHeaders Change it to: Received After that restart the application --> Right click on the folder and go to Properties --> Repair Folder

This worked for a few days, but then it started having problems and even repairing the folder, but it didn't help. What they told me was an issue with Thunderbird reading email data on their server, but the problem continued. They kind of "washed" their hands, since it's ok on their server and asked to test it on another email client. Has anyone experienced this problem? Attached is an image of what the email looks like, there are several with the data that I asked to repair, but empty. I've already updated to the latest version of Thunderbird, but it's still like this.

Just Updated to Thunderbird 128.1: Now I Cannot Sort/Move Recipients from TO: to CC: / BCC: and Back on A-Previous Sent (Now New to-be Updated) New Email.... Can I Rollback to Previous 128.0 Version????

Firefox Version 129.0.1 64 bit Windows 11. When I am in a New Tab, and I do a search (Google is my search engine) the results do not display. I type in search words, I hit Enter, and the screen does a very quick blip, and then nothing. This is very frustrating. I have wasted too much time trying to figure it out. It does not do it all the time, but most of the time. This started with the latest Firefox update. Is this a Settings issue?

I would like to connect to Suddenlink.net via Optimum.net. It does show up on Optimum.net account on web page. I have a screen shot of the constant results of my days of efforts. I have two other connections via gmail.com and it works fine. I have people who are still using Suddenlink emails to me and I would like to see them on Thunderbird. Thanks for the fine software and any help with this. //... Joe

The latest rev is VERY slow (several seconds) compared to prior revs to process email changes within INBOX (OPEN, MOVE, DELETE, etc.)

Something new is going on internally to the program while the hour-glass appears for a few seconds more than before (I did not change any settings w/ latest upgrades).

Hallo, ich habe Windows 11 neu installiert, nun habe ich das Problem, das angeblich mein Mail Passwort nicht stimmt. Ich habe schon alles ausprobiert, die korrekten Passwörter von T-Online eingebeben, die Passwörter geändert, nichts hilft. Ich habe auch schon Thunderbird neu installiert, doch alles ohne Erfolg. Könntet ihr mir bitte weiterhelfen, das ich dieses wundervolle Programm wieder nutzen kann?

Hier noch mein System: i7 6700 K, WIN 11 HOME, GTX 970Grafikkarte, 500 GB SSD, 16 GB RAM, 1 TB Harddisk,

Danke im Voraus

this needs to be able to be disabled. I cannot view my reports on medicare.gov due to this security measure. Help and forums are not helpful.... It says just open in a new window, but if you do that, you have to log in and then it is not a new window, and will not open. Now I have to go another browser which irritates me to no end because I have used firefox always. There are many sites that have embedded information and reports that I would like to see, but cannot and they are perfestly SAFE. NOT ok firefox.

Some sites stopped opening, although in other browsers, and through the phone everything opens up. I've tried reinstalling the browser, disabling extensions, resetting DNS. It didn't help. A list of sites I'm having trouble with: https://www.deepl.com/ https://enka.network/ https://7tv.app/ https://hsr.hakush.in/ and some other sites that I can't remember right now. In Chrome he working. Sites like youtube twitch and other poplar working too, idk why firefox have problem, maybe its new update?

After the upgrade to Mac verion 129.0 (64-bit) nothing works anymore. Even turning off the new tracker crap per tab it is not loading a single page correctly even after cleaning the cache. If that does not get fixed ASAP I have been the longest with Firefox, like over 20 years. This new untested tracker stopping just sucks and needs to stop!!!!!!!!

How can I get back to previous version??????

Dear MZLA,

I donated to MZLA, looking forward to an "improved" Thunderbird. I am very frustrated by the result.

Downloaded and started new Thunderbird, and I have several questions:

This is a serious inquiry; I am desperate for information & help.

1. What happened to my address book? How can I get it back? A hundred or more addresses just disappeared.

2. What happened to all of my saved messages? How can I get them back? I used to have a neatly organized file of saved messages. If I was still using Tbird for my business, I would be looking for a lawyer. As it is, I am simply looking for something as useful as the old Tbird.

3. How can I save a message to a specific category or off line file? I used to have several hundred categorized files in my data base for saved messages.

4. Why does my effort to use a help request not respond to my mouse clicks? It seems to always want more donations.

5. Can I go back to the old version? It was easier to use and more straightforward.

6. What am I missing in this "new and improved" version? Is there another email application that would give me the nice features of the old Thunderbird?

7. Can I revert back to the old Tbird and recover the extensive lost addresses and saved messages?

8. If I decide the "new and improved" Tbird will not provide the features the old one did, how can I get a refund of my contribution?

Your early response will be appreciated.

Jon Wilson,

I followed a prompt to compact the data in my Thunderbird email folders. After I did so, I found that the content of all the emails I sent after 4-16-22 was missing. The list of the sent emails was still there but the message box was blank for all those emails. I know who an email was sent to but not what was in the email. This was on my laptop. Surprisingly, these emails did not disappear from Thunderbird on my desktop computer. How can I recapture the sent emails in my laptop?
