Every now and then a folder flag will change to the drafts flag/icon, it seems to be a random occurrence which can happen to any sub-folder. Up until the most recent Thunderbird upgrade I had a working extension called FolderFlags which allowed me to go into the Folder properties and change it back but that extension no longer works with the latest version of Thunderbird and there is no alternative extension. How do I change the flag back to it showing as an ordinary sub-folder in my Inbox instead of Drafts? As an interim measure I've created a new sub-folder and copied the emails from the old into the new but that's not ideal at all. I hope somebody will create an updated extension but has anyone any other suggestions please?

I have used Thunderbird for decades with no problem. On a new Windows 11 machine, though, I am having a problem. I am running 128.4.2esr (64-bit) and just reinstalled it, but keeping the profile folder.

When I start Thunderbird, it should open to mail, specifically a unified inbox and various other mailboxes below. Instead, usually, it is blank. Other reopened tabs correctly display their title and content. See screenshot.

Thunderbird works correctly if I start it in troubleshooting mode, but at this point my few add-ons are disabled. (Quicktext, Compact Headers, dark theme.) See screenshot, lightly redacted.

With Thunderbird running, in its bad mode, selecting "mail" brings up the same blank page. Also, "calendar" shows a correct list of my calendars but will not display their content. However, "address book" works, showing my address book correctly.

If I am lucky or patient -- waiting for the mail tab to potentially come to life -- Thunderbird occasionally works and, if it does, stays fine for days, as long as I don't close it. What could be going on and what should I try doing?

Thanks for any and all help.

AI "summaries" or "explanations" have been popping up in front of actual useful text that I want to read. How do I disable this AI summarizer or turn it off? If this removes an AI chatbot, even better.

In Outlook it is possible to have the favorites fixed in top of the folder pane column. This is very handy when moving emails from the inbox to often used folders which fall outside the displayed part of the folder pane. (You don't have to scroll back if you want to display the content of the inbox). I cannot find a way how I could do this in Thunderbird. Is there a way to fix favorite folders in top of the folder pane?

This question was asked 10 years ago but I can't find where a fix was ever found for the latest version of TB. I would really like to keep the favorite folders in sight while scrolling down through the other folders I've created.

Is there an add-on for this? I searched without finding one.

All of my addons are disabled and won't re-enable!

They all say "addon name" could not be verified for use in Nightly and has been disabled. See attachment clipboard00.jpg

If I try to install an addon from the recommended extensions settings (for example "return youtube dislike ") I get a message bubble stating "The Addon downloaded from this site could not be installed because it appears to be corrupt. {OK!}" See attachment clipboard01.jpg

The message above about addons appearing to be corrupt happens if I go to any of my current addon pages and try to redownload them.

I keep installing the Add-on to customize the message body toolbar. Unfortunately, the toolbar returns after a while. Now I can't seem to find the Add-on to customize it.

Any ideas? James

I'm trying to get the calendar app working in a new Thunderbird installation. Here are my notes on what I tried: https://addons.thunderbird.net/en-us/thunderbird/addon/lightning-calendar-tabs/versions/ Download lightning_calendar_tabs-3.8-tb.xpi (latest version) to C:\Users\ken\Downloads In Thunderbird: Tools --> Add-ons --> Gear icon --> Install add-on from file --> C:\Users\ken\Downloads --> lightning_calendar_tabs-3.8-tb.xpi "about:addons Lightning Calendar Tabs could not be installed because it is not compatible with Thunderbird 144.0.1." Any suggestions?

Do add-on settings get backed up when backing up a profile? I always have to manually install my add-ons when reinstalling a profile. I have one add-on that is a pain to set back up (Identity Chooser), and I have assumed the settings for it are lost.

Suddenly messages have disappeared from all folders; all I see is No messages found.

I tried Repair Folder. It appeared to work, it ran for several minutes on my Inbox, but that didn't help.

I discovered that if I run in Troubleshoot mode that all messages appear, but when I close Thunderbird and relaunch, which opens without Troubleshoot mode, that all messages have again disappeared.

I'm running 128.11.0esr with windows 10.

Dear Sir,

Firefox is not working with Rabby Wallet and Metamask extensions.

It does no pop-up the window to see the transaction and sign it. Firefox 134.0.1 (64-bit). Windows 10 Home.

On Metamask at least I can click on the pinned extension and see the window. However it´s not the expected behavior, because it should open the pop-up automatically. With Rabby wallet it is impossible to proceed, even clicking on the extension icon.

Please fix it.

Hi All,

I have a number of computers that I would like to have configured identically, including Firefox's extensions. Is there a mechanism that I could use to automatically install a list of extensions on my (linux, windows) computers?

TIA, Mike.

I PAID for "dark reader" I got the activation key but I cannot activate it because the instructions says go to "MORE" and there is NO "MORE"! I hunted all over the settings & extension & themes, but I cannot find anyplace to activate this extension. Did I just waste my money? I have poor vision, I NEED a dark page with white letters. Thanks to being a touch typist, I don't need to see the keybord or page to type but i can't see what I am typing on a dam w hite page! I now cannot click on "Email me when someone answers the threadil"

Why there is no way for me to review or rate add-ons for the Firefox? Many years I am using Firefox and sometimes I just cant understand what a strange bugs I am facing.

I am finally making the move to ditch Microsoft Outlook for good and use Thunderbird as my daily driver for all my email needs. One of the things I did appreciate about MS Outlook is that it has a setting where if you've opened up an email and either delete it or move it to a sub-folder, you can set it so that the program will open either the next or the previous email in your list automatically so that you don't have to go back to the main view every time.

I've tried searching the support forums to see if such a feature exists in Thunderbird but I have not yet been lucky in finding any recent information. Does such a feature exist or has someone written an extension that can do this?

In /Library/Preferences/org.mozilla.firefox.plist:

``` <plist version="1.0"> <dict> <key>EnterprisePoliciesEnabled</key> <true /> <key>ExtensionSettings</key> <dict> <key>cloudmetering@snowsoftware.com</key> <dict> <key>install_url</key> <string>https://raw.githubusercontent.com/SnowSoftware/agent-firefox-extension/refs/heads/main/cloudmetering-v1.2.3.xpi</string> <key>installation_mode</key> <string>force_installed</string> </dict> </dict> </dict> </plist>```

In about:policies: {"cloudmetering@snowsoftware.com":{"installation_mode":"blocked","install_url":"https://raw.githubusercontent.com/SnowSoftware/agent-firefox-extension/refs/heads/main/cloudmetering-v1.2.3.xpi"}}

The plist file did read "blocked" at one point, but it no longer does. Why isn't firefox picking up the new value from the plist file? Restarting/refresing FF has not helped so far.
