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.

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?

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.

I added the Cardbook extension and I want to import a CSV file with contacts from Outlook. Is there a way to do this? Can you export from Cardbook? Thanks, -- Haig

Suddenly, a few days ago, this add-on quitted working, the box where you can type the string to search for is not functioning. It is visible, but not active. Tried disinstalling and re-installing, but nothing. The add-on seems compatible with the versione of Thunderbird, the 141.0, but in reality doesn't work. Could anyone here give a help?

Thank you in advance

Hi! I have been using Shrunked Image Resizer's module for a long time (reduces the size of attachments before sending). It's no longer compatible with the new version of Thunderbird (140.1.0). I don't find any alternative module to replace it. What's the solution please?

When composing a message I am getting a pop-spell check window that auto-fills the top (somewhat bizarre) suggestion. This is suboptimal for me, though it might be entertaining to compose auto-suggest random word salad messages from time to time. The heretofore behavior was to red-underline unrecognized words and permit a right-click pop-up selection for correction.

I run an ever longer list of plugins to maintain the core functionality I rely on for messaging and I realize this pop-up could be an artifact of an "upgrade" thought useful by a plugin, but before I go through a day of sequential plugin testing, if someone here knows how to revert this behavior, I'd very much appreciate it:

The insanely disruptive new behavior is the popup offering to correct "things" as "Things" [sic capitalized for some random reason, though I'm quite smitten with "Th�ringens" as a "correction" to "things"]

The good (olde fashionede) spellcheck offers to correct the intentionally misspelled "thinglys" to "thingy" and correctly ignores "things".

Thing (ha) is the not-for-me version and the good-by-me version are both 128.13.0esr (64-bit), both have "enable spellcheck as you type" enabled, both are set to English (United States) (though, oddly, the order of the dictionaries is different), and both run roughly the same set of plugins, both are on Linux, bad-for-me on Ubuntu and good-by-me on Mint.

I checked Advanced Preferences for anything that might be inducing this odd popup and couldn't find anything obvious under "spellcheck" or "suggest."

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

A number of times when I'm answering email and need to check back on the list of emails, I don't see a Tab to take me directly to my list of email accounts (I have 8). A couple of times I've had to shut down T-bird and re-launch it to get back to this list/window. I don't understand why such a Tab isn't available everywhere.

So I'm looking for an add-on which would allow me to add a specific Tab on the T-bird pages where it isn't there, specifically, a Tab to get to the window which has the list of my email accounts.

If there is such a customization, I'd appreciate getting a link to get it.

I'm on 141.0 (64-bit). It says I'm on the "Release update channel." Quickfolders isn't working. How do I get to an older version of Thunderbird where Quickfolders will work again?

When I click on the Add-on compatibility check drop down arrow at the top the message box for add-ons is too big on the screen so I can't see the whole list to the bottom of the box and the box isn't resizeable? Anybody know a solution please?

I'm trying to setup tbsync to use with Google Contacts. I'm running 128.12.0 esr. I've installed tbsync and Google-4-tbsync.

I followed the instructions to create Google credentials, but where do I put them? And the account setup for tbsync asks for a "client secret" - what's that?

I recently added the Send Later add-on, but, when I click on the "Send Later" button, a pop-up briefly appears for a fraction of a second and then disappears. Is there any solution to this? Thank you in advance.

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.

Hi there, I'm experiencing an issue with the Microsoft Teams add-on in Thunderbird, specifically when using it with multiple Microsoft Exchange accounts.

Issue Description:

Previously, I was able to select between accounts using the Teams icon in the toolbar without any problems. However, after switching operating systems, the behavior has changed:

• When I hover over the Teams icon in the toolbar, the account selection menu appears as expected.
• As soon as I move the mouse to select an account from the menu, the menu disappears immediately before I can click anything.
• I've made sure that the mouse doesn't leave the icon or jump erratically, but the menu still vanishes every time.

This only started happening after I changed my OS. On my previous setup, the add-on worked fine.

Fixes Attempted:

• Removed and re-added the Exchange Accounts
• Reinstalled the Owl for Exchange add-on
• Fully uninstalled and reinstalled Thunderbird, including manually deleting the profile data folder
• Disabled hardware acceleration

So far, nothing has resolved the issue, and I haven’t found any other reports of this specific behavior online.

The attached image shows the account selection menu when hovering over the teams add-on, but as soon as the mouse moves over to the menu it disappears.

System and Application Details:

• Thunderbird Version: 139.0.1 (64-bit)
• Operating System: Kubuntu 25.04
• Desktop Environment: KDE Plasma 6.3.4
• Display Manager: X11
• Kernel Version: 6.14.0-15-generic (64-bit)

Any suggestions or workarounds would be greatly appreciated.

I see duplicate menu items for addons under Tools menu for some addons like ImportExport Tools NG for example and its developer identify the issue as longstanding Thunderbird bug on Mac.

Any idea about the isse?
