I forwarded an email from a different email client to my Thunderbird email client and when I opened that email the left margin was gone. I tried selecting the text and clicking on the right index and nothing happened.

This type thing has happened before when I forward something that comes to my TB account, but usually highlighting the text I add, and clicking on the right index, will move it over a bit.

I would like to know why this is happening, and if I can prevent it or solve it when it does. It looks so unprofessional and sloppy when there is no left margin.

Thanks, NM

I am using Thunderbird 140.8.0esr (64-bit) on Kubuntu 25.10 multi-monitor configuration. New install, very little customization.

Thunderbird will not retain the window size or position for the main window or messages. I have have tried deleting both the xulstore.json and session.json files (one at a time and both). When I delete the xulstore.json file and restart Thurderbird, it starts maximized. When I set the position manually e.g. to use about 90% of the screen for the main window and about half the width and about 90% of height for a message window and then close Thurderbird I can see the new window size vales written into xulstore.json e.g 2493 x 1362 and 1501 x 1317 "messengerWindow":{"sizemode":"normal","screenX":"0","screenY":"0","width":"2493","height":"1362"} "messengerWindow":{"sizemode":"normal","screenX":"0","screenY":"0","width":"1501","height":"1317"}

When I close and restart thunderbird it reverts to opening in the center of the primary monitor at a smaller size than when I closed it. The values in xulstore.json have changed to 960 x 540 "messengerWindow":{"sizemode":"normal","screenX":"0","screenY":"0","width":"960","height":"540"} "messengerWindow":{"sizemode":"normal","screenX":"0","screenY":"0","width":"960","height":"540"}

I found a similar recent question if this helps with a possible solution: https://support.mozilla.org/en-US/questions/1527783 but I cannot locate the referenced userChrome.css file to see if there might be something similar to try.

I am also using a multi-monitor setup. If I move the Thunderbird window to the second screen and close it, it always re-opens on the primary display at the 940x540 size. Thanks!

Very little to do with accounts, but none of the selectable topics cover 'user Interface'.

Used to be able to open different accounts in different windows. Can't remember how, but it was obvious. Once new window is created, each time Thunderbird is started it re-creates them. I accidentally closed one and can find no way to re-open it. I use three email accounts each needing a different mindset, so keeping them in different windows helps. Also one has a screendepth full of folders and so is easier to handle in its own window. (The others are still there but only take up one line each when collapsed.

140.7.1esr (64-bit) Mozilla Thunderbird Snap for Ubuntu ubuntu-snap-build - 1.0

Why does the spellchecker have to check the original message, as well as the reply? The original message always shows errors, if only because the sender's email address isn't in the dictionary or the sender didn't bother with capitals, showing his name as "jeff", instead of "Jeff". I end up clicking Send Anway every single time.

Hello, For 2 unsuccessful hours of trials, Mistral didn't help me, nor the configuration editor (but there are so many parameters...). On Windows 10, with Thunderbird 140.7.2esr : when clicking on http/https links in messages, I would like to make thunderbird opening my web browser but in private mode, while this mode is not the default one. I know the flag to use to run the browser in private mode from a command line, and it works. But i do not know how to declare it for/in Thunderbird. Mistral answered me that there is a network.protocol-handler.http param to set, but i have not found it or somewhat similar in the config editor. Any help would be welcome. Even better would be to be able to choose through a contextual menu how to open the link, as it is possible in the web browser. Thank for any hint.

When I edit a Sent Email as "Edit As New Message", I usually change the subject line. I do this with the hope tthat his new message I am sending becomes a new thread. Unfortunately, it shows up as a thread under the original email, which I edited

How can this be fixed?

Links to websites included in emails received to not work. When I click the link I get a pop up message that says:

"Windows cannot access the specified device, path, or file. You may not have the appropriate permissions to access the item."

It aIso appears when clicking the "Get Help" button in the Help drop down menu.

I'm about to travel for over three weeks, and I'll be paying for internet usage by the MB most of the time. When I check messages in Thunderbird, I'd like to prevent remote content from loading - I don't need to see all those images and such during that period. The global "Allow remote content in messages" setting is already off, but I have many "exceptions", and I don't want to just delete all the exceptions and start over allowing them one by one after I get home. Ideas?
