I have a profile that causes odd behavior, within the profile, and to the OS.

Regarding the profile itself:

1. I use Multiple Tab Handler, which should allow me to move tabs on the tab bar with the mouse, but it does not (see image of proper behavior)

2. Normally, i can drag this padlock button to the desktop to create a shortcut. but now, it will not move/drag (see image 2)

3. I also have a backup profile from several months ago that has none of the above symptoms. However, If I substitute it's sessionstore.jsonlz4 file with the the one from the problematic profile, all the bad behavior mentioned above re-emerges.

I know this sounds strange, but, I also get external display issues when using the broken profile. These events are random, and manifest themselves differently, so I can't duplicate them. Essentially, these snips are examples of images from the taskbar tabs, or the clock area, suddenly superimposing themselves on the top portions of the taskbar toolbar area.

This is the view of my clock area (see next image 3)

In the following image, imagine that the portion on the left, that opens the start menu, is now hidden under what looks exactly like the clock area on the right, superimposed over it (see next image 4)

Those aberrations are removed by simply moving the mouse cursor over them, but they will continue to occur in any number of variations over any area of that top toolbar.

Is there a Session Manager that will save the session, to be later restored into that previous profile, but not also pass along the corruption?

I am using MacOS 10.13, Thunderbird 115.15.16ESR: my Hotmail worked until 15 May 2025 and then it would not download new emails. Screenshots are available if you want me to post them. I got an error message: "authentication failure while connecting to server outlook.office365.com". I updated Thunderbird to the latest for my OS: 115.18.0ESR. Still no new emails. I deleted my email account on Thunderbird and tried to reinstate it. Now I get an error message when trying to set up the account: "Unable to log in at server. Probably wrong configuration, username or password." I tested my password by logging into my Microsoft account with it on my browser. I can also login to my email using Firefox, but I want my Thunderbird email client to work again.

The configuration I am using is: I use my normal hotmail password in the password field. I also set up a new App Password with Microsoft and tried that without success. With the 115.18 update there is a new field: Your login. I just put my hotmail email address in here. incoming: outlook.office365.com, port 993, SSL/TLS, Oauth2 
outgoing: smtp.office365.com, port 587, STARTTLS, Oauth2 (I have also tried: smtp-mail.outlook.com)

I enabled 2-step authentication with Microsoft in my Microsoft account more than a year ago. Interestingly, I don't get a prompt on my iPhone Microsoft Authentication App when I select Done when trying to set up the hotmail account on Thunderbird.

Please help. I am desperate, and I have wasted a lot of time on this without success. Cheers

I feel like this has been asked a million times, but yet I cant find a current answer that resolves it from all the posts on google. And some are conflicting.

I added my gmail account. Imap. I dont want it downloading and saving thousands of emails. How do I stop that?

Is the only way to do that, by limiting the sync settings to like 7 days? Is this screenshot, the correct area?

I also tried Unsubscribing all the inboxes, Save, close. Then check the Subscribe pop up again, and it just re-checks them all! I cant uncheck them, it just rechecks them.

The recommended methods, changing to this in the registry :

[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Mozilla\Firefox\Certificates] "ImportEnterpriseRoots"=dword:00000000

Reverts back to 00000001

Put this policies.json and did nothing: {

 "policies": {
   "Certificates": {
     "ImportEnterpriseRoots": false
   }
 }

} What am I missing or what's changed?

My specific need at the moment is to add another search engine option in about:preferences#search

Thanks.

This may be more in "settings" than in "search, tag, and share".

Since updating to the 140 series, the URL bar has what appears to be a nonremovable "what kind of search do you want to run?" activated by typing in the URL bar.

Do Not Want. That's the entire purpose of having the separate search bar. For those who only have the URL bar visible, that might make sense, but right in the core Settings I chose to have both the URL bar and the search bar. I do not ever want searches initiated from the URL bar.

Is there a way to remove this unwanted "extra feature"?

And a gentle hint to those doing interface tweaking and redesigns: Those of us who use "separation" features directly supported by the program — that is, not requiring an extension or theme — would really, really appreciate having our choices respected. That the separate search bar is already selected and visible, or having a full menu bar (and not just the hamburger symbol) visible, should be a hint that there just might be functional, safety, security, and/or disability-accommodation considerations behind that user's choice, and you shouldn't override it Just Because.

I was recently asked for my email account password after many years. I have no idea what it is after all this time so I reset my password. I received an email from you accepting the new password. I still cannot login since it will not accept the new password. Who knows what the old one was. I initially tried to recover the old one but no luck doing that. Help!.

At lunchtime today I started getting emails with no header sender or other info. It is just blank and the emails dont show just a load of source info in the message body.

I have lost the indicator in the folder pane showing which folder I'm in. It used to have a small color tab in the folder pane on the left hand side. Indicating that the folder was selected. Any ideas to get it back? Thunderbird 140.3.1esr (64-bit)

I tried to use Thunderbird today,.. to find the interface was broken, menus were blank, so no ability to look at anything., and error message inferring there was a menu config issue was all that was shown. I duly removed Thunderbird as a snap install, which took a long time as it seemed to be making a backup to somewhere. I then reinstalled Thunderbird 128.11.0esr (64-bit) on my ubuntu 24.04,.. having setup the isp email credentials,.. all seemed fine,.. I then proceeded to import what I assumed was my old local folders... And this is where things went wrong, as I seem to have lost all my archived 2025 emails,.. I say somewhere,.. as I don't seem to be able to find them, I have used the 'find' command to locate anything with 2025 in the file name,.. but without success. At the moment I have a multi-structured 'local folder' entry, but nothing with 2025 in? I anyone able to shed some light on what I may have done wrong Many tx

Even though I've never changed my settings aside from the first time I changed them to my preferred settings, for whatever reason, Firefox no longer opens links I tap on in external apps. I changed the settings to do it that way the very first time and it worked fine up until a little while ago. Now, the only way it opens a link in the external app when I tap on it, is if I tap and hold, and then choose that option in the pop-up menu. As I said, in the settings it IS set to open links in external apps, but it doesn't do it anymore.

Every time I open thunderbird I get a blank screen with this message, 'Edge: Too many requests' over the top of the thunderbird screen. This screen stays on my desktop after I close Thunderbird and I have to change my screen resolution in order to close the screen. Can you help please? Martyn Smith

If there's one thing I can count on, it's that the next version of Thunderbird will be more buggy & unstable that the previous version, and v 140 certainly does not disappoint in that category. It crashes & closes multiple times per day. Any time something else may be using a lot of resources, Thunderbird freezes up and if I click on it, the app crashes & closes. At least the previous just stayed greyed out until it was able to complete the task and didn't crash & close. Great job Mozilla.

Hello, I received an email from you asking me to change my Firefox password for account security reasons. When I changed it, all the data synced in Firefox with my email was deleted. This upset me greatly because I lost important data and saved websites. Please restore the deleted data. Thank you.
