on my laptop the firefox search engine randomly changes to one that I don't even have checked as "search shortcuts" but are still on my "default search engine" list for some reason (but never chosen by me

Where do I input my recovery Key to get my account back? I recently had to get a new mother board and hard drive on my laptop. In the process, it wiped out my Firefox. I have reinstalled Firefox and have my previous Recovery Key to get my bookmarks passwords but can not locate where to enter the recovery key to do this. All I can seem to find is how to create a recovery key, not where to enter an already existing recovery key. Please help.

Previous solution: switch browser.newtabpage.activity-stream.improvesearch.handoffToAwesomebar to false does not work anymore.

Please help.

As of today, I am unable to link to, or log onto, my email server - gmx.com..... Have never had a problem until today.

Today, when I opened up Thunderbird, ALL my email accounts came back with an error message stating that the login to the server failed (see attachment). I don't know what happened.

I checked all of my settings, and they are all correct (according to GMX), I tried to re-enter my passwords, and even re-booted my computer in the off chance that there may have been a booting issue. Nothing helped.

Can someone tell me what's going on? Why is Thunderbird all of a sudden not linking with the email servers? How do we fix this when all of the protocols are correct - and have been all along? Any thoughts, suggestions, or advice?

Thank you....

Hello,

I have defined about 45 simple filters to get rid of spam. They are all based on keywords found in subject or sender.

All of them are enabled and set this way :

Apply filter when : _ Manually Run X Getting New Mail ( Filter before Junk Classification ) _ Archiving _ After sending _ Periodically, every 10 minutes.

Perform these actions : 1. Set Junk Status to : Junk 2. Move Message to : "super-junk" folder 3. Mark As Read

See example in attached image.

PROBLEM : They do not run automatically when new emails are received. But if I run each of them manually, they work.

QUESTION : What is wrong ?

Thanks !

I am seeing pop up ads like these on the lower right corner of my screen since I updated to windows 11. I've never seen this with windows 10. Microsoft is telling me these are coming through my browser. These are not when I am in a web site and get the pop up to allow notifications, I always say no. These come @ 1 per week or less and I don't seem to be able to stop them. Is there a setting in firefox that will stop them or is this a microsoft issue? thanks brian

bold text I have tried restoring my system to a previous date. I did receive those Emails. Today, I've not received my Email messages. I have tried you help resources and have been able to get Thunderbird to run as before. I would appreciate any assistance that you could give a seventy-six year old user.

I have a Windows 11 operating system. I tried browsing/uploading a couple email messages describing providing more information but wasn't successful. Can you help me ?

For no obvious reason, Thunderbird started complaining about my existing configuration to mail.com. I tried changing passwords, I tried rebooting the computer, but nothing would work. I kept getting the "invalid password" popup when trying to connect. I've double-checked that mail.com is still working (I can access all my email from the web client no problem).

So, eventually, I deleted the account from Thunderbird altogether and now I'm trying to recreate the configuration. Thunderbird recognizes mail.com and correctly deduces the server configuration settings, but it will not connect. When I try to add the account I get this message:

"Authentication failed. Either the entered credentials are incorrect or a separate username is required for logging in. This username is usually your Windows domain login with or without the domain"

Why on earth would a "Windows domain login" be needed for a web-based email location?? When I had the configuration set up before, all I had to supply was my email address and password.

Something in Thunderbird has changed and I can't figure this out.

Meanwhile, I have about 10 other email accounts set up on Thunderbird and they all seem to be working properly.

Would sure be nice to find a solution so I can get my mail.com account back on Thunderbird.

Thanks for any help you can provide.

When I search for a name in Thunderbird mail e.g Lennart, nothing from 2026 comes up, only older mails from 2025-12-31 and backwards. if I search on his e-mailadress, e.g l.name@ppost.se it finds avery mail. What is wrong?

Von der Erstinstallation war ich gewohnt, dass von oben nach unten die Darstellung der Ordner wie folgt war: Posteingang / Entwurf / Gesendet / Archiv / Spam / Papierkorb / Local Folders /Postausgang / Unbekannt Nach der neuen Installation, die erforderlich war (Rechnerneuinstallation) ergab sich folgendes Bild von oben... Lokale Ordner / Papierkorb / Local Folders und dann alle meine selbst erstellten Ordner am Ende dieser Aufstellung kam die Zeile mit meiner web-Adresse xxxx.xx@web.de dann Posteingang usw. siehe oben aufgeführt Damit liegt der Posteingang am Ende meiner Ordner Auflistung und das ist über den unteren Monitorausschnitt hinaus, diese Situation ist für mich untragbar und deshalb werde ich wohl auf ein anderes e-mail Verwaltungsmedium umsteigen müssen. Eine Kopiermöglichkeit um die Ersteinstellung zu erreichen war kläglich gescheitert und jetzt ist das Durcheinander noch größer beste Grüße B. Bein

I have a Brother DCP-L2550DW printer that is connected via a network cable. Any other browser, i.e. Edge or Chrome, seem to be able to connect and print just fine. Firefox fails to print and there is no information about why. I have checked Event Viewer, turned off all the extensions, tried the about:config to reset printer options. Every single suggestion I've found so far fails to fix it. I have a great deal invested in using Firefox (bookmarks, etc.) so I'd like to keep it as my default browser, but not being able to print is SO annoying. Any suggestions?

I am using the Thunderbird software (140.7.1esr 64-bit) for mail merge purposes on a Windows 11 operating system. However, when I start the mail merge process, it begins initially but then automatically disconnects before completing the task.

Due to this issue, I am unable to complete the mail merge properly. Kindly look into this problem and provide a solution as soon as possible.

Thank you.

I don't recall clearing the history.

Also, starting a few days ago, if you type it into the search bar on the homepage, it will drop to the top. What is the cause of these issues? I'm using Windows 11.

TB on Windows

Prior to TB 148, OAUTH worked for POP3 access to: Gmail, MS Outlook, and Yahoo.

After TB 148 upgrade: OAUTH to Yahoo fails, subsequent log-in page also fails. Both OAUTH to Gmail and OAUTH to MS Outlook still work fine.

Rolled-back/Reverted to TB 147.0.2 -- OAUTH to all works fine, as it did previously.

Note: YahooMail seems to have other problems. But I was able to confirm successful OAUTH and POP3 to YahooMail after reversion to 147.0.2.
