Hi all. I had a hard drive failure and managed to mostly clone the old drive to a shiny new one. There were errors logged during the clone and TB appears to be a victim of those errors.

Win 11 x64.

When I launch TB I get the icon on the taskbar but no main screen. If I hover over the icon I see a small box with the TB logo top left where you’d expect it, and Home next to it. Clicking it has no effect. TB appears to be functioning because new emails are being filtered according to the Rules, as witnessed on my phone.

I tried reinstalling 115.11.1 with no change. So obviously somethings fubar with my profile. What is the best way to proceed? Obviously I’d like to avoid having to set up all my email accounts plus the associated rules etc if it’s possible. I use IMAP if it’s relevant.

Thanks in advance, Tony

My emails do not download into my email "in" box as they used to do. I get the following message when I try to log into my emails.

Warning: Potential Security Risk Ahead

Thunderbird detected a potential security threat and did not continue to live.thunderbird.net. If you visit this site, attackers could try to steal information like your passwords, emails, or credit card details.

Can this be fixed? Can you help me to fix this problem? Thanks, Michael.

Hi, I have been using thunderbird with two accounts. One day one account decided that won't get new messages, so I deleted that account, tried to add it again and it is showing me mistake: Unable to log in at server. Probably wrong configuration, username or password. I am 100% sure, that all the credentials are correct. Could you please try to help me?

Recently Firefox always has the error "failed to check for update". I have tried restarting my pc and running as admin. I am on windows 10.

I have been able to manually install the latest version by installing it over the top of my current install, how can I fix the error to be sure that my browser will auto update?

Thanks

Dear fellows,

I did lost all history data after a previous update, my user got corrupted data and somehow I did manage to import the info into Edge browser. To my surprise after I reinstalled a clean Firefox, it only imported back 3 months of browsing history. Topically, average user keep a computer 3-4 years.. I don't know from where developers came with the idea of limiting to such a shot interval. I have thousands of browsing history links from more that 10 years kept and I need them all.

Tried to increase the number from about:config, but there is an option only for Chrome which I never used and always hate :)

I did installed Chrome to convince myself about it's ingenuity, even if it was not necessary. It does have import option only from Microsoft Explorer, no Edge.

If there is a solution for importing a longer period and high number of entries, please share it.

I'm not an IT expert, but I can manage consoles if there is an even deeper option to modify config files.

Thank you in advance!

Firefox Installer.exe starts and, after some time, gives that error message: Ihr Profil "Firefox" kann nicht geladen werden. Es ist möglicherweise nicht vorhanden oder ein Zugriff ist nicht möglich.

i SET UP THUNDERBIRD ON MY NEW COMPUTER, SUCCESSFULLY, BUT THREE DAYS AGO MY WEB HOST/SERVERS UPGRADED THEIR SYSTEM. i SPENT THREE DAYS SORTING OUT NEW SETTINGS. CONFIGURATIONS, PASSWORDS, ETC, TO GET IT ALL WORKING, IT WAS DIFFICUL BUT IT NOW WORKS. HOWEVER, I HAVE MANY FOLDERS OF MAIL ,AND MAIL NOT IN FOLDERS, IN THEUNDERBIRD ON AN OLDER COMPUTER. i WANT TO IMPORT THOSE FOLDERS OF MAIL, AND ADD THEM TO MY NEW COMPUTER THUNDERBIRD INBOX SET UP, BUT I DO NOT WANT TO IMPORT THE OLD SETTINGS AGAIN!" THAT COULD BE A DISASTER. I JUST WANT THE MAIL AND THE FOLDERS. ALL THE VIDEOS i SEE ARE TO IMPORT THE OLD SETTINGS AS WELL. CAN I JUST EXPORT/IMPORT THE ACTUAL MAIL FOLDERS AND MAIL, AND NOT SABOTAGE MY HARD WORK BY CHANGING ALL THE NEW SETTINGS AND PASSWORDS BACK TO WHAT THEY USED TO BE IN THE PROCESS?? IM NOT THAT TECHY; WOULD GREATLY APPRECIATE YOUR ADVICE. THANKS, STEVE

Hello, I have problem with firefox. When I try download from facebook page files .docx, .xlsx (Microsoft Office) Firefox automatically download it as PDF and file is broken. I don't know how to repair this. Please help, it is very frustrating.

I have added my gmail account to TB and it downloads all the folders and emails correctly, but as soon as I try to move an email with an attachment from a local folder to a folder on the gmail acount I get "Connection to server imap.gmail.com timed out" errors.

i need some help with my firefox browser. all of a sudden my firefox browser wont download any files from anywhere but if i try to use the save image as on an image firefox would download them. weirdest thing is other browsers are fine when downloading files.

Prior to update 125.0.1 corporate intranet users could download PDF files from our Line of Business applications / Webpages. Today after the latest update the PDF files download but are corrupted. The site was added to the trusted webpage without improvement.

Adobe Acrobat Reader could not open ********.pdf because it is either not a supported file or because the file has been damaged

I recently setup a new Windows 11 computer and installed the latest version of Thunderbird. I have two email accounts. The gmail account presented no problems. When I tried to setup the AT&T account I first obtained an authentication password and setup the account. While I can send email just fine, the account will not download any email. When I go on the AT&T server directly, there are new, sent and deleted email there. The server settings are set to SSL/TLS and OAuth2. What else do I need to setup before I can mail from the AT&T server?

On Sunday 2nd June I removed and then reloaded Thunderbird, which ceased to function the previous day.. Now I can't send but can receive e mails, and it has lost my entire e mail address list. I need this list to be restored asap, please, so I need advice.

Hello,

We have a client using Azure Virtual Desktops. Most of the users prefer to use Firefox. We are having an issue that anytime we update Firefox and reimage the virtual hosts. When the users login they get a new Firefox profile. We have to remote in and copy their old profile data to the new profile.

Is there a better way for us to handle Firefox and profiling in and Azure Virtual Desktop deployment?

Hi, so sorry for the delay and inconvenience caused by this matter, I’m new to all of this and not sure what I did or have done to create this giant mess I have for myself, but I need some help!
