When i try and accept an e-transfer using Firefox, I'm getting an error message "Application error: a client-side exception has occurred (see the browser console for more information". I've always been able to accept e-tranfers in the past.

When encountering a problem with a new release and wanting to downgrade back to an older (working) version - especially if some plugin I depend on hasn't been updated yet. The current version is well marked, but it would be helpful if the older versions had a subject line like "Release 115.x.x (github commit id)" so we can do better than walk back one release at a time. All flatpak examples for rollback show meaningful subject lines, but Thunderbird and other flatpaks I actually use don't seem to.

I have two computers, one older with TB 115.9.0 32 bit, pop. The other has 115.9.0 64 bit, imap, same email address. I have tried to merge them, but when i do the Thunderbird Import folder has zero messages and no subfolders. I also tried changing the old TB to IMAP, didnt work: "configuration problem". Any help would be appreciated.

I have a thunderbird account but switched to gmail and now wish to return to thunderbird but error message 400 from Google appears each time.What do I need to do - in simple terms pls

Hello, I have two email addresses, one personnel, one business. The other night, Thunderbird asked me to download an update. Since downloading the update, all my business emails and subfolders are gone and have been replaced by my personnel email address and subfolders. (in the left hand pane - pic attached) The business emails and subfolders are on my main server yahoo, but are not on my Thunderbird program. Can someone help me to recover the business email address emails and subfolders? Thank you.

Hello, I've installed Firefox twice in the last couple of days (Windows 10 - I think) and I continue to receive messages that say I need to install the latest version.

Do you issue updates daily, or is there something wrong with my Firefox installation or is it something else?

Thank you.

Until the 9th of april I had no problem since then I keep on getting the message: login to server imap.tools.sky.com user namemorgandavid33@sky.com failed

retry or enter new password.

I contacted sky and I did change my password on their advice and I still cannot login. How do I get thunderbird to accept this new password. Or is there another issue with logging in?

The Sky.com email is now provided by Yahoo. I can access my emails there but I prefer Thunderbird and have used it for some time now. Thank you for your help.

I have Firefox 124.0.2 running on Windows 11. For some reason, I can't update Firefox. When I manually download the update file, it appears to run Ok, but the version doesn't change. If I go to settings and click on "Check for Updates" is comes back and says Failed to Check for Updates. How do I fix this?

Originally reported on April 11th /questions/1444593: I have Windows 11 and the Firefox 124.0.2 browser. I cannot update to the latest version of Firefox. I receive an error message "Failed to update". I've uninstalled and reinstalled the browser, ran the install utility selecting update, nothing seems to work. Please help

I did an Upgrade to a version of Firefox that would bypass those "Your Browser Is Not Supported" messages that apparently come from "Cloud-flare." I figured [naievely!] that my addons would "port" to the upgrade. They didn't. Is there any way [e.g., a putative backup file, perhaps] that would allow this?

Thanks in advance...!

Have two computer with same email. My Wife's computer password got corrupted and unable to get messages. I deleted TB and deleted any reference to Thunderbird in the registry. Turn off and restarted PC, downloaded new install and run and all the setting from before automatically were in place and still could not get pass the password issue. My computer does not have any password.

My wife's PC, under setting, does not have any saved passwords or a Primary password or even the "Use a Primary Password" checked. If it is checked there is nothing there. It just will not get passed the password issue being always asked when trying to "Get Messages".

How do you get rid of all the infor, setting, password requirements and to be able to restart with a clean Thunderbird install or get passed the password issue? Making my brain hurt.

I have several users who are migrating email from Outlook, and they want me to confirm if the Thunderbird export will bring over:

• drafts
• sent mail
• deleted mail
• any subfolders in the mailbox

Thank you!!

Hi, I am running Thunderbird v. 115.9.0 on Windows 10 on my desktop. I have been forced by Rogers in Canada to migrate my internet service from their legacy internet service to Rogers Ignite with its Ignite (Comcast) gateway. My email accounts were supposed to be migrated automatically, but, for reasons unknown, were not, and a tech support representative had to migrate them from the old legacy service to Ignite. After that was done, I opened Thunderbird, and was asked to authenticate my 2 Rogers/Yahoo email accounts, one of which is my primary account, the other a secondary account. I was asked to authenticate the secondary account first, which went well. I then clicked on my primary account in the left-hand pane and was again asked to authenticate, but the dialogue box showed it was for the secondary account. Thinking that this secondary account authentication was just being repeated for no particular reason, and not thinking that the email address in the authentication request box could be changed, I clicked Agree. My primary account is now showing the exact same emails as are listed in the secondary account, and I'm extremely concerned that I will not be able to recover all of the thousands of emails in my primary account, many of which are business-related. When I log into my primary account on the Rogers/Yahoo mail website, the emails in the primary account are still showing, so I know they are still on the Rogers IMAP server. However, I really want to continue to use my primary account on Thunderbird. I'm not sure if I should delete the primary account and recreate it - the Rogers support tech said that deleting the account may result in an issue where my current password for a re-created primary account may not be recognized, so I'm leaving things as they are until I hear back. It the advice is to not delete and recreate the account, what steps can I take to recover the emails on my primary account in Thunderbird. Thanks in advance for any help and advice that can be provided. LES.

I have suffered a total hard drive crash. Fortunately, I had a complete disk image saved to iDrive. After many hours, I was able to find my profile in the appdata and watch yesterday as my 10000+emails (approximately 10 years of emails!) streamed into my new PC from my Comcast/Xfinity account. However, when I went to access my TB account this morning only a small percentage of the emails that downloaded yesterday were accessible. My TB email account is essentially the file drawer of my life. I want and need to be able to access all 10000+ on a daily basis. What did I do wrong? How can I fix this. Thank you so much!

Old computer: Windows 10 Pro, 64 bit Thunderbird 115.10.0 32-bit (Don't know why it's 32-bit version on a 64-bit computer or whether that's relevant)

The Profiles folder is here (with 5 profiles): C:\Users\<User>\AppData\Roaming\Thunderbird\Profiles

The new computer is Windows 11 Pro, 64-bit I just installed Thunderbird (V115.10.0 (64-bit) on the new computer.

On the new computer, the Profiles folder is here: C:\Users\<User>\AppData\Roaming\Thunderbird\Profiles

I followed the directions here https://support.mozilla.org/en-US/kb/moving-thunderbird-data-to-a-new-computer

I basically took the Profiles folder that came with the Thunderbird installation, renamed it (Profiles.orig) and copied in the Profiles folder from the old computer in its place. When I start up Thunderbird, I get this error message:

           Your Thunderbird profile cannon be loaded.  It may be missing or inaccessible

What am I doing wrong? I've updated Thunderbird on the old computer and copied the Profiles folder over to the new computer again. Same result.

Could it be 1. an issue with the user name on the old computer is different than the one I'm using on the new computer? 2. All files on the new computer are set up as local (the user on the old computer started out as a Microsoft user but I made it local so as not to have to use OneDrive).

I'm stumped. Any help will be very much appreciated. If you need any more details I'm happy to provide them.

Hello, I use Thunderbird portable. I imported as Imap an existing account at Infomaniak.com but all the personal folders and subfolders were missing. No problem, just right-click on the account and choose "subscribe" ("s'abonner" in French), ticking all the proposed folders. So in IMAP it works, but if you set the account as Pop3, the "subscribe" function doesn't appear. I need Pop3 for an account to be imported into Thunderbird. How can I do this ?

Thanks for your help !

Sadly, my old Windows 10 PC crashed, and I'm migrating to a new computer. I have a backup of the old default profile folder (9k7faw1z.default), but not of the entire Profiles folder. I have tried to import this old default profile using the import function in my new Thunderbird install on my new Windows 11 computer.

Alas, I get the error message "Import failed unexpectedly; more information may be available in the Error Console." I looked in the error console, and it's empty.

Is there a better way to import my old data from my old default profile folder? It's 3GB of valuable data and I'll be in a pickle if I can't access it.

Thanks very much.

We've enjoyed T'bird on this PC for several years. About a year ago my wife got a new laptop; it came with Outlook as the default email program. It worked only fairly well, but now it has pretty much bitten the dust. I installed T'bird for her and it's working fairly well, but with a couple minor bugs. First, there is no address book in it and also the menu bar across the top is missing. HELP!!!!!

We have been using Thunderbird with a Cox email account. Cox has just transferred all its customers to Yahoo. I want to use Thunderbird with Yahoo. How do I set that up?
