My computer recently updated to Thunderbird 155.0. The Local Folders did not move along with all my contacts. I have backed up mu Local Folders and contacts into a file into a file. Using the forum I have cut and pasted all of these into the Local Folder in the new Thunderbird but they are not there in the new Thunderbird. Please explain how to restore them in the new Thunderbird. I would suppose i will have the same issue with Address Books and would appreciate help there as well. Many thanks for your help!

Trying to solve aperformance problem I tried to move my profile from C:\Users\Peter and Carol\Profiles\sjig3laj.default to "C:\Users\Profile\." -- when that did not work, I was unable tomove back to the original location, TB telling me "Local directory path ... is not suitable for message storage". How do I get back to the config that worked before ? (was just slow)

I’m honestly fed up with this issue. **How is this even acceptable?** Every time I update Firefox, or sometimes completely randomly, my entire Firefox profile gets logged out.

And it’s not just my Firefox account. **All the websites and services I’m logged into get logged out as well — including my email accounts and other websites where I have active sessions.** I then have to go through the ridiculous process of logging back into everything again.

This has happened **8 TIMES already.** Eight times! This is not a one-time bug or a minor inconvenience anymore. It is seriously disrupting my work and wasting my time.

I need to know **WHY Firefox keeps doing this** and why an ordinary browser update is apparently capable of destroying all my active login sessions. If this is a bug, it needs to be fixed. If it’s caused by a setting, update, or profile issue, then tell me exactly what is causing it and how to stop it.

I’ve used Firefox expecting it to reliably keep my profile and sessions intact. Having to repeatedly log back into my email accounts and every other website is completely unacceptable.

• • Please don’t just send me a generic “restart Firefox” or “clear your cache” response.** I’ve already dealt with this issue 8 times. I want an actual explanation and a proper solution.

Please take this seriously and investigate what is happening to my profile and login sessions.

Thanks.

Hello. Thanks in advance. I spent a couple of long evenings deleting a few thousand sent emails from Thunderbird in order to free up some memory on my notebook computer and then intended to create a new backup profile. However, when I tried to do so using the Thunderbird Export tool an "unexpected error" occurred and I discovered that there was no longer a Thunderbird profile folder in Windows/Users/[my name]/appdata/Roaming or Local. When I used the Troubleshooting Information tool to look for the folder under Application Basics/Profile Folder, clicking on 'Open Folder' did nothing. The location is seemingly 'unavailable' for no apparent reason. Thunderbird still opens and closes normally, I can send and receive emails and all my emails are still there. I have an older backup profile stored on a removable disc, but it pre-dates the mass deletion of sent emails. My question is: if I install Thunderbird on a different PC and import this older backup profile, I presume all the emails I've just painstakingly deleted off my PC will reappear, but can Thunderbird connect to the server and download my stored emails as they were most recently saved (without the thousands of unwanted sent emails) so I can create an up-to-date profile? Thanks in advance for any advice.

When I opened Thunderbird two days ago it came up with the following message: To use your current email address, fill in your credentials. Thunderbird will automattically search for working and recommended server configurations. It asked for Full Name; Email: and Password. Fearing it was a scam I filled in my server settings manually. My server is Centurylink but my email address is embarqmail.com so when I filled in my info the send was smpt.centurylink.net port 587 (which was fine) The problem was with receive: I guess my old setup was pop.embarqmail.com port 110 and I put in pop.centurylink.net port 995 which is what Centurylink's website called for. Well this one worked and it downloaded 800 messages but no saved folders and the Thunderbird screen layout looks different from the one I am used to. A few minutes later the pop.embarqmail setup downloaded the same messages but still no saved messages. It looks like I have 2 profiles. Did the last one I entered override the old and wipe out files I had stored. Is there a fix for this mess I have created and can I retreive my old folders and messages? I tried doing a system restore and it didn't work due to corrupted files. Oh, I'm still using windows 7. Thanks

When I restarted firefox on my mac, it opened up a new window with no profile/bookmarks as if I was starting firefox for the first time. It doesn't have my old profiles. I suspect there's a "hidden" version of firefox someplace that does have my profiles, but I'm not opening the right version -- which is why it is opening as if I'm starting anew. My dock often shows two firefox icons, but there are not two firefox applications in my applications folder. The only one available on the dock right now is the one that opens a blank profile. And if I open firefox from the applications folder, it also opens a blank profile.

Copilot has prepared a message for me: Subject: Thunderbird always loads corrupted profile and ignores new profiles

Message:

Thunderbird is stuck loading the same corrupted profile and always shows the welcome screen, even when I create new profiles.

I used the Profile Manager via thunderbird.exe -p and created new profiles (“Clean” and “Clean2”). Both profile folders exist in %APPDATA%\Thunderbird\Profiles. However, Thunderbird still launches the same original profile every time.

Even when I select “Clean2” in the Profile Manager (with “Use the selected profile without asking” unchecked), Thunderbird ignores the selection and loads the old profile. Safe Mode (thunderbird.exe -safe-mode) also does not disable the welcome module.

This appears to be a profiles.ini corruption or a profile lock issue, because Thunderbird is not switching profiles even though the Profile Manager shows the correct selection.

Could you advise how to repair or reset the profile configuration so Thunderbird will actually load a new profile?

Thank you.

I have a previous Thunderbird account, which resides on another computer. On my current Desktop, I downloaded Thunderbird, went to open and it says "Your Thunderbird profile cannot be loaded. It may be missing or inaccessible." I went this route because my original Thunderbird has many customized Files to which I put emails into. I can't figure out how to recreate that profile as your instructions are quite impossible to follow. Remember, most of your users are like me, a bit under the standard as far as programming skills. So, how do I get either: my original profile to be imported to my new computer, or, better, just open my new Thunderbird so I can use a different, newer set of email addresses? This is my preference. Please advise.

I have a profile set that uses IMAP and need to change this to POP. I have tried changing the settings and tried creating a new profile by exporting folders and files but nothing is working correctly.

One problem I have is that in the IMAP profile I now have a second email address that is the same address name but is a POP setup. This is confusing. When I use the POP email to export and then import into a new profile I again get two email addresses in the folder panel of the new profile and one of them does have folders but they are empty.

Below is a screen shot of the original IMAP Profile. The upper address has folders but they are now blank because I pasted them in the lower address. I have tried selecting/highlighting the lower address for exporting but when I do I get the two addresses but the folders are empty/blank.

Thank you for any help!

Hi, When I click on the profile icon in the top right, I can no longer edit one of my profiles ("School"). I can still open it, bookmarks/passwords are still there, but I have to log back into everything and in the School profile, I can't switch back to "Personal" by clicking on the profile icon like normal.

I'm on Windows, and yesterday was showing something on my laptop to a mac user. They kept right clicking or something, and some tabs greyed out before I had to just close firefox. When I opened it again later using the "School" profile shortcut on my desktop, it opened a blank/new page. I was able to sign back into the account since I have sync on, so my passwords/bookmarks/etc are there, but I can't edit it any longer and can't make a new profile shortcut for my desktop. And when I open Firefox from my taskbar, it automatically opens my Personal profile instead of letting me choose which. Any ideas on what might have gone wrong & how I can fix it? Thank you!

Hello.

Has the profile logic been thought through?

When I set a default profile, I would expect

A) all new pages open into the default B) That firefox always opens the default without request.

This does not happen.

firefox.exe -P is set correctly.

Any ideas? I feel after the profile choice was improved, the basic logic may of been broken.

Thanks

I'm getting frequent popup messages from McAfee, my email threat detector, that they've detected and stopped a threat, but none is identified. McAfee's chatbot wants me to create a new profile and add my email accounts to that profile. Will I lose access to all my currently saved email messages and calendar information?

I have followed the instructions that several people give to transfer my existing Thunderbird installation to a new computer where I have just installed Thunderbird. That is I copied the Thunderbird folder and put it in the Roaming folded found in %appdata%. Both computers are on Windows 11. When I open the new Thunderbird, it does not recognise it. Furthermore, in Help>Troubleshooting information>Profile folder when I click to open the folder, it looks for a folder that is not in my previous Thunderbird installation: qr19mupe.default-release instead of the one that came with my imported Thunderbird folder. Has this happened to anybody and found the solution? Can anybody help please?

TL;DR: I am dumb, but not an idiosyncratic web browser user, and it was too easy for me to accidentally permanently delete all of my browser data. Deleted profiles should be moved into system trash when deleted, not rm'd entirely.

I have never used "profiles" and somehow, after updating firefox, seemed to have created one. I have no interest in using the feature, and therefore went to delete the new profile and disable the feature. Somehow, I instead deleted the profile I had implicitly been using all along. I clicked too hastily through the warning about deleting files, because it simply did not occur to me that deleting something related to this net-new feature should clear all of my *old* data. My goal was to restore the experience I've had in firefox for years (without profiles), but because I failed to adapt to the new feature, I lost everything instead.

I apologize for maybe shouting into the void about this, but I am posting on the off chance that this will reach someone who's involved in the implementation of these features and can save some other dumb person like me from making the same dumb mistake. It's quite painful to suddenly lose years of accumulated bookmarks, extensions, history, etc. The easiest and least intrusive solution would be to always move profiles into system trash when they are deleted, and never permanently delete them.

My Thunderbird was working fine today, all messages received, could send/receive email and all parts of my profile that I had set up (ie custom archive folders) were present and had emails.. I did a Windows update and when I reopened Thunderbird there was a pop up prompting me to login to my yahoo email. I did so and now everything is gone, all folders are empty - no emails and none of the unique folders I had created. The only thing that I can tell is still present is my address book. I am also unable to send or receive emails. When I try to send an email (to myself or anyone else) I get a pop-up "The mail server responded: Request failed; Mailbox unavailable. Please verify that your email address is correct in your account settings." I checked and the email listed is correct, the one I have been using my entire life. I also checked my Server Settings and they appear to be correct. (I have a cox.net email address which I transitioned to yahoo several years ago as instructed by Cox, as Cox no longer supports email - everything has been working perfectly until today) I also see there was a Thunderbird update done at 5:53PM today which would have been the same time I did the windows update (Thunderbird 153.0.3esr). I sent an email to myself from my yahoo website email and it never arrived in my Thunderbird Inbox but it DOES show in my Thunderbird "Sent" folder. I do have a Thunderbird backup ZIP file but unfortunately it is about a year old so obviously won't have some stuff I would not like to lose. Thoughts?????

all my icons keep wanting to sign me in i lost all n y icon mey extensions are there are enabled

enabled but not in  toolbar   ehat is going on     firefox is screwed p everytime  i hit any icons  i have to  reload or reinstall please help
