I'm using the latest version of Firefox on macOS Tahoe. Over the past 2–3 days, Firefox has started behaving unexpectedly.

Issues:

   Firefox automatically creates additional Dock icons while I'm only using a single Firefox window. Even if I remove the extra icon, it reappears after some time.

   When I open a different Firefox profile, it launches under a new Dock icon instead of using the existing Firefox icon. As a result, I end up with three separate Firefox Dock icons simultaneously.

   Firefox also fails to play pronunciation audio on some dictionary websites (e.g., JapanDict). Clicking the speaker icon produces only a brief click with no spoken audio. The same pronunciation works correctly in Safari, suggesting a Firefox-specific issue.

Expected behavior:

   Firefox should use a single Dock icon (unless intentionally running separate app instances).

   Different profiles should not create unexpected duplicate Dock icons.

   Pronunciation audio should play normally, as it does in Safari.

Environment:

   macOS Tahoe (latest version)

   Firefox (latest version)

My Windows 11 PC crashed but i was able to recover copy of my firefox profile. I copied previous profile folders and i am able to access those profiles using firefox.exe -P command.

But profiles don't show up in the new profile switcher. How can i restore them to modern way profiles work.

i don't want to setup accounts and sync for my profiles.

On T-Bird start up I'm given a list of (originally) four Profiles. Currently I only use Profile Three, but on start=up today it is not there. Doing the usual searches does not list it, only 'default', 'new user' and 'profile two'. Is there any way to recover it?

This is a follow-on to a question I asked yesterday. I appear to have accidentally deleted the main Profile I use for email. However - thinking back - I'm 99% sure I clicked the 'Don't Delete Folders' command. This supposedly deleted the Profile name BUT retained all the information in 'storage' - but where is that located?

Until I close the following message that appears on Firefox Screen other apps are slow or won't open.

Box with Red X - This profile was last used with a newer version of this application. Please create a new profile. OK

I followed the directions to CREATE A NEW FIREFOX PROFILE.... ,, created as Personal #1 & Personal #2 perhaps I did something wrong......Help!!!!

My current Thunderbird profile has been created dirctly in ...AppData\Roaming\Thunderbird. <Profiles> does exist but not contain any recent files or data. How do I restore a proper data structure without losing any emails, settings or other data?

The screenshot shows the present structure

My Windows 11 was recently reinstalled to factory settings, which uninstalled Thunderbird but saved my mobx files. I used Thunderbird exclusively to view older emails that are stored on my PC as mobx files. I do not use Thunderbird as an active email client. I reinstalled Thunderbird, but have been unable to get it to find my mobx files that are stored together in a folder.

My firefox profile keeps showing as repeatedly being deleted then saved in one drive - see screenshot. It's using a lot of memory anyway - nearly 3GB currently with 10 tabs, i've tried most fixes on https://support.mozilla.org/en-US/kb/firefox-uses-too-much-memory-or-cpu-resources

I don't think it used to do this repeated profile deleting thing - any suggestions?

I have been trying to transition my Comcast.net email to Yahoo email mandated by Comcast. I have been using Thunderbird as an POP account for years with the comcast.net account. When sending emails through Thunderbird, I was prompted to enter my Comcast.net password. It worked fine. With the transition to Yahoo, my email password did not allow the Yahoo email to flow thru to Thunderbird. Yahoo stated that I need a four block with spaces, and 4 digits each block, Yahoo APP System generated password. When I keyed in that APP Password, everything would flow through. one time, Next time I want receive or send and email, I needed to key in the App Password. Yahoo stated that once entered it I would not have to use their system generated APP Password. Unfortunatley there was nowhere to save that password in Thunderbird. Yahoo then told me to remove and re-enter my Yahoo Account in Thunderbird.

I deleted the old profile that was originally my profile for Comcast.net and editied to the new Yahoo details, and started reestablishing that profile with the Yahoo Incoming Mail and outgoing smtp server information, Unfortunately upon re-entering my Yahoo information I have lost of of the existing emails/folders. that I had in Thunderbird. Now what do I do to recover all of those old emails & folders?? Help! I still have to use the original email address that has been converted to Yahoo. Any way to go back to Comcast to recover the data that consituted those old emails, or are they just lost?

I have been using Mozilla Thunderbird for many years without any issues.

A few minutes ago, I used Thunderbird as usual and then closed it. When I tried to open it again, it would not respond. I restarted my Windows 11 laptop, but after rebooting, Thunderbird opened as if it were a fresh installation. None of my email accounts, settings, or data are there.

I signed in to one of my email accounts, hoping Thunderbird would automatically recover my previous accounts and settings, but nothing happened.

I am using Windows 11 and Thunderbird version 140.13.0 (64-bit).

Could you please help me recover my existing Thunderbird profile, email accounts, and data? I would greatly appreciate your assistance.

Thank you.

Hello,

I need help recovering my old emails from Thunderbird.

I am using a POP account. Recently, I changed the message storage location from the C: drive to the F: drive. After doing this, Thunderbird only shows recent emails, while my old emails are missing.

Here is what I have checked:

The mailbox files still exist on the F: drive. Inbox file: approximately 1.1 GB Sent file: approximately 1.18 GB I also have a complete Thunderbird profile backup of approximately 2.73 GB. The profile contains prefs.js, the Mail folder, and all profile files. Some account folders such as: pop.accessarchitects.in pop.accessarchitects-1.in pop.accessarchitects-2.in have Inbox files that are 0 KB. However, another mailbox file named Inbox is about 1.1 GB, which appears to contain my old messages. Thunderbird downloads and displays new emails correctly, but it does not display the old emails. I previously had around 60,000+ emails organised into many custom folders such as Contracts, Bills, Axis Bank Statements, Notifications, etc. Some mailbox files still have large sizes, but Thunderbird does not display their contents. My folder structure F:\Mails\

   Inbox (1.1 GB)
   Sent (1.18 GB)
   Inbox.sbd
   Local Folders.sbd

Inside Local Folders.sbd, I also have mailbox files such as:

Inbox (~642 MB) contract & bill (~778 MB)

The data appears to exist, but Thunderbird is not recognising or indexing it.

My Questions How can I reconnect these existing mailbox files without losing any data? Is there a way to rebuild the indexes so Thunderbird recognises the old messages? Could the issue be caused by an incorrect profile mapping after changing the storage location?

I have not deleted the original mailbox files, and I have a complete profile backup available.

Any help would be greatly appreciated.

Thank you.

I have followed your instructions at https://support.mozilla.org/en-US/kb/moving-thunderbird-data-to-a-new-computer and gotten nowhere all day. on it. You have "Profile Folders", a folder called "Profiles", a bunch of profiles (folders) inside the Profiles folder and profiles in Roaming and in Local paths. When I get the old profile 'k41******' copied to the new computer in both the Roaming folder and the Local folder the Thunderbird program still will not show me the old files. I don't need any of the thousands of emails in the old computer, just the Templates in one account. This should be easy. I should just copy the profile k41***** ect. and paste it into the "Profiles" (notice the pleural there) and then Thunderbird should work. But it does not.

Why do I continue to receive a message from Firefox after creating a New Profile?

Firefox This profile was last used with a newer version of this application. Please create a new profile. OK

A new profile PERSONAL #2 was created following the Steps to Create a New Firefox Profile.

What did I do wrong? how to correct, so that I stop receiving the error message?

My old laptop died, and just reinstalled TB on new laptop. I have the SSD with old profile, and added profile to the new Profiles folder. Thought it would be as simple as editing the Profile.ini to specify the old profile, but that hasn't worked. Need help.

im loged in to firefox and i want to change from 1 of my profiles to another one of my 3 profile but it wont let me choose on of the other profile it show them to me but cant pick one ?i have work to do and i cant get anythiing done because of this ?

Win 11, v.153.0 Firefox (default), v.153.0 T'bird.

Lately, when there's a link in an email and I click on the link, it takes me to a Firefox browser that's not my normal one - this new one doesn't have my settings, saved passwords, or home screen default, etc.

What happened and how can I fix it? Or must I wait for another update? (It just now updated to 153.0 and the problem still exists)

It is quite annoying.

Thanks.
