Hi there. I love Firefox, but I have an issue at the moment where I have one copy set up on my Mac, and it has two profiles. However, I'm running into regular problems where they're both open and they can't quit, or they crash, or they want updates, the other one, and then it has to be restarted and can't open web pages for stuff like that.

A little bit more about my setup. I have two admin accounts on my Mac and an applications folder with Firefox in it. Then each of my Mac accounts has a version of Firefox with a different profile.

I'm about to do a clean install of macOS with the two admin accounts. I want to install Firefox correctly this time. How do I have two entirely separate copies of Firefox running on my Mac in the two admin accounts? I just don't want their threads to be mixed or them to be updating each other or anything like that.

Absolutely love Firefox, but this has been quite a big issue for me and I'd love some advice here. Thank you.

Additional note, I followed the link below the first time I setup to create two profiles, but that didn't quite do what I wanted.

I have the latest version of Windows 11 installed. When I try to download Firefox 125 I get a popup window stating Firefox 125 cannot be downloaded on a computer with the operating system less than Windows 10. Is there a work around to remedy this problem?

If I try to import Mail Message in Outlook 2016, the progress will not proceed at 0%

Both Outlook and Thunderbird were running on 64bit

How to solve this?

Cox Communications recently discontinued its e-mail services but provided a simple, direct transfer path to Yahoo Mail. The transfer retained the '@cox.net' referent in the e-mail address -- e.g., 'myusername@cox.net' -- to make the transition to Yahoo Mail seamless for all correspondence. The new Yahoo Mail username also now includes the '@cox.net' referent -- e.g., the former 'myusername' under Cox is now 'myusername@cox.net' under Yahoo. The transfer was successful, and e-mail send & receive functions for all of my old Cox accounts now work on the Yahoo Mail servers -- but ONLY in Yahoo's webmail.

in order to get Thunderbird to recognize my existing accounts under the new Yahoo regime, I went to 'Set Up Another Account > Email' and entered the required information, as illustrated in the attached screenshots. (See attachments 01 & 02.) The Set Up procedure initially found the old Cox server settings, apparently from Mozilla's archived data for the account. I Then performed a manual configuration, and, as indicated in the attached screenshots, the Set Up procedure also successfully found the new Yahoo Mail servers. Success, right?

Wrong! When I restarted Thunderbird, the new Yahoo Mail server settings were in place, but the username had not been updated -- it lacked the '@cox.net' suffix. After manually amending the username and again restarting, the new server settings and amended username were in place, but connection to the Yahoo servers failed repeatedly. (See attachment 03.) A second round of the 'Set Up Another Account > Email' procedure revealed that the archival Mozilla data had not been updated -- it still pointed to the old cox.net settings -- and a second manual configuration led to the same results as the first: Thunderbird failed to connect to my account on the Yahoo Mail servers.

I then looked for a way to completely remove the existing account from Thunderbird, and then to create a new account from scratch for the existing account on Yahoo Mail. I consulted Thunderbird online support advice [ref. 'Close My Account - https://support.mozilla.org/en-US/questions/1395523 ]:

"If you created a mail account in Thunderbird for a particular email address to download emails from server then you can easily remove it ( Menu icon > Account Settings -- Select name of account in Left Pane -- Click on 'Account Actions' -- Select :'Remove Account'. -- Restart Thunderbird. ),"

However, I could find no 'Remove Account' selection anywhere in the version of Thunderbird that I am using (ver. 115.9.0 - 64-bit)!

Please explain what I must do:

   1. to make an existing Thunderbird account originally set up for an old '@cox.net' address hosted on Cox servers now connect to a new '@cox.net' address hosted on Yahoo Mail servers; 

or, alternatively,

   2. to remove all traces of an existing Thunderbird account originally set up for an old '@cox.net' address once hosted on Cox servers, and then to set up a new Thunderbird account for the same '@cox.net' address now hosted on Yahoo Mail servers.

I currently have a Outlook account and a Jagwireless email account. I am trying to move it to Thunderbird. I can now receive my Jagwireless Emails in Thunderbird but I can not send emails through Thunderbird. Any ideas how to fix this?

I'm trying to migrate Thunderbird from my old PC/Windows 10 to my brand-new PC/Windows 10, following the step-by-step instructions on https://support.mozilla.org/en-US/kb/moving-thunderbird-data-to-a-new-computer. I followed those instructions to the letter (multiple times) but can't get it to work. Are there more recent (and perhaps more complete) instructions to be found elsewhere? Does anyone else have the same?

I have made a copy of my old TB profile folder on a backup stick (it is titled 'Thunderbird', and inside that folder is a folder titled 'Profiles' that contains a number of folders including the most recent profile that I am still using with my old PC. The difficulty is getting this backed up profile info installed on my new 'destination' computer.

Any suggestions would be greatly appreciated.

Cox has tranferred my email accounts to Yahoo. I need to know how to connect back to Thunderbird. Had a discussion on your FB group with ANJE YELF.. She said to leave a message here and she would get back to me on how to do that. I have imap.

Moved to new country (UK) took TB data with me as instructed. Installed TB did put in email data. Uploaded TB data as per instructions. Opened TB and put in email password etc. All my current emails show up no problems and email account appears to work but none of the uploaded data appears even though it took 15 min to upload. It feels like it was uploaded to the 'wrong' place but I uploaded the data it to the TB folder as instructed. Any idea what I did wrong??

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.
