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.

UNABLE TO DELETE MESSAGES FROM MY INBOX

I have a problem with being unable to delete messages from my in box.

I have searched the online support and found a couple of articles going back to 2020:

https://support.mozilla.org/en-US/questions/1292956

and

https://support.mozilla.org/en-US/questions/1293317

but they seem to relate to an older version, as mine is 115.4.3 (64 bit).

Having taken a backup first, I’ve followed all the instructions including deleting the Trash folders and forcing an index repair without any success.

The problem doesn’t occur on every message and I seem to be able to delete the odd one but at present I have almost 1,000 messages in my inbox awaiting deletion.

I’m using Windows 10 Home, version 22H2, a POP3 account and regularly compact all folders.

The second of the above articles asked for an image of my ‘pop account name’ folder, which is attached.

I hope someone can help me please.

Regards and TIA

When I try to play a video on Firefox desktop, it takes it a long time to load. Once it has loaded, whenever I pause it for more than a few seconds, or if I try to skip around the video (either by clicking around in the loaded section of the progress bar or using +/- seconds buttons), the video begins buffering again before the video resumes. This makes it extremely difficult and frustrating to watch anything that requires me to pause, rewind, or fast forward. I've noticed this issue affect multiple video viewing sites, such as YouTube, Vimeo, and Netflix. My roommate also uses Firefox, but doesn't have this issue, so I know it's not a problem with my internet. I thought it might be a problem with my computer, but I tried to replicate the issue in Chrome and everything worked fine there. The issue has persisted almost a week. I have:

• Rebooted my computer several times
• Deleted my history/cache
• Disabled my extensions
• Turned off Java scripts in firefox (this disabled my ability to load sites like YouTube completely, so I turned it back on)
• Updated my computer
• Updated my graphics drivers
• Refreshed firefox
• Uninstalled and reinstalled firefox (and rebooted my computer)
• Uninstalled and reinstalled firefox AND deleted all the data it stored on my computer (and rebooted my computer)

I am currently using version 123.0.1 of Firefox. My OS is Windows 10 22H2.

Hello,

This is my very first post to a support community so please excuse me for any rookie mistakes and oversights.

T.B. 115.8.0 (64-bit) Windows 10 - IMAP settings with multiple domains and multiple accounts on each.

Problem/Issue: Most searches return the expected results, but in certain cases, and seems to affect mostly the sub directories in Local Folder (have not been able to replicate problems in strings found elsewhere).

Things I have already done: - Rebooted PC - Compacted the folder where the email resides - Repaired such folder - Confirmed that Global search is clicked for such folder - Opened the email to confirm that it does open and is valid (Remember that it's in Local folders so already downloaded)

E.g. Global search string "Re: New Project 25-301-623 needed into Swahili - word count 321" (which does exists in Local Folders) does not produce any results but (Deleted first character of the string) "e: New Project 25-301-623 needed into Swahili - word count 321" produced results for "New Project 25-301-623 needed into Swahili - word count 321" without the results for "Re:...". Additionally, no filters are displayed such as Location, People, etc. (Running the same search within the folder where it resides works fine.) Cutting down the string to only "Re: New Project 25-301-623" still does not find any results. Global search for string "Payable Summary for: August 2022", which resides in the same folder tested is found but no filter data available for Location, People, etc. However a search for "Project delivery for Job: 25-258-813" again residing in the same folder is found with Location, Account and People. I've tested same approach and tests on different folders to rule out Folder specific problems and behavior is the same problem.

Another example that might help in figuring things out. I tested a string of an email subject from an amazon order, which are long in nature do to # dashes, long numbers, etc. Performed a global search and the email was found but no Filters shown. Did the same search removing the end of the string "has shipped" and the email was found once again but with all Filters showing.

I hope I have been thorough enough. If any additional information is needed please let me know.

Thanks to all.

Dear Sir or Madam,

I have been having problems with Firefox on my Desktop-PC for about a week now: I am almost always shown another tab with an error message (an new tab with allways the same content) in addition to the website that is regularly called up and also works:

Tab-Headline: Seiten-Ladefehler Fehler: Verbindung fehlgeschlagen

Beim Verbinden mit 0.0.0.1 trat ein Fehler auf.

   Die Website könnte vorübergehend nicht erreichbar sein, versuchen Sie es bitte später nochmals.
   Wenn Sie auch keine andere Website aufrufen können, überprüfen Sie bitte die Netzwerk-/Internetverbindung.
   Wenn Ihr Computer oder Netzwerk von einer Firewall oder einem Proxy geschützt wird, stellen Sie bitte sicher, dass Firefox auf das Internet zugreifen darf.

It doesn't matter which regular website I call up - it also happens when I call up the Mozilla Firefox page.

It is as if my website call is executed twice: once normally and everything is displayed correctly. And once as an extra tab with an alleged page loading error where the connection has failed.

How can I prevent these additional tabs with the error message from constantly popping up and being displayed? I have not made any other settings and Firefox has always worked perfectly so far. It doesn't happen with Google Chrome, for example - so it's not my PC.

Can you help me?

Kind regards Daniela Bohle

Hello, I have migrated my thunderbird onto a new windows system but I now get not automatic download of messages, the only messages I might get is if I close down Thunderbird and reopen. Get messages does not do anything - not even sure its attempting to communicate with server .

Is there anything I can do or change ? I have literally spent almost trying various things and I am the point of giving up and trying a completely different email client. There should be a seamless migration method but it appears there is not.

I am running Firefox 121.0.1, which is currently up to date, on a slightly older MacBook, which has the latest MacOS it can get: macOS 11.6.8. As the title states, YouTube is almost unwatchable on my machine. The video will pause frequently while audio continues, motion is not very smooth, which is especially noticeable watching sports, etc. I cleared cookies and cache, I have run in Troubleshoot mode as well as tried flipping some switches in about:config that I've seen in YouTube videos and forum posts about similar issues, but nothing has solved this issue.

YouTube in Google Chrome works fine, and I've been watching HD YouTube on this laptop with it for years without any issues, so I doubt it has anything to do with machine specs like RAM, CPU, etc.

I was hoping to make Firefox my new browser and start supporting browsers that aren't chromium based since Google Chrome is going too far with respect to privacy and the freedom to use the add-ons I like (e.g. adblockers like ublock origin), but so far I have not been enjoying Firefox for YouTube. Any help would be greatly appreciated.

Hi I have a problem with the configuration of my Firefox. (I hope it is not something more serious like a malware or a security break)

Firefox version 124.0 (64bit) Os: Windows 10 Pro (64bit) 10.0.19045 Build 19045

Step to reproduce

1. 1. I go to: https://wwws.tesoro.es/index.aspx (website of the Spanish gov)
2. 2. I click on the link: Cl@ve in the center of the page (that should bring me to https://pasarela.clave.gob.es/Proxy2/ServiceProvider)
3. 3. I receive an error page "Did Not Connect: Potential Security Issue" "SEC_ERROR_UNKNOWN_ISSUER" (see the attached screenshot)

Things I tried

• I followed the same steps on Chrome on the same machine

The website works

• I followed the same steps on the same Firefox in Incognito mode on the same machine

The website DOESN'T work

• I followed the same steps on a completely new Firefox profile on the same machine

The website DOESN'T work

• I followed the same steps on Firefox on a different machine (same Firefox version, windows 11)

The website works

Firefox is my default browser, but it does not allow me to log in to specific websites. For example, ihg.com, when I click the sign in button nothing happens, I just have a little note at the bottom left "javascript:void(0);" Another example, dutchcrafters.com , when I click Log in with Gmail, nothing happens.

I have tried removing all the content blocking extensions (privacy badgers, ublock origin, etc.), did not fix it. I have tried a firefox refresh, did not fix it. I have tried uninstalling and reinstalling firefox with several device restarts, did not fix it.

I know this must be a firefox specific problem because microsoft edge work perfectly for both of these examples. Any other suggestions to fix this firefox issue?

I have had very few notices about Thunderbird upgrades. My records show Setup numbers: 3.0.exe, 8.0.exe, 52.4.0.exe, 52.9.1.exe, 78.12.0.exe, and then 115.5.2.exe. My address book made it through all but the last upgrade. No notice that I should save a copy of my address book ever showed up in any correspondence. I tried reinstalling an old upgrade but the upgrade always wants to update the installation. I did try to reinstall 52.9.1, but the next screen wanted my name and password. It would not accept any name and password that I could remember. So I tried searching for them at Xfinity and Comcast to no result. I did not try my Firefox password because it didn't seem appropriate. Incidentally, my records show 135 upgrades for Firefox for the same length of time as the upgrades for Thunderbird. My fear is that my address book is unrecoverable. I chose Thunderbird because I ofigured none of it would need backup if it became necessary to reinstall Windows 10. Which happened last year. I did not expect Mozilla to change Thunderbird so drastically that I couldn't get every thing back. Sorry but I'm a senior citizen and not computer literate. If I have to try to recreate my address book I may as well use Microsoft's Outlook as it looks somewhat simpler than Thunderbird - which I doubt.

Hello. I was searching my Inbox for e-mails I knew I had, but they weren't showing up! After doing a general search, I found the e-mails in the search results. Then, I clicked "open in conversation" and they were all there and labeled with "Inbox" or "Sent" folder, respectively. So I right-clicked and selected, "open in containing folder", but it didn't work! The "containing folder" opened [i.e., the Inbox], but didn't show the e-mail! So then I searched manually by scrolling in the Inbox to the date of the "hidden" e-mail -- yet it wasn't there!

(In other words, when I did "open in conversation" from the search results, it showed the conversation, but I can't actually see the e-mails in their containing folder!) Besides for this problem, but I think there are a lot of other e-mails that are "hiding" in this way as well. What should I do?

Thanks for any help you can provide!

Sincerely, Jonathan Rosenberg

I have a personal family domain, with email service - my provider supplies me with a number of pop3/smtp addresses.

I have a Thunderbird a/c setup on a desktop running Linux Mint, thgunderbird version 115.5.0 (64-bit) SUPERNOVA using one of the pop3/smtp addresses - husbandATmydomain.me.uk and I receive emails from another of the domain's pop3/smtp addresses, sent by my wife from a Windows 10 laptop using Thunderbird, under the address wifeATmydomain.me.uk

Her Thunderbird a/c is correctly set up in her Thunderbird, to use the smtp server for her email address, wifeATmydomain.me.uk. There are no other addresses or identities set up on her thunderbird account. My thunderbird a/c is correctly set up to use the smtp server for husbandATmydomain.me.uk and has several other pop3/smtp addresses able to send addresses using their own smtp servers.

In MY Thunderbird address book my wife's address is given as wifeATmydomain.me.uk, with the display name "wifefirstname surname".

When I receive an email sent by my wife, to me, it appears in my Inbox with the Correspondents column showing MY name not hers. This means I am constantly missing emails from her. because her name is not visible in Correspondents column, but mine is there instead.

The Reply To: and From: addresses are correctly given as wifeATmydomain.me.uk when I examine the receive email details. It is only displayed with MY NAME, in the Correspondents column in the Message list header pane, using Classic View. Everything about her emails displays correctly in Message View, using Full Headers display.

The only thing I could find in research was to make sure her a/c was using the correct smtp server. It is.

How can I fix this please?

I can login from other web browsers, but not Firefox. What's going on?

When I try to login as I have always dine in the past, this is what comes up: https://outlook.live.com/mail/0/

But then absolutely nothing happens. Please advise.

I really like this app. I always use it on desktop also but after a few last updates I noticed that battery usage of this app increased a lot and the percentage is very high. 1 hour screen time on youtube was 4% battery usage but on the firefox side it was 17 min / 11% battery usage. If you fix this It will be perfect for me. Here are the screenshots with different days. And I'm using sync feature and ublock addon. I always close the opened apps and I use deep sleep feature on my samsung device. And I forced to close the app. For now I stop using firefox for test purposes.

Firefox stop from 2 days ago read Google Recaptcha, from nothing.., Dev version to.. I have the last 126.0b8 and both not working, I try disable Tracking Protection and still, clean everything... spinning forever...

I try my Firefox at mobile, that works. I need Firefox working on this. Cant use Chrome...

Help!

I can open the Chase bank site, but cannot log into my account. I can log into my Chase account using Edge. This may have happened after the most recent update to Firefox. Any ideas how to fix this?

All of our "read" emails, --from all of our accounts -- have suddenly disappeared. All of the folders and subfolders are still present. We still get new email, but as soon as we read it, it's gone. We have had these same email accounts for years and have not made any changes. In Account Settings --> Synchronization & Storage --> "don't delete any messages" is checked. "Read" messages are still on our server.

So, 1) Why did this happen? 2) Is there any way we can get our messages back in Thunderbird?

For the past few days when I have tried to log into a few websites which use TLS/SSL I have gotten PR_CONNECT_RESET_ERROR. Please see the attached screenshot for more details. This issue was observed ever since I updated to Firefox version 124.x. Prior to that the websites were working fine.

When I try to access the same websites and try to log into them using Microsoft Edge, I do not face a similar issue. They work fine.

I have cleared the browser cache, restarted firefox, and then tried. Still faced the same issue. I have cleared the DNS cache of Firefox browser (about:networking#dns) and then tried. Still faced the same issue. I have opened Firefox in Safe mode (Menu > Help > Troubleshooting mode) and still faced the same issue.

Can someone please help me in fixing the issue? I would like to refrain from using MS Edge or chrome browser.
