Hi, T/bird working fine upto Thurs night Feb 26th then yesterday morning I got pop up windows asking for login credentials. Nothing had changed. Tried logging in thru them put it errored: <<

               Something went wrong

We could not sign you in. Try again from a different device. >>

I can log into my Yahoo accounts using Firefox so passwords isn't the issue

I've read thru a number of threads on here and elsewhere but no solution so far. K9 is working on my Android phone and my wife's and her T/bird is working on her PC. Just checked versions, she is on 140.8 ESR and I'm on 148.0. Both running Win 11 Pro.

Tried changing from OAuth2 to Normal, pop window asking for password but that doesn't work

Seems to me to be an issue with Ver 148.0 as my wife's working

What am I missing?

I use Firefox as my desktop (and phone) browser. Recently my desktop cannot open my USBank Online banking service (my Android Firefox phone browser works fine). The USBank customer technical service agent tells me that their software does not recognize the Firefox browser - he says that AVG Secure, Microsoft Edge , and Google Chrome work fine). How do I rectify this without changing browsers? I've used Firefox for opver a decade without trouble. Help!

I received an email on 02/25/2026 that was a egift card from a local small business. The egift card was from with Square account. When I went back into my inbox the next day to use the egift card, the email was gone. I looked in all my folders and didn't see it anywhere. How can an email just disappear? When I contacted the small business, they said they can't honor the egift card without the 16 digit # on the egift card. I showed them the receipt for the purchase but it doesn't not show the 16 digit code for the ecard, only shows the purchase of a gift card. So how do I find this email with the egift card?

this was the email address from the purchase invoice. noreply@messaging.squareup.com

I don't recall the actual email address the egift card was from other than I saw it was from a Square account.

Hi,

Since installing the latest FF update (148) a few days ago, I have trouble replying to any topic on this site: https://www.4x4community.co.za/forum/. Prior to this update, there was no problem in replying or posting to the forum.

I do not have this problem on any of the other forums of which I am a member, only this one. I can log in and read posts with no problem, but I cannot reply to any post. I am also unable to start a new post on this particular forum (of which I am a Moderator). There is no flashing cursor when I wish to post, and I also cannot 'copy & paste' a reply either.

I have disabled Malware Bytes, Dark Reader and AdBlock plug-ins, this makes no difference.

If, however, I run FF in the "Troubleshoot" mode, I am able to to post replies to this forum. I have reinstalled FF v148 twice, the issue remains.

Testing the same forum with Opera browser I can access and reply to the forum above, even though with Opera I use the same plug-ins mentioned above turned on. It appears to thus be a FF permissions issue. I have cleared my Cookies and cache but this did not help.

Do you have any other suggestions? I am a FF user from day 1 all those years ago and have no desire to change to another browser.

Regards, Eric

It appears thousands of others have the same issue with NOTHING affecting the search bar handoff to the address bar (changing true/false in about:config does NOTHING, v148.xx). Why not just do away with any search bar and do everything from the address bar? That way enough will be annoyed they'll find an operational browser. Like too many "upgrades," this one went seriously backwards.

Firefox memorizes userIDs and I do not see an option to stop it from doing so. Is there an option?

Keep in mind that passwords are not limited to the password entry. Every entry in a sign-in process is an opportunity for a password. For example, the answer to "What street did you grow up on?" could be "Beatlejoice". Similarly, the answer to "What was your mother's middle name?" could be "Aardvark". Nonsensical answers to security questions are more secure than truthful answers.

Again, in the interest of security, is there an option to stop firefox from remembering so much?

I've recently set up Thunderbird on Linux Mint 22.2 and was unable to sign into Yahoo so I tried to sign in with Firefox instead and had the same errors :-

   Something went wrong
   We could not sign you in. Try again from a different device.

OR

   We couldn’t sign you in
   Change your browser settings to continue. Try the following:
   Turn off ad blockers
   Enable JavaScript

If you still can’t sign in, try a different device.

I can sign in with Chrome without any problems on the same workstation. Firefox version :- 147.0.4 (64-bit)

   Only Extension is Privacy Badger, but this is disabled for Yahoo.com

Thunderbird version :- 148.0 (64-bit)

   No extensions - as installed from Thunderbird download site

I'm not having any issues signing into any other websites / email accounts (Google, Hotmail).

I notice on the support website :- https://support.mozilla.org/en-US/kb/thunderbird-and-yahoo it says "Starting with version 148, Thunderbird is switching to a more secure authorization protocol PKCE for Yahoo" BUT this isn't offered in the list of Authentication methods, has PKCE been delayed? Currently using OAuth2 for Thunderbird

these shortcuts appear on my firefox home page are so annoying here is my setting , i toggle off all shortcuts related to history or sponsored shortcuts but they still pop up each time , i want to disable this feature i need only my selected shortcuts appear on home page what can i do ?

I know that there is already default containers built-in without the need of the extension. But there's no way to open tabs in containers when we click a link, only when it's typed in. There's an option in settings that allow to pick a container when a new tab is opened, but that's it. It would also be great to move the Mozilla VPN and integration and sync function from the extension to the settings page for easier access.

I have 5 email accounts stored in drive I: and 3 in drive C:, with multiple profiles (in I:(...)\Roaming\Thunderbird and \Local\Thunderbird AND the same in C:). (Windows 10). I need to move to a new PC (Windows 11), where drives are named C: and D:. I tried to use the Import/export function, but the accounts previously in I: don't appear (only the basic account shows, no inbox/sent, etc. and no data). I manually changed one of them to C: and then import again only the data. That was not possible for all the accounts and many emails (90%) are missing, also from the account were it "worked". I can find some emails in folders at the bottom of the account list, but many emails are yet missing, and received/sent not clearly defined. NB: on Windows 10 I have the latest esr version, on Windows 11 the latest NOT esr version.

So I tried to manually transfer the archives, but when copying from \Local\Thunderbird to an USB for the transfer, many files (more then 40k) went missing due to errors of copying.

What can I try?

The calendar has a way for you to see all calendar events. Is there anyway to view all calendar tasks? My goal is to clean up the calendar by removing old tasks.

Can get(POP3), but can not send emails to a newly created personal outlook.com account.

the following error occurs when trying to send mail: Unable to authenticate to Outgoing server (SMTP) . Please check the password and verify the 'Authentication method' in 'Account Settings | Outgoing server (SMTP)

all my setting are correct per thunderbird and microsoft:

  (smtp-mail.outlook.com, port 587,  STARTTLS, OAUTH2, xxxxx@outlook.com)

thunderbird error log file contains the following: . . . mailnews.smtp: S: 535 5.7.139 Authentication unsuccessful, SmtpClientAuthentication is disabled for the Mailbox.

Based on my understanding its seems thunderbird is using SMTP AUTH instead of OAUTH2 as required for newer personal outlook.com accounts. Is my assessment correct? If so, is there a fix?

One of my two outlook email accounts no longer appears in Thunderbird, which says it is authenticated but not connected. This happened suddenly. I can still get the messages by going onto outlook.com. How do I get it back on Thunderbird?

Although Firefox for Android has support for PWA websites in general,I see that it doesn't detect all pwa websites and creates a simple shortcut instead! For example go to mytuner-radio.com and try to install it as a Pwa, it just creates a shortcut!

If you try this on other browsers like Vivaldi for Android, it installs it as an app, without the need to open the whole browser alongside all the tabs,every time you tap on its icon !

Please fix this and make all sites that support pwa detectable !
