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

Reference #18.acf7d517.1771548295.4f66cee0

https://errors.edgesuite.net/18.acf7d517.1771548295.4f66cee0 is what I get when going to https:\goddady.com as of today. Running on Windows7 (no, I won't upgrade). Tried a variety of changes. But Chrome works fine. Any suggestions?

When a message is removed from a folder via that folders' Retention Policy, is the message permanently deleted or does that message go to Trash? I use Thunderbird with Gmail via POP. Thank you.

Since the latest Firefox latest update yesterday (02/24/2026), each time I try to open a new tab in Firefox it crashes. I get a "gah, your tab has crashed" message but when I hit the "restore" link nothing happens. How do I fix this at my end? Thank you.

I am getting repeated pop up "alerts" from Firefox, McAfee and others about Trojan Horse and other viruses. I did not click on the links offered. How do I stop them from coming?

I set the about:config settings when I got the new computer early last year. It's been working fine. Suddenly, searches are popping up again to the urlbar.

browser.newtabpage.activity-stream.improvesearch.handoffToAwesomebar is still set to false. Keyword.enabled is still set to false.

I see a couple of site references to browser.fixup.alternate.enabled, but it doesn't exist.

How do I get FF back to proper search in the search bar?

I sent another help request on this subject but that too seems to have gone AWOL so I am trying again.

My passwords are being randomly wiped from my PC yet again but this time, although they are still on my Google Pixel 7 phone, Sync is not working for passwords. Strangely however, tabs are being synced.

I have tried every suggestion that I have found but syncing is just not happening.

To re-cap:- Passwords are not being synced from phone to PC Tabs are being synced between phone and PC.

Any suggestions?

Moderator note: This question has been edited to add a link to the previous question.

I want to create an email contact that will send to two separate addresses every time I am on v 148.0, I see the instructions for adding a mailing list but the instructions found so far do not appear valid for this version. File>New>Mailing List

I am using a condav address book, perhaps this where the problem originates

Can I create the contact in the condav book directly and have it show up and work in TBird?

I have created a mailing list in the "collected addresses" address book as a workaround

Will try the direct entry to condav to test that method

So, updated from 147.x to 148.0 this morning 9Win 11 Pro), and didn't take me long to realize that the upgrade nukes Google calendaring using Provider. With 148, if I look at the calendar, 100% of the entires are 'missing'.

If I (i) unsubscribe from the calendars, (ii) uninstall Google Provider, (iii) re0install Provider and re-authenticate, (iv) re-subscribe, then calendar entries are shown.

But...if I turn off TB, and turn it back on again, calendar entries disappear.

Note this is only an issue with 148.0. On my other machines (which largely run 140.x), not a problem.

I want to be able to permanently delete (equivalent of Shift-Delete) emails using a filter. Currently I can't do that. Selecting the delete option in a filter just moves the email to the trash. That means I have to handle the email twice in order to get rid of it.

Other email clients offer this feature. Why doesn't Thunderbird.

Computer PC-A died. Had access to data

Recovered PC-A:CalA: ... users .... roaming ... <profilename> calfiles

Installed TBird on another machine (PC-B) Copied the three sqlite files from backup to same location on that other machine. Deleted WAL file. Restarted. CalA does not appear' on PC-B.

is the <ProfileName> in the sqlite files?

What to do?

Just a couple hours ago I tried to attach a photo from my Samsung phone. I was successful doing so earlier today. Now I get this message and have no idea what to do? "C:\Users\Owner\Desktop\Jack.jpg could not be opened, because the associated helper application does not exist. Change the association in your preferences." Can you help?

If I sent emails via my iPhone or iPad, they show immediately in the Sent folder on iCloud.com (visible in a web browser). But ones I am sending now on my Mac (Tahoe 26.3, ARM) using Thunderbird don't show in the Sent folder.

I really have no idea how long this has been the case - I just tripped on it as I was trying to verify that an email had in fact been sent from my Mac. (I'm a senior - maybe they never got saved and I just never noticed).

I sent a number of emails to myself - they arrived but don't show in the Sent folder.

Maybe I need to set some value in the email header to have it saved? Or something there is suppressing saving? Or they are not suppose to appear there?

Thanks for any insight. David

Suddenly I cannot search from the search bar. It defaults to the address bar. why "fix" something that was not broken. Being forced to use the address bar is frustrating. If you go directly to the address bar, it tells you it cannot find that site.

How to fix the problem, is with my Skymesh.com.au This has been happening yesterday & today, My thoughts are Microsoft has done something Help please embreys@protonmail.com is another account my normal is embreys@skymesh.com.au but the mail comes 48hrs later.

The breach source was Canadian Tire, but I've never bought anything from them online. Why would my credit card, email , credit card and phone number be compromised?

The Braille Institute has developed fonts that are 'hyperlegible'. How do i make "Atkinson Hyperlegible Next" the default font for headings, toolbars, message list, etc?

Since the last update I’m able to login to my banking websites but there are certain functions when I’m not able to do. Specifically I am unable to open the particular page that allows me to view my previous bank statements and download them. I get a crash problem each time. I bank with Navy Federal credit Union. And One AZ credit union I was able to access these pages using Google Chrome. I am submitting this through my phone browser because using the PC browser will not open your feedback pages. I get a page crash with that also.

For many years I have been using my Windows 10 with Thunderbird and a cell phone. Something happened when I updated Thunderbird on my laptop three few weeks ago. No emails go to my S23. Can someone please help me? I downloaded current Thunderbird version to my laptop. Problem might be being asked by Micros for my account email and password going back many years and I have not clue what it is. There is a chance Microsoft as blocked me from changing though I have no clue how to restart with them. April will be 3 years since I purchased my S23 and everything was good prior to me changing my Thunderbird password. Please help me.
