Over the last week I have been experiencing issues that prevent me from using Thunderbird on my computer. It had been working for a few weeks prior, with emails sending without issue. Without any apparent cause, and with the correct credentials set in my account settings, emails are no longer sending. They continue to be received with no issue, and I can move emails into folders etc.., which I immediately see reflected in Webmail. I get the attached error, every time I try to send an email, no matter which address I am trying to contact. I can log in to my account with the same credentials on different software on the same computer, and I have no issues with sending emails from that software, so I can't see how this would be an issue with my computer. I have tried removing the account, and adding it again. The credentials are accepted, but the issue persists. The email also works without any issues via Webmail. I have contacted the hosting company for support, but they have confirmed that this is an issue with Thunderbird. Please can somebody help?

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

I'm reading this> https://support.mozilla.org/en-US/kb/thunderbird-export#thunderbird:linux:tb148 Looks great but all of my messages sit on IMAP servers and I don´t need a backup of those. I _do_ need a backup of settings, passwords, pgp keys, to move to another workstation. It is unclear what exactly is exported.

I deleted a profile not knowing it would delete everything I had. How can I undo it? I didn't want Firefox Profiles, it was forced. I deleted it, and everything just got deleted. Can someone please help revert this? Thanks.

I want to access an Outlook.com email. It has 2-step verification. It also says I may be missing a domain name before the email. Not sure what that is. DomainName/myemailname@outlook.com.

bold text how to stop address bar search. its very wrong you have a fake search bar in the screen i want to search from a search bar not the address bar

When opening a new window, I get this https://hp-search.com/?path=firefox/newtab&u=7548f4ddec01b2d6&subid=11119&channel=default

I am not sure what to do first. I already paid for the VPN subscription. I reinstalled Mozzilla VPN but have not yet put the sudo lines in that are listed in the help on Firefox. Can you send me an email with instructions and any special sudo lines I need to intall so I do not get charged a second time. I heve the recovery code. I am new to Mint. Windows 11 started knocking out my hardware with power surges. Had to come from the operating system itself since the machine is hooked to a power backup that smoothes the current out. Converted everything to Linux. Like it. Life can be cruel... LOL Thanks so much for the effort. [edited] landline, but best bet is email. [edited phone# and email from community support forum]

I need help recovering my phones my settings my photos on my accounts and passwords have been changed on two devices by a person that was not supposed to be using any of my accounts including my Mozilla

I started using Claude in the side panel instead of a dedicated tab, but there is something noise about it: every time I click to open the side panel the chat starts from scratch. Getting a clean slate is nice, but it takes too much time loading. So I would like to not unload the content of the panel when I close it, just hide it, so when I click to open is already loaded. There is a way to do that?

Hello,

Can you please help with the following scenario.

Both, a Firefox sync master account and Firefox Relay extension are active when running the browser.

So, is it possible to change the master email addresses of both features (+ secondary email) ? I would like to use a new email address for authenticating in both features of Mozilla, but do not want to set up new accounts.

How can I do that in Firefox Sync and Relay?

Thanks for your support.

I recently updated to 147.0.1, and now it seems I can no longer access word/excel/powerpoint files for online editing. I have already tried clearing cookies, disabling adblockers, disabling tracking protection, running in a private window, all the way down to completely reinstalling Firefox 147 fresh. This has persisted for roughly a week, so it does not seem to be an issue with my own network connection, nor with Microsoft's services, nor my files specifically since I can edit the files online from my PC at work. The error message specifically reads:

We can't connect to the server at usc-excel.officeapps.live.com (or usc-word-edit.officeapps.live.com or usc-powerpoint.officeapps.live.com, respectively).

I could previously access these files to edit when I was still on Firefox 146, so I'm guessing it's something going on with 147. Has anyone encountered similar issues with Web Office apps, and perhaps found a resolution?
