All the settings for both incoming and outgoing servers are correct. I can receive emails but cannot send any from Tbird. I keep getting an error message that says "Login to server smtp.office365.com with username failed". Additionally, the SEND folder is not visible in my email folders. I have confirmed that the outgoing server information in the account settings is correct, please see the screen shots.

Server Name - smtp.office365.com Port-587 Connection Security- STARTTLS Authentication method - OAUTH2 Username: my full email ID

Please can you help how can I resolve this error, thanks.

Hello, yesterday (Friday) I downloaded the program Pure Web Browser, which was one of the advertisement on Firefox website when I opened it. Later, I discovered that Pure Browser was blocking many things, because I could not perform functions on some websites, such as getting my email because it blocked me signing in. This happened with several sites.

Could you please tell me how to delete Pure Web Browser, as it is causing problems with the PC. I have tried, and had no success.

Thanks for your help.

When I clicked troubleshooting mode FF unexpectedly closed my Private browsing session and all the tabs. How do I reopen them?

I did not expect FF to close on me like that. I thought that as I was in a private browsing session FF would have warned me that it was about to close had it been necessary.

I'm guessing that my open tabs have been lost permanently because you didn't warn me and that all that time I spent is now wasted.

Life is really simple except that other people make it problematic.

Firefox is my default browser however if find that it does demand a significant amount of RAM whilst running for example today it is running 800 Mb with only 5 tabs open but earlier it was using 1200 Mb. This demand is slowing down my computer as other programmes are being impacted. Is there any way of restricting or limiting the amount of RAM being used by Firefox. Currently it is normally at the top of programmes using the greatest amount of RAM.

I had to reset my primary password. Now the new password is not being accepted. And I keep getting a pop-up asking for the password. What can I do to have my password accepted?

I already tried to un-check "use primary password" in settings but cannot accomplish that with a password that is rejected.

My wife and I share a laptop. We both use Thunderbird for e-mails. Mine works fine. My wife has just started getting problems opening Thunderbird from the Task Bar. On clicking icon, message comes up 'Thunderbird already open. Close Thunderbird' How do we fix this problem, she can't get into Thunderbird at the moment.

in thunderbird I have 2 email accounts. I want to stop the outlook account from automatically redirecting all emails to my other account. I set this up a long time ago and I don't remember how it was done.

As per the subject, I can no longer restore all of my settings after this last update. I guess it's time to explore other options. Mozilla is nowhere as good as it used to be. That's progress. Low-paid interns and shoddy support help to influence.

Hi support team,

I was using Mozilla Firefox on my Samsung Galaxy s20+ without any issues. I have transferred all data from my old one to new one, Samsung Galaxy S24 after this migration Mozilla Firefox crashes, when I was forwarded from an app.

Standard browser: Mozilla Firefox I have already reinstalled the Mozilla. This action works properly with other browsers.

Kind regards Mustafa

I need proper entries for Incoming and Outgoing servings (POP3). My existing account username is

• • • • • • • @gt.rr.com

Please direct all replies to tenxfox@gmail.com since "gt.rr.com" isn't working. (duh)

Thanks in advance, Chris

How does Message Filter decide where to move an email if there are two recipients have both have a filter? I thought it might be the first one on the TO line but it is not. I'm always searching for emails because they end up in the wrong folder.
