I've been using Thunderbird for a very long time now but I've never experienced this kind of problem: I have few outlook.com accounts set up and looks like I can't send emails from outlook.com using Thunderbird. To send a new email or respond to my emails I have to manually log in to my outlook website account or use my phone (Android). Every time I try to send or respond to email the Thunderbird I get these messages (included in the attachments): no connection to the server or it keeps asking me to put my password even though passwords has not changed. There seem to be no problem with receiving emails.

I am writing to let the community know that, at least in my case, the guidance from TB 1/2024 KB article on Qauth2, [and linked Microsoft article], didn't solve the odd password behavior that began around January, 2024, between TB and my Microsoft hotmail account--which had worked perfectly with TB for maybe 10 years?

Beginning in January I typically received an error message that SMTP server login failed; please enter password. But after fixing that as per the KB article (first trying to maintain normal password, then when that wouldn't solve it, turning on 2FA, switching to Qauth2 with cookies enabled), it turned out for me that with Qauth2 and 2FA, I could send mail okay but then the Outlook.IMAP server would not connect so receiving emails stopped. Several times after this failure I tried switching back to normal password AND turn OFF 2fa in order to get Outlook.IMAP to reeive email...but then SMTP would keep requesting passwords, and every day or two i'd get a repeated request to reenter the Imap server password for receivfing also.

The only stable fix I found after weeks of livign with this and debating abandonment of TB came when I turned 2FA back on, requested an app password from my Microsoft Account, changed TB Server settings back to Normal password for SMTP and Outlook.Imap, and then entered the App password when prompted by TB for to eonnect with server for receiving and sending.

This has worked fine and apparently been stable, without new reqauests to me for passwords, for 2 days, whereas all other fixes in past couple months have not lasted longer than a day or less before TB requests again that I enter a password to connect with my hotmail account. (All through this my gmail connection via TB ahas remained flawless, thought I did get a request for a gmail app password, which I obtained and entered--just once and all has since been fine).

I don't know why several careful step by step attempts to do everything in Mozilla's Thunderbird KB and Microsoft articles suggested didn't work--for a residential Microsoft account, whether I tried to follow guideance for those experiencing SMTP problem only, or the Imap server connection generally.

My only guess about why my Win 10 desktop installation is different? I have Outlook for Android running on two or 3 different Android devices also, perhaps that complicated things?  I also used to have a mirrored account (in other words, name@hotmail.com is my main account, but I also had a 2nd "nickename" acct with the same name, set up as name@outlook. com.  

(But I removed that nicknamed acct in case it was causing any of my authentication problems; made no difference. )

is there any way i can roll back the most recent firefox update? i updated firefox on june 12th and ever since than, i can not use firefox or open any tabs due to it continuously crashing over and over with no recovery. it is so bad that i had to go to microsoft edge just to report this problem, because i can not get firefox to open anything beyong my homepage without crashing the tabs. please email me at gnralee01@yahoo.com this is infuriating and i have to now use microsoft edge for my browsing because i can not use firefox until you fix this. i have uninstalled and reinstalled firefox 3 seperate times and i still get the same results. firefox worked great prior to the june 12th update.

I am running macOS 10.15.7 and Firefox won't upgrade past ESR v. 115 to the "regular" version 127.

Alternately, downloading the Firefox v. 127 installer and running won't update ESR v. 115 nor will it import bookmarks or data from the previous version ESR 115. Firefox v. 127 installs and starts as if I am a new user without any update or import option so that all previous settings, passwords, and data from ESR v. 115 are lost.

Is there a work-around for the upgrade to keep continuity, settings, bookmarks, and data when migrating to v. 127? Thanks!

My Firefox is the most recent version 126. I am having trouble with pop-ups being blocked. I have added the website to the pop-up exception list. When I go to the site, it shows me the little icon showing I have added exceptions for this site. However; the pop-up still gets blocked.

The site is: https://www.foxit.com/ I try clicking the Log In drop down then Foxit Account. Before this would pop-up the log in screen for the site but since version 125, it does not. I just updated to version 126 to see if that resolved it before creating this post but it didn't. Thus I am here trying to get help.

Hello! A year or two ago I ran into a problem. While Firefox is checking for an update, it does not load any sites. I have to wait about 5 minutes each time before I can start using the browser. It is incredibly annoying. Has anyone encountered this kind of problem?

I went to this site, no worries, nothing there but asks you to click...which you should not do. It says to copy the fix and paste it into the windows shell... sounds obvious, it's a scam. Except, this is a major funding company.

So the question is, is this legit from firefox? Or is that what? Go to myforwardsavings.com and you'll see what i mean. Or, see image i have included.

Hopefully someone up the chain in firefox can let me know. As i intend to report them if this is nefarious. Thank you.

A few months ago my bank statement from wells fargo stopped showing the information. All I have are the heading and lines... no information. I was told by Wells Fargo it is a security glitch in the Firefox preferences. I was not able to find what they were referring to so I am contacting you for help. Instructions on where to find this would be greatly appreciately. It was something about unclicking encrypted security and that bothers me somewhat.

I was using foxfilter extension on spin browser in android and spin uses Firefox at it's core . The extension used to work well until some point in the past and suddenly it stopped working . I reached out to foxfilter support and they told Firefox stopped supporting some extensions on Android and thus the issue . Is there anyway you could start supporting foxfilter on firefox Android or can i use an olderversion of firefox on Android to get foxfilter working . If so could you guide me how to get that version installed ?

Hello! Hope you reader are doing well. Sometimes, I'll even dare say most of the time, when I browse YouTube on Firefox and enter a video - it loads fine (currently 😢) but the thing that says what the browser is doing right now - I don't really know how it's called, sorry - keeps showing, and the only way for me to remove it when it's stuck is to refresh the page. It is a small yet annoying problem, and been persistent through Firefox's updates. Thanks for reading and helping to make Firefox the best!

I stored a password for particular web site. When I reset the password and stored it again. but your site does not revise it. then i try to remove it but you offer to passwords for all websites. THIS PREVENT ME TO STORE PASSWORDS IN THE FUTURE.

Hello,

My boss, (small family business) insists on using Thunderbird for the business. He sends and receives hundreds of emails every day. Often times has 20+ email tabs open at the same time. It's become such a problem that I have purchase larger SSD drive because he was always running out of storage space on his PC. His Thunderbird file is currently over 12 gig.

The main issue is: He will have several emails open and will start to reply to a customer. When he hits reply, the body of the email references data from an really OLD previous email that was either archived or deleted. Most of the time these are emails that were previously deleted. Then he goes back to his Inbox to try to find the original message and it cannot be found and is missing. He then finds the original email on his iPhone Inbox (Same Email Account - IMAPED to his phone) then forwards it to himself, in order to obtain the original contents of the message again. Sometimes the reply box has data from multiple old emails! It's hard to explain.

This goes on and on and he's driving me nuts, as I'm the local "Mr. IT Fix it." for the company. Although, I have no formal degree or training in such things. My background is in Accounting. LOL

From reading other forums, this appears to be either an IMAP Indexing or Email Deletion Retention policy issue? But it's just really beyond me!

Both myself and a family friend who actually has IT support exp. have told him to stop using Thunderbird for Enterprise use, and migrate to a more appropriate application. But he doesn't want to have to learn anything new or complicated.

Any thoughts, suggestions, other places where I can find a possible solution?

One other thought: This issue does goes go away (albeit Temporary) when I clear his system cache and Force ALL Thunderbird folders to Compact. Thank you!

If the above data is too vague, I can try to provide steps to replicate and screenshots on the next time this happens. Which is often. However, it is almost impossible to replicate on demand.

Additionally - I've read in other forums of similar issues where they were related to indexing and IMAP syncing across multiple devices. One person commented - that it was a deletion retention failure policy within Thunderbird. Something to the effect of, Thunderbird never really deletes emails when you press delete on the desktop application. The email is marked for deletion but all of the email headers and data is still stored in the active cache, or something like that. - And apparently, there is a lag in time that the server or servers update a deletion request if the email is deleted from another app. His primary email host is Comcast.net. So, he's using Comcast Webmail, Thunderbird Desktop, and iPhone 13 mail app. via IMAP, all for the same account that has about 10+gig of stored emails. Oh, he currently has threads turned off by request. Storage cache is currently set to 650mb.

Any help, suggestions or solutions are greatly appreciated. If you have any areas that need clarifying, I would be happy to take screen shots or provide additional data in order to find a valid resolution, as he's not interested in migrating to Outlook or any other Enterprise application.

Thank you!

How do I fix this error message? The address wasn't understood Firefox doesn't know how to open this address An error occurred during a connection to www.wsj.com.

   You might need to install other software to open this address.

www.wsj.com isn't the only website where this happens. It seems random on sites. www.youtube.com, www.wellsfargo.com. It all started after the last windows update this week. my other browsers weren't affected. Firefox is my preferred browser. Help me fix this.

I'm using Firefox 126.0.1 (64-bit) in Windows 11. I needed to download two files named index.html (in different source directories) from my company's content management system. Both got downloaded as index.htm. They were the right files... only the extension was changed.

I spoke to the person who maintains the content management system. They tested it and said it's not doing that, must be the browser.

That sounds fantastic to me, but I looked through the support messages here and found several about files whose extensions were changed on download; for example from .loa to .mp3. No explanations or workarounds, though.

Can anyone shed light on this?

Recently installed a "cleaner" app called PrivaZer. Ran the app and rebooted as part of the process which also included creating a restore point. Once system rebooted and logged in, pinned tabs were gone?! Using the created restore point did NOT restore the pinned tabs. Is there a way to recover the pinned tabs? Thanks in advance. FRANK

I have deleted 4 years of emails and yet you now say my mail box is 85% full. How can that be. What do I do to change this ? I need to maintain a system of emails and contacts for years at a time

For the last few months Firefox has released a stable version and a matching ESR version for OS's that are no longer supported. Firefox stable version had a major monthly release and a minor update as needed. For the next release scheduled in July I see a stable version of 128.0 with two matching ESR versions. I'm trying to understand the difference between the two ESR versions. The two versions advertised as ESRs are 128.0 + 115.13.
