with version 91.9.1 (32 bit) it takes 12 to 14 seconds to send an email - same on 4 computers 3 windows 10 and 1 windows 11 this started 5/22/2022 after Thunderbird update

Random videos will not load following 100.0.2 install.

These symptoms started @ May 21. (See attached file "Recently installed")

This problem is 100% reproducible at: https://www.reddit.com/r/CatastrophicFailure/

Lenovo Thinkpad x140e Windows 7 (all updates installed) Mozilla 100.2.8174

Scrolling down the Reddit page, videos will auto-play when exposed, and stop when scrolled past.

A video not loading/playing will occur on different posts/videos, but will ALWAYS occur. Once this occurs some previously exposed / played videos, when scrolling up, will play when exposed again, and some will not.

This will also randomly occur on Youtube (also observed on Twitter a few times) when multiple tabs are open. Sometimes closing other open tabs corrects the problem. Other times closing Firefox and relaunching is required and is 100% effective.

I have additional diag data / Inspector log files and page source if needed.

Thank you in advance for your help and consideration. - LudditePro

I've been using Thunderbird for a number of years. I recently went back to using Windows from Linux, and am having difficulty with the Windows version of Thunderbird. The issue is when I go to set up my gmail accounts, I get a box popping up that should show my google account so I log in through there, but it hangs and never moves past. The pics below shows both the window that pops up that never changes and the server settings.

I've let it sit for up to an hour but nothing changes.

I've looked and haven't seen this question elsewhere, so I figure it must be something on my end. I'm using Thunderber 91.9.1 on Windows 11 Home OS build 22000.675. I'm not using any sort of VPN, and I've tried with Windows firewall both on and off, no changes.

Somewhere around FF 86, the print preview was broken so one only gets a tiny, unreadable print preview. For a while, print.tab_modal.enabled = classic experience (false) worked. Sometime in the last few months, that was taken away and no longer works. How now do we get a print preview big enough to see and make our choices about things like scale?

I note that I run Windows 8.1 (up-to-date), Radeon HD graphics, 1280 x 1024 monitor.

Back in 2019 I learned how to set Firefox so that a website opening a new window would always include standard menus (the website could not suppress them). Now I get windows without the menus and controls I need.

I used some combination of 

dom.disable_window_open_feature.menubar

   and

dom.event.contextmenu.enabled

These haven't done the job for over a year now.

How do I do this now?

Thanks in advance, Lawrence

p.s. I note that I run Windows 8.1 (up-to-date), but have a Windows 10 I could use if it would work better there (up-to-date).

Whenever I use web-applications that use WebGL or anything similar, they are always distorted. And yes, I have tried disabling Performance Settings, but that only slightly helped.

Hi!

I often send an email to 140 recipients via SMTP. Until recently it took 2-3 seconds. Now it takes about 2 minutes. My web-hosting company Simply.com is very insistent that their server is not the problem. I use TB 91.7.0 (64-bit) on Ubuntu 20.04.4 LTS. I am not sure whether TB updated itself when the problem started. Any help would be appreciated.

Our company email host uses Office 365 exchange. As of yesterday (26 May 2022) all emails were blocked to Thunderbird on our networked office PCs using Windows 10. We cannot send or receive email on Thunderbird (fortunately it still comes through to our iPhones). Our host hold us that Microsoft has "recently started blocking POP3 connections on software such as Thunderbird".

 How do we fix this problem so that we can continue using Thunderbird, which has our email records for some 10 years?  We do not want to use a Microsoft mail client unless we really have to!  I imagine we aren't the only ones with this problem, but I couldn't easily find it by searching help.
 Many thanks!

I have a lot of issues with my mailbox. Constantly have to repair folders because the wrong subject shows on the wrong email. A big one I had was my inbox getting bogged down, but I learned it doesn't like to have more than a couple thousand emails in it. I kept getting a "exceeded maximum number of connections" error but read something about too many folders, got rid of a few folders and that error went away.

1) What other kinds of tips are there for keeping TB behaving well? 2) I see that my profile has a lot of old files for old folders that don't exist anymore. There's also nstmp files and foldercache.json files. Should I delete all these types of things to clean up? Or should I just start fresh with a new profile and re-download all my email messages? I can't imagine how long that will take because sometimes folders download quickly but other times take forever and I'm not sure the difference. I just downloaded a 4000 email folder in a 20th the time of another 2000 email folder.

Hi I have my email on my server with my hosting company for various sites. Nothing has changed on this set up for years and now in the last week I am getting the message "connection to server "my site" has timed out." but only for the two emails associated with this one particular site. I deleted the smtp, deleted the incoming settings, added back, same error. The email is working fine on my other devices and the emails for the other sites are all working fine on thunderbird, too. Thunderbird is up to date. Any ideas?

After updating Thunderbird to the new version 91.9.1, most of my email messages disappeared.

An error message was displayed after updating to the new version. Thunderbird restart chashed and I started the program again, just to noticed that the messages were not anymore in the folders.

How can I recover my messages?

The last bunch of updates FF has only gotten worse. There are so many websites I use to be able to access and now they only function partially or lad weirdly that I am being forced to another browser. So sad. Why do they mess with something that worked?

Thunderbird non si apre più, da 5 giorni. Ho notato che il computer ha rallentato moltissimo tutte le attività e, dopo il riavvio perchè bloccato, Thunderbird non si apre più. Non compare neanche la schermata iniziale; ho provato con il tasto shift ed il tasto destro del mouse ad avviarlo come "amministratore", poi ad aprire la rubrica ed ho controllato tutto quanto possibile per le mie (scarse) conoscenze informatiche. La casella mail, sul server, funziona perfettamente; ma senza thunderbird non posso aprire l'archivio "storico", con centinaia di messaggi e continuare sul solo server è estremamente complicato. Ho provato anche a cliccare sull'icona da "start" (win10 a 64 bit), ma è lo stesso, nessuna reazione, nessun caricamento, come se non esistesse. Non so come fare, grazie

A couple users at our site intermittently receive a SSL_ERROR_BAD_MAC_ALERT error when navigating to Google in Firefox. This happens in Version 99.0.1 (64-bit) on Windows 10 computers. When the issue occurs, users can navigate to other websites without issues. Navigating to Google in a different browser works no problem. Restarting the browser will resolve the issue. Clearing cookies and site data has no effect. Users can also refresh the page after some time and the issue will go away.

Any idea as to why this is happening?

There are corrupt inbox sub-folders on our Rackspace account. Thunderbird will not 'get messages' and throws a 'SERVERBUG' error. Then proceeds to tell me to look at the server logs. Right! Rackspace is going to let me look at their server logs.

Anyway, Rackspace says this is a known Thunderbird bug. The 'SERVERBUG' error message is being generated by Thunderbird and there are no server log error messages.

FWIW Apple iPhone native mail client and Rackspace Apps web client also fail to open the corrupted folders. Only iPhone and Thunderbird generate consistent error messages.

Anybody got an idea what is going on here? I'd really like to check our mail.

Thanks

I am receiving this error message and have checked all the settings and have found nothing wrong with them.

Has anyone received this error and/or know how to fix it? Thanks.

Hi I don't know what has happened to Firefox, I used it all the time for many years, now I can't sign in to Outlook and have more problems than ever. It asks me to sign into Microsoft but all I get is a blank page. Firefox was always more colourful than other browsers that's why I used it and nothing you do to try to fix this problem doesn't work, it creates more problems than it's worth, that's why I use Chrome, but I do want to use FF. Not all of us are IT experts and can't do all these complicated suggestions every web site offers, so can you make it so much easier for us to understand and for example get Outlook to open automatically as it used to do, until you can fix this I will have to use another browser. I really do like FF but it's impossible. Geoff.

I have lost my IMAP and SMTP connections between Thunderbird v91.9.0 on Windows 10 and two Gmail accounts. One is a standard @gmail.com account and the other is an @my_domain account on Google Workspace. The experience is (almost) the same on both.

Any help would be greatly appreciated.

When I try to read IMAP mail through Thunderbird, I'm presented with a pop-up (apparently from Google) to log into the gmail account with the email address pre-populated in the "Enter your email" field. Curiously, the email address for the Google Workspace account is broken into two parts with the user name left justified in the field, the @my_domain right justified and a gap between them. This is not true for the standard @gmail.com account, where the field is prepopulated with a left justified username@gmail.com. I click the "Next" button and an "Enter your password pop-up (apparently from Google) appears, into which I enter the password and click "Next".

Then I see a pop-up (apparently from Google) which says "Mozilla Thunderbird Email wants to access your Google Account", with "Allow" and "Cancel" buttons. I click "Allow" and often (but not always) see a small pop-up (apparently from Thunderbird) which says "Authentication failure while connecting to server imap.gmail.com".

The experience on the sending side through SMTP is similar. Upon clicking "Send" in Thunderbird, I'm presented with the same sequence of pop-ups (apparently from Google) to enter Google user name, password and permission to allow Thunderbird to access my email. Then there is a "sending message" pop-up (apparently from Thunderbird) which never completes.

Here are what I think are the relevant Thunderbird settings --
