I am attending college classes on line, I frequently have 4 tabs pinned, and 3-4 further tabs open. Without any discernible pattern I can fathom, Firefox will close everything. I have no add-ons to remove, update or restart. I have no plug ins to remove, update or restart. My drivers and Windows OS are all up to date.

I ask my Firefox to delete my history and clear the cash when it is closed, so it takes me roughly 5-20 minutes to log back into everything I'm doing for class or my personal life when this happens.

Upon researching this matter today, all the fixes I can find involve removing add-ons and plug ins. Or updating them. Or turning them off. I have none to try this fix on. The advice on the main page says to check that all system are up to date. I have checked, they are.

Hoping someone has some advice. Thanks!

Hello, Since the update to Thunderbird Supernova from version 102 upwards, emails in several email folders are automatically deleted or hidden. The properties in the respective folders are listed under Retention rules: Do not delete messages.

The emails displayed in the folders no longer correspond to the contents in the folders. Example: A folder displays: 7, properties in the same folder displays: 1226 with 447 MB. It looks similar in the other folders.

How can I ensure that all available emails are displayed in Thunderbird again?

A repair with *.msf does not help.

Many thanks for your support. Erwin

I have never needed to see every single email in my inbox when I first open Thunderbird but I'd assume it trying to load everything is why it freezes for a few minutes every time I open it.

Unable to open OR uninstall Firefox. Error Msg: the procedure entry point Flush could not be located in the dynamic link library C/Prog Files / Mozilla / Firefox / xul.dll

Huge thanks for any help!

About 3 months ago when logging in to my bank account on a windows PC using Firefox, the password was accepted but the account failed to open due to an error. Previously it worked like a charm, but my bank updated its security and it hasn't worked since. However if I perform the same operation on Google Chrome it works. I have a similar experience on a few other web sites. Is there something in my Firefox settings preventing this from happening? Cheers,

Hello, I'm using Thunderbird (and before Netscape Messenger) already 30 years. With this new version 115.4.1 (32-Bit) I'm now experiencing the symptom, that, when I reopen one of the mailboxes the focus is not in this mailbox on the last read mail as it was always in earlier versions, it now focusses somewhere so that you always have to scroll to the point where you have been last time.

When composing an email and attempting to select an address from the 3 email accounts I use in Thunderbird, I am having difficulty selecting the email address I want to use. I'm clicking on an email address that opens Thunderbird in a compose window when this happens. It is a new issue but has been present a couple of weeks at least.

After loading the latest update, I can't send emails. Spamhaus is blocking them. this is an example of the error message... this is a business I have emailed before and they are in my address book, it is doing the same with other addresses

Sending of the message failed. An error occurred while sending mail. The mail server responded: Service unavailable; Client host [68.105.172.193] blocked using an77miiefpoizgkgitohtqs2qa.zen.dq.spamhaus.net; https://www.spamhaus.org/query/ip/68.105.172.193. Please check the message recipient "service@renaissance-printing.com" and try again.

The page layout and functionality has changed. I keep getting a message about imap! I have not made any changes to anything. It's just not working, i am very lost with it. Help please. John K-D

Since updating to 115.4.1 under Windows 11 (fully updated), Thunderbird regularly (about every 24-48 hours) freezes up and needs to be shut down with Task Manager. What's up??

Hello. Whenever that blue broader on the new tab appears, it doesn't let me type on my keyboard and doesn't let me switch to a different tab and open my folder on the desktop whenever I press my keyboard. Does anyone know how to fix this problem?

screenshot is attached.

Hello, as soon as TB Thunderbird was auto updated to the new version 115.4.1 (64-bit) 2 weeks ago, it keeps freezing randomly but often for several seconds when you click inbox folders from Any Emails I have: Private, Outlook, Yahoo, or Google.

It does also freeze randomly while I write emails or I check other folders. It take so much longer to deal with emails all together.

It tends to do it if the program has been opened recently but also in the midle of the day or while writing emails, for no reasons.

The previous version was also slower but was at least manageable.

What is going on? Any hints or different solutions are appreciated. Best Regards, Chris

I may have had this answered, but my email issues prevented me from seeing any answer.

I use Thunderbird with my gmail account. When I run Thunderbird on my computer, I don't load any emails (I do get emails on my iPhone). I get this error message: "Authentication failure while connecting to server imap.gmail.com." What does this mean and what should I do?

Recently I have had multiple occurrences of Firefox "freezing" and I have to shutdown the browser which then reports the fault to Microsoft. It seems to happen when I click on the button to Maximise the browser window. I'm running Windows 11. It generally does restore the browser tabs successfully but is nevertheless irritating and a recent phenomenom.

Hello guys...

I have problem in Mozilla Firefox 118 and 119 about company web app. There are several input[text] and textarea that can't type in them. But in other browsers are fine and Mozilla Firefox ver. 117 is fine too.

Btw, this app using AngularJS.

Any idea what happen and are there any solutions for this problem ?

Hello. Currently receiving the following error pop-up with Thunderbird 115.4.1 on Win 10 22H2:

"Unable to write the email to the mailbox. Make sure the file system allows you write privileges, and you have enough disk space to copy the mailbox."

This occurs when fetching new email from an sbcglobal.net POP3 account. Settings: inbound.att.net, port: 995, SSL/TLS, OAuth2. These settings have worked successfully for years until yesterday NOV 6 2023.

I have several other POP3 accounts all using the same settings shown above but none of them are triggering the pop-up error.

Can an expert please advise the specific conditions that trigger this error so I can determine where the fault lies? Example: Is this Thunderbird's interpretation of an error condition being transmitted by the email server requiring interaction with service provider? Is this Thunderbird's response to an internal problem like not enough disk space? (even though there is plenty)

A solution would be nice, but an explanation re: the triggering mechanism is absolutely required. Thanks.

While on michaels.com I click on a product, it goes to the product then immediately the screen goes blank. It also happens when I do a search, multiple products show up, then the screen goes blank. I don't have that issues on other websites. What is going on and how do I solve this issue?
