I have internet connection. I can for example use firefox and read news.

All of a sudden just before when my laptops firmware was updated, I cannot read or send emails since yesterday. Even after the update is finished,when the laptop seems working otherwise fine, and i have rebooted my laptop Thunderbird has problems. Thundrrbird enters an infinite attempt to contact mail servers if i send or update inbox from 3 different accounts. One is microsoft365 the other is gmail and the third is one.com . All enter infinite attempts with no success at all.

Best wishes Josef

The 'Sent' file in my 'Mail' folder exceeds 3 GB (3,224,360,399 bytes) and is not being read in the TB Mail window. How can I reduce the size of this file AND save messages???

'Sent' message folder IS searchable!!!

I am seeing on a Windows 7 unit that I can update to version 115.19.0esr, but I tried to use the Google search tool to check what that version is all about, and nothing. I have tried various ways on pages of what I think is Mozilla and nothing. Where can I find information about version 115.19.0esr? Or has your browser in my unit been taken over by a malware type situation and I am in danger?

BTW, when I clicked on the "What's New" link I saw nothing about that "New" version I am being asked to update to. Oh yes, I am constantly seeing that 'Please Update' window, too.

So if this is a true version from your company/orghanization, where is the information about it?

Just in case you wish to know, I do have about ten screenshots of all that I have been running into as I have tried to find information about 115.19.0esr. And if you are going to inform me that you don't support Windows 7 so you aren't showing any information about an update your browser keeps asking me to update to, I am going to send a letter to some regulator and explain that somebody is not doing there job properly. If you keep nagging me to update, then you should be informing as to why!

Is there a foolproof way to ensure that cookies from critical websites are never deleted? Designating a website as allowed only seems to work by laboriously removing other sites under "Manage Data". Other cookie clearing methods, including via Firefox History, do not allow for exceptions.

Previously, when I downloaded a pdf file and I clicked open, I used to get small pop up window asking what app I want to use to open the pdf file with. Now, it just opens in Firefox. I don't want to view the pdf in Firefox. I can go to the files folder, find the file that j downloaded, select the three dots options menu and select open with. But thats too convoluted. I would like the previous functionality back of whenever I click open on a download pdf file, it asks me how I want to open it instead of directly opening it in Firefox.

Thanks for your help!

When attempting to sync my data on my android device it doesn't do anything. I'm currently in the account settings on my phone and when I hit "sync now" it just does nothing.

Please help me sort out my Thunderbird I have 2 computers, emails work on one and not the other I have checked the settings and both are the same and have same Virus protections on both computers I am at a loss to find out why please

when using a Fido2 security key Firefox browser requests a "security pin" to continue logging on to other website. I don't recall setting a pin. How to change or delete the pin issue?

Every time I run Thunderbird, it appears to lose its IMAP connection(s) after 10-15 minutes. I've tried varying the number of cached connections from 1 to 10 with no difference in behavior.

Restarting Thunderbird will restore connectivity temporarily, until the entire process starts over again.

It seems to be correlated to saving a copy of sent messages. The sending process times out while the message is being saved to the Sent folder after the SMTP sending is complete.

Once this happens, new mail doesn't appear, moving mail between folders has no effect, and some (but not all) messages can't be retrieved from the server.

I just updated my OS operating system on an IMac and got an error message that the Thunderbird app was corrupted and needed to be removed. I installed a new version of Thunderbird, but now I only see emails from about the last three weeks from my Webmail account. Previously, I think Thunderbird was saving messages on my computer. Does anyone know how to retrieve my old messages dating back a few years?

Last night the 15th January 2025, the firefox decided to update, buy it self closing the browser, however when it restarted it now comes up an Error, something along the lines of 134.0.1 and 134.0 MinVersion, if you have seen this you will know what I mean, it suggested to reinstall firefox, with that I did and I tried to porting all the setting and data and every thing, however it didnot import.

Where can I find the previous version that generated the error to start the import again... as there are links that I simply can not get any more

Cheers

Thunderbird stopped working. I received the following message - "Add Security Exception You are about to override how Thunderbird identifies this site. Legitimate banks, stores and other public sites will not ask you to do this. Location: smtp.optusnet.com.au:25 This site attempts to identify itself with invalid inforation The certificate belongs to a different site, which could mean that someone is trying to impersonate this site

Permanently store this exception"

I have clicked on 'Confirm Security Exception" but I still can't send or receive emails.
