This is sent as feedback only. The problem is happening on two different accounts (separate computers) of ours - again, since the last Thunderbird update. If it gets worse, I will try to re-install Thunderbird.

The download manager is overall bad... 1. You can't see download progress in the app. 2. You can't pause or continue download. 3. Your download instantly fails if you close the app. You can help by fixing these issues, if the app is closed pause the download to be resumed later. I look forward to an urgent response and solution to these problems, I just joined the Firefox family so far the experience has been great, it would be a shame if I have to get another browser to handle my downloads.

I have been using two Firefox browser windows a lot recently. Suddenly the response time to a request to open new window went from immediate to 20 seconds. Initially that meant I hit the "new window" button 10 times to get any response which meant browsing was interrupted for the next 5 minutes by the appearance of yet more new windows at 20 second intervals! Has anyone any idea about what has happened?

both my wife and I use TB on each of our machines mine is Windows 10 hers Windows 11, It has been fine for a while, but her machine sometimes shows a blank email that is fine on mine, by highlighting the folder and right-clicking and selecting folder properties and selecting repair folder this has resolved her issue.

Now however she has blank emails again, when selecting folder properties nothing happens no dialogue window appears, from the edit drop-down menu you can normally select folder properties as well but that option is not even there.

when she does right-click she has options which are from other drop-down menus as though the whole menu system has become corrupted. is there a solution to this or do I need to reinstall, if I do how do I keep all of her current emails and archives which go back about 15 years?

both on version 128.3.0esr (32-bit)

Using Tbird 78.14.0 (64 bit) with Windows 10. I can no longer access the Page Setup screen properly. I suspect it's because I accidentally put a very big value in for the top margin. The print preview for even a short email says it's many pages, there's no text visible on any of those pages, the only part of the Page Setup screen visible is OK and Cancel at the bottom, and I can't get to the top of the screen. I've tried closing and re-opening Tbird to no avail. How can I get to the top of the Page Setup screen to fix the problem?

Firefox gets updates frequently and that's good. But with every update an extra tab is opened like this one: https://www.mozilla.org/nl/firefox/131.0/whatsnew/?oldversion=130.0.1&utm_medium=firefox-desktop&utm_source=update&utm_campaign=131

How can I tell Firefox that I know how to find it in those app stores if I was using any of them? Or that I know how to find anything that I need on the Internet?

Why this aggressive promotion? What is the business model behind those free apps?

Hi all,

as per subject, with Thunderbird 128.3.0esr in Multiweek and Month calendar views I can't move elsewhere an event with drag & drop, while I can do it in Day and Week views: am I missing anything?

Many thanks

Hi Guys, I'm using a Samsung S22 Ultra, and recently, when browsing many websites on Firefox , I'm encountering a flickering blank white screen. Most of the time, the content is invisible, but if I scroll up or down, I can see bits and pieces of the site.

I believe this started happening after the Android 14 update.

Is anyone else facing this issue? Any known solutions?

Problem

I am trying to index a large IMAP mailbox. The indexer seems to be working fine then always stops while indexing the 'Archive' folder (~27k messages). Gets to a certain % and stops. This is the first time I have tried to index this mailbox.

Steps I have tried

• Close and re-open TB
• The indexing will restart happily and will index new emails but will still get stuck at some point during the Archive folder
• Deleted the global-messages-db.sqlite and attempted rebuild as per here
• Repair folder (Archive)
• The percentage it 'stops' at will vary if I have done one of the above steps (e.g repair) but if you just close and re-open it always appears to stop at the same place.

Errors/Debugging

When it stops that co-incides with the following error messages (This is repeatable): (Sorry I don't know how to format code blocks on this forum, trying standard MD)

First:

A user (u758982) reported similar error messages in This bug report

However the bug reported (and now apparently fixed) related to:

TypeError: aPart is null MimeMessage.sys.mjs:142:7

Which in the case of u758982 followed the messages I have above.

I do not get the MimeMessage error.

Setup

Thunderbird 128.3.0esr (64bit) on Mac OS (14.6.1).

My thoughts

I presume there is a particular e-mail in that folder which has some kind of issue or error that causes the indexer to halt. I presume it's in some way related to calendar (e.g. and ICS invite or something with a formatting error) as the error messages seem to indicate that. Unforuntately I can't identify which e-mail it is or I'd probably just deal with that.

I'd appreciate any help in troubleshooting - if it's an error on my side or can be easily fixed (.e.g identify the e-mail!). Happy to provide more details as needed.

Thanks in advance.

Note: this was originally posted in the Thunderbird Reddit but appears to have been auto-removed. I'm unclear why so posting here instead.

Hi, I recently updated my browser and am really disappointed that a previous solution to remove this frankly useless button was made obsolete. The correct way to have handled this on the road from 106 to now is to include an option in the right-click menu to remove said button. This option - while you can read it in the menu - is simply unclickable. This useless button that just hogs space like the toolbars of old is unable to be removed at all, as fiddling aroudnd with a userChrome.css file also didn't remove it. I would like either a concise way to remove that button that actually works or the ability to use my other mouse button to do something about it.

Hi,

we found such an oddity. We use a PGP key linked to the mageo.cz domain (the key is for addresses <somebody>@mageo.cz). Recently, importing a key in Thunderbird takes a very long time (the search on the keyserver is unreasonably long (tens of seconds) both when the key exists and when it does not exist). It seems to be some kind of anomaly only for this domain. For other domains, searching/importing the key is fast. A direct inquiry (through the www interface of the Hagrid keyserver) is dealt with promptly. The problem concerns only the search for the key via Thunderbird and only the mageo.cz domain

Thanks for the check/fix! Mira Krejci

Firefox won't connect to this site I just updated it to the newest version. It works on edge, chrome. It says The page isn’t redirecting properly

An error occurred during a connection to fordauthority.com.

I am a new user of Thunderbird. I have 4 email accounts. I am receiving multiple copies of emails both on my desktop and also on K-9 on my phone.

From reading the various entries on this support site I note this is a known problem. I have not found any posts that offer a solution.

Is there a solution? Do I need to run diagnostics to clarify my issue if so what diagnostics?

Thanks in advance.

Regards,

Mike Duffy
