This is a recurrent problem. I'm online with many tabs open, when all of a sudden they disappear and when I try to recover them by going in "history" [using the three lines at the top right of screen], and then selecting "recently closed tabs", and then try the "restore tabs", nothing happens! Previously, this had worked to offer me a way to reopen those tabs one-by-one, but now it doesn't restore anything. ALSO, I used to be able to shut down my computer, wait a few minutes, and then restart it, and would be offered a "restore session" option when the computer restarted, but that didn't happen today even after trying this twice.

I was once shown how to restore tabs by going up to the top right of the screen, but cannot remember how to do this. Can you please help me from loosing tabs, and my mind? Thanks.

Hello,

Tbird 153.0 (64-bit) on Windows using the Owl extension for microsoft authentication.

Everything was working fine till about 1 week ago. Apparently Cisco changed something and now I'm getting a TBird browser prompt that our Multi-factor authentication(MFA) DUO needs 'local access'. This is coming up in the 'captive browser' (I believe that is the terminology). This is the message:

Duo Desktop needs permission to access your local network.

Duo uses local network access to communicate with Duo Desktop. When prompted by your browser, please allow this permission.

I never really get a prompt to respond to this in Firefox or any other browser.

If I continue I'm dead in my tracks with this (also in the internal captive browser):

Allow local network access

Duo uses local network access to communicate with Duo Desktop

   Click the site information icon left of the web address in your browser.
   Click the toggle next to Local network access to allow access.
   The page should refresh automatically and allow you to continue.

This link is provided which isn't really helping:

Does this sound familiar? Can TBird use firefox instead of it's captive browser or allow the captive browser local access?

Thanks in advance!

Has anyone seen this behavior? Is it really a browser issue or an extension one? Is it a config issue or a bug? I'm juggling 2FA settings on slack for a per workspace basis, plus to Bitwarden confusing different workspaces I'm also having issues with saving updated passwords into Bitwardens vault I'm also logged into my Mozilla account I'd like help troubleshooting this, thanks

While Using Youtube : from the starting page (that comes up with multiple Clips displayed), I attempt to do the following: By selecting Open Link in a new tab, or Open Link in Split View (So I can Watch a specific clip without loosing the original displayed clips on the starting "face Page") ...the selected Opened Link Immediately Becomes Greyed Out And Refuses to Play the the Clip. To watch that clip I must close the video clip that I selected to then return to the original opening page to then Move the pointer back over the smaller box-clip that I want to watch, leaving the pointer on that clip is the only way to watch the clip. This Just Started Happening Recently...... This is Happening Every time..... Apparently, if you want to watch ANY of the displayed clips from a Start "Face Page" you can Only watch by hovering the mouse pointer on that specific Small Box Clip on the starting page...I can't bookmark that page without selecting the page to another Face Page, which then looses the smaller multiple clips on the original face page that I started on.

Thunderbird had been working great for both of us until after my wife stopped checking her emails for a couple of months. When she later opened the program her inbox started downloading hundreds of emails (very slowly) until her inbox contained well over a thousand. I started to delete the unwanted ones but it went very very slowly. I finally whittled it down to a few hundred but the program continues to run very slowly in all phases. In one instance, it took 11 minutes to delete 39 messages. Downloading and sending are not much different. I've done virus scans, checked settings, restarted the computer etc., all to no avail. And when we switch users, my Thunderbird email runs perfectly. I also contacted my internet provider (Spectrum) but they said it had to be a program issue. How can I restore my wife's email to normal function? Thanks, Joe S.

I'm trying to set up Thunderbird to use for my email ([redacted] @icloud.com). I have an iCloud account and get my email with a browser going to iCloud but I don't know of a password specific to my email account. The password that I use for Apple iCloud does not work. What do I do? Thanks. Ed

When trying to access my Tablo units via my.tablotv.com, the browser appears to see the units (or perhaps it is using prior access data, I don't know). But when selecting a Tablo unit to connect with, the result is a "continuing" message with the usual circle, but then nothing else-- neither the expected successful connection nor the usual "problem connecting" message when something is wrong. I can still access the units as usual using firefox on my Chromebook, which I presume hasn't updated Firefox the same way. These are the older Tablo units, not the different system they are selling now.

I'll attach a screenshot. I did try "repair"ing Firefox using the built in Windows functionality, but that didn't seem to change anything. I was thinking of trying to uninstall firefox and reinstall it, if you think that might work. Let me know if you have any suggestions. Stephen Hedges

It was working fine on the new computer until yesterday. Now I get a pop-up box that says: ' Unable to connect The connection was refused when attempting to contact localhost.

The site could be temporarily unavailable or too busy. Try again in a few moments.

If you are unable to load any pages, check your computer's network connection. If your computer or network is protected by a firewall or proxy, make sure Thunderbird is permitted to access the web.

gerald.r.vargas 4. Aug. 2026, 08:23 GMT-6 Hi, this morning for some reason all the tabs I had open couldn't been loaded. Refreshening the page didn't help either. So I decided to shut down and restart my laptop.

Unfortunately after restarting Firefox only one page and its tabs have been reloaded.  All the others were gone. 

After trying about:support and session:restore it didn't help either, because only the 4th of Aug. was available. Is there a possibility for a session restore from the 03rd of Aug? or the previous days? If anybody has an idea, how to do so, please let me know.

Many thanks, Gerald R. Vargas

Any search entry gets the following return:

Secure connection failed

an error occurred during he connection to oaik.lindantz.com SSLreceived a record that exceeded the maximum permissible length

error code SSL-eror-rxrecord-tooo-long

etc etc

After your security fix this morning, I discovered that I can't access my earthlink inbox. I keep getting the login page, and when I try to log in, the login page is all I get. I can, however, access my earthlink inbox on Edge. So I wonder if there was something in your security fix that is creating this problem on Firefox. How to fix this?

Can you help me repair my FireFox Browser? The shortcut did not launch the browser. It stated that the file had moved or was no longer working. It still appears in my App folder but the only option is to uninstall it. I have a great deal of short cut tabs and all my stored passwords. How do I repair this? If I re-download Firefox will it access all of my stored information and preferences?

Hi! I am having an issue with displaying sent mails. As you can see in the screenshot (cropped for privacy), I have selected the option to "Place replies in the folder of the message being replied to", which to me means that eg. a reply I sent will both be shown in the "inbox" folder in the message thread, as well as in the "sent" folder. However, it only shows up in the "inbox" folder. Why does this not work?

Thanks!

ich benötige die übermittlung, da das chronic dieses eingestellt hatte: die auffindung der www´s durch das vorgehen bei dem umstellen der mozilla-umsetzung bei der neuinstallation. durch dieses hatte ich die www von einer bestimmten auffindung nicht (ich kann die www gern durchgeben: frau, bdsm, in der nähe, aber ohne kommerziellem hintergrund !).

Hi, in this year I have sometimes problems with Google meet on my T480 notebook. I could not define any reason or what could be connected to this behaviour.

Start of the meeting is usually ok, but by time it starts to stutter. Video, audio and other callers stop to understand what I am saying. I have no issue with Chrome. And camera seems to be much better with Chrome. I use ocassionaly MS Teams and when I am in Firefox, it happened too. The main issue is, that it's unpredictable. It's not related to if I share the screen or not, or the others. It can be just simple call with camera off. And it happens sometimes, but often. So I learned by time to join meeting with Chrome. I tried to shut off extensions without positive result.

It is interresting, that it's working like that last several months. I started to use google meet in 2024 and it worked well all the time until this year. Hardware acceleration is on, I think I already tried to shut it off. I use ESET, that's only thing which occurs in my mind, what can be relative to this issue. But only in Firefox? Any advices?

when i use Chrome or edge to access yahoo email I can write & edit. when using Firefox browser; I cannot write & edit/highlight/change text colours etc before sending. tried deleteing & re-installing Firefox . please help. Driving me crazy rsvp

Environment:

Thunderbird: 153.0.2esr (64-bit) Operating system: Windows Occurs with multiple email accounts Reproduced on two different computers running the same Thunderbird version

Description:

After updating Thunderbird to version 153.0.2esr, released on 4 August 2026, emails can no longer be dragged and dropped from Thunderbird to the Windows Desktop or any folder in Windows Explorer.

The problem occurs with all tested email accounts and folders. It has been reproduced independently on two different Windows computers using the same Thunderbird version.

Saving an email manually with Ctrl+S works correctly and creates the .eml file. Normal drag-and-drop between folders in Windows Explorer also works. Only dragging an email from Thunderbird to Windows Explorer fails.

The issue also appears to affect third-party applications that use Thunderbird to create or send emails automatically.

Steps to reproduce:

Open Thunderbird 153.0.2esr on Windows. Select an email in any account or folder. Drag the email to the Desktop or another folder in Windows Explorer. Release the mouse button.

Actual result:

The email is not copied or saved to the selected Windows folder.

Expected result:

Thunderbird should export the email as an .eml file in the selected folder.

Additional information:

Ctrl+S successfully saves the same email. The issue affects every tested email account. Thunderbird extensions were disabled, but the problem remained. Thunderbird Troubleshoot Mode did not resolve the issue. Restarting Thunderbird, Windows Explorer and Windows did not resolve it. Thunderbird and Windows Explorer are not running with different elevation levels. The problem was reproduced on a second computer after installing the same Thunderbird version. No relevant error is shown in Thunderbird’s Error Console when the drag-and-drop operation fails. The issue was not present before the recent Thunderbird update.

This appears to be a regression in Thunderbird 153.0.2esr affecting email export through drag-and-drop and possibly Thunderbird’s integration with external applications.
