why is everything going to trash in thunderer but not in Comcast.net email what do i do o i eed to reinstall it and uninstall it

can not  do restore point

Thunderbird 138/139, Windows 11 Pro 23H2. While composing a message, after a few lines the app freezes. Both the compose window and the main TB window freeze. Only opening the Windows Task manager allows me to close them. This did not happen with earlier versions.

If I save the message every few seconds while composing I can get most of the message back and continue after restarting TB. This behavior is the same in both the normal and troubleshooting TB modes. I can't even find a crash log to send to Mozilla.

Where shall I look next?

Thank you!

Hi. For a long time, I've noticed that emails I send from home are sent, but those I try to send with the same settings do not get sent when connected to the Internet in 4 out of 4 cafes. My ISP, Zen, hasn't been able to explain why. I've tested whether Google VPN blocks it somehow, and it doesn't. I normally use Thunderbird. Today, I found that, in the same cafe, messages I tried to send using Thunderbird failed to send, whereas there was no problem with GMail, Proton Mail or Outlook. Any suggestions?

Hi,

Firefox version: 139.0.4 (64-bit) OS: Windows 11

I have been having issues where Firefox tab will just crash out for no reason it appears and it happens at random times and once the tab start to crash, and I restore it, it will crash again and again. The only way tog et out of the loop is to restart Firefox.

I have tried: Refreshing/Reset, Clearing Cache and History removing all themes, disabling extensions, disabling my anti virus. Turning off hardware acceleration didn't make any different.

I currently have 2 extensions enabled: uBlock Origin 1.64.0 and Bitwarden Password Manager 2025.5.0

In the about:Crashes I have reported them all and they seem to have the same type of reasons in the Raw data/Minidump which are: EXCEPTION_ACCESS_VIOLATION_WRITE EXCEPTION_ACCESS_VIOLATION_READ

Any help as to what to try next?

I have had an ongoing problem with Thunderbird being unable to log into the various mail servers that I use. I've tried repeatedly to solve this problem and have been able to cure it in the past by clearing the cache, but it recurs over and over again. I cannot keep wasting my time like this. I'm an independent contractor and I need to be able to use my e-mail client consistently. I've got work to do! This morning, it's suddenly decided that it cannot log into any of the three services that I use.

Is there a lasting solution to this problem? If not, please tell me and I'll move on peacefully, but please don't keep me chasing my tail for something that cannot be fixed.

So I was looking at Event Viewer and I have noticed that Firefox Default Browser Agent shows error with EventID: 5, aKa Access Denied.

I tried to google a bit, but couldnt find anything useful, or at least for me.

Then I went to about:config in FF and I have noticed that even if I didnt personally made any edits, when I clicked show only modified preferences, it shows A LOT.

So it makes me to wonder what exactly is this error and why my config have so many modified preferences, even if I didnt modify any >.>

Every 1 - 2 hours Firefox stops loading pages and I have to shut it down and restart it and restarting takes around 6 clicks on the icon to get it to start.

Also one time today I lost all my pinned tabs and had to manually restore them one at a time.

Using Ubuntu 24.04.2 and latest Firefox. Cleared cache but doesn't help.

Hello, Since the update on 24 June 2025, bookmarks are displayed in black text on a black background. Is this normal? If not, how can I resolve the issue? I had set it to dark mode, but even when I switched back to light mode, nothing changed. I would appreciate help from the community or Mozilla if anyone has a website address to contact them. Have a nice day.

I cannot for the life of me figure this out. Whenever I load a website that needs location (for example, Google Maps or my province's lottery) and enable location permissions, the websites come back saying they cannot find my location.

I have refreshed Firefox, disabled all Enhanced Tracking Protection, disabled all extensions, and have even ran Firefox in Troubleshoot mode - all to no avail. Is there any way this can be fixed? These websites all work on Chrome and Edge and work on my Firefox for iPhone.

Hi Guys, I have just installed Linux Mint 22.1 on a laptop and I am using Thunderbird for Linux Mint as my email program. The version of Thunderbird I have is 128.11.1esr(64bit). I cannot update Thunderbird to the latest version because it says "Updates disabled by your system administrator" How do I overcome this problem? Thank you.

On starting my laptop and going online I noticed that my sidbar bookmarks text has turned black, it was previously white as I use the dark mode for my browser, I have tried changeing my theme and the only way to revert this is to not use any themes and just have white background which I dont want, is there any way to change this and why has it happened, I have been thought both Firefox and Windows settings but cant find a way to change it?

Hello,

 I have Firefox 140.0 on Windows 11 23H2.  I just noticed that the Favorites Sidebar text and background are both dark.  The History Sidebar does not have this problem.  Changing either Firefox or Windows color scheme has no effect.  I'm pretty sure this happened with the latest update. 

Thanks

I have a rule that moves email messages from backups to a 'Backup' folder. I also have another rule that moves emails address to myself to 'My Mail'.

When I start TB 128.11.1esr in the morning my 'Backup' and 'My Mail' folders show new email counts. When I click on 'My Mail' the number on it decreases and 'Backup' increases. This happens with other rules on other folders.

So, my question is this behavior caused my 'Message Filters' being triggered when I click a folder or potentially a latent refresh of the folders new email counts.

Thanks

I love Thunderbird, I think it is an excellent product all round, but one thing that really, really niggles me is that it continually marks certain senders as junk.

I receive Emails from these senders all the time, and often miss Emails because Thunderbird has marked them as junk, and moved them to the Junk folder, which means I don't see them on my mobile devices (IMAP).

I've marked this sender as "Not Junk" at least a thousand times. Each time it accepts my tag, and moves the Email back to the Inbox. However, that doesn't last, as the next Email, or the one after, or the one after that, ends up in Junk again.

I've seen a few posts that protest - this is not Thunderbird's fault, it's your Email provider, but I've already crossed that one off the list as I have white listed the entire domain at the Email provider. So nothing is getting flagged from the Email provider, to hint that it might be junk.

I'm always on the latest version of Thunderbird, and I have adaptive junk filter logging enabled, but it is completely empty of any logs. I also have "Do not automatically mark mail as junk if the sender is in "collected addresses" & "personal address book". I have a number of entries from this domain in the personal address book, as well as *.@domain-name.com, though I'm not sure if that format is correct to capture the entire domain.

Any help on this matter, gratefully received.

In our work we use the cardbook extension; starting from version 95.2 it began asking the user for permission. I wouldn’t really like to explain to a crowd of users what to do with this request. Is there some way to grant these permissions without asking the user for them?

Every time I try to go full screen on firefox for the youtube site, it will quit the Firefox app, or turn into a black screen with a tiny bit in the corner, or go into the wrong orientation. After maybe the third to fifth try of full screening, it will finally work. I had this issue with the firefox app for all my phones (all Oppo, so unsure if this is device specific). Thank you for looking into it!

Issue Description: I'm encountering a privacy tab setting issue with the Firefox app on my Android phone. When I close the Firefox app, all private tabs are automatically cleared and not retained. However, when I previously used Firefox on an iPhone (iOS 11), private tabs remained open after relaunching the app.

Specific Questions:

1.Is there a setting in the Android version of Firefox to retain private tabs after closing the app?

2.Is this behavior due to Android's restrictions or Firefox's default configuration?

3.If no direct setting exists, are there workarounds (e.g., extensions or specific versions) to achieve this?

My mobile phone is: Nothing Phone (3a) Pro Android 15

Any advice from users with similar experiences would be greatly appreciated. Thank you!
