In AM of 05/23/25 my Thunderbird mail downloaded to my desktop just fine. By afternoon of same day I get an error message (see attached) saying that it is unable to write to my mailbox. Error has continued for almost 24 hours now (thru 05/24/25 AM). I can get the email account on my phone through another program, but I like to save my important mail to my desktop storage. Please advise. (I did nothing to change my Thunderbird configuration on 05/23/25 that would have generated this message.)

Samsung S25 Ultra Android 15 Stock Rom Firefox v138.0.4

Firefox cannot play jwplayer streams and any other auto quality streams (youtube working) Always this error (This video file cannot be played.(Error Code: 102630) tried everything possible Drm content enabled Remove all my addons Reset all my settings But still no luck...

On Chromium-based browsers works Gecko-based browsers not working...

every time I try to log in to my hotmail account, I get this: "Please retry with a different device, use a VPN, or other authentication method to sign in. For more details, please see https://go.microsoft.com/fwlink/?linkid=2317517" this has started today...have been using Hotmail and Firefox for years, now all of a sudden this happens? why isn't firefox allowing me to use hotmail?

I'm running Thunderbird 138.0.3 (release update channel). I had an update in the past few days and now it is having a problem. Thunderbird starts OK but it I use another program for several minutes when I go back to Thunderbird its window is not visible. Looking at my system monitor Thunderbird is using a lot of CPU. The only way I can proceed is to kill Thunderbird from the system monitor. No crash report is generated. Running in safe mode does not help.

If I run Thunderbird from a terminal I get: $ thunderbird [64132] Sandbox: CanCreateUserNamespace() unshare(CLONE_NEWPID): EPERM ATTENTION: default value of option mesa_glthread overridden by environment.

This seems pertinent as it it to do with graphics but the web seems to suggest it in not important.

I have copied the Troubleshooting information to a text file and so can share it but it is quite large does not seem appropriate to include it here.

Any help gratefully received.

A few weeks ago, just after I tried to delete the cache and tracking cookies from Firefox (using AVG TuneUp, which seems to have taken more than I asked it to remove), my browser started refusing to load any new sites, or reload inactive tabs, once I had been using it for about five minutes after rebooting it. It also crashes completely when I try to download or upload anything after that point, which is irritating but does mean I have some crash reports to share (bp-5a7c5f6e-0d55-451a-8b2b-15b360250524 is the latest one). I've tried everything I can think of or find on the Internet - Troubleshoot mode, disabling and re-enabling hardware acceleration, refreshing the browser, uninstalling and re-installing it with and without restarting the computer in-between (which seemed to work for a while), culling tabs (although, if I'm reading the crash reports correctly, lack of memory isn't the issue after all; certainly, Chrome doesn't have the same problem even when using more memory than Firefox did), even running diagnostics on my computer's RAM and hard drive - but nothing's fixed it. What might be going on, and how can I solve this problem?

I am no longer receiving calendar notifications for events which are entered as "all day" events on my Google calendar.

I had a similar problem about three years ago when I wasn't receiving notifications for ANY events on my Google calendar. I attempted to solve this problem in a similar fashion by uninstalling/reinstalling Thunderbird then disconnect/reconnecting Google Calendar as discussed in the following link, but the All Day events' notifications still are not appearing.

As a debugging step/temporary solution (so I don't miss notifications), I have integrated my Google Calendar with Outlook, and am receiving notifications correctly with that app, so the problem doesn't appear to be on the Google end.

Hello folks, This has been a normal part of using Thunderbird for years, One of my Gmail accounts takes forever to synchronize... Eight or ten minutes... Strangely today, it's two of my other Gmail accounts that are taking very long.... Thanks ! Craig in Seattle

Have tried all options to get the pop up to show, including calling Apple…no luck..I even tried the advanced settings option typing about:config in address bar…doesn’t work. I enjoy Firefox but this may cause me to switch. Please help. Steve Destintider@email.com 850-585-751

Здравствуйте. Что произошло с браузером. Почему не загружаются страницы, а открываются те, которые открывались когда-то раньше? Мне сейчас постоянно жать на кнопку обновить страницу? Что вы сделали с браузером???

Hi, I recently had an office location change and post that in my office laptop, Thunderbird cannot authenticate with outlook and collect mails from it. IT team tried syncing the password from their end, and we tried a million other things like checking server settings in Thunderbird etc, but nothing is working. It just says "connecting to outlook.office365.com...." and is stuck there.

I'm using Proton VPN. I have the split tunneling set to allow non-VPN connection for thunderbird.exe . It doesn't work. I have a different app that needs split tunneling and it works fine, so it's not the way Proton VPN handles split tunneling. I'm wondering whether I should use a different exe as the split-tunneled one. I see 8 other exe's in the same folder. Perhaps one of these is the one to set-up for split tunneling. BTW I had exactly the same problem when I was using Nord VPN.

Thanks,

Tom

a few months ago, i built a new computer and upgraded to windows 11. but i have been having a bug where after resuming use of a firefox window, i will at some point lose the ability to left clicks links or to type in any fields on the page. for my mouse, i can still properly left click web buttons, like the youtube players, and i can left click tabs to switch between them. right and middle click still work correctly as well. for the keyboard, i can use keybinds on my keyboard (ctrl-tab/ctrl-shift-tab/ctrl-a) or hit space bar/page up/page down to navigate, but typing in fields just doesnt work. this bug happens after some random point of using the program, so it could happen after 10 seconds or 10 minutes.

the only way to fix it is to switch to a different program momentarily, whether that be alt tabbing to a non firefox window or clicking the desktop. ive just tried switching all my extensions and everything off with troubleshoot mode, but still experienced the bug. ive also tried different keyboards and mice in different ports and had the same issue persist, so i dont think its my peripheral software since i used generic keyboards too.

does anyone have any suggestions on what could be happening here and if anyone is experiencing the same issue? its very frustrating

I'm a therapist and within the last week (maybe since an update?) when I try to do a telehealth session from any website - Ensora Mental Health (my EHR), Simple Practice, Sessions by Psychology Today, Google Meet, Zoom - the client can see me but can't hear me, and I can hear them but can't see them (black screen).

I've checked all video and microphone permissions, Microsoft and all drivers are updated and mic and camera are functioning (they can see me). I tried changing the enhanced tracking to add exceptions for the sites (didn't work).

Please advise.
