About a week ago I started getting these update error messages stating "Update available - Firefox couldn't update automatically. Download the new version". I've also tried clicking "Learn more" on the error message but it's a dead link. Going into the settings for updates I am set to auto update, but when I manually check for updates it says "Failed to check for updates".

The help article on this issue simply tells you to download and manually reinstall Firefox, but I'm having to do this nearly every day. I work in IT myself so I know a "bandaid" workaround when I see one. Is there a solution to this issue?

I'm using the latest version of THUNDERBIRD for WINDOWS (now 10 HOME), but this problem has existed for years with previous versions of THUNDERBIRD and former releases of WINDOWS, both HOME & PRO releases. And, it seems to be very specific. When i receive e-mails from (especially) 2 friends who both use AOL as their e-mail client, when I receive them, the imaged files (or memes) are always 'converted into attachments, and what shows in the Body Text of the e-mails is empty boxes. Yet, when I get e-mails from others, including from commercial sources, if there are images within the Body Text, they are present there. This IS very annoying because many times the e-mails I get from these two friends are technical e-mails, with clarifying images as part of the Body Text. When I have mentioned this to them, their responses are that n one else complains, only me, and so the problem MUST BE at my end, but that doesn't make sense, since when I receive e-mails from others (Gmail, etal.) any included images are fully where they belong. ++++++++++++++++++++ Secondly, WHY is it that when there are threaded e-mails in the Sent folder, the ARROW to expand the thread appears at the left side, but in the Delete folder the ARROW appears between the title of the e-mail & the next column? This IS very annoying!!!! Also, when I'm in the DELETE folder, sometimes only two options appear at the right side: Archive Delete, BUT in other incidences, there's a plethora of alternative options, and the Delete option is positioned in a different place. More often than not, I click on the option to send it e-mail to the Archive folder, when I really wanted to Delete it permanently. Another major annoyance!!!! Thank you robert herold

I have been using Firefox as my primary browser for a very long time. Now, every time I start Firefox, I get a message that the update failed, and that I should manually download the update file and run it. I do so, the update appears to work, and Firefox behaves, until I stop it and restart again. Then I get the same message. I looked online - it appears that others have had this problem, but no clear solution. I am not willing to use Edge, but am beginning to wonder if it is time to leave Firefox. I would appreciate a solution, preferably a reliable one. Thanks, Joe Purvis Email hidden for privacy reasons

WIndows 11 64, AMD processor, 64 GB ram. Connected via ethernet and fiber. NordVPN, and Bitdefender (neither of which has produced any error messages).

Windows 10 22H2, Thunderbird 115.5

Thunderbird periodically loses my saved passwords (11 accounts) necessitating the re-entry of said passwords. This has been happening for about six to eight months.

I have searched for solutions and have tried deleting the pkcs11.txt and secmod.db files but the problem reoccurs. There is no rhyme or reason as to how often this happens. If I new where the passwords were stored, I could copy the good password file back into the thunderbird directory.

Any suggestions would be greatly appreciated.

Thanks.

Thunderbird runs slow...ie when I type an email I can easily type faster than thunderbird will accept characters....(this does not happen in other applications)...this happened about a month ago, and then stopped ( I have no idea why)...but the problem is back. I am running Ver 115.10.0 build 2024012173147. Rebooting windows 11 makes no difference.... I just tried to enter Troubleshoot mode and thunderbird stopped responding....Top line says Mozilla Thunderbird (Not Responding). Thunderbird is connected to my gmail account. ...and I run IMAP....with 'store all messages on the computer', but thunderbird wants to load every email from the server'

Any advice would be appreciated Rick

im unable to progress further than this and it wont matter because im not interested in any email service that doesnt have at least and preferably more than 15gb storage like gmail. send reply to- [removed from support forum]

I have been struggling with this problem for about 6 months now and no-one I've asked has been able to help me. Even my computer guru failed me! I think it was after an update about last June when I started having this problem An nothing I've tried has had any effect. I had a Geek Squad guy on the phone with me for about 45 minutes to no effect. He said he'd never seen the problem before. I have business emails on that account so I don't want to risk losing them. Can anyone help me please? Christine

I've been using Thunderbird for years and have never had this problem. Since the upgrade today, after I run Thunderbird once and close it I can no longer start it up again. I have to reboot or use Task Manager to kill it in order to run it. This is on Windows 11. Please help - not an acceptable workaround for long. Optionally, how do I downgrade to previous version? I should know better than allow automatic upgrades.

Adding a couple images below, when it has started successfully it shows as one of the Apps in Task Manager. When I close it, Thunderbird drops into the Background Processes but doesn't end. I have to kill it here in order to start it again.

Hi I am a longtime user of your browser. I have version 124.0.2(64 bit) installed on three devices. First thing I do on opening it is to click on "about", which normally updates the browser, before I do any browsing. In the last three weeks, however, it has not updated on any of the three devices, rather, it says "Failed to check for updates". I have tried the workarounds suggested at your Help center, and nothing has worked. What gives, may I ask? Thank you

After just turning on my computer running Windows 10, I opened Firefox. I open 1 web site and noticed my computer showed a (16) prefix when loading Firefox. I opened the Task Manager and it showed that there were 15 instances of "firefox" running in the background. All showed a UAC Virtulization of "Disabled". But they also showed using 638.8MB of memory. I do not know whether these are necessary files that must run in the background or if the number of files indicates that my system has been hacked and someone else is in my system from outside. Any suggestions as to validity of these files running or how I might confirm that they should be running. I have noticed the number of excessive background files before but the number is never consistent which makes me fear I may have been hacked.

something apparently got corrupted in firefox.. i tried running update and i keep getting failed to update.. i have refreshed.. i have uninstalled and reinstalled ...nothing. i am sure there is a folder or file somewhere that is corrupted and i cannnot find it. because even when i uninstall and reinstall fresh. all my bookmarks are there .. how to i start a TRUE NEW install??

I did an Upgrade to a version of Firefox that would bypass those "Your Browser Is Not Supported" messages that apparently come from "Cloud-flare." I figured [naievely!] that my addons would "port" to the upgrade. They didn't. Is there any way [e.g., a putative backup file, perhaps] that would allow this?

Thanks in advance...!

I have Firefox 124.0.2 running on Windows 11. For some reason, I can't update Firefox. When I manually down load the update file, it appears to run Ok, but the version doesn't change. If I go to settings and click on "Check for Updates" is comes back and says Failed to Check for Updates. How do I fix this?

It has been observed that when a user uses the Firefox browser and tries to download a DDD file, the file format is .pdf instead of .ddd. In the devtools, it was observed that the content-type is text/plain in the response to the request. I changed the content-type to application/octet-stream, but the error still persists
