Firefox has been running fine for me for a long time but recently, like the last week or so, it has been crashing constantly. When I first boot up my computer, it will be fine for awhile and then it'll just crash. If I try to restart it then, it will either immediately crash or crash after a few seconds. sometimes it will hold together for a bit and then crash. I've had it crash when I've clicked to move to a new webpage, and I've had it crash when it is just idling on a webpage. I have already tried troubleshooting mode and it still crashed, so its not my extensions. Ive also tried to reinstall it and that has not helped either. Any help would be greatly appreciated.

This is a bit strange...

Thunderbird (v91.5.1, 64-bit, Win 10 Pro) connects to my POP3 account but doesn't download anything.

If I then pause Kaspersky (Internet Security) Thunderbird then connects and downloads emails.

I then re-start (un pause) Kaspersky and....Thunderbird continues to connect to my POP3 account and download files. If I stop and re-start Thunderbird I have to go through the Pause / un-pause process again.

Kaspersky is set to NOT scan encrypted connections.

It is set to scan secure traffic in Mozilla applications using the Windows Certificate store. I have disabled this and it makes no difference. I have also tried setting it to use the Mozilla certificate and installed that into Thunderbird...and it makes no difference.

All this feels like a Kaspersky issue except for the fact that once I have paused Kaspersky, and Thunderbird connects to the POP3 account, it continue to connect after I've restarted Kaspersky.

After this last update Firefox is really slow loading pages and has crashed on me multiple times, I have also noticed if the browser is up it slows other programs down now like when im burning a cd. Is anyone else experiencing this? Thank you

For the past week when I try to retrieve my email I continue to get this error message. Tried re-entering my email password but didn't make a difference. Checked the server settings - outgoing is showing this smtp.verizon.net, port 465 and server name shows pop.verizon.net, port 995. I have a gmail account on Thunderbird and works normally. Any suggestions?

I updated to Thunderbird 91.x.x several weeks ago, and now, every time Thunderbird starts, I get an error message "Either there is no mail client or the current client cannot fulfill the messaging request. Please run Microsoft Outlook and set it as the default mail client." See attached file. If I press OK or the X to close the window, I have to do this 18 times and then Thunderbird starts up normally. I have not mentioned this before thinking that it would be solved in more recent release but that has not happened. I am running windows 7 and do have Thunderbird set as the default for the programs it can open.

About the same time, Thunderbird published a note that it was adding a PDF function. This works, and opens the PDF but after 5 seconds Thunderbird crashes every time I open a PDF... and I have to go through the process described in the first paragraph to get Thunderbird restarted again.

When I type their information into the address bar I get the following message: You can't change the address book because the contact is in a mailing list. I don't know what this means or how this happened.

For approximately two weeks now I am sometimes able to send email in the early morning, but after several hours I receive the error message attached regarding excessive failed authentications. It seems to reset every 24 hours. Comcast has been no help. I am connecting to the Comcast servers through the Charter/Spectrum network at my second home in North Carolina. Since it works sometimes it seems unlikely this is actually a configuration or Thunderbird issue, but I'd love to hear any ideas. Tried disabling ESET NOD32 15.0.23.0 antivirus, no change Thunderbird version 91.5.1 (64 bit), but it hasn't worked properly for several updates, and as mentioned above I don't think the problem is necessarily in Thunderbird. OS is Windows 10, just updated this morning to build 19041

Dear Thunderbird Support,

I am representative for my company Likom Caseworks Sdn. Bhd., Melaka, Malaysia. One of my user has the special case. She used to be open messages in "a new message windows" instead of "a new tab".

Her problem do not occur every time she open messages. However, in some time, when she open messages in a new message windows, her main Inbox windows will closed up itself.

The proper practice for open messages in "a new message windows" should remain the main Inbox windows instead of close it up. May I know how to solve the problem. I had helped her to install to the latest version 91.3.1 but the problem do not solved.

Please assist.

The version of the Firefox 95.0 that it is the latest and thus we attached the picture here for tour further investigation.

Would you please help to check and advise for that? Thank you.

Why does Thunderbird not use the designated app/program in Windows 10 default options to open .MOV email attachments and only allows saving the file. It doesn't do this with mp4 files. Why with .MOV attachments????

My cursor dissapears when I use some type of maps - FlightRadar, Booking. I've tried to run in troubleshoot mode already, disabled all add-ons, unchecked hardware acceleration, changed theme, disabled webrender, nothing works. I've also checked for latest graphic cards updates, everything is up to date. More suggestions someone? Thanks

Every so often I get a pop up message that says a web page is slowing down my computer. I don't understand how this happens nor how to stop it. Can some one please tell me? Keep in mind, I am truly technologically-challenged. Please reply as if you're talking to a smart 2 - 3 years old...seriously. Thank you for your time and consideration.

In my settings I have enabled that FF asks me where to save files whenever I click on a download or choose 'save as'. This works... until it doesn't. For no reason and at random times Firefox stops asking me where I want to save downloads. It also doesn't download them automatically. It basically ignores any commands to 'save as' or download files like PDFs. The only thing that fixes the problem is restarting FF.

I'm on the latest macOS with the latest FF version, but this has also occurred on previous versions of FF.

Any suggestions?

Beginning yesterday after installing a set of fresh MacOS updates, Firefox is repeatedly hanging on my iMac. My computer CPU spins up and Activity Monitor tells me that the process trustd is having a field day, up to 99% CPU usage. Then Firefox stops everything and in the middle of something basic like opening a search engine page or scrolling on an already-open page, I get a spinning rainbow ball of death and have to Force Quit from the taskbar several times before it closes.

Here is what I have tried to resolve:

• Deleting and reinstalling
• Troubleshooting mode
• Downgrading to version 93.0
• Stopping and restarting the trustd process from both Activity Monitor and from Terminal
• Full deletion of all Firefox files from command line and installing 96.0.2.

The same problem keeps recurring. For reference, it's on a 2020 iMac running macOS Catalina (10.15.7), i9/16GB. My other machines are not affected. I have not yet upgraded to Big Sur or Monterrey on advice of workplace sysadmin.

Is anyone else seeing this issue with trustd? I am not seeing this problem with other software, just Firefox, but I can't figure out when Firefox calls trustd and what it asks it to do when it does.

Advice warmly welcome.

Hello,

I'm a faithful user of Firefox on Android, trying to avoid Chrome as much as possible... but the experience has been generally awful, with Firefox crashing randomly about 3-4 times a day, with no clear pattern of what might be causing the crash. Here are a few links to the crash reports; there seem to be several different bugs, which makes it difficult to troubleshoot or report (e.g. to bugzilla): https://crash-stats.mozilla.org/report/index/b9ad11c4-aed5-45e9-8c3a-82f020220127 https://crash-stats.mozilla.org/report/index/df324f27-dca6-48f2-aa04-8d04f0220115 https://crash-stats.mozilla.org/report/index/7154a4f6-659c-4e95-bf7a-e44e90220123

If no one here has a better idea of what might be causing this, I suppose I'll have to go through opening bug reports for every one of those...

Here are the facts of my case, now closed as duplicate.

I just remembered that heretofore, Firefox has automatically disabled Add Ons that were amiss. Rather than action DrMoishe Pippik's bifurcation stopgap myself, can't I do nothing — and wait a week or two — if someone more technologically skillful deduces the astray Add On, and Firefox disables it?

Hi,

When I first launch Thunderbird and click Get Messages nothing happens, even though I know that there are emails waiting to be downloaded.

When I click Get Messages a second time, the emails do download.

I have the latest version Thunderbird 91.5.1 on the latest Windows 10 - all updated as of 26 JAN 2022.

Any ideas?

Since 1/23/22, I have not been able to receive messages from pop.1and1.com on Thunderbird. I CAN receive messages if I use the IMAP interface. Far as I know, nothing has changed on either 1and1 or Thunderbird since that date. Can anyone help?

Thanks in advance!
