IF I SEND AN EMAIL TO MYSELF, JUST ONE WORD AS A TEST, I HIT "SEND", AND IT IMMEDIATELY GOES AND ARRIVES, AS PER NORMAL. FINE. IF I SEND EXACTLY THE SAME ONE WORD EMAIL TEST TO, FOR EXAMPLE, MY WIFE, OR ANY OTHER INDIVIDUAL RECIEPIENT, IT TAKES A LONG TIME TO EVEN SEND. I GET A PROGRESS BAR AS IF I WAS SENDING A LARGE RAW FILE OR SOMESUCH. LIKEWISE IF I SEND THE EMAIL TO ME AND CC IT TO ONE OTHER PERSON IT TAKES AGES TO SEND. ONLY AN EMAIL TO MYSSELF ALONE WORKS AT THE USUAL SPEED. MY BROADBAND SPEED IS FINE. I HAVE USED THUNDERBIRD FOR YEARS ON DIFFERENT LAPTOPS AND DIFFERENT COMPUTERS WITHOUT THIS ISSUE. I DO NOT KNOW WHAT TO DO, CAN YOU HELP?

I keep having trouble trying to play a video on YouTube. When I try and play a video on You Tube the video will simply not play or take forever to start playing. What can be done to fix the problem? Can someone help. Thank you.

I'm a writer. In keeping with the Law of Primacy, my first work is usually my best work (after a few tweaks). I recently had to write an email response to someone for the Darling Bride and me.

I waxed poetic and wrote an incredibly diplomatic response to a most unpleasant situation. After completing the entire message down to our signatures, I selected "File" and "Save" to make sure it was all saved in the Drafts folder. That way, I could open it on another device and read the draft to her.

Imagine my shock when I opened it, only to find that the draft stopped in the middle of a word - while I was correcting a typo - and didn't save anything after that! Frantic, I went back to the computer I used to write it, hoping the entire email was at least saved locally. Nope! The draft stopped in the middle of the message, even though I had saved the entire thing.

Perhaps this isn't high priority for a lot of users... but for those few of us, it's a critical, fatal flaw that has to be resolved. I can't even imagine that I did anything wrong: I saved the message before exiting; and opened to find half of it missing. I love the idea of Thunderbird and its privacy features, compared with the data-mining big names. But I can't afford to lose data! This was a personal response, thankfully, and not related to my work as a writer and author. However, I have to trust my email client with the data I save to it. Any hints to prevent this are greatly appreciated.

When I am trying to access emails, a popup says to get certificate= imap.aussiebroadband.com.au:993 and confirm security exception. It will not allow emails to download

Today I started getting repeated notifications, every 5 to 10 min or so, that my McAfee subscription has expired, my credit card has been rejected, and that my computer is infected. I do not use McAfee, either in Firefox or on my computer. I use the security suite that comes with Windows. I cannot stop these messages from appearing, and disabling notifications from McAfee in the messages does no good, the notifications just keep coming. HOW DO I MAKE THEM GO AWAY? They must be SPAM because I've never had a McAfee product on this machine, EVER. Thank you so much for the help, Dave Templeton

When I restart Mozilla Thunderbird, my S/MIME certificate preferences under Account Settings seem to break.

When I initially select a certificate, both the common name/certificate name and the certificate fingerprint appear in the interface (see Working Settings.png). However, after restarting Thunderbird, only the common name/certificate name appears in the interface, and I cannot use S/MIME to sign messages (see Broken Settings.png). When I attempt to do so, I receive the following error message:

Send Message Error Sending of the message failed. You specified that this message should be digitally signed, but the application either failed to find the signing certificate specified in your Mail & Newsgroup Account Settings, or the certificate has expired.

To be clear, Thunderbird has no problem finding and using the certificate right after I set it—the problem only appears when I restart Thunderbird and the appearance of the certificate in the settings changes. The certificate does not expire until April 2025, so this is not the issue. The issue also occurs with another account using a different certificate that is also unexpired.

I am using Thunderbird 115.12.2 (64-bit ESR) on MacOS with Apple Silicon.

why does my hotmail in thunderbird sometimes get my emails and other times it says "Sending of password for user *********@hotmail.com did not succeed. Mail server pop-mail.outlook.com responded: Authentication failure: unknown user name or bad password"? Then it starts getting them again. It's totally random. Every once in a while it does it with my .live email too. Yet other .live and .hotmail addresses never have a problem? TIA

Hello! Thunderbird has stopped downloading messages from my Yahoo+ account. I can send messages from it OK. When I try to get it to download, it says: Checking Inbox for new messages... and waits at this point. Then I get: Host Contacted, sending login information... Then it waits for a long time. Eventually, it indicates "No messages to download", and then goes back to "checking inbox for new messages". If I click "Get Messages", a pop-up comes up with: "Error with account... and below: The account fischer94563@yahoo.com is being processed. Please wait until processing is complete to get messages." I've deleted the APP and downloaded and installed a new copy. No changes. Deleted and reentered my password with Yahoo. I'm at a loss to understand why this is happening, but it was working fine until recently. Any thoughts? Thanks. Kevin

Formatted my phone but playing videos still lags and stutters on Firefox browser on my Samsung. Only happens on Firefox, I've tested on Qwant, Duckduckgo and Brave and this problem doesn't occur. What might be the problem and solution?

It's interesting that sometimes the video plays fine until I unmute it. Sometimes the problem goes away after I stop and play or refresh the page. I often have to play the video on a different browser.

So, videos work fine on other browsers so I discart being a phone problem. But on my other phone this problem doesn't happen with firefox.

I've been for several months looking for help/answer/fix for this issue. And I've been with firefox for ever and I don't mind minor bugs and problems but this is starting to be a bit annoying and more and more I feel like I need to move on to a new browser.

Phone: Samsung S21 Ultra SM-G998B/DS Firefox: 127.0.2 (Build #2016028743) Extentions intalled: ublock

I'm having issues with videos loading on ANY webiste, YouTube ect.... This started happening very recently out of the blue. Videos work fine on Edge. Additionally, I cannot run Firefox in troubleshooting mode? It crashes. I tried "refreshing" and reinstalling Firefox to no avail. I am using AdAware AV and AVG anti viruses if it matters, I have tired disabling both and loading FIrefox, no changes.

Firefox is very dear to me. I use it on my computer all the time for how much more relatively secure it is from other browsers. But Android version is a hellish nightmare. When I open the app, even with no previous tabs on, it will not be responsive for more than 30-45 seconds for seemingly no reason. Same thing when I kill the app and start it again. If it does have open tabs, it will either not be able to fetch their sum number to be displayed on the top right corner until that aforementioned timespan passes, and/or I wont be able to remove/add tabs until again that period of time passes! This is a blocking issue that's been there for well over a year and a half, if not longer!

I have a Windows 10 pc, which is current with all Microsoft and manufacturer (Lenovo) updates. Thunderbird won't run since the last update. It just gives a message saying, "Your computer must be restarted to complete a previous upgrade of Thunderbird. Do you want to reboot now?" After several reboots, I have given up. A support forum solution from 4 years ago recommends deleting a file (global-messages-db.sqlite) at a location (C:\Users\user\AppData\Roaming\Thunderbird\Profiles\8charstring.default) that seems not to exist (hidden?) on my pc. What do you suggest? Thanks.

1) Youtube stalls out. Seems to be preventing or blocking the front ad from running, ... but wait long enough, Youtube video will play. This happens on all my computers, Win 7 and Win 10. Problem been going on the last 30 days.

2) In Win 10, Firefox browser never shuts down when I close it. Must go into Task Manager & do a "End Process" to kill it. I do make sure Microsoft Edge Browser is Disable. It wants to run all the time too. Thanks for your efforts. Been using Firefox since 2002.  :)

alright guys you need to fix your browser, it crashes everytime i try to play a youtube video.. i searched tou site for fixes and NOTHING worked. you vanilla version of the browser was perfect then yall had to go and do the microsux thing and screw it all up by adding this that or the kitchen sink. i have submitted numerous reports yet no resolution. if you guys dont fix your crap i will move on to another browser and recommend to all my friends n family to do the same.

For about a couple of weeks, there has been a lot of delay between what I type and when it actually appears. It's maddening! I have not changed any of my Firefox settings. I did a 'refresh' about an hour ago. I am not seeing any network activity that I cannot recognize. I d/l'd 'Malwarebytes' and ran it..."no threats". MS Defender has always been on & protecting me. I have never had this situation occur before and am hoping for some help (5 to 10 seconds to wait for what you've keyed in is not fun).
