I'm having trouble with Thunderbird on my new Windows11 laptop. I've used Thunderbird for years and years on the old Windows10 one, but can't get it to work right on the new one. The version info it gives is "128.4.4esr (64-bit)"

Specifically two problems. (1) Every time it starts it asks for my yahoo server's password. Even though I check the box asking it to remember it, it doesn't. Under Settings->Privacy&Security (under Passwords)->SavedPasswords, the list is empty. (2) Second problem (may be same as first, but in a different form) Whenever I try to send an email message, it fails. It waits a long long time and then gives a popup saying "Login to server smtp.mail.yahoo.com with username bill.marshall@verizon.net failed." It gives me an option to enter a new password, and if I click there it doesn't let me enter the password again, just re-tries, again waits a long long time, then gives the same error popup. When I cancel, it gives a new popup saying to check the password and verify the 'Authentication method' in Account Settings (which I have done, and all looks OK).

Thanks Bill Marshall, bill.marshall@verizon.net

FF is my default browser. My computer is a new iMac (M3) desktop. I have used FF for several years without incident, until today. It opened normally, and then the familiar update pop-up said an update was available and invited me to re-start the browser. That requires providing admin credentials to the "Install the 'Helper tool' " pop-up, which I have done every time without incident, until today. A follow-on pop-up then asked if I wanted to allow Firefox to access other apps and devices, which I had never seen before. I said "No", and that was the end of my FF browsing experience. Every time I try to start the FF browser, it wants me to try to install the Helper tool; I provide admin creds, it goes away (fails), and the browser never starts.

I have a lot of bookmarked URLs and other browser-related data that are extremely important, and I cannot afford to lose them. Used Safari & Google & Mozilla helped me learn the location of the FF "Profile" folder. Navigated there and copied/pasted it (ends in ".default-release") to my "Documents" folder as a back-up copy. Downloaded a new instance of FF from Mozilla download page. Didn't open. Went to download folder, clicked the .dmg file, which opened a small pop-up. Followed the instructions to hold down the CTRL key while clicking "Eject Firefox". Nothing productive happened (no new FF icon). The old icon in the dock still doesn't start the app.

Would it be useful at this point to un-install Firefox (in Applications) and then try again to download a new version? If so, I would need help on how to make the old Profile folder (the back-up copy) available to the new instance.

Thank you very much.

You can give me some help in finding out why my Thunderbird account will not launch. It is VERY inconvenient to not have access to email. Thunderbird works on my macbook, and ipad but not my imac. WHY ????

My Firefox program completely crashed and would not restart. I had error messages like " couldn't load XPCOM" and "entry point not found", and "awake time".

Reinstalled new Firefox version. At some point it asked for a new password and I put in a new password.

Then it asked for encryption key. I entered it and it said invalid. Can I sign in with the old password and use the encryption key that I know is correct? Or change the password back to the prior password?

Otherwise how can I get to my profile to recover bookmarks and other info?

Please provide step by step instructions.

Thanks-- Peter M.

My email C/o THUNDERBIRD, has just started to stop, sending , my emails. When I try to send, it comes up with a message box that says that I need Authorization to use email server ! never had this happen before and I don't know how to overcome it and get my EMAILS SENT. CAN YOU PLEASE HELP.

When importing logins and notes and URL from Chrome to Firefox, why the latter doesn't bring notes and read double URLs?

All of my notes are gone and if similar URLs are doubled.

Sharing one screenshot, since I cannot share another due to privacy (until a Mozilla dev team asks for it directly without sharing it on public platform).

After a web search via the top toolbar, when the keyboard is minimized the area behind the keyboard is not rendered. At this point, if I open the menu and bookmark the page, the "Saved in Bookmarks" message pops up at the bottom of the page, and then the area behind the keyboard is rendered. After that, the keyboard and the area behind it works fine, when the keyboard shows and hides. If I open a new tab and do a web search there, the same thing happens ie no render behind keyboard. If I go back to the previous tab, it also re-acquires the problem.

If I touch and hold (for the copy-paste context menu) when the problem occurs, the un-rendered area renders instantly.

If, when the keyboard is visible, I press and hold for the context menu and choose "select all" and then minimize the keyboard, the area is not rendered. If at that point I tap anywhere to clear the selection, the selection clears and the keyboard reappears. If I then minimize the keyboard, the area behind it is rendered correctly.

That doesn't happen with other browsers. It happens with default and other keyboards. I've been using Firefox since I got the phone (Samsung S9+) and this just started happening a week ago. I am on android 10.

This is probably device, UI and Android version specific. Just throwing it there in case someone gets an idea. Thanks

I signed in to be sure to save my bookmarks and i lost them instead. When i hit sync, i wanted to backup my current bookmarks. Instead, I lost them. It reverted to the old bookmarks i had a few weeks ago. I lost all of my bookmarks from the last few weeks. HELP!

I am just a non-computer-literate old woman. I have tried to follow advice from the community forum. All that SMTP stuff is Greek to me. Since the last update to Thunderbird, I can't reach my daughter or my neighbour. One uses Hotmail and the other Yahoo. sometimes after about 4 days my neighbour will tell me he finally got a message.

Please change this. The only way I can reach them is to leave Thunderbird for webmail. It's a nuisance. Can someone please advise.

Paypal hangs when transferred from vendor site to complete purchase. Relaunching Firefox in troubleshooting mode resolves issue. Also works with Safari. What's wrong, what needs to be changed?

This happens in all my email accounts, I have pop downloading all files from the server & imap on other accounts.

I don't know where to add shortcuts all at once instead of adding each one individually, I tried to search for a "shortcut folder" within the bookmarks manager and i found nothing, is there anything I can do to move opera browser's speed dial bookmarks into firefox shortcut
