3 Days ago Thunderbird, Firefox and Windows 11 all updated at the same time. Now, every time I close and reopen Thunderbird, it takes me back to the "Setup your existing email" page, and I have to create a new profile and start over. I then restore my email and settings, etc. via a backup, only to have the same thing happen the next time I open Thunderbird. Firefox is being similarly affected, but not quite to the same degree. I don't lose my bookmarks, but all my settings have to be restored. I'm using Bitdefender Total Security, and have turned everything off, and the same thing happens. I've been using all these programs for years, and Windows 11 for over a year with no problems. Please help.

I pressed download but I don't know what to do next. I signed up for the newsletter and gave a donation. I don't know where to find the app or how to complete the installation. Thank you.

I have the updated version of Firefox but when I go to either Facebook or Instagram pages, I get a message saying "This version is no longer supported, please upgrade your browser." How can I fix this?

Please be advised that when I tried to download Thunderbird program using following URL, I got "404 Not Found" Error. URL has miss spelling "ja" should be "Ja-JP-mac". https://www.thunderbird.net/ja/download/

（Wrong） https://download-installer.cdn.mozilla.net/pub/thunderbird/releases/128.4.3esr/mac/ja/Thunderbird%20128.4.3esr.dmg

Good day!

I download 64 bit exe on win 10. I run it, it unpacks, asks for what user I want to run TB as, I pick one, program closes, I never see it again. Done it multiple times, nothing. App just silently refuses to install

I'm moving from iMac 12.7 to Mac-mini 15.1 and Thunderbird's old files cannot be imported. So, I deleted the failed Thunderbird app in the new Mac-mini and download a new Thunderbird to the Mac-mini. I made sure it's the desktop version with US English for Mac before hitting the download key. After downloading the Thunderbird 128.4.3esr.dmg and double-clicking the file and moving Thunderbird into the "Applications" directory. This last step seems to go on forever, that is, when I tried to eject the Thunderbird's download, it claim the download is NOT finished. What did I do wrong, and how to fix this problem?

Because my previous Thunderbird profile appears to be corrupted, I am trying to reconstruct it without too much duplication of effort. I have started with a virgin profile and added 3 mail accounts by way of the account wizard.

1. One of the accounts is an iCloud (Apple) account. Thunderbird offered to add my iCloud "Reminders" to Thunderbird's calendar, but the resulting entry shows a yellow triangle with an exclamation point, which seems to mean that it cannot be synced. The corresponding iCloud mail account appears to sync without problems. What must I do to enable the "Reminders"?
2. I also need to import the mail from the "Local Folders" in my old profile. Under "Tools - Import", it looks as though selecting "Mail Messages" will import all mail, which will likely result in hosing my profile again. How can I import *only* the mail folders form my old "Local Folders"?

I've been using Firefox for Android on multiple devices for many years now. I have poor eye sight and I end up zooming in on pages a lot, but when I do that the text doesn't auto-fit to the page so I end up having to scroll side to side as well as up and down constantly and it makes reading web pages a very frustrating chore. how do I get the text to auto-adjust to the new zoom level so it fits on the screen?
