I am using the latest version of Thunderbird 128.3.3esr 64-bit on my Windows 11 Laptop.

I have just discovered to my dismay that I am no longer sending Return Receipts to my received emails. I know that in the past that I always did! My Global Settings for Return Receipts have not changed. Any suggestions or advice would be much appreciated.

Messages I send do not show up in Sent folder in Thunderbird on Windows 10.

The emails do arrive to their destination email but do not show in Sent folder.

Is this a bug or is there a setting that needs to be changed to fix this?

I can no longer log in to Facebook without this type of message popping up: "Your request could not be processed." These messages do not look like they come from Facebook. When I "X" out of the messages, the page looks fine, but I'm not taking chances to log in with this sketchy situation. I have deleted cookies, etc. multiple times, even though I have Firefox set to delete cookies upon closing.

No problems on my other browser...except that I don't want to use that browser. I want to use Firefox with Facebook like I have for almost a decade.

Master Password not working. When I go to passwords, screen is fuzzy and I'm not able to log in. I can see on the fuzzy screen "no saved passwords" but the screen is not functioning.

I was having issues with the app for my mail.com account so my thought was to delete it and then reinstall it Just prior to doing that I wasn't sure if I remembered my password or not because I never log out of the app anyway I went to forget password and put in the info and it said it sent an email to an old phone number that I used to have and I don't have access to anymore. I've sent three emails to support at mail.com to no avail so I went to Google passwords to see if there was anything in there, there wasn't. So I was playing around looking to see if I could figure it out and turned off the synchronization and it logged me out up until then I had access emailed support again again still haven't got a response then I remembered Firefox Mozilla had some sort of password thing I just had to find it maybe it would be in there so I ran across this website of mozilla's logged in and it had my Yahoo account as a primary and my mail.com as a secondary I'm not sure how all this works and I'm not sure if I did the right thing or not but I was able to reverse them make mail.com The primary and my Yahoo the secondary I'm not sure how to use this thing as I'm not all that savvy on this kind of thing anybody any help would be appreciated, thank you, Scott Stone

Recently, the Firefox browser stopped working. Specifically for me, Costco's website, and Aetna. I believe the issue could be that those websites require that the location is confirmed, but no pop is generated, thus causing the website to not work with Firefox. Please help me, as your browser is the best.

Bookmarks dropdown menu opens up halfway down and it's not possible to scroll back up to the top and add a bookmark. At first I thought it was a mouse problem - changed mouse - problem remains.
