I have downloaded Thunderbird from official Mozilla homepage. It seems to be installed correct. I got the icon and a question : should we start Thunderbird now. I answer yes. Then I get the message : Thunderbird is not found ? but I have just loaded it ? I am running windows 11 and I have got newest upgrade.

Hope you can help me out. Thx in advance. Regards Thorvald Antvorskov

PS I also have a PC running Linux Mint. Loading Thunderbird here was no problem.

I can't save my tabs & windows anymore, I have the box checked but after I close down the computer I lose all the tabs when I reopen and then I need to put them all back manually. What has gone wrong it always worked before for many years? Please tell me how to fix it

FF is offering up possible login names for a particular site I have used previously even though I have removed all related browsing history, form data, and cookies (and cleared the cache). What am I missing? Is it using stored history for unrelated sites to guess at a user name, or is there some other hidden history I need to clear?

My shortcuts keep disappearing from my home page when I turn my computer on. Sometimes it's fine, sometimes I have to spend a long time trying to find them. Sometimes I just have to restart Firefox. Sometimes I have to go into settings. Sometimes I can't work it out.

Has been happening for the past month or so.

I have issues with Firefox when I am accessing my Schwab account. I cannot access all the functionality of the site with Firefox. If I switch to Chrome or Edge the site works fine.

Good evening. I have had to install my FF after a system repair. I have everything set back except when I click on a link and hightlight an item with my mouse and right click it opens a new tab. But before where it would just open it changes to the new tab immediately. Under settings I have the 'when open new tab switch to it immediately' unchecked and I was directed to four settings on about:config including browser.tabs.loadDivertedInBackground to set to true. I did and the behavior did not change. Any suggestions would be helpful. Thank you.

I am working in Japanese but this site changes to English version and I cannot ask question in Japanese. So I do not know how English words are shown but I try to translate Japanese message to English. I have been using this Mozilla thunderbird for many years and have installed in several PC's. And now I bought a new PC Win 11. I downloaded software and message like that Account setting is found in Mozilla ISP data base. I proceeded as instructed and acknowledged warning. Then message is shown like this cannot logged in server, check if username, password or setting. I renewed password but still same message is shown. I would appreciate kind help.

I have left Shortcuts toggled on, since I want to see the 18 shortcuts that I have manually pinned. Fine so far.

I have unchecked Sponsored Shortcuts, but I still am seeing sponsored shortcuts. What am I doing wrong?

I tried importing my Outlook Classic address book. As you can see from the attachment, I really messed it up!. I am not technical at all, I wasn't sure if I needed to import my contacts or my address book. I think, but am not really sure, that I exported my .pst file, address book to a csv vile. Can anyone one straighten me out? If I have to start over, how do I delete the mess I created without loosing all of my other settings? Thank you very much 😊😊😊

Why does the mozilla not give my mobile the ability to synch the passwords? I mean it says that the camera used to sign in.lust be from the Firefox app itself but what is the firefox app if not the website on my mobile?

I suddenly can no longer get my Gmail to appear in my Firefox browser. (I CAN get to +use Google.com, but when I try to go to https://mail.google.com/mail/u/0/#inbox", I just get a blank white page.) I did not (to my knowledge) change any settings or have some strange thing happen. Please help!
