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 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 😊😊😊

The https://support.mozilla.org/en-US/kb/thunderbird-and-yahoo article is ambiguous. Does mailnews.oauth.usePrivateBrowser only need to be set to true if you have 2 accounts from the (Yahoo, AOL, ATT) set? Or if you have any 2 accounts, including, for instance, 1 Yahoo! account and 1 Gmail account?

I had a Gmail address set up in Thunderbird on my old computer (Win 10). I had to get a new computer with Win 11. I have my Earthlink addresses set up okay.

But I've been unable to properly set up the Gmail address. I enter all the information, but the account vanishes from T-bird. All I have in Thunderbird is a Thunderbird Tab with Google info. It's a full page which might not come out clear with a screenshot, so I'm copying what's on this Tab ....

Google Account

BUT I don't see the gmail email account itself. It had been with the other accounts, but it's not there anymore. PLEASE give me step-by-step instructions so I can access this gmail account.

I've done what you suggested... it didn't work I installed an extension yesterday and it worked yesterday... Now today... not working even with extension

help please

I use Firefox for desktop in Windows, and I use Firefox on Android as well. I have enabled sync and signed into both browsers.

What I want to do is sort through the 50+ tabs that are open on my Android Firefox browser by opening them in my desktop Firefox session.

I am aware that I can open them one-by-one by following this how-to:

https://support.mozilla.org/en-US/kb/view-synced-tabs-other-devices

However, this is inconvenient: I want to open them *all* in one operation. This way, I can quickly bookmark them read them, and then confidently close all of my tabs in Android. (I have ADHD and this would help me a lot).

Is there an extension or option that would allow me to do that?

Please assist,

Gentili Signori, Sempre più spesso, quando si aprono le pagine di pagamento online, il browser non è più in grado di visualizzare correttamente la selezione dei metodi di pagamento o il layout complessivo della schermata di checkout. Questo sta diventando piuttosto frustrante, dato che sono un fedele utente di Firefox da molti anni. Tuttavia, questo problema mi sta spingendo a scegliere un browser che funzioni davvero, come Google Chrome, cosa che trovo piuttosto fastidiosa. Ci sono chiaramente aggiornamenti mancanti e lacune tecniche che stanno diventando sempre più profonde e evidenti, il che mi porta a credere che il vostro progetto non venga più aggiornato con la costanza che dovrebbe avere. Ciò è particolarmente preoccupante considerando che il vostro cliente più importante è proprio Google, che vi paga per rimanere in vita. Grazie.

Firefox won't load google or youtube. In my gmail spam folder I keep getting emails stating "payment declined cloud storage full".

Firefox not responding. I have tried everything on the Help pages. I have tried reset of everything. I have uninstalled and reinstalled from scratch. Still: when I open it: Firefox does not respond. And everything else also is very slow then. In Windows joblist I can see Firefox with 7-15 threads. One of them "not responding". I have no problems with Chrome nor Edge - W11, 16GB Ram

The recent update changed how the mute button works in Firefox, before it would replace the icon and would show text and whatnot if it was muted or wanted to autoplay; now it just always shows the mute/unmute button in a tab playing audio. This would normally be fine but it is causing my tabs to constantly be shrinking and expanding whenever the audio changes in a tab, and it's really frustrating me and it feels like an overall far worse user interface design than it was before, even if people were complaining about it. Is there some sort of middle ground where I can set a maximum tab size or something? I know this used to be a feature in about:config but it doesn't exist anymore for some reason. I've also tried using a userChrome CSS code for it that I found online; it got rid of the button but it still made the tab size change and the code I tried using for maximum tab size also didn't affect that. Really starting to frustrate me! Please give me any advice I feel like I've exhausted all my options lol

Hello. I have a question about Firefox. I shut down my PC and turned it on two hours later, but Firefox is still displaying page layouts properly, images on pages aren't displaying, and the screen remains blank even when I load a page from a bookmark. How can I fix this? This is the first time I've seen this happen, whether I've restarted or shut down and restarted.

Links keep opening in new windows, and not within new or same tab. Shift key is not stuck and all toggles in the Tabs Opening/Interaction Settings field have been turned off

I like to use picture-in-picture mode to watch a YouTube video in the corner of my screen while editing an image or playing an online game (since I like having something to keep my brain active while I'm doing something). Recently, however, this has resulted in my computer locking up. I don't really know how to describe it succinctly, but audio becomes super stuttery and it takes a second or more to render a single frame. Last night this resulted in the loss of an in-progress image (don't worry, I took photos of my screen so I could recreate the image), so I want to figure out how to stop this.

Just to cover my bases, here's my specs:

Device name LAPTOP-AI6N0TEJ Processor 12th Gen Intel(R) Core(TM) i3-1215U (1.20 GHz) Installed RAM 40.0 GB (39.7 GB usable) Device ID BDD80B46-B5E1-4B25-9FA0-3F833BD30C05 Product ID 00356-07436-33870-AAOEM System type 64-bit operating system, x64-based processor Pen and touch No pen or touch input is available for this display Edition Windows 11 Home Version 25H2 Installed on ‎11/‎7/‎2025 OS build 26200.7840 Serial number PF4RQKQJ Experience Windows Feature Experience Pack 1000.26100.291.0 Manufacturer Lenovo

I had a similar problem. The Spam settings were being picked up by my ISP from my mobile. When I looked at the Spam on my mobile, I could mark each individual email as "Not Spam". When I did this, the email appeared in the Inbox not only of my mobile but of my laptop too. A new test email went straight into Inbox of both devices and not into Spam of either.

I hope this helps.

I got a new computer, and after installing Thunderbird, it took forever to get it set up with the information from my old computer. Now, the unified folders aren't working. All of my mail is going into each account's inbox. There's no option to choose anything on the unified inbox, only the same thing as the other inboxes have. Help, please!
