When I use IMAP/SMTP incoming/outgoing servers, sending message fails: it asks me to enter another password, but does not give me a prompt to enter it. When I click retry it hangs indefinitely. However, if I create an account with Exchange/Office 365 account, sending mail works just fine. This problem occurs very recently, probably due to an automatic update to Thunderbird 140.4.0esr

Any clues and cues would be very welcome

I am using the new profile switching feature in the UI, from top of the hamburger menu. Firefox is my default browser on Windows.

Now, I want all links I activate from other Windows programs to open in a specific profile. I use the other profiles for auxilary tasks.

Is there any way to achieve this?

I suddenly this week cannot send email using Thunderbird (v. 140.4.0esr (64-bit)). I receive email fine. I can send email using webmail with my provider. Error message in Thunderbird is: "Sending of the message failed. An error occurred while sending mail: Outgoing server (SMTP) error. The server responded: resomta-h2p-555359.sys.comcast.net resomta-h2p-555359.sys.comcast.net ESMTP server not available (62240/216.183.125.238)." My provider says the issue is not at their end because my server settings are correct. Outgoing SMTP port is 465, connection security SSL/TLS. Operating Windows 11 v. 24H2.

For years, I have been routing all my Gmails through Thunderbird very seamlessly. Then my computer crashed.

Nothing on my hard drive was retrievable...so I had to download Thunderbird onto my new computer. I then proceeded to move all my Gmail to this newly downloaded Thunderbird. I had many different files in Thunderbird on my old computer, so everything was tidy and easy to find. When I opened Gmail after losing my old computer, I was relieved to see that the files, and the way I had them organized was the same. So, I assumed it would transfer over to the newly downloaded Thunderbird that way.

However, when I moved all my Gmails to the newly downloaded Thunderbird, all 3200+ Gmail emails were lumped into Thunderbird's "inbox".

What can I do to get everything back into their folders like they were before?

2 days ago you tube is suddenly blocked. 11/6/2025 i would click a video, it would "blink" at me and do nothing. i updated firefox, ublock was updated about a month ago and now i can't even get a home page to load. i have refreshed and restarted

I generally always use Firefox on my PC for everything.

I also often chat with Amazon as they are never short when it comes to fucking my orders

I have not used Amazon for the past 2-3 months and when I finally placed a new order 3 days ago, to resolve the usual non delivery issue, I contacted them via Live Chat, however instead of seeing Chat window pop open as usual, all I got was ABOUT:BLANK in new tab, hmmm...

So far to fix this or at least ascertain cause:

- I contacted Amazon.fr (where I live) and guy at digital services said, "nah, no flies on us, it's Mozilla's fault" - Edge, on same PC (windows 10), works OK for chat - Launching in safe mode changes nothing - Nor does disabling NordVPN - I also added Amazon.fr as "exception" in pop-ups, to no avail - and when I unchecked block box to enable all pop-ups, no better luck - lastly, on my iphone via Safari, all is good, assuming one enjoys typing with 1-2 fingers

my version of Firefox is up to date: 144.0.2

voilà

suggestions?

thanks

Hi - I have added Kagi as a search engine and set it to be the default. This works as expected, until at some point, hours later, for reasons I don’t understand, it switches itself back to DuckDuckGo. Kagi remains available as a choice, and I can re-reset it back to default. I’m not sure if this is a bug, or a misconfiguration on my part. Thanks.

Every once in a while, my pinned tabs and/or my tab groups disappear. this usually happens after an update, but not always. Sometimes I type a lot of commands, and FF seems to get upset and freezes or goes black. I restart and poof, they're gone. I made a screenshot of my standard pinned tabs so I can restore it from that, which is a nuisance in itself. But the tab groups are gone forever along with the urls I painstakingly researched. I read the answers to two previous queries along these lines, both of which gave extensive, tedious procedures to recover them. I'm not willing to go through all that just to use Firefox. I've switched my tab groups to Edge just to keep them safe and although I prefer not to be captured by Google or Microsoft, am thinking about just switching to either of them.

Over the last couple of updates, FF has seemed less and less stable. I tried the vertical tabs and liked them but the open sidebar on hover stopped working and when the sidebar itself got stuck on open it hid the history and AI sidebars. Plus FF was very slow to open. I reverted to horizontal tabs and now it's faster but still the pins and tab group problems persist.

I'm using it on an HP desktop in Windows 11. Sorry I don't have any screenshots.

Reader view doesn't work on many Lifehacker pages/articles. Can something be done to make it work on those pages? Here's an example:

Hello Firefox Community,

I’m facing an issue with my restaurant-related website Bojangles Menu with Prices—https://bojanglesmenuprices.us. .

When I search for my website in Firefox or share one of its pages through the browser (for example, by copying the link or sharing via email/social media), the preview doesn’t display correctly. Sometimes the image thumbnail is missing, and other times the meta title or description doesn’t appear.

Here’s what I’ve already tried:

Checked the Open Graph (OG) and meta tags on my site.

Cleared Firefox cache and cookies.

Verified that the site preview works fine on Chrome and Edge.

Updated all social and sharing metadata in my HTML.

Is there any Firefox-specific issue or setting that could affect how link previews or shared content are displayed? I’d really appreciate any help on how to make my Bojangles Menu website show up correctly when searched or shared via Firefox.

Thank you! Sonia

All right, so quickly, but from the beginning. I wanted to check if Mozilla is really as good as everyone says. I installed it on my phone. I'm mainly interested in browsing YouTube. I'll ignore the fact that all adverts and information sharing are enabled by default. How do I disable the display of short videos and posts that only appear on Mozilla and that I'm seeing for the first time? Is there such an option? Brave does not display posts on YouTube and there is an option to block the display of many elements on YouTube. No extensions need to be installed to block advertisements. So does Mozilla have any improvements over its competitors?

THE ABOVE ERROR MESSAGE HAS PREVENTED ME FROM ACCESSING 3 WEBSITES - PaddyPower, Ladbrokes, & UK National Lottery. None of the suggested remedies has had any effect. Can you fix it?

Hi, how can i disable background playback, when the browser is closed and the screen of the device is off? For example, when I'm watching a YouTube video, then I close the browser and turn of the screen of galaxy s10 ultra, the audio continues playing on the background while the browser is closed and the screen is off. I don't have the kind of problem with other browsers. I tried all of the settings, but didn't find anything in the settings thatt can disable the background audio. The only way to stop the background audio playing is by forced closing of browser or manually stopping the video playback on the YouTube video itself.

Thanks.

Every time I want to print an email, the default copy number on my printer menu is shown as 2.

I don't know how, when or why this change [from 1 copy to 2 copies] happened.

I wish to 'reset' the default copy number to 1, so I don't accidentally print a second copy and waste ink, etc.

When I want to print documents stored on my PC, the copy number field on the printer menu is blank, allowing me to enter the number of copies I want - so the issue appears to occur only when I print emails.

Hi everyone, I run a website, which provides information about mobile phone prices and SIM packages in Bangladesh. I’ve been working on improving page load speed using LiteSpeed Cache and Cloudflare CDN. While it works well in Chrome, I’ve noticed that Firefox doesn’t always cache pages or static assets (like images and CSS) as effectively. Does Firefox handle cache-control headers or service workers differently than other browsers? I’d also love any advice on best practices for implementing browser caching or service worker scripts that improve performance on Firefox without causing outdated content issues. Thanks for your time and any insights!
