A friendly hello to whomever is kind enough to read this! Your help is greatly appreciated!

The latest update caused an edit I made to my Profile's userChrome.css file to be nullified. Now there's huge bar where the tabs toolbar used to be, and apparently it's not the title bar, as when I activate the title bar in "Customize Toolbar," this huge gets replaced by the actual toolbar.

I've attached my css code below for inspection. It used to work perfectly, but after the last update (133.0) it's no longer working. What can I do to fix this and have it like I had it prior to the latest update (133.0)?

userChrome.css File: `#main-window[tabsintitlebar="true"]:not([extradragspace="true"]) #TabsToolbar > .toolbar-items {

 opacity: 0;
 pointer-events: none;

}

1. main-window:not([tabsintitlebar="true"]) #TabsToolbar {

   visibility: collapse !important;

}

1. main-window[tabsintitlebar="true"]:not([extradragspace="true"]) #TabsToolbar .titlebar-spacer {

       border-inline-end: none;

}

/* Adding empty space for buttons */

1. nav-bar {

margin-right:140px; }

/* 15px for dragging whole window by mouse*/

1. titlebar {

appearance: none !important; height: 15px; }

/* Fix for main menu calling by Alt button */

1. titlebar > #toolbar-menubar {

margin-top: 10px; }

/* Move minimize/restore/close buttons to empty space */

1. TabsToolbar > .titlebar-buttonbox-container {

display: block; position: absolute; top: 17px; right: 1px; }

1. sidebar-box {

 min-width: 250px !important;

}`

Hello, I am running Firefox on a W10-Pro PC. I always click the lock to check certificate validation. In the last month I keep seeing "Connection verified by a certificate issuer that is not recognized by Mozilla".

When I click for more information I see that "Norton Web/Mail Shield" does not recognize the certificate issuer. When I click on Learn More it takes me to a Firefox site "How to disable the Enterprise Roots preference" I also checked W10 certmgr.msc and I see Norton is listed. Images included below. I would love to resolve this issue. Thank you for your time.

Be descriptive. Saying “playing video on YouTube is always choppy” will help us understand the issue better than saying “something is wrong” or “the app is broken”.

Hi,

I'm on OS Windows 11 and the latest version of FF (133). I also use NordVPN; I can access the web via Edge and Chrome with VPN, but for the last month, it doesn't work with FF. What could be the problem?

When is Firefox (across devices) going to bring "Tab Groups" in-built in 2025 as it is difficult to ditch Chrome esp., if it is related to work or research and similar tabs are opened up?

I have to rely on chrome and edge for same and both have not only brought it but improved it considerably. Also, chrome has not brought for mobile devices so grouping of tabs is more easy and simple but when I look at Firefox and Firefox based browsers, I see nothing of that thing present. The addon esp., Simple Tab Groups (https://addons.mozilla.org/en-CA/firefox/addon/simple-tab-groups/) is unreliable (see reviews).

If Firefox want us to use their browser and as default, they should see why we are using Chrome and Edge (latter, having vertical tabs in-built, also).

I hope 2025 is a year Firefox learns of how to retain users across devices. Currently Firefox is more from 2005.

Browser Choice Alliance wont be helpful if browsers like Firefox dont see users and their reviews and posts and issues reported. "https://browserchoicealliance.org/"

3 years post and still no work, and Firefox wants us to use their browser over Chrome and Edge. Why? And how?

On my wife's computer is a IMAP Email account. Cox moved our servers to Yahoo. Since then filter rules are set in Thunderbird, but they don't work on her computer. I have tried setting filter rules to work before or after determining as junk and deleting those listed in filter rules. I would prefer to see all junk deleted at the server level before reaching her computer, but that's not an option like it was with Cox Email. This works OK in my POP account, but on her IMAP account it creates a second JUNK subfolder under TRASH and lists all the spam that agrees with my filter rules. Nothing gets deleted. The filter rules have been changed to filter the JUNK folder instead of the INBOX and delete those files, but that doesn't happen! I have to move all the spam in the JUNK subfolder to the regular JUNK folder, then run each set of filter rules individually to move into trash. I can then delete the JUNK subfolder but it is automatically recreated.

I know we must use EITHER Filter Rules or Spam Assassin, but not both. I want to get rid of Spam Assassin because it looks like it's creating the problem, but I see no way to do that. Unchecking Spam Assassin in filter rules does nothing. In any case, I need a solution. Jim

I have a domain for a business and web hosting. Email accounts come with the hosting and I set up several. At some point, I began to get pop-ups asking for my logon credentials. Although they were annoying, I put up with them for a time. I thought a password problem might be causing it, so I changed the password and made sure it was the same both on the server and in Thunderbird. Eventually, this situation became more than a nuisance and (after saving the messages off-line) I deleted the email account from both Thunderbird and the server. This did not work and I still gat the pop-up messages! I have consulted with the web hosting support staff and they assure me that the account is no longer on the server. Obviously, there is some vestige of the deleted account in Thunderbird someplace and it is causing the program to attempt to sign in to the server to access the no longer existing account. This, in turn, causes the server to request the credentials for the deleted account, resulting in the pop-up messages. How do I get rid of this?

in TB 128.5.0esr catchall identities - *@domain.org - don't seem to work anymore. Well...

I regularly receive email at my catchall address: "Kordin <your-business-name@mydomain.com>"

But my mail host won't let me send from a custom @mydomain.com without setting it up, which is too much hassle.

So I spent a bunch of time a while ago setting up a different mail provider to send from these custom addresses, while still using my primary provider just for my most important addresses.

TB used to use the identity with a specific match for a from address to reply from. Otherwise it would match the *@mydomain.com identity and reply from "What You Called Me <what.address.you.used@mydomain.com>"

Currently it seems to select the wild card identity, but not populate the name. It also no longer displays the warning message that it will use an alternative identity.

I feel sure there's been some regression here, but the TB docco is all over the place.

Can someone please shed some light on this for me?

All relevant links gratefully received.

TB 128.4.3esr on macOS and 102.15.1 on Win10/64.

If I click Save on an attachment to a message, TB dutifully opens a Save dialog box in the folder/directory that I've specified in Settings > Files & Attachments > Save Files To:

No problem there.

But if I double-click on an attachment to open it directly into an application such as Excel, Word, etc., the attachment gets saved and then opened from some mystery folder such as:

<myHDD>/private/var/folders/pd/zw70ypv94xgctzszqtp3fxwr0000gp/T/pid-91611/

on macOS or:

C:\Users\<MyUserName>\AppData\Local\Temp\pid-1568\

on Win10.

Many years ago I remember that attachments were always saved to the Save Files To directory, but that changed some time ago.

Is there a way to change the behavior back, so that attachments always save to Save Files To, regardless of whether they're explicitly Saved from the message or double-clicked/opened from the message?

Thanks!

Hi!

Thunderbird emails stopped 9/11/24. Sadly, I cannot send or receive emails via Thunderbird. When I open Thunderbird on my Mac (2010) updated to version 10.12.6. I receive a message box noting 'Login to account "dolsen00@msn.com" failed'. Log in to server pop-mail.outlook.com with username dolsen00@msn.com failed.

Choices are ENTER new password Cancel Retry

I am not familiar with pop-mail or outlook. I've read through a number of articles hoping to find a solution. I've searched through historical emails from Microsoft to see if I might have mistaken for trash an important change, to no avail.

My current workaround for email is via my iphone or logging into msn.com on my Mac. I miss many of the features Thunderbird offered!

Thank you for your help! Donna O.

I know the blue circled number is the unread emails in the folder.

What are the black and grey circled numbers?

Is there an encyclopedia or user manual for Thunderbird?

The Thunderbird for Android app on my Moto G 5G has a problem with Gmail. For some unknown reason I am receiving several authentification failed notifications per day sometimes 3 or 4 in a row. I uninstalled the app for now in hopes that maybe someone has an answer to this problem. I have Hotmail, and Yahoo mail also on the app without any problems at all, I followed all of the instructions given when I downloaded the app.

Since updating Firefox I can no longer connect to known good sites without getting "Did Not Connect: Potential Security Issue". This includes U.S. government sites! For instance, try connecting to https://covidtests.gov/ for example. What is going on?

Hello,

I have every about:config and settings option set to recommended to prevent autoplay videos. NONE work with yahoo. The vids will drop to the lower right hand corner but even if I click on the close window X they still pop open again. And again. And again. Is there a solution to this arrogant, self-centered behaviour by yahoo?
