I updated to version 133 today and was confronted with the vertical tab bar. I did not ask for this or want it, and now I can't get rid of the side bar, in fact I seem to have just made it worse / wider. How can I get rid of this (and block it) It is just taling up space on my screen. Please help.

Am I the only one that finds it almost impossible to change fonts. I can change what I type to Large. But that's all. I can't change anything I Cntrl-V into a message. Or inherit text in the process of a reply.

I don't like threaded conversations view. I turned it off so my inbox doesn't show it any more, but search results do and I find it impossible to find what I need. Is it possible to turn off ALL of those threading features across the entire program? Thanks

Hello,

Recently I opened Thunderbird and it automatically added the following folders to my account:

https://www.imagebam.com/view/MEX6LYC

All the generic yellow folders below the Deleted trash can icon suddenly appeared and they weren't there or weren't shown before. I right-mouse clicked on the account folder, went to Subscribe, unticked the folders that I don't want to subscribe to (all the yellow ones were there), restarted Thunderbird and they all still appeared and the boxes I unchecked, had just rechecked themselves.

I don't want them shown. Is there anyway to fix this?

Thanks

My page throws errors in Firefox Nightly such as

Expected color but found ‘undefined’. Error in parsing value for ‘background-color’. Declaration dropped. preview.htm:1:1

and

Expected color but found ‘undefined’. Error in parsing value for ‘color’. Declaration dropped. preview.htm:1:1

The page references ten CSS files besides having dozens of its own CSS declarations. The issue is tha the reference provided to the error (:1:1) does not indicate where I can find the error. That is, I don't know which declaration is at fault. Is there some straighforward way to find the declaration in question?

My Quick Filter Bar has been disappearing for years. I add it back by selecting View-Tools-Quick Filter Bar but eventually it will disappear again. It will remain a few weeks or so and then it will be gone. I don't know the behavior that causes it to disappear. My only guess is that I coincidentally hit some sequence of keys that de-selects the option. Any ideas on how I can prevent this? I have version 52.5.2 (64-bit) but it has occurred for many, many versions. I would very roughly guess it has been occurring for over 6 years.

Thanks, Mike

I haven't upgraded browser versions for a while and I'm now going from 109 to 132. Pretty bad I know.

I'm having a number of issues but for this post I'd like to concentrate on userChrome.css.

In version 109, I had a custom font for the top menu bar, the top menus, the bookmark toolbar, the bookmark toolbar menus, and the right click menus. I did this by including the following in userChrome.css (as per [https://support.mozilla.org/si/questi.../1335097|here]:

1. navigator-toolbox { font-family:"MyFont" !important }

This worked great, but it is no longer working in version 132. Obviously I don't know in which Firefox version this stopped working.

Has this been disabled by Mozilla or has it been changed? If it's been changed, how can I achieve it now?

I'm very grateful for any help!

Made a mistake by changing user_pref("layout.css.devPixelsPerPx" from I think - 0.5 to +0.5 as incoming emails font was miniscule, but made nor difference... so thought it may be a font size, so changed to 12.... Now ginormous and unreadable. Searched through pages here for an answer and got to the prefs.js folder to find this file but it is not there.... I searched with notepad edit search for "layout" but no luck. Any ideas anyone? I tried adding the line user_pref("layout.css.devPixelsPerPx", "1.5"); whilst TB was closed and then opened TB but had made no difference.. :-( Any ideas anyone? TIA Graham

Using Tbird 78.14.0 (64 bit) with Windows 10. I can no longer access the Page Setup screen properly. I suspect it's because I accidentally put a very big value in for the top margin. The print preview for even a short email says it's many pages, there's no text visible on any of those pages, the only part of the Page Setup screen visible is OK and Cancel at the bottom, and I can't get to the top of the screen. I've tried closing and re-opening Tbird to no avail. How can I get to the top of the Page Setup screen to fix the problem?

All of a sudden, I can't see emails that I know are there because the subject of a previous message in my inbox is underlined. I can find the emails when I search for them by putting in a recipients name. And when they show up the thread column exhibits a red flag (don't know what it means). HELP.

Before the last update, when you assigned a colored label to the message (e.g., work, important, etc.), the entire title, header of the message, took the chosen color. Now you only see a small tag.

'The previous system was definitely more practical. Can it be reactivated?

The fucking forced dark mode has return despite the previous fix layout.css.prefers-color-scheme.content-override = 1 in about:config fixing it for years. This and the current replacement fixes don't save. I want a solution for PERMANENT light mode (black text on white background) for ALL menus, pop-ups, dropdown menus and hover over tab info.

And don't tell me to go search for a different theme I've already spent hours doing that and firefox has broken them only making some menus use the appropriate mode. On top of that I can't even pick an option to search for one that uses light mode I just have to go through each one and try it if I want to know which mode it uses that is NOT a solution to anything.

Replacement "fixes" for reference: ui.systemUsesDarkTheme won't even let me set to 0 only has true/false browser.theme.content-theme set to 1 browser.theme.toolbar-theme set to 1 (Why in the absolute hell these were added when a simple addition to preference setting wasn't is beyond me)

Very sorry for the aggressiveness but I am so very VERY tired of having to fight firefox on this preferance for years when their dark mode hurts my eyes.

One of the things I heavily rely on with FireFox is it storing words I type in reply boxes on various forums. Lately however, Firefox only seems to keep them for several hours, then they disappear. For example, I can type in "K Frame." (See image attached) The next time I go to use that field again, that text will automatically appear. And it may continue to do so for several hours, even if I close out Firefox and return later, but eventually, within 24 hours, it will disappear and I will have to retype it again the nest time I want to use that phrase. FireFox used to hold these words or phrases forever.

Any suggestions????? Both my Windows 11 and Firefox are up to date.

I continually receive this request for access to an account that is not one I have added to Thunderbird. How can I delete this email account and stop these annoying repetitive notices???

Hallo und guten Tag,

ich habe für Windows [PC] und Android [Pixel 8pro] jeweils die beiden aktuellsten Versionen von 'Thunderbird x64'und 'Thunderbird: Free Your Inbox' installiert und eingerichtet. Es sind zwei E-Mail-Konten mit jeweils einer Alias-Adresse eingerichtet, alles unter GMX.NET , IMAP+SMTP sind ebenfalls aktiviert [IMAP port993 und SMTP port465]. Leider bekomme ich es nicht so eingerichtet, daß Mails wenn sie am PC oder am Pixel empfangen und verschoben oder gelöscht oder als Spam markiert sind, daß dieses dann auch am jeweils anderen Endgerät so erscheint. Es werden immer wieder alle Mails neu als eingegangene Nachrichten gezeigt und ich muß dann am jeweils anderen Endgerät die gleichen Aktionen vornehmen.

Wo liegt der Fehler, was muß ich tun um das Problem zu beheben.

Hi, I download some e-mails. After checking the emails, I want all of them to be deleted from thunderbird but... ...I want only specified emails deleted from server.

In Mac's "Mail" program, there was a special window, where I could see all e-mails on server and just select which I want to remove from server.

In old Outlook, I've used "Rules". There I could set the parameters for specified e-mails and then tell outlook to "leave that message on server" or "Don't download that message from server".

How to do it in Thunderbird?

New PC and so installing Thunderbird again. Want to set up a sound alert for new messages, but there doesn't seem to be any sound files at all, default or otherwise. I tried putting Tonequilla in, but that doesn't seem to work with this latest version of Thunderbird which is a shame as it's really useful for me to have an alert since I moderate a forum.

My husband's Windows computer failed, and I am setting up his new Chromebook as a holiday gift.

Unfortunately, the instructions for setting Private Mode as the default for Firefox don't fit what I see on the Acer Chromebook 315.

Please provide appropriate instructions. I want to place it in his office, ready to go, before he gets up tomorrow morning, December 25. I am in Central Time in the US.
