Today (06/12/2025) upon opening a new tab, Firefox slid the new option of uploading a custom picture to apply to the background. Tried the new feature, now I can not find the setting that allows me to change the picture. I read the thread "Customize your wallpapers". The instructions are as follows; You can personalize your Firefox New Tab page by adding one of the available wallpapers. Follow these steps:

  1. In the right corner of the New Tab page, click the gear IG settings icon.
  2. In the customization panel, under the Wallpapers section, you will see different categories like Solid colors, Abstract and Photographs.

       Click the category you prefer. For example, selecting Abstract will show a variety of abstract designs. 

The problem I have is the customization panel is no where to be seen, I have click on EVERYTHING possible, it is not in my settings, why? How do find this?

I'm looking for solution to make or prevent Thunderbird automatically filling up the "From" box.

In other words; I want the "From" section to be empty every single time for me to fill up. Just like I have to do with the "Subject" and "to" boxes.

I'm willing to hack Thunderbird if there's no an user friendly solution for this I want! Just please tell me what to do and I'll do!

Thank you in advance, Attila.

I am having some trouble getting Thunderbird to display all my messages. I tried troubleshooting mode and found that all the messages were displayed. Restarting in normal mode having disabled my extensions and hardware acceleration, the problem returned and I could not see most of my messages. So I need to make the other changes that troubleshooting mode makes. These are described at https://support.mozilla.org/en-US/kb/troubleshoot-mode-thunderbird as

• Window and sidebar size and position settings (described in terms of Firefox)
• userChrome and userContent customizations ; see userChrome.css and .js and userContent are unsupported

I do not understand what these are and how I can set them for routine use. Can someone point me to an explanation? Thanks.

I can't seem to get the search message window to shrink down with the right click commands, nor with the arrows at the edges of the window, this has been going on since the beginning of 128 . . .

How to disable the Enterprise Roots preference-have tried everything I can find on this issue. In summary, deleting certificate via reg edit but this does not work, have to delete certificate every time I re start windows 11 desk top pc.

Any other advice? Thanks

Version 128.11.esr I see no way to move the menu back to the top which is where Windows OS/2 Linux and many other OS put it There are links saying going to setting and use Search Type Legacy but I cannot see any option like that in the latest settings.

As Someone who has an award for 508 Compliance, that is the US Federal requirement for accessibility to software. You should always keep it simple. The menu should always be at the top because that is what people use to decide to do.

The younger generation think a search bar is the starting point for finding things. You do not remember the desktop environment I grew up and still live in successfully today.

The main advantage if living on a desktop today is that is free of charge and I do not need to revise my hardware every 10 years let alone every couple of years because it still works and it is secure.

I have arranged my life so I do not have to move to dramatically reduce my carbon foot print. If you accept that environment desktops rule OK.

Also only having emails or events or tasks planning or finance on the screen gives you way more room to read things. I use two monitors because I have a lot to read. I choose what I want from a menu.

I use a search bar once I am on the right window

There should at least be an option to have the menu at the top.

It is the sort of decision that could loose you customers because it makes your product harder to use for those of us who grew up in a desktop environment not on a Web Page. And people who have to work in the US Federal Government.

In my web browser I always have the menu visible and at the top. Then the tabs then the URI editor The search bar is the third line down not at the top. Followed by the bookmarks toolbar then the web page.

Having the same format in every product would makes your products consistent and easier to transition between.

In the latest version of Thunderbird things have moved around for what to me seems zero benefit.

I would repeat an old maxim that has made me one of the more efficient programmers. If it ain't broke don't fix it.

I am efficient because I spend most of my working out what not to change because it works. So actual hardly do anything.

One reason banks liked OS/2, was because it never needed rebooting. One bank had an OS/2 server running continuously for 10 years. When it eventually did break they had trouble finding it because no one had touched it for 10 years.

Enough ranting, thank you for what is otherwise a great product. Just be open to the fact that some of your customers would be happier if you just applied security updates and left the UI exactly the same as it was for the rest of time.

Having written utilities for Citrix Systems Inc. that ran exactly the same business logic running on 8 OS. It would be nice to have the same level of consistency in Thunderbird.

The issue with that goal is you structured your menus differently on Linux than Windows, so making things completely consistent would cause some unavoidable movement of items in the menu.

I have used Thunderbird for years (now on 128.5.2esr (64-bit) for Mac). I have a very large number of folders, and I would like to have a default setting for columns in new folders I create. I am aware that you can change the column setting in the folder by clicking the "Select columns to display" button and selecting the ones you want, and that you can change the setting for all folders in an account by going to the "Apply columns to..." > "Folder and its children..." > select the account > select the account name at the top of the list. But I would rather not have to do that every time I create a new folder, but I can't find any other way to do it anywhere, including on another answer to a question in this forum, https://support.mozilla.org/en-US/questions/1426413.

Then I found two settings in the Config Editor... that seem like they might be where this can be done:

• mailnews.database.global.views.conversation.columns, whose settings in my case are:

{"selectCol":{"visible":false,"ordinal":"1"}, "threadCol":{"visible":true,"ordinal":"3"}, "flaggedCol":{"visible":true,"ordinal":"5"}, "attachmentCol":{"visible":false,"ordinal":"7"}, "subjectCol":{"visible":true,"ordinal":"15"}, "unreadButtonColHeader":{"visible":false,"ordinal":"9"}, "senderCol":{"visible":false,"ordinal":"17"}, "recipientCol":{"visible":false,"ordinal":"19"}, "correspondentCol":{"visible":true,"ordinal":"21"}, "junkStatusCol":{"visible":false,"ordinal":"11"}, "receivedCol":{"visible":false,"ordinal":"23"}, "dateCol":{"visible":true,"ordinal":"25"}, "statusCol":{"visible":false,"ordinal":"27"}, "sizeCol":{"visible":false,"ordinal":"29"}, "tagsCol":{"visible":false,"ordinal":"31"}, "accountCol":{"visible":false,"ordinal":"33"}, "priorityCol":{"visible":false,"ordinal":"35"}, "unreadCol":{"visible":false,"ordinal":"37"}, "totalCol":{"visible":false,"ordinal":"39"}, "locationCol":{"visible":true,"ordinal":"41"}, "idCol":{"visible":false,"ordinal":"43"}, "deleteCol":{"visible":false,"ordinal":"13"}, "xnoteCol":{"visible":false,"ordinal":"1"}}

and

• mailnews.database.global.views.global.columns, whose settings in my case are:

{"selectCol":{"visible":false,"ordinal":0}, "threadCol":{"visible":true,"ordinal":0}, "flaggedCol":{"visible":true,"ordinal":0}, "attachmentCol":{"visible":false,"ordinal":0}, "subjectCol":{"visible":true,"ordinal":0}, "unreadButtonColHeader":{"visible":false,"ordinal":0}, "senderCol":{"visible":true,"ordinal":0}, "recipientCol":{"visible":true,"ordinal":0}, "correspondentCol":{"visible":false,"ordinal":0}, "junkStatusCol":{"visible":false,"ordinal":0}, "dateCol":{"visible":true,"ordinal":0}, "receivedCol":{"visible":false,"ordinal":0}, "statusCol":{"visible":false,"ordinal":0}, "sizeCol":{"visible":false,"ordinal":0}, "tagsCol":{"visible":false,"ordinal":0}, "accountCol":{"visible":false,"ordinal":0}, "priorityCol":{"visible":false,"ordinal":0}, "unreadCol":{"visible":false,"ordinal":0}, "totalCol":{"visible":false,"ordinal":0}, "locationCol":{"visible":true,"ordinal":0}, "idCol":{"visible":false,"ordinal":0}, "deleteCol":{"visible":false,"ordinal":0}}

The first one matches the columns I see in a newly created folder better, having the "xnoteCol" entry, but my new folders also have several columns related to my CardBook extension at the bottom of the list. Moreover, the settings' arguments don't make sense in terms of what I see. For example, I see the Thread column, whose settings – ("threadCol":{"visible":true,"ordinal":"3"} – make sense since "visible" is set to "true", but I also see the Attachments column, whose settings – "attachmentCol":{"visible":false,"ordinal":"7"} – *don't* make sense because "visible" is set to "false". Similar no-sense settings occur in the second setting.

So there *is* a way to change the default column settings in Config Editor..., which makes a whole lot of sense, but the way the settings are set in these two settings, which apparently are not the ones that fully determine my default settings given the CardBook-related columns that I see, do *not* seem to make sense.

The "Folder and its children..." approach works, but it makes it harder than it should be, and it seems like there must be a way to change the defaults in Config Editor.... If there is, please tell me how.

Thanks for any help you can give...

About a week and a half ago I experienced an issue with Thunderbird going through file folders and 'randomly' selecting emails to move to the 'Trash' file. At present I have over 1200 messages in 'Trash' with no common denominator for why they were selected. I've never changed my preferences for when or what to delete so it came as a surprise to see this many emails sitting waiting to be manually deleted by me. I'm convinced that the issue must be something in the 'prefs.js' file.

Running TB version: 128.11.0 esr (64-bit) Is the issue tied to version 128.11.0 perhaps?

I have four other TB email client accounts that all work perfectly, except for this one lame duck that really is getting out of hand.

Could probably import and edit the old 'prefs.js' file from a backup of the old email profile, but the number of changes would be significant. File size of the old 'prefs.js' is about 17 Kb's while the newly created one (four days ago) is only 13 Kb's

This client email account is / was very old and has been on the TB update schedule for years. The email address contains upwards of 11,000 emails on the server. There is no server space issue either. The email address is probably more than 10 years old. The other four client email accounts I have are much smaller and less than 4 years old.

Thinking that something in this particular client profile must have gotten clobbered by unknown means, I finally decided to delete the account and set up a new one (losing my address book in the process of course). Fortunately I found an 'abook' in my backups that came close to being up to date.

Now, the new profile has these quirky issues where it won't open the inbox in a window showing the header information that allows one click to open the message immediately below.

Further, the new TB client is constantly downloading and updating folders with old emails from the server each time TB launches, and of course, it adds a few more emails to the 'Trash' file each time. Started at about 700 messages before I decided to delete the client profile and rebuild and now surpasses 1200 in just the last 4 days.

Running out of patience and options.

I recently installed 128.10.2esr (64-bit) on a Win11 computer. There's no option under "View, Toolbars" for it. Was it removed in this version or am I missing something?

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.

When the add-on "Copy Sent to Current" is running, the Composition Toolbar in the Compose Window is blank and therefore there is no "Send" button. What am I missing?

I've attached two screenshots - one with Copy Sent to Current disabled and the other with the add-on enabled.

I recently changed the sorting of my e-mails to be threaded by chain. I like to have all of my most recent e-mails show up at the top, but, within each thread, the most recent e-mail shows at the bottom (see the supposedly-attached image). Is there a way to flip this?

Thank you in advance.

The version I was using before could put have a layout like this with a simple tweak below: - Accounts - Individual email pane - Message list

I just CANNOT use Thunderbird if I can't do this. How do I do this in Nebula or what version can I revert to? Go to profile folder: Chrome folder userChrome css file Add this: /* puts message page in the middle */

1. threadPaneBox {-moz-box-direction: reverse !important;}

After the 139.0 update, I noticed 'Firefox Labs' is missing on my settings page. I checked the config and saw: browser.preferences.experimental true

I have telemetry checked Send technical and interaction data to Mozilla This helps us improve Firefox features, performance, and stability. Learn more

Once in a while the 'Firefox Labs' will appear momentarily then disappear.

Any ideas son why this is happening?

I just upgraded to Thurderbird V. 139, and my inbox looks completely different, which must have been part of this release intentionally, with every message summary now in an outlined rounded rect box, rather than beiung presented as a simple one line of table. Is there a way to go back to the old look? It let me see way more message summaries at one time, even when the new look is on high density. Thanks!

Hello all,  ;-) I just upgraded from TB 138.0 to 139.0. The message display style changed from a simple compact list to something still called "compact view" but is a far cry from being compact (see adjoined pix). How can I recover the former list display of messages I had with Thunderbird 138.0 ? Tx.

I am so frustrated with Thunderbird I'm about to give up and find another app. I had to reload Windows 11 on my computer and before I started I saved all the Thunderbird info as instructed by support. Now that I am back up and running I'm trying to get Thunderbird back. When I down load a new version of Thunderbird it sees that I did have an account in the past and wants to use that info again. I get to a page where I have to put my full name in, then my email address and then a password. The only password I can find in my password folder(real paper) I can only find a Firefox password. I put that in and continue. It recognizes the password and shows me the info it wants to use for my account. I click on "done" and it starts looking for a password again. After a long search it comes back with a yellow box and says "its unable to log in at server. Probably wrong configuration, user name or password." I've tried changing the Primary password but get no results, not able to. Tried uninstalling and running the version I have stored from before the Windows reinstall and I always end up in the same place......I've been banging my head against the wall on this for several days now and am ready to use Microsofts software instead...... Any ideas before I delete and give up on Thunderbird???
