I recently purchased a new laptop and needed to migrate my old Thunderbird profiles. This is what I did: 1. Backed up profiles from old laptop 2. downloaded and installed latest version of Thunderbird on new laptop 3. coped profiles into \roaming directory 4. tested and successfully received emails and viewed all old emails.

The problem is that the Mail toolbar is nowhere to be found. Also, the calendar is missing. I tried right clicking on empty space and it only showed "menu bar" as an option. Attachment shows nothing in the toolbars option of View dropdown.

Is Thunderbird ever going to fix the 'custom colours'? After the last major update, TB would not longer hold any custom colours. This is problematic because the colours offered are either too light or too dark to be read easily.

Sorry, posted recently and had then trouble finding out how to respond to help offered (jscher2000)! Noticed that the email version was "no-reply" so I didn't figure that would work! So, I tried to 'cut and paste' my reply (on a smartphone) and I ended up losing even the email reply text so here is a reconstruction. I tried the suggestions in order and the first one didn't have a "Restore previous session" option and the second one had "Recently closed windows" greyed out! And, when I entered "about.support" in the address bar (top rightish), I received a notice that I couldn't reach Google (Remember that I don't currently have internet access on my laptop). So, no joy there either! Can I not just change some current setting to prevent Firefox v 115.9lesr from saving the current 'Windows' and Tabs so that, when I again open Firefox, the previous session 'Windows' and Tabs would be used?!?

I have set toolkit.legacyUserProfileCustomizations.stylesheets to TRUE in both Thunderbird and Betterbird.

I have created the file C:\Users\MYNAME\AppData\Roaming\Thunderbird\Profiles\r2v9k1zw.default\chrome\userChrome.css

I have successfully entered css into that file that work as expected in Thunderbird v115.12 and has for the past several versions. But I have NOT been able to do anything in that file that works with BetterBird. In fact, using the inspector, I don't see userChrome.css even being loaded! I have also tried starting the file with '@namespace html url(“http://www.w3.org/1999/xhtml”)' but that makes no difference either.

How do I get BetterBird to recognize the userChrome.css file?

I tried redownloading Firefox after I saw that i was unable to download any extenstions/add-ons. Anytime i try to download something from the firefox browser, the download fails or gets cancelled. I never changed any settings, how can i fix this?

I understand the basic differences between unread folders and unified folders what I don't understand is why two of nine my accounts are listed in both unified folders and unread (see circled in red) how do I remove the two accounts from unified folders or

add more to it
and what makes it confusing is that the subfolders aren't the same when listed in unified or unread

Several upgrades ago, I created message filters in Thunderbird to forward emails received from specific senders to other email accounts that needed to get copies. While running version 115.12.1 32bit on Win 10, I had need to delete one of the filters. When I went to Menu Bar > Tools > Message Filters the Message Filters window does NOT show ANY filters regardless of which account (I have 20 and checked each) is selected. I have also searched my HDD, located all copies of msgFilterRules.dat and opened ones that might be related to the account in question. ALL of the msgFilterRules.dat files that I checked had only 2 lines.... version="9" and logging="no", except for the problem account where I had turned on logging and the .dat file showed "yes". I also went to yahoo and checked to see if I might have created the filter on the server side. However, according to yahoo, they discontinued the forwarding filter in 2021, so it's not happening there. I need to know how to find the forwarding filters and edit them.

Hello dear community,

I have a program that continuously monitors the download folder under Windows 11 for a specific file and retrieves it. I download this file in Firefox, but the said program gives an error.

I have noticed that when files are downloaded in FireFox, they already appear in the Downloads folder with the corresponding file extension with 0 bytes and these are then apparently swapped or merged with the .parts file.

The problem is that the mentioned program now tries to retrieve the unfinished file, which then leads to an error.

Does anyone know if it is possible to customize Firefox so that the file only appears in the download folder when the download is fully complete?

Many thanks for your help :D

I normally open messages in tabs under exactly one circumstance: when I right-click on a message and explicitly open it in a tab.

I've found that (until I changed the handling of PDFs to "Save file") any PDFs that opened using Thunderbird's preview function would reopen if I closed and relaunched Thunderbird. This is not desired behavior.

I will also note that if I open Settings, it opens in a tab, rather than a separate window. This is neither expected nor desired (and my natural reaction is to click the close button on the window, closing Thunderbird, because "Settings" is something I expect to be in a window, not a tab. And that, too, reopens if I reopen Thunderbird.

And worst of all, those tabs that shouldn't be reopening at all are reopening in front of the main tab.

There was an extension called "Thunderbird-DontRestoreTabs," that would do exactly what I want, but that was made obsolete when the underlying extension technology was deprecated, so it is of no use in 115.9.0.

Hail all:

OS: W11Ent_x64 V: 22h2 (b: 22621.3447) FF: 124.0.2 x_64 I tried several "Group Tabs" add-ons, like: Simple Tab Groups. Tab Group. And I few I can't even recall the name from. Yet, none works. Not ONE.

Now, I use Edge as well, on my corporate system that I got from work. Personal PC I use FF on.

But, the Edge Tab Grouping, which allows tabs to be "put to Eco-Sleep", while hidden the open tabs by clicking the Group-Tab Icon, is a feature I sorely miss in Firefox.

Odd, as, so many requested this feature, how come it has not been implemented over the many years of people asking?

Either way: Does anyone know a good, WORKING add-on that does the "Edge Thing" with FF tabs, please? Since, I often got like 200 tabs open, which is a real misery without Tab Grouping and "Hiding".

Thank you aforehand: Ke'Ylan.

When I view emails with photos attached inline (both in preview pane and fully opened) i can't see the images as they are massive and go way off the screen. Is there a setting to provide some kind of sensible default so the images are sized within the email i am looking at, so i can view them without downloading and opening in a photo viewer? thanks

Hi Thunderbird Community! This is my first post here.

I use TB 115 (currently it is up 115.10.2)

Whenever I receive an image as an attachment and I click on it and then comes opening abc image window. Since a couple of version back there is an image preview and the action buttons under them. In my case it is just trying to be. And I cannot change the window size, nor can I scroll in it.

Am I doing something wrong? Thanks Greg

Video in Firefox does not run .. no error messages .. nothing. It works fine in other browsers. When I click on the video .. nothing happens. It used to work but not now and I don't think I've changed anything.

Win11 Version 126.0.1 (64-bit)

Hi is there an add-on or can the settings of Thunderbird be changed so that when an email notification on macos comes through, it shows the first few words of an email. This is helpful for receiving verification codes. You can know it just by a glance at the notification rather than open the email.

At the moment it shows the email from and subject but not the first few words of the email body (unlike iOS).

I added my own shortcuts and deleted all the preset ones (Wikipedia, Twitter, Amazon etc). On deleting the last one of the default ones, the 'Add a shortcut' button has completely disappeared. Is there another way to create a shortcut?

I would like the address bar to show what it would show when you type a "?" just by clicking. It's a default feature in chrome, I know, mentioning a competitive browser as an example is kind of a no no, but it's the only example I can think of.

Blocking remote content by default is a very positive security feature. But needing to add each and every email address individually is NOT optimum and wastes a lot of time. We really need a method to globally allow remote content from specified domains. For instance, it would be handy to allow remote content from any/all email from IBM, but I certainly don't want this for gmail.com addresses. This seems like a very simple improvement to code.

How can I get Thunderbird to instantly download all new mails from the server - instead of waiting for the standard mechanism of Thunderbird to download new mails?

Hi folks, I am wondering if there is a possibility to add a strikethrough icon to the compose window. I use strikethrough quite often and it is very inconvenient to go to the menu each time. I can find only addons for earlier versions of TB. Thanks

Dear Sirs,

I have a common layout for folders. If I create a new folder, Thunderbird 115.10.1 (and previous versions) always uses a different layout. Sometimes I forget to change the layout and when opening the newly created folder I am confused. I find it also annoying to always apply my folder layout to the newly created folders.

Is there any method/setting to define/set the layout for new folders?

Kind regards,

Jens
