The File (saving to a folder) Recent function used to have the folders alphabetically. Some genius thought to reorganize the Recent folders to be in chronological order. Is there a setting to have the Recent folders be in alphabetical order again? I could not find anything. Thanks in advance.

Over the past few updates, I’ve noticed an issue with Firefox where it no longer restores my previous session when reopening the browser.

I normally keep four tabs pinned and about five additional tabs open for browsing and work. In the past, I could simply click the X to close Firefox, and when I reopened it, all my tabs that are pinned and unpinned would automatically come back. Recently, this stopped happening. Now, if I close Firefox, it opens with a fresh window instead of restoring my previous tabs.

I’ve already checked the setting under General/Startup, and Open previous windows and tabs is enabled. Because of this issue, I avoid closing Firefox entirely, since rebuilding all my tabs each time has become a hassle.

Is there a way to fix this? Any suggestions would be appreciated.

Thanks :)

I copy/paste emails a lot for my job, which needs to include from, sent, to, cc, bcc, and subject:

From: Sender <sender@email.com>; Sent: Wednesday, January 21, 2026 at 11:27 AM EST To: John Doe <johndoe@email.com>; Cc: Jane Doe <janedoe@email.com>; Bcc: Subject: Email Subject

Currently, I am using the plugin ReplyWithHeader, which will produce this style of header on reply/forward, but is there a way to display this in the email body on view, without me having to reply/forward to produce the headers in the email body?

When I am typing an email in Thunderbird, regardless if I have my font size preset to Extra Large, Large, or Medium, the font that appears in the email while I am typing the email, is very tiny, so tiny it is hard for me to read it. Yet when the email is received by the recipient, the font appears the correct size as selected in composition settings. How do I fix this?

Hi,

I’m experiencing an issue while trying to print emails to PDF in Thunderbird. Instead of opening the print preview or print dialog, Thunderbird sends the email straight to the default printer. Because of this, I don’t get the option to choose my PDF printer or adjust print settings.

This started after updating to a newer Thunderbird version, and earlier versions did not behave this way. The menu still shows Print…, which normally indicates a preview or settings window, so this feels like unexpected behavior.

Has anyone else faced this issue, or is there a setting or workaround to restore the print preview before printing? Any help would be appreciated.

Thanks!

How do I remove the pop up blocker on Firefox for certain websites? I am doing an online course and each introduction for each chapter has a short video that pops up but as soon as that happens Firefox sends a "Critical error" message then the video stops so I thinks that's happening because pop up blocker is turned on and I just dont know how to turn pop up blocker off for specific websites only like this one I am using for my study course. How can I turn the pop up blocker just for this one website so that this doesn't keep happening?

Hello, I just installed a clean version of Thunderbird (version 146.0.1) and set up my email accounts and CardDAV address books.

I do have multiple address books and I tried to find a setting to show the name of the address book for each contact shown in the suggestion list for recipients when composing a new email. However, I could only find a general setting to get suggestions for recipients from local address books, nothing more specific.

On a different device I still have Thunderbird 140.6.0esr installed. There, the suggestion list does indeed show the name of the address book next to the suggested contact: "name of contact <email@address> - name of addressbook"

I tried to find a corresponding setting for this in version 140.6.0esr, but without success.

So I'm wondering:

1. Did the style/layout of the suggestion list change in recent versions?
2. Does a setting exist to show the name of the address book in the suggestion list?

Additional info: The only extension that is installed and enabled on both devices is ImportExportTools NG.

the only reason ive been using firefox is because its one of the few browsers that doesnt use AI. now this? anthony enzor-demeo what in the hell is wrong with you? no one wants this, stop pushing AI in a browser we all use SPECIFICALLY to avoid other browsers' (like chrome) sell out. i dont care if there's opt out I don't want this to be an option in the first place, and I know a lot of others feel the same.

i am not the kind of person who has brand loyalty, and if you continue with this I'll find something else to use.

The folders in my "LOCAL FOLDER" file usually have been in alphabetical order. As I have added new folders to store emails, the new folders have not been put in alphabetical order in the "LOCAL FOLDER" folder. They have been added to the end of the original list after the "Z" items. How do I re-alphabetize the whole "LOCAL FOLDER?"

Is there a way to turn off the “shake for AI summary” function on IOS? It doesn’t add anything to my experience, and more often than not, I end up accidentally shaking my phone and getting a summary I didn’t ask for.

If there’s a way to completely turn off the AI features, i’d like that too I’d prefer if my browser didn’t summarize the websites I visit in a way that can be inaccurate or lie to me.

Mozilla, please just remove these features entirely. If we want AI, we can go to ChatGPT or another website, I just don’t want it added into everything I use all of a sudden.

Thanks in advance for any help. :)

Have: When quoting, "start my reply above quote" and place my signature "below my reply (above the quote)" but signature continues to show below the quote.

What have I missed in this setup?

Is there any way to disable the ai summary feature on the mobile version of Firefox? I despise it , and if Firefox continues adding ai features, I’ll just uninstall

I have version 146 of Thunderbird. My OS is Windows 11. The Local Folders in Thunderbird are out of alphabetical order.

I have list of 130 local folders that are in the correct alphabetical order. Under that list, I have another list of 25 folders, starting with the letters L - U, that are in order alphabetically. I have tried to move several of them back up into their correct place in the list of 130 folders that are above them. This worked well for about 10 folders. Now, when I try to move a folder from the second set to its correct place in the group of 130 folders above them, they all end up in the same spot, between folders starting with De and Dra. When I try to move them away for this location, into their correct alphabetical slot, they will not move.

Also, when I try to create a New Subfolder under Local Folders, it is not created in the correct alphabetical location.

Does anyone know of an easy to correct these errors? I need to get my local folders in the correct order alphabetically again. Thank you.

Just installed Thunderbird on a new laptop running Windows 11. Accounts are set up and I can see all the emails in my inbox. They are in the Table View. My problem is that I can not view the contents of the email. I used to be able to click/highlight a message and its contents would be displayed below the list of emails. I am unable get this view. Can you please help. Thank you, Jim

I often use the key combination Ctrl+Alt+X in Google Docs when on different devices but it doesn't function properly when instead it brings up the AI sidebar gadget. Removing the sidebar button doesn't really help and it's annoying. So how exactly do I turn off the key combination for the sidebar?
