Hi. Now that the 'Open Link in Split View' has annoyingly replaced the spot previously held by 'Open Link in New Window' i keep clicking on it accidentally (muscle memory).

I don't want to have to retrain my muscle memory, but despite creating css file generated by Claude that should in theory remove the option, and putting it the Profile Folder, it will not go away.

How do i remove it?

New to Thunderbird.

I have added a Gmail account to Thunderbird. I select a message in Inbox, right click > Move To > Local Folder

It seems to work. It creates a copy in Local Folder.

However, a few seconds later, the message reappears in the Inbox. The message in Local Folder is still there, confirming that copy is made successfully.

Also, the message is still in Gmail account when viewed from Google's Gmail. It's clearly working like Copy rather than Move.

This is frustrating. Is it a bug?

When opening the firefox nightly password manager and selecting a password, you have the possibility to edit your saved password by clicking the edit button. After clicking it, you are able to modify the username and the password itself. However, you cannot modify the url/website this password was saved from. For example, I manually entered the login and password for, let's say, my reddit account. However, I misspelled the website and typed in reddot.com. Now, I cannot modify this passwords corresponding website and have to delete it, and make another one where I don't misspell the url. If this is the case for technical reasons/limitations, then I totally understand. However, if this is the case because it was overlooked, then I'd be looking forward to seeing it in future updates.

I apologize for the mess I made entering duplicate requests. The is the latest UPDATED request on 6/24/2026 at 3:30 PM EDT

I'm using Firefox for Android version 152.0.1 (Build #2016167575) on a Galaxy S24 Plus phone running Android 16.

Firefox is set as the default browser. It always opens whenever a task requires a browser. But when I try to open an HTML file by tapping or long pressing it, the dialog window that opens doesn't show Firefox as an option. Screenshot_#1_20260624.jpg

I have checked the settings in "Apps that can open links", all apps there show "In other app" In "Default apps", Firefox is under "Browser app". Screenshot_#2_20260624.jpg

What do I need to do so Firefox is either the default app for HTML files or at least shows up in the "Dialog window"? Screenshot_#1_20260624.jpg

Thank you!

I just can't get Thunderbird to work. Will not send or receive emails. I had chat gpt help, still nothing. I tried last year when I had windows 10, still didn't work.

bold texti have a thunderbird profile on exterior drive I have installed linux mint on my PC but cannot locate the profile to use my old TB profile -either by replacing it or renaming the old profile for the linux one

i already tried to delete the cookies and cache, but 1 user is still muted for no reason and everyone/everything else works fine, so is there something wrong with the browser ?

i basically got like 2-3 completely different users muted for no reason, but at the moment i can only remember 1 of them and noone else has been added to the bug list ever since... and it basically happened when the Firefox itself got really low on memory again and started to display that red crash button. and even then, many different users crashed, but some did not even get the sound back anymore, while others did with no issue....

ps. i also found the other streamer now and both of them i was following, so that is also really weird, plus i havent noticed anyone else getting muted again, so maybe its just the ones that i followed ??? (and during the red crash button then)

(specs are probably in the other "Firefox memory fail" thread)

Hello,

I am experiencing a severe issue with the macOS system print dialog handling in Thunderbird, which started immediately after updating to version 152.

Environment

   * OS: macOS Tahoe 15.5.1 (26.5.1)
   * Hardware: Apple M4 (Silicon)
   * Thunderbird Version: 152 (Issue present) / 151 (Works perfectly)

Description of the problem: When I use the native macOS system print dialog within Thunderbird and select either "Open in Preview", Instead of opening the Preview app Thunderbird bypasses the command and immediately sends the document directly to the default physical printer. The same happens with "Save as PDF", the file-saving dialog is first presented, but after entering the filename the document is also sends to the default physical printer rather than being saved.

Steps to reproduce:

  * Open an email in Thunderbird v152.
  * Select Print...
  * in the Print Dialog window, select "Print using the system dialog" 
  * The system print dialog is opened
  * Click the PDF dropdown and select "Open in Preview" or "Save as PDF".

  Result: The document is instantly printed on the physical printer instead of performing the macOS system action.

Steps taken:

  * Tested with Thunderbird v151: The macOS system print dialog works perfectly as intended.
  * Upgraded to v152: The issue appears immediately and consistently.
  * All other applications (Safari, Chrome, Microsoft products, Apple Mail) work correctly 

This seems to be a serious regression in how Thunderbird v152 handles native macOS print system events and dialog actions on Apple Silicon / macOS Tahoe.

Any help or a fix for this would be greatly appreciated.

Best regards, Michel

I have a problem loading the page "claude.ai". yesterday it was working perfectly but today Firefox shows me a blank page. I really don't know what to do. I tried to clear the cache, going in private mode, forcing a reset, closing and reopening. What's the problem? Thanks

I've switched from K-9 to Thunderbird for Android.

One difference I've noticed is that the message notifications remain in the launcher even after I've deleted those messages in Thunderbird. Thus, I have to handle messages twice.

Is there a setting to make notifications go away when the underlying messages have been deleted?

Thanks

Hi Team,

Greetings!

I need your assistance regarding password protection for the Thunderbird email client.

I have configured an IMAP account in Thunderbird and enabled the **Primary Password** feature. However, if I cancel or skip the password prompt during startup, Thunderbird still opens successfully, and all previously synchronized email messages in the Inbox remain accessible. The user is also able to view the mailbox and access email content.

My requirement is that "Thunderbird should not open, display any email messages or allow Send/Receive operations unless the correct password is entered".

Could you please advise if this functionality is supported natively or suggest the recommended approach to achieve this?

Looking forward to your guidance.

Regards, Ps Cheema

As per the title. I have allowed external content for one message (it is disabled by default). Finding the option to do that was easy, because there is a specific message with a drop-down menu to configure access to external content for that particular message.

However, now that I have allowed external content, I do not wish to keep it allowed (no need for external parties to know when and where I open and re-open and re-re-open this e-mail). The drop-down menu to manage the privacy options for this particular message has disappeared. That is inconvenient, to say the least, because I can't see any other way to get to those options. What am I missing?

Well it never opens when I write ww. Wattpad. Com it's loads then says err timed out iver asked chatgpt and it suggested ask firefox so here I am do you think wattpad will work on Firefox cause it isn't working on Chrome Also I want to read the accardi obessions series

I have several MBOX files with me and I want to import MBOX files into the Thunderbird email client. I've come across different methods, including manual techniques and third-party tools, but I'm unsure which approach is the most efficient, especially when dealing with multiple or large-sized MBOX files. Some methods also seem complicated for users who are not very technical.

Suggest me any reliable tool for this!

Morning.....I subscribe to PennLive.com (part of the Patriot News group in PA) and have a paid subscription. For several years, there were no ads with a paid subscription. I also have set up on Firefox a custom anti-tracker which blocks cookies, ads and the like. it works on most sites. However, on Penn Live I am getting all sorts of ads jumping around many of which are just plain gross. Ads for belly and arm fat (with pictures), drinks for brain health etc. How do I fix this? What other protections do I need to add on Firefox? This needs to stop and contacting Penn Live has not made a difference. Thanks.
