Until recently, when I clicked on a link in Thunderbird, it was opened in Thunderbird. Now the link is opened on a wide-screen external monitor. I can't find the setting that was changed to make this difference.

Thunderbird links open in a new, clean Edge profile instead of my Default profile

I am experiencing an issue where clicking links inside Thunderbird emails forces Microsoft Edge to launch a completely brand new window with a blank profile (no extensions, default settings). It does not open as a new tab in my active window.

My environment details:

• OS: Windows 11 (Version 25H2) • Default Browser: Microsoft Edge (Only one profile exists under edge://settings/profiles, no Workspaces used). • Thunderbird version: Latest stable release.

When Thunderbird passes the HTTP/HTTPS link to Windows, Edge seems to ignore the standard "Default" user data directory profile and launches a temporary or guest-like profile container instead.

Is this a known bug in how Thunderbird handles external URI handlers, or is it an Edge registry/default app assignment issue? Any help or workaround config settings would be appreciated. Thank you!

I'm running Thunderbird Ver 152.0.1 with Windows 11. I have things set up so that I just need a single click to open a program, folder or file.

This also was the case until just recently with Thunderbird. I could open new messages with just a single click. For some reason this has changed to me needing to double click to open new messages.

I don't know why and cannot find any method of changing the software back to single click operation. It is only affecting Thunderbird all the Windows operations still operate with one click.

Can you advise me on how to reset the Thunderbird software to single click operation.

Many thanks. Alan Tierney

I have attached a screenshot of the retention settings for the Gmail All Mail folder. This folder contains emails that have a date nine years ago. Can you tell me if I did something wrong in the retention settings?

I thought earlier today it was using the retention settings but I just checked and it is not.
