When the "Delete browsing data on exit" feature is enabled in Firefox for Android, the app correctly clears selected data types (e.g., Browsing history, Cookies, Cache) upon exit. However, the "Recently closed tabs"list is completely unaffected and remains intact after restarting the app.

Download Issues My downloads have stopped displaying. Each page of a download is now just a black screen. Any advice as to how I can restore them?

Hello!

I have installed Thunderbird 150.0 on an Ubuntu 24.04 desktop using a downloaded TAR installation method. I have done this, as I use OWL for Microsoft Exchange accounts. OWL works better with the current version of Thunderbird.

I have created a desktop launcher (thunderbird-150.desktop), which works fine, except that the software icon is the generic Gnome gear. I have read that specifying the WMClass correctly in the launcher file (in /usr/share/applications) is the solution, but this does not seem to work. It is current set as WMClass=thunderbird. I have also noticed that the /opt/thunderbird/icons folder does not contain the Thunderbird icon.

Can anyone help me to fix this annoying issue?

Many thanks!

i am experiencing an issue with firefox where backup (Firefox Backup) is not working since version 148.0

problem: - when I try to create a backup, i get the error: “Hmm, there was a problem with the backup. Please try again in a few minutes.”

what I have already tried: - enabled and disabled backup password - changed the backup folder/location - cleared browser cache - tested across multiple updates (issue persists)

- backup is enabled, but I cannot create one - the error occurs every time - restarting the browser and system did not help

Hello!

I am using Thunderbird 140.9.1esr (64-bit) on a Ubuntu 24.04 system. Every time I restart Thunderbird, it reverts to a little used Gmail account as the default account. I have several accounts, but my main email account is a MS365 account. I reset the setting, but every time it is restarted, the default goes back to Gmail. I have tried everything that I've found online, but cannot correct this behaviour.

Do you have any suggestions or assistance?

Many thanks!

I once signed up for a stock service, which included a daily popup. When I found I did not need/want it, I discontinued the service and deleted all of the related files. But the daily popup still remains and occurs. When I contacted the service they said it was something still attached to the browser but could not tell me how to find it or remove it. I have looked at everything I could think of but cannot find any reference to 'Weiss' (service name) or any name anywhere within Firefox. What am I missing? Many thanks Jim Bigger

I am attempting to install/activate the built-in VPN feature in Firefox v150 on my Mac OS Tahoe 26.4.1 I have checked the various FAQs and followed the instructions but nothing seems to identify a built-in VPN. I have logged into my account per instructions and I do not find any icons on my toolbar to indicate setting up the built-in VPN. If I did dismiss this at some point, I am not able to recover the icon/application and continue my setup.

Any assistance would be greatly appreciated. Thank you.

To open Thunderbird I must enter a primary password. This is driving me NUTS. When I open the program, I want it to start without having to remember a password. Also, if something happened to me, nobody else in my family could open the program without knowing the password and how to find it if needed. After many decades of using this program for email, this primary password nonsense has become a great annoyance. FIX THIS STUPID PASSWORD PROBLEM. Please.

Due to muscle menu or not needing to think about it. Split should either be near the bottom of the context menu or you should be able to toggle it in settings. The amount of times I have gone to click a link to open in a new window only to split the view is driving me crazy.
