Upon opening Thunderbird on a Mac (OS 26.5) the program posted a window requesting a password in order to add a new tool to the application. Unfortunately we have lost the password and the program insists it needs the password to continue. An option is offered to 'Ignore', but pressing this button does not launch Thunderbird, rather it sets up some Mozilla 'thingy' operating in the background (the Thunderbird icon in the dock is active) which can be terminated by Force Quitting the process. The thing is, Thunderbird is now unavailable at this point due to the new tool that could not be added to the application.

Some quite strange questions, which I'm not sure to which category it belongs to, While I use last FF on my main machine, I have another machine that still use firefox 56.0.2 since I like some of the addons there that never been remade/updated to newer FF versions,

It worked fine for years but suddenly all of the addons are disabled no matter what I've tried to do, Using backup, reinstall, about:config and setting xpinstall.signatures.required to false, you name it,

I was wondering if Mozilla pulled the plug on something or if some fixed date for things to expired has arrvied, As well as if there's a way to fix it in the settings/other means?

Some people said that Dev or Nighty edition can actually turn the xpinstall signatures to false while normal FF might have the option but won't actually do it, The problem is that I have no cluse which of their versions is equal to good old 56.0.2, Can anyone tell me?

Thx

Hello!

I first installed Video Download Helper several weeks ago and it worked fine. However, since the update of 04 March, 2026, it no longer works with YouTube. (It does, however, still work with Instagram.) Having checked all of the settings (which I had/have not changed), I uninstalled it today and then re-installed it. This hasn't helped. With YouTube, the Downloader icon (pinned to toolbar) simply remains grey and does not show any videos when opened. I am using the latest, fully updated version of Firefox with Windows 10.

Can anyone help, please?

Many thanks,

Stuart.

Upon starting Thunderbird today, it appears the connection to my two Outlook exchange accounts (through an Owl extension) are no longer functional. I can receive messages but I cannot send them. I have attached images of the error it returns first (Error1) and then the screen that results upon refresh (Error2). I can reach and send mail from my accounts using Outlook365 web access, so it must be a Thunderbird configuration problem. Please help!

I am having the same issue as this other user here: https://www.reddit.com/r/sysadmin/comments/17wvuwh/help_pinning_extension_in_firefox_with_gpo/

Preliminaries -- Initially (before trying to force-pin), I had these GPOs enabled:

Extensions to Install -> https://addons.mozilla.org/firefox/downloads/file/4410896/bitwarden_password_manager-2024.12.4.xpi

Prevent extensions from being disabled or removed ->

(Those GPOs above all work.)

What I'm trying to do: Force-pin Bitwarden.

I believe I've followed the documentation correctly (except for not including a "*" case): https://mozilla.github.io/policy-templates/#extensionsettings

I've enabled this GPO with this value:

Extension Management ->

{

 "{446900e4-71c2-419f-a6a7-df9c091e268b}": {
   "default_area": "navbar"
 }

}

After running various "GPUpdate"s and whatnot, the option to uncheck "Pin to toolbar" is still available to click.

I've verified in "about:policies#active" that the JSON item appears next to "ExtensionSettings" and that there are no errors listed in the "Errors" tab.

I've also verified that it appears in the correct location in the Registry.

Since another user had the same issue (Reddit link above), I figured it'd be a good idea to check in with y'all to see if we are missing something.

Thanks for your help!
