Ihave installed and configured Google-4-TBSync addon to synchronise contacts between Google and Thunderbird and all works fine.

Just got an email from Google entitled "[Action Required] Mark AI agent OAuth clients as agentic for Google Workspace MCP by Nov 11, 2026"

Does anyone know if that is sometyhing I need to do for the addon to carry on working?

Thanks

I see a long list of recommended Badges and/or Extensions. I tried clicking on one but nothing happened? When I find an extension that sounds good, what steps do I take to add that extension to Firefox?

Hi

We are managing Firefox settings using Intune and successfully imported the Mozilla/Firefox ADMX files. A few settings are working as expected on a test device, though we're encountering issues with the Extension Management policy.

We followed this documentation to set up the extension management json: https://firefox-admin-docs.mozilla.org/reference/policies/extensionsettings/. I can see the policy is loaded into Firefox, though I am unable to add uBlock Origin, which should be allowed. All extensions are blocked, and the custom error message does not appear either, but instead "Download failed. Please check your connection."

I've tried a few variations with mixed success, but I haven't been able to get "allowed" extensions to work. Force installed extensions seem to work just fine.

Here's a minimal policies.json that demonstrates the issue:

{

   "*": {
       "blocked_install_message": "Custom error message.",
       "installation_mode": "blocked"
   },
   "uBlock0@raymondhill.net": {
       "installation_mode": "allowed"
   }

}

Is there something I'm missing? The test device is running Firefox 156.0.1 64-bit, firefox.admx 8.3, mozilla.admx 4.8. Any help or suggestions would be greatly appreciated! Thanks.

I use Read Aloud in Firefox on my gmail. Sometimes it works and sometimes it gives this message:

"Missing host permission for the tab", It gave this message a couple of mornings ago and later in the day it could read the same gmail. Today it is back to not being able read multiple gmails. The extension is ver 1.71.1 and Firefox is 157.0.1 (64-bit). Windows 11 PRO 25H2.

Now it is working again on my gmails. Read Aloud is a critical tool for me. Last week it was working all the time. I complained to the text owner(The Bulwark for instance). in a couple of situation. Now I feel foolish because it probably isn't their fault.

I am having difficulty understand where to start downloading Bookmark Dupes. I am not sure if it is the answer to my problems. I want to reorganize folders mess with duplicates ,layout order deletes and duplicates while maintaining most content

Hello there, I'm trying to add the surfshark extension to Firefox but I keep getting a pop-up asking if I want to go ahead and add the extension to Chrome. When I click cancel it just closes the pop-up, clicking 'Install now' just brings it up again. I've just istalled Surshark.

Any ideas ?

I want to change the YouTube logo or theme using browser extensions, but I am not sure how to configure it correctly. Could you please tell me the steps to customize the YouTube appearance?
