Firefox says versions earlier than 115.13 will be impacted by the certificate expiration. I've updated to 115.21 My add-ons are still disabled. https://support.mozilla.org/en-US/kb/root-certificate-expiration

It seems many don't know or haven't noticed but merely running an esr branch (rather than a developer edition) will also give you the option to enable add-ons with expired certifications via about:config.

Anyway, the "legit" way isn't working.

I have been setting up Passkeys to log in to the websites which allow them. But I have noticed on Paypal, they do not allow me to use passkey when using firefox, it only seems to allow chrome

Is there an issue with firefox which deems it not suitable for passkeys?

I noticed that sopmeone asked this question this time last year and it was advised that firefox is now able to create and store passkeys Paypal still dont seem to allow it?

Whay have extensions stopped workong with latest Firefox update. E.g. Last pass is listed as an installed extension but clicking in the installed list just gives a settings page, and there is no button to enable pinning to the top bar, so I can't access Lastpass at all in this way. Have updated Firefox to 134.0.2 and reinstalled the Last Pass extension but no change. Previously I have been able to pin Lastpass extension to the top bar next to the Download icon. Other icon that do work: Pocket, Download, Account, Noscript, Duckduckgo search, ABP and jigsaw piece. When will this get fixed pleased?

Hi, When I want to open and see most of sites, this extension show me the pop up and message:

Ads Blocker Detected!!!

We have detected that you are using extensions to block ads. Please support us by disabling these ads blocker. Help me please to remove this Ab Blocker. Thank You.

How can I stop advertisers from changing my 'Settings' fields 'Home page and new windows' to their URL which brings up their page before I can enter my password? I'm on Linux Desk Top.

I downloaded an extension and can't do anything with it. There is no way for me to open it, all I can do is open up my extensions to see it then change permissions or delete it. It won't appear on my toolbar with other extensions. I've seen others ask this question and the solutions dont apply to me. People are being told to either right click and click pin to toolbar or to click the gear icon next to the extension and then pin to toolbar as well. I have no gear icon next to extensions and right clicking an extension treats it like a link. There is a gear at the top that when I click it I can click "manage extension shortcuts" only for it to then pretend none of my extensions have shortcuts even though 2 of them are right there in my toolbar. The 3rd 1 mozilla seem to not want me to have on my toolbar.

I'm chasing a problem with 1Password not auto-filling fields. please can you tell me how to delete Firefox and extension then re-install both. Firefox 146.0.1 MacOS 15.7.3

Thanks and happy new year

Hello I have Firefox 144.0 (64-bit) installed. I added Video DownloadHelper to Firefox, but its icon doesn't appear in the Firefox toolbar. I've tried using Toolbar Customization, but the Video DownloadHelper icon doesn't appear there either, so I can't drag it to the toolbar. Can you help me put the Video DownloadHelper icon on the Firefox toolbar? Thank you

Every few days a popup appears that tells me "An extension, Panorama Tab Groups, is hiding some of your tabs. You can still access all of your tabs from <down arrow>." It has two buttons: Disable Extension and Keep Tabs Hidden.

There seems to be no way to turn this off. I *want* the tabs hidden; that's why I have the extension installed. And I really don't want to be pestered with this popup like this. How do I stop it?

Hi there,

I’m using the Firefox Multi-Account Containers extension and would like to remove a site that’s been set to "Always open in [X] container." However, I don’t see a “Manage Site List” option anywhere in the container settings as seen here: https://support.mozilla.org/en-US/kb/containers

Here’s what I’ve tried so far:

   I’ve clicked the Containers icon and selected the gear ⚙️ to edit a container.

   I enabled privacy.userContext.siteAssignments.enabled in about:config and set it to true.

   I restarted Firefox (with session restore on), but still no option appears to view or manage assigned sites.

I’m on Firefox Desktop (Mac), and I’ve confirmed that I’m using the official Multi-Account Containers extension.

Is this a bug, a UI change, or something I’m missing? I’d really prefer not to manually edit the containers.json file if there’s a built-in way to manage these assignments.

Thanks so much for any guidance!
