Good Morning! I've just come back to FF after using another browser for quite a few years. Things have changed alot here, but I'm loving it all so far! With that being said, have been trying to get a few extensions set up. Main one being Open Link with New Tab. (WHY doesn't FF do that automatically? lol.) Anyway, obviously I'm doing something wrong because it just stays grayed out. I've uninstalled/reinstalled quite a few times. I know it's something so basically simple and I'm overlooking it. HELP! Thanks! Lynn

Description: I need help with the "Firefox Multi-Account Containers" extension.

The extension is installed and shows as "enabled" in my Add-ons Manager. However, the colorful container icon does NOT appear on my toolbar, so I cannot access or use the extension at all.

What I have already tried (none worked):

· Dragging the extension icon from the puzzle menu to the toolbar · Right-clicking on the extension icon (inside the puzzle menu) to see if there is a "Pin to Toolbar" option — but the option does NOT appear at all · Restarting Firefox multiple times · Restarting my computer · Creating a new profile in about:profiles and testing the extension there — still no icon · Disabling and re-enabling the extension

The extension is installed and enabled, but without the toolbar icon, I cannot create containers or separate my Gmail accounts. I really need this feature.

I have read that this might be a bug in recent Firefox versions. Is there a known fix? Do I need to completely uninstall Firefox and reinstall it? If so, could you please guide me on how to do a clean uninstall (removing all profile folders and registry entries) and then install the latest version?

My system is Windows (older version, if that matters).

Thank you very much for any help!

Every time I see a box to enter a username or on some websites, any box that needs information filled in, a pop-up box appears that says "unlock your password manager." I was finally able to get to a website at moz-extension://b5ea3638-1832-4174-a490-4c5e77c0dbc6/html/index.html. The page says "Welcome My Financial Expert Password Manager securely stores, organizes, and autofills your logins, passwords, and more. Sign in to get started." Is this a legitimate mozilla extension? Is this a scam? How do I get rid of it (it's REALLY annoying!)? Thank you for your help and any insight.

I use Dashlane as an extension in android Firefox on my Acer Swift GO 16 laptop. I use my fingerprint to log into the laptop but in the security settings in the Firefox Dashlane extension I see the message: "Your browser does not support biometrics. To use this feature, install the Dashlane extension using Google Chrome or Microsoft Edge." I prefer to use Firefox.

Why is the option to use Biometrics (fingerprint in this case) not available?

Until some days ago I could use the add on "Video Downloadhelper" without problems on my old Macbook Air (2017) with OS10.15.7 but suddenly the add on was not available anymore. I purchased a valid license for this add on. In the Firefox adjustments it was mentioned as deactivated. Could you please let me know, how I can activate the Video Downloadhelper again? Thanking you in advance for your kind support. Sincerely, Ulf Gaertner
