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.

Why has Video Download Helper v9 by Michel Guteriezze been replaced by Video Download Helper by vdh? The original versions were perfect. The VDH version 10 vdh is straight junk!

I can no longer pin extensions/add-ons to the toolbar. My interface does not look like the one in the help section. I don't see a gear, I see three dots. And when I click on the three dots I don't have the option to pin to toolbar.

I am using Firefox 147.0.4 on Mac OS 26.3 Tahoe.

Is there any addon or feature within addons management icon (from toolbar) to Disable Extensions and Apps in one-click like Chrome has via this addon?

hi I would like ask if is any way manually to update Root Certificate for my old firefox 88 .My extension ublock stop working today .I try to this but not works in my firefox .

about:config xpinstall.signatures.required to false extensions.langpacks.signatures.required to false

I do not want to update my firefox .There is any way to do somthing to works Add-Ons.

I have added the "Firefox Multi-Account Containers." I see the container icon, indicating it is "contained."

I have clicked manage containers and created separate containers like news for instance. I switch between personal, news, shopping and used each supposedly separate container.

But, I see the same history in each, which is not what I expected. Do I need a different Firefox account for each container?

When I put my PC to sleep, my add-ons disappear and stop showing up, and I get automatically logged out of sites I was logged into. After that, a message appeared saying that Tab Session Manager was corrupted. When I tried to repair it, all 200 or so tabs I had saved previously disappeared. How can I fix this? I’m really stuck.

I've been extensively relying on the `Ctrl+Alt+X` shortcut to spin up the selected chatbot in the sidebar, but ever since I reset my pc (complete reset, cloud download of windows, clear all apps and files) and re-installed firefox, the keyboard shortcut isn't working for me anymore.

I installed firefox with chocolatey, upon noticing that the shortcut had stopped working, I tried to downgrade to v145, which didn't help either. So an uninstall and re-install later (this time manually downloading the installer exe), `Ctrl+Alt+X` still doesn't work. Although hovering over the chatbot's icon in the sidebar shows the shortcut in the tooltip.

More info: `choco uninstall firefox` created a backup of "Old Firefox Data" or something similar, could that have somehow persisted the malfunction across installs?

Any help would be appreciated! System: Windows 10 Pro Firefox: 146

I am almost BLIND, "dark reader" extension that I paid for but cannot activate is BLOCKING important functions like the CAM I need to read with. I have contacted him many times, he just cruelly plays with me. he just keeps telling me over & over & over to do DO what is impossible to do because what I need is NOT THERE!. I am done with him. I will have to PAY A CAB to drive me & my crippled computer to a computer tec. in the hope they can clean up his mess.

I've been using MAC (multi-account containers) for a few months. Awesome feature, especially useful for logging into multiple email accounts in the same tenant (M365, GW, etc). In the recent past, if I had an issue with a particular login, I could go to the Firefox Multi-Account Containers extension button on the top bar, click on it...then Manage Containers, select the container to manage, there was a set of options, one of them being "Clear Cookies and Site Data" (or similarly worded). That would clear the data for that MAC which would resolve my issue. Now. that option is no longer shown when clicking the Manage Containers button. I've included a snapshot of what is shown now.

The ability to clear the data for that particular MAC is invaluable. How can I get that back?

MacOS (26.3.1 a). Firefox 150.0 (aarch64)

P.S. I just found the "Report" option on the extension itself in the Extension settings. I will post this message there as well.

I have a few extensions in Firefox but if I click on the extensions button in the toolbar it now takes me to a Personalize Firefox page where, if I click on Extensions, it only gives me the option of turning them off or on and not to activate or access them. For instance, one extension is Volume Booster which cannot be adjusted on this page. How can I get back to being able to actually using these add-ons?
