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Why has Video Download Helper v9 by Michel Guteriezze been replaced by Video Download Helper by vdh?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!

The moment my version of Firefox auto-updated to 141.0.2 (64-bit), all of my extensions disabled. There is no option to re-enable them and no indicator of why they are disabled.

I found that switching to a new profile allows them to work, but of course that's not really an option; I have huge amounts of custom stuff in eg. Greasemonkey that I cannot afford to lose.

What can I do to preserve my extensions without losing things like Greasemonkey scripts? Again, deleting them and reinstalling them is not an option if it would lose their individual configurations.

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

So I am running 31 add-ons. 30 of them ARE ACTIVE. (I've ALREADY ACTIVATED THEM.) Only 8 are showing up on the tool bar. I would like to select ONE that is not showing up for use. I have double, triple and quadruple checked, it is active...but it does not show up on that toolbar. I WOULD say that it is because there is not enough room, but there IS enough room for at least 3 others to be showing up. I can remember a day when there was 12 of them showing, and I had an arrow to select to see the "hidden" add-ons. That is not present. I cannot find a way to "show all"... unless it is just going to the install center to see that they are BOTH installed AND active. (Well, one is not active, but that is for a reason, and it's not the one that I want to use at this time.) While typing this, I tried something, I right clicked on the toolbar and selected customize, and I SEE the old familiar >> but it is grayed out. Once I click on "done" it disappears again. It is that ">>" that is missing. Yes, it's called "The overflow menu"... THAT is what is missing! How do I get that back?

hi, I have a bit of an issue, which I'll try to explain my situation first. Thing is, I mainly use ethernet (because I need to), but a tiny piece of my laptop's casing fell off, so now the ethernet cable isn't fixed, and easily disconnects from small movements. It rarely happens, I mostly avoid it, but not always. I could be using wi-fi, but that has it's own random disconnect issues (which I'll probably try to fix in the future, but that's not what this question is about)

my question is, if the disconnection happens in the middle of extension updates (they have auto updates enabled), will that break the update/the extension itself? Do I need to worry about that? Or will it cancel and fully restart the update? Does it make sure that everything stays not broken, in situations like that?

it would be great to know this about browsers in general (since I occasionally use some others), but I understand this is a Firefox forum, so I don't demand answers for that.

Hello. I developed an addon to delete multiple reddit posts. It's built with the help of claude but regularly passes ReferenceError: browser is not defined

I'm adding the 3 files for the overview. Does firefox need some sort of API? https://storage.to/c/IXAJT4jqn

Hello, I have Facebook Container installed (Windows 11) on my desktop. However, if I click a link to a FB page, say in an email or on a webpage, Facebook opens onto the current tab and makes it a container tab. Since I can not go back once FB is opened in the container tab, I have to open a new tab and go back to the original (pre FB) webpage. This is the only time this happens.

What settings can I change so that the Facebook Container opens Facebook into a new tab, not on top of an existing open tab?

Many thanks for the millions of us that are computer challenged.

Dear Sir,

Firefox is not working with Rabby Wallet and Metamask extensions.

It does no pop-up the window to see the transaction and sign it. Firefox 134.0.1 (64-bit). Windows 10 Home.

On Metamask at least I can click on the pinned extension and see the window. However it´s not the expected behavior, because it should open the pop-up automatically. With Rabby wallet it is impossible to proceed, even clicking on the extension icon.

Please fix it asap.

I have McAfee+ Ultimate Family Security package and was attempting to set up its Password Manager. As it worked out their tech rep indicated that Firefox (which is my default by choice) does not support that particular extension for some reason. Is Firefox/McAfee collaborating to resolve this issue?

I have just re-installed MW due to probs using the original one, but now I cannot enter my registration code,(life time) there is no where to do so it seems,have looked everywhere?
