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.

I did reach out to GitHub. They referred me to contact the Video downloader support team, which is not part of their development.

Your response Number 2 If you are referring to this Extension https://addons.mozilla.org/firefox/addon/video-downloadhelper/ Look on the left side for the Support site link in the more information panel. It leads to https://github.com/aclap-dev/video-downloadhelper/discussions

My question is addressed once again, "Third attempt?" Please give a direct reply. Firefox should have the contact information since you permitted it to be part of your browser extension.

Back to my original question posted here once again Recently, the video downloader helper stopped working with videos of YouTube links. The video downloader helper on the Firefox window is grey, meaning inactive. I tried using a video from a LinkedIn web page and was able to download it. Any suggestion? I recently purchased the license for a video downloader helper. Thanks Arvind [edited email from community support forum]

When I open Amazon's page a splash screen appears that takes up a third of the screen. This splash screen provides keystroke shortcuts. Are you responsible. If HOW MAY I PERMANENTLY ELIMINATE THIS ANNOYANCE?

How to edit shortcut keys for the extension- Read Aloud: A Text to Speech Voice Reader ?

When trying to assign a new shortcut of my choice, it gets deleted automatically.

I was able to do so in Chrome and Edge browsers.

Please help me to assign the same shortcut keys in Firefox also..

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.

My question is above!

I had a free chatGPT on firefox sidebar. you changed it to Anthropic Claude without my permission. Now I have to pay for something I was getting free as a student of a university.

How can I restore the FREE ITEM AND GET RID OF SOMETHING I WILL HAVE TO PAY FOR...AND STILL USE ai?

I am 82 years of age and did not grow up with the Internet. I have a total of only 8 hours of training on a PC. I have no idea how my PC got into 'safe mode' and now all of my extensions are disabled. I do not know how to exit 'safe mode' to allow the extensions to be enabled again. I tried following the instructions as provided, but to no avail.

Hello, Mozilla. I really appreciate the way you think about internet access. What you stated about the app is truly reflected within it: fast connections, accurate results, and most importantly, the security. However, when it comes to advertisements, I was really expecting that whenever I watch YouTube contents, there will be no ads shown. To my surprise, ads are still there. I provided a snapshot of my desktop to give a proof about this. Is there somehow a way to get rid of them, like perhaps an extension to block ads? If there's none, that's fine as well. Thank you and high praise to the developers of this browser.

I am running Firefox 148.0 and Thunderbird 148.0. I am in the process of moving everything to a new (to me) computer that will run Windows 11. When I start Firefox from the start menu or the taskbar everything runs as expected. I have the Adblock Plus extension plus several others running. If I click on a Hyperlink in a email in Thunderbird instead of opening in a new tab into the currently open copy of Firefox as it did on my old computer running Windows 10 it opens in a new window with no extensions. I am assuming that I have something set incorrectly. Any help as to where I should look to fix this issue would be greatly appreciated.

I'm on WinXP and Win7; FF is there respectively on ESR 52.6.0, and 56.0.2.

• • Pls refrain from lecturing me on updating etc. I need it to be this way for umpteen reasons. Thanks for understanding.**

First, all of a sudden all my legacy add-ons were disabled. Most of them ensure FF looks like it did ages ago, which is what I'm used to, and need, to function properly myself. They overall are no longer maintained or downloadable, hence the need to stay on lower browser versions as well.

Managed to fix that.

Then, last Fri, my webmail provider missed updating their security certificate. They seemingly later do, but I am left unable to access their website from FF on both machines, and Chrome on the XP. Disaster.

The error messages I get are, in FF:

[www.netaddress.com] uses an invalid security certificate.

The certificate is not trusted because the issuer certificate is unknown. The server might not be sending the appropriate intermediate certificates. An additional root certificate may need to be imported.

Error code: <a id="errorCode" title="SEC\\\\\\\\\\\\\\\_ERROR\\\\\\\\\\\\\\\_UNKNOWN\\\\\\\\\\\\\\\_ISSUER">SEC\_ERROR\_UNKNOWN\_ISSUER</a>

and in Chrome:

classic.netaddress.com normally uses encryption to protect your information. When Google Chrome tried to connect to classic.netaddress.com this time, the website sent back unusual and incorrect credentials. This may happen when an attacker is trying to pretend to be classic.netaddress.com, or a Wi-Fi sign-in screen has interrupted the connection. Your information is still secure because Google Chrome stopped the connection before any data was exchanged.

You cannot visit [classic.netaddress.com] right now because the website uses HSTS. Network errors and attacks are usually temporary, so this page will probably work later.

When running a SSL server test on their certificate it turned back: Chain issues Incorrect order, Contains anchor

No idea if that's relevant.

I tried just abt everything I was handed, could think of, or googled. Adding an exception included. Nothing works. Logically, the error should be on their end (w/ their old certificate, it all worked fine, now it doesn't), but somehow I keep being directed to that your root certificate having expired is the culprit.

Earlier today, I took the plunge and updated FF to 72.0.2 on the Win7 machine. (My webmail doesn't have full functionality on Chrome, so I was still very hampered in that regard there.) Now I can access the webmail -- but all my add-ons AGAIN are disabled. And what I did before to make the work does now NOT work anymore.

Can someone pls take me out of my misery? My whole existence is falling apart. I am already on 75 % (invisible) disability. Nothing works, least of all I. I am days behind on an already massively overburdened schedule. Not everyone can handle constant updates and their user interface being changed all the time. Some ppl are dependent on things looking and acting the exact same.

I'd like my add-ons back functional on the Win7 machine, and my webmail back -- INCLUDING the add-ons remaining functional, on the WinXP. Thank you.
