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.

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..

When I went to https://www.mozilla.org/en-US/products/vpn/ and decided to purchase a Mozilla VPN prepaid annual subscription part of the reason was this "feature"

"Easy Firefox integration with the Mozilla VPN extension (Windows only)"

There is nothing easy when clicking on the download for the Mozilla VPN extension yields a message that the add-on or extension has been blocked. The explanatory link provided is https://support.mozilla.org/en-US/kb/add-ons-cause-issues-are-on-blocklist. That lets you know that:

"When add-ons violate Mozilla’s policies, compromise user safety or privacy, or fail to meet user expectations, Mozilla takes action. This may include disabling add-ons in Firefox to maintain a secure and reliable user experience. "

So, when will Mozilla stop violating Mozilla's policies so that the Mozilla VPN add-on is fit for use on Firefox v 149.0 [without free VPN] running on WIN10 64?

Hi there, I'm trying to upload a new version of my browser extension (version 1.4.5), but the submission is being blocked due to a version number conflict. The issue is that I accidentally submitted a different extension under this listing with version 1.7.7. I reverted it immediately, but now I'm unable to upload the correct version (1.4.5) because it's considered a downgrade.

I really don't want to change my extension’s versioning just to get around this, since 1.4.5 is the actual next version in my release cycle. At the same time, I don’t want to stop updating the extension on the Mozilla Add-ons store. Is there a way to resolve this?

hi, I was on the page where Firefox in recommending addons. But I click on a tap and it takes me to another page where the addon has a lot of detail explainations on the addon, but there is no where on this page to download or install the addon. I am interested in several of the addons. Can you guide me where to go to install the addons. Sincerely Andrew

On Firefox version 140.8 using a MacBook Air, shortcuts for Extensions no longer appear as icons in the toolbar.

Online guidance to get Extension icons back in the Toolbar have failed. One suggested following the jigsaw icon in the toolbar to 'Extensions'. But none of the links under Extensions included the option to 'pin to the toolbar'. Another suggested using the 'Customizing the Toolbar' route. That too included no option to add Extensions.

Anyone know a better fix? Your suggestions are much appreciated!

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.

Hello. I was curious and allowed accuweather but now I regret that and want to get rid of it. But I cannot find it anywhere on my Firefox account, I have been loking everywhere but cannot find anyway to delete accuweather. It feels like a malware and I cannot get rid of it. Please help. Best regards from Claes in Sweden

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.

How can I block the google account sign in dialog box on weather.com. I can't close it or get rid of it. It permanently obscures part of the screen. I use Windows 11 and the most current version of Firefox. This problem began within the last few months.

currently using FF; I do NOT have any ad blocking software installed ( that I know of) I searched my computer for the word block, and it did not show it anywhere. I also have Mozilla Seamonkey installed, but not using it. Each time I visit a news website I get a popup that claims Im using an ad blocker. I have searched all those adbocker pgms on my computer and none exist. Why am I getting these pop ups. I think I also checked the AVG pgm, but didnt see an adblocker there. How do I fix this situation from continuing

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.
