Why has Video Download Helper v9 by Michel Guteriezze been replaced by Video Download Helper by vdh?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 don't plan to use any provided AI chatbot. I want to use models that I have downloaded and tested myself and which run on my PC. So please add the possibility to connect through major LLM APIs, the same way other tools way simpler than Firefox already allow to do.

I PAID for "dark reader" I got the activation key but I cannot activate it because the instructions says go to "MORE" and there is NO "MORE"! I hunted all over the settings & extension & themes, but I cannot find anyplace to activate this extension. Did I just waste my money? I have poor vision, I NEED a dark page with white letters. Thanks to being a touch typist, I don't need to see the keybord or page to type but i can't see what I am typing on a dam w hite page! I now cannot click on "Email me when someone answers the threadil"

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 have just had to replace my PC following a bit of a disaster with my old one. The new PC has Windows 11. As usual I downloaded Firefox as I always use this. Somewhere in the installation of Firefox I must have been asked about blocking ads, but I don't remember. Now all ads are blocked, which I don't mind, but some sites are asking me to disable my ad-blocker if I want to use their site. Mostly I don't but there is one I need to use, so I would like to add that site as an exception, but I cannot find any mention of any ad-blocker in settings. Where do I find this? and how do I add exceptions?

The only add-on that I have in Firefox is the 'Privacy Badger' which could be the problem I suppose, but I can't see the website listed in the ones Privacy Badger is blocking.

Any help would be appreciated

bold text simple question - i want to add Grok to the AI sidebar options... why doesnt the Grok addon work any longer Im using the latest firefox as my default 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.

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..

If I use extension 'Block Site' (shows up as a stop-sign shaped icon with a 'W' on it) to block a site, when I try to unblock it, it fails, with the below message:

"This operation cannot be performed in incognito mode. Please open the page in a regular browsing window and try again."

I am just clicking on the (whichever) site, from a search - not opening a private window... This extension used to work fine.

I did install DuckDuckGo browser, but removed it, as it was more trouble than it was worth. I would have to reboot my PC after each use before FireFox would connect.

I have been using Easy Screenshot for years. Today I tried taking a screenshot and it opened a huge copy of the rectangular image I wanted to save in a new tab. Then there was no visible way to save the image. I used to get the option to save the image file in the same tab as the image I wanted to save. Took a screenshot and saved in Paint to show the contents of the Firefox window that image is huge and should have been 4 inches wide at most. Also the lack of how to save the image.

I'm wondering if this a because of the latest update. Firefox 147.0.1 X64 desktop WIN10 22h2 with ESU

When I tried reporting the problem on the add-on page the website it tried to connect to was not working so asking here for help.

As usual on forums, none of the subject choices exactly fit my situation/problem, so I apologize for any unintended misdirection.

How do I uninstall Privacy Badger. It's been disabled, but not uninstalled. Please be specific as to keystrokes, screens, boxes, location of item. Many instructions tend to overuse computer jargon or common industry synonyms used daily within their sphere, which a laymen cannot easily translate, and often raise more questions than they answer. Installed on my Firefox browser. Thank you in advance.
