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 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.

How to delete the word finder toolbar at the bottom of the browser?

I tried to change the wallpaper but instead found different color settings for the browser. I selected one, but nothing changed, except now I have this word finder toolbar so anytime I type something it pops up and I have to reset focus every time from it back to my computer page. This basically makes my computer unusable.

Why are you trying to chase people away, after update i had to reinstall it cause nothing functioned right, now I have to jump through hoops just to install ad Guard. It should not be this difficult to use a website. I think I will move over to chrome where they actually try to make life easier and not more difficult

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

Can I change the directory where Firefox stores the add-on xpi files? Our company's IT dept is constantly deleting or corrupting them. Right now it's: C:\Users\User\AppData\Roaming\Mozilla\Firefox\Profiles\riqfpq8g.default-release\extensions If I could just add a folder and tell firefox where the files are, this might solve that problem. Any ideas?

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.

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?

I have two accounts n Youtube and the same video downloader app installed. in the first account I cannot download any video and i get the message "no links ere found". if I switch to the second account in the same video, I have no problem and I do download the video. what can be the solution to the problem?

I installed the extension with the first account which I use as the primary one. at the beginning and for a few months it worked fine and suddenly it stopped working. I didn't do anything. I changed to the second account for other reasons, and I noticed that the downloader works without any problem.

I'm using Firefox v126. I'm searching through the add-ons trying to find a few that I like and most don't work with my older version of Firefox. So I click into the version history of the add-on and find an older version of the add-on that will work with the version of Firefox I am running. Except... I click it and I get:

"The add-on downloaded from this site could not be installed because it appears to be corrupt."

say what? ok maybe a fluke, so I click on through, older version, older version, still old version. All give me the same error. Okay, maybe its just the add-on, no, its literally any older version of any add-on.

No way all those versions of add-ons are "corrupt." I can download the .xpi, rename to .zip and view the contents. Anyone run into this particular problem before and if so, how did you fix it? I'm keen to keep v126 of Firefox and would like to use the add-ons that I like to work with it.

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.

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?
