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.

upon opening firefox the following address appears in the search window:

https://eventseekspot.com/?path=firefox/newtab&u=864940da25d1ae22&subid=11119&channel=1

why? and how do i make it go away

Hyperlinks keep opening in new windows, not in the same/existing window where they were selected. Issue is not unique to Google Search results and occurring across multiple websites. At wits end trying to figure this one out. I have deselected the "Open links in tabs instead of new windows", turned off all extensions, and uninstalled & reinstalled Firefox. Issue is still occurring. Attached is image of my tab selections showing all turned off.

FireFox browser closed and when I opened it all my bookmarks are gone, all of my history is gone everything is gone as though I never ever used firefox in my life.

Since one of the latest updates, Firefox keeps randomly showing me a popup saying "pin this tab", pointing to a tab I just opened. I close it with its X button, but after a while it just pops up again. I don't want to pin a tab, ever - I have bookmarks for a reason and I don't see any point in this feature. How do I stop this incredibly annoying popup from bugging me constantly to do something I never want to do?

I have downloaded downloaded language packs English UK and French France, but when I spell check in Mozilla the only option in the open menu for language there is only English US to use even though the other two preferred languages have been downloaded. Am I missing a trick to activate the languages so that they show in my language menu when spell checking?

Very frustrating that I only have a default of US considering I am in France and use French and UK English.

I know you can block it and opt out of the AI options in Firefox, but just wanted to voice my opinion.

We did not ask for it, nor do we want or need it. The bubble's gonna pop soon and then we are stuck with these AI artifacts.

By default the AI options should be blocked/off/opt out. If we want to use it, we'll opt in ourselves.

There is an issue with MKV video playback with MP3 audio track in FireFox. The problem is that MKV video plays MP3 audio track without any sound. With AAC audio track the problem is that MKV video initially downloads whole video and only then plays it. In comparison with MP3 and AAC the benefit of MP3 is much better quality and it starts playing without downloading whole video like MP4.

It would be nice if you add support MKV video with MP3 audio playback.

Cannot connect to BBC Sounds web page (https://www.bbc.co.uk/sounds). Get the following error message: "The page isn’t redirecting properly Firefox has detected that the server is redirecting the request for this address in a way that will never complete. This problem can sometimes be caused by disabling or refusing to accept cookies."

Have tried with and without a VPN, have cleared the cache, and shutdown/restarted Firefox, but no luck.

Connects without issue when using alternative browsers.

I have a small usability suggestion regarding browser password managers.

When a website changes its domain (for example, from example-old.com to example-new.com), existing saved login entries keep the old domain. In many browsers, users cannot edit the domain field of the saved login.

As a result, users must delete the existing password and create a new one, which is inconvenient when managing many accounts.

A simple improvement would be to allow editing the domain/URL field of an existing saved login entry.

Example: example-old.com → example-new.com

Instead of deleting the login, users could just update the domain.

It’s a small feature, but it would significantly improve password management usability.

Thanks for your work on building great products.

I asked on 11 January 2026 Help for finding back my cookies. Got an answer by e-mail, but this disn't help to find my cookies and so I cannot manage these. Who can tell me please where I can find all my cookies? Thanks in advance. Regards Theo Koeppen

Using 148 on Debian trixie I do not see the option for "refresh browser"?

Does it still exist or is there an alternative ?

Browsing this website article I can see that there are embedded Youtube videos in the article but they are not loading, instead I only see blank spaces. I've turned off all extensions, turned off tracking protection, cleared cache and cookies for both the website and Youtube.com, and tried viewing the website in troubleshoot mode.

You might be wondering why we lumped fractions and greatest common fractions together.
The fraction

The first time the inline table creates a new line second time inserts in fraction where it is (which is how I want it) How do I prevent it from forcing a new line?

It used to be that when I clicked ctrl+tab in the browser it would move through my tabs. Now, instead of moving to the next tab, it pops up a thumbnail preview and scrolls through those, instead. This is not useful to me. Is there any way to either revert the behavior or is there a new keyboard shortcut to quickly move to the next tab?
