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.

In Firefox version 149, there is an issue with print preview behavior for HTML <select> elements. When opening print preview, all <option> items inside a dropdown are displayed and included in the print output.

This behavior differs from Firefox 148, where only the selected option is rendered correctly during print preview.

Steps to reproduce:

- Create an HTML page with a <select> dropdown containing multiple <option> elements. - Select one of the options. - Open print preview (Ctrl + P).

Expected result: Only the selected option should be visible and printed.

Actual result: All options inside the <select> element are displayed and printed.

Impact: This issue breaks the layout of printed documents and makes forms difficult to read, especially when dropdowns contain many options.

Default homepage is yahoo. Since the update to version 149, if I do a search from yahoo, the new tab that opens with the search result is blank most of the time. I have to click reload for the search results to show up.

Is anybody else having that problem? Seems to be yahoo search specific but not 100% sure.

After the latest auto update all of my history, tabs/windows, and bookmarks were deleted and I can't recover them. I have tried importing bookmarks and it does not allow me to upload an old data file and I can't restore my previous session. I tried checking both profiles but neither had my information saved and now when I open the about:profiles says "Another copy of Firefox has made changes to profiles. You must restart Firefox before making more changes."

I'm scared to try anything else because I don't want to mess anything up further but I really need my tabs and history back.

I restarted my computer and then reopened firefox and it had updated and I noticed my bookmarks were gone but my windows/tabs were open, so I tried to choose a file on the bookmark backup and nothing was happening so I restarted and after that all my history and tabs were gone and I couldn't restore them.

Is there a way to disable tab groups without going through about:config? Because I can't find it and there really should be...I have no idea how that feature works, I don't want it, but I keep ending up with groups unintentionally. I still don't know how I'm doing it. It's incredibly annoying and apparently incredibly easy to accidentally trigger and I'm sick of losing tab space to these random colored boxes for no apparent reason!

I'm not sure if it's Firefox's VPN or the most recent Windows ESU or a combination of the two, but really weird things are happening when I reboot my system and it tries to enter windows via my local account.

I checked AI and it said yes it is highly probable that the combination of Windows ESU and the newly added Firefox VPN is causing your system to act weird. Recent Windows updates have been known to cause conflicts with VPN software, leading to network issues and system stability. I've turned off the VPN in Firefox and the VPN setting in Windows VPN Advanced Options today. I did notice my system appears to struggle when it hits the McAfee program when trying to load the Windows Desktop Screen.

Hi,

I’ve recently noticed that after a Firefox update, the browser has become very slow and unresponsive whenever I open multiple tabs, around 5–10. Before this update, I could open many tabs without any noticeable lag.

Now, new tabs take a long time to load, scrolling within open tabs feels choppy, and sometimes Firefox freezes for a few seconds before responding again.

I’ve already tried restarting Firefox, disabling extensions one by one, and clearing the cache, but none of these steps have improved the performance. I’m using Windows 10 and the latest version of Firefox.

Could anyone suggest what settings or troubleshooting steps I can try to fix this slowdown?

Suddenly I cannot search from the search bar. It defaults to the address bar. why "fix" something that was not broken. Being forced to use the address bar is frustrating. If you go directly to the address bar, it tells you it cannot find that site.

Seriously Mozilla.

First with ramming AI everywhere in Firefox, now a browser VPN, why?

I do not want a VPN the web browser that I didn't ask for or other features you think people need without asking.

Corporate and business users would not have a bar of this either.

Enough!

Remove this from Firefox please in the next release.

In the meantime, tell users how to disable this VPN via the Settings and "about:config" so this never gets turned on.

I have years of bookmarks that have disappeared and my history is missing. Firefox opens with the tabs that were open when it shut down. I really want my bookmarks back.

I am trying to activate the new free VPN feature, however your steps are not matching what's on my screen.

The first step from your [Set up VPN] article says:

"Look for the VPN setup prompt in the top-right corner of your Firefox toolbar.

   Click Next to begin the setup process. "

Yet I am not receiving this prompt.

I have logged into my account, encountered issues with my authenticator app and back up keys not being saved, and so signed up with a new mozilla account using my secondary google email. (This account I am raising this ticket with now. My primary account/email is [edited email from public] @gmail.com).

Hoping you can clarify or give an easy route into activating this wonderful new service you've announced. Am I right in understanding that it is different (ie. built-in and free?) to your Paid Service ?

Can not use the modzilla VPN purchased for my 2017 Macbook Air. Operating system will not support it! Required credit card reversal for Mozilla receipt ZPQWEQ-0001 March 31/26.
