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.

Firefox just updated a few days ago to version 149.0. Prior to, no issues. Now every time I enter a search term and hit enter. A new tab opens and the page is blank. It only happened after the update. Closing the tab and doing the same thing again opens a new page correctly.

Using Firefox 145.0 (64-bit), "Firefox is up to date" on PC with Windows 11 Pro.

I was so pleased when Firefox's Group Tabs arrived. I often have about 12 tabs open to do Railway research. So I thought, Group Tab, great idea. Save a group of tabs as one tab. Instead of creating a Bookmark Folder and each time opening all bookmarks from said folder, what better way to do than opening one tab. Or so I thought. I also created a "SHIP" tab for my hobby in the shipping industry, so I could have two group tabs that could be collapsed making the tab bar tidier. I saved an closed each group tab then closed down my PC. Next on restarting, Firefox starts up automatically as chosen by me. Both RAIL & SHIP tabs reappeared without me doing anything. Great! However yesterday, I inadvertently opened another Firefox window, forgot it was opened. So when I shut down my PC, I closed the Firefox browser and then discovered the over Firefox window I had opened. Closed it shut down my computer. Of course when I opened my PC today, Firefox started automatically, but with the tab that I had open in the last Firefox window. No problem I thought, I will just open the saved Group Tabs. It was a problem, where are the Group Tabs saved? Could I find the location? NO! I looked in Bookmarks, all the various History lists, even the down arrow to list all tabs. Nothing, the Group Tabs are none existent. I have checked on the "about:config" section for Group Tabs and everything is enabled "true". So where are the Group Tabs saved? I have been with Firefox for around 14 years, often citing it as the best browser. But over the last five years I find myself using Chrome more and more. Chrome has Group Tabs which do not not need the users to save them, they are saved automatically, and are easily found on opening the Chrome browser. Why doesn't Firefox have this?

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.

Hello,all, The built-in translation button in Firefox disappeared on the Reddit website.

Please add a fixed access key for the 'Translate button'. I also recommend introducing an automatic website translation function. Thank!

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.

When trying to log into my work Microsoft Office 365 account on Firefox, a QR Code is supposed to appear, which I scan with my phone and the MSFT Authenticator app logs me in. This doesn't happen in Firefox but instead says, "Touch your security key to continue with login.microsoft.com. I am not using a security key and they are not allowed by my work. This works fine on Chrome based browsers.

Is there some setting that will fix this or is this a bug with Firefox?

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!

The picture-in-picture setting use to keep the detached video visible if I scrolled the original or source page past the video player. Now the detached video disappears and reverts back to the source page when I scroll this control out of view. Is this change intentional and permanent?
