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:

why? and how do i make it go away

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.

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.

The latest version of Firefox appears to have updated a setting: When selecting a custom search engine in the address bar or search box, you now need to click the mouse three times (click the dropdown button on the left side of the box - select search engine - search); previously, after entering search terms in the search box, you only needed to move the mouse icon below the box to automatically display all search engines, and then click the desired engine to search directly, thus completing the search with just one click.

The old setting was very convenient; while the new setting forces me to click several times every time I want to search for a term in the search bar.

I hope the support team will address and improve this issue.

On new tab, all my added short cuts are gone and it doesn't let me add any. For example I want to have a shortcut to say... Amazon, but when I type or paste in the url, it still doesn't add it and the add button goes blue, not white. I have the shortcut feature turned on

I have emptied cache, reset everything and I still get

This is from Cabelas.com but I am getting it more and more from other web sites. American Airlines, Delta.com, etc. I accessed the help and did all the steps about fingerprinting and turning off "enhanced tracking protection" and nothing helps. Any ideas? Don't like the idea of using Chrome or Edge, but Firefox is almost unusable for me now. If I have to keep using another browser for the sites, may as well just use that one only.

when i attempted to log into gmail today using firefox i got a screen touting their new ai stuff and requiring me to sign back into gmail. after i entered my email, it asked me to sign in with my passkey and froze. this happened three times. i restarted everything, no joy. could only enter through chrome. then about 12 hrs later i was able to enter via firefox. who knows why. i am not a computer tech person. problem is solved by the invisible hand. some tech person replied to my inquiry with the super unhelpful “i don’t have that problem.” good for you! couldn’t get back to the conversation thread to say, problem solved.

All my bookmarks disappeared and the bookmark button does not work. I have refreshed Firefox - no change. I have uninstalled and reinstalled Firefox but still no restoration of Bookmark button functionality. OS Win10

I am running Firefox 144.0 on kubuntu 24.04.3 LTS I have lost sound on Firefox. I have opened the same sites in Chrome and the sound is working fine. It's only in Firefox. I have tried several sites including Udemy, YouTube, and radio programs, no sound from Firefox. The problem started in the middle of a Jit.Si session. All of a sudden the sound disappeared. I thought that restart Firefox would help, then restart the computer would help. But the problem has continued. The speakers is turned on the volume is up, just not a sound from Firefox. What to do?

Started a few days ago, I'm getting a Access Denied error on Sky News web site-:

Access Denied You don't have permission to access "http://news.sky.com/uk" on this server. Reference #18.6e3f655f.1775840716.11cf0872 https://errors.edgesuite.net/18.6e3f655f.1775840716.11cf0872

Has anyone a clue? I can go to the Sky Watch live..... when I click any link I get the same result above. This happens when running Firefox in safe-mode.

Running Win 7 x64 115.33.0ESR This is the only problem I have.

I have a GPO policy that sets Homepage for startup to open specific URL, and now it just stopped working after last update to version 149, instead i get standard FF startpage.

- tried updating .admx templates to the newest version

- about:policies shows correctly that GPO is enforced

Everything checks out but somehow it is not working anymore. Someone with similar problem?

Firefox comes up in a large window, covering most of my screen. I can resize the browser window just fine, as expected. However when I close the program, then open it later, the browser window is not the size and position it was in when I stopped the program last, it comes up with a large window again.

Firefox has been my browser of choice for well over 20 years. I have a game I play every day (from FaceBook) just this week when I try to go to it on my laptop - it says your browser does not support WebGL. it has always opened using Firefox - this is a new error message. and the computer is only 5 months old and has Windows 11 on it. I do not want to switch to Google or Edge.

Like I said - opening the app worked every day up until about a week ago. What gives?

I'm trying to stop Firefox from restoring tabs after I restart my OS. So far, I've done the following:

• Disabled `Startup > Open Previous Windows and Tabs`
• Disabled all extensions
• Confirmed I do not have a `user.js` file
• Set `browser.sessionstore.resume_from_crash` to `false`
• Set `browser.sessionstore.restore_on_demand` to `false`
• Set `browser.sessionstore.resuming_after_os_restart` to `false` (It was already set this way.)
• Set `browser.sessionstore.max_resumed_crashes` to `0`
• Set `privacy.clearOnShutdown.openWindows` to `true`
• Set `browser.sessionstore.max_tabs_undo` to `0`
• Set `browser.sessionstore.max_windows_undo` to `0`

(I've since reverted the last two and the extension changes after they didn't work.)

So far, Firefox will not restore tabs on application restart (manually closing and relaunching) or on crashing (after sending SIGTERM/SIGKILL), but it still restores tabs after restarting the OS (if I allow the OS to kill it during shutdown). I've seen a couple suggestions to disable history completely, but I do occasionally refer to my browsing history, so I'd prefer a less-drastic approach. Ideally, I just want Firefox to treat the first launch after a shutdown as a normal launch and not apply any special behavior. Any help would be much appreciated!

When I try to make a Google search I get the following message, "I'm not a robot" with a reCAPTCHA: "Our systems have detected unusual traffic from your computer network. This page checks to see if it's really you sending the requests, and not a robot. Why did this happen?". This happens on Firefox, but not Chrome or Edge. If I 'Allow' Google in the 'Exceptions - Cookies and Site Data' then I do not get the message, but it takes several seconds for Google display the resulting page. However, if I delete the cookies/cache the message will return and I have to redo the reCAPTCHA. I have scanned with Malwarebytes, Bitdefender, Hitman Pro, Trend Micro House Call and Microsoft Defender, nothing detected. Running Win 10 (64) with 'Extended Security Updates', Firefox 147.0 (64), no additional Extensions or Plugins. Also I uninstalled and reinstalled Firefox.

Recently several sites, including Zoom.us and Genesis.com, no longer work in Firefox on my PC running Windows 11. For example, when I log into Zoom spinning wheel indicating the system is working keeps spinning and never lets me enter my password. Yet if I use Edge everything works as it should. I really want to be able to keep using Firefox as my default browser.
