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.

Hi, When I want to open and see most of sites, this extension show me the pop up and message:

Ads Blocker Detected!!!

When I click on the search box in the middle of the New Tab page and start typing, the focus automatically jumps to the Address Bar (Awesomebar). I want the typing to stay within the central search field.

In about:config, I have set browser.newtabpage.activity-stream.improvesearch.handoffToAwesomebar to false. However, this did not fix the problem — the input is still being redirected to the top address bar.

My Hoepage is set to Firefox. In the center of that page is a Search box which I used always. Now when I try to type in it, my cursor shoots up to the top to the ADDRESS bar. I do NOT want to SEARCH from the address bar. I want to search in the Firefox search box. I also have Duckduckgo set up in that search bar. After the last 2 Firefox updates, I can no longer type my search in that box, but can ONLY search in the ADDRESS bar. Please help be restore the use of the Firefox Search box.

Hi All,

I would like to remove the first item from the Tab Context Menu, which is "Add Tab to New Group", and simply have "Reload Tab" as the first menu item.

I was using this code, which worked in FF 145, until the latest update (FF 147)...

#context_openANewTab,
#context_moveTabToNewGroup,
#context_moveTabToGroup,
#context_ungroupTab + menuseparator {
   display: none !important;
}

However, now there is an extra separator line at the top of the menu (see attached images).

This code also removes the top menu item, but still leaves the separator line on top:

#tabContextMenu #context_moveTabToNewGroup {
  display: none !important;
}

Is there a way to remove the first menu item without adding the separator line?

Thanks!

Firefox updated automatically overnight, all bookmarks vanished. Toolbar bookmarks, gone. History information disappeared two weeks ago. Library box is now gone, too! Windows 11. Firefox version 147.0.3 64-bit

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.

I have been having trouble with my Windows 11 laptop. In my efforts to resolve these issues I noticed that I now have two installs of Firefox in my Control Panel. Both installed during my time of dealing with my Windows issue. Five days apart Feb 5 and 10, 2026. Both show the same version number 147.0.3, and same size 322MB. I have used FF for many years so these seem to have been installed sometime during my efforts to repair Windows. My FF was never a part of the Windows issue AFAIK.

Anyway I have FF working as I like with my Session Manager and various AddOns and personal settings, so I do not want to have to start over with FF. So how do I choose which instance of FF to uninstall in Control Panel?

My issue with Windows was my Outlook would not connect to the server. I assume Microsoft Exchange server, my internet connectivity was fine. And FF was fne as well. I eventually was able to repair my M365 connectivity. Major PITA from out of nowhere.

I have finished my setup. But it keeps saying "finish setup" in the upper right corner of the browser. I have completed all the steps. I want to sync this desktop to my mozilla account. What do I do?

Hello.

My Firefox account ([email removed]@gmail.com) was automatically blocked because the confirmation email was returned.

I did not violate any rules and I have access to this email address.

Please review my account and help me restore access.

Thank you.

My machine runs Windows 7 (will not change) and Firefox version 115.32.1esr (64-bit). Until a few days ago, weather.com worked as expected. However, when I try accessing it now (with a specific location), the screen indicates: Application error: a client-side exception has occurred while loading weather.com (see the browser console for more information).

The following is from the browser console: [Experiment] Fetch all: retry=false [Experiment] Fetch variants for user: Object { library: "experiment-js-client/1.16.2", language: "en-US", platform: "Web", os: "Firefox 131", device_model: "Windows", device_category: "desktop", referring_url: "", browser: "Firefox", landing_url: "https://weather.com/weather/tenday/l/Ann+Arbor+MI?canonicalCityId=3c1740550b2f113b86f9cd665770bcf3e3e1a34bf7ac0189a6e3d215540792e7", first_seen: "1770396676.778", … } Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://api.lab.amplitude.com/sdk/v2/vardata?v=0.

What the bleep is going on and how can this be resolved? Note that the site works just fine when using a Chrome-like browser.

Firefox stores certain temporary data in a startup cache to improve startup speed. Clearing the startup cache and then restarting Firefox can sometimes fix various issues, such as mixed languages in the user interface after an update. This will not change your profile data or add-ons.

You say to go to the download page and my version of Windows will be detected & you'll give me the correct version. However, IE 8 in Windows 7 won't go to your download page. So, I need to download from another computer and copy the file to the Windows 7 computer. This doesn't work when you detect that the computer doing the download is a newer computer. How do I tell your system to give me the Windows 7 installer?

normally i just click the forefox icon on my taskbar and type claude.ai in the address field but today i was messaged that the claude program needed a mozila account - so I had to set one up. why and still cannot get to Claude

All of a sudden, my default search engine changed to Google. I didn't do it and don't want it. The "settings" still show Firefox as my default, but it doesn't stop Google from hijacking my searches. I want to get rid of it.

I previously had a Firefox account registered with my original email address. Recently, I changed the account’s primary email by adding a secondary email address, switching it to become the primary email, and then removing the secondary email address.

After completing this change, I attempted to create a new Firefox account using the original email address that was previously associated with my account. However, during the sign-up process, I receive the error message: "Primary account email required for sign-in."

It appears that the original email address may still be linked to the previous account in some way, preventing it from being used to register a new account. I would like to understand why this is happening and how I can free the email address so it can be used to create a new Firefox account.
