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.

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.

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.

Hi, Since the last update for Mozilla on the laptop (updated on 6/Oct/2025 - version 143.0.4 (64-bit)), all the shortcuts to websites in Firefox homepage I had pinned have disappeared. Also I can't add new shortcuts. I already have shortcuts enabled in Settings>Home>Firefox Home Content>Shortcuts.

Does anyone know how to solve this?

Kind regards.

i looked up lots questions and solution. nothings seems to work. i did all Troubleshoot and diagnose Firefox problems. cleared cache, restarted firefox, refreshed. everything I could do. nothing works.

could you tell me what else I can try?

How do I get searches (my default is Google) to STOP going to the address bar? This started out of the blue and it is making me crazy. I don't want to be asked which search to use, and I don't want it to search in the address bar. I want it in the search box. Thanks.

I'm experiencing problems across numerous sites using the above version of Firefox, detailed below. Other browsers are OK, as are other versions of Firefox on different devices.

Outlook365 email - "Your message can't be displayed right now" Fantasy Premier League - unable to log in, hitting 'Log in' doesn't respond Faceboook - content does not load Ebay - html on formatting in listings is screwed up Duckduckgo non-functional - returns the message "Ugh, it happened again! The server encountered an error and could not complete your request." The Guardian - images do not load Nextdoor - messages do not load

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've tried the "verify integrity" fix and got the results shown in the screenshot below. I've restarted my mac, I've shutdown and started my mac with a hard boot and the icons still show up like globes.

How to make Firefox my default browser on my new computer a Windows 11 computer. I’m to the point where I’ve got a pop-up window, which says sync Firefox on your phone or tablet. I am asked toOpen Firefox on my mobile device. Then Go to the menu and tap sign in. That’s where I am. Now I’m asked to tap “ready to scan” and hold my phone over the code. Unfortunately, my Firefox app does not show a ready to scan option after I get to sign in. Help!!

I am reopening the question from 2020 as the solution described no longer seems to apply. https://support.mozilla.org/en-US/questions/1284577

I am running Windows 11. Firefox 144.0 (64-bit)

When entering search terms into the search bar in the centre of the page, the information typed appears in the address bar, even after following the fix described in 1284577.

Treating the address bar as the search bar appears to be the default. While the user can additionally deselect the search engine in the address bar, that is an unnecessary and undesired additional step for every search (the primary reason I am using Firefox)

Is there a way to permanently set the default for what I enter into the search bar to remain in the search bar and not to be managed by the address bar? Thanks, Rich

Following a recent Firefox update, 1.48.0 I think, the search box in the middle of the page no longer works, any attempt to type there ends up in the address bar. I have tried setting "browser.newtabpage.activity-stream.improvesearch.handoffToAwesomebar" to false and other suggested fixes on the internet but it made no difference. I am running Windows 11 Pro, fully updated. Hope you can help Regards Keith

Mozillers,

I depend heavily in my environmental and other work on Firefox and am grateful for its ability to restore previous tabs when my laptop, not infrequently, stops working abruptly.

Now the much-used bookmarks have disappeared. A search site states promisingly:

"To restore Firefox bookmarks, use the built-in backup feature by going to Menu > Bookmarks > Manage Bookmarks > Import & Backup > Restore, then select a dated backup or a manual file (like a JSON backup) to bring back lost bookmarks..."

But my Firefox's Bookmarks drop-down menu has no Manage Bookmarks option. PLEASE, what must I do?

Elsewhere I managed to find this file which apparently contains recent bookmarks:

"C:\Users\User\AppData\Roaming\Mozilla\Firefox\Profiles\unk14jlv.default-release-1647366062305\bookmarkbackups\bookmarks-2025-12-26_95_4IdGtYxezJpwuH1UIiT1bRwe1K6bcGO8rv0mqa9rUWU=.jsonlz4"

But attempting to open it with Applications\firefox.exe (default) accomplishes nothing.

FOOL-proof instructions would be wonderful. Thank you.

Hi!

What goes wrong with a simple tracking request on the UPS website? Try my actual case with the following link: https://www.ups.com/track?tracknum=1ZA06B736800244687&loc=fi_FI&requester=QUIC%2F/ The response in Finnish is always: "Emme voi suorittaa seurantapyyntöäsi tällä hetkellä. Yritä myöhemmin uudelleen." A quick and dirty translation is: "We cannot execute your request right now. Try again later".

This is an everlasting problem. But try the exactly same link on Chrome or Edge, and it works fine.

Hi,

Since installing the latest FF update (148) a few days ago, I have trouble replying to any topic on this site: https://www.4x4community.co.za/forum/. Prior to this update, there was no problem in replying or posting to the forum.

I do not have this problem on any of the other forums of which I am a member, only this one. I can log in and read posts with no problem, but I cannot reply to any post. I am also unable to start a new post on this particular forum (of which I am a Moderator). There is no flashing cursor when I wish to post, and I also cannot 'copy & paste' a reply either.

I have disabled Malware Bytes, Dark Reader and AdBlock plug-ins, this makes no difference.

If, however, I run FF in the "Troubleshoot" mode, I am able to to post replies to this forum. I have reinstalled FF v148 twice, the issue remains.

Testing the same forum with Opera browser I can access and reply to the forum above, even though with Opera I use the same plug-ins mentioned above turned on. It appears to thus be a FF permissions issue. I have cleared my Cookies and cache but this did not help.

Do you have any other suggestions? I am a FF user from day 1 all those years ago and have no desire to change to another browser.

Regards, Eric
