Diễn đàn hỗ trợ Firefox

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.

upon opening firefox the following address appears in the search window:

https://eventseekspot.com/?path=firefox/newtab&u=864940da25d1ae22&subid=11119&channel=1

why? and how do i make it go away

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.

Trying to access search Home Depot, Lowes, Tractor Supply gives errors. Works with Chrome. Started about 2 weeks ago or so. I use Starlink, no VPN, tried disabling Ad Blocker, Clearing cache for Lowes, no Add ons, but still doesn't help.

Error msg from Tractor Supply is: Access Denied You don't have permission to access "http://www.tractorsupply.com/tsc/catalog/lawn-garden?" on this server.

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.

Since the last update, the firefox taskbar icon is showing a strange shopping card icon? How can I remove it? I am not shopping with Firefox, I am using it as my web browser.

I was going through my account settings today and noticed that two factor was disabled. I thought this odd as I usually set it up on any account I use, so I of course turned it on and went about linking my authenticator app and generating account recovery codes. Yet in my authenticator app there was already a Mozilla account with my email, but the codes it supplied did not work. I also found old account recovery codes I had written down which did not work either.

What could have happened to cause this? I must have had two factor on sometime in the past and added it to my app and generated recovery codes. How could it have been disabled, the old codes made invalid, and Microsoft authenticator unlinked? Am I looking at an account breach somehow? I have no unusual activity as far as I can tell and no recent data or password breaches. The only thing I can think of was I removed a number of old devices from my account and signed out of them, but I still own the old PC's so no one could be using them.

When I inadvertently press CTRL + R when entering text, it is VERY frustrating because the window refreshed and I loose all of what I typed! Is there some way to disable the CTRL + R combo so the window does not refresh?

Thanks

Bonjour en voulant aller sur un site connu et auxquels je vais j'ai eut ce message je n'ai rien modifié sur mon ordi d’où cela viens t-il et surtout comment y remédier. Merci "Pourquoi ce blocage ? Quelque chose dans le comportement du navigateur nous a intrigué.

Diverses possibilités:

Des difficultés pour accéder au site ?"

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?

Examples of webpages I've entered today that receive an error message are https://leafscape.com & Mint Mobile

Sometime ago I must have made a typo when entering my email address into a pop-up window in Firefox. Firefox continues to find and use this wrong address in pre-fills but I can't find anyway to correct it. I've worked through Settings/Privacy & Security with no luck. Can someone help please? (Windows 10 Firefox 145.02)

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!

System: Fedora 42 (Workstation Edition) Running Firefox 144.0.2 on Gnome 48.6-1.fc42

I updated Firefox to 145.0 this morning, and after Firefox had restarted, it had lost all bookmarks and the bookmarks toolbar. I have spent all day following links to correct the problem and got nowhere. I have restarted Windows and Firefox countless times - no change. I've even tried reinstalling Firefox over the existing version. If I go to bookmarks > manage bookmarks > restore and backup, sometimes that will load, others not. When it does load, it fails to find a file to restore from. 10 years of bookmarks, links & research vanished.

Can someone please provide a solution (preferably in Layman's terms) to this??

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.

I've searched other forums and I am not having any luck. If I open 1 Firefox browser then 10-15 open instances will show up under Task Manager. They load automatically. This slows down everything and I have to delete the excess browsers. Would you please offer some advice? Thank you in advance.
