Diễn đàn hỗ trợ Firefox

.: Hello. A couple of days ago Firefox stopped displaying thumbnails of YouTube videos. I tried YouTube on other browsers and the thumbnails appeared as usual. On Firefox, they've disappeared, but only on my Windows 10 computer. The YouTube thumbnails appear on Firefox on my MacBook. The attached graphic shows what it looks like on my Win 10 computer.

Any ideas on how to solve this would be greatly appreciated. I have also searched the Internet and YouTube for a solution, but was unable to find one that works.

Thank you.

Lately , when accessing some sites , I have been getting a blank screen with a video ad for Pandora Jewelry in the upper left corner. It takes over the tab a few seconds after opening the site. Does not seem to affect most sites (yet). Did a virus scan and a Malwarebytes scan. Both came up clean. Cookies and cache were deleted and the system rebooted. No luck. Tried restarting FF without extensions with the same results. The screen does not allow a screen shot.

Anyone else seeing this? Any clues? I am using Windows 11 Pro.

I've been using Firefox on Mac and PC for many years, and been on Twitter/X for 12 years. Never had a problem before this.

X is now requiring users to enter and verify a 4-digit passcode to be able to use the DM feature. Firefox on Mac won't let me do this. Every time it produces an error message:

"Unable to load encryption module. Please refresh the page and try again."

But when I do it in Safari, or Explorer, or Chrome, it lets me do so.

The problem is, most of my data and resources are on my Macbook, and I have not been able to find a workaround. I've cleared my cache, made sure I'm on the latest version of Firefox, restarted it several times - same thing.

I need to get this fixed. Please help.

I am having trouble accessing The Washington Times with Firefox. Every time I click on a story, it comes up, but then immediately the screen shades out to a gray screen, and nothing works. Also, if I open The Times website and click on sign-in for my account, nothing happens. If I go directly to the Times website and try ti sign in, the screen greys out again. This just started happening yesterday. If I go to a laptop with an earlier version of Firefox on it, all works just fine. Also, if I access the Washington Times with Microsoft Edge, it works just fine. Would appreciate it if I could get some help here.

I am not able to access my emails in Yahoo Mail. Can't even send emails. Tried accessing Yahoo Mail using Chrome and did not encounter any accessibility problems.

Youtube does not work. It shows somekind of default page that is essentially blank. It does say: "Try searching to get started" and "Start watching videos to help us build a feed of videos you'll love."

But it will not respond when I attempt to search anything.

05/20/2025 twitch streams stopped working, image disappeared, sound is there. Also working videos that are on twitch, not streaming. In windows 10 everything works.

All of a sudden I cannot log into my amazon.com account on firefox??? This does not happen with Chrome or Safari. When I try logging in firefox freezes and I have to quit the application and restart.

I've been unable to sign in or send messages through certain sites. Put Firefox in troubleshooting mode and everything seems to be working correctly. How can you tell what settings need to be changed to keep it working correctly? Or should I just leave the browser in troubleshooting mode? Thanks. Jim

When I go to YouTube to watch videos the Vid's always stop after a short time. The refresh page and back buttons do not work and neither does the ability to click on any links on the page. I have to close the tab and start again. The issues still occur on new tabs. Eventually I have to close FireFox altogether but when I try to open FireFox again it does not work or takes a few minutes and sometimes the message Firefox is still running. At times I have had the sound of the videos, when they do play, from YouTube still playing even when the browser is closed.

I am having problems with Firefox not scrolling (and no scroll bar) on some web pages. The following is an examble:

Two QNAP NAS displayed readable web pages this morning. Early afternoon I updated Firefox with a reset and the admin pages on both servers are unusable. How can I roll back Firefox or recover the earlier version?
