Diễn đàn hỗ trợ Firefox

I am running Windows 10 Enterprise version on my desktop.

The same video on Facebook plays perfectly on Chrome but the sound is muted when it is played on Firefox. It happens only recently.

Is there some control features that I should turn on or turn off somewhere so that I can continue to use Facebook a usual on my Desk top.

Running on an M1 Ultra Mac Studio, Firefox struggles to play 4K videos in recent days where it would've normally performed fine. I've never had troubles watching 4K YouTube on Firefox, until the past week or two. There are no other applications running, and only the one tab open in Firefox. Just a regular 4K video. Why won't it play properly? Why does it start buffering randomly when I can see my network is just fine? Why does it just randomly skip 10 seconds every minute or so while playing? This exclusively happens on 1440p or 2160p (4K). Please fix this ASAP.

Hi, Mozilla Relay/mask is connected to an old, defunct email address. How do I change that? The verifications are going to the old address that I can no longer access.

Dear Sir or Madame,

Read Aloud isn't working on Roshreview.com and other websites for my new macbook on Firefox but works on my old macbook.

It says "Missing host permissions for the tab"

Hi, Moz://a Support Team

I hope you're doing well,

I'm encountering a problem accessing the Moz://a website due to a persistent pop-up error message. Could you please assist me in resolving this issue?

Any guidance or assistance you can provide would be greatly appreciated.

Thank you for your help.

Best regards, Karlie

Microsoft crashed and rebooted my computer. I restarted Firefox and can't access anything in the hamburger menu. Nothing happens when you hover over it, right click it. It's a dead stack of lines.

I manually navigated to Mozilla support and that works. Google search window works. I am signed in and see my name at the top. No menu; can't get any of my history.

What would cause websites not responding. I have no malware and the cache is clean. Could it be in the properties, or whatever.

Thank you. It's very frustrating.

I have recently (today) installed a device (Mini Wireless USB adapter) on my desktop computer. I am now connected to my ISP modem wirelessly. I have been using Firefox as my browser for many years (ten?) and have not had a problem until today. When I attempt to go to a web site I get a notice that says: "Unable to find the proxy server. Firefox is configured to use a proxy server that can't be found. Check the proxy settings to sure they are correct. Check to make sure your computer has a working network connection. If your computer or network is protected by firewall or proxy make sure that Firefox is permitted to access the web."

I am able to get to any web site I choose when using another browser. I am also receiving my emails, and able to send emails. So I know the computer has a working network connection. When I have visited the Mozilla support site (having to use another browser) I see advice that shows opening the Settings page and getting to the Proxy settings. When I open my "Settings" page from the menu on the Firefox home page upper banner I do not see any option to get the Proxy settings. How do I access the Proxy settings page? Or how do I access the Firewall settings? Don't forget, I cannot open any web page from Firefox.

I always have the latest version of Firefox today it is 120.0.1

I get several of these and I have Bitdefender antivirus

What to do ?

I just had to clean install Firefox after having problems. I've pretty much set it up how I want it, except when I quit Firefox and then re-open it all the tabs come back. Which I don't want. The box in the settings page for opening with previous session is unchecked. What else am I missing? I re-started my computer just in case that was an issue but the problem continues. Thanks

Website fonts are often garbled. See attached screenshot. I've tried the other suggestions mentioned here but nothing changes; it's still happening. I'm on a 2020 iMac with a 3.3 GHz 6-Core Intel Core i5 processor with Mac OS 14.1.1 and Firefox 120.0 (64-bit).

Help?
