Firefox Community Forum

I've disabled all of my addons, cleared cache, and still youtube is broken for me. It works fine with Chrome still. Any ideas on how to fix? See attched screenshot.

All Add-ons are disabled and Firefox still can not play SOME of the videos on twitter. All I can see is a spinning circle on the center of the frame and the video will never be played. I tried other browsers and they all works well. It seems this issue has nothing to do with my network connection.

I searched this forum and find out some thread reporting issues of not playing All videos on youtube/twitter. Replies to these thread provided some solutions ,like update ffmpeg , set media related options in about:config. I tried them all and neither of them work for me.

Firefox will not allow me to login to my mail a/c which I have had for more than 20 years. Because of this I cannot access a code to access my MS Outlook a/c This message shows:

'Firefox detected a potential security threat and did not continue to webmail.mercuryin.es. If you visit this site, attackers could try to steal information like your passwords, emails, or credit card details.' AND tells me that there is nothing I can do about this.

I have used Firefox for years and had AVG free antivirus installed also for years. Tonight I had a popup window open from AVG informing me that AVG no longer support Firefox and have uninstalled their antivirus addon with immediate effect.

Does anyone know of a Free antivirus program that is any good and still supports Firefox?

In recent attempts to join a few webinars I am now getting more and more "TLS Errors." I have noticed that many of the solutions to this problem involve actions that do not solve the problem but create larger issues. Do you have a solution that works safely? I am forced to use Windows 7 unfortunately due to work systems and a long story. I think this is my primary problem but I have to keep using it until the bitter end with this PC.

I appreciate your kind help. Thanks, Clay

It looks as though installing this 115.10 ESR will be a "new Install" instead of an update.

1) Will I lose my bookmarks, settings, passwords, ect? (My bookmarks have been collecting for years....)

2) If I try this will creating a restore point return me back to the way I was before the attempt?

Thank You All!

My Firefox browser recently updated to 115.11.0esr (64-bit), and now embedded videos won't play, I can initially see a picture, but instead of starting to play, the screen turns dark green and I can only hear the sound. This happened once before recently, but then it seemed to fix itself after a week or two. How can this be fixed?

Secure connection failed and Firefox did not connect Firefox Last updated: 01/16/2024 39% of users voted this helpful

This article explains why you may see a Secure Connection Failed or a Did Not Connect: Potential Security Issue error page, and what you can do.

   If you see a Warning: Potential Security Risk Ahead error page, see What do the security warning codes mean? and How to troubleshoot security error codes on secure websites.
   To troubleshoot other error messages, see Websites don't load - troubleshoot and fix error messages.

Secure connection cannot be established

When a website that requires a secure (HTTPS) connection tries to secure communication with your computer, Firefox cross-checks this attempt to make sure that the website certificate and the connection method are actually secure. If Firefox cannot establish a secure connection, it will display a Secure Connection Failed or Did Not Connect: Potential Security Issue error page. Secure Connection Failed

A Secure Connection Failed error page will include a description of the error and a Try Again button. There is no option to add a security exception to bypass this type of error.

Lest update to 15.9 all my extensions are now disabled. Missing Lastpass and Surfshark from my menu bar. Doesn't seem to be any way to Enable them from Extensions screen.

I reloaded Lastpass from their site and this is now working on my Menu bar.

But what happened to cause this

McAfee malware has entered the firefox browser a couple of days ago claiming viruses have been detected & requires me to click on their popup to remove it. Additional warning follow and reoccur every couple of minutes. I don’t have McAfee Anti-virus software on my computer & have not installed any new software for some time. The anti-software I have works fine (Spybot & Microsoft Security Essentials) and detects no problems. The first application I initiate upon boot-up each morning is Firefox and that’s when the problem begins. It is somehow related to Firefox. I cannot find any processes in play.

I can open Chrome with no problems (however, Chrome no longer supports Windows 7. I’m using Windows 7 Pro. I tried all the free malware scanning programs suggested but nothing found.

I cannot find any link to Firefox Desktop Support as you suggested. Can you please forward this email to that support team.

Sincerely, [removed email and phone# from public support forum], Florida

After the browser update earlier today I cannot log into 'You Tube TV'. The browser keeps asking for my email and password over and over and never signs me in. It keeps telling that I am signed out and need to sign in, over and over. I cleared my cache and cookies. I changed my sign in from my yahoo email to my gmail account and it still will not work. If I use the chrome browser it works fine. Please Help.

best regards,

Comments on YouTube videos are no longer visible after Firefox version 115.10esr update. They do however work on my other computer which also has Firefox but not an esr version since it has a more current version of windows. I tried deleting all cookies and cache, starting in safe mode, disabling ad-blocking on YouTube but nothing worked. I'm thinking of rolling back to the previous update but would rather have this problem fixed.
