After the latest Firefox update, I could run YouTube without problems for several weeks. Now YouTube will not run. How do I fix this issue? I suspect it is due to an adblocker but not sure!!

After updated to Firefox 140.0.4 (20250707120347), all site do not load for me, general sites, like youtube/google. There's nothing wrong with my Wifi/Internet Connection, even Microsoft Edge can load the websites.

I'm unable to log into my social security account when using firefox. Have no trouble with safari.

I get the following when using firefox:

400 Bad Request Your browser sent a request that this server could not understand. Size of a request header field exceeds server limit.

Hello and sure hope someone can help me. Fire Fox is my browser that I have had for a year or so. Pls understand that I am 80+ and am not as sharp as I once was. I am using a desk top that I have had for years. Several days ago I was on the web looking around. I don't remember where I was on the net but I am thinking it was Face Book. Anyway, up came this offer saying I could create a new profile and a new name on Face Book if I wanted to. I have always wanted to do that so I started filling out the paper work. I made up a profile name and a user name and was moving on to the next part when it came to me that this might be a scam, so I canceled what I was doing, or tried to. Boxes kept coming up telling me that I needed to finish filling out the form, but I X'd out of that too, several times. Then the box said "you need to finish filling this out or you will never hear from us again. Then I shut the desk top down until the next morning. In the am, I went on Fire Fox and went to the Face Book site. For awhile all I got was pretty much a blank page with no way to do anything. A day later the sight came up kinda but things were a bit different. There were some things like my profile picture at the top rightwas gone and then Boxes were coming up telling me to complete the paper work I had started. By this time I knew that someone was trying to scam me. I tried to find several sites that were generally on my home page of Facebook when I signed in, but they were gone now along with other things. I went on two another browser and got on Facebook and found things to be very normal, so what ever happened only effects the Fire Fox browser. I would sure like to fix this so I could use Fire Fox to connect with Facebook. Any help would be appreciated. Thank you for taking the time to read this.

I have loaded Messenger onto my new computer as well as Firefox. When I go to Messenger the Voice and Video icons at the top right are greyed and when hovering over the icons, I get a message that video calling etc is not supported. i had no trouble on my other computer but am not sure how to activate the video and voice options. Can you please help me solve this issue. Thank you

I am using Firefox on Win 11, recently I have noticed a weird problem, on Ebay for example when a listing uses a drop down selection box for sizes, amounts etc none of them work for me, I click on the box and down arrow but nothing. I also went on to the Vodafone site to top up my phone but I was unable to do it as the drop down box to select the amount was empty. I have tried clearing my cache and even reloading Firefox but nothing seems to work, I just tried using Edge as well but its the same, suggesting that its maybe something to do with my settings?

Starting this morning Firefox is not letting me log in to some pages. Other pages i can get into but they do not display/load properly. Everything was working fine on Friday. What changed?

What in the actual hell is going on? Since when did this become a problem? Website ends with .to instead of .com but this has literally never caused me any problems on this machine and I've been using the same extensions/add-ons since I bought it. It's been at least 3-4 years. Windows 11 24H2 (latest update) Firefox Version 140.0.2 (latest update) No settings have been changed, aside from my updating the browser and/or my operating system. Please help.

Website if that even matters. https://1337x.to
