Within the past week (beginning of Novermber 2026) firefix has started blocking my access to an electronics component distributer that I have used for well over 20 years. www.mouser.com

I need to get to the site to order some parts but cannot get there. Microsoft's Edge browser gets to the site without a problem but in firefox, I get only the following:

Quote: The connection was reset

Firefox can’t connect to the server at www.mouser.com What can you do about it?

   The site could be temporarily unavailable or too busy. Try again in a few moments.
   If you are unable to load any pages, check your computer’s network connection.
   If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the web.

End-Quote

Even though the Edge browser opens it, I prefer not to use Edge due to it's intrusive nature.

This has only started happening this week. I updated firefox but I still can't access www.mouser.com.

So far, this is the ONLY site I have been unable to get to. And again, this behavior started just in this past week.

Why is firefox blocking my access to a legitimate business?

This puts me a bit at risk converning a controlled password, on the ither hand this is a very safe way to connect for exanple, using standalone logging features require additiinal passwords or oher forms of fraud

So many damn restrictions. i can't browse anything without getting blocked. why the hell did i move from chrome. I dislike this browser as it is blocking almost all access to my local government websites. including many others.

I can't find any settings to fix this. if i don't solve this within this couple of hours. I'm deleting this crap

Sorry for the anger. but wasn't Firefox supposed to be USER FRIENDLY? because at the current the state it is moving FAR AWAY FORM THAT.

Hello Mozilla Support,

I have been using Firefox's built-in VPN successfully for some time, but it has suddenly stopped working and now displays this message:

"VPN is unavailable – Local laws and restrictions limit where you can use VPN."

Could you please clarify whether this is due to regional restrictions or sanctions, and whether there is any possibility of restoring access?

Thank you for your assistance.

I'm interested in learning how to identify and resolve website loading problems when using Mozilla Firefox. While reviewing the website for Sloan Bail Bonding (sloanbailbonding.com/), I wanted to understand what factors can affect how quickly and correctly a website loads in different browsing environments.

Sometimes websites may take longer to open, display incomplete content, or stop responding as expected. These issues can be related to browser settings, extensions, network connections, cached data, or other technical factors. I'd like to learn how Firefox handles these situations and what steps users can take to identify the actual cause of a loading problem.

Are there any built-in Firefox troubleshooting tools or recommended methods for diagnosing slow page loading, connection interruptions, or pages that do not display properly? I'd appreciate practical suggestions for checking browser settings, testing extensions, and improving the overall browsing experience without unnecessarily changing important security or privacy settings.

Recently, i saw an ad for Firefox that said that now you guys have your own VPN, i downloaded it on my phone and it works just fine. Seeing that, i decided to use it on my PC too (Windows 11), that had Firefox installed but it wasnt being used. I logged in with the same account from my phone and did all the steps to set everything up, but the option to use the VPN just isnt there. I looked up what that could be but after following every step given, it seems everything is in order for it to work but it doesnt. My firefox is updated, im not part of any studies, my country is included in the VPN stuff, and theres no configuration stopping it from being able to work, so i dont understand whats going on. Ive used other VPNs on this PC a few times and it works. This is a bummer because the VPN was the only thing drawing me to this browser and this feature was marketed a lot on social media.

Getting Recaptcha msgs when trying to use Google search on Firefox desktop. Happening on 3 laptops with different users. Tried all recommended fixes. Nothing worked. Recaptcha references IP issues. Had Verizon change the IP address several times. Nothing worked. Note: Recaptcha issue goes away in the computer store (with a different ISP.) Help! Please.

The topic that best describes my question is "Appearance", but I don't see that topic in the dropdown. Firefox 159.0.1. I have Firefox adhere to "system colors". The current tab title has a white background, the others blue. With an older version of Firefox, the text in the tab title was black if the background was white. With version 159.0.1, the current tab title uses white text if the background is white, making it unreadable. See images with red arrow pointing to what I'm talking about. The first 2 images show the new Firefox, 159.0.1. The 3rd image shows an older version, that properly adjusted the text color to black, if the tab title area was white.

I DON'T KNOW WHAT MOZILLA HAS TO DO WITH FIREFOX TO GET THE USERNAME TO BE ENTERED IN THESE TWO WEBSITES, BUT IT'S BEEN TOO LONG THAT IT STILL DOESN'T FILL IN THE USERNAME ON SUCH POPULAR WEBSITES.
