Firefox started blocking Elctronics Distributer www.mouser.com that I need to access

1of8billion

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?

I thought I had checked for typos before posting but I see I missed several.

I saw an article about private browsing and tried that. Firefox had no problem going mouser's site in private mode. Regular browser mode still won't get there, but at least I can now order my parts without resorting to Edge.

I would still love to know what happened that keeps Firefox from showing www.mouser.com
