Diễn đàn hỗ trợ Firefox

I tried to reach the following adress: https://www.itu.int/harmful-interference-to-rnss/ and I received this message on my browser: 400 Bad Request -Request Header Or Cookie Too Large

When I tried from a different browser it was accessible.

So i've lost access to my email on. my old mozilla accounts and upon logging in on a new device im being asked for a code to the email which i don't have access to anymore is there a way that my info can be synced to a new one. Thanks

McFee is trying to sell us computer protection. We have had Firefox for several years. I am now getting an alert to Turn On Firefox. How would it get turned off, and how do I turn it on without going through Mozilla's selling site?

8 out of 10 times that i try to connect to the following site:

https://www.tax.ny.gov/online/

I get the following error message:

Secure Connection Failed

An error occurred during a connection to otc.tax.ny.gov. PR_CONNECT_RESET_ERROR

Error code: PR_CONNECT_RESET_ERROR

   Please contact the website owners to inform them of this problem.

Now and then, I'm able to log in successfully. lately though, I'm having trouble logging in using Firefox browser.

This is becoming very frustrating. What could be the issue? What do i need to do to resolve the problem?

I am interested in Firefox View, but I do not see that button on my toolbar (see attached image). When I search extensions I don't see that come up as an option. How do I add Firefox View?
