Firefox shows an highlighted shield icon at the left end of the location/address bar in case Tracking Protection is blocking content.

• click the shield icon for more details and possibly disable the protection

You can check in the Web Console what content is blocked.

Are you using the Password Manager to enter a saved password automatically or are you typing the password ?

Hi,I have Tried using Password Manager (that does not Work) & therefore I use my Password by Typing it in,But That goes no where & then I have to hit Reload Current Page & that States it needs to be resent & then It comes up with the Log in details & states the Password is incorrect(sorry to put it this way (BULLSHIT) Between Yesterday & today,I have reset that many passwords,it is not funny anymore & I am running out of passwords Firefox is the PROBLEM,if I cannot Fix it(with your help) I will give Firefox the Flick,it has cost me many many,many Hours & Frustration is not the word for it

Thanks Darryl Darryl

Hello Darryl,

"If you can't remember your pasword or it's not working" :

https://support.microsoft.com/en-us/help/12429/microsoft-account-cant-sign-in

Anything helpful there ?

I'm a little worried about you saying :

"I just had Microsoft into my Computers" ......

Could you elaborate about that please ?

It is very long & involved,a very short version,I have had to have at least 10-12 Windows 10 downloaded with Microsoft,the Last on Friday,It was a TOTAL RESET of my Computer & I lost Every thing &(apart from the new windows 10) due to a few Problems I could not resolve my self,I rang Microsoft & they came into my Computer & rectified about 3 or 4 settings & fixed the problem with my Printer Whilst they where in their,I pointed out to them about the Problem that I could not respond to Microsoft Community (through FIREFOX) & they went through with Bing & their was no Problem & they Pointed out it was a PROBLEM WITH FIREFOX) Firefox to me at the moment is a PAIN IN THE Arse & the way it is going,I WILL GIVE IT THE FLICK I have WASTED THAT MANY HOURS ON IT,but Nothing Works & to me that is USELESS Darryl

I forgot to mention,what you Hi Lighted about Password on Microsoft,is totally wrong,especially when I can log in when I use BING,which PROVES IT IS FIREFOX CREATING THE PROBLEMS Darryl

Bing is not a browser though; it's a search engine (like Google Search).

Microsoft's default browser is either Edge or Internet Explorer - as you mention the latter a few times, that will probably be the browser you use to login.

May I ask : When you click on the 3-bar menu => Options => Privacy & Security; under "Logins and Passwords" - is the box "Ask to save logins and passwords for websites" checked ?

Yes it is, I do not alter anything in the settings in Firefox,the only way they are altered is when Firefox does a update Darryl

Would you please check to see if that box is ticked anyway ?

Would you also check in 3-bar menu => Logins and Passwords, "login.live.com" is listed ?

(they say the internet makes your life easier - isn't always true, is it ?)

HI,Login.live.com is listed BUT (No Username) & Password is Correct I altered it to(username) to my email address(the same as you are using) & saved I will try it tomorrow to see if it works Tired,Sick of Computers,spent at least 9 hours on it to day & my Eyes are getting Square Thanks Darryl
