Firefox Community Forum

Today, when I logged onto my computer, something went wrong and Windows had to repair my C: drive before it could continue to boot up. Once it did, Firefox was changed. Some of the shortcuts on the windows were missing and I couldn't get them back with the command to "Dismiss" the substitutes. More serious was my new inability to log onto any sites besides Mozilla's. I have tried restarting the computer and turning off my router and turning it back on again. All the while, my Android phone account is able to login to some of these sites without difficulty. I need to diagnose this problem and fix it. How can I do that, please?

If you entered the right address, you can:

   Try again later
   Check your network connection
   Check that Firefox has permission to access the web (you might be connected but behind a firewall)

I am having this same issue with many things I enter into FireFox at the moment. What is wrong and how can FF resolve it?)

I have been using Firefox on Ubuntu for over 5 years over the past few months face book does not recognize me when I sign in. Face Book ask me to confirm it is me signing in as they think it is someone trying to hack my account. They send me a code to my email I put this into face book and they let me in to my account. They ask me to change my password this i tried they would not except it as they did not recognize my web site connection. They ask me to sign by another means IE mobile phone this I tried but Face Book did not except that either. I also got a notification from MY Heritage web site this is what they sent me.

We noticed that your My Heritage account was accessed just now from a new device or location: Firefox on Ubuntu | United Kingdom If it was you and you recently logged in from a new device or a new location, all is well and you can ignore this notification. Note that this notification may have been sent to you due to changes in your internet connection (e.g. a new IP address was assigned to you by your provider, or a recent use of a VPN service). Can anybody help please Thank you in advance Tony

I believe AT&T has developed a "POISON PILL" TO KILL ACCESSING AT&T PERSONAL ACCOUNTS USING FIREFOX. I originally had issues accessing AT&T Email on Yahoo \ Currently (take your pick) via Firefox and Edge and found a workaround with Google. Today(5-9-25) I could no longer access my personal wireless and internet account using Firefox. A CHAT live Agent told me ATT.COM no longer works, and ATT.net no longer works, only Currently.com is used. A quick switch to Google put the LIE to that. Currently.com is only for Email service. ATT.com and ATT.net both work but not with Firefox. This is probably an AT&T collusion with GOOGLE to create additional problems for Mozilla\Firefox. All it takes is one MINION on both ends to crash the system.

OR, it could be as simple as a few security setting flags in Firefox being set to a configuration which new security protocols cannot understand.

If I could figure it out, I could probably work for cloudstrike or Google and make tons of money.

I have been told that interact with my internet email service provider does not allow me to do such things as add attachment to emails because my firefox browser is using an improper buffer size. The email service provider tech would not speculate on what that buffer size should be. Only to state that Firefox had it wrong and a Firefox tech could explain the problem to me further..

 I am also finding that when I try to use firefox  address book I get this response...

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

Can someone enlighten me on these issues.?
