I continually get error messages for webpages. I turn off my VPN, clear my history. Not sure what else I need to do. Last one was the webpage for Lindt Chocolate. Come on. Why am I getting error messages for this? I have been on this page before. There are other places also, like Macys. Getting fed up with Firefox.

Ich habe die Firefox-Einstellungen von einem alten Windows10 Rechner auf den neuen Windows11 PC mit den Profildateien übertragen, hat gut geklappt.. Jetzt hatte ich die Meldung erhalten " der Treiber cpuz419_x64.sys konnte nicht installiert werden wegen möglicher Virus-Gefährdung", als Abhilfe wurde angeboten die Ker-Sicherung auszuschlaten. Das habe ich mir nicht getraut. Als weitere Info erschien eine Seite, auf der "Windows10" unterstrichen war. Könnte das alte Profil dem Rechner vorgaukeln, dass ich Windows 10 nutze?bold text

I installed update 149 and since then, the VPN (NORDVPN) often will not start up and I have to restart the computer. If this cannot be fixed, I would like to go back to the previous version which gave me no trouble. thanks Brian

I was in contact with Bitdefender Support and they suggested the following:

If Facebook still won't open, open Bitdefender and:
  - Go to Protection > Online Threat Prevention > Settings.
  - Turn OFF "Encrypted Web Scan" temporarily.
  - Now reload Facebook in Firefox.

Afterwards, I also had to click on "Messenger" to get all my contacts.

This is temporary since before FF 150, Bitdefender ran with "Encrypted Web Scan", and I had no problem in loading Facebook. So something that changed in FF 150 conflicts with Bitdefender's "Encrypted Web Scan".

I AM JUST TRYING TO MAKE SURE THAT MY MOZILLA FIREFOX ANDROID BROWSER SETTINGS MATCH MY VPN BUT SOMEHOW I CANT GET TO THE ABOUT:CONFIG PROBABLY BECAUSE I AM USING AN ANDROID BUT THERES GOT TO BE A WAY T OK MAKE SURE MY VPN AND MOZILLA ARE ON THE SAME PAGE. I HAVE BEEN GOING IN CIRCLES ALL NIGHT SOMEBODY PLEASE HELP ME.

So, on my pixel I am using my VPN and am getting tired of having to do the Captcha thing everytime I put in a website, I am about ready to uninstall Firefox. I have it synced with my desktop and never have this problem on my PC. How do I stop this?

I've started getting Virus/Trogen warnings from McAfee popping up every few seconds on Firefox. There was a McAfee file on my Acer desktop but Not installed. Windows Defender and Malwarebytes do not detect a Virus or Trogen. Is this a SCAM by McAfee to get money from me? I cannot delete the McAfee install file as it says it is in use!

I would like to know what are the best Antivirus Protection to use with Firefox. Previous information is from 2011 and I would like to get more current information. Thank you

The bookmarks and history system will not be functional because one of Firefox's files is in use by another application. Some security software can cause this problem.

When I try and connect to a site with firefox I get a message saying "Check that Firefox hass permission to access the web (you might be connected but behind a firewall) How can I get check to see if I am behind the firewall and if so how can I get out to connect to that specific site.

While In the British Virgin Island would it be possible to stream Pandora or Spotify through the Mozilla VPN? Would the streaming platforms think I am in the US? I’ll be using my IPad Pro 13 or my Iphone 17. Would I simply open the Pandora app on my device or would I need to log into the pandora site through the Mozilla browser? Thank you, BF

when visiting websites using my vpn firefox blocks my entry. I have to disconnect my vpn to allow entry to sites. ive tries numerous fixes and nothing works its frustrating.
