Diễn đàn hỗ trợ Firefox

I have been unable to access any secure sites since I installed Norton 360 Antivirus. Whenever I try to access a secure site I receive the reply: Secure Connection Failed Error: PR_END_OF_FILE_ERROR I have tried all of the repairs listed on the internet but none have corrected the fault. I have also tried disabling Norton but also without success I have also tried uninstalling and re-installing Firefox but without success Can you suggest any other methods to correct this fault

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

Firefox only works properly if my VPN location is in Canada, but I'm in the US. If I switch my VPN to a US location (where I live), Firefox often does not work properly. I get news, ads, etc., that assume I'm Canadian. And often a website will not open. I need my VPN location in the US to access any site I normally do.

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 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.

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".

My anitvirus software is blocking a website that I use. Its legitimate. How can I unblock it?

hello team, I currently locate in China. days ago i have tried a vpn called "Veee". since then i could not log in many websites. i have asked Veee team but they say they dont know. it really sucks. i also asked AI tool but none of the method works. i think the vpn has changed some settings of my Firfox. because i can actually log in those websites with Edge. but i only want to use firefox. the errors either "cant connect" or something like refusing my access. please help. i love you guys.

Malwarebytes is picking up and blocking an outbound connection request from Firefox - www.highperformance.com. Anyone else experiencing this?

WHY DO I KEEP GETTING THIS ERROR???

"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."

I never got this before but now i get this every week. restarting my computer does not fix the problem. this sucks! the article to fix this are way too complicated. how do I fix this? I use Ccleaner and reboot, but that does nit fix the issue either. HELP!
