duplicate of /questions/1574919 thread

I am getting a lot of pop-up messages for existing of many viruses on my computer. Please help me protect and then permanently remove these viruses from my computer.

Hello everyone,

I am using Firefox latest release (eg 145.0.1).

At https://developers.cloudflare.com/ssl/post-quantum-cryptography/pqc-support/ , it seems that X25519MLKEM768 is supported since Firefox 132. Do you confirm ?

I ask this question because when I am connecting to https://pq.cloudflareresearch.com/ and activate the network tab before reaching this URL, and looked at the security tab on the right bottom panel, as you can see in the screenshot attached, in the Exchange group keys, I see x25519 and not x25519mlkem768 meaning that Firefox is not PQC ready for key establishment :-(

Best Regards.

I have been using Firefox for many years and never had issues. Two days ago, I turned on my HP with Windows 10 and I got a pop up message something about Error Platform 126.0 XUL Runner is not compatible. I could not access Firefox, Google, or the internet. I uninstalled Firefox and reinstalled, but after that, everything runs very slow. Each time I go into a website, it can take up to over a minute to pull up! I cannot even delete email from my Gmail! It's piling up. Downloading can take over an hour! I checked all the trouble shooting forums in Mozilla and tried just about everything. I went back into "About:profile"s and created a new profile. It it did not make any difference. I also did a Firefox refresh. Did not help any. I went back into the profile I had before the XUL error because my bookmarks were there. Still slow. I cleaned out the cache, in both Firefox and my Windows 10. made no difference. I only have three extensions in Firefox. I don't know what else I can do to fix this. Also, my drivers and other software are automatically updated by Windows. My HP is only 2 years old as well. Everything was fine in Firefox until that XUL error message popped up and I had to uninstall and reinstall Firefox. That is when everything became agonizingly slow!

Update: My computer is barely usable anymore because of the Firefox issue. Having to wait for a minute or more for everything I do on the internet? I know it cannot be my computer itself because it is not even two years old yet. I may have to dump Firefox if I cannot get this fixed. I have Norton 360 and it is not malware or a virus. Firefox messed something up.

I uninstalled Firefox on my computer and reinstalled it, but when I logged in, the account couldn’t sync, it was as if the sync couldn’t retrieve any data from the server. Nothing happened at all.

On my Android phone, the data is still there, but when I tap “Synchronize now,” nothing happens either. I’ve tried signing out and signing back in multiple times, but still nothing works.

I also tried switching to a different computer and a different internet connection, but it still didn’t work.

What should I do now?

I reinstalled the operating system, so to speak, changed my device. I clicked the sync button and it worked. I reinstalled the operating system and reinstalled the browser. I logged in, nothing happened. I rebooted, nothing changed. I clicked sync, everything was the same. Where are my bookmarks and passwords?

I have both Win7 and Win10 on separate drives. I have been migrating from 7 to 10. From all appearances Firefox on both OS's are sync'd. I have asked for my passwords to be sync'd, yet they have not migrated to Win 10. Bookmarks have so I know something is working. Any advice? Thanks Chris
