Have you installed anything of late? What link did you use to send your donation?

Do you have Malwarebytes Anti-Exploit installed? And can you tell us what exact errors you're seeing or screenshot them & attach them here?

Malwarebytes Anti-Exploit is giving some people a "Couldn't load XPCOM" error.

It would be a very hot topic here if Mozilla was doing any form of attacks on your Firefox install after a donation

You really need to give more details on what and where that Malwarebytes is claiming on.

Thank you for your replies. I did not mean to infer that Mozilla caused the problem. I used PayPal for the donation.

I have not installed any new software. I logged off my PC (disconnected from the internet) after I made the donation. When I logged back on about 3 hours later, and tried to initiate Firefox, I started to get repeated notices from Malware bytes about a virus intrusion. It was going after the Mozilla 86 files. It said it was something like "ss.syscd.com". I started Malware bytes Chameleon (mostly by accident), and I ran a scan. The scan killed the virus.

I don't have Malwarebytes Anti-Exploit installed.

Posts about Malwarebytes and *syscd.com have been popping up for a few days and none of the other threads had any mention of doing a donation.
