Hello, I'm new here been using Firefox for a number of years. I have a computer with Windows 7 using Firefox Quantum 63.0.3 (64-bit). I use free home version of Avast. This happens only at ebay.com when I click on the 'login' it sometimes comes up with the message 'Threat secured We safely aborted connection to www.ebay.com because it was infected. However I am still connected and at the sign-in page where i can indeed signin and use ebay normally. I've tried everything including a complete restore of my computer. I tried another new computer and it gives same message on firefox with Avast. All other browsers including Google Chrome and Avast Secure Browser have no issues. Do you think this is a false positive with Firefox? I'm new here and enjoy Firefox . Ebay support said to stop using Firefox! I want to continue using Firefox so please someone with knowledge or experience with this please respond. I did a lot of research on this and it appears people who use Avast or AVG seem to have had the same problems with ebay over the years with this JS: redirect in one variation or another. Thanks! edit: removed space on last paragraph as it resulted in horizontal scrolling.
