    I am also using Firefox 61 but I am not getting an error messages on the site.

    I just updated Firefox on W8.1 and at first it didn't work and then after clicking retry once or twice it loaded. The original post was from my Windows 7 machine and it still isn't working properly.

    Did the same on my Windows 7 Laptop (old Sony Vaio) and it didn't load it but I clicked retry and it worked. Went back to the original offender and it took many attempts to get it to retry but it finally played nice and I reloaded Firefox 61 and it still worked. Very weird, only this site wouldn't load. Working OK now.

    Hmm, upgraded to 61 just now on W10 Spring Update, but no issues.

    Did it again this morning on my Main Desktop, but when I clicked retry it sat there for a while then got into the site.

    Happened on my old Win7 machine in the back which is the 4th different machine with this error. 3 of 4 are Windows 7, 1 is W8.1....

    Any thoughts on what this issue is?

    After testing that the site works just fine with Firefox 61 on both Windows 7 and Windows 8.1, I did a search online and found this reddit thread:

    It appears to be a problem with TLS 1.3 and AV vendors with their HTTPS scanning feature turned on being unable to handle TLS 1.3, as Firefox now uses TLS 1.3 where available, including on and this site (it looks like Cloudflare has it turned on by default, which I believe this site uses).

      And I use the built-in Windows Defender and home and Kaspersky End Point Protection at work... I haven't had problems with either, all on Windows 10 though.

      The two sites you mentioned were/are the only two sites I have had problems with. I didn't have issues this morning getting on here. I saw that TLS 1.3 in the release notes and wondered about it. Well now I know. Thanks for the headsup.

    No errors with FF61 on (or any other website) here. I wish you success in solving your problem.

    Mozilla doesn’t break out the precise numbers for Firefox, even though the agency does say “half a billion humans around the arena” use the browser. In other phrases, it’s a chief platform that net builders should keep in mind. Biker Leather Jacket

    It solved itself, about 3 days after I got those messages it stopped doing it on all of my machines. I didn't change anything, teething pains?
