Hello,

This is likely not a Firefox issue.

In order to see if it is, please try accessing the same website on another browser. If you get the same result, the problem is likely with your IP address or computer.

I accessed the website using Safari. I got on. But I couldn't get on using Firefox.

Tried again. Now I was able to access the site on Firefox.

I suspect this is a Firefox issue, because I encounter it too (primarily for rei.com as well), and only when I'm using Firefox. If I clear all cookies for REI I can navigate to it, but as soon as I click a link and get taken to a 2nd REI page, it gets blocked again (presumably because on the 1st page REI sets a cookie, and on the 2nd page REI recognizes the cookie and decides to block the browser). Blocking all cookies from REI is actually an okay workaround, except for the fact that it means I can't log into my REI account, which is a big issue for doing any actual online shopping.

I'm guessing this is some sort of overzealous bot-blocking attempt on REI's sysadmin's end, but if we can figure out WHAT specifically they're running into with Firefox, it would be easier to maybe get them to fix it, if we can't fix it from our end.
