Javascript from anrdoezrs.net.
Fire one for effect.

FYI, this is not a change on my end. I have always had js from anrdoezrs.net blocked. It appears to be a commission junction spook.

@dangeruss Well, we’ve solved the problem, but haven’t yet narrowed it down to exactly what I have to work around. All I did was disable AdBlockPlus andNoScript. I will narrow it down and report back on which piece of $*#(% is the culprit.

Thanks again, and sorry for adding to everyone’s workload.

Edit 1.
ABP enabled and all okay. This isn’t encouraging.

@griz , @zapjb - Thanks for the suggestions, and I will look into each after resolving the current problem.
@SlimTim - Thanks, and I may be forced to upgrade FF.
@FrugalFreak - Thanks for the confirmation of FF56 with a similar config working.
@dangeRuss - Cache cleared per an earlier suggestion from FrugalFreak, I believe, but will try again. All cookies also deleted on browser shutdown. I’ve also removed the fake identity and the browser now identifies itself properly. Thanks for your other suggestions, and I will try them. I’ll only add to your workload if I can’t decipher them. This is obviously something in my configuration which has changed (despite my always perfect memory saying otherwise).
Thanks again to everyone for all the responses.

Box fans are great, but keep in mind they suck watts big-time.

Disabled AdBlockPlus and closed Firefox. It makes no difference. Sorry to be a PITA. Of course, I’ll say what everyone says - nothing changed on my end. “smiley”

@zapjb - My cookies are delted everytime I close Firefox

@dangeRuss - I’m using Firefox 43.01, possbily disguised as 45. I have enabled Javascript for phatwalletforums.com and the amazon aws server that occasionally asks to run Javascript. However it is disabled for ebay and anrdoezrs. I also use AdBlockPlus and initially tried to disable it to help support the site, at least until I found the requirement for Javascript. I will try temporarily disabling ABP and report back.
