Hangs upon opening. It’s not even possible to close the browser without the task manager.
I tried it in safe mode, in a clean profile, on another PC and another network - the same result.

Good for Firefox. How does that help any of us?

From what little I can gather it's a recursion problem in the website (potentially linked to timeouts/intervals) that triggers when the page has loaded. I'm not sure what it's trying to achieve but it floods the event loop with calls. There's very little that can be done to counter this kind of scripting lockup.

It seems to specifically hang up on this script:

Code: Select all

https://get.optad360.io/sf/17f2705c-51de-11e8-86dc-06048607e8f8/plugin.min.js
The site loaded/scrolled fine for me when that was blocked.

And fwiw, it also seems to load ok, with/without that script, when cookies are blocked.

Thanks for pinpointing the culprit; I've contacted optad360 about this. This may be a problem on all sites that have their WP plugin.

(and updated the lunar blocklist for ABL to include them as blocked domain ;-) )

Right, the page is loading fine with adblockers and without it hangs.
