For example on Ebay clicking on a product has no effect unless you refresh the page. For every click it needs a refresh. I have it on different computers and it's the same for all of them.
On Firefox 56 developer edition it works OK (just like on 54), so it's a matter to wait V56 in the Firefox release channel.

pourquoi rien n'ai fait sur le problème des ouvertures de certaine page ,simplement message comme quoi (un script est occupé ou ne répond pas)ou une autre page en ouverture caché et qui bloque le navigateur

Awesome for this possum my Dawgs

No more adds, aaah!!! Thank you!!!!!

Zuverlässig, sehr umfangreich und verdammt schnell. Perfekt!

Not working with ebay, url changes but content not.
If disable ublock origins in extension, all works prefectly

It's an awesome extension for blocking ads and you can put list import and export the list for blocking ads on the site that user might not want to see ads on. 4 stars for the fact they support Firefox57+ ^_^

Nhẹ, nhanh, mượt.

It works fine.
