Hello Since about 3 years can be more, some websites make Firefox completely freezer !!!! Especially the site cdiscount france ! Whenever i go to their site, i look at one or two items, and firefox hangs completely, it freeze !!!! nothing answers the mouse, everything is blocked and i am obliged to close firefox with the firefox icon at the bottom of my screen !!! then restart it for firefox to work again. I'm pretty sure it's the firefox ublock origin extension that causes me this problem.Except with the google chrome browser or i also have ublock origin and the same ublock filters enabled, the site cdiscount is never freezer google chrome !!!! several other websites make freezer also completely firefox I specify that i have already tried to erase the cache and cookies firefox thousands of times and it does not solve the problem, the problem is that firefox reacts, manages very bad ublok origin !!! So there is a firefox problem that is poorly programmed, do not tolerate ublock origin !!! Please fix this big problem finally, mrs the developers of firefox please thank you
