Web pages often freeze up to 30 seconds

Hi, I have problem with two web pages - www.idnes.cz and www.zive.cz . Some time is everything going well but at one moment the loading of page freeze and I muse wait for tens seconds. Unfortunately this tow pages are my favourites, visited several times per day :-) I am using primary MS Edge, but the same problem is with Chrome. I use Windows 10 Pro.

Thanks for solving, if possible :-)

Clicked on both links, and they load instantly here. Zero delay.

Tried in Edge and Firefox (v58) with latest uBlock, so not sure what the issue is.

@ondrejx I'll try to reproduce this. However if it's also happening in Chrome then that would indicate it's not specific to the Edge release, and therefore should be opened in the core repo.

@LordManhattan Hi. Yes, you are right - from the start is everything quick with zero delay. But for example, when when I start browsing of individual articles on www.idnes.cz, I open 6 articles without delay but next article freeze. Please try If you will have the same problem.

@ondrejx Confirmed!

I'm able to load the front page, but Edge basically crashes (freezes) if I try to open an article. Next step was to disable uBlock on that domain, and that actually solves the issue. Checked Firefox (58) w/ uBlock, and there are no issues.

Recap:

• With uBlock enabled: Only the front page loads
• With uBlock disabled: Everything loads

Details:

• Device: Microsoft Surface Laptop
• OS: Windows 10 Pro
• Edge version: 41.16299.248.0
• uBlock Origin version: v1.15.4
• Location: Norway

There's definitely an issue here but I'm having trouble diagnosing it. In the latest Insider build, the extension quits entirely when loading that website at all. I'll give it a go on the next build, and I also welcome diagnosis from anyone else who happens to have a chance.
