Dear Kwiq,
It is normal that you can't access to URLs showed on my movie : they only work on my computer.
What you are asking to me is how to create a website in local environment, using WAMP. It's pretty hard for me to teach you that.
Even if i do so, the issue is noticed in very specific conditions :
1. I create the website with the framework Wordpress
2. I'm using a javascript library called barba.js. Its purpose is to allow to create smooth website page transitions without having to refresh the page.
example of barba.js smooth transition :
https://barba.js.org/v1/demo/nextprev/2.html Barba.js is using ajax (
https://en.wikipedia.org/wiki/Ajax_(programming)).
3. The issue happens when Barba try to load the new page.
But i have some news.
Since i disabled the 2 suspicious shields, i noticed some miraculous improvements :
1. to load pages in Firefox is so much faster.
2. I'm playing a french MMO game, made in flash. (

For months i couldn't play it anymore due to hard freezing. Now it's perfectly smooth.
I wonder if it's not easier/funnier for you to reproduce my issue by testing this game, rather than some WAMP testing ?
The game is English friendly, and you can test it without having to pay a subscription.
This weekend i will take some time to record a video of the game, showing you differences with/without the both shields.
After discovering the solution, i posted on the game forum to explain other players how to remove both shields. Some grateful answers show that i'm definitively the only one to have theses issues!
So... WAMP or Dofus ?
regards
