Broken image on Prestahop blog module, Happens on Firefox 56

[searaoracle]

Hi, anyone can help?
I'm trying to install a blog module to my client Prestashop website.
Everything works perfectly on all web browser except firefox ver 56.0.1, Images are broken into lines and very blur plus Javascript seems not to be working
I spent many hours but can't figure out the problem, why it only happens on Firefox 56.0.1? why it's not happening on old versions or other web browsers include other Firefox ver 56.0.1
This is the module I installed: https://www.prestashop.com/forums/topic ... og-module/
I also tried to contact the developer but he was also not able to figure out the problem

Hope anyone can help and save my project

Thanks

Have you tried starting Firefox in Mozilla Safe Mode? http://kb.mozillazine.org/Safe_mode
If no improvement using Safe Mode, do you have the same problem if you create a new profile and test it with no extensions or non-default themes installed?

Can you give us a screenshot to show what you mean?

I tried on private windows, it still happens, so it's a problem of cache or something
it's css issue on the firefox version because it doesn't happens on other web browser.
I'm searching css tricks to fix the issue

In a Private Browsing mode the disk cache isn't used and a separate cookie jar is used, so if it still happens in PB mode.

Can you show us a screenshot to see how you see the page?
Maybe that gives us a clue of what is happening.

Also make sure you aren't zooming the page (View -> Zoom -> Reset).

Third party cookies & some of the other "privacy" stuff (when blocked) has been known to do odd stuff on various sites.

As a test, I'd create a new, clean Profile, load the page & ... what do you get?
