I just discovered that by going first time on page everything is allright but when i click refresh....magic happened

see attachements

after ctrl+f5 magic happened

So I took a look at the first website that you listed.

The issue is caused by this stylesheet. There is a style property called .wf-loading body that contains visibility: hidden. This style property is hiding the content in your body.

I'm not sure why older versions of Firefox and other browsers are not detecting and applying this style element, but that is the cause of the issue.

Since this is a theme that was probably not developed by you, please contact the creator of the theme for further support on this issue.

I did take a look at your other website links that you listed and most of them appear to display correctly on my browser.

did You hit ctrl+F buttons on other pages ? After that pages disapear...

Pressing Ctrl + F did not have that effect on my end.

I revisited all of your websites again just now and they all appear to be functioning properly. I'm not sure whether you patched the issue or perhaps the theme developer fixed it, but either way, it looks like the problem is solved.

Is this the case on your end?

Yes I patched the issue via custom css.

thx

Glad to here it. Thanks for contacting Mozilla support.
