Menu disappears in firefox

Hello,
When I go to the security check pro dashboard, and go to click on the menu items on the left, those menu items disappear after being hovered on. Please let me know what I can do so this can be improved.
Security check pro: 3.1.3.
Joomla: 3.9.1
PHP: 7.2.13
I use the Firefox browser 64.0 (64-bit). I did try Chrome and didn't have any issues.
Thanks,
Sarah

Hi Sarah,

Firefox is my browser of reference when I designed and tested the extension, so believe me when I say that if there is a browser tested with my extension is firefox.

Maybe there is another javascript causing conflicts with mine; do you use any browser's cache? If so, try cleaning it. Also, can you use the firefox feature "Inspector" and send me an screenshot of first lines into the "Console" tab?

If you don't know how to do that or you don't have time, just send me administrative credentials to access backend and I will do the tests.

Jose

I am having the same problem. I was using Chrome, but on reading this post I tried Firefox, with the same result. I have cleared the cache but that makes no difference.
Attached is a screenshot of the WebDeveloperTools Console tab, does that help?
Thank you.

Hi margknox,

Please, read this forum entry and tell me if it works.

I do't have the skyline scrolling plugin, nor any that seem to me to be similar.

Could I get access to the site? If so please send me administrative credentials to the email from which you receive forum notifications.
