Can you attach a screenshot?

• https://support.mozilla.org/kb/how-do-i-create-screenshot-my-problem

• Use a compressed image type like PNG or JPG to save the screenshot
• Make sure that you do not exceed the maximum size of 1 MB

You can reload web page(s) and bypass the cache to refresh possibly outdated or corrupted files.

• Hold down the Shift key and left-click the Reload button
• Press "Ctrl + F5" or press "Ctrl + Shift + R" (Windows,Linux)
• Press "Command + Shift + R" (Mac)

Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem.

• Switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance
• Do NOT click the Reset button on the Safe Mode start window

Please find screenshot attached. Thank you.

I'm seeing this logo in Firefox and in Google Chrome:

That is a different logo that what your screenshot shows, so I'm not sure about the difference in your case.

What code do you get when you check the logo in the Inspector (right-click: Inspect Element)?

Thank you for your reply. Once you scroll down the page the menu bar should change and the logo should change to this one http://rentfluff.com/wp-content/uploads/2015/07/fluff_tilted_logo.svg (screenshot attached) Please have a look in chrome or safari and you'll see what I mean. Thanks again, Isabel.

I'm not sure if Firefox supports content for images.
