Is this with many websites, some, a few?

Start Firefox in Safe Mode {web link}

A small dialog should appear. Click Start In Safe Mode (not Refresh). Is the problem still there?

few. I tried safemode also. Problem didn't disappear. But there was also no main menu

I loaded

thanks for your answer

I see this happening as well. The page is designed to resize the images to let them take up available screen space.

You can also see this in "Tools -> Page Info -> Media".

Ok. But 2nd problem context menu (right mouse click) is missing using my firefox only when I load the page from internet. When I load a private copy I get a context menu.

A website can disable the context menu and possibly replace it with its own context menu..

You can set this pref to false on the about:config page to prevent this,

• dom.event.contextmenu.enabled = false

thanks
