Diễn đàn hỗ trợ Firefox

I have a blank bookmark that cannot be deleted or moved. Have moved out other bookmarks in its folder, renamed the folder and tried to delete folder, but folder will not delete. All other folders can be moved up and down in the bookmarks list, but not this one.

Operating system

Windows XP

Youtube videos loads but after 2-4 sec the player area gets blank with ivory white colour..

This happened

Every time Firefox opened

I was looking at a page on the web, but now it has vanished. It should be in my cache, and according to about:cache it is. But a hex dump is not really helpful. Is there a tool that will let me look at the contents of the cache as web pages?

I am trying to upgrade from Firefox 3.0.3 to 3.6. I have downloaded as instructed but I am not allowed to complete the installation by moving the application into my Application Folder thereby replacing the older version.

It is my personal laptop and I know my install passwords but do not understand why it's giving me this message when trying to copy the new Firefox over the old Firefox application I currently have (vers. 3.0.3).

Any suggestions? I'm also concerned about all my organized bookmarks, would those totally be lost in the replacing of the software?
