Have you tried zooming /questions/847465 or scrolling.

If you continue to have problems more information would help. Please answer in the current (or your own) thread:

• What display resolution are you using ?
• Exactly what is lost, and sides or top ?
• What does it affect, does it occur with blank pages, or only certain websites
• Maybe you could add a screenshot from
  • firefox 4
  • and firefox 5 so everyone can see what is happening.
• (asked originally in thread /questions/847840 )

go to help at the top of your firefox browser an click on help then click on restart with Add-ons disabled, Firefox will restart as basic and it should be back to normal, then you can turn the add-ons back on by going to tools at tghe top of the screen and then click add-ons

this worked for my problem

Some users are finding it is the Babylon toolbar causing this, anyone wish to confirm this, or say something else causes the problem ?

John99 true my default page is the babylon tool bar...

Thanks for confirming that, presumably disabling the Babylon toolbar by using Firefox Button -> Help _> restart with Add-Ons disabled solves the problem.

Or better still disable only the Babylon Toolbar

• Firefox Button -> Add-Ons -> (select relevant extension & disable/remove) (or pluggin)
