Just a query - has anyone else had their browser jump back a page without clicking or anything? I have had it happen at home and at work, almost daily. It is just a little annoying...
Nope. What version of firefox are you using on both?
Do you happen to have the same addons on both, if so it could be an addon causing it, try running firefox in firefox safe mode which disables all addons, to see if that works.
My mouse wheel when pushed/clicked accidentally was programmed to 'back page' doing that on me for a while, till i figured it out.
