i'm having this really serious problem with wanadoo/orange broadband. my internet connection always messes up and keeps going on and off which is really taking the piss up to the point i really feel like GETTING the whole *censored* pc and the modem and bash it outside the window coz getting access to one site takes like 10 mins T___T

i'm using firefox but today, when my internet connection messes up, i've decided to safely remove the hardware and unplug the internet modem but as soon as i do that, the PC automatically restarts and i ended up losing my essay which i can't recover. then, i OPEN firefox and REALISED that there's no tab on the up screen. people who use firefox might understand what im trying to say, i mean those tabs where u can go on separate websites in one window. how to REGAIN that?
and lastly(i hope, i havent check anything yet),all of my precious bookmarks are deleted which really make me frustrated coz i got some important sites there.
can anybody help me?
