The best way to study Finnish would be to have Firefox portable and to pull the web page you want to bookmark to your Firefox bar. See here.In case you don't have a Finnish keyboard and you would like to spell check your writing, you could first use the virtual keyboard and the cut and paste the text in to this window and let firefox do the spell checking for you. You would need to have the right language packs installed to Firefox. If you are working across different computers and often away from home have firefox portable installed on a USB2 flash stick. I recomend 1GB
