hello Stuhak
i suggest you download Portable Firefox or Google Chrome
Link for Portable Firefox - http://portableapps.com/apps/internet/firefox_portable Link to Google Chrome -
http://www.google.com/chrome/
Both Portable Firefox and Google Chrome do not need administrator access to install and run. Also, these programs have their own settings and are not immediately filtered/blocked by common web filtering software.
Im initially guessing there might be some security or web filtering restrictions imposed by your IT Department on the laptop. Please try installing and using Portable Firefox and Google Chrome. Let us know what happens. May your internets be free and accessible
regards
