For a limited bandwidth that can be a problem! It isn't so much as far as data but the ISP hosting being the problem for you. Are you on dial-up or some form of limited dsl plan? is the question I could be asking. 4gb is small since a Windows 10 download in iso form would be over 3gb in size! The unlimited on the other hand would allow you to download all day long!
Now as for having several browser windows open I find sometimes I may to use multiple browsers in order to and FB or Twitter page open as well as a few other sites and still be able to open any new windows required if something has to be looked up. This is one reason I had switched from IE 8 and later 9 years back to Opera and then found Waterfox which started acting up last summer when getting into 10. Cyberfox being an Australian variant was then tried and set for default while now I ended up with the latest 64bit flavor of FF!
That will also prevent seeing stalls or bog downs when having several windows open suggesting a max number for each browser over a period of time will help to prevent crashes from the freeze ups generally the most common. With 16gb of memory you know that can't be the reason! The browsers themselves have their own limitations you have to work with.
