Not so big really. Not as bloated as the new MS Office (although it doesn’t do the forms you fill out on the spot like the newer MS Office does, which means college students might require MS Office these days)
Last thing I want is bloat. Wasn’t till earlier today I found out about the little Firefox PDF glitch, because last night I was trying to open a ten meg PDF.
Firefox has built into the later versions a (non-functioning) PDF previewer.
Turn that sucker off and FF runs faster. All the time, not just when you are trying to view a PDF.
