The firebug font is way too small to read and I cannot find the means to
increase it (the increase text size in the drop evidental refers to the text
size of the subject tab, not the firebug interface.  Nothing at all seems to
be in the Net tab, however, it is not clear this is active when the subject
page is loaded.  Firebug crashes firefox repeatedly when the subject page is
reloaded or when firebug offers to reload the page itself.

The first page after login (twitter "Home") always stops in the same place
-- after it draws the tweet box in the left column (but leaves the tweet box
non-functional). Some of drop-downs on the top bar work, but others do not
drop down.  Links in tweets do not open in new tabs (as they usually do) and
if they link to twitter pics, those pages will not fully load.  Using the
reload link in the "slow loading" message will (at first) reload pages which
generally stop in the same place, but repeated reloading eventually leads to
nothing but the background showing up.

My understanding from reading the xwin list and others is that the intel
driver is in some aspects broken for x.
