Firefox on Ubuntu seems to render some HTML considerably differently compared to other browsers. In particular some fonts/styles on Ubuntu are becoming much larger and columns of text which rely on equal numbers of line breaks to keep them aligned are no longer aligned on Ubuntu Firefox.
I have have been given some HTML which was made in iWeb and it displays correctly on all major browsers except for Firefox on Ubuntu. (Firefox on Windows works fine)
I am running Firefox 3.0.12 on Ubuntu and I have the Ubuntu Firefox Modifications add-on turned off.
What could be causing this problematic discrepancy with Firefox on Ubuntu?
Update: I've discovered that a copy of the HTML stored locally on my own machine actually renders the columns correctly aligned but when viewed online it becomes unaligned.
I've tried installing the Microsoft fonts package but that hasn't helped.
Update 2: With the columns issue, there seems to be at least two problems. One is that iWeb broke one of the columns into two blocks of code and placed it around the code for the other column. Once I made sure each column was created by a contiguous block of code and removed some now redundant divs, the alignment was a lot better on Ubuntu but not perfect. These changes didn't seem to affect the rendering on other browsers either.
Digging around with Firebug, it seems that I can fix the problem on Ubuntu completely by removing the font-size attributes for all relevant text. However this then breaks the alignment on all the other browsers - now I'm back to square one again.
(And yeah, I know that the way the HTML is designed is kinda bad practice, but I've just been given the code so I don't really have much choice)
