Mea culpa: I should have given ftang a testcase with justified text to check on Mac.

accept. I am not sure when will I work on this. 
I knew this problem and don't think need to fix that right away. I could be
wrong. how many top sites in Hebrew/Arabic use align=justify ?
Or any other reason I should fix this asap ?
Otherwise, I will keep this is one item "to-be-hack" :)

>how many top sites in Hebrew/Arabic use align=justify ?

Speaking of this- do we have an "offical" list of ME top sites?

In general, I am seeing this problem more and more lately- this is esp. bad 
whith pages genarated from word

just went back to mozilla.org.il (mozilla Hebrew l10n page), and found that the
evanglism letter there ( http://www.mozilla.org.il/evangel.shtml ) uses that
attribute, thus making it almost unreadble with my mozilla (build ID 2002061603
on Mac OSX)

Yet another site with the same problem:
http://www.blabla4u.com/sites/blabla4u/ShowMessage.asp?ID=992320
It seems like align=justify is the latest fashion- which makes reading the web
really hard.
any idea when this will be fixed?

I'm seeing this on Arabic pages using Windows XP as well. It seems that not all
fonts or font sizes are effected by this bug. I'm uploading a testcase and a
screenshot showing some distorted text using "Arabic Transparent." Mozilla's
default Arabic font on windows.

Mass-assigning the new rtl keyword to RTL-related (see bug 349193).
