In Firefox, the "style" g_request_var is not assigned correctly, it is always returned NULL.
This makes it impossible to switch to List or Grouped view, though this works correctly in IE.
in the changeBlockStyle() function in misc.inc.php, the get($key) function simply does not get the value of this variable from the URL.
I solved the problem by changing the key 'style' to 'list_style' in the following places:
misc.inc.php - 138
list_tasks.inc.php line 243 to 271 changed.
list_files.inc.php lines 140-160 changed.
list_projectchanges.inc.php - lines 88-102
list_projects.inc.php - lines 200-212
list_versions.inc.php - lines 85-97
It seems that Firefox has a reserved purpose for this word, or something else is preventing it from returning correctly.
I have not yet seen any side effects from performing this modification, other than in the Documentation tab, which does not work correctly with these views on either browser.
