What does the new message "Ignore files modified in the last xxx Hours" mean?
This is due to a new option for the Temp Folders configuration
sub-tab. You can turn the option on /off and can specify the number
of Hours to be considered for the age.

messages from the Temp Folders option by skipping the purge of newer files
in the Temp Folders.
The default setting is "on" and "8" Hours. You can
access these settings by clicking the Configuration tab and then
Clicking the Temp Folders sub-tab.

Consideration was given to supporting
FireFox cleanup within PurgeIE Pro.
Consideration was given to
creating a Plugin for FireFox. This proved problematic
as each installation of FireFox uses a unique name for its
subfolder names. This would require such a Plugin to be
manually tailored by each user.
Further, a Plugin
would not provide a means for retaining good Cookies. The storage for
Cache and Cookies was entirely different for FireFox from that used by

button does not allow you to keep the good Cookies. PurgeFox provides a convenient
means for you to protect your good Cookies so that its
Purge Cookies function will not delete them.
- PurgeFox has an option to place a
special [PurgeFox Now] shortcut on the desktop for a one-click
cleanup. This will execute the cleanup based on the options you have
- FireFox's [ Clear All ]
button clears all of FireFox's History, Forms History and Cache as
well as clearing all Cookies. If you only wanted to clear
some of these, you would have to manually clear them

Profile to locate the FireFox Folder used for storing Cache, History,
etc.. The current User Profile is the last one used when starting Firefox

Can I execute PurgeFox if FireFox is open?
You should close FireFox
before executing PurgeFox. As both programs work with FireFox
data files, the following PurgeFox Options would not function properly:
FireFox History File
Firefox Forms History
Beginning with version 2.03, these functions are
not processed if a FireFox
window is open. Attempting to Purge with these options if a FireFox
window is open will produce an error message. A conflict was
discovered with webpages which used CSS (cascading style sheets) when the
FireFox Cache was not completely cleared.
Also, the PurgeFox Cookie
window may not show the same Cookies as FireFox when both are
open at the same time.
