This page describes the various preferences available for
controlling the behavior of Dust-Me Selectors, as well as aspects
of its interface. It has quite a lot of options, which are
described below…

Main status

Disable Dust-Me Selectors

If this option is checked then Dust-Me Selectors is disabled.

Default: Not-checked

Show icon in status bar

If this option is checked then the main Dust-Me Selectors icon
will show in the status bar, and therefore the extension’s functionality will be available
from there as well as from the Tools menu. If not checked then
the status icon is not shown and the functionality is only available
from the Tools menu

Default: Checked

View

Remember dialog sizes

If this option is checked then the View selectors and Spider
dialog will remember their size and position between views.

Default: Checked

View selectors after manual run

If this option is checked then the View selectors dialog will
automatically open after a manual Find operation
(triggered by clicking the status icon, or selecting Find redundent selectors
from the menu).

Default: Checked

View selectors after automatic run

If this option is checked then the View selectors dialog
will automatically open after a Find operation that’s triggered automatically
in response to a page loading.

Default: Not-checked

View selectors after spidering

If this option is checked then the View selectors dialog
will automatically open after spidering a site.

Default: Checked

Automation

Run automatically

If this option is checked then a Find operation will start automatically
every time a page loads.

Default: Not-checked

Run again if the DOM changes

In combination with the previous option, if this is checked then
a Find operation will re-start if the
DOM of the page that’s being
checked changes during the operation, for example if scripting
causes it to change.

Care should be taken with this option — if a page is so dynamic
that it changes continually, then a Find operation on that page may
never complete.

Default: Checked

Spidering

Don’t spider external websites

This option affects the behavior of the spider.
If checked, then it will restrict itself to checking pages
that are on the same domain as the sitemap itself.

Default: Checked

Don’t spider "external" or "nofollow" links

This option affects the behavior of the spider when using an
HTML sitemap.
If checked, then links in the sitemap which have
rel="external" or rel="nofollow"
will be ignored.

Default: Checked

Restart pages if the DOM changes

If this is checked then a Find operation on an individual page that’s
part of a spider operation will re-start if the
DOM of the page
that’s being checked changes during the operation, for example if
scripting causes it to change.

Care should be taken with this option — if a page is so dynamic
that it changes continually, then a Find operation on that page may
never complete.

Default: Checked

Stylesheet rules

Ignore query-strings in stylesheet URIs

If this option is checked then query-strings in stylesheet addresses
will be ignored. This means that, for example, main.css?v=1.0
will be treated as though it were just main.css

Stylesheets inside IE
conditional comments are loaded externally,
so if this option is checked and the path contained a query string, it will
be requested without the query string; if the stylesheet is dynamic and relies
on query information then its content may not be as expected.

Default: Not-checked

Test simple element selectors

If this option is checked then the extension will test for redundency of simple
element selectors like P or UL. If not checked then
all such selectors will be assumed to be used.

This control does not include descendent element selectors like
DIV P — such selectors are always checked irrespective of this setting.

Default: Checked

Account for common CSS hacks

If this option is checked then the extension will parse common
CSS hacks to
re-create their underlying selection; for example,
* html .foo will be tested as though it were just
html .foo.

The following CSS
hacks are parsed:

• * html will become html
• *+html will become html
• *:first-child+html will become html

Default: Checked

Saving data

Save data for each site separately

If this option is checked then selectors for each site will be saved
separately. If not checked then all data is saved in a single global list.

Default: Checked

Ignore port number differences

In combination with the option above, if this is checked then, for example,
site.com:8000 and site.com will be treated as the same
site for saving purposes. If not checked then they will be treated as
different sites.

Default: Not-checked

Ask before clearing saved data for a site

If this is checked then a confirmation dialog will be shown before
deleting the saved data for a single site; if not checked then no
confirmation will be asked for.

When deleting data for all sites at once, confirmation is always requested.

Default: Checked

Save data in my preferences folder

If this is checked then the extension will create a folder called
dustmeselectors-data inside your profile directory, and save
data in the form of
JSON
files in that directory. If not checked then
you can select a folder for these data files to be kept in.

Either way, the data files only have write permissions for the user that
created them, so you cannot select a folder or profile directory
belonging to a different user account on your computer.

Default: Checked

Use the following folder:

In combination with the option above, use this to select a folder
in which data will be saved.

Default value: [no value]
