Question

I want to know the use of these options in "Web Developer Toolbar"

Disable > Disable Javascript > Strict Warnings

Disable > Meta Redirects

Disable > Meta Referers

Disable > Disable minimum Font size

CSS > Use border box model

Information > Display Table Information

Information > Display Table Depth

Miscellaneous > Show Comments

Miscellaneous > Show Hidden Elements

Miscellaneous > Show Window Chrome

Miscellaneous > Linearize Page

Answer 1

Disable > Disable Javascript > Strict Warnings turns off strict warnings that relate to minor 'bad practices' in JavaScript code. They are safe to be ignored, as they are quite picky.

Disable > Meta Redirects stops a page with a refresh header in a meta tag from being enacted, which would otherwise cause the page to reload or redirect.

Disable > Meta Referers stops the page from having access to the referring page's URI.

Disable > Disable minimum Font size allows font sizes to be as small as the developer wants.

CSS > Use border box model uses the box model used before IE6. When enabled, border and padding values are counted inside the width value. If not enabled, the default, correct behaviour will be used, where borders and paddings are counted outside of the width.

Information > Display Table Information (unsure)

Information > Display Table Depth (unsure)

Miscellaneous > Show Comments will turn HTML comments into visible elements.

Miscellaneous > Show Hidden Elements will unhide elements with visibility:hidden;

Miscellaneous > Show Window Chrome (unsure)

Miscellaneous > Linearize Page will make all elements display:inline;

Answer 2

For "Disable > Disable Javascript > Strict Warnings":-
The JavaScript Strict Warnings will not work from now on.

For "Disable > Meta Redirects":-
The HTML Meta Redirects will not work from now on, which would otherwise cause the page to reload or redirect.

For "Disable > Meta Referers":-
The HTML Meta Referers will not work from now on, which would otherwise provide access to the referring page's URI.

For "Disable > Disable minimum Font size":-
It disables the font sizes to be as small as the developer wants.

For "CSS > Use border box model":-
It uses the box model used before IE6. When enabled, border and padding values are counted inside the width value. If not enabled, the default & correct behavior will be used, where borders and paddings are counted outside of the width. This is correct as mentioned by "Delan".

For "Information > Display Table Information":-
It shows the HTML "Table" element's "Summary" attribute in a highlighted manner.

For "Information > Display Table Depth":-
It shows each HTML "Table" element's nesting depth. For example, if only 1 "table" element is used, then it highlights "Depth=1". If there is 1 more "table" element inside its parent "table" element, then it will highlight "Depth=2", and so on.

For "Miscellaneous > Show Comments":-
It will show all the HTML Comments, by highlighting a "!" character. So when the mouse is clicked upon that character, the comment gets shown.

For "Miscellaneous > Show Hidden Elements":-
It will unhide all the HTML elements, which have the CSS property "visibility:hidden".

For "Miscellaneous > Show Window Chrome":-
Unsure, but I think it will show the web page just like as it were in the Chrome browser.

For "Miscellaneous > Linearize Page":-
It will make all the HTML elements shown as "display:inline", as mentioned by "Delan".

Hope it helps.
