When sending form data through post or get the tab character, ascii code 9, is only sent when enclosed between other characters.
In an html select with <option value="	">Tab</option> the value is left empty upon submitting.
The query string (using a get) should be: name=value but is in reality name=

Reproducible: Always

Steps to Reproduce:
1.Put source code, see: Additional Information, into html file
2.Open this file
3.Select an option and click submit
4.Check the query string, it has the form separator=value
Actual Results:  
tab   => (nothing)
(tab  => %28
tab)  => %29
(tab) => %28%09%29 (the correct value)

Expected Results:  
tab   => %09
(tab  => %28%09
tab)  => %09%29
(tab) => %28%09%29

Source code:

    <title>Tab char test</title>
    <form name="frm" action="" method="get">
      <select name="separator">
        <option value=",">Comma</option>
        <option value=";">Semicolon</option>
        <option value="|">Pipe</option>
        <option value=" ">Space</option>
        <option value="	">Tab</option>
        <option value="(	">(Tab</option>
        <option value="	)">Tab)</option>
        <option value="(	)">(Tab)</option>
      <input type="submit">

Version: unspecified → 2.0 Branch
This bug was reported on Firefox 2.x or older, which is no longer supported and will not be receiving any more updates. I strongly suggest that you update to Firefox 3.6.3 or later, update your plugins (flash, adobe, etc.), and retest in a new profile. If you still see the issue with the updated Firefox, please post here. Otherwise, please close as RESOLVED > WORKSFORME

In FF 3.6.3 sending a tab results in ++++ being sent, i.e. 4 spaces instead of a tab (%09), not exactly the same!

This bug is still present on FF 3.6.10 (OSX).

When inspecting the select-element with firebug the tab is missing from the attribute.

It seems to me as the tab-character is ignored when reading attribute-values of option-tags when it is in the beginning or the end.

The same thing happens with newlines.
Reporter, can you still reproduce using a current version?
If no, please set status to RESOLVED and resolution to WORKSFORME.
If yes, please provide updated information.

My current version of Firefox is 23.0.1
The tab character is now sent in the URL (GET) as %09 as it should be.
I consider the problem therefore completely solved.
