(Firefox :: General, defect)

Description

[Peter Buzanits]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; de-DE; rv:1.7.10) Gecko/20050717 Firefox/1.0.6
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; de-DE; rv:1.7.10) Gecko/20050717 Firefox/1.0.6

If there is a page with an image tag, that has an empty src attribute (<img
src=''>) the page is loaded twice. This can be bad with scripts, that do
something they should only do once.

Reproducible: Always

Steps to Reproduce:
1. Make a script page with <img src=''> in it.
2. Put some code into it, that writes some text in a File
3. Look, if this text is written twice to the file.

Actual Results:  
the text is written twice to the file.

Expected Results:  
Load the page only once.

This is expected. A blank url is taken as relative to the current page and so
resolves to the same as the current page so mozilla attempts to load the current
page as the image.

It is of course only a GET request and the HTTP spec suggests that these are
never used to make any changes.
