508536 - CTRL-F5 causes images to be downloaded multiple times

Status: VERIFIED DUPLICATE of bug 497665

(Firefox :: General, defect)

Description

[publicpp+mozilla]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.1.3pre) Gecko/20090803 Ubuntu/8.10 (intrepid) Shiretoko/3.5.3pre
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.1.3pre) Gecko/20090803 Ubuntu/8.10 (intrepid) Shiretoko/3.5.3pre

Hitting CTRL-F5 causes pages to load slowly because images are loaded many times. If same picture is referenced from 10 places on the page, then it is fetched 10 times.

I've verified it using FireBug Net module and using wireshark to inspect traffic.

Reproducible: Always

Steps to Reproduce:
1. Install FireBug (the bug is reproducible also without FireBug, so it is not FireBug bug)
1. Go to http://wikipedia.org/
2. Enable Net monitoring in FireBug.
3. Hit CTRL-F5.
Actual Results:  
Observe that image: http://upload.wikimedia.org/wikipedia/commons/b/bd/Bookshelf-40x201_6.png is being downloaded more than once.

Expected Results:  
The image http://upload.wikimedia.org/wikipedia/commons/b/bd/Bookshelf-40x201_6.png should be downloaded once, like in Firefox 3.0.

Tested on Linux and Windows versions of FF3.5
