315029 - data-URLs get obfuscated in View Source window

Status: RESOLVED DUPLICATE of bug 235344

(Toolkit :: View Source, defect)

Description

[Veronica]

User-Agent:       Mozilla/5.0 (X11; U; FreeBSD i386; en-US; rv:1.8b4) Gecko/20050910 Firefox/1.4
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8) Gecko/20051025 Firefox/1.5

Data-URLs are like:
<img src="data:image/jpeg;base64,<encoded-image-data>" />

Thus the image binary data is embedded in the HTML code, per HTML 4.0.1 recommendation. When viewing source on these pages with Firefox 1.5RC1 (and beta2), all you get is <img src=<loooooooooooots of spaces> alt="" />.

To fix this bug, i would suggest to cache the exact data the HTTP server sends you. Now i see lots of moz-blah embedded which surely didn't get sended by the HTTP server. View Source is used for debugging the EXACT source code - so please don't touch even a single byte. Only syntax-highlighting (colours) is useful IMO.

Affected:
- Firefox 1.5 Beta2 and RC1 on Windows XP/luna

Not affected:
- Firefox 1.5 Beta1 on FreeBSD (custom built)

This may be a regression from Beta1 to Beta2.

Reproducible: Always

Steps to Reproduce:
1. Go to a webpage with data URL's
2. Right click on page, select "View Page Souce"

Actual Results:  
Instead of the img src, all there is is about 7000 spaces.

Expected Results:  
Display img src data, with every byte as-is sended by the HTTP server. View Souce is meant for viewing the data behind the page, not what Mozilla parses it into.

there's just 1 line with the image data with no spaces

This doesn't seem like a critical stop ship bug to me. How did 1.0 handle this?

Seems like a low-impact issue that will not block rc2.

If I reduce text size with Ctrl+-, the image source becomes visible at some point.
