Status: RESOLVED WORKSFORME

(Firefox :: General, defect)

Description

[Tony Mechelynck [:tonymec]]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.8) Gecko/20050517 Firefox/1.0.4
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.8) Gecko/20050517 Firefox/1.0.4

After doing "Save image as..." the contents of the URL bar are sometimes
replaced by the value chrome://downloadmgr/content/downloadtab.xul which
corresponds to the download manager. The contents of the window are however OK.

Reproducible: Sometimes

Steps to Reproduce:
1. Browse to a page with a large picture in it.
2. Click right on the picture.
3. Select "Save Image As...". A file dialog appears.
4. Click "Save".
Actual Results:  
The contents of the URL bar were replaced by
"chrome://downloadmgr/content/downloadtab.xul" (without quotes), i.e., by the
"chrome" URL of the download manager.

Expected Results:  
URL bar shouldn't have changed, still showing the URL of the HTML page
containing the image just saved.

I'll attach a screenshot when I come back to the bug after filling out this form.

This is an intermittent bug: it doesn't appear every time. I believe that it
appears more often when saving large images.

I suspect a race condition.

When I use the "Save Image As..." dialog, one of the following can happen:
(a) The contents of the download manager flash by for a fraction of a second,
temporarily replacing the current page contents. Contents and URL of the page
are restored. (Bug is not manifested)
(b) The favicon of the download manager (on a different tab) is replaced by the
throbber for some time (let's say on the order of 1 second) but the currently
displayed page stays put. URL of the current tab may be replaced by chrome URL
of download manager (expressing the bug).
(c) The favicon of the download manager (on a different tab) is replaced by
itself so fast that I don't recognise a throbber in its stead. Bug is not
manifested.

I'm not sure, but I suspect the timing of loading the image from cache or from
the net may have an influence on which one happens among (a), (b) and (c) above.

Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.8) Gecko/20050527
Firefox/1.0.4

With the JavaScript console on, "Save Image As" gives the following errors:

Error: Components is not defined
Source File: chrome://downloadmgr/content/browser.js              Line: 313
(6 times), then
Error: aContent has no properties
Source File: chrome://downloadmgr/content/downloadtab.xml         Line: 282
(twice).

The image is saved and the page contents stay the same, but the Location Bar is
changed to chrome://downloadmgr/content/downloadtab.xul

Sorry, I'm not using Firefox at the moment because some extensions have stopped 
functioning properly (acting at cross-purposes I guess; until I can investigate 
the matter I'm using Opera) and also because of the memory bugs 174604, 249469, 
268138, etc. If someone else sees this bug, please comment.

Tony, are you able to reproduce this bug using Firefox 2.0.0.3 or later with a clean profile? There's a good chance that this bug was caused by an extension.

Sorry, I'm on Linux now, and I haven't seen this bug anytime recently. Looks like it never was "systematic" anyway.

=> WFM. "Anyone sees it, please reopen."
