Status: RESOLVED INVALID

(Firefox :: Downloads Panel, defect)

Description

[AliN]

User Agent: Mozilla/5.0 (X11; Ubuntu; Linux i686; rv:21.0) Gecko/20100101 Firefox/21.0 (Beta/Release)
Build ID: 20130512193902

Steps to reproduce:

Some about-pages such as about:downloads, about:addons, about:preferences, about:permissions remove toolbar, so you can’t see download progress when they are active. 
First, in about:config change browser.tabs.onTop to false in order to have the toolbar in all about-pages. Then open one of the above about-pages and click on the download panel icon on the toolbar.


Actual results:

The download panel crashes and top toolbars are removed. Opening a new tab will return the toolbars, but the download panel remains crashed and shows nothing in that window.
After then opening one of the above about-pages in the same window will remove the toolbars. 
Download panel will work in a new window. 


Expected results:

The download panel should apear as always does.

What exactly do you mean by "download panel crashes"? Can you add a screenshot? And, does this problem happen on a new profile and/or if you restart with add-ons disabled (there's an option to do this in the help menu)? Thanks!

Yes, I just wanted to mention the problem exists with (manually) disabling all add-ons, but not in safe mode (restart with add-ons disabled).

It would still be nice to have a screenshot. Could you also check if you can see any errors in the error console? (There should be a menuitem under Tools; but it's possible you may need to open about:config and toggle the devtools.errorconsole.enabled pref so its value is 'true')

I’m using Firefox on Ubuntu, so just tried to reproduce the bug on Lubuntu and both Ubuntu live and guest user – it doesn’t occur.
I’ve had Download Panel Tweaks add-on, so installed it on other modes to see if it’s related to the bug – it’s not.
Seems it’s because of my personal settings. I may need to reset Firefox.

Ali, are you still experiencing this issue?

No, after a Firefox reset I couldn’t reproduce the bug. I couldn’t find the reason as well.
