614865 - Addon about window does not handle overflow very well

Status: VERIFIED FIXED

Build Identifier: 

If an addon has a very long title or has a lot of contributors credited, there are some issues in the addon about window that prevent all of the text from being seen. These issues can also distort the window.

To reproduce this, view the about window for Firebug and one of the Mozilla Labs Prospector addons.

Reproducible: Always

So you say, you don't see any scrollbars? Can you please attach a screenshot?

I do see scrollbars, but the problem is not in the scrollbars; it's in the fact that the scrollbars are in the way of the content. Sorry, I should have uploaded a screenshot in the first place.

Ok, I see. Same on OS X for both of those extensions. Dave, something we should block on? It's not primary ui but seems to be that this window doesn't layout content very well.

How did this behave on Firefox 3.6?

It stretched the dialog until all the text fitted. Which in some cases meant that the dialog was larger than the screen.

Makes the addon name wrap if its too long. The icon was acting weird with max-height when the name wrapped, so its in its own container now. And a call to sizeToContent() because xul:dialog is stupid.

The weird scrolling issue with Firebug's about dialog is due to Firebug overlaying its own stylesheet for about.xul - probably in order to fix the issue described in comment 6. If you disable Firebug, and open its about dialog, you'll see that it works fine. I could potentially rename the CSS classes used in the dialog, but a better solution is for Firebug to not style the about dialog in 4.0 (or at least style in a way that doesn't break things).

Not really sure that these changes are necessary are they?

Otherwise r+

Without the extra container box around the image, I had some layout issue where the parent box's height was dependent on the image's max-height. 

Could I get a blocking+ on this? (or failing that, a+?) See comment 3 for how it breaks without this patch.

Might be useful to have a Litmus test with a long-named addon.

Blair, at least what I can see on OS X the scrollbars in the about window aren't shown correctly. There is no bar to drag. Is that intended?

[Blair McBride [:Unfocused] (UNAVAILABLE)]

Could you attach a screenshot?

Ah, that's Firebug's fault for breaking things. See the second part of comment 7:

Makes sense. Thanks for pointing it out. I missed that comment. Verified fixed with Mozilla/5.0 (Macintosh; Intel Mac OS X 10.6; rv:2.0b8pre) Gecko/20101212 Firefox/4.0b8pre

Blair, the only manual test we would need here is for wrapping a long extension name? Or do we also need to verify the scrollbars?

Just the long addon name.

Ok. Created a sample extension for that case, which can for now be found at:
