Use HTML context menus in about pages


(Firefox for Android :: General, defect)

Not set



Firefox 21


(Reporter: wesj, Assigned: wesj)




(4 files)

We should use HTML5 context menus in our about:pages and remove the dependency on digging into browser.js there.
This fixes about:apps.

This was more complex and exposed a problem in the implementation where a page can't hide context menu items in the popupshowing or contextmenu events (as we've already build the menu at that point while trying to make sure we had something to show).
Attachment #698958 - Flags: review?(mark.finkle)
About:addons actually didn't have context menu handlers. This makes it so it does with options for "Enable/Disable" and "Uninstall". I also fixed row highlighting when you tap on them and some inappropriate ("Save image" type) context menu items that appear when you long tap on the icons.

Can we (Should we) null out target in the context event handlers (addToHomescreen and uninstall) as a safety check? Maybe it's overkill?

var? Are you a webdev? :)

nit: Add a blank line before the second "return"

>+        if (val)

nit: Add a comment (and a blank line) before this check letting us know that hidden menus will be null

In the last patch you change the entities to match the other strings in the DTD file. Here you keep the same entities as were in the properties file. L10N might also like the entities to change.

r+, but I want Biran to take a look at the heart of the aboutDownload.js changes

If the user clicks outside of a download entry, won't this climb up to the root node and eventually throw an error from a null If so, you should add a null check inside the loop so it can return early.

Patch 2/3 for Aurora

[Approval Request Comment]
Bug caused by (feature/regressing bug #): bug 736321

Testing completed (on m-c, etc.): landed on mc today
Risk to taking this patch (and alternatives if risky): pretty low risk. Not a widely used feature on the web, but useful. Required for desktop parity.
String or UUID changes made by this patch: None.

We don't think this is a particularly critical issue for our users or web developers. We think this can ride the trains.
