Status: VERIFIED DUPLICATE of bug 438909

(Firefox :: Bookmarks & History, defect)

Description

[Jens Schröder]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; de; rv:1.9.0.1) Gecko/2008070208 Firefox/3.0.1
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; de; rv:1.9.0.1) Gecko/2008070208 Firefox/3.0.1

Sometimes the context menu on bookmarks comes up with the top three entries disabled (see attachment). Then it is not possible to choose on of those entries: "Open", "Open in new window" and "Open in new tab". If you try to right click on a bookmark again those items are activated for clicking (no longer disabled).
This happens mostly, when I switched from another application to firefox.
I noted this only since Firefox 3.0. With 3.1 the problem is also included.
Is it a focus problem?

Reproducible: Sometimes

Steps to Reproduce:
1. Switch to firefox.
2. Right click on a bookmark. Can also be a bookmark in a bookmark-folder.
Actual Results:  
Sometimes the top 3 menu items are disabled.

Expected Results:  
The top 3 menu items should be active.
