284286 - Tabs loading in background forced to foreground

Status: RESOLVED INVALID

(SeaMonkey :: General, defect)

[David Hagood]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8a5) Gecko/20041121 MultiZilla/1.8.0.0a
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8a5) Gecko/20041121 MultiZilla/1.8.0.0a

Tabs that are loading in the background are forced to foreground.

This only started when I switched Multizilla's Javascript blocker from "Block
all" to "Ask".


Reproducible: Always

Steps to Reproduce:
1) Install Multizilla, configure Javascript permissions to "ask".
2) Open a page with links to pages on other servers that use Javascript: for
example, open news.google.com, and locate a link on www.cnn.com.
3) Load a link to another site which uses Javascript in the background.
4) When Multizilla brings that tab to the foreground and asks "Allow (site) to
load Javascript" - indicate NO and "Remember this". Repeat as needed until the
site loads.
5) Close the newly-opened tab and return to the first tab (google).
6) Once again, load the link to the second site in the background.

Actual Results:  
Site will start to load in the background, then be forced to the foreground.


Expected Results:  

Site will now load in the background (unless a new ad site is inserted requiring
a new Javascript prompt).


I conjecture that the Javascript blocking code is forcing the tab to the
foreground because it "might" need to generate a dialog, rather than waiting
until a dialog is actually needed.

Additional data: this behavior ceases (Mozilla operates as expected) if the JS
pref is changed from "Ask" to "Block".

The regulars at b.m.o. will not normally accept problems relating to
extensions.
