768890 - Tab content reloads separately everytime

Status: RESOLVED INVALID

(Core :: General, defect)

Description

[[e-mail]]

Attachment: toggling_private_browsing_and_viewing_a_tab.png

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:14.0) Gecko/20100101 Firefox/14.0
Build ID: 20120624012213

Steps to reproduce:

Both scenarios below cause the same issue

Scenario 1

I saved the tabs on closing firefox
I reopened firefox

Scenario 2

I opened private browsing
And i moved back to normal cached browsing.



Actual results:

Now , tab content for one tab alone loads.
If i select another tab , the content in that tab loads with considerable delay ( atleast 4 seconds ) to load the tab page content



 


Expected results:

Since firefox is threaded ,
Tab content on start should have been loaded for the first open tab thread.
And Near by tabs' thread should start buffering the content by then , automatically 
So that user does not face the delay as told.

This is a preference setting in Tools > Options > Tabs.  See the "Don't load tabs until selected" checkbox.

If that's checked, then the buffering you ask for is not done to avoid using up network and memory resources unnecessarily.  But you are, of course, free to uncheck that checkbox if you want the opposite behavior.
