680001 - Lowering screen resolution should reposition browser window when restore session.

Status: NEW

(Firefox :: Session Restore, defect)

Description

[Kenyakorn]

User Agent: Mozilla/5.0 (X11; Linux i686 on x86_64; rv:6.0) Gecko/20100101 Firefox/6.0
Build ID: 20110811165603

Steps to reproduce:

I use the same FF profile for Windows 7 and Ubuntu Linux (Gnome). Ubuntu has 5 Desktops next to each other. So x-Coordinate of the window-position can be larger than screen-width. It seems the window postition is safed in the profile.

I close FF on Linux on screen 2 or 3, boot Windows 7 and restore the session there.


Actual results:

FF starts, but is completely invisible to me. I can still minimize and maximize it form the task-bar, but is always opens at a position in the right! Outside of the actual screen area!


Expected results:

The browser should be opened in the visible area of the screen. I would expect: if there is only one screen with a defined ressolution and the window will be positioned outside of it, to ignore the safe value and place the window on position 0,0.

Storing diffrent positions for different OS would also be possible.

How are you sharing your profile between Windows and Linux?

This problem happens only on Windows Build.
This _not_ happens ubuntu 10.40 and GNOME2.30.2

This problem persists since Firefox3.6.x at least.

Reproducible: Always

Steps to Reproduce:
1. Setup Monitor Resolution to hight value such as 1280 x 1024
2. Open Firefox and Several tabs
3. Resize the Browser to small size like 250 x 300
4. Move the Browser to upper right corner of screen
5. Exit the Browser (Alt > File > Exit), this also save sessions

6. Setup Monitor Resolution to lower value such as 800 x 600
7. Re-Open Firefox
8. Restore Previous Session (Alt > History > Restore Previous Session)

Actual Results:
The browser is put outside a screen and invisible.

Expected Results:
The browser should be repositioned inside a screen and visible.

You say this happens since Firefox 3.6.x -- would you care to provide a precise regression range? 3.6 is up to 3.6.20 now.

I say 'at least'.

That's not incredibly helpful. I'm asking if you can test this on earlier versions of Firefox to find out where it first started happening.

Thanks -- a very old regression indeed.

I used a FAT32 Partition for a few years. But since 3 months the profile is located on a NTFF partition. So it is accessible for both OS.

But what is the physical location? Firefox expects the profile to be located in a specific location on the system. These locations are different on Linux than they are on Windows.

Yes they are! But it works. Physically it is saved on a SATA HDD.

On Win7 it is monted at:
E:\Profiles\Firefox\

And On Ubuntu at:
/media/EXCHANGE/Profiles/Firefox

I used the Profilemanager of FF to direct it to the same location.

2 ways to solve this:
1. check available screen size before opening windows (would solve the secondary windows). This could happen in session restore, but (personally) feels better suited for widget/windowwatcher code.
2. check available screen size before moving windows (would solve the first window case)
