682768 - Windows symlink breaks firefox cache

Status: UNCONFIRMED

(Firefox :: General, defect)

Description

[Julian]

Config
- all addons and extension disabled (new profile)
- firefox profile on C:\Users\username\AppData\Roaming\Mozilla\firefox\Profiles\zywdfqml.noAddons
- created a symlink with sysinternals junction at "firefox" to put the profiles on a different harddisk
- this setup worked long time (as far fas i can remember: working on firefox 1.xx to 3.5; broken since firefox 4.01 to 6)

What did you do?
- started firefox having 30 tabs open in the last sessions

What happened?
- about 50% of the open Tabs generate a "File not found" on restart

What should have happened?
- all tabs should fully load.

Solution
- disable cache completly
- remove symlink
