Package: iceweasel
Version: 3.5.8-1
Severity: normal
Bug reported on https://bugzilla.mozilla.org/show_bug.cgi?id=551678
and reproducible with -safe-mode.
When using manual window placement (fvwm's ManualPlacement, a.k.a.
active placement), Firefox doesn't track the mouse correctly. For
instance, it may think that the mouse pointer is still over the tab bar
while it is no longer over it, yielding buggy behavior. See steps to
reproduce below: this is always reproducible in safe mode.
Reproducible: Always
Steps to Reproduce:
1. Choose the fvwm window manager with ManualPlacement (steps 6 and 7
below are part of manual placement): Style "*" ManualPlacement (in fact,
I've tried with ActivePlacement, but ManualPlacement should be better to
reproduce the bug on some configurations).
2. Run: firefox -safe-mode
3. Open a web page that has links (optional, depending on whether the
current web page is OK or not).
4. In the menu bar, click on "Tools". Make sure that the "Error Console"
item appears partly over the tab bar, otherwise the bug may not be
reproducible.
5. Click on "Error Console" (the mouse pointer must be at the tab bar
level).
6. Move the mouse pointer to position the error console over the
document area (web page). What's important IMHO is that when the
error console appears, the mouse pointer isn't over the tab bar.
7. Click with the left button to make the error console appear.
8. Move the mouse pointer over the links of the web page.
Actual Results:
When the mouse pointer is over a link, the correct behavior (arrow
replaced by a hand, URL appears in the status bar) occurs for a fraction
of second (hardly visible), then the mouse pointer is changed back to
an arrow and the URL is replaced by "Done" in the status bar, as if the
mouse pointer were moved to an empty area (or to the tab bar).
Actually, when testing this with the Tab Mix Plus extension, a close
button may appear over some tab, suggesting that Firefox thinks that
the mouse pointer is still over the tab bar (at the position where the
click over the menu item was done?).
This buggy behavior stops once one moves the mouse pointer to the
tab bar, then back to links on the web page.
Expected Results:
When the mouse pointer is over a link, the arrow should be replaced by
a hand and the URL should appear in the status bar.
FYI, here's how ManualPlacement is described in the fvwm man page: The
user is required to place every new window manually. The window only
shows as a rubber band until a place is selected manually. The window is
placed when a mouse button or any key except Escape is pressed. [...]
