Firefox displaying lower pane containing markup fragments

[Eugenia Loli-Queru]

After about 400 packages that I installed on Ubuntu from your repositories,
and some minor changes to the firefox prefs (same I do everywhere), I now get
this "class="t" strip that I can't get rid of:

[Matt Zimmerman (mdz)]

This sounds like it might be similar to this upstream bug:

http://bugzilla.mozilla.org/show_bug.cgi?id=247066

but I can't view the image there. Try the instructions in that bug report.

Was this an upgrade or a clean install?

[Eugenia Loli-Queru (eloli)]

I just use the firefox that came installed wiht your OS. I installed your OS
yesterday.

All I did since then is to install some mozilla stuff, mozilla dev, epiphany
etc. from your own repositories.

[Matt Zimmerman (mdz)]

In order to fix this bug, we need to be able to reproduce the problem ourselves;
I have never seen this happen.

Please list exactly the changes you made to the firefox preferences, so that we
can check if the same thing happens when we repeat your changes.

[Eugenia Loli-Queru (eloli)]

Hah, I found the bug!

The problem ONLY appears if you launch Firefox from the desktop! If I launch
it from the panel or the menus it doesn't have the bug!

Click on Apps/Internet and DRAG-n-DROP Firefox icon to the desktop. Launch
Firefox, and it creates that "class=t" problem!

[Matt Zimmerman (mdz)]

I just tried that here, and it doesn't happen. Could it also be related to the
preferences that you changed?

Has anyone else seen this bug?

[Eugenia Loli-Queru (eloli)]

[Matt Zimmerman (mdz)]

Did you install any mozilla software which did not come from Ubuntu (such as
extension modules)?

[Eugenia Loli-Queru (eloli)]

I installed Epiphany and whatever comes with it as deps.

[Matt Zimmerman (mdz)]

Please try the instructions in the upstream bug report, as requested in comment
#1 and report the result

[Eugenia Loli-Queru (eloli)]

Sorry, I have now upgraded to Mozilla 1.0PR (I need to actually use the
machine instead just testing things), and the problem went away after re-doing
its desktop launcher by hand (instead of DnD it from the gnome menus).

[Thom May (thombot)]

Can't reproduce with 1.0PR, closing

[Eugenia Loli-Queru (eloli)]

The bug happened again, even with Firefox 1.0PR. Bug is now reopened.
No, I can't try what is suggested on #1, because these instructions are for Windows.

Again, the bug only happens when Firefox is executed from the desktop. If I
execute from the menus or gnome-panel, the bug doesn't happen.

i am attaching a shot, see the bottom of Firefox for that weird "class=t" thing.

From your comments, you're not using our package of mozilla 1.0PR. If this is
the case, then you should report this bug upstream. If it is not the case and
you have mozilla-firefox-0.99+1.0PR-0ubuntu3 installed, you'll need to attach
the launcher file in your ~/Desktop for firefox.

[Eugenia Loli-Queru (eloli)]

We don't seem to understand each other. The bug happened since the day 1,
since I was using YOUR firefox. Only later I decided to upgrade just in
case the bug would have been fixed. But it wasn't. The bug happens on all
firefoxes but I only have the problem with ubuntu.

[Thom May (thombot)]

OK. Please test the firefox currently in ubuntu. If you still have a problem,
please attach
the launcher file.

Still can't reproduce using your desktop file.
Can you try moving your .mozilla out of the way and see if the problem persists?

[Eugenia Loli-Queru (eloli)]

Yes, this fixes the problem. It seems that Firefox can corrupt its files under
some conditions.

[Thom May (thombot)]

Firefox doesn't like upgrading profiles at all, film at 11. :(

[Eugenia Loli-Queru (eloli)]

Thing is though, the bug existed since day 1, since I installed Ubuntu. I had
NOT upgraded any profiles, it was a clean installation, and yet, the bug existed
after changing some preferences (as described above).

[Thom May (thombot)]

Sorry, but this is not a bug. At no point have we been able to reproduce it, and
given that you admit
that you've both changed defaults and can only reproduce it by doing things we
don't do in our default
desktop, it's very hard to see a solution. I suggest that you contact upstream
about this, probably in the
bug already mentioned here.
