firefox doesn't work properly after an update

[Mathieu Fontaine]

Binary package hint: firefox-3.0

Description: Ubuntu 8.10
Release: 8.10
My current version of firefox is 3.0.5.

The Ubuntu package manager propose to me to install the 3.0.6 version. But after the installation, firefox doesn't work properly. Every new tab I open give me a beautiful message "Assertion Failed" (see the attachment). The message appear when I retype the same or another url in the address bar in this new tab. Otherwise all the present tabs (which did already open) can be used properly (with F5 or by clicking on links in the page, but not if I press enter in the address bar)

The Ubiquity plugin crashes the same way. When I press the shortcut, another error message appear (but I can't submit it, the form accept only one attachment).

The add-ons window (Tools > Add-ons) doesn't appear properly neither. The window fits 1x1 pixels, and when I resize it, the window is blank!

The search bar is completely broken!!

However the button "Help > Report a Problem" works properly, so I can report the problem right now.

In brief, firefox become completely unreliable just after an update, and I know all these bugs disappear after restarting firefox (I already detected this bug in the past), but can't we find a solution to avoid all these bugs (how can I do if I don't have to restart firefox right now)

PS: sorry for my poor english.

Caused by not restarting firefox properly after update
marked as a dupe of bug 338785

John, I'm not sure that this bug is a dupe of bug #338785.
In his bug, Rilium said he had to restart completely his computer to get firefox work again.
For me, restarting firefox was enough.

I'm aware that this bug can be not considerate as a bug because we are warned to restart firefox just after an upgrade.
But can't we expect to be able to work in good conditions until the next firefox restart ?
For me, after an upgrade, we have two solutions :
- either we are "forced" to restart firefox to be able to go on,
- or we can go on without restarting, but also without bugs.

For now, Firefox permits to go on without restarting after an update, but in an unstable way. That can be frustrating.
