Can attach a testcase (using the 'Add an attachment' above) illustrating this ?

That testcase renders fine here, on any version of Gecko. The 3 lines are centred and the element use the full width of the body.

Have you tried disabling add-ons, user stylesheets, etc ?

I disabled all plugins, without effect.

However, after I restarted my computer, I discovered that the problem was gone, even with the plugins enabled. Since then, I have not been able to reproduce the problem.

It seems to have been a temporary error, and since it wasn't a severe problem to begin with, I mark it as resolved.
