Description Jiri Dluhos 2006-03-10 14:04:01 UTC

Sometimes, when Firefox is rendering a complex table, some of its items are not correctly placed, as if the process of layouting was stopped prematurely. (Please see the attached screenshot.) After reloading, everything works fine.

This problem appears pretty rarely, but when it appears, it seems to be reproducible by pressing Back and Forward (reloading the page multiple times seems not to provoke the bug).

The screenshots were done on my page with LSB testing results; it seems the large table on it helps triggering this bug:

I think the best chances of reproducing this bug are when opening a new empty tab in Firefox, copying the URL to the address bar, and hitting Enter/clicking Go. Simple opening of the URL in a new tab does not trigger the bug so well.

If you resize the window does the glitch go away?

Comment 6 Jiri Dluhos 2006-03-13 10:49:15 UTC

No, the table is still rendered incorrectly even if the window is resized.

Comment 7 Jiri Dluhos 2006-03-13 12:39:08 UTC

Oops. It seems that the glitch is not caused by Firefox itself but by the Adblock+ extension (I had it installed on my workstation with the previous system, and it apparently was preserved through the update to Beta7).

After disabling Adblock+, the table is rendered correctly on the first try :-)

So, I propose closing this bug as INVALID.

thanks for figuring this out
