Firefox Problem After Upgrading to Ubuntu 8.10 (From 8.04) 0

After the smooth process of upgrading my Ubuntu from Hardy Heron (8.04) to Intrepid Ibex (8.10), I happen to notice my Firefox (version 3.03) starts to behave differently. For instance, Firefox’s toolbar always returns to the default layout and some of installed add-on icons do not appear even they are functioning properly.

After some trials and errors, I eventually found the culprit that is causing this strange behaviour: Ubuntu Firefox Modifications (version 0.6) add-on. Once it is disabled, Firefox behaves like normal. I suspect a newer version of this add-on is needed for the new Ubuntu 8.10, however I’m still yet to notice any problem after disabling it…
