Just to confirm that our testing of firefox 10.0.3 ESR shows no odities which are not also present in the mozilla upstream releases - and mostly on other platforms too. Apart from local weirdness in how I test things, the only issues which are likely to affect people are: More fun than usual overriding the default homepage (putting browserconfig.properties with the new setting inside omni.ja and pointing at that from a .js file) A few settings changed (or are new with defaults which have different behaviour) so existing firefox 3.6.x profiles might looks slightly odd, but then our default config was probably non-standard anyway so it might just be us... Printing defaults to losing the header/footers - at least on iso_a4 paper. A bit of research on the last of these suggests that this was broken in firefox 6 (July last year) and has apparently not been fixed yet. https://bugzilla.mozilla.org/show_bug.cgi?id=675457 My current workround is a nasty hack - adding info for *every* printer into a .cfg file. It is ugly and needs to be regenerated (at least when the set of printers changes) but avoids having to explain the operations needed to pick up the right values to some of our less cluefull users :-( I've just started doing some testing with the new thunderbird 10.0.3 ESR, and so far the only weird thing I've found is an annoying sequence of messages about langpack-en-GB (it says it wants to remove/disable it, and then it tells you it is available to be added). With a new/clean profile it just silently adds it. I really don't understand the newer extensions stuff or some of this might make more sense to me. -- /--------------------------------------------------------------------\ | "Computers are different from telephones.
