yep, for once I'm forced to agree with abill_uk, it's incredible that ovi/mozilla can have made it so hard to get the new version of firefox installed on the phone (in my case anyway).

I already had firefox 1.1 installed (got it from OVI). I also had the ovi & mozilla repos enabled, from when I did that install. Got no indication of any updates available, so when I saw the news of V4 on "The Register" today, I followed the link to the mozilla website and clicked on the maemo download. This added a new mozilla repo, and then tried to install v1.1 (again) for some reason, so I cancelled.

I then remembered that I'd originally installed via OVI. I went to OVI store and checked firefox - sure enough, it is now offering "Firefox 4 for Maemo". I clicked to download it and this brought up app manager - but did nothing further. I then uninstalled my existing ff and tried again and this time it offered to install firefox 1.1 (again). I then disabled the OVI repo and the old mozilla repo, and tried to download via the mozilla download link again - but still no joy ... after getting the "mising package" for fennec, I re-enabled the ovi repo and yet again got offered v1.1.

I finally found the V4 .deb on the mozilla website (as per Travla's link), downloaded that and it installed fine.

Reckon I wasted about two hours farting around with the app catalogs, and removal/install attempts in the ever-speedy App Manager. grrr.

Finally fired up the new firefox browser only to find it is at best "meh", particualrly after having played with Opera 11 for a couple of weeks. Sooo not worth the effort I'm afraid, it starts so slowly that I lost the will to live explore. Will bno doubt give it a proper try once I'm less p!$$ed off but for now sync is the only advantage I can see ... and that ain't enough for me to fire it up on a regular basis :-(
