From the Firefox for Nokia N900 1.0 release notes themselves, stumbled upon this little gem:
Initially, Firefox for N900 does not support browser plug-ins. Due to performance problems using Adobe Flash within Firefox on many websites, especially those with multiple plug-ins on them, we have disabled plugins for Firefox for Maemo 1.0. We plan to provide a browser add-on that will enable you to selectively enable plugins on certain sites, because some sites, like YouTube, work well.
So the good folks of the Mozilla Foundation have gone and released the thing. Given the recent turn of events, it’s interesting to see the reality brick hitting the Adobe head, so to speak. Couldn’t think of a more appropriate support for the Apple iPad, really.
Even if the eventually release it with plug-in support enabled, they will probably stick with letting users enable Flash selectively… This is yet another nail in the Flash coffin.
