As with Firefox 3.5, there's improvements to the performance, pages render faster,
carries the code name "Namoroka" Alpha 1, and it is also currently referred to as Firefox.next. And like other
Firefox Alphas, it does not bear the Firefox logo.
This release uses the Gecko 1.9.2 engine and includes several interface improvements, such as new graphical
tab-switching behavior, which was removed from 3.5 with Beta 2. Although, the new tab switching behavior is
off by default. To enable tab previews, set browser.ctrlTab.previews
You can also switch to the previously used tab for this new behavior, set browser.ctrlTab.mostRecentlyUsed
Several new features Namoroka / Gecko 1.9.2 Alpha 1 introduces, as listed by Mozilla:
1. Compositor (Phase 1), which moves Gecko to using one native widget per top-level
See this blog post
or bug 374980
for more details.
2. A new focus model, described here
and tracked in bug 178324
3. The chromedir
attribute has been replaced with a pseudoclass
4. Several new CSS3 properties including background
and gradients for background images
6. Startup and responsiveness improvements throughout the application.
As for feature 6, the start up time is much faster, we timed 3 seconds. And the responsiveness is fantastic,
we tested Firefox 3.6 Alpha 1 with some "Chrome Experiments" and Firefox responds much faster to most of them.
Where in Firefox 3.5, many of the "Chrome Experiments" ran very slow, some times bringing Firefox nearly to a stop.
As with responsiveness, if you happen to run into a situation where Firefox slows down, in Firefox 3.5, you might find
it difficult to even close the Tab that is slowing Firefox down. Well in Firefox 3.6 you can easily close the Tab,
and Firefox will quickly recover and speed right back up.
There is better autocomplete recommendations for form fields, no longer in alphabetical order, they are sorted by
frecency, so the proper values are displayed. Also, the characters you type are searched in all previously entered
strings not just the beginning as in Firefox 3.5.
There seems to be not much improvement to how page rendering is done, Firefox 3.6 Alpha 1 scores a
94/100 on the Acid 3 test, up from 93/100, with a pause at 26/100 and 27/100.
