The first beta of Firefox 3.6 is set to arrive on Tuesday 13 October.
The Register noted an exchange in Google Groups, which detailed the timetable for the beta and what changes it will feature.
The code is set to be finalised this week, with testing over the weekend.
Mozilla's Mike Beltzner admitted that the timetable could shift, but said developers shouldn't worry if that happens. "There is no shame," he said.
Firefox 3.6, which is codenamed "Namoroka", is set for release before the end of this year. It's not a major upgrade, but will tweak the JavaScript engine and upgrade the look of the browser, among other new features.
After 3.6, Mozilla will release Firefox 3.7 early next year, with major update Firefox 4.0 due out in the second half of 2010.
