Netscape Communicator was awesome until AOL came in and destroyed Netscape. By then Mozilla had already gotten out and gone their own way with Mozilla Suite and other projects such as the FireBird (renamed to FireFox due to patent and name conflicts)

The spirit of Netscape Communicator is not dead. It's called Mozilla Seamonkey (renamed from Mozilla Suite to fit the naming of projects better)

bumped for FARMFOX 3.6 (the 3.6.6 upate which skipped 3.6.5 completely had only ONE bugfix and it was mainly because of complaints from Farmville players /the plugin timeout was increased because FF was closing Flash etc. too early because of the time limit for hanged plugins. The game loads maybe a bit too much at once and the plugin appears unresponsive for a while and goes over the limit a plugin is allowed to be like that. Solution: Increased time limit. Though the problem is perhaps at the other end.

Oh and the game is a cr*ppy casual game from facebook. If it didn't have so many players Mozilla wouldn't have given a s**t. Those users barely even know what a browser is anyway and they'd only use it for something silly like farmville and checking their e-mail. While the least competent, their numbers and demands are somewhat formidable. They expect things to just work and they hop from software to software on a mere whim.

3.5.13 / 3.6.10 released within a week of the previous one fixes a potential crash in updater under certain cir tances.

Notice that Firefox 3.5 support/development is ending. It was set to end in August and 3.5.13 is only a quick fix for 3.5.12 that was built in august.
