Did I miss something? I mean, I really haven't read anything about android sales surpassing iPhone sales. Don't get me wrong, it would be cool and everything, but I just don't see it happening.

It's not the memory of spawning new processes, but the fact that you need to have the browser runtime in the memory of each of the new processes.

If firefox is using userland threads, then the library they use must only be able to use one OS thread. This is a disadvantage in a computing world where desktop cores seems to be increasing in number and decreasing in power. Using a separate thread for each tab might be more trivial than trying to make the userland library OS thread aware.

I'm really hoping that separating the tabs will help with memory leaks. Although there is a cost of memory using separate processes, the leaked memory will close with the tab and not stay for the entire session.

This is not censorship. The leader of the protest had the authority to do what they did, which under the circumstances was probably a good idea, as they were trying to use the protest for their own ends.
The anti-immigration group also has the power to hold their own protest, for their own ideas. So there is no way you can call it censorship.

For most people, a word processor is a fundamental part of the operating system. Some people also do not have access to the internet. This means that there WILL be some people who want to use a word processor before they are able to access the internet, which means they won't have a change to download open office or be able to use google docs. This is why an off-line, light weight alternative should be included.
