I'm not affiliated to Facebook in any way and non-native English speaker. Sorry if this sounds so offensive, I'm just becoming tired of people complaining about Web-Apps. Probably your problems solve by getting a better computer and a better network connection, or by removing some of your Facebook friends and deactivating Facebook Apps.

When using Gmail at work often, I frequently failed to sent attachments or I had issues with the mail client to load. Others had the same issue. It's always a question how you use applications.
