Lately I switched from Firefox to Chrome. Here are some of the extensions that I recommended:
- ScriptNo extension filled in for the Firefox Noscript. Another good extension is
- Cloud Save for saving images and files to your cloud storage (Google Docs, Sky Drive supported)
- Gmail Attachment to Docs for saving attachments in gmail to Google Docs instead of saving via your PC
Another good desktop app is Gladinet which map you cloud storage (Amazon, Google Docs, Sky Drive, etc) to a local drive which is very handy for me.
