Just checked and saw the Looking Glass add-on installed on my work laptop. I've uninstalled Firefox and will be removing it from all of my computers. I had just started slowly migrating back to it with the performance enhancements in the latest update, but honestly I don't think I can get past a breach of trust at this level.
Are you switching to Chrome, the browser that sends your every keystroke back to HQ?
Google does track a lot of my data but they provide useful services in exchange, and in addition they make it pretty easy to see what data they have on me. Also Google's data is its competitive advantage so our interest in protecting my data from 3rd parties is aligned.
In short, Google tracks me sure, but they're pretty transparent about it. I do think some of the things Google does with Chrome and it's market position is less than stellar so I'm still exploring other options. If you have any suggestions I'd be happy to hear them.
