Years ago, Opera has been my main browser and I really liked it. Back then, it was the only browser (to my knowledge) that had tabs. It was a novelty back then. Over the time they added more features, like the conversion tool. Then they added more features I didn't need or want, like the side bar, and it quickly became bloated. I switched to firefox, which offered a greater variety of add-ons. I still use firefox as my main browser. The only thing I miss is the conversion tool. There is nothing comparable like the one Opera has built in. I later learned that the original developers sold it to a chinese consortium. In hindsight, that explains the constant changes to the worse, which pushed me to another browser.
