Extra functions that make it stand out, and potential for extendability.
pera, Brave
and Edge integrate AI assistance. In each case, the AI window can pop out of a sidebar for quick O access. This makes sense as you’re typically trying to get to the bottom of a subject that is dominating the current window. As with all AI chat, quality and factual accuracy is a roll of the dice.
When playing video, Opera can activate its Lucid mode and enhance the video quality. Flow is another good example of the type of extra feature that Opera throws in. It’s for sharing notes, links and files between devices while you’re browsing.
Chrome
and Firefox both have hundreds of extensions created specifically for each – though Chrome has started to lock down on these. So, if there is a feature that you need from another browser, you can almost certainly add it. For example, neither makes much use of its sidebar but there are many sidebar addons. On the downside, you have to sort through all the extensions, add and configure them.
Brave, Opera
and Edge have their own extensions, but as they are partially based on Chromium, many Chrome extensions work within them. The rub is that there is no guarantee that a Chrome extension will work fully or predictably in those browsers.
