Firefox introduced similar functionality in its former Test Pilot program, in 2018. It now lives on as an extension: https://addons.mozilla.org/en-US/firefox/addon/wayback-machine_new/ https://addons.mozilla.org/en-US/firefox/addon/wayback-machi... And here's the report: https://medium.com/firefox-test-pilot/test-pilot-no-more-404s-graduation-report-22e65f62b2b1 https://medium.com/firefox-test-pilot/test-pilot-no-more-404... Basically if you look at the results, they aren't so encouraging, because the archive has results for only ~20% of URLs that aren't found and when it does have results, a majority of the time users tend to dismiss or ignore the notification. Still, it's a useful extension that I keep installed in my Firefox. --- Adding something natively to the browser isn't a virtue, because the browser maker can have perverse incentives due to the nature of the business. I personally don't understand how some people can trust Brave for ad-blocking (given they are a company whose business model is still the serving of ads) instead of just installing uBlock Origin in their favorite browser, whatever that browser is. Speaking of uBlock Origin, even if you can install it on Brave right now, given Google is deprecating the underlying API in manifest v3, I don't think Brave will be able to support uBlock Origin for long, in spite of what they've claimed, simply because I don't think they have the capacity to diverge too much from Chromium's code base. And if you want Tor and such, might as well go for the real thing. -- > One thing I'd really like to see for Brave's mobile browser in the future is the ability to use Chrome extensions - it seems completely strange to me that this hasn't been implemented yet Well, it's actually rather obvious: 1. Brave is basically leeching on Google's work, they don't have the capacity for actual software development that goes beyond branding and features that serve their own bottom line — speaking of which, if you care about the health of the web, you're not sticking it to Google when using Brave, precisely because it's still Chromium, still contributing to Google's dominance 2. Extensions can go against their own business model and their interests here are actually aligned with Google's (yes Mozilla's interests are aligned with Google as well, but Firefox on Android does support extensions and given their culture and how things have evolved on the desktop as well, at least in this regard I'm pretty sure they'll support extensions for as long as the underlying OS allows it)
