Browse the Free version of the web with Redirector!
Making the good practices automatic is a good thing, and up until shortly, I used to manually substitute the original prefixes, in a more or less tiresome manner, prone to error. This all changed when I stumbled upon the Redirector Firefox extension, which does exactly that: substitute a URL fragment for another based on a set of rules. Couple that with frontends like Teddit, that subs in pretty nicely instead of Reddit, and you have a very smooth experience. Plus you can even apply it to things like iFrames, so an YouTube embed can cleverly become an Invidious embed with no change in the experience!
Thus, I highly recommend using this add-on for browsing the Tracking-Free version of the Web, or at least as tracking-free as it can get. You can see my simple example redirector file for an example on where to begin. Enjoy the freedom!
