This is even worse. You can't trust either Mozilla or Google to vet the extensions they publish for spyware. So you have to trust and/or verify that this extension does what it says and no more. But worse, you have to vigilantly watch the extension for any changes, even if you trust the developer today he may sell it to a spyware company at any time.
This is an open source extension, as stated in the description on both pages. The repository is linked in both, feel free to build it from source and install it locally.
You don't even need these extensions, you can set up a redirect rule in uBlock Origin (if you trust that).
I sent these extensions to remedy the stated need to manually rewrite the URL, I did not say that using these extensions is a better solution than Reddit turning off the Fuck You pattern.
To install an extension locally in Firefox you have to be using a special build or jump through other hoops. All of this goes back to the point; that Reddit is employing the "fuck you" pattern when they force you to jump through such hoops to use the version of their website that actually works.
What platform are you using to write this very comment? If it is open source (Linux etc.), have you gone through the millions of lines of code for each program installed on it?
