It should actually work with firefox by using TamperMonkey extension. I'll update the instruction on how to make it work on Firefox

You should be able to just load the script file in a userscript manager for firefox.

According to the original link the URL for the script is https://raw.githubusercontent.com/jorgefsilva/beatthatwall/m....

Despite the name, https://github.com/iamadamdev/bypass-paywalls-chrome supports both Chrome and Firefox.

Since the Firefox installation is an .xpi file, I assume it's also blocked by Mozilla? Not saying I'm surprised, though, giving the nature of the extension.

Not sure, perhaps the author of that one just hasn't tried to get it approved. There's also https://addons.mozilla.org/en-US/firefox/addon/bypass-paywal... and a number of other ones for Firefox that don't look to be blocked, so I don't think Mozilla is taking the same stance.

i use that........ on firefox ever since it first came out
