Userscript to turn any instance of "He/She" on a web page to "They"

This script replaces any instance on a web page of "He/She" or "He or She" to "They". The code can recognise instances of "he or she is" and replace them with "they are" to maintain grammatical correctness. Other contextual differences can be recognised and replaced accordingly.

You will need a userscript manager. I recommend Tampermonkey.

Once you have Tampermonkey installed, follow the images below to install the script.

There may be rough edges and instances where this extension many not work. If that this is the case, either create an issue or submit a pull request with edited code.

The script doesn't function correctly at all if a string in the body contains any capitalisation
