Trying to make contributing to the Team Fortress Wiki a little better.
TF Wiki Sentry is available to download and install from the Firefox Add-ons site: TFWikiSentry.
To enable this extension on Google Chrome, you will need to visit chrome://extensions/, activate "Developer mode", select "Load unpacked" and point to the cloned/downloaded repository.
Just be aware that Google Chrome will keep bugging you because you enabled Developer mode. It's really annoying, so please download a different browser.
While not tested, this extension should also work with other Chromium-based browsers with little to no tweaks.
