The Greasemonkey extension for Firefox runs scripts in the context of the loaded documents. A few such scripts can be downloaded from the userscripts.org script repository.
This repository contains a collection of scripts - each directory contains one script and the related files.
Here are some scripts I wrote.
- TipMaster - Author Hightlight - Highlights the OP's and own messages in a thread.
- TipMaster - markItUp Setting - Improved settings for the markItUp! editor.
- TipMaster - No Old New - Remove the NEW icon from the old posts.
- TipMaster - Profile Card - Display brief profile information on mouse over the member profile link.
- TipMaster - Reply with Quote - Adds a reply link below each post to easily quote the answered message.
- TipMaster - Show/Hide Spoiler - Adds links to show/hide spoiler tag's content.
- TipMaster - Time Ago - Adds relative approximate equivalent after dates.
These scripts were intentionally kept short. For details see the Greasemonkey section of my site.
