Ever wish you could do a regular expression search on the text of a webpage? FindRegex adds the ability to do this to Internet Explorer. After installing it (click here to download), you can do a regular expression search by right clicking on any web page and choosing "Find Regex".
This has only been tested in Internet Explorer 7+.
NOTE: Ignore the "this can harm your computer" warning on the download page. SkyDrive does that for any file ending in .msi.
