Answer 1

For Google Chrome, you could install one of the following extensions:

1. Regular Expression Searcher

   This extensions allows you to search web pages using regular expression. It uses VI-style keystrokes.

   To start searching, press the slash key ('/'). Enter any JavaScript-valid regular expression and then press enter. All matches will be highlighted in yellow. You can then use 'n' to move to the next match (which will be scrolled into view and highlighted in orange). Pressing 'N' (i.e. shift-n) will move to the previous match. To clear the highlighting, press the slash key again, delete the regular expression, and then press enter.

2. Regular Expression Search
