QRZ.com and QRZ.ru are the most comprehensive online amateur radio callsign databases on the web. With the help of the Mozilla plugin ConQuery (by Vasa Maximov), it is possible to look up callsigns which appear on websites, in eMails or Usenet-articles displayed by Mozilla, Firefox and Thunderbird in the online databases.
All you need to do is install ConQuery and add qrz.cqr (qrz.com) and/or qrzru.cqr (qrz.ru) to the "searchplugins" subdirectory of your Mozilla/Firefox/Thunderbird folder.
Then restart Firefox/Thunderbird/Mozilla, that's it!
Highlight a callsign, right-click to open the context-menu, chose "Query to... -> QRZ.com/QRZ.ru". A new browser-tab with the QRZ profile of the highlighted callsign will open.
Portable indicators etc. are automatically stripped off. In the screenshot below, EA9/G3SXW is highlighted, but only G3SXW is queried to QRZ.com.
All projects are also available via Subversion.
For those not familiar with SVN: You can always fetch the latest version by:
svn checkout svn://dl0tud.tu-dresden.de/yfk/ # whole repository
svn checkout svn://dl0tud.tu-dresden.de/yfk/qrq/ # only qrq
svn checkout svn://dl0tud.tu-dresden.de/yfk/yfklog/ # only yfklog etc...
But be aware that this version may not be 'stable' at all. If you don't like experiments, just continue to use the normal releases.
I'll gladly grant write access to the repository as needed, just drop me a line.
