We all are regular user of google chat service. To use this service either we use the stand-alone G- Talk desktop client or the floating AJAX version in Gmail. But i feel that Google Talk Gadget is more usable than both of them. Here, each chat session opens up as a tab (like tabs are open in Firefox browser). It can show previews of images or video and the chat client can easily be embedded inside WebPages.
Problem With It: The webpage (like the Google personalized page) where we have embedded the G-Talk gadget must be in front of us all the time.
Solution: Put the Google Talk client in the Firefox sidebar so it always stays in the foreground no matter what website you are on currently.
To add Google Talk to your Firefox sidebar follow these steps.
1. Bookmark the following URL http://talkgadget.google.com/talkgadget/client
2. Now goto Bookmarks menu, navigate to the above bookmark, right click on it and choose Properties. click the checkbox that says “Load this bookmark in the sidebar“.
3. Now go to View->Sidebar->Bookmarks and click on this bookmark. You are done now.
Most of the corporate offices, colleges block gtalk along with other messengers. With this trick, you’ll be able to access google talk, MSN, Yahoo and ICQ messengers in the offices, schools or any other places where these messengers are blocked for use.
Or you can try Yoono addon in firefox or chrome..does d same in FF atleast..plus it supports not jus Gtalk but other social N/w sites too
Thanx buddy for this info
