gnome-terminalgooglesearch
I want to have an option like Search on Google available in selected text's context menu in gnome-terminal. Something similar to the option which is available in selected text's context menu in google chrome / chromium / firefox browser:
So, something similar like in the above image, but in gnome-terminal. Is this possible?
I believe I have it nailed down.
Google uses items from your past searches to narrow your searches results.
The highlighted link to "Web History" (available when you are connected to Google) lets you know what kind of history information Google uses to narrow your searches down. (It can be a lot of things, but default settings only look at your past Google Searches) 
After a visit to that link, a nuking of the "Web History information", and some wait time for Google to flush results from its system, results became consistent between incognito and normal mode in Chromium.
I believe that Web History is used only for people who visit Google Search while connected to a Google account. (Which will be your default state if you are a Google account user.)
After some more verification, I have confirmed that Web History is also activated by default for people who do not have a Google account (I suspect it works with a cookie). Though one cannot see what kind of information Google has without a Google account, there is a link to choose to opt-out.
NB: I believe that the only other big factor in Google's results is the chosen search language (obvious when you think about it, but it kind of bugged me before I saw that Chromium was set in English and Chrome in French).
For 12.10–15.04 you can create a CSS theme for GTK 3.0 as explained in this comment by Kees (kees-vanveen) on the bug report posted above by Alessio.
Create the file ~/.config/gtk-3.0/gtk.css
Paste this as the contents using your desired color:
TerminalWindow .notebook tab:active {
background-color: #def;
}
Close all Terminal windows and relaunch the application to see the change.

Yes, there is an option. First download the following deb packages:
the data package: gnome-terminal-data_3.6.1_all.deb
the main package: gnome-terminal_i386.deb (for 32-bit OS) or gnome-terminal_amd64.deb(for 64-bit OS)
Second, install them using the following commands in your terminal:
And third, restart your terminal.
From now, when you will open your gnome-terminal you can quickly search on Google command line errors, warnings and other things. Highlight the text, right-click on it and choose "Search on Google". It opens the default web browser and go to the google search result page:
