If a habrachelopek for some reason (corporate policy) has to use the hated Internet Explorer 7 browser at work, then he has two choices: either change jobs or make the working browser as similar as possible to the Fire Fox. The second is feasible with several extensions.
IE7Pro - many of the features from popular Firefox extensions, including crash recovery, ad filter, mouse commands, user-agent changes, etc.
Inline search - full-text search over the page in the character set process (unlike Firefox, it works after Ctrl + F).
ieSpell - grammar checker (unlike Firefox, you need to click a button to see errors).

Feed Folder is an analogue of Live Bookmarks in FF.
Developer toolbar - viewing DOM elements on a web page, detecting and structuring objects in code.
