+ Settings are clear and easy to modify.
- something needs to be done for the amout of tabs that a single command line opens. lets say I translate 5 words in a row a 5 engines, thats 25 tabs opened just like that. There is an addon Translation Comparison that has the multi-column view, so, in total youd have one window/popup but several search engines. or any other simpler trick might do as well.

Works great, but keeps focus after pressing ⏎. What can I do about it? It's rather annoying in web apps, which use keyboard shortcuts, because I have to type ⇥ and then the shortcut.

Thanks a lot of this addon.. Have been dying for this one to be present in firefox to move away from chrome. I have around 50-60 such custom search urls and this is a saviour!!

Like everybody says, hate typing ms everytime. Is it possible to customize these 2 chars also? Is it possible to reduce it to one letter and/or allow it to be customizable?

Update: https://superuser.com/a/7374/364519 - Found that all you need to do to have similar custom search urls for firefox, is to create bookmarks with %s in the place - just like in chrome!!! Would be great if this is called out in the addon, as i have been longing for the same to switch to firefox.
