If Google Chrome is your browser of choice, the Send to Instapaper extension is exactly what you're after. Rather than merely replacing a bookmarklet with a browser action button, this extension adds an entry to your context menu. Right-click a link that you'd like to check out later on, and it's added to your queue.
You'll need to be signed in to your Instapaper account first, as the extension doesn't store your username or password.
Have you ever wanted to change the item listed in the context menu in Firefox and find that there are no ways for you to change it in the Preferences section? The Firefox browser comes with a list of preset items for your context menu and is supposed to be the most useful options during browsing. Since we all have different browsing habit, won’t it be great if we can rearrange the items in the context menu and add/remove items to enhance our efficiency?
Firefox does not comes with such option for you to change the context menu, so we have to rely on the menu editor extension to get the thing. With this extension, you can now edit your context menu (and any other menus), rearrange the options, hide the unnecessary and even add entry from other menus.
Install the menu editor addon from here. Alternatively, you can search for it in the Firefox Addon section.
There's a big crop new extensions showing up which take advantage of Google Chrome's new context menu API, and that's great news for those of you who can't live without your right-click menu.
You can see a pair of newer extensions in my screenshot -- and while I'm not certain I'll be using the tab switcher, Copy Short URL is probably here to stay.
Just right-click a link and left-click and a bit.ly or tinyurl shortened link is copied to your clipboard for hassle-free sharing on your favorite social sites. That's it. Nice and simple, just how I like my extensions!
The developer states that more truncators will be added soon, which would be a welcome improvement. API and account support would be a nice touch as well -- perhaps that will be tacked on as well.
