Hides "conversation view" on Twitter while still preserving the ability to click to expand conversation. This works for me on Chrome.

destroy-blue-lines.css

.conversation-module > li:after, .conversation-module > li:before {
  display: none;
}

ol.conversation-module li.conversation-root,
ol.conversation-module li.conversation-ancestor {
  display: none;
}

li.js-has-navigable-stream.open ol.conversation-module li.conversation-root,
li.js-has-navigable-stream.open ol.conversation-module li.conversation-ancestor {
  display: block;
}

Holy smokes! This is amazing! How exactly do you implement this in Chrome, for us laypeople?

@theoreticalgirl Check out Stylish – lets you manage custom stylesheets in Chrome. https://chrome.google.com/webstore/detail/stylish/fjnbnpbmkenffdnngjfgmeleoegfcffe?hl=en

OMG get this gal a medal or something… 

awesome! thanks!

This is now on userstyles.org, as well: http://userstyles.org/styles/92927/disable-blue-lines-on-twitter

@theoreticalgirl Sorry I didn't see your comment earlier! @PhUU is correct, if you install the Stylish extension you should just be able to do a one-click install of this from userstyles.org.

It doesn't seem to do anything in Stylish for Firefox. Thanks for spending time on this, though.

@mildmojo: The classes should be the same for Firefox. Are you sure it's getting applied to the site? Did you use this one or install it via userstyles.org?

@mildmojo: I just installed Firefox and Stylish and it works fine for me when installed from userstyles.org. Maybe you've got another add-on conflicting with it or something?
