DMs page opens on the oldest tweet

[Rick1212]

Had this since 2.5.4 with FF 36 so I can't say if it's related to echofon or FF.
When you receive a DM and click on the sender, the chrome page opens on the oldest tweet instead of the most recent one.

While I'm at it: said page is pretty annoyng since many functions aren't available:

• Can't select text
• Can't copy a tweet
• Page up / Page down / Hom / End keys don't work
  Could it be possible to remove said limitations?
  Right now the only available oprion is to right click to delete a DM.
