Faster or Lazier Pagination - interesting approach, simply not to determine the amount of sentences, but instead to assume a number of pages and update this when accessing later pages. A bit similar to some websites that only offer a section of the page list as navigation - for this you don't need to know how many pages there really are. Google also cheats by limiting the number of pages to a maximum. For large amounts of data with slow count(*) certainly very useful and possibly you could also combine this with cached maximum page numbers for different queries, so that the next time the assumption about the amount is already more precise.

Please read: Security Issue on AMO « Mozilla Add-ons Blog - it was only a matter of time before the first Firefox extensions with trojans were distributed and slipped through Mozilla's review. Extensions are exactly that - code snippets that run in the same security context as Firefox itself. I believe that in the long run, we need a completely different architecture with much stronger sandboxing for applications and extensions if we want to get this under control.
