Free sharing software software for linux

Search engines like Google do a fine job when it comes to search, but they do little to help us organise our past searches, nor do they make it easy for us to share our search experiences with others. This is more than just an inconvenience because very often we waste time re-searching for results that we know we found earlier. And even more often we find ourselves looking for information that one of our friends or colleagues has already found.

Enhancements:

• Added promotion filters that restrict result promotions in Google to results that have been selected numerous times, that have been tagged, or that have been voted up more times than they have been voted down.
• Added positive/negative promotion filters to stak creation so that users can cause URLs with the specified string to always or never be promoted on Google result pages.
• Result site favicons are used to annotate URLs promoted by positive filters (where available).
• Added timeouts which reset to the private "My Searches" stak after prolonged inactivity, and that expire the use of query terms as default tags and vote terms.
• Voting and page sharing have been added to the activity feed
• Share and remove options are greyed out in the stak menu for staks where this should not be possible (e.g. "My Searches").
• Added "Preview" feature via an icon next to results on the Google result list users can now browse through the result pages without leaving the result list.
• Enabled page sharing and preview features for non logged-in users.
• Improved the formatting of the icons inserted next to results on the Google result page so that they don't "jump" when results are moused-over.

Requirements:

• Mozilla Firefox
