Ghostery 2.8.1

Bugs: 1056
Cookies/LSOs: 511

New features and bug fixes in 2.8.1
- New panel UI for Ghostery.
- Fixed issue with reappearing toolbar Ghostery icon.
- Click-to-play optimization: inline replacement of common scripts like Twitter Button, Facebook Like, etc.
- Click-to-play purple box and UI box corrected listing.
- Click-to-play now toggles cookies as well as trackers when allowing through click-to-play UI.
- Removed DOM mutation scanning for this release.


Bug fixes in 2.8.0.2
- Fixed an issue where Ghostery would remove extra buttons and other stuff from iframes
- Addressed an intermittent "Unresponsive Scripts" that were triggered when Firefox would wake up from prolonged non-use.


New features and changes in v2.8
- Content policy and dom scanner now comprise a single "true" reporting engine. What that means in practice is that Ghostery will attempt to produce best possible list results by combining what content policy "saw" pass through it and what dom scanner "sees" on any given page. This will also prevent failure of either part (content policy or dom scanner) from completely shutting down Ghostery.
- Tracker priority is now in place, meaning that some of the tracker entries will now have elevated or lowered priority, with vast majority remaining "regular". The priority matters in cases where have generic matching for example: DART or OpenX and the places where a tracker is sub-tracker, for example, any privacy entry.
- Click-to-play overlays have been introduced for Brightcove, Disqus, Intense Debate, and several social buttons
- wizard has been modified slightly: now with arrows
- options/wizard have indeterminate boxes for categories that are partly selected
- Ghosty on the nav bar now behaves like Chrome release: if for any reason, the page is "unblocked" it will be gray instead of blue
- Miscellaneous bug fixes

Total trackers in Ghostery v2.5.3: 518, total protected domain cookies (LSO): 345

Bug fixes in v2.5.3
- Added Firefox 4 customized button that could be dragged into any of the available toolbars.
- Fixed opening Ghostery Options page from Addon Manager.
- The number counts in all places (toolbar, options page, and update pages) is now based on the same number -- number of tracked applications.
- Applied same auto-update behavior to cookie lists as the bug lists -- if everything is selected for blocking, all new cookies will be blocked as well.
- Added upgrade migration script for 2.4+ upgrade to 2.5.3.
- Uninstall of Ghostery will now remove Ghostery folder artifacts from profile directory (unless user.db file had data).

Bug fixes in v2.5.2
- Blocking layer is now optimized to use simple string matching instead of regex when possible resulting in a faster blocking operation. This resolves issues with script not responding on larger pages.
- Re-introduced the Performance Options. While everything is on by default, user has ability to turn some of the more advanced features off speeding up Ghostery.
- Upgrade script from 2.4 branch to v2.5 for selected trackers.
- UI updates.

Bug fixes in v2.5.1
- Translation layer added in Ghostery v2.5 has caused some visual errors in the new options and blocking pages. This issue has been solved.

New features and changes in v2.5
- Added cookie protection that looks for cookie transactions (add & edit) and then compares it to the LSO domain list. If a protected LSO is encountered, Ghostery will deny any change and remove the cookie. This is added through a new "experimental" cookie protection checkbox in Ghostery Options. Denied cookies are listed in the block log.
- Options and blocking pages have been updated to use HTML instead of Firefox UI components (XUL) -- this gives us a more consistent look and feel across Firefox, Safari and Chrome. Additionally, this resolves the issue with displays being too small to see Save and Cancel buttons in Options.
- Added redirection tracking and blocking. This resolves some of the trackers from slipping in when a page issues a 3XX redirect.
- Added support for examining Flash (and other) sub-object requests. This allows the requests blocked but not found in DOM to be correctly reported.
- Whitelisting has been improved to include any potential frames of a whitelisted parent site. Relaxed whitelisting to be less strict: for example, whitelisting ghostery.com will be applied to www.ghostery.com and apps.ghostery.com.
- Groundwork is laid in for user created/maintained tracker lists. This functionality is included in v2.5 branch, tho the UI hasn't been implemented yet.

- Private-browsing mode update - the blocking log and GhostRank are now disabled if Firefox is in private browsing mode;

Improvements and bug fixes in v2.3.1:

Version 2.2.1 87.0 KB Works with Firefox 3.0 - 4.0b6pre, SeaMonkey 2.0a - 2.1b1

Total trackers in Ghostery v2.2.1: 249

New Features in v2.2:
- Web site whitelisting - gives a domain a free pass to let trackers run in cases where you trust the publisher, want to support their research, or have concerns about Ghostery affecting functionality;
- The Block Log - if you've got blocking enabled, Ghostery may actually be busier than you think - it's occasionally difficult to report back into the friendly purple box all of the scripts that Ghostery kept from running. The "block log" keeps a record of everything Ghostery blocks (across all the tabs you have open) so you can check out Ghostery's activity in all of its busybody glory. It's available in the Tools -> Ghostery menu;
- Performance options panel with GhosteryLite mode - turns off some detection and extra goodies in favor of performance. You won't notice or block as many trackers, but for users looking for ultra-quick performance will see a 15% faster Ghostery over full featured mode (a full 23% faster over previous versions);
- Tab switching is now disconnected from page scanning;
- Look and Feel option panel - allows for purple alert to be re-positioned;
- Fixed a couple of detection scripts to eliminate some troublesome false positives (blocking Facebook Connect no longer keeps Facebook from operating, etc);

Improvements and bug fixes in v2.2.1:
- adding ability to whitelist local files per http://getsatisfaction.com/ghostery/topics/cant_add_a_file_url_to_the_whitelist
- Ghostery reporting now supports recognizing frame in frame web-bugs
- added support for Firefox 4 betas
- added support for SeaMonkey 2.0 and 2.1


Note on whitelisting:
Adding sample-site.com to the whitelist will not automatically make sub-domains of sample-site.com whitelisted. So, if you have added sample-site.com to whitelist, but you are browsing www.sample-site.com, Ghostery will assume that www.sample-site.com is not in the whitelist and will execute on the site until you add www.sample-site.com to the whitelist as well.

- really removed the need for Firefox restart when (un)blocking a tracker or any other option updates;
- igoogle and facebook reporting and loading should finally be resolved;
- tab switching and general browsing UI reporting is now fixed: you should only see bugs for that page and not any others;
- img scanning and blocking from the same domain is now ignored;

Note on whitelisting:
Adding sample-site.com to the whitelist will not automatically make sub-domains of sample-site.com whitelisted. So, if you have added sample-site.com to whitelist, but you are browsing www.sample-site.com, Ghostery will assume that www.sample-site.com is not in the whitelist and will execute on the site until you add www.sample-site.com to the whitelist as well.
