The problem with other ad-blockers for Safari is that they are implemented as awful hacks: as an InputManager and/or ApplicationEnhancer. This compromises the stability of Safari and very often create problems when Apple releases a new version of Safari. GlimmerBlocker is implemented as an http proxy, so the stability of Safari isn't compromised because it doesn't use any hacks. It is even compatible with all other browsers. You'll always be able to upgrade Safari without breaking GlimmerBlocker (or waiting for a new release); and you'll be able to upgrade GlimmerBlocker without upgrading Safari. This will make it a lot easier to use the beta versions of Safari and especially the nightly builds of WebKit. Because GlimmerBlocker doesn't hack Safari, there is a few things it isn't able to do: adding a block by right-clicking an image, stopping pop-unders, and filtering cookies from 3rd party sites. But you win a lot in stability, and GlimmerBlocker provides much easier methods for adding your own modifications to pages by adding css rules, pieces of Javascript or by transforming the html before Safari receives it. So I'll hope you're happy with the tradeoff. If you can program in Javascript you'll be able to add your own modification to pages.What's New in This Release: [ read full changelog ]History tab:· New tab med recent blocks, whitelistings and transforms. Shows all the rules that modified a request.Keyword expansion in Safari:· Type "wiki great gatsby" in Safari's URL field to perform a Wikipedia search. New default filter includes a bunch of expansions. Supports both Firefox-style simple URL macro expansions and javascript-based expansions. By suggestion from Karsten Bruns.· This works only in Safari because the other browsers have their own support for keyword expansion.Better error page:· Improved "host not found / doesn't respond / etc" error page with links to Google cache, Coral cache, Wayback, WhoIs and Traceroute. By suggestion from Leo M.Preview when editing rule:· Filter rule edit sheet now has a 'preview' button. This temporary applies the new settings. If you click cancel after 'preview', all changes are reverted (and not just those since you clicked 'preview'). This is how Apple describes the 'Apply' button should work, but I'm afraid too many users are used to the Windows standard which takes 'apply' as "save without closing", i.e. commits the changes forever. Suggestion from Nicolas Berloquin.Other fixes and improvements:· Added Javascript can now be placed just after or or just before or . Suggestion from Karsten Bruns.· Limits time the proxy server internally can cache DNS lookups to 30 seconds and to 10 seconds for failed lookups. This should avoid problems with web-sites that changes ip-address. When update of a subscription fail due to "unknown host", GlimmerBlocker now retries after 1 hour instead of 1 day.· Fixed installer problem which made installation fail if the LaunchDaemons directory did not exist. Thanks to Matthias Ruszala for reporting this bug.· Filter edit "summary text" is now replaced with marker in the tab title. Takes less space and the text became way too complex with the new options.· The CONNECT http proxy now only allows port 443 (https) and 563 (snews) to tighten security.· Improved website compability: does not add charset to content-type header if charset was not specified in the headers sent from the server.· You can now drag (or copy) URLs from the suspects tab and the history tab.· After editing a rule, suspects which matches current rules are removed from the suspect list. Re-suggestion from Karsten Bruns.
