Pop-up advertising impacts most users' Web browsing experience. GlimmerBlocker for Mac blocks most advertisements adequately, all while stopping the need for reinstallation after browser updates.

Download of GlimmerBlocker for Mac completed quickly and the program installed as a separate application modified from the main computer preferences menu. Unlike other third-party ad blocking applications, this program is outside of the Web browser, itself, which prevents it from being deleted or modified when the browser updates. The application has no menu of its own during operations and works in the background to prevent animated ads from playing. Support for product updates is available and the application automatically checks for them at certain time intervals. The program's settings menu has a number of useful options, which allow the user to view blocking reports, add additional filtering, and track suspected Web pages. During our tests while web browsing, the program appeared to block relevant ads, and the history forms showed the different Web services that were blocked. While the program worked well, some of the advanced features would have been more useful with user instructions included.

For those who need a pop-up ad blocker that works outside a Web browser, GlimmerBlocker for Mac performs well, although average Mac users may not be able to take advantage of its advanced features.

What's new in version 1.4.7

Bug fixes and better compatibility Workaround for invalid http response headers sent from some of the Akamai servers which Apple uses for their site. This made the Apple site hang for some requests. Reported by Daniel Greve Rose et.al. Opening the System Preferences Panel is now faster when you have filters with a huge number of rules. Accept "200 OK" in addition to "204 No content" and "201 Created" when publishing an filter using WebDav. Reported by Cornelius Wilkening. Does't add the keyword filter by default as Safari 5 doesn't work well with keywords due to address-bar history search. "application/javascript" is added to the mime-types which is considered javascripts (had application/x-javascript and text/javascript and text/ecmascript)

    Developer's Description

    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 makes it much 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. See the included filters for examples, e.g. adding a download link to YouTube.
