Version: 1.4.1 || Release Date: 2009-09-13 || License: Freeware Developer: Vitality ApS | App Owner: brandon_c

A more stable ad-blocker, allowing Safari upgrades without crashes.

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.

Sorry for my last post. Actually when I upgraded it broke. Reinstalling solves the problem.

It's a shame it doesn't work anymore in 10.7 Lion. Hope a new version comes out.

I used Privoxy (Junkbuster) for years, but was unimpressed at how Mac support for it seemed to be waning with MacPorts being the only way to install recent versions. To be honest I don't particularly want to start resorting to MacPorts, DarwinPorts, Fink, or whatever to install software that then gets squirrelled away in some obscure branch of the filesystem along with a raft of other stuff. I bought a Mac because I got fed up of all the tinkering required on my old Linux box and wanted a computer that "just works". With Snow Leopard I was not looking forward to having to pollute my nice clean system with all that MacPorts junk just for Privoxy, so I was very pleased to find GlimmerBlocker. At last, a proper ad-blocking proxy server written specifically for the Mac, with an interface that makes configuration relatively simple without having to edit numerous files (if you can find them on your filesystem!). The only downside is the time taken to move my Privoxy rules to GlimmerBlocker.

- Adding new rules is not exactly fast. and what I mean by that is it takes several steps. First you have to find out what you wanna block, than you have to launch Gb's prefpane, click a couple of times... Maybe some solution involving applescripts could speed up this process.
- There's no easylist/easylist element/easy privacy equivalents in the current list of default subscriptions. I think fixing this would require some community effort.

+ Replaces any adblocking hack for Safari. And because it supports div blocking you're no longer forced to view huge blank spaces instead of ads.
+ Allows you to use custom css on particular site/domain i.e. from This equals to complete Stylish functionality.
+ Let's you inject scripts. This equals to some of the Greasemonkey functionality. What's also worth mentioning is that this is a much more cleaner and effective solution than Greasescript (simbl based Input Manager plugin).
Youtube HD Suite and Greased Lightbox are 2 scripts I'd recommend. Both are working flawlessly.
+ It's already been said but... quicksearches / keyword searches from url bar is what I always missed in Safari.
+ So far it seems really resource friendly and any lag is unnoticeable.

(Cons in the next comment)

A great program. Using this I was able to dump both SafariBlock and Glims right away as GlimmerBlocker does the main thing that Glims did for me also, which is Safari keyword expansions. The bonus here is that there's no need to wait for new software versions after Safari updates anymore.

Snow Leopard compatible also.

I wonder, does this - as e.g. hankydysplasia says - slow down loading webpages? As the proxy-server is the local computer, this should not be a real issue, right?

Also, I wonder, does it affect the quality of AirTunes?

Many thanks!

love it!

I really like this program. It works great for things like my RSS reader (NetNewsWire) as well as all the browsers.

However, I ultimately had to disable it because there was a noticable slowdown on loading web pages on both my MacBook Pro and Mac Mini.
