A browser toolbar is a toolbar that resides within a browser's window. All major web browsers provide support to browser toolbar development as a way to extend the browser's GUI and functionality. Browser toolbars are considered to be a particular kind of browser extensions that present a toolbar. Browser toolbars are specific to each browser, which means that a toolbar working on a browser does not work on another one. All browser toolbars must be installed in the corresponding browser before they can be used, and require updates when new versions are released.
Many high profile browser toolbars released over the years have been fraught with issues, either intentionally as malware or injected with computer viruses or due to poor or conflicting programming when considering multiple toolbars being included on the single browser.
Over the 2000s, there was a proliferation of browser add-ons produced and released by a variety of software companies, both large and small, which were designed to extend the browsing experience for the end user. Due to this popularity, and the ease with which users could have these installed, there was additionally an adoption by malware, trojan horse and virus creators to use this as a platform from which they could corrupt or steal information from the users computer. In response to these issues arising, the popularity has since been quelled, with people resorting to alternative means to improve their browsing experience, and seeking crowd sourced advice regarding which browser extensions are appropriate to adopt.
Developing a toolbar
The programming language and development tools behind a browser toolbar vary from one browser to another.
In Internet Explorer 5 or later toolbars may be created as browser extensions written in C# or C++. More specifically, it is possible to create up to three different kinds of toolbars (custom explorer bars, tool bands and desk bands) and to combine them with browser helper objects in order to provide added functionality.
In Firefox, Chrome, Safari and Opera toolbar styling is done though CSS.
Native vs. injected toolbars
Some major browsers (Internet Explorer and Firefox) enable the creation of native toolbars i.e., toolbars which are directly inserted in the browser window. Examples of native toolbars are Google Toolbar and Stumbleupon Toolbar. Native toolbars use browser-specific code to create the same toolbar for each different browser version.
Each approach has advantages and disadvantages for the different stakeholders.
From the user's perspective:
- Native toolbars present faster load times, since injected toolbars must wait for the DOM to be created in order to insert the toolbar in it.
From the developer's perspective:
From the toolbar owner's perspective:
Cross-browser toolbar development
Another way to simplify the task of developing a toolbar for different browsers is to rely on a cross-browser extension development framework. Some of the most important frameworks are listed below:
- Toolbar Studio supports IE, Firefox. This is an IDE that allows to develop toolbars via a visual editor.
- Kynetx supports IE, Firefox, Safari, and Chrome, but extensions are dependent on the Kynetx extension to work. In addition, Kynetx apps are built using a proprietary Kynetx Rules Language. There is no cost to use the Kynetx platform.
- KangoExtensions supports IE, Firefox, Chrome, Safari and Opera. Kango is only free for open source non-profitable projects.
- Conduit supports IE, Firefox, Safari, and Chrome. It enables you creating a branded, customized toolbar that offers users a direct interface or “Conduit” to the most valuable and important segments and links of your Blog or website. Conduit is free, easy to use and allows you to monetize your toolbar with a shared-profit revenue model. Since Conduit basically lets you link from a toolbar a portion of your web page, it inherently lacks from the flexibility of other cross-browser extension development frameworks.
- Widdit's toolbar supports IE, Firefox, Safari, and Chrome. The Widdit platform allows publishers to create a free, customized branded toolbar using a drag and drop online wizard. Through the admin, publishers can add or remove applications and features in real time, and share the toolbar with different communities.
Removing a browser toolbar
Some toolbar providers do not give detailed instructions on how to remove their toolbars. Many 2nd tier providers and software bundled browser toolbars can be difficult to remove without a 3rd party toolbar removal utility.
