Firefox 4 – Updates, Roadmaps And Changes So Far

Developers and users alike are pretty interested these days in knowing what the Mozilla developers are up to with the new Firefox 4 browser. A product roadmap was released by the foundation giving information on when to expect the next big thing: Firefox 4.
The report details that Firefox 4.0 is due to arrive in either October or November of 2010 and will bring with it a range of new features, such as a new slick user interface and multi-touch gesture support. But take note that this report is currently classed as a ‘draft’ and could be open to any number of changes.

For those existing Firefox users, a plentiful number of changes can be expected prior to the late 2010 release date of 4.0, with both 3.6 and 3.7 lined up for debut before then. These new releases will offer such improvements and features as faster javascript handling, improved form completion tools, bookmark synchronization and pageload enhancements.


Here is a detailed list of the improvements from the foundation’s web site

The new Firefox 4 is going to get animated, as a couple of videos show how browser tabs might work in that version of the popular web browser. The videos highlight something that’s a bit tricky to show in pictures: animations.

One video depicts how Firefox might look when you’re rearranging browser tabs in the future. The other shows what it will look like when you create a new tab. In a nutshell, it looks like Firefox 4.0’s tabs might behave exactly like those in Google Chrome.

In Firefox 3.6, when you click a tab and drag it you see sort of a shadow of the web page you’re currently viewing. You can drag it to the position on the tab bar where you want to drop it, and the tab bar will snap into place. Chrome and Firefox 4 feature smoother transitions.

When you create a new tab it doesn’t just pop up out of nowhere, but rather slides from right to left (see the image above for a rough idea of what this looks like). When you drag a tab from one place in the tab bar to another, all the open tabs will slide around to make room for the repositioned tab.

One area where the Firefox 4 concept has a leg up on Google Chrome is in tab tearing. When you click a tab and drag it out of the tab bar in both programs you can create a new browser window containing just the web page that was open in that tab. In Chrome, this process is a bit jumpy. When you tear off a tab, there’s no real animation. You just have a thumbnail of the web page and when you lift your mouse button the browser window snaps into place.

In the Firefox concept video, when you tear the tab from the first menu, there’s a quick animation. And then when you lift your mouse button the windows gradually (but quickly) zooms from thumbnail size to full size.

Mozilla 4 Wiki Page has released Mock Ups, which would probably be some what similar to Firefox 4. As you can see from the screen shots below, two main versions of the interface is developed. The one interface is having the Browser Window Tasks below the address bar and the other one is the vice versa.

With Mozilla releasing changes to Firefox 3.7 last week, these screen shots reveal more as they give a clear picture on what they are trying to do. Firefox 4 is designed to make the interface much more simpler and intuitive. Increasing Web Page space is another issue that Firefox will look after in its version 4. Also there are a few talks that Firefox 4 would a same Go-Refresh button. It seems that they have done this for the users of IE who want to switch to Firefox.

























Here are the ways experts are hoping Firefox 4 will give users the next generation browsing experience:

Prism

Internet browsers haven’t evolved much from the day IE was first started. The exponentially growing dependency of internet has always conflicted with running desktop apps as an user could never synchronize between the two. These days, you need to open yourbrowser , go to your mailsite and then log into your account to read the mails. What if you had an icon at the desktop clicking on which would have opened a window with your mails only? Or say what if you had google calendars at your desktop?

Prism works right there bridging the two ends into a common platform.

Prism works right there bridging the two ends into a common platform.

Prism is an application that lets users split web applications out of their browser and run them directly on their desktop. A very big part of this initiative is to make sites/apps work when they are not connected to the Internet. HTML 5 (the next version of the basic standard for the encoding of Web sites) includes explicit support for local, offline resources.

Technically, as Mozilla says,

Prism is a simple XULRunner based browser that hosts web applications without the normal web browser user interface. Prism is based on a concept called Site Specific Browsers (SSB). An SSB is an application with an embedded browser designed to work exclusively with a single web application. It doesn’t have the menus, toolbars and accoutrements of a normal web browser. An SSB also has a tighter integration with the OS and desktop than a typical web application running through a web browser.
