As of today Firefox 4 without any doubt is a worthy competitor to other modern browsers. Nevertheless, Mozilla, it seems, is still trying to catch-up with its competitors. Website ConceivablyTech has given the indications that Firefox 5, which is scheduled to be launched on June 21, will implement a number of features that have already been incorporated in Chrome and Internet Explorer 9.
Among the features taken from Chrome include a dedicated new Tab page, multi-select tab, and integrated PDF viewer. It is also reported that Firefox 5 will support web-based add-ons on the taskbar that looks like a feature taken from IE9. It is also assumed that the next Mozilla browser will inform the user about how add-ons and extensions slow down your web browser. A similar function exists in IE9.
But, of course, Firefox 5 would not only “catch up”. It is reported that Mozilla is going to make a number of changes and additions to the original browser: user interface is being optimized, an indicator of file downloads will be added, a permanent tab of home applications will be added, improve the management of various accounts(Identity Management), implement better integration with social networks, allowing users to share links with friends (e.g. , on Facebook or StumbleUpon) directly from the browser.
All this sounds very ambitious, especially given the fact that they have just 3-month period for developing Firefox 5, as the work on version 4 took more than a year. Even Google, which releases new versions of Chrome like hot cakes, usually takes long enough to integrate significant new features.
