Mozilla bất ngờ tung ra Firefox 4.0 RC2

admin Mar 18, 2011 92





Trước thời điểm phiên bản chính thức sẽ trình làng vào ngày 22/3 tới đây, Mozilla lại bất ngờ tung ra bản RC thứ 2 của Firefox 4.0.

Mozilla cho biết Firefox 4.0 bản chính thức vẫn sẽ được ra mắt vào ngày 22/3 như QuantriMang đã đưa tin.

Phiên bản RC2 này được giới công nghệ đánh giá sẽ là phiên bản chính thức (nghĩa là không có gì khác biệt được thay đổi nữa), khắc phục đầy đủ các lỗi phát hiện được trên phiên bản RC1 được ra mắt gần đây.

Đặc biệt, Firefox 4.0 RC2 đã có cải tiến khá tốt về khả năng quản lý bộ nhớ RAM tiêu phụ. Trong trường hợp bạn khôi phục lại hàng loạt tab đã bị đóng trước đó, chỉ những tab nào được người dùng truy cập vào thì nội dung mới bắt đầu được load, nếu không sẽ ở trạng thái chờ.

Điều này đảm bảo rằng dung lượng RAM phải tiêu thụ cho các tab chưa cần sử dụng sẽ không bị tiêu tốn lãng phí. Tính năng này khá giống với tính năng của add-on BarTab.


Những tab nào được người dùng truy cập mới bắt đầu hiển thị nội dung

Trong quá trình thử nghiệm, dung lượng RAM tiêu thụ trên Firefox 4.0 RC2 cũng ít hơn so với trên RC1 và các phiên bản Beta trước đây.

Đây được xem là hành động an toàn của Mozilla trước khi Firefox 4.0 chính thức phát hành, để không làm những ai yêu thích Firefox phải thất vọng vì thời gian chờ đợi quá lâu về những lỗi có thể phát sinh trên phiên bản mới.

Download Firefox 4.0 RC2 miễn phí tại đây.

Kết quả thử nghiệm khả năng xử lý HTML5: Firefox 4.0 RC2 đạt 250/400 điểm (bạn có thể tự tiến hành thử nghiệm tại http://html5test.com/).

Kết quả thử nghiệm AcidTest 3 – Kiểm tra toàn diện trình duyệt: Firefox 4.0 RC2 đạt 97/100 (bạn có thể tự tiến hành kiểm tra tại http://acid3.acidtests.org/).

Kết quả kiểm tra khả năng xử lý JavaScript: Firefox 4.0RC đạt 361,2ms (bạn có thể tự tiến hành kiểm tra tại http://www.webkit.org/perf/sunspider/sunspider.html).

Những ai yêu thích đang hy vọng phiên bản chính thức của Firefox 4.0 sẽ cho những kết quả thử nghiệm tốt hơn và khắc phục hoàn toàn tình trạng “ngốn RAM” đã có từ lâu trên các phiên bản trước đây của Firefox.

    I’ll gear this review to 2 types of people: current Zune owners who are considering an upgrade, and people trying to decide between a Zune and an iPod. (There are other players worth considering out there, like the Sony Walkman X, but I hope this gives you enough info to make an informed decision of the Zune vs players other than the iPod line as well.)

    Apple now has Rhapsody as an app, which is a great start, but it is currently hampered by the inability to store locally on your iPod, and has a dismal 64kbps bit rate. If this changes, then it will somewhat negate this advantage for the Zune, but the 10 songs per month will still be a big plus in Zune Pass’ favor.

Many thanks for the whole lot!

    Thanks for your writing. I would love to say that a health insurance brokerage service also works best for the benefit of the actual coordinators of the group insurance cover. The health insurance broker is given a directory of benefits looked for by someone or a group coordinator. Exactly what a broker really does is hunt for individuals or coordinators which usually best go with those desires. Then he reveals his ideas and if the two of you agree, the broker formulates a contract between the 2 parties.

    Between me and my husband we’ve owned more MP3 players over the years than I can count, including Sansas, iRivers, iPods (classic & touch), the Ibiza Rhapsody, etc. But, the last few years I’ve settled down to one line of players. Why? Because I was happy to discover how well-designed and fun to use the underappreciated (and widely mocked) Zunes are.
