I tried using the Japanese version of Firefox Beta 2

Although Internet Explorer is currently being pursued browser "Firefox", beta 2 of the next "version 2" has come out.

The height of the button is slightly lower, the amount of visible page is slightly increased, the RSS part is changed, which tab is active, it is easier to see, it has the function to restore the closed tab And various additional functions and improvements are made.

So, I overwrote it and tried using it.
Download it here.

Mozilla Firefox - Next Generation Browser - Beta Downloads

Launch the installer after downloading

Click "Next"

Please check "I agree to the license agreement" and click "Next"

Select "Standard installation" and click "Next"

Installing

Click "Finish" to quit and start up as it is

Click "Confirm Now" to check compatibility for already installed add-ons

"SEO For Firefox"Seems to correspond to Beta 2 so click" Install now "

Click "Done"

This is a new design of Firefox

By the way this is the old design

The tabs are different, making it easier to see which tabs are active

This is the old version. It may be confusing if it is told indeed.

Even if you want to restore the closed tab once, right click and you will return immediately if you select "Restore closed tab"

RSS also looked like this

RSS reader service on the web is also available

Add - on management (management of extended functions) It has changed a little bit

Other changes are as follows.

Mozilla Developer News >> Blog Archive >> Firefox 2 Beta 2 milestone released

It seems that it corresponded also to JavaScript 1.7, but I do not understand well.

New in JavaScript 1.7 - MDC
