Firefox 4.0 beta 3 released

[Not Myself]

can i run mozilla 3.6.8 & mozilla 4 beta 3 at the same time ?

To do this, you will want to use separate Firefox profiles.

If you're not familiar with profiles:

Profile Manager - MozillaZine Knowledge Base

1. Close Firefox, start the Profile Manager, create a new profile for FF 4.0; give it a recognizable name. Close Profile Manager.

2. Download and install beta, but do not start it. Create a shortcut to it, that should look similar to this:

"C:\Program Files\Mozilla Firefox 4.0 Beta 2\firefox.exe" -p "Beta4" -no-remote

Translation: This link will start 4.0, using its own profile, which I, in my usual fit of total brilliancy, named "Beta4"; that is the `p "Beta4" part of the link.

The `no-remote' part allows you to run both 3.6.x and Beta 4 at the same time.

I'm not going to go into a discussion of the risks of using beta releases, nor the fact that very few FF extensions currently work with Beta 3 (in fact, a few that worked with Beta were disabled in Beta 3; such matters are not germane to your question.

Anyone else getting heavy disk activity for 10-20 seconds upon opening beta 3?

My disk activity stays at 2-8% with B3 open
It might be your AV

I'm using MSE Beta. I'll have to look into it further. Sometimes goes for up to 30 seconds. HD running full bore.

After getting my plumbing done, I checked my add-ons. Beef Taco 1.3.0 add-on was the culprit.

I been a big fan of fire fox for a long time! SO far this new version of fire fox is working perfectly!

I love the new beta, but I can't wait for Beta 5 when the whole Mozilla 2 thing gets implemented! It's going to be awesome! Hopefully... *remembers Firefox 3.5 claims*

Can anyone tell me if Beta 3 still treats tabs like separate instances of Firefox in the Win 7 taskbar? I haven't had a chance to D/L it myself (waiting on certain addons).

Yes it does.

Yes it does.

I was afraid of that. Does anyone else find that terribly inconvenient?

 

[Guntmeister]

I do as a matter of fact. I liked it better with a single instance in the taskbar.

I will not test it till noscript works with it.

New Firefox beta tweaks JavaScript, gains multitouch

Support for multitouch on Windows 7 computers and cross-platform improvements to how the browser handles JavaScript were the biggest changes brought by Mozilla to the third beta of Firefox 4, released Wednesday. Available for Windows, Mac, and Linux, Firefox 4 beta 3 doesn't make any changes to the interface but does make some important adjustments to how the browser handles JavaScript, an essential component of modern browsers.
