Full Article Attached Mozilla Firefox 3 Released

Tuesday June 17th, 2008

Mozilla Firefox 3 has been released. Available for Windows, Mac OS X and Linux in 46 different localisations, Firefox 3 is the most major Mozilla browser release since the launch of Firefox 2 in October 2006 and represents the culmination of over three years work (development on Firefox 3 began before even Firefox 1.5 came out). According to the press release announcing Firefox 3, the new version has over 15,000 improvements.

Firefox 3 can be downloaded from the redesigned Firefox product page or the Firefox 3.0 directory on (it's not yet being offered to Firefox 2 users via the software update system). More information can be found in the Firefox 3 Release Notes.

The use of newer technologies means that Firefox 3 has higher system requirements than Firefox 2. In Microsoft land, Windows 95, 98, ME and NT 4.0 are no longer supported. On the Mac side, the minimum OS X version jumps from 10.2 Jaguar to 10.4 Tiger. In both cases, the operating system versions that are no longer supported have long since been abandoned by even Microsoft and Apple.

The Mozilla servers have been experiencing problems due to high demand for Firefox 3. This actually delayed the full release of Firefox 3 by more than an hour. According to a Mozilla Developer News weblog post, Firefox 3 is being downloaded more than 14,000 times a minute.

With the launch of Firefox 3, Mozilla is hoping to set a Guinness World Record for the most downloads in twenty-four hours. The number of downloads so far can be tracked at Only full, completed downloads count and users have until 11:16am Pacific Daylight Time on Wednesday (6:16pm UTC/GMT) to make a participating download. The official Mozilla Blog has an entry about the Download Day with more details.

Those who just can't get enough of the Firefox 3 launch are invited to attend a Mozilla Party to celebrate or watch the action live from Mozilla HQ on Air Mozilla.

#1 Server "Problems"

How many other web sites actually "schedule" a Denial-Of-Service outage against themselves? *tee.hee*

I notice betanews and other sites have the file on their websites. Betanews says that they will be counting their downloads to add it to mozillas numbers. Is this true?

#3 Win9x dropped

And yet there is a port of Firefox 3 for OS/2. Go figure.

I fully understand developers have to draw a line somewhere so they don't wind up having to re-implement newer OS features for older ones, but there are still a number of Win98 users out there. At any rate, if anyone is out there is crazy enough to create a "port" back to Win9x, even sans a few features, I would be interested in kicking it around.

#4 How to wreck a good browser... 3.0 released.

by renaljim

Well.... all the hype and not even close to the last build of Mozilla!

Mozilla's release 3.0 is slower.... appears to hog more resources.... and doubtful that the full release is anything more than a release of the RC3.0 version.... just hurried to meet a deadline for a world record for downloads!

I personally followed the Beta thru the RC candidates of 3.0 objectively and installed them as they came out.

Personally in my view, the changes were minimal at best.... disappointing to say the least!

Add ons are minimal.... at least for now... and yes i know that in time, the great developers will create some really neat and USEFUL add ons for 3.0... but, I would wait and see if Mozilla takes the browser back to the drawing board FIRST!

I'll stick with Mozilla, YES! .... but the last version of 2.0 in my machines will stay.... since i've already uninstalled 3.0 just today and reinstalled the last version of 2.0 already this morning!

Sorry guys! Mozilla 3.0 doesn't add up to the hype!

A large number of downloads doesn't mean it's a GREAT browser! It just means that the exposure and marketing techniques are GREAT!

#5 Copying from the address bar

by mhenriday

Wednesday June 18th, 2008 2:08 PM

A rather odd bug that I've noted on my machine, irrespective of platform (64-bit Ubuntu Hardy,32-bit Windows XP or Vista), is that I find myself unable to copy an address from the address bar by highlighting it, right-clicking, and choosing «Copy» from the menu that opens. A copy can, however, be made successfully by using the «Ctrl+C» keyboard shortcut. Once such a copy has been made it can be pasted into, e g, a text editor by the usual methods, i e, either right-clicking and choosing «Paste» or typing «Ctrl+V». Aside from the special situation of the address bar, right-clicking to copy works perfectly well ; I can, for example, copy this text to a text editor by this means without any difficulty at all. Could this odd behaviour on the part of the address bar possibly be related to the «awesome» function ? In any event, while not a deal breaker - I am quite impressed with Firefox 3 and intend to use it or modified versions (Swiftweasel on Ubuntu) as my default brower - it would be nice if the Mozilla developers could patch this minor annoyance as soon as possible....


#6 FF3 hogging more resources?

If that were so, renaljim, then those Firefox memory tweaks I've been using since Firefox 1.x are STILL NEEDED for Firefox 3. The creators of Firefox should have added those tweaks like "browser.cache.memory.capacity" into the about:config dialog box without users having to add them manually.

The makers of Netscape 9.x browsers were smart enough to add such memory tweaks like "browser.cache.memory.capacity" which is why their browsers use less resources and are more stable than Firefox.

And for those who cannot install nor use the AdBlock Plus extension under the final release of Firefox 3, get the latest version here instead of from the AdBlock Plus creator's site:

#7 Copying from the addressbar : resolved

by mhenriday

The cause of this problem I describe above seems to be interference by the latest, FF3-compatible version of Dao Gottwald's «Locationbar». Uninstalling the add-on resolves the problem....


#8 Zoom

ff's zoom feature is "broken". It now behaves like IE7. Zoom was the biggest reason to prefer Firefox over IE, but I can find no way to tell FF3 to act like FF2. Please tell me there is a switch somewhere...

Now I can put FF3 on all my machines!

#12 Closing popups slows the browser

by underscore

Saturday June 28th, 2008 4:12 PM

I've noticed in FF3, when I close a popup window, the browser tends to hang for a couple seconds before the popup actually closes.

I didn't see this in any of the betas.
