Top 4 reasons to not install Firefox 3

June 19th, 2008

1 – It is buggy.

Several improvements, yeah, sure, performance is awesome, the zoom is great, but also several problems. As they – the devs – had a fixed deadline, some things slipped. I got lots of behavior problems with elements with events that are contained in a div style=”display”: none” and shown later. The app became unusable.

2 – No firebug

Enough said.

3 – No JS debugging

I rarely need to use it, but the times that I do need to track a misbehavior, it would be just impossible to do it without a proper debug.

4 – You can’t have FF2 and FF3 on the same machine.

I couldn’t find a way to have both installed, which would be acceptable. I’m sure there’s a way. I just uninstalled FF3, and were able to get FF2 working fine. Any pointers?

You would think that browser developers would make it easy for web programmers / designers to test multiple versions of the browser at the same time :)

Anyways, here is a guide on installing FF2 and FF3 on the same machine…

I haven’t tried this, but was reading it earlier, about how to FF2 and FF3 to run side-by-side:
http://blog.codefront.net/2007/08/20/how-to-have-firefox-3-and-firefox-2-running-at-the-same-time/

Also – there is a version of Firebug working for FF3:

1- I didn’t test it thoroughly, so no pointers.
2- Use de Firebug 1.1 Beta http://getfirebug.com/releases/firebug/1.1/firebug-1.1.0b11.xpi which correctly supports FF3
3- Resolved using Firebug
4- http://blog.codefront.net/2007/08/20/how-to-have-firefox-3-and-firefox-2-running-at-the-same-time/

Good Luck!

Hi Hammet, well, I’m currenlty using FF3 with Firebug 1.20b3 and it’s working awsome (using it for heavy web development).
Also, it is possible to have both, FF2 and FF3 on the same machine, you have to play with profiles and you can only run one at a time. Follow this howto link to get directions http://support.mozilla.com/en-US/kb/Running+different+versions+of+Firefox+at+the+same+time.

@hammet: I’m using this version of firebug with firefox 3.

Ben Tsai Says:

Just a ditto to Ignacio’s comment. I’m running Firebug 1.20b3. I’ve also setup fx2 and fx3 to run on the same machine. It was just a matter of 1) creating a separate profile for firefox 2 and 2) creating a shortcut to run firefox 2 using that other profile. BTW, the above link was broken, so here it is:

Ok, Ignacio beat me here.

Ditto in both accounts, here goes another link to a blog post with details on running both versions:

I haven’t notice the problem you mention with the hidden div’s (one of our main products works exactly like that) but we use Prototype to attach events to elements, so maybe that is helping us?

The issue I had was with some of the extensions installed under FF 2.0 originally after updating they killed FF 3.0 every time I visit some webpages. (This was before discovering the profiles trick)

Disabling them and only installing FF 3.0 extension did the trick. Since them no more crashing.

Colin Ramsay Says:

Surely #2 and #3 are related? Firebug has full javascript debugging.

Regarding #1, everyone has different experiences but I’ve been working with FF3 for months now and not seen any issues like you describe. Either I’m lucky or you’re unlucky!

Andre Loker Says:

I played with FF 3 today and agree that it’s still buggy. E.g., all of a sudden, JS stopped working altogether.

Two things to note:
Firebug is available for FF 3: https://addons.mozilla.org/en-US/firefox/addon/1843
I installed it today. It has some nice new features.
With Firebug available you’ve got a JS debugger at your hands.
Other plug ins that run with FF3 are web developer toolbar, IE tabs, YSlow and adblock plus (which is about all I use on a regular basis)

Regarding FF2 and FF3 side by side: Ignacio’s link does not work, but coincidentally I blogged about this very topic today: http://blog.andreloker.de/post/2008/06/Firefox-2-and-3-side-by-side.aspx
FF2 and FF3 run smoothly side by side on my machine.

I’ll definitively keep using FF2 as my primary browser for quite some time, but looking how stuff works in FF3 is useful, too.

Regards,
Andre

1) FF3 is at least as solid as FF2 for me and it’s memory usage is much better than FF2. JavaScript runs much faster than in previous versions as well.

2) Firebug works great on FF3, it’s a beta, but it’s been solid for me.

3) Firebug has decent JavaScript debugging.

4) I haven’t figured out how to get both installed side by side.

etal Says:

The easiest way to have both FF versions on the same machine is to install one of them from http://portableapps.com.
I’m not sure you can have them both running at the same time though.

alberto Says:

2) I have Firebug 1.1.0b10 installed here

4) I have FF2 & FF3 installed on my (linux) machine, so they can certainly be installed at the same time.

I played with FF 3 today and agree that it’s still buggy. E.g., all of a sudden, JS stopped working altogether.

Other plug ins (besides Firebug) that already run with FF3 are web developer toolbar, IE tabs, YSlow and adblock plus (which is about all I use on a regular basis), so add-in wise it’s not so bad.

Kevin Says:

1) I’ve had no bugs, it seems to work great.
2) I’ve got Firebug 1.2 beta, and it works fine.
3) see #2
4) install in a different folder, and set up separate profiles. It works just fine.

Victor Kornov Says:

Interesting, how people post not reading other comments. That’s all I have to say after reading what other people have written :)

Steve Gentile Says:

I’m having a problem with jQuery ajax and FF3

Been fighting it all day today.

Unfortunately so, as I’m an avid Firefox fan

Danyal Says:

Somebody else noticed this! At work yesterday we joked, would firefox 3 become another browser we had to fix one off bugs for, like IE6? Still, at least we know these bugs will get fixed over time. I’m pretty sure they won’t be releasing FF4 with a quirks mode.

“C:\Programs\Mozilla Firefox3\firefox.exe” -P FF3ProfileName -no-remote

goodwill Says:

Most JS bugs I bet is caused by the new implemented getElementsByClassName natively, as I have came across bugs about this since FF3 beta. And the bad thing is Safari also had such issues since 3.1.1.
