What is Your Favorite Browser?
Firefox and Opera share a lot of similarities: they are both free web browsers with modern features like tabbed browsing and a password manager. However, there's a lot of differences between them too. Firefox is open source and extremely customizable: you can make it do almost anything by using 3rd party extensions. Opera on the other hand is proprietary software and has a lot of useful features "out of the box".
This page will help you decide whether Firefox or Opera is a better browser, and why. Read what others have to say and cast your vote in the discussion and poll below. May the best browser win!
Popular and highly customizable open source browser
Firefox is a free web browser managed by Mozilla Corporation. Since it is open source, there are thousands of extensions and themes available from 3rd party developers that can add new features, improve security or change the looks of the application. Firefox features include tabs, spell check, password manager and other things you'd expect to find in a modern browser. It also supports most current web standards.
Firefox is one of the most popular browsers, losing only to Microsoft's Internet Explorer and Google's Chrome in terms of current use worldwide.
Sleek browser with a number of unique features
Opera is a free proprietary web browser developed by Opera Software. Its features include tabbed browsing, page zooming, mouse gestures, a built-in BitTorrent client and more. A number of key features of modern browsers was in fact pioneered by Opera. The browser is extensible via widgets and third party add-ons, although it strictly limits what these plugins can do as a quality assurance measure.
Opera only has a small part of the PC web browser market; however, Opera Mini is one of the most popular browsers used in mobile phones and PDAs.

I love Firefox. The best browser so far.
anonymous on March 07, 2013:
I love Firefox because it is just incredibly professional and stable,convenient while surfing into the world wide, opening all kind of websites without any limitations, and it has that a very simple beautiful look.
Firefox works great with computers with high performances, if you guys have a piece of junk computer, just go with Chrome or Opera, those browsers are just light in using but limited compared to Firefox.
Again, this is my point of view, and so far, I have not found a very advanced great browser that can deal with Firefox period.

Firefox, Opera was trying to take over my PC. It popped up everywhere and would just take over.

I love Opera because of its .mht extension its turbo engine its memory management. Firefox obviously a faster engine but for the memory management of opera it never re-download same image or other things for twice. From this angle it is much more faster then firefox. On the other hand Opera First introduce speed dial (I think) and it is so much helpful for all of us. Downloading videos from youtube Opera plays some horrible roles this is not good. But web designing in both browser is awesome. So both very well known and active then Internet Explorer and also its 9th version. I use both. But I will prefer Opera for its speed on slow connections.

FIrefox is open sourse. And I am in favor of all that we can get. And thus, allows a lot of people to offer things for it.
Its updated fast if there is a problem. And the page rendering is better then Opera.
And importantly, most Security Suites have a plug in for FF, not so with Opera.
velmayilraja on May 02, 2012:
Opera is my choice. Fast and And i like that speed dial in it
anonymous on April 26, 2012:
I hear a lot from others that Opera is faster than Firefox. OK i gave Opera a try, and in my view Firefox is much faster, but it could be just me.
anonymous on March 15, 2012:
@dannystaple: I agree. Little things like that make opera better. Me and you are in the same position
anonymous on March 15, 2012:
Opera is a better browser but a nightmare when it comes to mac downloading. As for safari it is alright. However internet explorer is a useless, slow, virus packed waste of PC space. And chrome may be fast but is very basic and boring
anonymous on March 09, 2012:
i use firefox is the best for downlods and fast,about opera is also good,but i choose firefox,internet explorer 9 is very bad broser

Thanks for this lens!
Iain84 on January 11, 2012:
personally i cannot stand opera. firefox processes websites in the same way as IE but seems to do it more efficiently
anonymous on August 05, 2011:
have been using firefox for about 7yrs and it has been great till now... it struggles with flash videos, it is very slow and buggy. I would go chrome but don't like it either... so I have been using Opera now and until firefox brings back a lightweight edition... OPERA it is.
I even transferred all my bookmarks which means I am dead serious about this haha../
Kirilov on July 27, 2011:
Just take a look at the results from various hacking contest and you will definitely switch from Opera to Firefox. Thanks.
sahilwaste on July 10, 2011:
lovely idea.. i like this lens... very informative... especially links in Browser Market Share for 2011 module... keep it up...
anonymous on April 23, 2011:
I was so disgusted with explorer crashing all the time that I finally switched to firefox. Now it crashes more than explorer ever did. I don't know what to do as explorer will no longer stay open for more than a few minutes on my computer. I have a PC and honestly, if it weren't for work, I'd switch to a MAC tomorrow.

FF > Opera... Chrome > FF
Any browser > IE

@carny: dont be surprised if it over takes within the next 10 years coz now microsoft has to give users the choice :)
anonymous on February 25, 2011:
I used FF for years but it finally became WAY too buggy in 2011 - taking over 60% of my CPU on one simple web page was the last straw but was driving me nuts for months locking up the taskbar and kept failing with ESET NOD32 AV and took so much memory adn didn't release it even when I closed all the tabs down. Good features, way too buggy code.
Moe Wood from Eastern Ontario on December 29, 2010:
I've never used Opera but I've been using Firefox for years and am very resistant to change.
dannystaple on August 17, 2010:
I've been a Firefox user for a long time, but have started to play with Opera, with Unite, Turbo and Link its rather fantastic, although for Squidoo it lacks the tooling from Squidutils and similar.
I've my own Lens on Firefox at http://www.squidoo.com/mozilla-firefox-tips.
Indigo Janson from UK on August 11, 2010:
I like them both. :) Anything but IE!
myraggededge on July 17, 2010:
IE is the pits. I wouldn't even know how to use it nowadays. Firefox is my default but I would refer to use Opera but I depend on such things as Roboform and yes, I know there is a little ap to use it in Opera but it's not nice. Opera by choice, Firefox out of necessity!
Delia on July 09, 2010:
nice informative lens!
anonymous on July 09, 2010:
Nice to see that opera is crushing firefox!
Andrew Po (author) on April 22, 2010:
It's very nice that Firefox is catching up to IE, although it will probably take a while to overtake it :)
