Disable all add-ons in both browsers and then compare. 

Or, you could use a browser that is reliable, well supported, sans bells, whistles and next to worthless problem creating extensions and add-ons. One that doesn't see a version change every week if not sooner and works and behaves like it should. Maybe you've heard of it...Internet Explorer. I prefer #9, but even the #8 variety gets the job done. I'm not  going to say anything bad about #10 but it is a work in progress at the moment and comes in a questionable wrapper.

I have the same problems even with add-ons disabled. 

I've been an avid hater of Firefox for years now. Every single system I ever used it on had a problem with memory leaks and slowdowns. Did I use addons? Of course I did, that is WHY I used it, because it had some cool addons.

For quite some time now I've been using Chrome with Speed Dial 2, Adblock Plus, Roboform, and Photo Zoom for Facebook.

Is it faster than IE10 ? Dunno, but you can bet your ass it is faster and much more reliable than firefox ever was on it's best days.

Sorry. I can't use IE. It just doesn't behave like I need it to. It's not fast, has no add ons that I need like ad blocking. 

Chrome doesn't work properly with Sharepoint sites and Silverlight crashes all the time in it... and IE freezes if you blink at it (no joke--even on a brand new install of Windows in a VM recently, it froze on first run). On the other hand, Firefox actually works... so I can *do* work.

Firefox.

The real animal...

Use what you like, works for you and has the features you need. You want adblock, I want WB's to skin it. FF has always been my last choice as a browser, but I do use Chrome portable from time to time.

IE10 did something disastrous to FSX....and that makes sense because both are MS proggies....

...so I use IE9 ....and the only issue with that is Canon Webprint doesn't work in it for 7-64bit ...so I can't print from the browser....for that I use Chrome...

let me use up some of my saved-up troll cookies with this reply......hehe 

IE 10 all the way!   It is the fastest [functioning] browser I've used to date.  

Then again in my experience IE has always been fast (program load and browse times) and add to that the small memory footprint of IE and you've got all 'wins' in my book.......

@Jafo   What did IE 10 do to FSX if I may ask (and it's not too off topic...)

EDIT:

If I had to choose one or the other, (Chrome or Firefox) it would be Chrome..........

Has anyone seen Starkers lately? Had a question for him. 

he hasn't been around

I can't stand IE, as a web developer IE is the most annoying thing i have to consider every time i sit down to write some javascript or css for a site. It doesn't follow hardly any standards. It is getting better with that but it's still a pain point. If the company would allow me i'd make it so that anybody viewing the page in IE would get a completely different page... one showing the outrageous disregard for web standards and how much better the web would be if people didn't use IE at all. I mean people who are using IE don't even understand the functionality that they're missing because IE doesn't support it. So they never get it to see it in the first place, and even if you did it's because some poor developer had to slave to get it working in IE when it probably took a tenth of the time getting it to work in every other browser used on the web. So the 90/10 rule applies here. It takes 10% of the time getting it to work for 90% of the browser and 90% of the time getting it to work in IE.

But to all there own, If IE is your browser of choice then more power to you. It is unfortunately one that most business's force on there employees more then any other browser. which is a shame really

I've been told that IE10 is the first fully standards-based browser from MS and that it is highly secure.  Recommended by our tech support guy (who hates most things MS despite making a good living thanks to their ineptness) as the default for all our Win7 (business) machines.  For all other OS flavors (XP) he advises Chrome (based on its security).

Being a tweaker, I prefer to use Palemoon on my personal rigs.

never heard of palemoon, will have to try that one out.
