How to solve Firefox Hangs (Not Responding) Problem

Firefox not responding proble, firefox hangs, firefox hang up, firefox browser problem nepal

Are you facing firefox browser's constantly lagging and not responding problem? After upgrading to newer version 5.0, i was facing that problem very often. When i try to open new tab, it automatically stops responding and does nothing for more than minute. I thought it's because of hyper threading, i tried to lower that and I have also tried clearing my cache and cookies. The problem was not in my computer, it was only on firefox browser. So i did know there is something wrong in firefox. Then i downgraded it to older version 3.6 but that problem was still there.

IE9 tech preview performs 7.8 times better than IE8

In the first series of comprehensive performance tests comparing Microsoft's Internet Explorer 9 technical preview, released yesterday, to stable Web browsers in current use today, Betanews confirmed superb speed gains by the IE9 chassis in specific categories. Not everything in the new IE9 was faster than IE8, but in the computational department, the development team's Chakra JavaScript engine shows much-needed gains.

The rise of Google Chrome

Google's Chrome accounts only for about 4 percent of browser usage worldwide, but in 2009, it exerted outsized influence.

Google launched the open-source browser in 2008, prompting many to ask why anyone needed another after Microsoft's Internet Explorer, Mozilla's Firefox, and Apple's Safari. But over the course of 2009, Google answered that question: with Chrome, the company wants not just to speed up the Web but to rebuild its foundations.

A grim day for browser security at hacker contest

Internet browser security took a beating during Day 1 of an annual hacking competition, with Apple's Safari, Microsoft's Internet Explorer and Mozilla's Firefox all being felled in a matter of hours.

The uncontested champion of the contest was a University of Oldenburg, master's candidate, who managed to fell Safari, IE 8 and Firefox at the Pwn2Own contest at the CanSecWest security conference in Vancouver, British Columbia. He joined security researcher Charlie Miller, who was able to successfully hack Safari with a separate remote-execution exploit.

"It's not as easy as a few years ago," said Nils, the University of Oldenburg student, referring to the difficulty of piercing the many built-in protections of Safari, IE and Firefox. "Still, browsers have a lot of problems. It's really a lot of codes that are exposed to the internet." The computer science student declined to give his last name.

The Pwn2Own contest has thrived at proving to the world that with the proper financial incentive, virtually any internet-facing software can be proven vulnerable to real-world exploits. Amid the awe that took hold as four exploits materialized before spectators' very eyes was this sad realization: Despite the formidable resources of the world's biggest software organizations, browser users remain susceptible to drive-by attacks that can install keylogging software, rootkits and other software parasites with little or no warning.

Perhaps more remarkable than watching hackers in one room make mince meat of three of the world's most popular browsers was the realization that they were willing to do so for well under the going rate. According to some researchers, a reliably exploitable IE vulnerability now fetches $100,000 on the black market. Yet Nils was willing to accept just $5,000 and a new Sony Vaio for his attack.

The contest is sponsored by security firm TippingPoint, which for several years now has paid a bounty to researchers for exploits that target commonly used programs.

"If this competition hadn't existed, I never would have found this bug," said Miller, who is principal analyst at Independent Security Evaluators, referring to the Safari flaw he exploited this year. He exploited a separate vulnerability last year that allowed him to pwn a brand new Mac Book Air running a fully patched version of Leopard. The challenge was enough to motivate him to dust off a separate Safari bug he had been sitting on for more than 12 months for this year's competition.

"If it wasn't for the competition, there'd still be these two bugs from this year and last year," he added. "Apple gets free bugs, I get money and people's computers get fixed."

New Opera Web browser is speedy and feature-packed

Opera has always been packed with features, but it has yet to garner the same kind of publicity that Internet Explorer, Firefox, and Chrome enjoy. And that's a shame, because version 10 of the venerable Web browser adds a slew of clever features that anyone who surfs the Web will welcome.

Like previous versions, Opera 10 is fast, configurable, and clean-looking--and it offers just about everything you'd expect in a modern browser, including a pop-up blocker, plug-ins, an RSS reader, and an antiphishing tool. Unlike competing browsers, it also has a surprisingly good built-in e-mail client, with support for POP3 and IMAP servers, the ability to create incoming message rules, and a spam filter. And, once again in this version, Opera bristles with features too numerous to mention in this short review, yet it packs them all into an elegant, simple-to-use interface.

The new features don't clutter up the browser or make it more difficult to use. Overall, Opera 10 is sleeker-looking than previous versions. But Opera's added beauty is more than skin-deep. Tab handling, for example, has improved, in that you can now configure the browser so that thumbnails of all of your tabs appear above each tab; the thumbnails are resizable as well.

Another worthy addition is the new Speed Dial feature (pictured above). Speed Dial improves on Safari 4's similar Top Sites feature by virtue of being more configurable. You can customize the page that appears whenever you open a new tab in Opera so that anywhere from 4 to 24 of your favorite Web sites display as thumbnails. That way, you can more quickly get to the sites you visit most often, with a simple click on a thumbnail. The feature is turned on by default, and the settings seem to offer no way to turn it off--not that you'd want to, though, because it has no downside.

Opera has always displayed pages quickly, and the newest version is even speedier, particularly on interactive sites that use a lot of resources, such as Facebook and Gmail. Opera claims a 40 percent increase in speed, but we couldn't verify that.

Among other new features are an inline spelling checker (which will be particularly welcome to bloggers) and Opera Turbo, a compression technology that Opera says will allow you to surf faster on slow connections, such as via dial-up. As a broadband user, I was not able to test this feature, so I can't vouch for it.

Surprisingly, given how many features Opera has, it still lacks one feature that IE, Firefox, and Chrome all have: a privacy mode that makes all traces of your Web-surfing session vanish after you close the browser. If such a feature is important to you, Opera isn't the best choice.

Should you replace your current browser with Opera? Which browser you use is a personal decision, so we can't give a one-size-fits-all answer. But anyone who has ever wished that their browser were faster and more feature-packed will certainly want to give Opera 10 a try.

Designing for IE - Design for Firefox First

Designing Web pages is challenging enough without having to build pages that work on every possible combination of Web browser and operating system in existence. So many Web designers choose to take the easy route and design just for the most popular browser, which is IE 6 right now.

But if you're going to focus your site on IE 6 you'll be causing some problems for yourself:

* When IE 7 comes out, your site will need to be redesigned.
* People who use other browsers won't get a good experience.
* If new browsers come out and gain popularity, chances are your site won't be able to support them.

Standards-Based Web Design Is Best
If you design for Web standards then your Web site will be functional with every browser that supports those standards. And even long into the future, your site will stay functional.

But Internet Explorer 6 and 5 are not standards compliant. So what do you do? The common response is to design just for them and then try to force your site to look okay in standards compliant browsers like Firefox, Safari and Opera. But this is both backwards and difficult.

How to Design for Internet Explorer

1. Build your site for Firefox or Safari first.
Build your site and test it using Firefox or Safari first. This will insure that your Web pages look good in standards compliant browsers. And it's actually fairly easy to do.
2. Use a DOCTYPE.
I prefer to use XHTML 1.0 Transitional, but another good one is HTML 4.01. By using a DOCTYPE, you insure that your page isn't displayed in quirks mode, and the browsers act the same.
3. Once you've got it looking perfect for Firefox, then start editing for IE 6 or 5.
IE 6 or 5 should come last because it's not standards compliant. When IE 7 comes out, your page will look correct because it looks correct in the other standards compliant browsers.
4. Don't use hacks to design for IE.
Instead, use the cascade and valid CSS properties and selectors that IE 6 and 5 don't recognize to hide styles for standards compliant browsers. Put the IE 6 styles first in the cascade - then the standard-compliant properties.

Hiding Styles from IE 6

It's actually really easy to hide styles from IE 6 but make them visible to standards compliant browsers. Use child selectors.

In one design I built, I created a two column layout that required margins and padding. This meant that I was hitting the box model differences when I viewed the page in IE 6. My first CSS style sheet for Firefox included a line like this:

div#nav { width: 150px; margin-left: 20px; }

This made the page line up perfectly in Firefox and Safari, but in IE the nav column was pushed over to the right too far.

So, I converted the line to use child selectors. The #nav div is a child of the body tag, so I changed the line to read:

body > div#nav { width: 150px; margin-left: 20px; }

Of course, doing this made the #nav div lose all it's properties in IE, so I needed to add in some IE styles to get IE 6 looking okay. I added this line to the CSS:

#nav { width: 150px; margin-left: 10px; }

The placement of this line of CSS is important if my page is still to look good in Firefox and Safari. The IE line needs to come first. Firefox and Safari will read that line and then it will be over-ridden by the body > div#nav selector lower in the document. IE 6 will read the first line and set the styles. It will then ignore the child selector, as it doesn't recognize them. When IE 7 comes along, it will act like Firefox and Safari.

By designing for a standards-compliant browser first, and then modifying your CSS to support IE's quirks, you spend a lot less time fiddling with the design and a lot more time actually designing.
