Content Security Policy is a standard developed by Mozilla designed to protect against cross site scripting (XSS) attacks. Cross site scripting attacks use vulnerabilities in websites to inject JavaScript code into pages or urls of that site. The injected JavaScript code is then executed when visitors open a specifically prepared link or page on the [...]

The standard history page of the Google Chrome web browser is a mess. All visited web pages are listed in order of visit, with no options to filter the items by date, name or frequency of visits. Only the search at the top offers some form of customization, as it can be used to find [...]

Last month Mozilla published a list of slow performing add-ons for the Firefox web browser. The findings back then were that add-ons increases the startup time of the web browser by ten percent on average. That’s a lot, considering that five add-ons would on average increase the browser’s start-up time by 50%. The basic idea [...]

I sometimes miss to look at a link destination before I click on the link in question. That is usually not a problem unless it does not point to a website but a file. Depending on the configuration, this may open or execute the file right away on the computer, or display a prompt. PDF [...]

If you are a user of the highly popular classifieds website Craigslist you may have asked yourself if there is an option to display attached images right on the general listings page and not only on the individual pages. You can enable a single thumbnail image on Craigslist with a click on the show images [...]

While I’m still busy changing my passwords, I’m noticing several browser related news popping up in my RSS feed reader. So what’s going on today? Several websites reported that the first beta of Firefox 5 was released, and while it certainly looked that way on first glance, it turned out be a beta labeled Aurora [...]

Find That Band is an add-on for the Firefox web browser that simplifies the process of finding bands or artists on the Internet. Say you have just discovered a new band on YouTube, or received a recommendation from a friend to check out the next big music gig in town. You could now open a [...]

Adobe announced in January that they would better integrate Flash Player with browser privacy controls for managing local storage. It basically meant that the storage of future Adobe Flash Player versions could be controlled directly by a web browser’s web history deletion options. Flash Cookies, or local shared objects, are stored outside of the browser’s [...]

One of the more annoying things on Facebook.com as of late is a relatively new feature called Facebook Questions. It basically allows anyone on Facebook to create polls. These polls then appear not only on your own Facebook wall, but also on the news feed of your friends, which can be pretty annoying when a [...]

It is starting to get crowded on my hard drive, with all the stable, beta and development browser builds stored on it. Opera Software has just announced Opera Next, a development channel for Opera snapshots, similar in functionality to Google Chrome Dev or Canary, or Firefox Aurora. Opera Next can be run alongside Opera stable [...]

I sometimes like to view or listen to YouTube videos multiple times. To bad that there is not an option to repeat YouTube videos automatically. Sure, you can click the Replay link once the video has stopped playing, or refresh the page on YouTube to start from the beginning; But that’s not automatic. It is [...]

One of the biggest features and strength of the Firefox web browser is its extensions engine and the support it receives from the Firefox community. Users find thousands of different add-ons for virtually any purpose in the official extensions gallery over at Mozilla. Mozilla tries its best to promote popular and interesting add-ons, but the [...]

A link points to another web address, device or service. It is usually accompanied by link text that describes the link. But not every link is equal, as the platform used to display the link may have certain requirements. On some platforms, you can simply paste the web address into the form and the software [...]

A common attack form on the Internet is to optimize web pages or domain for specific keywords to make them appear on the first search result pages of popular search engines such as Google or Bing. The attack is enabled once the page or domain receives first visitors from the search engines, which are more [...]

The latest Google Chrome Canary builds have a new feature called multiple profiles which has to be enabled on the experimental flags page of the browser. The new features enables the use of multiple profiles in the web browser, which is in some regards similar to how Mozilla is handling multiple profiles in the Firefox [...]

Mozilla is currently distributing an update of the Firefox 4 browser to worldwide mirror servers to be prepared for the update rush once the updating notification appear in the web browser and on the official project homepage. For now, no sign of the update is visible on the homepage or in form of notifications in [...]

Different teams and individuals are working on the Firefox web browser. Some are improving the web browser’s core, others are working on the interface or experimental extensions that may one day be added to the web browser’s core. One of those experimental spin-offs is the AwesomeBar HD which is now available as a beta release [...]

Google has just updated the Google Chrome Stable channel to version 11. This is a landmark considering that the stable branch of the browser is now sharing the “highest-browser-version-crown” with Opera Software’s Opera browser. More important than the version bump to 11 are the security updates that have been implemented in the browser. A total [...]

The common way of saving images hosted on web pages in the Firefox Internet browser is to right-click each individual image, select Save Image As from the context menu and browse to a location in the opening file browser. There are extensions available to save multiple images at once. Capable extensions include Image Picker, Image [...]

Google Chrome is the only web browser that offers a direct link to access the storage settings of Adobe Flash Player to delete local shared objects, commonly known as Flash cookies. It still means that you have to click on an extra link to open the settings before you can delete the additional objects in [...]

The sheer volume of excitement about Windows 8 has taken me quite by surprise with more leaks than we ever saw with Vista or Windows 7 in the same time-frame.  The excitement and hype easily matches that of Google’s Chrome OS in the same period of its development, even though when the operating system finally [...]

You sometimes may encounter useful pages that have such an irritating design or page style that you have a hard time concentrating on the contents offered. Maybe it is the blue text on the dark background, or lots of whitespace that hurts the eyes, or links that you cannot distinguish from text. You can run [...]

When you select text in the Firefox web browser and right-click afterwards, you get a custom context menu with options to search Google for the selected term. That option can be quite handy to quickly find information about text on a website without having to type the text in a search form, or having to [...]

One of the thing that’s extremely unhandy when you are working with Firefox preferences is that you cannot access a detailed explanation of a preference’s functionality directly. You have to copy the name, do a search on the web in hope of finding a suitable explanation. This often leads to the Mozillazine entry of the [...]

I only have a handful of Firefox extensions installed all the time. One of them is Multi Links, a versatile link handling extension. I often use it to open multiple pages on a website or forum at once. Say you have a website that posts ten links to images each week, funny cartoons or whatever. [...]

Google caches all websites and pages of that site when it crawls them with its bots. Most cached pages are then linked to from Google Search as well. This can be handy at times, for instance if a website is not responding or down. The cached version provides access to the website’s contents even if [...]

Yesterday I have published a tutorial on clearing the browser cache which is an essential thing to know. Today I’m going to show you how to delete cookies from your PC, which is another basic but very helpful thing to know. This article addresses only standard cookies, not Flash cookies. Cookies are small files that [...]

Ghacks regulars know how to clear the cache of their web browser. I get support emails occasionally from new readers who do not know how to do that, or who, when asked to clear the cache, do not know how to do it. Telling customers how to clear the cache was a regular thing back [...]

When you visit a web page in the Firefox browser that requires a specific plugin to be installed to display all or some of its contents, and you do not have it installed, you see the message “Additional plugins are required to display all the media on this page” on the page with an option [...]

EPUB, which stands for Electronic Publication is an open ebook standard. It offers features such as css styling, word wrap or vector images, and its files – the ebooks – have the extension epub. A lot of ebook related sites on the Internet offer their books in epub format. The format is especially popular on [...]

I occasionally use JDownloader to download files that are hosted on free file sharing hosts like Rapidshare, Filesonic, Oron or any of the other ten thousand file hosting sites on the Internet. I usually copy a link to the clipboard which gets then automatically picked up by JDownloader’s Linkgrabber. That’s comfy for single links on [...]

Widgets have been an integral part of the Opera web browser for a long time. That’s not the case for extensions, which have only been recently added to the web browser. It is probably a good idea to take a look at the differences between extensions and widgets first, before we start the overview. Check [...]

I have removed the search form from the Firefox 4 interface in an effort to minimize the user interface of the browser. When I need to search I either load a search engine’s website right away or enter a search term in the Firefox address bar and use the search engine that’s being used by [...]

You have a few options if you want to remove or hide interface elements in the Firefox web browser. Some elements can be removed from the screen by customizing the interface via the right-click > customize option. Others can be removed directly in the Firefox settings or by editing the about:config preferences. The third and [...]

One of the things that I really missed in Firefox was an option to hover over an image to display a preview of it on the same page. I’m often browsing websites that only display thumbnails, or smaller versions of images, on their pages. It is then necessary to click on that thumbnail image to [...]

We are already at part 4 of the Discovering Opera series and there does not seem to be an end in sight. We are going to take a closer look at Opera Link in this part of the series. Opera Link is a synchronization service that works similar to Firefox Sync or Google Sync. Opera [...]

Big news today for the Google Chrome crowd. A post on the Google System blog outlines a recent change in the browser that affects the Java and Quicktime plugin, and maybe even other lesser known plugins. Probably the easiest way to demonstrate what has been changed is it show you a screenshot of Apple’s popular [...]

Firefox displays a lot of options when you right-click in the web browser. The list of items depends on the element that you right-clicked on, as some entries are only shown if you click on images, text or media contents. When you look at all of the entries you may notice that you only use [...]

We are looking at Opera Widgets in the third part of our Discovering Opera series. You can read about Opera Turbo and Opera Unite in the two previous parts of the series. Most users know widgets probably from their operating system. In Windows they are called gadgets. They are small applications that serve many different [...]

Sometimes when you are searching for a specific file you may use Bittorrent indexers to find it. Most indexers allow you to search their index, and it happens that you have to visit and search multiple sites before you find the download that you have been looking for. Torrent Turbo Search is a free Google [...]

We are taking a closer look at Opera Unite in our second part of the Discovering Opera series. Opera Unite – just like Opera Turbo – was introduced introduced in 2009 by Opera Software. It can be best described as a server or direct sharing module in the web browser. You cannot share anything with [...]

Once in a while I stumble upon information that I want to preserve. Sure, I can bookmark the page to access it at a later time, but what if that page gets deleted or moved? I can also save the HTML page to the local computer, but unless I install an extension that adds a [...]

Mozilla has changed the development process of Firefox significantly after the release of Firefox 4. From a long winded Nightly > Beta > Release scheme to a streamlined 18 weeks release cycle that incorporated a new development channel called Aurora. This guide covers all that you need to know to understand that transition, and it [...]

Google has just released an update for the Google Chrome stable channel that updates the version of the web browser to 10.0.658.205 for all supported operating systems (which means Microsoft Windows, Apple Macintosh, Linux and Chrome Frame). The release is a security update that fixes vulnerabilities in all versions of the web browser. Most notably, [...]

Image browsing can be a lot easier if you have the right tools at hand. Imagine a directory with 50, 100 or even 500 images that are all named similarly and only differ in the last digiits or some characters of the file name. Wouldn’t it be more comfortable to see all images of that [...]

It was more or less clear that Microsoft’s upcoming web browser Internet Explorer 10 would not support Windows XP, considering that Internet Explorer 9 did not support the operating system as well. Windows Vista users on the other hand were caught by surprise that their operating system would not be supported by IE10 as well. [...]

The developers of the Opera web browser have been inventive in past years, and it is a confirmation of their hard work that many of the features that they have introduced in Opera are now part of nearly every other Internet browser as well. Not all features on the other hand have been “borrowed” by [...]

I’m used to a very fast Internet broadband connection, pages usually display in less than a second or two, and I rarely ever have to wait longer than that. This changes noticeably when I use a wireless connection to connect to the Internet. Speed is terribly slow and connections sometimes reset for no apparent reason. [...]

Nope, this isn’t a belated April fool, with Microsoft’s Internet Explorer browser only just out of the door and not even delivered to many users yet through Windows Update, the first platform preview of their next version, IE10 is already available to grab at the Microsoft IE Test Drive website. The first demonstration of the [...]

SEO, or Search Engine Optimization, has become a huge part of a webmaster’s day to day work. Not of all webmasters, as it is quite possible to outsource SEO to companies. But if you are a starting webmaster, or on a tight budget, you do not have much choice but to do most of the [...]
