Change Firefox Disk Cache Location
Firefox has two types of cache which is the disk cache and memory cache. By default Firefox takes up 50MB of your hard drive space to be used as disk cache. The cache are meant to make website loads faster and saves your bandwidth if you are visiting the same website that uses the same images which are not modified. If you are downloading a file, it is also temporarily saved in disk cache and when the download has completed, Firefox copies the completed file to the Downloads folder.
By default the disk cache location can be discovered by typing about:cache in the address bar and hitting Enter. The disk cache device area will show the cache directory. If for some reason you want to move your disk cache directory to another path for easier access or probably you have moved your Firefox profile to a small RAMdisk and the cache is taking up unnecessary RAMdisk space, then here is how you can change your disk cache location.
1. Type about:config at the Firefox address bar and hit Enter.
2. Type browser.cache.disk.parent_directory in the filter bar and hit enter. If it shows blank, then right click anywhere on the blank page and select New > String.
3. Enter the preference name as browser.cache.disk.parent_directory
4. When asked to enter a string value for the preference name that you have just created, enter the full path of where you want to disk cache to be and click OK. For example, C:\FirefoxCache
5. Restart your Firefox browser to take effect
You will find a Cache folder in path that you have specified. If you specified C:\FirefoxCache, the Firefox cache files are stored in C:\FirefoxCache\Cache\
Show Only Image From Image Hosting Websites such as ImageShack
There are many image hosting websites that allows users to upload images, photos and pictures which allows anyone to view it publicly by sharing the link. However there are a few types of links provided by the image hosting site such as the link, direct link, widget code, forum code, alt forum code, HTML code, forum thumnail, alt forum thumbnail and HTML thumbnail. For a user that don’t know much about computer, most probably they will be sharing the link instead of direct link.
The different between the two links are the link sends the user to the image hosting website with a lot of garbage on the page such as advertisements and etc. As for the direct link, it is a link only to show the image and nothing more.
Firefox will require GreaseMonkey extension together with the userscript and Chrome with just the extension called Show Just Image to remove all the junk from the normal image hosting link and showing only the image. This saves you from having to click another time on the thumbnail to zoom and view the image in full. Show Just Image currently supports 90 image hosting sites including some of the popular ones such ImageShack, Photobucket, flickr, tinypic… There is nothing you need to do, just install and the extension will detect and redirect automatically to the direct image link.

Open Gmail Account for MailTo Protocol in Firefox without Gmail Notifier
Google offers a free software for Windows and Mac called Gmail Notifier where it can designate Gmail as the default mailto handler. When the software is installed, there is an option where you can set the program to hook the mailto hyperlink and upon clicking on it, a Gmail compose window will open so you can send email directly to that address from Gmail.
We have nearly covered all of the web browser on how to use Gmail as the default mailto handler except for Firefox and Safari. Safari does not have an option for you to set the mailto handler so you must use Gmail Notifier. As for Firefox, it has a built-in option to set the action for a content type.
Click on Tools at the menu bar and select Options. Go to to Applications tab and type mailto in the Search box. All you need to do now is to click the drop down menu for the action and select Use Gmail. Now whenever you click on any hyperlinked email address on a webpage, Gmail will automatically open and after login the compose page will be loaded together with the email address and relevant information specified in the hyperlink.
Disable Additional Plugins are Required to Display all the Media on this Page Bar
Firefox provides better security compared to Internet Explorer, hence installing it on public computer that is being shared with many people is a wise choice. However if for further security reasons you don’t want to install Adobe Flash Player for Firefox, the user will end up getting a warning bar at the top saying “Additional plugins are required to display all the media on this page” whenever they are visiting a website that uses flash. Weirdly there is no option to disable this annoying bar and it keeps showing until you press the Install Missing Plugins button.

One simple way to disable the warning bar asking you to install additional plugin is to type about:config in the Firefox address bar and click the I’ll be careful, I promise! button. At the filter bar, type plugin.default_plugin_disabled and press enter. You should see that the value for this name is true. Double click on this item to change the value to false. Takes effect immediately without restarting the browser.
Disabling the Shockwave Flash plugin from the Plugins window is not good enough because when visiting a webpage with flash, it will display the message “The plugin for this content has been disabled. Click here to manage your plugins.” Upon clicking on the icon will open the plugin window which allows the user to re-enable flash.
Removing Firefox Red Wavy Lines on Typed Words
Firefox comes with a lot of features by default and the list grows tremendously if you look at the available extensions that provides extra features that is not found in Firefox. One of the useful Firefox feature is the spell check where it auto checks the word that you type and if found that the word does not include in the dictionary, the word will have be underlined with a red wavy line to indicate that the word might be wrong and offers a few suggestion.
If you are a blogger or writes emails in webmail, you might want to remove those technical terms or jargon that are not included in the dictionary. This saves you time when you are checking for any typing errors. One example of a word that is commonly used but not included in the Firefox dictionary spell check is the word “webmail”. When you type the word Webmail, Firefox offers a few suggestion such as Web mail, web-mail, webmaster, webmistress and seamail.

To easily add the word to dictionary all you need to do is right click on the red wavy line and select “Add to Dictionary”. This is easy and you might have already noticed this and done this. However if you have added a wrong word to the dictionary, removing it might take slightly more steps. You will need to go to your Firefox profile folder by typing %appdata%\Mozilla\Firefox\Profiles in the Search programs and files bar in Start Menu. Then there should be a folder with random letter and number. Enter the directory and look for file name persdict.dat. Open it with a text editor such as Notepad and the words that you exclude from spell check are listed there. The entries in persdict.dat are one word per line.
Check Who Removed You From Facebook Friends Connection

Keeping track and maintaining your friend lists in Facebook is not going to be easy if you have few hundreds or probably few thousands. When you have so many so called friends, sometimes people will just remove you from their connection list and you won’t even know. Facebook does not notify you when someone has removed you from their friend list. Although it is still fair because when a friend has removed you from their list, they can no longer see your information and will only see the sentence that says “User only shares some of her profile information with everyone.”
It is still nice to know who has removed you from their list. One of the way to know who has removed you from their friend list connection is by using a Greasemonkey script called Facebook Friends Checker. You will first need to install the Greasemonkey extension for Firefox and then install the Facebook Friends Checker userscript. What this script does is it checks all your friend list every 2 hours and then records it down.
If the script finds that a friend is not in the list, Facebook Friends Checker will notify you that the user is no longer friends with you and there is a link to the profile. This script does not work in real time and it is probable that it could miss out some friends who removed you from their list. You can however change the interval to check for removed friends to 1 hour.

The Facebook Friends Checker script was last updated on 10 February 2010 which contains fixes for the new Facebook redesign.

Add Dislike Button to Facebook with FBDislike Extension for Firefox and Chrome

Whenever people share their photo albums online publicly in Facebook, there is a Like button for people to express that this photo is nice and they liked it. Obviously the more people that clicks the Like button, the more popular it gets. However Facebook development team has been a little bias not to include a Dislike button. The simple reason is Facebook is meant to social and not make enemies, so if you see something that you like, go ahead and click the Like button or else move on.
To be on the fair side, 3 person by the name of Thomas Moquet, David DJIAN and Pascal Filipovicz has created a Firefox and Chrome extension that adds a Dislike button next to the Like button. When you click the Dislike button, the extension sends the dislike information to their server’s database together with the id of item, id and username of the user who dislike the item. If the server is down, (currently it has been down for a few days already because of server problem), the Facebook Dislike feature will not work and will not be seen as well.

There are some scam or spam going on for Facebook Dislike button but this Firefox and Chrome extension is absolutely safe and does not contains any virus or trojan.
