[Tip] Know The File Size Before You Download It In Firefox

Knowing the file size before you could actually start downloading it is good practice as you can plan your work accordingly. For instance if you want to download a relatively bigger file, you might want to postpone it to later without interrupting your current work. Most of the sites especially download portals always show the information about the size of the file before the download. However it is not the same case always. There are times when you download a file and come to know about its size only after the actual downloading begins in Firefox.

Thankfully there is a Firefox ad-on called “Show File Size” that allows us to view the file size information before you download it. Once installed, the extension show information like the type of the file and the size of the file you are downloading it in a separate row just below the name of the file row in the download window as shown:

It is a basic, lightweight extension (just 4KB !) that just serves the purposes justifying the name. Show File Size add-on works fine with Firefox 3.6 to Firefox 4 versions.

[How To] Disable Firefox Taskbar Tab Previews

Multiple tasbar tab previews

Taskbar tab previews is a great feature introduced in Windows 7, with the help of which you can access any opened tab right from your taskbar without opening the browser. This feature was first meant for Internet Explorer only, but later it was adopted by almost all the browsers.

Even though this is a great feature, however it may sometimes annoy you particularly when you open a lot too may tabs in the browser. That’s why we posted a tutorial on how to disable the multiple taskbar tab previews in IE, Firefox and Google Chrome. Now that Firefox 4 is coming with this taskbar tab previews feature enabled, we thought we’d revisit and bring to your attention if you are looking for a way to get this feature disabled in your Firefox. Follow the steps carefully:

Steps:

1. Type about:config in the Firefox address bar.

2. Accept the warning message and proceed (Click “I’ll be careful, I promise) to the configuration page.

3. Type

browser.taskbar.previews.enable

in the filter and look for the entry with the same name as shown in the following screenshot.

4. Change the value to “false” by double-clicking. That’s it. You will only see a preview of the one (active) tab preview instead of the multiple taskbar tab previews.

As Mozilla has made Firefox 4 Beta to be available publicly. My Firefox lovers have already downloaded it and managed to get a first look of what’s in store for the upcoming Firefox 4. Whie we still learn about all the major and minor features introduced in Firefox 4, we thought we would share this minor and handy feature that may interest you. This feature is called “All tabs preview”. It is similar to taskbar-tabs preview, but built right into the Firefox without needing to install additional add ons. By default this is not active in Firefox 4.0, but you can always activate it by following the steps briefed below:

All_tabs_preview_firefox_4

Steps:

1. Type “about:config” in your Firefox address bar and press enter.

2. Accept the warning that you get under “This might void your warranty”. Click on “I’ll be careful, I promise”.

3. Now type “browser.allTabs.previews” and look for a entry with the same name (Preference Name).

All_tabs_preview_firefox4
By default, this has been set to “false” which disables the All Tabs Preview feature in your Firefox 4. To enable this, double click on it or right-click and choose “Toggle”, change the value to “True”. Close the about:config window.

4. You can now spot a new “List All Tabs” icon at the top right hand side, just below the close icon of your window. click on the icon to see the preview of all the opened tabs of your Firefox.

To disable this feature, go back to the third step and change the value of browser.allTabs.previews back to “false”.

Mozilla has recently unveiled a new Beta version (yeah, it’s still buggy and under testing) of  upcoming Firefox version, Firefox 4. Users can get a rough idea about how the upcoming Firefox 4x versions would be by installing this beta version of Firefox. You can download Firefox 4.0 Beta 1 and Firefox 4.0 Beta 2 Pre Build from the Mozilla’s directory of nightly builds links for which are posted at the bottom of this post.

Changes in Firefox 4.0 Beta :

1. New User Interface simple in line with Windows Aero in Windows 7 and Windows Vista also supports the new Glass translucency effect. This version  supports multiple tab previews much like in Internet Explorer 8.

2. The menu bar has been repositioned at the top most left of the windows, which you might have seen in the latest Opera browser too.

3. Another change includes the change in the position of the tabs. Until Firefox 3.6, the tabs are used to be placed below the address bar, which is not the case in this new version. Tabs are neatly placed above the address bar like Google Chrome.
