One of the most useful functionality in Firefox is a button to subscribe to RSS, if the website we visits has a RSS feed. The button is always in the right-most of address bar. But, since Firefox 4.0 the button is missing from the address bar. I though this functionality is deprecated, but luckily it’s not. The button is shown on the toolbar by default anymore.
In order to show the RSS Subscribe button you have to click on Firefox menu -> Preferences -> Toolbar Layout. From here a Customize Toolbar window will be shown, like shown below. Find the RSS Subscribe button and then drag the button to the toolbar. You can choose the place in the toolbar as you like. For example, I put the button at the right side of the address bar, just besides Home button.
Ubuntu always sticks to a version for every software that delivered in an Ubuntu version. Like Ubuntu 10.04 always sticks to Firefox 3.6. Its only update the Firefox if there is an update for Firefox 3.6. It’s applicable to all of the software in Ubuntu.
Firefox 5 has been released for quite sometimes. And, Firefox 5 is way better than Firefox 3.6, such as simplicity, speed, and overall appearance. Staying with Firefox 3.6 is like torturing yourself, while the Firefox 5 is sitting in the shop, waiting for us to take it home. On the other hand, I have no intention to upgrade my Ubuntu to the latest version.
Fortunately, there are 2 ways to upgrade our Firefox. First, download Firefox (tar.bz2 file) from Mozilla website, and install it manually. Second, install it using Ubuntu Software Center. I prefer the second method, because it has been tested by Ubuntu team.
In order to do this, you have to add PPA for Firefox into software repository list. There are 2 ways to do this:
- By using GUI, open up the Ubuntu Software Center, click menu Edit > Software Sources and click the ‘Other Software’ tab. Click ‘Add’ and then paste ppa:mozillateam/firefox-stable into the APT Line input box. Once done you can click on menu System > Administration > Update Manager to perform an upgrade.
Ubuntu Software Center
- By using terminal, you just need to run these command in the terminal window:
- sudo add-apt-repository ppa:mozillateam/firefox-stable
- sudo apt-get update && sudo apt-get upgrade
The Ubuntu Update Manager will upgrade your Firefox to the latest version according to its PPA, including automatically upgrade to Firefox 6 by the time it released. Have fun. 🙂
In the first day I thought the problem was because a problem in Facebook. After a few days I noticed that some of my friends didn’t have problem with Facebook, even though I didn’t know what browser that they used.
Yesterday I fixed the problem. Looks like it because the offline website data in my notebook cause the problem. Yesterday I cleared all the caches, cookies, and offline website data, and then my facebook’s look backs to normal.
