Regular readers know that I would make the switch from Firefox to either Google Chrome or Opera if those web browsers would support NoScript functionality and Last Pass.
NoScript is a security add-on for Firefox that blocks scripts from being loaded when the website loads. While that means more work on your part to enable scripts selectively when needed, it blocks many attack forms on the Internet outright.
LastPass is an online password manager on the other hand.
So far only Last Pass has made its way to the Google Chrome browser. Daxpit, a reader of my blog, recently mentioned that the BlockIt userscript offers NoScript like functionality when run in Opera.
A userscript in Opera is an external script that can be loaded in the web browser. Much like add-ons but more complicated to setup in my opinion.
BlockIt is compatible with the latest versions of Opera up to Opera 10.50 which is the version I have tested the script on.
It displays a small icon in the lower right corner of the screen. A click on that icon displays a menu that shows the scripts on the page, the number of scripts that have been blocked, a pulldown menu listing all script names, and controls to unblock scripts on the page.
All scripts that are executed normally on the page are disabled by default just like they are in NoScript.
BlockIt divides the elements on the page into categories like scripts, images or embeds with the option to unblock those elements individually or completely. This is one of the differences between both scripts. NoScript ignores images as they are not scripts whereas BlockIt blocks them as well in the beginning.
The following controls are available:
BlockIt remembers the configuration changes made by the user so that elements that have been unblocked remain unblocked in future sessions. The information are stored in cookies which means that cookies need to be enabled for the settings to be saved by the script.
BlockIt is a great NoScript alternative for the Opera web browser. This ties the score between Google Chrome (which got Last Pass) and Opera (which got NoScript).
BlockIt can be downloaded from the forum page over at the Opera forum where the developer announced the script.
Update: The switch to Chromium brought many changes to the Opera web browser. One of them was a reset of the Opera forum taking all old posts with it. This means that BlockIt is no longer available. Even if it would be, it would no longer be compatible with recent versions of Opera.
You may want to check out the NotScripts extension for the new Opera browser which offers similar functionality.
