Context: Toggle On/Off Chrome Extensions in Different Contexts

Chrome is great for its speed and expandability of features thanks to the variety of extensions.  However, the more extensions we installed in Chrome the more likely the browser’s speed be lowered (extensions eat memory and CPU power)!

Today’s featured Chrome extension is Context, a tool which allows you to group different extensions and selectively turn them on/off as and when needed.  In this way we could minimized the consumption of system resources.

Context Chrome Extension

 

The first thing to do after installing Context is to create contexts.  You can give each context an icon for easy identification.  Then, drag and drop the extensions you would like to use in each context.  Save the settings and everything is ready.  You would see all extensions originally on the right of the address bar disappeared.

Context Chrome Extension

You now can choose which context to apply.  Click the icon to the right of the address bar and choose the applicable context.  Only those extensions you added in this context would be enabled.

HTTPS Everywhere: Force Open Secure Connection in Firefox and Chrome

It is a well-known fact that unprotected HTTP protocol is prone to hijacks, HTTPS provides better security.  However, while some web sites support HTTPS protocol, only HTTP is set as default.  Some web sites provides HTTPS protocol support but the pages also contain links to unprotected HTTP pages.

Today’s featured browser extension is HTTPS Everywhere, one that forces your Firefox and Chrome web browser to use HTTPS protocol on supported web sites.

 

HTTPS Everywhere: Auto-rewrite of Requests to HTTPS

HTTPS Everywhere - Electronic Frontier Foundation

HTTPS Everywhere has a Firefox add-on as well as a Chrome extension.  What it does is to automatically re-write all requests to unsecured HTTP pages to HTTPS, if HTTPS is supported.  Currently over 1400 web sites are supported, on these web sites this tool knows where to enable HTTPS on all supported parts of the site.  In other words, HTTPS Everywhere does not create the security features, it only enables them when available, so that you don’t have to find the link to secured log-in or the option to enable HTTPS protocol.

The new Chrome extension is currently in beta version.  The Firefox version has one particularly useful feature that is yet to appear in Chrome, Decentralized SSL Observatory.  This function, once enabled, detects encryption weaknesses and tells you when you browse a web site with a security vulnerability.  In other words, it points out security issued as you surf.  This is useful to web surfers as well as web designers who could quickly identify potential security holes.

Internet is the most effective communication tool nowadays, yet due to limitation in technologies, some people with varying degrees of accessibility issues may be unable to enjoy the internet as much as we do.  This article introduces a few accessibility extensions for Chrome and Chrome OS that helps these people to browse the web.

 

ChromeVis

Many info sites such as newspapers and blogs contain lot of words, to put as much information on the page as possible the texts are usually quite small.  ChromeVis is a a handy tool to address this issue.  It magnifies and highlights texts.  Simply choose an text, ChromeVis will display an enlarged version of it on top of the page.  You can choose the background and text colors to create a high contrast.

ChromeShades

ChromeShades is designed to help blind users.  It re-formats a web page in a way that simulates how a blind user would perceive it with a screen reader.  The final outcome is a much simplified web page without losing (most) interactive features.  For web developers who want to create accessible web pages, this tool helps them to identify issues before opening a screen reader or send it to a tester for testing (but it is not a full .  Below are a few illustrations I found in the user manual:

ChromeVox

ChromeVox takes one step further by directly reading out the texts on page.  There are many text-to-speech apps out there, what’s so special about this function?  Firstly, ChromeVox has a number of keyboard shortcuts to help users to navigate around the page.  For example, you can jump to the next heading directly.  Users can control the level of navigation, e.g. jumping between objects (for instance, bullet points), sentences, words and characters.

Secondly, this extension guides users by sound.  When finished loading the page, you hear a beep sound telling you that the page is ready for navigation.  It could read out the texts on the page and the menu items of Chrome.  Watch this video (with video descriptions) to know more:

How to Check Image Properties on Web Pages Instantly

Sometimes you may want to know the properties of an image on a web site, probably since you want to download it as wallpaper, download it as clip art for your own site, save and print it, forward to friends…  You would want to know the dimensions of the EXIF data, image, file size, URL and some other details.  The Chrome extension introduced today, Image Properties Context Menu, helps you to achieve this without having to download the file to your hard disk first.

 

Check Image Properties on Web Pages Instantly

Image Properties Context Menu Chrome extension brings up a new window that reveals the following information:

  • EXIF Data
  • Location (URL of the page)
  • Source
  • Dimensions
  • Original dimensions if the image is shown resized
  • Alt text
  • File Size
  • MIME Type

Image Properties Chrome Extension

One thing I particularly like about this extension is EXIF data display.  I like shooting photos and studying other people’s photos.  If I found a great shot, I would like to know the aperture, exposure time and ISO settings.  I may even want to know the camera the photographer used to take that picture.  Instead of downloading the image file, I can directly check these information right in Chrome.

If you are a web designer, this is also a helpful tool for finding and downloading clip arts.  You can know if the image is large enough to fill a particular space on the web page.  You copy and paste the URL of the page and the image URL to your clip book for re-use later.

Boomerang: Send and Receive Emails at Scheduled Time

Every Monday I review web apps and share tips of productivity and work management. SUBSCRIBE to RSS feed or email updates to know more!

Today’s featured productivity web app is Boomerang.  It is not precisely a web app, but a browser add-on that modifies how you send and receive emails in GMail.  With it, you can schedule the delivery time of your emails, no matter sending and receiving.

 

Boomerang: Scheduled Email Delivery

You can download the browser extension of Boomerang from is official web site.  It supports Chrome and Firefox.  After installing it, you can find the logo of Boomerang next to your email address in Gmail’s screen.

Boomerang for Gmail

Now, if you draft an email, you can find a new “Send Later” button to the right of “Send”.  You can choose to send out this email at your specified time.  You can also choose a pre-defined delay time such as 1, 2, or 4 hours.

Boomerang Send Later

On the other hand, in every received email there is a button to specify a time when you re-receive this email.  What does it mean by re-receiving an email?  Well, when the time comes the email will return to the Inbox and retain unread status.  It looks like a fresh email you just received.

Boomerang Receive Later

Have a look at this video for how it works:

 

Summary

How can you use Boomerang?  For sending, you can use it to schedule emails to be sent to others.  This is quite useful if you can only draft email when you are free but want to send it out later.  Besides, you can also create email reminders by sending emails to yourself (despite you can do so by using Google Calendar as well).

For receiving emails, this browser add-on can help you with avoiding information over-load.  Every day I receive over 50 emails but could only read about 20.  The other 30 emails are not useless, they are simply less urgent.  I tried to put them in folders but for most of the time they just stay there without me touching them.  By putting them again in the inbox, I have another chance of seeing them in front of me.

If you have similar email delivery needs as mine, Boomerang is a browser add-on you should try.

Integrating YouTube and Chrome to Google+

Looks like Google is continuously bringing new features to Google+.  We just reported about What’s Hot, Ripples and Creative Kit, now Google just announced some other small additions.

 

YouTube in Google+

You may now find a small YouTube tab on the right hand side of the Google+.  If you hover your mouse cursor on it, a sidebar bar would slide out for you search for YouTube videos.  It will bring up a new window showing video clips relevant to your search term.

YouTube in Google+

So what’s the intention behind this new feature?  Google said “we wanted to bring YouTube directly into Google+—as well as make it easier to watch and share your favorites“.  Yes, while you can watch the video directly in the new pop-up window, you can also +1 it.

Besides, now when somebody shares a video with you, apart from watching the video, you can also open a related playlist directly from the post.  And Google+ will start to add YouTube playlists in the search results of Google+ as well.

YouTube playlists in search in Google+

This may look strange in the first place but it’s understandable.  People are more attracted to graphics and video, particularly video.  I believe that the better integration of YouTube into Google+ is a move that Google makes to make users stay in Google+ and use it more.  So as the recent addition of the image editing function.  The more cool things people share, the more people use Google+.

 

New Google+ Extensions for Chrome

Google released two new extensions for Chrome for using Google+.  The first one is a +1 extension that lets you +1 any web page, no matter the page has a +1 button built-in or not.  The other one helps to you check Google+ notifications and enable Hangouts right from the extension.

You can find these two extensions on a dedicated page: http://www.google.com/chrome/intl/en/p/google-plus.html
