Chrome: Heavy Google Docs users know it can be a pain when you get an email with an attachment—even if it's in Gmail—and want to save it in Google Docs for later. You have to view the attachment first, and then click to save it in Google Docs, and even then only if it's one of a few file types. With the Gmail Attachments to Docs extension for Chrome, saving one or all of your attachments is as easy as clicking one link. More »

Chrome: "Bus Times for Google Maps" is an extension that lets you quickly view upcoming transit times for your favorite public transportation routes by just clicking or hovering over an icon at the top of your browser window.

Wikipedia Beautifier is an extension for Google Chrome that removes all the clutter from Wikipedia and lets you focus on the most important aspect of the online encyclopedia: its content. Wikipedia Beautifier has been inspired by Readability, and aims to provide the same amount of article-centered beauty, while also keeping the familiar navigation menus within reach.

I don't often need to open a PDF file, and when I do it's typically something I'm looking at in my Web browser. Since I'm using Google Chrome, the built-in PDF viewer is what I use 90% of the time. I do, however, get the odd email at my day job (where we don't use webmail) with a PDF attachment I need to read.

So I thought, "why not open those in Chrome, too?" It's easy enough to set up. Here's how to do it.

First, locate your Google Chrome executable. The easiest way to do this is to right-click your Chrome shortcut and choose properties from the menu. In the box labeled target, you'll see the complete path to Chrome.exe. Highlight that text and copy it to your clipboard.

Kindle owners who would rather read web articles on their Kindle devices than on a laptop screen are in luck: there's now a Send to Kindle Chrome extension. With a little bit of setup, you can pass articles to your Kindle over Wi-Fi or Amazon's Whispernet with one click.

When you install Send to Kindle, you'll see a setup screen where you'll have to enter your Kindle's registered email address. Then, jaunt over to your Kindle Management page at Amazon and add the extension's email address -- "kindle@klip.me" -- to your list of approved senders.

BleachBit -- the open source system clean-up utility for Windows and Linux -- has added several new features to its latest version that make it an even better tool for removing unneeded files files from your computer. Support for Google Chrome and Chromium has been greatly improved: BleachBit can now remove everything from DNS prefetch data, to autofill history and DOM storage. Support for HTML5 localStorage cleaning has also been improved and now works with Opera.

On Linux systems, BleachBit can now remove swap files (in addition to swap devices). The Windows version has added the option to remove Windows Update uninstallers -- including hotfixes and Internet Explorer patches. BleachBit's list of supported programs has also grown significantly since we last wrote about the program, and it's well worth checking out the full list of features to see just how much digital crud it can remove from your hard drive.

Voice Search is an extension for Google Chrome that allows you to speak search queries instead of typing them, and it's not limited to Google searches.

It works very similar to the voice input system that Google has built into Android. A microphone icon will show up in your browser's extensions area, as well as near any HTML5-powered search box on websites that it can be used for. To search for "kittens", the developer says, just click on the microphone and say "kittens". To search Google Images for kittens, say "google images kittens". To search Wikipedia, say "wikipedia" followed by your query.

Voice Search can search using the following sites by default: Google, Wikipedia, YouTube, Bing, Yahoo, DuckDuckGo and Wolfram Alpha. However, you can also add other search engines that you like.

This is at a very experimental stage at the moment, and as such you may find that you need to start Chrome with the flag --enable-voice-input for the add-on to even work. Instructions on how to add the flag are available on the app's page in the Chrome Web Store, which is also where you can download Voice Search for Chrome for free.

So the Chrome Web Store is upon us, and I decided to cover my first Web Store application for Download Squad. Rather than aiming for something high-profile like the Tiger Woods PGA Tour Online app, I decided to go with Metrodome!

Yes, it's just a humble metronome, but it's graceful. It comes with three different sound options (a "tick", a "beep" and a "tock"), all quite pleasant-sounding. But what I like best about it is that it shows a huge dot right in the middle of the window, that goes on and off to the beat. This makes it possible to play by eyesight rather than by listening to the metronome, so you can jam with your headphones connected to your amp and just watch the metronome on-screen.

You can set the BPM, of course, but only by clicking the up/down arrows. This means you're in for a lot of clicking if you want something drastically different than the default (120bpm). This is actually the only extra feature I wish this metronome had. Other than that, it's a beaut!

There are a ton of add-ons that dim the screen while you're watching a video or playing a Flash game. Heck, some Web sites even have this functionality built right in, no add-on required.

Reading Glasses for Chrome does the same, but for text. As you can see in the screenshot, with Reading Glasses, only the post text is dark, while all other page elements are grayed out. This is accomplished by highlighting some of the text of the post, and clicking the "glasses" icon which appears next to the address bar once the add-on is installed.

I wish the add-on could make the page background dark and the text light. Also, it would be nice if it could make the text a tad larger. Then again - this is what Readability is for. Then again, Reading Glasses is a bit more lightweight and it doesn't impact the site's look-and-feel at all, except for fading it out a bit.

Stylebot is a Chrome add-on that provides a point-and-click interface for customizing the CSS on any page, and then it saves your customizations for next time -- and if you have bookmark sync turned on, it even syncs them for you!

The way that it works is very simple. In Selection mode, each element on the page gets a highlighted frame when you hover over it. As soon as you get the element that you want, just click it. Any CSS declarations that you then specify are applied to that element.

"Specifying CSS declarations" sounds pretty technical, but it's basically clicking a bunch of buttons. You need to know a bit of CSS to make good use of the add-on, but it's also a very good way to learn. Of course, if you do know your CSS, you can just switch to Advanced mode and hand code it instead.

A few missing features:

• Up/down keys do not work for incrementing/decrementing values. That's a must-have Greasemonkey feature!

• Existing font sizes (and other properties) are not displayed. This means that, if I want to increase the font size of an existing element, I need to start by guessing what the current size is. Then, I need to nudge it up by entering (say) 12, deleting, entering 13, deleting, entering 17, deleting, entering 15, etc. It rapidly gets annoying. Up/down keystroke support + showing the currently selected font size would go a long way towards alleviating this.

• There's no simple way to undo a single change. You can either reset everything you've done, or you can manually edit the CSS in order to remove the change (if your CSS chops are up to the task).

Other than those few things, it's certainly a handy add-on for customizing the Web. I like that it saves your settings automatically and syncs them. I've embedded the add-on's "intro video" after the break.

Chrome is a terrific browser on its own, but FastestChrome makes it even better. It adds extra search options to the Omnibar, creates "endless scrolling" for multi-page articles, fixes text-only URLs, and tunes up other Chrome features.

FastestChrome gives search a big boost, adding other search engines, displaying related articles from Wikipedia, and even showing related results from Amazon at the top of your Google results page. Highlight text on a page, and a customizable bubble pops up to let you search that string of text in Google, Delicious, and even Twitter. FastestChrome also turns text URLs into links, making navigation a lot quicker.

Options are easily turned on and off by clicking the extension's settings button in your toolbar. Once you've checked out FasterChrome, have a look at 18 other extensions we think are worth downloading (and, hey, maybe 13 more?).
