Websites – at least the desktop versions – are designed for broadband
connections and are larger than ever. This isn’t normally a problem,
but what if you’re tethering your computer to a smartphone with a
limited data plan?
These tips will help you use less data and come in under your data
cap. They shouldn’t be necessary if you are on a decent, wired Internet
connection with unlimited data or a high data cap.
1. Enable Click-To-Play Plugins
Many websites include embedded Flash content, often for videos or
advertisements. This Flash content can be fairly large in size. To
prevent Flash content from loading, you can enable the click-to-play
plugin feature in your browser. When you access a page containing
content that needs plugins – usually Flash, but occasionally Silverlight
or something else – you will see placeholder images\. Click the
placeholder and the content will download and play.
With click-to-play plugins, plugins won’t run automatically. They
will only download and use your bandwidth if you actually want to view
them.

You can also whitelist websites, allowing them to always load plugin
content without asking you. This can be useful for websites like
YouTube, although you should consider using low-quality settings on
YouTube and other streaming video websites to limit data usage while
tethering.
2. Disable Images
Images still take up quite a bit of bandwidth, and this has only
increased as websites include images that are larger and more detailed.
However, most websites can be used without images.
Follow these instructions to prevent your browser from loading images automatically:
- Chrome: Open the Settings screen, click Show advanced settings at the bottom, and click the Content Settings button under Privacy. Select Do not show any images.
- Firefox: Open the Options window, click the Content icon, and uncheck Load images automatically.
- Internet Explorer: Open the Internet Options window, click the Advanced tab, scroll down to the Multimedia section, and uncheck Show pictures.
- Opera: Open the Preferences window, click the Webpages tab, and select No Images in the Images box.
3. Use Opera Turbo
Opera Turbo is a unique feature not available in other popular
browsers. When you enable Opera Turbo in Opera, web pages you visit will
be routed through Opera’s web optimization proxy. The proxy compresses
images and other parts of web pages, shrinking them and making them take
less bandwidth. This is similar to what Opera Mini, one of Opera’s
mobile browsers, does.
To enable Opera Turbo, click the Opera Turbo icon at the bottom of the Opera browser window and select Enable Opera Turbo.
Opera will never route secure HTTPS pages through their proxy. This
helps preserve your privacy when viewing sensitive data, but it means
that some pages won’t be compressed.
4. Disable Automatic Browser Updates
You should update your browser regularly — automatic updates are the
ideal way of doing this. However, if you’re tethering, you probably
won’t want your browser to suddenly download a large update over your
cellular data connection.
- Chrome: Google provides instructions for disabling Google Update on Windows.
- Firefox: Open the Options screen, click the Advanced icon, click the Update tab, and temporarily disable automatic updates.
- Internet Explorer: Internet Explorer updates itself through Windows Update. See below for more information on tweaking Windows Update’s settings.
- Opera: Open the Preferences window, click the Advanced tab, select Security, and select the Notify me about available updates setting in the Auto-update box.
Note that leaving automatic updates disabled is a security risk. You
should re-enable automatic updates when you have access to a proper
Internet connection.
5. Disable Other Downloading and Uploading Applications
This isn’t a browser tip, but if you are tethering your computer and
using a mobile data plan, it’s crucial. Many other applications use the
Internet and will chew through your data allotment if you let them.

You will probably want to tweak Windows Update’s settings. Set
Windows Update to prompt you to download updates, not download them
automatically. (Open the Windows Update control panel and click Change
Settings to access these settings.)
You should also close any other data-hungry applications you use,
including Dropbox, Google Drive, SkyDrive, Steam, iTunes, or anything
else using data – even an application that just downloads automatic
updates for itself. Keep an eye out for these data-hungry programs.
You will probably want to undo many of these tweaks when you get back
to Wi-Fi, as Opera Turbo will slow things down on fast connections and
browsing the web without images can be obnoxious.
