I am using firefox 4. I want keep the bandwidth usage as low as possible when I am browsing the internet? What options do I get?

If I disable the option of "load image automatically", will still download the images and just block them?

I would like to block image and flash, but I want to know that there is a image/flash there...most of the website do not make use of the alt property, so that I will not be able to know there is a image if I blocked them.

That thread didn't solve the problem really. –  lamwaiman1988 Jun 20 '11 at 4:22

Disable loading of images, JavaScript, all plugins, and automatic add-on updating.

If I block the image, how do I know there is a image? –  lamwaiman1988 Jun 20 '11 at 4:26
    
If there is an alt attribute then that text will show up next to an icon. Otherwise, just an icon. –  Ignacio Vazquez-Abrams Jun 20 '11 at 4:27
    
There are no icons. For example, I blocked all image and refreshed this page, I check the icon next to your username, there is only a blank area, with no specific prompt for the existence of a image. –  lamwaiman1988 Jun 20 '11 at 4:33
    
Strange. They must have removed that then. –  Ignacio Vazquez-Abrams Jun 20 '11 at 4:35
    
The User avatars here don't have an alt text. Try on some other websites (like nytimes.com or similar) –  slhck Jun 20 '11 at 4:36

I use firefox 3.5, but the answer may still be relevant.

I use the following combination:

  • NoScript addon
  • AdBlockerPlus addon
  • ImgLikeOpera addon
  • Ghostery addon
  • Squid web proxy

Between them, they made a big dent in my internet data usage.

NoScript is handy because many scripts download more scripts and images. It also blocks flash. It shows you when it has blocked anything and it lets you unblock them.

AdBlockerPlus stops the browser from downloading ads and the associated images.

ImgLikeOpera gives better control over which images are loaded that the built-in "don't load images" setting. For example, you can tell it to show images that it has already downloaded. This means you can load the images for buttons and the like, and then switch back to "show cached images" mode, and the images are still visible - even when you open the same page later on.

I also use the Ghostery addon. I have it installed for privacy, but I think this stops some (small) downloads.

I have also installed a web proxy (squid). However, it is not that effective: only about 10% of requests hit the cache, the rest are misses that must be fetched from the internet. Still, it helps a bit. The biggest benefit from using the web proxy was analysing its logs, which led to changes in my browsing behaviour (e.g. switching to "basic HTML" mode on google mail, and not leaving a google mail window open), but going through the logs takes effort; it isn't trivial.

Ghostery's lists grow all of the time, so I let it autoupdate its list so that it remains effective. I decided to leave "automatic add on updating" turned on, so that the AdBlockerPlus is updated. I think that on balance this uses less bandwidth than if I left auto-update off, and I don't have to remember to update them myself. However, I could be wrong about this one :)

This eliminates most of the bling, but it does reduce functionality. Some sites only work if I temporarily enable the trackers or ads. Similarly, some sites are almost unusable without images, but some of them become bearably usable if I select "No page style" on the view menu. I decided to live with this level of inconvenience.
