Is it possible that when a website is opened only text data is displayed i.e no image, advertisement etc. so that it takes lesser time to load the website ?Any browser that supports this?
You can manually disable things from your browser - Instructions below for FF and chrome - I don't use IE, but i can check if its your browser of choice.
You can disable load images automatically (which will prevent images from loading) - this is under options -> content on firefox or privacy -> content on chrome
And switch all mimetypes to 'always ask' - this is under the applications tab on firefox and i believe handlers under chrome
I would add screenshots, but that would somewhat defeat the purpose of this question ;)
Ad-blockers are also available as plug-ins/extensions for Firefox, Chrome, and Internet Explorer. I've only linked to a few popular ones, but others are also available. Opera has a built-in ad-blocking feature.
If you have really limited bandwidth, you might want to consider trying Opera's Turbo mode, whereby a web page is downloaded and rendered on Opera's servers, then an optimized version is sent to your browser. The Kindle Fire's Silk web browser has a feature similar to Opera's Turbo mode.
Many websites have mobile-optimized versions which you can access by replacing www with m or mobile. In addition to being optimized for smaller screens, they are also often optimized for lower-bandwidth connections. For example: m.wikipedia.org.
Another website: ViewText.org strips away all the ads and gives a text-only version of any website, but retains simple formatting.
Other alternatives, currently working as of this posting date, are:
ipodulator -- zero formatting, best viewed in long, skinny window
textise.net -- for a long time, THE BEST, but not working so well lately (I take that back - it's working great again. Been rock steady for a few weeks so returned to update answer. I see that the site dev has added his own comment/answer and am happy to strongly recommend this site.)
textonly.in -- not working so well
You can also accomplish this locally using the correct extensions in Firefox or Chrome:
If use both Chrome and Firefox, keep one browser always configured for plain text. Else, install a second distro of Firefox, such as Pale Moon (portable version), and keep that always configured for plain text.
Textise (http://www.textise.net) allows most web pages to be converted into neat text and can be accessed via its home page, a Firefox add-on or a bookmarklet. It's also used by many sites for their "text only" links- see the showcase page at http://textise.wordpress.com/showcase/.
As the developer of Textise, I'm concerned about the phrase "not working so well lately" that appears in another answer!
Textise is up and running (faster than ever) and, as far as I know, experiencing no issues. Please get in touch if you're having problems, via the contact form at textise.wordpress.com. Thanks.
