Scrolling Problem in FireFox

[Ephraim]

Well, Firefox being my favourite browser, for last couple of days it is behaving strangely while scrolling. What happens is instead of the down arrow key moving the screen a line or two, and the Page Down is dominately moving down a screen, so that it jumps to the end of a blog.
Why is this happening ? Any reasons....
How do I fix it ?

The behaviour you describe seems to be the issue of ctrl-pagedown key. Maybe your computer has a stuck ctrl key. Hit the ctrl key a few times to see if it unsticks...

Here is the solution for your problem:

1. Under Options >> Select the Advanced tab >> Accessibility Options will appear.
2. Under Accessibility Options >> one choice says "Allow text to be selected with the keyboard" >> That option would be checked.
3. You unchecked it and the problem will be solved.
4. Now you can use your spacebar to scroll down web pages.

The browser scrolling problem is caused by the so-called Caret Browsing.
It is turned on (and off) by pressing F7.
However, reinstalling Firefox (or updating to a new version) does not change your settings, and the effect will not go away.
Just press F7.
