How can i SLOW [not speed] scrolling speed in Windows FF?

Answer 1

I'm not very familiar with trackballs, but I'll add a comment regarding the keyboard part.

<blockquote>
When i press my spacebar or keyboard arrow key, [all] pages scroll too fast.</blockquote>
On my Firefox, the spacebar skips down a screenful at a time, like the PgDn key. When that repeats, it's certainly going to cover a lot of ground, and a lot faster than the down arrow key. But pressing the spacebar a few times can be efficient if you don't hold it down continuously.
The distance covered by the up and down arrow keys can be modified using a different preference:
(1) In a new tab, type or paste '''about:config''' in the address bar and press Enter. Click the button promising to be careful.
(2) In the search box above the list, type or paste '''scroll''' and pause while the list is filtered
(3) Scroll all the way down to '''toolkit.scrollbox.verticalScrollDistance''' which usually has a default value of '''3'''
* If the preference is bolded and user set to a value higher than 3, use right-click > Reset to set it back to 3 and test how that works for you (test on a normal web page, not the about:config page)
* To reduce the number of lines below 3, double-click to edit and type a smaller number and then you can test that (test on a normal web page and not the about:config page)
Does that help at all?
''Note: I assume you are not using "Caret Browsing" which moves the cursor through the text of the document when you press the up and down arrow keys. The results can be somewhat unpredictable depending on the layout of the page. If you want to test that feature, you can turn it on and off by pressing the F7 function key.''
