Hi,

There are almost 30+ opened tabs in my firefox at any given time. So I scroll over them using muse wheel. But for each notch of mouse wheel scroll, almost 6~7 tabs move left/right.

I would like change this number to 1 tab per notch of mouse wheel scroll.

Is this possible through editing any flags?

Thanks

Reduce scroll distance with mousewheel.default.delta_multiplier_y in about:config and then increase page scroll distance with mousewheel.min_line_scroll_amount to compensate.

Thanks for the tip. It's kind of working as of now. But need to fine tune the values.

The delta_multiplier prefs are internally floats of type double and are converted to an integer for storing in a pref by multiplying them with 100 and are acting as percentages of the default scroll amount (i.e. 100 -> 1). You can try to set this pref to 33 to get a one line scroll. Adjust mousewheel.min_line_scroll_amount to make vertical scrolling work to suit your needs.

  • If line-height is lower than this value (in device pixels), 1 line scroll scrolls this height.
