hello Jérôme Caron,

Using Windows 10 on an Asus laptop. I have problems with Firefox hanging, and with scrolling. It is bad on the New York Times web site. First nothing happens when I try to scroll down, then it scrolls too far. I have also had problems with "unresponsive scripts" and I don't know if upgrading to 10 has changed it. What can I do? Actually it is slow right now. I am typing very slowly and have to wait for the letters to appear.

You can try to disable hardware acceleration in Firefox. Tools > Options > Advanced > General > Browsing: "Use hardware acceleration when available" You need to close and restart Firefox after toggling this setting. https://support.mozilla.org/kb/Troubleshooting+extensions+and+themes You can check if there is an update for your graphics display driver and check for hardware acceleration related issues. https://support.mozilla.org/kb/upgrade-graphics-drivers-use-hardware-acceleration

Turn on 'Smooth Scrolling' Start Firefox. Click Tools, Options. Click the Advanced icon, then look in the Browsing section. Enable Use smooth scrolling, then click OK.

To enable the smooth scrolling function on Mozilla Firefox, follow the simple guidelines below:

Launch Firefox. Type about:preference in the address bar and then hit the Enter key.firefox about preferences Smooth Scrolling On the displayed window, locate Browsing and check the Use smooth scrolling box under it. This will enable the smooth scrolling feature.

And you are good to go! After enabling the feature, you can try and reconfigure the browser‘s settings to further optimize the smooth scrolling function.

To do this, go through the step-by-step guidelines below:

On the next window, enter general.smoothScroll.currentVelocityWeighting in the designated search box, and press Enter. Double-click on the entry from the list of results, and set its value to 0.

Set general.smoothScroll.mouseWheel.durationMaxMS to 250. Set genral.smoothScroll.stopDecelerationWeighting to 0.75. Lastly, you need to set mousewheel.min_line_scroll_amount to 28. And you are all set!

i hope it is helpful for you.

Hii

Okay, did some experimenting and found a setting in about:config that makes Smooth Scrolling both smooth and fast: look in about:config for mousewheel.min_line_scroll_amount. By default that has a value of 5. I changed that into 50 and now the Smooth Scrolling looks and feels like before.

Hope it would resolve your problem...
