Albert I have the Logitech MX1000 and simply rolling the wheel moves the window up or down. If I press down first then roll the wheel it does change the font size. I should change that because before I had it set so that when I pressed the wheel I could then move the mouse down slightly, release it and the page would continue to scroll. Setting at the speed of reading avoided constantly moving the page with the mouse.

Imported from another thread. Interesting event just now this morning. Through the FF release channel it was reported an update was available for my system; specifically v12. I figured what the heck because it would be just busy work if there is indeed a problem with the new version. Well, my system failed to connect to the download site and it was recommended I retry. I did with still no success. I then closed FF and tried once more. The release channel updater reported that my FF 11 was the current version. I am returning to my prior wait and see position. DA

I also use "no squint" and it's great. You can adjust size and color of the text or the size of everything on the monitor. It will also change the colors of the background from that bright white. It really helps with eye strain.
