Firefox About:Config Tweaks

[HarleyQuinn]

Since I like tweaking things and thought it'd be good to have an about:config thread for people who want to speed up Firefox and can't/won't use Google Chrome. As always, backup the settings before starting and write down what you change/what the original was.

Open Search Results In New Tab
browser.search.openintab = True

To Speed Up Image Loading
image.cache.timeweight = 1000 (instead of 50000)

To Speed Up Font Loading Time
gfx.font_loader.delay = 5000 (instead of 120000)
gfx.font_loader.interval = 100 (instead of 500)

To Speed Up Scrolling With Mouse
mousewheel.acceleration.factor = 18 - Play around with this for personal preference. You can go higher if you want, I liked it at 18.
mousewheel.acceleration.start = 1
mousewheel.min_line_scroll_amount = 40 - Play around with this for personal preference. Lower if you want slower, higher if you want faster.

To Disable the Wait When Installing Add-Ons
security.dialog_enable_delay = 0 instead of 1000

Enable Images to Automatically Show Full Size in New Tabs vs. Fitting to Screen
browser.enable_automatic_image_resizing = false (instead of true)

Change How Many Popups Appear on Screen at Once (good for if you don't have a popup blocker/get malware/adware)
dom.popup_maximum = 3 (instead of 20)
