Three essential tweaks for FireFox

The following tweaks work for all Mozilla based browsers such as FireFox, Light, WaterFox, Pale Moon and etc.

RememberPass add-on

This add-on forces FireFox to remember passwords for sites that do not want you to.

Toggle animated GIFs

Not only very annoying and distracting, animated images also consume computer resources (i.e. slow down), run them hot and drain your laptop's battery. With this add-on, you can make them quiet by default and, when you do want to see the action, click on them to play.

For Flash, you can, and you should, make the plugin to always "Ask to Activate":

UserContent.css

There are two more annoying things to block: scrolling (marquee) and blinking text. Find the profile directory (e.g., Palemoon\User\Palemoon\Profiles\Default) and create a new folder "chrome". Within this new folder, create a new file "UserContent.css" and copy and paste these two lines into it:

marquee { -moz-binding: none; }
blink { text-decoration: none ! important; }

Then restart your browser. Don't worry, you can still see the text in full, just not scrolling nor blinking, nice, ha.

All above methods has no side effects like ad and flash block add-on while making your browsing experience entirely calm.
