Recommended AddOns and Mods

Add-Ons are awesome. They allow for players, developers and members of the ESO community to make and share useful tools which can enhance your ESO experience, make life a little easier, automate some mundane tasks and display a lot of useful information, stats and resources.
Add-Ons themselves are not made by ZOS, the developers of the Elder Scrolls Online, but are made by other people, most often other players. ZOS allows the use of Add-Ons and supplies the API which developers can use to make Add-Ons. Add-Ons are only available to PC players and at this time no plans are in place to allow Add-Ons on the console version of ESO. The API that ZOS provides is designed to allow the use of convenience and display Add-Ons but not performance enhancing or “cheat” Add-Ons so that players without Add-Ons can still compete.

How to install Elder Scrolls Online add-ons
Start by navigating to My Documents\Elder Scrolls Online\live. You'll see an Add-Ons folder—unsurprisingly, you drop add-ons (in their own folders) into the Add-Ons folder. When you run ESO, there's a convenient menu called Add-Ons, and anything you've added to the folder should be enabled automatically. Just keep in mind every variant of the word "add-on" and you're golden.
You can manage all your add-ons and tools from the special Management screen. It’s easy to find it: go to character select screen and find “Add-Ons” button in the upper left side (under “Options” button).
The screen allows users to enable, disable and remove installed tools. There is also a special filter that allows the management of add-ons for all characters or for a specific character. This allows users to create custom tool sets for different classes and play-types. It’s a comfortable solution. For example you can enable Alchemist tool for your Sorcerer only and other characters will not be able to use it.

Useful Add-Ons
There are a lot of Add-Ons available and they can perform a number of different functions. It is important to remember that some Add-Ons can harm your game performance in certain situations. If you are having performance problems you should first try to disable your Add-Ons to check if they are causing the problem. Here are some of the best Add-Ons and their functions.
