- [How to install an extension](https://merca.getchrovia.com/en/docs/install-extension/index.md): Install Chrome Web Store or unpacked extensions in a Merca store window. Each store keeps its own extensions for the next browser launch.
- [How to manage local store data](https://merca.getchrovia.com/en/docs/store-data/index.md): Change the local data directory on this computer, or clear cache and local data. This does not delete stores on the account.

- [Which country should I buy a node in](https://merca.getchrovia.com/en/docs/node-country/index.md): Choose a dedicated static ISP IP for your store, or a lower-cost datacenter IP. Pick Hong Kong, the US, or a local IP based on the store's registration details and platform.
- [Can one node run stores on different platforms](https://merca.getchrovia.com/en/docs/node-platforms/index.md): Yes. One node can run one Amazon store, one TikTok Shop, and one Walmart store. A second login on the same platform is blocked by default.
- [Is it risky to change a store's node](https://merca.getchrovia.com/en/docs/change-node/index.md): It depends. Stay in the same country when you can. Don't switch often in the first months of a new store.
- [What is node contamination](https://merca.getchrovia.com/en/docs/node-contamination/index.md): Learn why a proxy IP's past use cannot be fully verified, what node contamination means, and where to find Merca's node setup and cancellation guides.

- [Will a broken system proxy expose the local network](https://merca.getchrovia.com/en/docs/proxy-chain-exposure/index.md): No. If the local proxy fails, the store window still uses the node. It does not fall back to this computer's broadband.

- [Should I sign in to email in Merca?](https://merca.getchrovia.com/en/docs/email-login/index.md): Open store email and platform links in the matching Merca store window, so they use that store's node and fingerprint settings.
