Is Ezy Speed Test & Custom Web Search safe?

Low risk

Ezy Speed Test & Custom Web Search replaces the browser's default search engine with Yahoo search using embedded affiliate codes.

On install, the extension sets Yahoo as the default search engine via affiliate-tagged URLs (hspart=sz, hsimp=yhs-001) that route revenue from user searches to the developer. Both the browser search bar and the extension's own in-page search use these affiliate identifiers. The extension description mentions 'Custom Web Search' but does not disclose the affiliate monetization arrangement.
