Template use affects the generated HTML before it ever gets to the browser, so browser and version are irrelevant.

MediaWiki does place a limit on how many transclusions you can have on a page, whether you call a different template every time, call the same template over and over, or nest templates inside templates.

That limit is 300. It can be adjusted via config by staff, but don't count on it.
