If a translation extension works on public websites but stays inactive on internal portals or finance tools, organization policy may be blocking extension interaction on those hosts. That is different from a broken install or a store outage.
Chrome ExtensionSettings Runtime Host Rules
Chrome Enterprise documentation describes `runtime_blocked_hosts` as a way to prevent extensions from interacting with or modifying websites you specify, including blocking JavaScript injection, cookie access, and web-request modifications. `runtime_allowed_hosts` can grant interaction for specific hosts even when they also appear in blocked lists.
The same documentation states you can specify up to 100 host-pattern entries per list, and additional entries are discarded. For documentation authors, this is a useful detail: enterprises protect a small set of high-value domains first, rather than chasing every subdomain ad hoc.
Not the same as uninstalling the extension Runtime host rules operate at the site layer. The extension may still be installed and visible, but it cannot behave normally on domains covered by blocked host patterns.
Edge Enterprise Guidance on Runtime Host Controls
Microsoft Learn’s enterprise extension management article highlights “Runtime block hosts” as a control to define which websites extensions can access and to protect the most sensitive internal sites. The goal matches the Chrome model: reduce data exposure without pretending extensions are risk-free everywhere.
How Users Can Tell Policy from Product Issues
Step 1: test the same extension on a personal device. If it works there but not on a work device, suspect management policy. Step 2: test a simple public page. If public pages translate but internal apps do not, runtime host restrictions are a plausible explanation. Step 3: look for enterprise management indicators in the browser. Step 4: share the hostname and error UI with IT and ask whether ExtensionSettings or Edge host controls are applied.
Avoid unknown CRX mirrors when policy blocks interaction; the underlying restriction will still apply. When policy permits, follow the verified route on the download and setup page for personal devices.
