| // ADDING NEW EXTENSIONS REQUIRES APPROVAL from Extensions Tech Lead: |
| // rdevlin.cronin@chromium.org |
| // |
| // The main acceptable use of extensions in the default Chrome experience (i.e. |
| // not installed explicitly by the user) are to implement things like the |
| // history or settings pages. These are things that look like web pages, load |
| // in response to explicit user action, and use no resources when not opened. |
| // |
| // If you are asking for approval to add a new built-in extension to Chrome |
| // (whether downloaded with the binary or downloaded later on-demand), check: |
| // |
| // - It must not do anything on startup. Loading extensions processes on |
| // startup can significantly slow things down. |
| // |
| // - It must not have a background page. Extension processes use a nontrivial |
| // amount of memory that makes them inappropriate for built-in features. |
| // |
| // - Avoid event pages. Some events such as navigation will be even worse than |
| // background pages since it will cause the extension to be frequently |
| // loaded and unloaded. Even if your event page is "good" now, it's |
| // something that is easy to regress with inocuous looking changes, so |
| // try to use explicit C++ invocation of the extension when reasonable. |
