For each supported browser there is a wrapper script that launches `curl-impersonate` with all the needed headers and flags. For example:
```
curl_chrome99 https://www.wikipedia.org
curl_chrome101 https://www.wikipedia.org
```
You can add command line flags and they will be passed on to curl. However, some flags change curl's TLS signature which may cause it to be detected.

### Using CURL_IMPERSONATE env var
*Experimental*: If your application uses `libcurl` already, you can replace the existing library at runtime with `LD_PRELOAD` (Linux only). You can then set the `CURL_IMPERSONATE` env var. For example:
```bash
LD_PRELOAD=/path/to/libcurl-impersonate.so CURL_IMPERSONATE=chrome98 my_app
LD_PRELOAD=/path/to/libcurl-impersonate.so CURL_IMPERSONATE=chrome101 my_app
```
The `CURL_IMPERSONATE` env var has two effects:
* `curl_easy_impersonate()` is called automatically for any new curl handle created by `curl_easy_init()`.

* [curl_ff91esr](firefox/curl_ff91esr), [curl_ff95](firefox/curl_ff95), [curl_ff98](firefox/curl_ff98) - Wrapper scripts that launch `curl-impersonate` with the correct flags.
* [curl-impersonate.patch](firefox/patches/curl-impersonate.patch) - The main patch that makes curl use the same TLS extensions as Firefox. Also makes curl compile statically with libnghttp2 and libnss.
