准备工具/材料：装有windows10的电脑一台，火狐浏览器软件。
用火狐浏览器查看网页源代码的办法如下：
1、首先进入火狐浏览器浏览器首页，点击查看，如下图所示。
/iknow-pic.cdn.bcebos.com/72f082025aafa40f56a03d4fa564034f78f01939"target="_blank"title="点击查看大图"class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/72f082025aafa40f56a03d4fa564034f78f01939?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="
https://iknow-pic.cdn.bcebos.com/72f082025aafa40f56a03d4fa564034f78f01939"/>
2、在查看菜单下选择源。
/iknow-pic.cdn.bcebos.com/cf1b9d16fdfaaf514f92722d825494eef01f7a2b"target="_blank"title="点击查看大图"class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/cf1b9d16fdfaaf514f92722d825494eef01f7a2b?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="
https://iknow-pic.cdn.bcebos.com/cf1b9d16fdfaaf514f92722d825494eef01f7a2b"/>
3、打开源就看到本网页的源代码了，在最下方。
/iknow-pic.cdn.bcebos.com/55e736d12f2eb93834dc8960db628535e4dd6feb"target="_blank"title="点击查看大图"class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/55e736d12f2eb93834dc8960db628535e4dd6feb?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="
https://iknow-pic.cdn.bcebos.com/55e736d12f2eb93834dc8960db628535e4dd6feb"/>
4、还有一种快捷方法，直接按F12，可以进入调试程序，也是源代码。
