Hey. I'm doing site testing. On my Huawei P7 smartphone, the Firefox Focus browser did not cache the pages. That is, if I changed something in the CSS code, then after updating the page, the files with CSS were updated. Me this was very conveniently! Now I bought a Huawei Honor 9 phone and the program now saves the cache. I am updating the page and the CSS code remains old. Test sites no longer work. How do I disable caching ? Firefox Focus 4.0.2 (Build #20112247) on both smartphones
