I don't know whether the issue is related to cookies or not but one thing i am about is this browser is trash. Just some Microsoft engineers might find it better for development, i don't. My live server is immediately reflecting changes to my port 500 yet the browser is not. i have to manually refresh the page in order to see the changes, i have tried using about:config and network.http.use-cache and set the value to false, cleared all cookies and data several times to ensure the browser is not caching the old version of the page, but nothing works. i am done with this frustration. I am going to uninstall this legendary developer friendly piece of shit if you can't help me out here cause i can't bear to keep my fingers on ctrl+R every single moment in my life would rather press the uninstall button. the only reason i am keeping this browser is because some legendary developers suggest it . I have set the cookies and trackers block mode to standard. Now i don't know what is the issue, i might have wasted my data on downloading this browser but i won't hesitate to remove it from my computer. Hope you can understand frustration of a beginner developer, done with code already, now the browsers are screwing me as well.
