I have been building websites using Firefox for a good 10 years now, but over the last year or so clearing the cache has become more and more frustrating and it's making Firefox unusable for developing websites. Basically, I am making edits to a website's style sheet and uploading it and the new style sheet is not then being loaded in Firefox. I have spent the last hour+ looking for a definitive answer to this problem. I am using both methods I know for clearing cache 1) click on the burger and go to Privacy and Security / go to cookies and site data / click clear data / leave "cached web content" clicked on (switch off "Cookies and Site data") / click clear 2) hold command / shift / R Most of the time it seems both these methods don't seem to work as the browser won't load the new style sheet. I know the style sheet has uploaded as when I test the site in Safari (I might have to use the Empty Caches function once) and the new style sheet loads straight away. I don't know what I'm doing wrong, or may be I am missing something fundamental that will cure this problem - all I can say is, it is very, very, very annoying - and really wastes time when you're trying to work. Is anyone else getting these problems and is there a quick and easy way to be ensuring the cached css file does not keep loading. btw I also used a private window and was still getting the same problem. I like using Firefox and don't really want to use another browser as they are rubbish in other ways, but feel like I'm getting to a point where I have no option if I don't find out how to solve this problem. Any help will be greatly appreciated. Regards D
