Hi, I'm using FF for year for development and had several problems with cached data in this time. Now, since the last update (automatic update yesterday), Firefox is caching my js for localhost and ignores nearly everything to stop it. F5 and Ctrl+F5: no effect Enabling "Disable cache" in devtools: no effect changed about:config (no effect): browser.cache.disk.capacity 0 browser.cache.disk.enable false browser.cache.memory.enable false devtools.cache.disabled true Only going to '''settings > privacy + security > Clear Data ''' helps. But as you can imagine, that's really bad DX I tried a FF-addon for clearing css cache, but it's outdated and doesn't work. Is there anything I can do, to disable cache for localhost? I don't understand why this aggressive caching problem is ignored for years and gets worse every year! Why are settings like "Disable cache" in devtools so broken? I tested other browsers and have not found the same issues. I don't want to switch browsers! I just want a cache free localhost! FF can cache the sh*t out of every webpage. But please leave localhost out of it!
