Every time I start up firefox, it takes about a full minute to load. It shows an outline of the UI, but does not become usable for a while, windows also puts up a "firefox is not responding" window when the window is interacted with. After loading, opening a new window is unaffected, and page loading is snappy. just the initial launch is the issue. This remains true even after a clean uninstall + reinstall. Appdata folder was removed as well, and did not affect the issue. I do not have any antivirus software other than windows defender, so that should not be an issue. My hardware is also not likely to be at fault, as it is sufficiently up to date (upgraded within last year, not sharing specs here). Chrome starts up in less than a second for reference. Once again, a fresh install with a new profile has the same symptoms. Have tried every available guide to no effect.
