Hey all - been trying to troubleshoot an issue with Firefox (multiple of the latest versions, but 77 currently) on Mac OSX Catalina, appreciate any help! '''Issue''': Certain websites intermittently display strange behavior, such as not loading interactive content (videos/gifs on reddit, for example, displaying as static images) and some sites not loading images at all (Twitter shows empty boxes where images would be) and a few other similar issues. '''Steps I've tried:''' - Using a private window solves almost all the issues. But disabling all extensions and plugins in a normal window doesn't solve it. (I believe I understand private windows to use the RAM for caching but use the HDD under normal circumstances?) - Enabling/disabling VPN makes no difference, nor does what network I'm on, and other devices on this network have no similar issues - Other browsers on the same computer have no issues - Malware, anti-virus, etc all are active and scan has been run a few times. - Apple's hardware diagnostic turns up no issues, and this has happened now in FF over multiple of the latest versions (not sure when exactly it started) on two different Macbooks, though the new one is from an image of the old one (maybe that's something?) - Uninstalling/reinstalling FF does not make a difference '''Where I'm at:''' The only thing that sort of worked (But it's now stopped working on certain sites, but continues to work for others) is moving FF's profile folder, uninstalling, and reinstalling. I was lead to believe FF would then create a new folder when this happened, but it just kicked up an error for me and wouldn't start. When I moved the old profile folder back and started up the freshly installed version with the old profile folder, the problems were all solved. Though as mentioned, they are starting to happen again on some of the sites. No errors or changes have been made that I can identify, plenty of space available on the HDD, etc. I've become a big fan of FF over the years (over Chrome), and want to stay in a privacy-focused browser, but I haven't been able to find much that seems to help this specific situation online. Any help is appreciated!
