Issue with Firefox 102 (64), Reddit and AdBlocker Ultimate
Since this most recent version of Firefox (102) upgraded my software on Jun 28, the Reddit website has not loaded correctly. All it displays is a blank page. Ad Blocker Ultimate registers about 1 ad blocked per second. This is the only site I've had this issue with. This all worked (as expected) prior to Jun 28.

If you use Ghostery then this might be a problem with the Ghostery extension as we recently have seen more reports with issues accessing Reddit.
If it is your ad blocker rather than Ghostery, try clearing its cache and updating it.
