Safari Favicons disappearing

Since my update to the latest Safari (recently, in the last fortnight or so), I keep loosing all my favicons (Version 18.5 (19621.2.5.18.1, 19621). I see from the forums that this is a common problem. I’ve cleared my favicons cache in the library five times now; and sometimes, when I reload tabs the favicons return. A day later, they are gone again. It’s driving me nuts - I am realizing now that I commonly navigate my bookmarks by the pictures as much as the name of the website.

Is anyone else having this trouble, and/or found a permanent solution?

I am nearly ready to trade browsers, perhaps back to Chrome or Firefox, but I’d prefer to stay on Safari if I can fix this permanently.

I never notice favicons, but others reported the problem a year ago.

I’ve had this happen to on both iPhone and iPad. It must be a common bug.
