Anyone seeing the following problem this morning:
- on the the laptop I'm using to post this thread, I'm not having any issues with FF
- however, on another laptop (downstairs) I got invalid site-certificate messages for both this site and at least 1 other (totally unrelated) one, whereas I didn't get those messages last night.

Therefore has FF been updated overnight, and maybe the problem machine got it first?
 
Were both left switched on overnight?

No - both were switched off, as were the modem & router.

PS: sorry for the delayed response - starting to trim the front hedges, and inadvertently cut throuh the broadband coax! :-doh Now fixed, obviously.
 
35 mins later, I found that the small laptop that threw the FF certifcates message has stopped doing that - but, like IE11, I also found that I can't now reply to Threads!

At that point FF auto-updated to V 60.0.1 but that made no difference.

On the main laptop that didn't throw the certificates message early on, that has now also updated to FF V 60.0.1 but I can post and reply to messageso_O
 
60.0.1 here, working fine on Win 10 Tablet.
 
Just updated FF here, initially it broke the forum (nothing loading, just a spinny icon thing), but closing & reopening the tab seemed to sort it no certificate issues though...
 
Update: FF on the small laptop seems to have fixed itself - I did nothing except "walk away" for a couple of hours :confused
 
All working fine here with the new FF update, on all machines....I have found that the time/date on the PC can change after an update to the OS, don't ask me why, but it affects the security stuff.

And Jeallen01, you have computer Gremlins, you need to leave a small shot glass half full of scotch and a nice biscuit on the fireplace mantle, this will keep them happy.

Changes in PC dates/times not seen here so far.
As for "my" gremlins, 2cvbloke had some issues as well (see above) - and it would bourbon/Irish or Ouzo (if I had any ATM!) that I would leave on the mantle as I prefer those to Scotch :D
