On F/fox its just as it has always been, but when I go on Google chrome when f/f is playing up, its different in many ways?
The format is different, dosent have certain colours, like the yellow of the posters, no red colour for the Q in threads to the right, peoples photo/name, or my subscribed post, and no boxes around most?
Try this:
If in Chrome click on the three dots or bars at the extreme right of the address bar.
Scroll down and click on History.
Click on Clear History.
A menu will appear. Make sure only the top two items are ticked.
This should clear your browsing history whilst keeping your passwords.
