Regain your privacy! Adopt /e/ the unGoogled mobile OS and online services
Try those steps:
1- delete history from classic menu inside the browser
2- clear all the storage from Settings->Site settings->storage
Thank u for Ur reply.
I forgot to tell the browser ‘delete always’.
Now everything is gone 
@Manoj
I see that u always edit my topics.
Sorry about that. Ill categorize my support topics as support now .
I ‘edit’ posts by moving them to correct category or by adding tags. Both of these make it relatively easier for other users to find it in future.
