If you perform any query in extension it automatically adds an entry to browser history.
I search a lot and extension is spamming browser history with queries, filters resulting in increase in firefox DB size, slow browser performance.
Weirdly it adds an entry for each letter in query to browser history.
If I search for a keyword memex it adds 5 entries to browser history.
extension-id/options.html#/overview?query=m
extension-id/options.html#/overview?query=me
extension-id/options.html#/overview?query=mem
extension-id/options.html#/overview?query=meme
extension-id/options.html#/overview?query=memex
With filters:
/options.html#/overview?query=memex&tagsInc=tagname
