Filter the Chrome console messages

You can negate filters by prepending with -. For example, -JQMIGRATE will exclude messages containing the string "JQMIGRATE".

Regex filters can also be negated this way. e.g. -/^DevTools/ will exclude messages that begin with "DevTools".

(Credit goes to Donald Duck, who suggested this in a comment on the chosen answer. I thought it was a far cleaner solution than negative lookaheads, and deserved to be elevated to a top-level answer.)

I think you can. Recent chrome versions allow filtering using regular expressions by enclosing the search pattern in /.../, previous versions had a checkbox. You can express, for instance, "not bar" by using negative lookaheads, as described here How to negate specific word in regex?

In the picture below, I tried filtering for "not bar".

I've found this to simple filter all console messages from extensions. This will also persist until you clear the filter. Type -chrome-extension:. This will REMOVE any messages that come from -> chrome-extension: <- urls.

You can use multiple filters by putting a space between each query. Ex. -chrome-extension: -cookie. Notice the space after the : and before the -c. This will REMOVE any messages that come from -> chrome-extension: <- urls and also REMOVE any messages with cookie in the context.

The accepted answer works for single line filtering, but I found it also filters out any multi-line logs. See the following examples.

No filter:

Accepted answer (missing multi-line logs):

Fixed negative filter (correctly keeps multi-line logs):

/^((.|\s)(?!Violation))+$/

Bonus! Easy filtering out multiple matches:

/^((.|\s)(?!Violation|creating))+$/
