Thank you for this, @UlianaHolub!

I need a few days to test this locally because the Travis integration does not work anymore. After that I can merge and do a release.

Not sure if this is the right place to report this, but the first release that had this PR (3.141.59-20210729) started giving us service timeouts (using selenium-webdriver). Rolling back to 3.141.59-20210713 clears those up.

This commit is not related to the issue, it is a problem in Chrome 92.

There is an issue pinned on the issues tab, please have a look, a workaround is mentioned there.
