Browser is a web testing library for Robot Framework that utilizes the Playwright tool internally. Browser library 19.12.6 is a new hotfix release with fixes to supporting large responses from NodeJS side to Python side, timeout argument was added to gRPC messaging when browser and context was closed, @yao-pkg/pkg reference was fixed and run on failure was not always called when keyword failed. There are also formatting changes to NodeJS side, caused by using the Eslint latest major release and fixing the linting errors (which should not affect users of the library.) All issues targeted for Browser library v19.12.6 can be found from the issue tracker. Browser library 19.12.6 was released on Wednesday March 18, 2026. Browser supports Python 3.10+, Node 20/22/24 LTS and Robot Framework 6.1+. Library was tested with Playwright 1.58.2.
