My Testing Thoughts

Almost a month back, we discussed how we can install an extension in Selenium 3: https://www.linkedin.com/posts/dheerajgambhir_seleniumautomation-chromeext-automationtesting-activity-6587948591678095361-Lr7m Or https://testersdigest.blogspot.com/2019/10/need-extension-while-running-your-se.html And now in Selenium 4, we have direct method installExtension and uninstallExtension for the firefox Driver.
