Actually Buttons like More, Web Developer, help, etc are not working. Click on Right side sliding is also not working. Sliding that shows on google review is also not working and same issue is on all other websites. And when firefox open I wait for long time for webpage display. Sometimes click on weblinks the immediate response is not occur by the firefox. All its old versions of firefox are good, But this version has many faults. On this page during posting this problem when i click on "Browse" image, Cancel and All Supported types dropdown buttons are not working.
