Real Downloader button missing in Firefox 57 Quantum
I have been using Real Downloader in previous versions of Firefox, but now with Firefox 57 the Downloader button at the top of the screen is missing. Downloader is not present in either Extensions or Add-ons.

See if you can find updates for your Intel(R) HD Graphics 4600 as they are a yr old : driverDate: 9-29-2016 You can Google Intel(R) HD Graphics 4600 and find the download page https://downloadcenter.intel.com/product/81496/Intel-HD-Graphics-4600, but you may have to know what generation chipset you are using. CPU-Z would tell you this https://www.cpuid.com/ Can also try : https://www.intel.com/content/www/us/en/support/detect.html I do not see any errors in the drivers. Old & corrupted Drivers cause a wide range of issues. Please keep them updated to prevent issues and you never know when Intel will stop supporting them.
Please let us know if this solved your issue or if need further assistance.
