Hello Idm is not working with Mozilla Firefox It is perhaps due to update By the way I often use Google chrome, though Firefox is my default browser and I made search engine Google, because other search engine options do not support me in Google books It is also another thing I noticed in chrome : [ your setting is managed by your organization] - this is of course is unusual feature and maybe a malicious thread infected Google policy which I lately solved. It is perhaps my Mozilla browser being affected as well. I see it looks better now. I solved

Thanks
