I can't even click on the open. Click tools, downloads, right click item but won't highlight open word. Also I can't restore computer to any earlier date. Yesterday I tried to to install samsung kies to work with my S-3 phone. When I click on that is says it had corrupted files. . I then restored mozilla. Nothing. I didn't lose any thing like history, browser history, cookies. Still nothing. Then later yesterday trying to follow so steps from mozilla I lost everything in history, browser history, cookies. I noticed I have on the desktop a old firefox data 2 folder with stuff in it. Tried to restore in safe mode and click on the downloads. No luck. Thought let me upgrade mozilla. Can't open download. And everytime I do download it says cancel first then I have to retry. Not sure if this samsung kies has anything to do with it. When to add remove programs and its not there. But it did download and 2 icons on desktop. Can't delete that program......
Everything looks ok there. I was hoping to restore to earlier date to solve this but why can't I do that? Seems to be the big issue also.
If "Open" and "Open Containing Folder" in the right-click context menu in the Download Manager window are grayed then that means that the file is no longer in the original download location and they may have been removed by Anti-virus or cleanup software.
It is possible that anti-virus software is corrupting downloaded files or is otherwise interfering with downloading files.
Try to disable the real-time (live) scanning of files in your anti-virus software temporarily to see if that makes downloading work.
I went through a few things as you ad sent and changed my security for internet. Then was able to see the black to open a download. Oh with that. So far so good. Didn't try the restore stuff. Now tried to download a rebate form and got a plugin screen to upgrade these. I clicked ok and went to mozilla clicked ok and then nothing. never loaded. Now Go back on tools, download can't right click on grayed out......
