Is this at one site, several, most? Can you post a link to one of the problem pages? What were you trying to save and how?

I am downloading image files (png, jpeg/jpg, gif), I right click on the image and choose "Save Image As..." It is several sites, many different ones and sometimes an image will work and sometimes it won't, I visit it one day and it won't work, I'll save the link as a bookmark or in a .txt file, try tomorrow and then it'll work. Or I'll copy the link into another browser and it works fine even if its the same day and it won't work in Firefox but it'll work in Chrome.

Unfortunately can't post a link to one that doesn't work because as I said it'll not work one day and then work another and it occurs at random intervals.

I only have this problem in Firefox so it leads me to believe that the browser is the problem, not the sites I'm on.

Give this a try; the next time you try to save and it fails, hold down the shift key and refresh the web page. Then try again.

Pressing shift while clicking refresh seems to have worked, thanks FredMcD.

Still I have to check to make sure each image downloaded to see whether or not it worked which slows me down, Mozilla should look into this. But I appreciate the solution.

You can reload web page(s) and bypass the cache to refresh possibly outdated or corrupted files.

• Hold down the Shift key and left-click the Reload button
• Press "Ctrl + F5" or press "Ctrl + Shift + R" (Windows,Linux)
• Press "Command + Shift + R" (Mac)
