It sounds like your protection programs are being overprotective. Try to disable them during the download.

If you mean Avast and the like, I don't have any. Can't run them.

Trying to allow a manufacturers' system scan after suffering longstanding desktop issues but before this can happen I have to download their support assist launcher. So the problem is, the download is blocked after the run/save window with another saying unknown publisher and so refuses to start downloading.

Firefox doesn't show "Run" in its download dialog. When do you see "Run"? The usual options are:

• Documents: Open / Save / Cancel
• Executable files: Save / Cancel

What is the link you're trying to download from?

I must have a foreign computer. A lot of the download stuff I encounter using Firefox says to click on save and then on the run buttons. Save places an icon in the download file, Run is supposed to open/install whatever it is from an unknown publisher. Anyway doesn't work in this case, but I keep trying to find an answer. Not important any more.

I had no problem with the download. Try just downloading the file. Is there still a problem?

On the Dell page, I see:

"Click on the downloaded file SupportAssistLauncher.exe located in the bottom or top of your browser window or in your Downloads (Ctrl+J)."

They are trying to cover all the different possible browser behaviors in just one sentence, so no wonder it is hard to follow! But that's probably better than sites that only give instructions for Chrome...

For me this is a normal every time download procedure in Firefox.

FredMcD Yes still a problem. I have 10 + icons in my download file due to trying different settings to allow unknown publisher material. Clicking on any one produces the Dell "problem with download" window suggesting I check my internet connection [generic message?]. Incidentally I've done a complete uninstall/install of Firefox via Google because it was behaving so badly and just wouldn't stabilize after a refresh. At least it's all ok now allbeit slow and prone to hanging if I browse on the one site for too long. Computer is quiet now also.

Note that there are browser.safebrowsing.downloads.* prefs available on the about:config page to allow/block specific unsafe downloads.

Options/Preferences -> Privacy & Security:Deceptive Content and Dangerous Software Protection

What engine did you use please, maybe my issue is a Google one.

Thanks but done all that without success.

Engine? I opened the website and downloaded the file.

So I guess this is one problem left in the unsolved basket. Any other download files I want present no difficulties just this one. Firefox is behaving beautifully at the moment since a uninstall/reinstall, only the occasional dreaded 'Firefox is not responding' window.

Thanks everyone for all the advise.

Hello,

I am glad to hear that your problem has been resolved. If you haven't already, please select the answer that solves the problem. This will help other users with similar problems find the solution more easily.

Thank you for contacting Mozilla Support.

Problem still exists. For whatever reason It's only the Dell site so I'll give them a miss. Telstra will switch on the NBN to our area later in the year? and then the server price of 'must buy it or get disconnected' will rise beyond my budget. But that doesn't help with my immediate download problem. So we'll just have to work around these little annoying Firefox demons, which I reckon is probably due in part to my aging desktop.

Make sure you are not blocking content.

Start Firefox in Safe Mode {web link} by holding down the <Shift> (Mac=Options) key, and then starting Firefox.

A small dialog should appear. Click Start In Safe Mode (not Refresh). Is the problem still there?

This download manager works separately from the browser. The browser tells it what to download, and off it goes.

http://www.freedownloadmanager.org It is a powerful modern download accelerator and organizer for Windows and Mac.

Thanks FredMcD but neither worked. Have ran in safe mode several times in past. http://www.freedownloadmanager.org/ Comes back with download Error on Dell supportassistlauncher.exe

There could be a problem with the Dell support. I called for more help.

Have you tried downloading using Win IE?

Win IE deceased, I would remove what's left but that removes Firefox as well. Done that eons ago. Luck with the phone call, Dell don't seem interested if it;s not warranty.

Go to another computer (public library for example) and download what you want to a thumb drive.
