Is your IT likely to be helpful with this issue? If not...

Is it a common platform that has a tech support site, or something very custom that you'll need to troubleshoot on your own?

If you're on your own, could you check for error messages in the Browser Console. To call that up, either:

• Ctrl+Shift+j
• menu button > Web Developer > Browser Console
• (menu bar) Tools > Web Developer > Browser Console

Click the "trash can" icon in the upper left corner to clear current messages in the console.

Switch back to your intranet page and reload it (Ctrl+r). Check the console for errors but ignore the blue warning triangles for style rule problems. Anything that looks serious?

Clear the console again, then in the intranet page, try the Excel export command. Any new error messages?

Thank you fir your response. Unfortunately my IT only supports IE. I tried your suggestion and a few errors appeared, however, they appeared before I clicked the excel button. I tried it a few times and different errors appeared but none after I hit the excel button.

Do you want to mention what the error messages are?

Also, when you hover over the Excel export command, does Firefox show a URL in the lower left corner like a regular link? If so, does it show a different page address or does it show something that is meant to be replaced by a script, such as "javascript:void(0);" or other nonsense. If you see a different page address, try using right-click > Open Link in New Tab to see whether that makes any difference.

I gave up on using FireFox for awhile, I was getting frustrated with it, however, others in my field use it and state it has quicker response times to loading the data tables. I seem to be the only one using Windows 10. Not sure if this may be the issue as to why I can not export or copy the files. Let me know if you can assist. There are no links when I hover over the excel export command (there are no links either in IE). This is the errors I see in the browser console: Using //@ to indicate sourceMappingURL pragmas is deprecated. Use //# instead jquery.min.js:1 downloadable font: download failed (font-family: "Raleway" style:normal weight:normal stretch:normal src index:2): status=2152398850 source: https://fonts.gstatic.com/s/raleway/v12/1Ptug8zYS_SKggPNyC0ITw.woff2 unknown:10:11 ReferenceError: getEnvUrl is not defined

Hi HBeer, thanks for the error messages.

"Deprecated" is a warning for the site developer. The inability to download a particular font doesn't really sound like it should be a problem for downloading. So that leaves one:

ReferenceError: getEnvUrl is not defined

It sounds important, but out of context, it isn't meaningful to me...

Could you make sure pop-up windows are allowed for the page? You can set that using the Permissions panel of the Page Info dialog.

While you are on that page, you can call that up using any of these:

• right-click a blank area of the page and choose View Page Info > Permissions
• (menu bar) Tools menu > Page Info > Permissions
• click the padlock or "i" icon to the left of the site address, then the ">" icon, then More Information > Permissions

Scroll down to "Open Pop-up Windows" and uncheck the "Use default" box, and then click the bubble for Allow. There's no Save button to click, the change should be saved immediately in the background, so you can close Page Info after that.

Any improvement?

If you haven't already, could you test in Firefox's Safe Mode? In its Safe Mode, Firefox temporarily deactivates extensions, hardware acceleration, and some other advanced features to help you assess whether these are causing the problem.

If Firefox is not running: Hold down the Shift key when starting Firefox.

If Firefox is running: You can restart Firefox in Safe Mode using either:

• "3-bar" menu button > "?" button > Restart with Add-ons Disabled
• Help menu > Restart with Add-ons Disabled

and OK the restart.

Both scenarios: A small dialog should appear. Click "Start in Safe Mode" (not Refresh).

Any improvement?

We also are seeing more issues with content blocked by Firefox's Tracking Protection feature. When that is in effect, a "shield" icon will appear at the left end of the address bar near the "i-in-a-circle" or padlock. This article has more information on managing the feature: What happened to Tracking Protection?.

Thanks again for your help. The pop up blocker was on, I clicked allowed. No improvement. I tried it in safe mode, no improvement. There is no shield icon in/near the address bar.

Could you check for a connection error in Firefox's Network Monitor? In the lower part of the tab, open the Network Monitor using either:

• (Windows) Ctrl+Shift+e
• "3-bar" menu button > Web Developer > Network
• (menu bar) Tools > Web Developer > Network

Then click the button to get the CSV file. If Firefox sends a request to the server, that should appear on the network list. If it does, what status does the server report? For example, 200 for success, 301 or 302 for a redirect, 400+ for authentication error, 500+ for internal server error.

If Firefox doesn't even request the CSV, and you know this button works for other Firefox users, perhaps there is some setting we're not thinking of. To test Firefox without stored settings, you can try:

New Profile Test

This takes about 3 minutes, plus the time to test your site.

Inside Firefox, type or paste about:profiles in the address bar and press Enter/Return to load it.

Click the Create a New Profile button, then click Next. Assign a name like April2018, ignore the option to relocate the profile folder, and click the Finish button.

After creating the profile, scroll down to it and click the Set as default profile button below that profile, then scroll back up and click the Restart normally button. (There are some other buttons, but please ignore them.)

Firefox should exit and then start up using the new profile, which will just look brand new. Skip over any suggestions to activate extensions or sync data to keep it clean.

Does the site work any better in the new profile?

When you are done with the experiment, open the about:profiles page again, click the Set as default profile button for your normal profile, then click the Restart normally button to get back to it.

When I clicked the button, it did not show anything in the network monitor. I created a new profile and signed back in and it still will not export the file.

Others have no problem using firefox, the only difference is they are using Windows 8 and I have Windows 10.

I can't think of a reason for Firefox to work differently on Windows 10 compared with Windows 8, especially in a managed environment where you probably all use the same security software and other programs.

You can change your Firefox shortcut to run in a "compatibility" mode which emulates Windows 8. This changes how Windows responds to Firefox, the version it reports to Firefox, and could slightly affect your Firefox toolbar area appearance. What I'm curious about is whether it affects how the page works.

If you want to try it, find the icon you use the start Firefox, and either:

• Right-click a desktop shortcut, then click Properties
• Right-click a Firefox icon pinned to the Taskbar then right-click Mozilla Firefox, then click Properties

On the Compatibility tab, check the box that lets you select the earlier Windows version to emulate, and try Windows 8.1 or 8.0. That should take effect the next time you start Firefox.

I changed it to Windows 8 and no change. I even tried 7 and still no luck. Thanks again for your help.
