some more info on this problem. It will not work with internet explorer I am using windows 7 32 bit It works on a notebook running win 7 64 bit. It works on another PC running win 10 64 bit. I have disabled all add ons, cleared cache, disabled Nortons, cleared bookmarks. As this program runs from the Fronius site there would appear to be nothing stored on my PC that I can remove and reinstall. After clearing the cache it asks for my login details which it appears to accept but does not run the program, it just goes back to the home page. When I go to log on from the home page it does not ask for my password but goes to a redirect message then back to the home page. This has become annoying as I like to use Firefox not Chrome.

This site also no longer works with Firefox. https://yamahagroup.sharepoint.com/sites/YSISSMGS/SitePages/Home.aspx It was working until late October The same as the Fronius site it asks for my password then says it cannot log me in. It works on Chrome and also on my notebook with Firefox.

Obviously no one is listening, but you can add another site to the list. www.laptopjacks.com Same as above. Lets hope your next upgrade fixes these problems, (or not).

This can happen if you block cookies.

If you use extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) that can block content (Adblock Plus, NoScript, Disconnect, Ghostery, Privacy Badger, uBlock Origin) always make sure such extensions do not block content.

• make sure your extensions and filters are updated to the latest version

Firefox shows an highlighted shield icon at the left end of the location/address bar in case Tracking Protection is blocking content.

• click the shield icon for more details and possibly disable the protection

You can check in the Web Console what content is blocked.

• "3-bar" menu button or Tools -> Web Developer

You can try these steps in case of issues with web pages:

You can reload web page(s) and bypass the cache to refresh possibly outdated or corrupted files.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

Clear the Cache and remove the Cookies for websites that cause problems via the "3-bar" Firefox menu button (Options/Preferences).

"Remove the Cookies" for websites that cause problems:

• • Options/Preferences -> Privacy & Security
    Cookies and Site Data: "Manage Data"

"Clear the Cache":

• Options/Preferences -> Privacy & Security
  Cookies and Site Data -> Clear Data -> Cached Web Content: Clear

Start Firefox in Safe Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration is causing the problem.

• switch to the DEFAULT theme: "3-bar" menu button or Tools -> Add-ons -> Themes
• do NOT click the "Refresh Firefox" button on the Safe Mode start window
