Hi Kevin, this popup doesn't actually require an exception because it is generated directly after you click a menu item on the site. So it is strange that you don't get that window

If JavaScript was completely disabled, after you click the menu item, a # would be added to the URL in the address bar. I don't see that in your screenshot, so it's probably not an issue with scripts being blocked.

Could you open the Web Console in the tab with the main page, using Ctrl+Shift+K. You can click the trash can icon at the upper left to clear the existing messages. Then, after trying the menu item again, do any new messages appear in the console?

@jscher2000 - I tested that theory about the JavaScript. After I do click the Foxit Account it does append an # to the end of the URL. Based on your response I take it JavaScript is disabled. Is there a way to add an exception for that so JavaScript can run on this site?

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

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

Troubleshoot Mode did not work. The site still does not function when using that mode. I believe @jscher2000 was on the right track.

If JavaScript was completely disabled, after you click the menu item, a # would be added to the URL in the address bar. I don't see that in your screenshot, so it's probably not an issue with scripts being blocked.

Why would JavaScript be disabled for this site though? I checked the about:config in the address bar and the preference javascript.enabled equals True.

If it helps, I followed @jscher2000 steps about Ctrl-Shift-K and attached are its messages.

This works for me with browser.link.open_newwindow.restriction set to 2 (diverted to popup window) and with set to 0 (diverted to a new tab) and it issues openLoginWindow() Is this function defined if you paste openLoginWindow in the Web Console?

• function openLoginWindow(from, force)

Boot the computer into Windows Safe Mode with network support to see if that has effect in case security software is blocking this popup.

• https://www.bleepingcomputer.com/tuto.../how-to-start-windows-in-safe-mode/
• https://www.digitalcitizen.life/4-ways-boot-safe-mode-windows-10/

I set the browser.link.open_newwindow.restriction to 0 it was set to 2. When I search for openLoginWindow the value for that is True. But the log in screen still does not open in the new tab. I am not sure what you mean by

Is this function defined if you paste openLoginWindow in the Web Console?

• function openLoginWindow(from, force)

I probably should also mention that safe mode did not work since you mentioned that too.

That second screenshot shows about:config. You need to check in the Web Console to is if openLoginWindow is defined.

• "3-bar" menu button -> Web Developer or Tools -> Browser Tools -> Web Developer Tools
• https://firefox-source-docs.mozilla.org/devtools-user/web_console/

If I did this right, then it is not defined.

You need to enter this in the command-line in the web console and not in the search/filter bar.

• https://firefox-source-docs.mozilla.org/devtools-user/web_console/ui_tour/

Oh okay. Typing it there produces.

ReferenceError: openLoginWindow is not defined

Am I able to define it myself or is that an issue with the website?

This means that the JavaScript that defines and handles this function is blocked.

Do you at least get a drop down panel with the choices if you hover the Login button ?

You can check the Network Monitor to see if content is blocked or otherwise fails to load.

• https://firefox-source-docs.mozilla.org/devtools-user/network_monitor/

If necessary use "Ctrl+F5" or "Ctrl+Shift+R" (Mac: Command+Shift+R) to reload the page and bypass the cache to generate a fresh log.

I do get the drop down of panel choices when hooving over Log In. How can I unblock JavaScript for this page?

Sorry, I just noticed that the # appears on the address bar even when the popup window for signing in opens successfully, so that isn't as much of a tell as I thought before. (Screenshot attached.)

Did the site lose permission to open popup windows? You can check using the Page Info dialog while you're on the site. Here's how:

• Press Ctrl+i to open the Page Info dialog
• Click Permission to switch panels
• Scroll down to "Open pop-up windows"
• Uncheck "Use default" and select Allow

More generally, I only got it to fail a couple times, after which reloading it made it work. So I don't know what is causing the problem.

Sadly that already showed it was select to Allow. I even tried changing to Default then back again to Allow which didn't work either. I admit this is one weird issue I got going on.

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

• https://support.mozilla.org/en-US/kb/troubleshoot-extensions-themes-to-fix-problems

You can create a new profile as a quick test to see if your current profile is causing the problem.

See "Creating a profile":

• https://support.mozilla.org/en-US/kb/profile-manager-create-remove-switch-firefox-profiles

If the new profile works, you can transfer files from a previously used profile to the new profile, but be careful not to copy corrupted files to avoid carrying over problems.
