Sorry, kind of tech ignorant. This is one of the URL's...https://www.cabelas.com/shop/en/powerpro-braided-spectra-fiber-microfilament-line-300-yards but it happens on every stock check on the Cabela's website. I have been trying to save a screen shot but it doesn't seem to be working.

Here is what I see. see screenshot Did you try Firefox in Safe Mode? https://support.mozilla.org/en-US/kb/diagnose-firefox-issues-using-troubleshoot-mode

I did try safe mode and I refreshed firefox as well. On the page before your screen shot, there is the link to check availability. When I click on it I get a blank page with the word "safe" in small text in the upper left corner of the page. The page you posted is what I should be getting. It worked fine up until a month ago and it still works fine with all other browsers. Sorry, not sure where I came up with "safe", it actually says "true".

If you use extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) that can block content (Adblock Plus, NoScript, DuckDuckGo PE, 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
• https://support.mozilla.org/en-US/kb/troubleshoot-extensions-themes-to-fix-problems

Firefox shows a purple shield instead of a gray shield at the left end of the location/address bar in case Enhanced Tracking Protection is blocking content.

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

You can check the Web Console for relevant-looking messages about blocked content.

You can try these steps in case of issues with webpages:

You can reload webpage(s) and bypass the cache to refresh possibly outdated or corrupted files.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

"Remove the Cookies" for websites that cause problems:

• Settings -> Privacy & Security
  Cookies and Site Data: "Manage Data"

"Clear the Cache":

• Settings -> Privacy & Security
  Cookies and Site Data -> Clear Data -> [X] Cached Web Content -> Clear

• https://support.mozilla.org/en-US/kb/clear-cookies-and-site-data-firefox
• https://support.mozilla.org/en-US/kb/how-clear-firefox-cache

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 userChrome.css 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 Troubleshoot Mode start window

Thanks for the lengthy response. I tried everything you mentioned and still not working. I then did an uninstall / reinstall and it is still not working.

I'm seeing this Error message in all browsers- An error occurred while retrieving inventory status. Try again later. If the problem persists, contact your site administrator.

A store near my IP was autoselected. I'm thinking it's a Cabela's issue.

Does this work properly in other browsers?

I see the same blank page with only "true" if I click the "Check Store Availability" link, so this might be a problem with the script that is ru on the website. I've seen the "error occurred while retrieving inventory status..." message a few times, but it usually disappears if I reoload the page (F5) one or more times

All other browsers I've tried work fine. It is just the newest version of Firefox that is giving me the problems.

I see the same page with true in other Firefox versions I tried, so maybe the website recently made changes that cause issues with Firefox.

Thanks for your input. At least I know it isn't necessarily a problem on my end.
