Hi, my first suggestion would have been Safe Mode, but it seems you've tried that. So try deleting ALL references to Washington Post. To do that, open the 3-bar menu, choose History (looks like a clock), then click the Show All History link at the bottom of the list to open the Library window. Search for Washington Post by typing it into the Search History field in the top-right corner, then press Enter. Now in the search results, right-click on it, and select Forget About This Site. (Browsing and download history, cookies, cache, active logins, passwords, saved form data, exceptions for cookies, images and pop-ups for that site will be removed). Give it a minute to complete the deletion, then try the site (not from an old bookmark) again. More - Delete browsing, search and download history on Firefox

Note, 'JavaScript' which I think is what you are referring to, is enabled by default, and is nothing to do with 'Java' - Why do Java, Silverlight, Adobe Acrobat and other plugins no longer work?

If your question is resolved by this or another answer, please take a minute to let us know. Thank you!

Long story short, there is a difference between "safe mode" and just disabling all add-ons and extensions. Previously, I had just disabled all of these. This time I tried "safe mode". With "safe mode" I am able to log into the Washington Post, but only when I use no saved bookmarks and just Google the website and enter it that way. Why is there a difference?

(I use CClean between websites to clean all cookies, site preferences, etc. when I go from site to site. Therefore, there is no history of any kind saved for the Washingon Post. Even erasing the bookmarks for the site, and recreating them, I have trouble logging in when I create a new bookmark. Best is when I erase all references to the Washington Post, including bookmarks, go into safe mode, and then Google the web site and enter it that way. Any suggestions?)

Did you get hit by this ? https://www.howtogeek.com/326742/ccleaner-was-hacked-what-you-need-to-know/ If so maybe a malware scan is warranted by a anti-malware program.

You use CCleaner at your own risk and what it may do to Firefox is not our issue. Suggest you uninstall and reinstall Firefox https://www.mozilla.org/firefox/all/ Full Version Installer

Please let us know if this solved your issue or if need further assistance.

I use the 64-bit version of CCleaner...not affected, nor does the malware show up in the registry or with my anti-virus program.

Otherwise, thanks for nothing.

Be nice now - pkshadow is only trying to help ......

Don't bite my head off, but your system details show that you have two content blocking extensions installed : Ghostery and NoScript - would you please disable them one by one and see if that will make a difference  ?

As I mentioned above already, I have tried it with ALL extensions disabled. I've done those 2, once again, and having them disabled makes no difference with the Washington Post. I have no problems with any other web site other than the Washington Post, and if I have to, I'll use IE11 to log into that account. Again, IE11 has no problems with "Recaptcha", while the most recent version of Firefox does.

I have no problem - and of course I use Firefox,

See screenshot .........

Hi again, you mentioned that it seems fairly OK in Safe Mode. Usually if thing work in Safe Mode it points to a broken add-on, but Safe Mode disables more than just add-ons http://kb.mozillazine.org/Safe_mode

If by chance you are using 'userChrome.css' you can temporarily disable the entries by placing /* at the start, and */ at the end of the code.

I'm betting that "Tracking Protection" may be blocking Google's Recaptcha here. I'm seeing some reports of Recaptcha breaking for Firefox users.

You can try disabling it according to these instructions: https://support.mozilla.org/en-US/kb/tracking-protection-pbm#w_how-to-turn-tracking-protection-off

Tell us if that works.

I came across "Tracking Protection" threads dating back to 2016, and tried disabling that feature several days ago. That step does not fix my problem.

I don't know what 'userChrome.css' is or whether I'm using it.

At this point the problem is only with one specific web page, a page that works correctly with Internet Explorer 11. I'm not going to bother with this issue with Firefox anymore, and will wait to see if the issue clears itself up with future Firefox and Add-on updates. Please close this thread as "unresolved".
