Thanks very much for your prompt response! The log-in page accepts the information but then goes into an endless loop, and I never get logged in. This didn't use to happen when the log-in page was smaller and centered in the middle of the page; now the log-in has become a whole new page.

I have contacted the NY Times Customer Service and e-mailed them copies of the old (working) log-in page, as well as the new (non-working) page, both of which are attached for your perusal.

They are aware that I use Firefox as my default browser, and told me to try logging in via Internet Explorer, which did work with the new page, but also told them that I don't want to use IE solely to get NYT access. That's when they told me it was a Firefox problem, and not theirs.

Any suggestions/fixes for this situation will be greatly appreciated!

They may have changed how the page is displayed.

Make sure you are not blocking content.

Start Firefox in Safe Mode {web link} by holding down the <Shift> (Mac=Options) key, and then starting Firefox.

A small dialog should appear. Click Start In Safe Mode (not Refresh). Is the problem still there?

One issue that seems more common lately is Firefox's Tracking Protection feature. When it is blocking content in a page, a shield icon will appear at the left end of the address bar next to the padlock icon. This article has more info on managing this feature: Tracking Protection {web link}

Thank you once again, FredMcD, for your rapid response and assistance.

I tried starting Firefox in "Safe Mode" and it did work; however, none of my toolbar bookmarks appeared, and I had to access the NY Times web site via the search feature.

Must I now use the "Safe Mode" any time I want to access my NY Times account? Is there any way that this "blocked content" can be overridden when not in "Safe Mode?" If I must do this every time, it will present a major inconvenience, for sure.

I have already tried "turn off tracking protection for this session" by opening the "shield"in the upper left-hand corner - but still could not log in. Should I try "Refresh Firefox" instead?

Any additional advice you may have will be enormously appreciated!

Safe Mode is a troubleshooting mode that temporarily turns off hardware acceleration, resets some settings, and disables add-ons (extensions and themes). If the problem goes away, that tells us one thing. If it does not, that tells us something else.

It could be the work of one of your add-ons, or it could be Hardware Acceleration. How to disable Hardware Acceleration {web link}

Type about:addons<enter> in the address bar to open your Add-ons Manager. Hot key; <Control> (Mac=<Command>) <Shift> A)

In the Add-ons Manager, on the left, select Extensions. Disable a few add-ons, then Restart Firefox.

Some added toolbar and anti-virus add-ons are known to cause Firefox issues. Disable All Of them.

If the problem continues, disable some more (restarting FF). Continue until the problem is gone. After, you know what group is causing the issue. Re-enable the last group ONE AT A TIME (restarting FF) until the problem returns.

Once you think you found the problem, disable that and re-enable all the others, then restart again. Let us know who the suspect is, detective.

It turned out that it was the Privacy Badger add-on that was causing the problem with logging into the NY Times site.

Thank you very much Fred McD for your interest and assistance in helping me to resolve the issue!  :-)
