try reverting your system to a former time when it was operational by executing a system restore point.

if you are back up and running afterwards, i would not delete cookies to your favorite sites.

Hi, thanks for the input. I guess I could try that -- it just seems wildly absurd to have to perform a complete operating system restore point for a marginal browser issue. For the 2nd point, do you think that was the underlying cause?

I had seen your initial message citing a number of steps to take.

It is unclear why many people are experiencing a variety of quarks with the new FF. But when there is no easy tweak that corrects the quark, i say "why waste time? just revert back to a functional state and move on with enjoying life again"

So this is why i offered my suggestion of simply re-instating the system to a functional state.

And if your FF operations resumed functional again, then dis-engaging the FF update feature would keep you from experiencing the issue again.

Completely understand. I'd rather not revert my firefox version as it has never provided problems before... but I get the gist. If there is no other way I guess I could try it -- not a fan of resorting to previous versions for resolution of problems but I get it.

I don't see anything particularly unusual about those settings.

Have you noticed any certificate/secure connection errors?

Could you set Firefox to use "No Proxy":

• Windows: "3-bar" menu button (or Tools menu) > Options
• Mac: "3-bar" menu button (or Firefox menu) > Preferences
• Linux: "3-bar" menu button (or Edit menu) > Preferences
• Any system: type or paste about:preferences into the address bar and press Enter/Return to load it

In the search box at the top of the page, type proxy and Firefox should filter to the "Settings" button, which you can click. Select "No proxy" and then click OK.

Any difference?

Hello m0dulus,

I did a little checking on my system and i think it would be worth a try to delete all the cookies for google - that is if you have not done so yet.

And when the cookies are deleted, then it will wipe the slate clean, per se, so you can rebuild those cookies.

I have attached a snip of what the cookies look like in my FF.

Nope, still nothing.

Still didn't work, unfortunately.

This is an alternative log-in: https://accounts.google.com/login Otherwise, https://mail.google.com/

Yep, both links lead to the same issue: "Sign In to continue to Gmail." no matter what I type in, the blue bar on top of the box starts spinning, it never loads and an error shows up.

I hope this issue resolved by now, but I thought of one additional thing. Most customized preferences are stored in a file named prefs.js in your active profile folder. So one possible troubleshooting step would be to temporarily remove that file (while Firefox is not running) and see whether anything changes on the next Firefox startup when it uses default settings. This could break some other things, so probably it's a good idea to make a backup first:

Back up and restore information in Firefox profiles

Then this article has the steps to get to your active profile folder:

Profiles - Where Firefox stores your bookmarks, passwords and other user data

You can right-click > Rename on the file and hide it from Firefox with a name like prefsOLD.js -- if your Windows hides .js extensions from you, you can turn those on if you like: https://www.bleepingcomputer.com/tutorials/how-to-show-file-extensions-in-windows/

Hi, still not solved :\ -- I tried your method and google still doesn't respond at the sign in screen. But thanks for the idea, I was curious if that was the issue.

Also want to note: I tried creating a gmail account just to see how that played out and it still didn't work. Blue bar continuously spinning and eventually says "Something went wrong". At this point, I'm completely baffled. I want to suggest it might be on the google side -- but all other browsers and logins work. It is only firefox.
