Diagnose Firefox issues using Troubleshoot(Safe) Mode {web link}

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

Many site issues can be caused by corrupt cookies or cache.

Warning ! ! This will log you out of sites you're logged in to. You may also lose any settings for that website.

When you log in to mozillaZine, there is a checkbox for setting a persistent cookie. Does it help to check that?

EDIT: I find I can still Login BUT IF I'm logged-off the Forum I have to enter Login data and RE-Chk the Log Me in Automatically Box each time - setting isn't permanent as implied. BUT, I can at least login.

@jscher, I just posted in the Mozillazine Forum about this issue AFTER trying your suggestion. I'll advise Hans V at Eileen's Lounge Forum to try it (he sounds like his Same Blocked-out experience was Before 95.0.2) and we'll see IF this suggestion lasts. One of the 2 guys posting one-site Login Issues in Mozillazine FF Sppt would have ONE success after a new trick, and then the Failure would return Hope this works consistently. MANY Thanks!

The http://forums.mozillazine.org has been much more reliable compared to https://forums.mozillazine.org which started as of last Friday or even later Thursday.

The very recent mozillaZine forums login problems is Not due to Firefox 95.0.x

Note that mozillaZine recently started supporting a secure HTTPS connection, so you may have to create a cookie allow exception for https://forums.mozillazine.org, especially if you use "Delete cookies and site data when Firefox is closed".

Thanks to All of you! Fred, I had tried all of your suggestions but appreciate the help. cor-el, I don't Clear cookies at close but made HTTPS Forum exception anyway.

In HTTPS I could Not LogOUT Until I Turned-OFF Enhanced Tracking Log Me in Auto Each Visit is Not a permanent check for me; I Manually chk it Ea Login BUT it works with saved password or manually. Grumpus post below in Mozillazine Site Discussion Forum about Successful Login BUT Control Panel Mod wanting LogIN AGAIN, mimics our HTTP Forum Can't LogIN at All scenario.

[quote =" Grumpus"]There appears to be some load issues with the Https even with the little box checked Trying to open UserControl Panel requests log in after a successful Forums login. Something appears to be freezing the page loads and having entered the login info; logs out. Return to Index page seems OK but best guess is it's something from Google as panel to the right is only partial. Update: from a few minutes ago: Changed cookie restrictions an page loaded, not an improvement, side panel loads slow or partial (several times). Would rather block all cookies, also looks like Amazonaws servers still managing to block page loads or at least partially restrict them. Not allowing cookies returns to site logout./quote
