There have been numerous times when I click on a video to play (NY Times, WSJ, Universal Class), I just get a spinning circle but no video. Yet when I go on Google Chrome, the video plays right away. What's the problem here?

Thank you.

After a usual, recent automatic Firefox update my passwords and other data (bookmarks, history etc) are missing. The update took place around March 4 and on March 10 I used Smart Switch by Samsung to transfer and sinc my phone data on my pc. After this operation I noticed the missing data and all attempts for the various methods to restore data were unsuccessful. Please advice on how to restore passwords etc..

Ich habe eine Systemwarnung halten und habe versehentlich angeklickt. Defender hat einen Trojaner entdeckt. Dieser wurde entfernt. Jetzt wollte ich Firefox restaurieren. Wie ist das möglich. Was ist zu tun ?

How do I search x-rated or violent content with the Firefox browser without Google safe search puritans blocking my every attempt to do so. I don't what I've done or how to change it. I am just going around in circles of frustration. Good lord it's like I'm back into the puritanical dark age. PLEASE HELP.

I have had this problem in the past, but now its back again. At first I just reset my password every time, then I set up the password to be auto-filled. I have had no sign-in failures for months. At one point i did figure out how to check my sign in history to see the failed attempts, and there were none. That was a long time ago, and I have since forgotten how to check this. The problem does seem to be with firefox as it does not happen with chrome.

I have moved my profile to a different location on the hard drive to make backups easier. How do I tell firefox where the profile is now located. c:\users\med\my data\PROFILES\mozillA\*.deFAUlt

Hi, I'm running Sierra 10.12.6 on a mid-2011 iMac. I installed Firefox 115.33.0 in March '26, but now see a "not supported message" in the browser.

I downloaded the ESR version of this browser, but when I went to copy to the APPS folder it asks if I want to replace the NEWER one that's already there. ???

Now it says I'm running it on the ESR update channel. Did I just go backwards in browsers? When this ESR expires, if a new one isn't provided then, will I still be able to use/update/install Firefox on this IOS on this iMac?

Thanks! Elaine

The sound works for me on Opera (PC Win11), but not on Mozilla - I see it as a bug in the browser... even after clicking on the playback device in the bottom right corner in Mozilla, the sound doesn't start playing...
