I simply want to use a password to open Firefox. I don't want to set up Firefox sync. How can I set up a simple password as permission to open Firefox without accessing sync?

Firefox on my pc loads Ebay.com with Chinese characters, not English.

This ONLY happens on PC (mobile phone is fine, same firefox browser) only with firefox (Duck Duck Go on my pc works fine) and ONLY when opening Ebay.

Problem started 4/29. I have done: computer update/restart, firefox update/restart, clear cache in firefox

Thanks for any help. I also have Ebay looking into this.

Every time I open Firefox another blank window opens behind the main Firefox pages . I see it when I close Firefox so have to close that too. There is no URL in the window just a blank page.

I am able to start FF with no problem. I open a few tabs and then without warning I can't access any of the sites without closing FF and restarting. Then the whole cycle is repeated. I am considering getting rid of FF this started just over a month ago.

I have played "Hero Wars,Dominion Era " for years on Fire Fox...They did an "update" last week(Thursday or friday 04/25-26?24)and I haven't been able to log onto the game itself since...I can still open the Hero wars home page,I can get into my "discord" chat etc etc etc,but I cannot get into my individual game.(If it helps,my Hero wars game ID # is 10920140)...I had to start playing the game itself on Google Chrome...I am hopeing you can help find a solution as everything I do is from Fire Fox & I really don't like chrome :(...PLEASE Help me resolve this if possible! ( Nexus suggested I use "Incognito" on FireFox ( I remeber that from a few yrs back,but honestly,i haven't used or seen "incognito" since :()

I've set up a second profile to keep my personal and work browsing separate. When I reopen my non-default profile, it doesn't restore the previous session's tabs. I have "open previous windows and tabs" checked under Settings > General > startup in both profiles. Please advise.

When logging into an account there are multiple usernames (incorrect or older.) I would like to remove or delete them, but keep the current passwords.

Is that possible without deleting the account?

Thank you, rldelahay

So I'm having issues playing 4K videos fully on one YouTube channel: https://www.youtube.com/@ClearviewDriving

For some reason anything above 1080p gives me bad stuttering but on other channels videos don't stutter or freeze when playing 1440p or 4K quality.

Firefox is updated, I don't use Extensions other than Ad Blocker and I have that off on YouTube anyway. Seems strange that it'd only affect one specific channel.

I have a very good gaming PC too so the hardware isn't the issue.

Hello, I'm looking for a way to add a shortcut, similar to:

CTRL + Click = open link in new tab SHIFT + Click = open link in new window

What I want it to do is open a link in a Private mode window, to avoid having to open the right-click menu.

I came across this person asking for something similar (they specifically want the private window to not appear on top, I do not care if it gets automatically focused or not) https://support.mozilla.org/bm/questions/1317416

The only answer links to a list of "command line options" and points to the private ones. I understand how you can use these to change how the Firefox shortcut behaves, or to open Firefox in a specific way from the "Run" command, but I do not know how, or if it is even possible to apply these settings to a specific shortcut-click combination.

I want to enable cookies for outlook and google, the rest I dont want.

I have attempted to look at the cookie's url for outlook and add that to the exception list, but outlook still harasses me with its annoying 2fa

How do I find the actual address to put in the exceptions list to stop this issue?

I have recently refreshed Firefox on my laptop running MacOS. Previously I had changed the full-screen-transition in about:config to be zero, but since refreshing changing the setting hasn't disabled the transition. My config is this currently: full-screen-api.transition-duration.enter 0 0 full-screen-api.transition-duration.leave 0 0 full-screen-api.transition.timeout 0 Despite everything being like before the transition persists... I'm currently on the latest version of Firefox (125.0.3)

I am autofilling an ELSA payment portal. Firefox autofills the payment information correctly. But the program will not recognize the autofilled information and doesn't let me process the payment. I then overwrite all my information and then it allows me to proceed with the payment. I have used the same procedure for years but as of this last week, the autofilled information is not recognized as I click the "Continue" button after the autofilled info is complete, and it won't work. The ELSA source (State of Wisconsin) person said it's a browser problem on my end. No. The online form autofills just fine. Can anyone help? Thanks. Jeff

So on my macbook when I enable fullscreen the anmation is super weird. first it stretches the video to the top and then just expands to the whole screen, when I go out of fullscreen is stretches to the bottom and then goes out off fullscreen. for example on safari it just expands the video until it takes up the whole screen. I have gone in about:config and disabled the fullscreen animation but that did nothing.

I'm new to firefox and would like to set cloudflare for DNS over HTTPS but there seems to be an issue. If I set it to NextDNS the connection stays active. But if I set it to cloudflare it goes inactive with the error (NS_ERROR_NET_TIMEOUT_EXTERNAL). I tried setting a custom DNS to OpenDNS and got the same error.

I'm running Manjaro Linux if that make a difference.

New install of Firefox set up with a 'wrong' email account. Tried to use the 'Mozilla account' page to fix this by using secondary email and then making it primary. But the secondary email I want to use is not allowed by Firefox giving an 'Account already exists' error. What should I do?

When I went to start firefox today on my MS Windows computer, I got a file error message saying pathway was corrupted (or something like that) and then the firefox app disappeared from my pinned toolbar. When I went and reinstalled it, all of my saved bookmarks and passwords were gone. How do I get them back?
