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.

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

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

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?

Firefox just will not print anything at all. I have tried all the suggested fixes; everything else on my computer prints fine to either directly connected printers or to network printers. The 3 other computers on my home network all print to all printers from Firefox. I have deleted Firefox and reinstalled I have deleted all printers and reinstalled When I do try to print with the print queue open, the file spooling briefly splashes up and disappears quickly. If I download a PDF from the web, it will not print from within Firefox, but will print from Acrobat or Nitro I have changed antivirus from Eset to Webroot anywhere. No improvement and in between with no Antivirus, Firefox would not print. Any thoughts, as I had to change browsers and I want to get back to Firefox? Help!!

Firefox 125.0.2 on Mac

When I press shift+cmd+D to bookmark all open tabs, instead of the links being saved to the designated folder, they are all saved to "Bookmarks Menu". The designated folder itself also appears with these links but it itself is empty.

I would expect shift+cmd+D to bookmark all links in the folder and the folder to appear in "Bookmarks Menu". This is what use to happen ages ago. I'm not sure what caused the change in behavior. Anyone have any ideas on fixing this?

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?

I am running the latest updates to Windows 10 Pro x64. One of my monthly bills is paid at

1) https://e.synchronyfinancial.com/

which, in Brave, redirects to

2) https://lowes.syf.com/accounts/login

Inputting either link in Brave gets me to the finish line but the first link above fails in Firefox with the "Secure Connection Failed" message and dumps me at https://www.synchrony.com/accounts/. The second link does the same.

Is there any way to troubleshoot the problem?

I HAVE tried shutting-down Malwarebytes but the result was the same.

This is the only site on which I have encountered this issue. All that I can determine at the moment is that that certificate is from DigiCert and the expiration date is in 2025, i.e., this is not a Symantec cert.

I don't use Google Chrome browser nor do I use MS Edge. After using the Mosaic browser, I switched to Netscape Navigator, then to Mozilla, and, finally to Firefox. I am not looking forward to migrating to another browser. ;-)

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.

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've made an extention which works fine when I test it using the temp mode on firefox. When I attempt to install from file however I'm told it could not be installed as it appears to be corrupt. Below are the package.json and the manifest.json:

package.json

{

 "name": "ext",
 "version": "1.0.0",
 "description": "",
 "main": "contentScript.js",
 "scripts": {
   "test": "echo \"Error: no test specified\" && exit 1"
 },
 "keywords": [],
 "author": "",
 "license": "ISC"

}

manifest.json

{

 "manifest_version": 2,
 "name": "SKUORG",
 "version": "1.0",
 "description": "Organises SKUs on WooPage",
 "permissions": [
   "activeTab",
   "webNavigation",
   "<all_urls>"
 ],
 "content_scripts": [
   {
     "matches": ["<all_urls>"],
     "js": ["contentScript.js"]
   }
 ]

}

I have tried on two devices / installs of firefox and have followed the steps I could find on this page : https://support.mozilla.org/en-US/kb/unable-install-add-ons-extensions-or-themes#w_corrupt-extension-files

If you have any suggestions please let me know.

I've been having issues with the websites that I commonly go to no longer appear on the autosuggest list. Websites I haven't gone to for ten years appear when I type in a given sequence rather than more common ones. Website that I go to every day no longer appear.

Multiple websites suggest this sequence:

I follow the "clear all.." and nothing changes. How can I start anew and have FF re-learn my url history?

I installed Firefox on a new Dell laptop and imported the bookmarks from FF on old laptp. On my old laptop things are OK. On the new laptop Firefox will ONLY store new bookmarks in the Recently Book... folder, no matter how many times I choose a specific folder from the Location dropdown, even if I only choose Bookmarks Menu without subfolder. Show Editor is checked. I have to manually move new bookmarks from Recently Book..... This is annoying. Can you help? I have not found a forum with this question.

Several instances of this "verification.exe" malware appear on download history when firefox is opened as shown. Remove from history or clear downloads doesn't eliminate them. They reappear whenever firefox is opened.

Suggestions to eliminate this nuisance welcome.

I am unable to reach Facebook on both Firefox and Waterfox.

Other browsers (Opera, Edge, Chrome) are able to access Facebook.

I can access other Meta-owned sites (Messenger.com, Instagram, Threads) on Firefox and Waterfox.

This issue exists on both my desktop (Windows 10) and laptop (Windows 11).

This issue does not apply to Firefox for iOS or the Facebook app.

All apps and OS's mentioned are up to date.

This has been going on for over a week now.
