Hello,

I have two windows in Firefox that I would like to tile so that I can compare the contents of each. Is this possible ? Regards

Same Problem as here but thread is archived: https://support.mozilla.org/en-US/questions/1465988

It has always worked great until now, but it seems that it no longer works with Firefox 147.0.1. Does anyone have any idea how to fix this?

I have entered in exceptions for a web page that Firefox continues to block....I have gone through your steps 4 times now...one time out of 4 you actually let the web page through....since then you don't again...what is wrong with your system? as I am not receiving a download link from the intended exception due to the fact you are not honoring it....

Dear Support,

Since ages ago I've always logged into Firefox and turned on sync so whichever device I was on (or if I have formatted my PC) I would still have acces to my browser history, tabs etc. Today I've formatted my PC to switch from win 10 to win 11 and logged into firefox as usual, but after trying to Sync nothing happens. My tabs, my history, everything is empty for some reason and I cannot find my original device (the one from a few hours ago connected in win 10) in my connected devices list either.

Please help me, my whole life is in that sync :(

Best Regards, Peter

Hi I keep getting this error on Firefox. I did disable all my extensions prior to this image shown to see if it was an extension causing an issue to no avail. I also looked for an update for Firefox and saw it was up to date. I also attempted to refresh Firefox which was a successful refresh however the error persisted. After refreshing I fully uninstalled Firefox and then reinstalled however the issue persists.

This error is shown however if I refresh the page sometimes the page freezes as if it lost connection and sometimes it reloads as per normal with the video playable.

Just updated the latest. Unable to use my account?? Unable to contact you from my laptop? What happened!!!! [phone number removed] cell phone. Please message me on this device. 1/21/2026. . 6 am

I recently opened Firefox to see a new flagged warning under my toolbar that says "The security sandbox is disabled. Your configuration is unsupported and less secure."

I have gone into about:config and adjusted every security.sandbox element to see if that would change anything; it did not.

I am running on Windows 11 Home so I cannot install or properly run Windows Sandbox.

I would either like a solution to enable the sandbox once again, or just remove the notification from the toolbar.

Hello.

1. How to save a tab group without closing it? 2. How to make individual tabs in a tab group permanent? (So when you close a tab group only the permanent members are preserved.)

Firefox has always had problems processing forms. Not every time, just once in a while and that can be so infrequent that I don't see the browser being the issue until I contact support at the company whose site I'm having issues with. This could be processing a checkout form on a site after purchasing an item. This latest incident involves me trying to fill out an open enrollment form for benefits at the 3rd party benefits administrator because I got fired in Nov [along with many others]. I tried to fill out the re enrollment form and it simply went in circles and never completed. The name of the benefits administrator is "bswift" if that makes any difference. You know what they told me when I called and said I was using Firefox? "Well... you should be using Chrome or Edge." Doesn't happen often, but companies know there is a problem with Firefox. In that case, why are there ZERO help articles on this site on the issues of forms? I tried phrasing the question 5 different ways. The last one gave "Found 52 results for ‘forms don't work’ for ‘All Products’ ". If the companies that I call know that Firefox is an issue, and this has been going on for a LONG time, years, then why has this not been addressed? Either by Mozilla, or by someone in the Forums? Not a single one of the 52 results were even close to my issue. I am simply at a lost to understand why I am the only one in the world forms don't work for. I have to stop, move to Chrome, and start whatever it was I was doing all over again. I have been using this product since Netscape 1.0, and was around long before windows or browsers existed. Any insights are appreciated. Thank you.

Hi everyone.

Basically when the browser is (I think) idle while watching YouTube, FF is constantly backing up (the timestamp in the backup file name keeps getting updated). From the settings page I thought it once every 24 hours. I noticed from higher than normal CPU usage impacting FF and the Windows search indexer. Which reverted to normal once I disabled the backup.

I checked the about config:

• browser.backup.scheduled.minimum-time-between-backups-seconds

Is set to 24 hours (86400 seconds)

But I also noticed:

• browser.backup.scheduled.idle-threshold-seconds

Is set to 15 seconds(!). Is that what I think it is? Back up whenever there's a 15 sec idle window, regardless of the minimum? Can I safely make that 86400 seconds too, or does it do something else entirely?

Many thanks in advance.

I cannot log in Firefox account. It says I have to log out to log into my account. All I wanted to do is to remove a phone I reset and gave away from my Firefox device logins, but everything quit working with all the AI chaos.
