I waited for a long time to do an upgrade to avoid problems. Today finally I decided to upgrade to the latest version of Firefox for my iMac, 147.0.1. Before the upgrade I successfully used with zero issues gemini.google.com/app . Now the website comes up, but regardless what I enter as a question I only get an error message stating "something went wrong". The same website works with no issues (TG) with Safari.

Does anyone else experience the same? Is this a known bug with this version of Firefox? Is there a work around for it? Is the solution just using Safari?

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?

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 have opened my account on firefox and it has a very old version of my bookmarks, i have logged in to the same account on both computers and it isn't showing up on the new one

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.

Can I permanently turn off InformationUpdate available' which appears each time I open Firefox. I must click Dismiss to close it. The problem is that after each update, many services to which I log every day, state that I am logging from a new device and I must complete a time consuming procedure of adding a new device in many places. And I don’t need most of the updates.

bold text'I am so fed up with these updates loosing my passwords and data, why ? All my settings are messed up and last time it took two weeks to get everything back, why? I give up total idiots for releasing updates that are sub par!

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.

My Firefox browser on Android is very slow. YouTube videos buffer and lag. Pages take a long time to load. Sometimes Firefox freezes or crashes. Please help me fix performance and video playback issues. My phone has limited RAM and storage
