So today i accident clicked clear data because i thought i clicked clear cache now i lost all my password and previous tab and more how do i recover back in android? :( is it lost forever?

Unlike before, many sites that I visit regularly, I am now having to log in every time I visit, including support.mozilla.org.

Did I unknowingly change something, some setting? or perhaps it's due to an addon?

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.

version 145.0 problem with bookmark bar not showing when set on 'always on" setting. I have replaced the places.squlite folder with another one from a previous computer. there is only one profile available in the user lib on my mac os Tahoe and have done this replacement file numerous times in the past so don't know the the problem is. Any help would be apreciated.

Sometimes, when I have multiple windows open, closing a window won't completely close. It leaves a blank area where it was, the title of the window is displayed, but clicking in the area just switches to one of the other open windows, and there seems to be no way to finish the process. This has been a problem through the last few Firefox updates. Any thoughts? OS -- macOS Tahoe 26.1 Firefox -- 145.0 (aarch64)

I love Firefox for Mac, but, on iPad and iPhone, it's impossible to use extensions such as Winger to save tabs. Too many times, I've lost 100 to 200 tabs at once, and so I switched back on iPad and iPhone to Safari. I never had a problem with Safari's built-in window-tab saver on iPad and iPhone but lost thousands of tabs on Mac, hence my move to Firefox on Mac.

On Firefox on Mac, when I click on Firefox View, I can view tabs from other devices, but there's no way to copy multiple tab links at once (you have to go one by one). If I ever were to shift back to Firefox for iPad and iPhone, does anyone know of a way to easily save 100 to 200 tabs from these devices?

I would rather use Firefox because I can't stand how Safari opens links from outside Safari, forcing the use of some new default window over the named window I already have open. It's so much work to micro-manage this browser.

Thank you kindly and enjoy a super day!

I am having trouble accessing The Washington Times with Firefox. Every time I click on a story, it comes up, but then immediately the screen shades out to a gray screen, and nothing works. Also, if I open The Times website and click on sign-in for my account, nothing happens. If I go directly to the Times website and try ti sign in, the screen greys out again. This just started happening yesterday. If I go to a laptop with an earlier version of Firefox on it, all works just fine. Also, if I access the Washington Times with Microsoft Edge, it works just fine. Would appreciate it if I could get some help here.

google is saying cookies are disabled when using FF to login. This was working Privacy is set to STANDARD and I went into settings and removed google.com as well to no avail.

How do I fix this?

Thanks leon

I uninstalled Firefox on my computer and reinstalled it, but when I logged in, the account couldn’t sync, it was as if the sync couldn’t retrieve any data from the server. Nothing happened at all.

On my Android phone, the data is still there, but when I tap “Synchronize now,” nothing happens either. I’ve tried signing out and signing back in multiple times, but still nothing works.

I also tried switching to a different computer and a different internet connection, but it still didn’t work.

What should I do now?

Tonight I received a notice that a new version of Firefox was available and asking if I wanted to download it. It showed me the new Kit mascot so I decided to let it install. It seemed to install normally but when it tried to open what I guess is a welcome/new features page, it crashes, and just showed a prompt to try again. This continued in an endless loop and I had to shut it down. Unfortunately I no longer had a functioning version available that I could find so I downoaded the ESR version to be safe (ver 140.5.0esr) which I am now using. Somehow I was able to recover bookmarks and hopefully other saved info. Can anyone advise what has happened? I have used Firefox for many years and never had this sort of problem before. Running Windows 11 on a new Dell i7 PC.

I updated Firefox to 145.0 this morning, and after Firefox had restarted, it had lost all bookmarks and the bookmarks toolbar. I have spent all day following links to correct the problem and got nowhere. I have restarted Windows and Firefox countless times - no change. I've even tried reinstalling Firefox over the existing version. If I go to bookmarks > manage bookmarks > restore and backup, sometimes that will load, others not. When it does load, it fails to find a file to restore from. 10 years of bookmarks, links & research vanished.

Can someone please provide a solution (preferably in Layman's terms) to this??

Would like to test nightly builds of Firefox - how best to get started?

I am a user of Ubuntu and interested in testing the Firefox Nightly via snapstore.

Any pointers helpful.

Does anyone know how to restore a previous profile? I had a situation like this: I had Firefox 140. I decided to upgrade to 147. Then I upgraded to 145 and all my data disappeared. The system is Linux Ubuntu.

Firefox was somehow reset after windows update restart. I was trying to sign in to sync, but sign in button gets blurred/disabled, and nothing happens then. I am afraid that I lost my previous session also.

I was trying troubleshooting mode too, but behavior is the same.

Otherwise I can login to my Firefox account web, and I am logged in on my smart phone still.
