I have Firefox Settings UNCHECKED to open previous windows and tabs, yet it very often tells me it's having trouble opening previous windows and tabs.

I want it to quit trying to open previous windows and tabs on this computer. How can I do this?

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.

I'm taking my bi yearly Brain test and it wants to access my microphone so I can speak into it but I can't figure out how for them to access the microphone. I've done what Windows told me to do, go to start>settings>privacy and security>Microphone and made sure it was turned on but that didn't work. Is there something in Mozilla that I can do?

Hi, i like to share idea of tab group improvement. I have more than 20 tabs, and i clean, move open tabs to groups every week, to lower opened tab amount, so i don't need to scroll much. But when i want to consume tab group content, i need to read them all to see what i want to consume... Solution, i would like option to sort tab groups by name, that way it will be faster to find what i want. Also it would be easier to find what tab group to add tab when i clean, move opened tabs. I have more than 500 tabs in my tab group. I finally decided to stop YT search, instead clean my tab groups. Thanks for reading.

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?

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!

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

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??

I have websites I frequent like Youtube and my email set to 'remember me' so I don't log back in every time I open Firefox. Recently, for some reason, whenever I close Firefox I am logged out of everything, and if I open it again I have to log back in to all the services I use.

Settings I think may be relevant to this issue:

• Enhanced tracking protection is set to standard
• "Delete cookies and site data when Firefox is closed" is set to false
• "Remember browsing and download history" is set to true
• "Remember search and form history" is set to true
• "Clear history when Firefox closes" is set to false

I have not changed my account settings at all, and this problem has only cropped up in the past few days, leading me to believe it could be something to do with a new update? I'm no expert though, I just know this is driving me mad.

I did not have an account, (i made it js now to ask the question) but every time i opened firefox everything was saved, my search history, pinned pages, PASSWORDS, (which are all gone and its the worst thing in this situation) accounts on multiple websites, and this type things, EVEN when there were some updates to the app. And the latest profile update, yes i was scared for a second that itll all be gone when i made the new profile but i saw theres another profile with all my things saved. But now, i open the app, and its like i just installed firefox. There are some business tings to set up, they asked me if i want to create a new account, some things i just skipped, then i look and its a whole fresh app. No passwords, no extensions i had, no theme i set up, no saved search history, NOTHING. Now is this normal, and my fault because i didnt have an account? Because im pretty sure that shouldnt happen and i really need all those things. But if its my fault then i get it, although im still a bit upset but if theres any way to recover, or prevent this from happening next time, please let me know.
