Is it safe to clear the Firefox(Android version) app data and caches from the device settings? I do clear both really often to free up space(some times even multiple times in a day), but i don't know if it can give problems... I don't care about my history and logins being lost since its expected, but i don't want the app to glitch, not updating or maybe lose security features or ending up with corrupted files or anything like that. Also, with the new update (142.0.1) a new look for the menu was added, i updated the app but i saw no difference, in the past when doing the clearing a new Firefox menu showed up, changes between clears(also, Firefox is my default browser, if it can help; also, could rebooting my phone after clearing data and caches give some problems?), i hope its not because of my frequent clears. Thanks to anyone who can help me figure this out, if any more info are needed i will be happy to tell you more about it. I don't know if im being paranoid or anything but better safe than sorry.

Hello Mozilla. Recently my wife and I have had a new experience with our bookmarks. When we display a list of bookmarks, part of the list runs off the page, so, we cannot see the complete list.

In the past, when we would request this list, if it was too long to display downward, it would then automatically shift upward, so that the entire list could be seen.

Has this feature been dropped or altered in anyway? Is there anything we can do to regain the feature?

We are using Ubuntu 24.04

Thanks. Curt

As of a two days ago, passkey functionality in Firefox is not working (v142.0.1 on MacOS 15.6.1). I have a passkey setup with Google, and when I sign in and the popup should appear for the passkey, it no longer does. This also causes Firefox to become unresponsive and must be force-quit. Any solutions?

Hi guys, Had Firefox as network default browser for decades. Now I have a problem with my DNS pihole filter, firefox just goes around it. I've read countless articles on how to stop this, I've tried DoH 0 and DoH 5, I've placed a file policies.json in a distribution folder. I've tied everything I can find on the net. Nothing and I do mean nothing, had the slightest effect. Firefox goes around whatever I try.

I've spent many, many hours on this please tell me how to kill this, I'm forced to use another browser at the moment, which is painful.

version 142.0.1 64bit W11.

Thank you Bob.

All, most recently I'm having problems with uploading files from my PC to respective internet platforms. It started with file uploads to ChatGPT, whatever I tried, the upload stalled and ultimately failed. Second platform was Vimeo, same problem, file upload stalled and finally failed. Such problems do not occur when using Chrome as browser, or when using Firefox via my Android. Never had such problems before. Firefox runs on latest version 142.0.1, cache is empty and all cookies deleted. System details: Desktop PC, Win 10 Pro, Vers. 22H2, all updates included. Have the same problems on a different Desktop PC. Very much appreciate you feedback and ultimately solution of the problem.

Kind regards, Hanns-Georg Büschelberger

At the end of each session, I ALWAYS delete my cookies and history. Unfortunately, I have been unable to do this. (At the moment, 2.9 kb remain.) Please advise as to how to accomplish this, and, if the problem happens again, how to remedy it.

Sincere thanks,

Getting ready to replace my computer. Is there a way to take my Firefox bookmarks and passwords along with me. I know there are 2 profiles in different directories.

c:\users\jer\appdata\roaming\mozilla\firefox\profiles AND c:\users\jer\appdata\local\mozilla\firefox\profiles

Don't really know difference between roaming and local, except roaming is a lot bigger.

I doubt I could copy the whole profiles as they would contain information that is about current computer and wouldn't work on new computer. However, it seems that I have read or seen there are files within these profiles that just contain my bookmarks and passwords and they can be moved to another profile.

I just need to know the name of the files that hold his information.

Any help would be appreciated.

After the latest Firefox update, some websites are not displaying correctly (fonts/images/layout broken). I already tried clearing cache and disabling extensions, but the issue remains. Is this a known problem, and what else can I try to fix it?

Hello, FF support forum,

I think I have seen a Container retain my login to a site when I open it again after closing it. Is there a way to configure Containers so that they are mini versions of the dump-cookies-temp-data when I close Firefox entirely? I would so love that functionality.

Regards, G.W.

I'm having issues using Firefox with the Facebook site. Groups are slow to load and sometimes the chat and notification windows take forever to load with shimmering panels or a wait cursor displayed. I've cleared the cache and deleted the cookie, but that didn't rectify the issue. I don't have a problem with Edge.

I can NO longer log into my BANK, I changed the security settings back to "standard" but I STILL CANNOT LOG INTO MY BANK. it's website acts as though I'm a new customer & want's me to open an account,I ALREADY HAVE AN ACCOUNT & HAVE HAD AN ACCOUNT AT THAT BANK FOR MANY YEARS! I have jumped through many "loops" at the bank trying to fix this mess, but they can't,FIREFOX IS NOW THE PROBLEM & someone needs to find out what they changed in their updates that has prevented me from logging into my BANK.

Здравствуйте! Я попробую описать проблему на английском и на русском, надеюсь получить ответ и решение как исправить то что я хочу.

В версии браузера Mozilla Firefox 68.0 или Firefox 68.12.0esr прозрачность как в предпросмотре при наведении курсора на вкладку, однако в Mozilla Firefox версии 142.0 или 142.0.1 открыв вкладку, вы увидите замыленность или мутное изображение.

Как видите, на предпросмотре лицо девушки нормальное, прозрачность хорошая, но когда я открываю вкладку, лицо девушки становится мутным. Как сделать прозрачным? как убрать эту мутность?

Hello! I will try to describe the problem in English and in Russian, I hope to get an answer and a solution on how to fix what I want. In Mozilla Firefox 68.0 or Firefox 68.12.0esr browser version, transparency is as in the preview when you hover over the tab, however, in Mozilla Firefox 142.0 or 142.0.1 when you open the tab, you will see a blurred or cloudy image.

As you can see, the girl's face is normal in the preview, the transparency is good, but when I open the tab, the girl's face becomes cloudy. How to make it transparent? how to remove this turbidity?

The bookmarks on my taskbar are all of a sudden not showing up. I'm unable to drag them there like I used to. Also, the history and menu button on the upper right don't work now. I've restarted with no luck.

I see the subject error message (with white X in red circle) EVERY TIME I update Firefox. Rest of message reads 'Make sure your temp folder is valid.'

What Temp folder is in use when Firefox is updating?? Update does complete but it is annoying to continually receive error message. There are more than 350 Temp or TEMP directories!!!

Anybody have knowledge of this error and / or how to resolve?
