Free youtube downloader wants my age from Firefox to download popular music videos. I am logged in to FireFox and Free YouTube downloader identifies FireFox as my default browser.

This is really an error for Free YouTube Downloader to correct, but many FireFox users must have solved this already. Any advice?

Thank you!

Hello, When I try to use Mozilla firefox, using this rather than Google chrome I get the following warning from Malwarebyte: Exploit.PayloadProcess.Block, making me feel uneasy. Best wishes, Torbjørn Borgen Lindhardt, Denmark

I would be grateful for some information on container behavior, i.e. I created "permanent" (as opposed to temporary) containers for sites where I want that site's cookies & site data preserved in a container, so I can click "Clear Cookies/History" (or "Clear... when Firefox closes) and the items stored in PERMANENT containers are left alone, while all else is deleted. "Clear ...." doesn't appear to be respecting the permanent containers I have set up precisely to preserve these sites' cookies & data.

I'm not sure what the point of Permanent Containers is, if not to preserve those sites' data, for the sites' later use when you set Firefox to Clear Cookies and Site Data whenever Firefox Closes (or Clear Cookies & Site Data with one click). I expected it to respect data in Permanent containers, as exceptions. Else why not just use separate Temporary Containers for everything? Why bother with Permanent Containers if everything is going to be deleted when Firefox closes, whether it's marked "Permanent" or not? Is there a solution for this? Thanks, -AnneF

Recently, every time I click anything, even to open my email messages, new junk tabs open in my browser and it automatically takes me there. It takes forever to do anything. I looked at my security and it seems fine as always. This has to stop soon or I need a new browser and I've loved this one for years. SOS

I have been watching YouTube for years, issue free. This week I was blocked, as my computer may be blocking ads and thus violating You Tubes policy. How can I find and disable ad block programs/ extensions, thus allowing me to get back on You tube. I can recognize an outright program, but do not knew if extensions are in play that are not obvious to me. THANKS

I use Firefox on Linux-Mint. When I check that I trust the digital certificate "Warsaw Personal CA" this information is not saved. Every time I restart Firefox I have to check this option.

log in at b of a said my computer was a new different device. not true same laptop. now all mt accounts are gone. like Google email says open new account?? whats going on. I am not well versed in tech!! thanks for any any help. I am afraid someone has taken over my computer.

Why in the world am I seeing these tab Groups and Studies

After reading some posts on here I went to about:config and browser.tabs.groups.enabled was set to True. I changed it to false. I never set it to True and haven’t a clue to what Tab Groups are and don’t see any reason for me to have them. I only use about 4 tabs and have no use for any more. But I was noticing a Blue square box next to a tab and clicked on it and it said I had a Tab group which I deleted. Don’t know how a tab group was built, I sure didn’t ask for one and haven’t a clue what they are???

While researching this I seen something that about:studies could be the problem. I looked at it and it showed I was or had been in 4 studies!! All of the studies showed completed. I did not join or ask to be in any studies, what is Firefox doing signing me up for studies? I went to Privacy and Security and nothing under Firefox Data Collection and Use is checked including install and run studies. I have people’s secured data on here and if it gets out I could be sued!

I have run 3 full scans of different virus and all is clear. This must be something Firefox is doing without asking me for permission. I did find that browser.tab.groups.enabled was true, so I know FF must have done that during an update and I set it to False. Some post say FF will change it back to True?

What is really strange is the studies, it says they did 4 that are completed, yet it was not checked in the Privacy and Security section. Can't tell when as there is not a date.

These were the studies:

prefflip-push-performance-1491171•Complete hotfix-reset-xpi-verification-timestamp-1548973•Complete hotfix-reset-xpi-verification-timestamp-1548973•Complete pref-flip-screenshots-release-1369150•Complete

Firefox is running on the front, while I am RDP doing something else, it suddenly prompt for requesting to send cert, I am curious what's it. I did not do anything.

suspend any 3rd party addon, but not sure the way to nail down the issue.

I am in a situation where I need to prove that my browser data has not been tampered with. How can I do this? So far, I have only been able to locate my places.SQLite file, but it is hard to prove that nothing has changed within the file.

Hey team at Firefox, I stream a lot of movies illegaly, animes and shows too on Firefox and one of the most common exploits used by bad people is spyware and injection of malware seems inevitable. even with all the amazing protection features offered by you guys and UBlock origin don't seem enough at all. using a VPN and a amazing browser suite can only go so far. i had the idea of sand-boxing on my PC but a pain to do it every single time and keep a track of everything i am doing. The idea here essentially is to somehow sandbox certain tabs or windows entirely and to be able to pick up where u left off. this paired with the Firefox advanced features and all the amazing extension still available here instead of chrome will make the experience even safer. Hopefully this is something you guys can actually do. More than that i hope this reaches the relevant people at the company not just drowned in a pool of support tickets. I expect no credits or anything like that. I just want to know if its possible and this reach the devs so maybe they make it happen. I do think this is a great idea and a possible feature on here. i can think of more ways to use sandboxing like that but this is just how i want to use it. Kind regards.

Good morning, I need to get off 2FA on my account Firefox kamilmian@gmail.com because by mistake I delete it in my phone and as I remember still have support phone in my configuration but 2FA blocks my option to login. Also I don't know where I have my codes, even after having acces to gmail account and phone. Please help.
