When I surf Youtube, Google, Facebook and anything on Firefox this following error happen every time. Please help me.


Firefox detected a potential security threat and did not continue to www.youtube.com because this website requires a secure connection.

What can you do about it?

www.youtube.com has a security policy called HTTP Strict Transport Security (HSTS), which means that Firefox can only connect to it securely. You can’t add an exception to visit this site.

The issue is most likely with the website, and there is nothing you can do to resolve it.

If you are on a corporate network or using anti-virus software, you can reach out to the support teams for assistance. You can also notify the website’s administrator about the problem.

When I attempt to access several websites, I am prompted to turn off my ad blocker. As I have not added a third-party software or extension that does such, I assume it is part of Firefox proper. Search as I might, I cannot find any specific reference to such a thing in "Settings". SO...how can I temporarily disable the 'Ad Blocker' device that is part of Firefox? The 'TEMPORARY' part is important, as I do greatly value the function!

Hi!

I want to dump/debug http traffic with mitm proxy: https://github.com/ganskef/LittleProxy-mitm . This proxy generates it's own root certificate which i manually imported to Firefox from about:preferences#privacy > View Certificates > Authorities > Import. I verified that cert shows up after importing it. But I get errors despite of that:

Secure Connection Failed

An error occurred during a connection to www.youtube.com. Peer’s certificate has an invalid signature.

Error code: SEC_ERROR_BAD_SIGNATURE

Is there a way to bypass it?

When I check the connection settings on a website (lock icon left to the address bar) and go to more information I can see how many times I have visited this website. I already deleted my entire history and all the data but I still can see how many times I have visited different websites in the past. Where is this stored and how to delete this information?

The problem is it will show suggestions in the address bar. There is a setting to to remove such suggestions but I only want to remove some results. Why doesn't this part of the "history" gets deleted?

I am using FF 97.0.1 Win 10

Hi,

So I have a kind of unusual problem. I am currently logged into my Firefox account (obviously) and have access to all my saved material/history. The problem is I do not know my current password (the ones saved in the password manager are old/not correct) and I can't reset it without losing all my info. This is mostly a problem because I want to activate Firefox sync on another computer. Does anyone know how I can find out my current password without resetting everything?

Thanks!

Using Firefox 68.12.0ESR. I know 78 is available, I just haven't had the time to test it yet. I delete cookies when I exit Firefox. I want to keep some for sites that I trust, such as this site. I've added exceptions to Allow these trusted sites as documented on a thread somewhere else, but it doesn't work. All cookies are deleted.

Is it possible to keep cookies only for a select group of sites. eg. support.mozilla.com, tomshardware.com, mydigitallife.net, speedtest.net and so on.

Thank you.

Firefox Browser uprated to 92.0 today. Previously whilst browsing Ad's were showing; today I have no Ad's displayed but have not enabled an Ad Blocker on Firefox. A site I use extensively cannot now be properly viewed; I get a message to turn off Ad Blocker. I have set Enhanced Tracking Protection to 'Off' but am still unable to obtain full functionality, I am using standard Firefox Privacy settings otherwise. I am able to browse the site properly using MS Edge. I have deliberately refrained from using any AD Blocking on my part so as to ensure the site in question can be properly viewed. The only Firefox extension being used is Kaspersky Protection; I get the turn off Ad Blocker message both when Kaspersky Protection is on or off.

Hi.

When logged in to google (e.g., gmail) in one firefox tab, I am them auto-logged in to that same google account in any new tab or window I open. Is there a way to stop this?

I would like to be able to have one tab logged in to a google product (e.g., gmail, google calendar, youtube), but retain a "blank slate" when I open new tabs or windows, so that I can browse anonymously or log in to multiple different accounts (google or otherwise).

I have privacy badger and HTTPS everywhere installed in firefox, have set the browser to block all third party cookies, and to never remember history (high security settings across the board) . I tried enabling Multi-Account Containers, but I'm not sure how to use it and also suspect it is a more complicated functionality than I actually need.

I would imagine there has to be a way to "break" the connection between multiple open tabs or windows. Thanks!

HI!

My buddy highlighted an issue, then i re-checked myself and it is worrying to me.

To recreate (windows):

Get any (non-webistaller [not nececarry, to do it this way, but simpler to check]) firefox version (buddy got a fresh portable, i used my kinda privacy fortified one). Disconnect from the internet (plug the cable for fastest result). Make your version usable (install it) Start firefox, and open the Resource Monitor, with the network tab open expand the Network Activity portion (short alphabeticly, by name, check for F for firefox). Plug the cable in.

You soon will see FF will start looking for things, then an adress with a googleusercontet.com will pop up. Does not matter what is the Homepage's default browser, does no matters even if the Homepage is set to blank, this happens.

My best bet would be google safe browsing, but still, without any activity it is already connecting to that?

I know about the Google-FF/Mozilla relation, but this really made me think about why i still like firefox.

This is on fIrefox version 85 in Linux.

Last week I was discouraged to find out that my cache was taking up 2 GB of space, some YEARS old. So I decided to purge it and then keep it clean.

The cache gets stored in two places: the linux home .cache folder AND the firefox profile's cache2 folder.

To keep things REALLY clean I checked the "Delete cookies and site data when Firefox is closed" checkbox, then manually enter the exceptions for web sites I do not want to block. Then I specifically added sites I really despise (google, for example) to the block list.

The data still gets cached, even after closing and reopening the browser the cache is still there (verified both via about:cache and by just looking in the folders).

Even when I purge the cache completely, verify nothing is there (about:cache) after deleting the cache folders from the hard drive, it keeps coming back, like a bad computer virus.

My interim solution is a crontab that runs every hour to clear old cache, but that seems silly. Do these security settings actually do anything? What am I doing wrong?

Hi all :)

From a fresh Linux Debian Bullseye I try to connect to a local machine with Firefox (v97 64-bits) by its hostname (avahi server with default domain "local") with the port 6180 bound to a remote web service port (61 is the distant machine IP and 80 is the forwarded port).

When I want to open this URL : http://bionic.local:6180/ FF displays "We can't find this site ... Unable to connect to server at bionic.local ... check your network connection and firewall"

BUT ping bionic.local works perfectly and resolve the good IP address from the Chromium navigator the same URL works without a problem, I can open the distant web site.

This workaround works : add a static resolution in the /etc/hosts file : 192.168.0.71 bionic bionic.local => so FF works in the expected way for now ! But as I said this a workaround and a bad solution.

I supposed too the port was blocked because I accessed an unusual port. So I tried this without success.

How the hell make that FF v97 allows me to use an unusual port ? Or is it bound to the domain "local" which is no more accepted by FF ?

Thank you in advance for your help. With adelphity, lnj
