I use CCleaner on a regular basis and have been for over a decade and a half now. With CCleaner, I have the ability to disable unwanted browser extensions. Typically, this works just fine but lately, I've been running into an issue where CCleaner shows several Firefox extensions that do not show up in the browser's options menu: Bing, Amazon, Google, Wikipedia and DuckDuckGo. I disable these in CCleaner like I usually do yet they re-appear in CCleaner as extensions when I open a new browser window after disabling them. Are these really some sort of hidden extensions in Firefox? And if so, how the heck do I get rid of them permanently? I don't want any of these extensions. Thanks in advance.

Hi, I have been unable to access any google services (e.g. youtube, google) due to the following error message: Someone could be trying to impersonate the site and you should not continue.

Web sites prove their identity via certificates. Firefox does not trust www.youtube.com because its certificate issuer is unknown, the certificate is self-signed, or the server is not sending the correct intermediate certificates.

Error code: SEC_ERROR_UNKNOWN_ISSUER

View Certificate

Could you please advise how to resolve this? I reinstalled firefox and that did not help. Certificates are installed and have expiry date of 2031. Other browsers are not affected.

Thank you.

How do I stop the "Please complete the security check...hCaptcha...proves you are a human" check boxes from appearing each time I try to open a link in my browser? Thank you

I suspect my firefox account was compromised as I have found evidence of my email being tampered with and certain emails having been deleted and then deleted from my trash. I was able to use an email recovery addon to recover the emails.

I am currently investigating whether the breach was through my email or through firefox, as it is synced into my email. Unfortunately, gmail does not go back far enough to show any session activity beyond the last 10. I am trying to get in touch with somebody on that end to help me determine whether it was just my email.

I am reaching out here to ask if there is a way to see if there is a way to pull session activity on a firefox account. I checked security and found that only 3 devices had been signed onto my account, all of which were PCs/laptops that I owned. I signed out of all of the devices, relogged on my PC and changed my password and setup 2FA. There is a possibility of a fourth device having connected to my firefox but the suspect may have signed their device out.

My only other suspicion of any potential breach through firefox is one of my laptops that I had reformatted and gave away. Could someone have recovered my firefox login on that laptop and used that to sync into my firefox account and then gain access to my saved passwords and so on?

If that is the case, I can follow up on that and see who handled the laptop since it left my possession.

I appreciate any help in advance.

I was on Ancestry.com and went to download a GEDCOM file from my family tree work. I had developer tools turned on by coincidence, and noticed that when I clicked the download file button, a network communication was sent to Facebook! Appears to be a 5.6Kb 'beacon'. I don't see that behavior from Chrome. Why is Firefox telling Facebook what I'm up to on Ancestry.com?

Cloudflare provides a web site https://www.cloudflare.com/ssl/encrypted-sni/# which can test Encrytped SNI. My browser is configured in about:config for ECH as follows

network.dns.use_https_rr_as_altsvc true network.dns.echconfig.enabled

When I run cloud flares test I get a failure for ESNI, should this occur?

I just went to the Washington State Department of Licensing to renew my driver's license. When I ask to "view receipt" it says that my pop-ups are being blocked. How can I get around this? I've been to the "Options" menu and deselected blocking pop-ups.

Hi, I'm unable to change my Firefox Account password.

I navigate to the Manage Account page, click Change next to Password and enter my old and new password and nothing happens. The page gives no indication that the change has applied and my password remains the same.

I have also tried this in a private window, on Google Chrome and on my phone and the same thing happens.

So...

I was on y2mate, wanted to download a video, then uselnk happenned: it redirected me to the page, Firefox froze for about 10 seconds then, everything became normal again... except that the y2mate and redirected pages closed themselves. Even if, for the moment, everything seems to be normal, I already launched a scan with my antivirus (paid one), for me, it is a bit strange. Even if Firefox froze sometimes (probably because of my computer), this time, it was suspect, just the time to download something. I searched up what are these redirected and it appears that's a virus/adware or something like that.

Anyway, could someone tell me what should I do? I know that I should check out the extensions, but I have already done that, and nothing suspicious, only extensions that I have installed before.

Ps: sorry for the possible orthographical/syntax mistakes, english is not my native language.

I believe my FF account was compromised and an unknown person has accessed my synced accounts to commit criminal activity (stolen digital assets).

Where can I find a log of logins/session history, or better yet, can someone from FF support help me find what I am looking for. I checked for a confirmation email but I suspect it may have been deleted and then permanently deleted from my gmail - which according to Google is unable to be recovered.

Hello, Every time I open a new Tab a Google page is opened which is great. Bu then when I Google something it always leads me to a Facebook Search Engine which looks like a scam and it only brings me to a Facebook search. Attached is a screenshot of what it looks like.

Any ideas how to remove this?

This is only happening on one of my home computers and only on Firefox which makes me think it is a bug.

I do use other Browsers with no problem.

I got a new computer and tried to sign into Firefox. I was able to do so but, when I go to see my passwords Firefox wants a "Primary Password". I was able to sign into Firefox and sync to get my bookmarks but, I cannot get my logins and passwords. Firefox keeps asking for "Primary Password", nothing works. My account email is on the 3 line Firefox start menu. Any help appreciated.

All. The answers to all the issues with security errors like SEC_ERROR_INADEQUATE_KEY_USAGE end up with "contact the web owner". In many cases for me, these web sites are not internet sites but hardware HTTP servers (e.g. like a system's BMC or iLO) and there is no system administrator to contact. The web sites open up fine in Chrome. There has to be other solutions (like setting an exception) to work around these issues. Eddy

I was just wondering if you are using Firefox Containers is there any need to use Privacy Sandboxing (Fission) in the Advance Preferences? Asked this before and no reply! Thanks

I have noticed that recently a lot of well-known and trusted sites(eg- youtube) are showing connection not secure (Parts of page are not secure such as images and any information that you share may be leaked -passwords etc) . Sometimes when I reload the site, it again shows connection secure.

Is this a glitch or something to be worried about and is there a solution?

I am just not sure if this is anything to be concerned with, i did a bunch of searches for firefox open ports, but couldn't find an answer

My setting stay like this for Two or Three times when opening Firefox but then my setting automaticly change to (searchmarquis/searchBaron.com for my homepage and my search engine changes to Goggle .com. When I go back into Fiirefox perferences the only search engine available is Goggle.com. this is the 10th and last time of having to reset my perferences in Firefox. Why6 is this happening and how can I stop it???
