Hi,

Is there any reason firefox would flag an mp4 file legitimately?

• The file extension and file type are absolutely mp4.
• There seem to be no mp4 related zero days.

Does Firefox perhaps just treat all downloads from suspicious domains as malware? Is there a zero day I missed? Is this based on some missing metadata on the file or something?

Thanks for any advice you can give here, I'm scared.

Hi Everyone, My Bank has suddenly decided that ALL cookies must be allowed before letting their customers in -- a requirement with which I wholly disagree. My FireFox is set to block anything that moves, and supported by Ad Blockers and Ublock too. Is there a way in which I can configure FF to allow me into the Bank site without having to change my "secure" settings every time? I am no computer genius - so please make it simple for me.

Thanks everyone.

I'm getting daily warning notifications from Mcafee about some virus. Don't even have Mcafee. When I go to Settings -> Privacy & Security -> Notifications, there is no Settings button to modify push notifications.

How can I get a list of all the sites that are set to "always open" in a specific container? For example, I want to see a list of all the sites set to always open in the Work container. I would also like to edit the list without needing to manually visit each site.

I'm an old Firefox user. Thank you for excellent Browser!

However, I've seen some bad things in Firefox 89, so I'll report it. After upgrading Firefox to 89, access from behind the proxy no longer reaches all addresses beyond the firewall. I noticed that the page opens correctly when I play around with the settings, which is related to the HTTPS-Only Mode and Automatic proxy configuration URL settings. I specify the address of "http:" in the Automatic proxy configuration URL. In that case, if HTTP-Only Mode is ON, it seems that the proxy configuration file cannot be read correctly. When I turned off HTTP-Only Mode and reloaded again, the page was displayed correctly. Alternatively, I can give up the specification in the Automatic proxy configuration URL and switch to the manual specification. That said, before 89, all settings were displayed correctly, so I think it was a trigger for the change in 89. Is there anything you can think of? Is such a phenomenon happening in other people?

Hi, I have tried all day trying to get rid - of SaveFrom.net Helper - no luck. Latest Firefox running on latest Win.10. So frustrating, tried all sorts of tricks and nothing works Cheers,

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.

Hello, I use dark mode extensions extensively :) and I really dislike light mode pages. However, Mozilla pages refuse to be changed due to the fact that they are "protected" by default.

I don't really care for this protection. Can it be disabled?

When i click on the lock icon in the address bar, nothing happens (I would expect to see the encryption and certificate, but no widget opens). When I right-click into the page and select "View Page Info", "Security", "View Certificate", no certificate exists. Only generic info is shown (Servers+Authorities). Also an error is reported in the system log, confirming that no certificate exists: JavaScript error: chrome://browser/content/browser-siteIdentity.js, line 642: TypeError: issuerCert is undefined

Questions:

• Why does Firefox show the lock icon while no certificate exists?

• How does Firefox establish a secure connection without having a certificate? (From my understanding a certificate is needed for TLS to work.)

Version used: Firefox 78.12.0esr ('Mozilla/5.0 (X11; FreeBSD amd64; rv:78.0) Gecko/20100101 Firefox/78.0'), no add-ons or plugins.

Can FF have a function that deletes cookies and trackers upon closing a Tab as well as when I close FF?

P.S......I have not browsed any extensions for this as of yet...

Yesterday I went to my history to locate a prior site I had visited. There was only 1 site in history, which of course surprised me, and it was to CapitalOne.com/link accounts. This is my credit card company. I removed Firefox from my Macbook and then re-downloaded Firefox and installed. Nothing has changed. My settings are correct, meaning that I should be able to have sites visited in history, yet only the one site populates, and I've been to a lot of sites today....the credit card/link accounts site is the only site that is in history. You can imagine how nervous I am right now about doing anything on line. I sure hope that someone will help out here.

Manage Exceptions button for cookies is not working for me since FF88 or 89, don’t remember which version precisely. I click on the button and the dialogue box that would normally appear to set exceptions does not pop up. Moreover it looks like when I click on the button the user interface on that tab freezes for a period. My FF profile is customised. I know if I start with a blank profile the issue goes away. I have another that works fine. However I would rather try to fix this issue in my current profile. I poked around in about:config but so far have had no success.

Any ideas? I searched google but could not find anything. Also checked mozilla bugzilla a while back without success. I am using FF 92 on Arch Linux.

Hello! A site kept popping up a confirmation window for an action I was trying to take, and in the confirmation window, there was a checkbox for something like "don't allow [this website] to prompt me again" (that's as best I can remember). I checked the box thinking it would just allow the action to happen without the confirmation window, but instead, the site just won't take that action anymore. How can I undo this setting? Thank you!

How do I disable the login prompt for Password? I was on the phone troubleshooting a site I was having problems logging into, and the login for Password kept popping up every few seconds. Even after canceling it would pop up again after a few. I did not want to log into Password because the previous saved username/password would mess up the troubleshooting.

Firefox is redirecting a particular http:// site to https:// Can't figure out how to stop the redirection. It is an unsecured site I am trying to access. Tried various fixes from the community to no avail.

The redirection started earlier this month.

Hi,

my Firefox suddenly stop autologging my to Facebook or Gmail. After every restart of the application, I have to accept again cookies on every site. I have followed these steps and nothing helped. https://support.mozilla.org/en-US/questions/1176200

Then I tried to restore my default settings and autologin works again. Until my Mozilla synchronised with my account.

Can anyone, please, help? Thank you.
