I'm trying to configure my router and the instructions tell me to go to https://192.168.1.1. But the security settings will not allow me to get to that (local network) IP address, and ther.is no option to bypass the warning

Hello,

NOTICE: Currently using Firefox 120.0.1 "Update disabled by your system administrator" I am unable to update the browser, the computers are from the public library.

Like I state in the Subject, I configure the browser to strict privacy level, and I am able to visit any site I want. No problem. But on all of these, when I click the lock icon on the address bar I read "Connection verified by a certificate issuer that is not recognized by Mozilla." In fact, right now, I am visiting this website and I got that notice. View image "Firefox broser does not recognize the certificate issuer fortinet but I can visit the firefox suport website - Screenshot 2024-01-28 172732.png"

WOW... View the image "certificate issuer not recognized by Firefox - fortinet - when visiting support.firefox.com - Screenshot 2024-01-28 173041.png" for some of the info I get if I view more information about the certificate.

Then, after I logged out, the "Clear cookies and site data" link that appears after clicking the lock icon I mentioned before do not appear.

View the image "UNable to clear cookies and site data - proton.me - Screenshot 2024-01-28 141951 - edited.png"

In this same computer, I got the control "Clear cookies and site data." View image "able to clear cookies and site data - virustotal.com - Screenshot 2024-01-28 141825.png"

So more than one question:

I read other posts where users are unable to visit a website which has a certificate issued by an issuer that is not recognized by Mozilla. Why am I able to visit these websites?

What can I expect of the non appearing "Clear cookies and site data" link I described before?

Are these computers like totally hacked?

I AM ATTACHING AN IMAGE THAT MAY HELP WITH MY QUESTION. I USED TO HAVE MY HOME PAGE ICON SHOW UP BUT IT NO LONGER DOES. SEE ATTACHMENT. HOW CAN I RESTORE THE HOME PAGE ICON? PLEASE REPLY TO [removed email from public]

Thank you

I just tried to connect to YouTube & get "You're offline. Check your connection." I assume this is due to a DoH connection issue. I can connect in Chrome. My Firefox Mozilla Connection Settings are "Use system proxy settings", though I have set this to "No proxy" in an attempt to fix this - didn't help.

Under Privacy & Security: "Enable HTTPS-Only Mode in all windows", "Enable secure DNS using: Increased Protection" - tried "Default Protection" - no help. Using Cloudflare default.

It has been a few months since I tried YouTube - not sure what's up. It works in Firefox on my phone..

Firefox use a lot of CPU time ( it reaches 100% ) while watching youtube videos in 720p on Windows 10, and videos lags and stutters too much. Not using any ad blockers, non of plug-ins are on. It does work just fine on Ubuntu on the same machine Vids also were working fine on previous popular web browser known for its spyware

Using hardware acceleration is on in browser settings. Specs are: CPU: Intel(R) Core(TM) i5-3230M CPU @ 2.60GHz 4,00 GB x64 Windows 10 Home edition 22H2 GPU: NVIDIA GeForce GT 635M

Firefox version 120.0.1 (64-bit), up-to-date

I can't access this web page: www.fivelakes.settlement.com. This comes up:

Hmm. We’re having trouble finding that site.

We can’t connect to the server at www.fivelakes.settlementaccount.com.

If you entered the right address, you can:

   Try again later
   Check your network connection
   Check that Firefox has permission to access the web (you might be connected but behind a firewall)

I'm a cybersecurity professional and I'm researching about Same Origin Policy, Cross Origin Resource Sharing and how firefox deal with those things. I've find out that versions before 102.1.0esr, cross-origin script GET requests used to attach cookies (Image 1), but in newer versions, it's not happening (Image 2). I checked the release notes but didn't find nothing about this change.

I would like to learn more about what changed and how Firefox is dealing with cookies, SOP and CORS.

Thanks!

So I've noticed that after putting my computer to sleep, upon return Firefox will be unable to load any videos from seemingly any site. The temporary solution to this is to reset my computer as sign offs, locks or returning to sleep do not clear the issue. I've tested on different browsers/sites and can confirm that this is exclusive to firefox. I have booted firefox in troubleshoot mode, cleared my history and given the sites time to load with no luck on any of them.

Is there a solution to this?

Since yesterday (12-December-2023) and continuing today (13-Dec-2023) when I attempt to use the search bar to answer a question eg "five letter words with three vowels" I receive the message 503 Service Temporarily Unavailable. I can enter Google and can then go to Google for a search.

When connecting to a http proxy with a username and a password it says "Proxy server refused connection"

When connect to the same http proxy and turn off its Authentication, it works.

same bug with SwitchOmega & Smart proxy

I recently installed Firefox version 120.0.1 on Linux Lite 6.6 and logged in to my Mozilla and Firefox accounts, then synced my data. In the past, when I used Ubuntu Desktop 22.04, this method would display all the bookmarks I had saved on other devices that also use Firefox. However, for this case, syncing did not successfully display bookmarks in the Firefox toolbar.

I then tried exporting bookmarks to an HTML file, then importing them into the newly installed Firefox using the Bookmarks Manager, but the window for selecting the HTML file did not open, so I couldn't import bookmarks.html into the new Firefox installed on Linux Lite 6.6. I also tried restoring from the Bookmarks Manager, but the window for selecting the HTML file did not open either.

Is there another way to transfer these bookmarks to the newly installed Firefox on Linux Lite?

I have no audio from Firefox browser. Every other browser and app on the PC works fine. I have tried reinstalling Firefox, and using other Audio devices (speakers, different headsets, etc)

I want to delete all my web certs except for the top seven, which cover 99.32% of current web certs. I specifically do NOT want the EU Cyber Resilience Act to have the ability to insert their certs into my root store, enabling their member countries unfettered power to compel acceptance of their certs.

I tried following https://wiki.mozilla.org/CA/Changing_Trust_Settings, but this must be for an earlier version. I don't seem to have an Options/Preferences window. On the other hand I am pretty old & maybe just can't find it....

Any hints on how to do this?

Dear Community,

Just like to ask how I could get Firefox to show a dark mode for all apps that I open, please? I know that changing the settings on Firefox to Dark makes the browser show only a dark mode. However, when I search for other sites, they show up as a white background. How can I change this, please?
