I-Firefox Community Forum

So whenever I click on new tabs, it always leads to a redirect notice asking me to confirm if I want to open those tabs.

I want it so that I don't get these notices, but the links I click on just open automatically. I have tried the following settings in about:config based on a few threads online:

accessibility.blockautorefresh

network.http.redirection-limit

A few other settings to that I have turned on and off but no difference.

A lot of the websites are also confusing because they seem to want to turn redirects ON rather than off, so potentially I am struggling to follow the correct information.

Any help appreciated.

Beginning today, I suddenly cannot access numerous websites when I use Mozilla Firefox 151.0.2. Examples include Amazon, and Google, et al. Attempts to do so consistently fail at the point of performing a TLS handshake, when I am advised that "secure connection failed". Kindly refer to the attached screenshots. I have no difficulty whatsoever accessing the same websites when I use other browsers, such as Google Chrome and MS Edge. I previously had Mozilla Firefox enabled as my default browser, but I have had to change this, given these "challenges". Please advise how I can fix this. Best regards and many thanks.

Current Setup: OS: Windows 11 Home (10.0.26200) Firefox Version: 151.0.2 (Build ID: 20260525130955)

Issue:

• Firefox suddenly is unable to connect to any wesbite
• All attempts to browse result in the "Secure Connection Failed" screen
• All other browsers function fine with no network connectivity issues

Exact Display Text:

Secure Connection Failed

The page you are trying to view cannot be shown because the authenticity of the received data could not be verified. What can you do about it?

The issue is most likely with the website, and there is nothing you can do to resolve it. You can notify the website’s administrator about the problem.

Attempted Fixes / Things Confirmed:

• Everything mentioned in: Firefox can't load websites but other browsers can

• Relevant about:config values:

* * security.enterprise_roots.enabled -> True

• * security.ssl.enable_ocsp_must_staple -> True
• * security.ssl.enable_ocsp_stapling -> True
• * security.tls.version.max -> 4
• * security.tls.version.min -> 3

• System locale and timezone are correct
• DNS over HTTPS is set to OFF
• HTTPS-Only Mode is set to Don't enable HTTPS-Only Mode
• Restarting in Troubleshooting Mode
• Disabling the Anti-Virus (including the device Firewall)
• Disabling any VPNs or network proxies
• Clearing cache and browsing history
• Clearing certificates from the Certificate Manager in Settings
• Attempting connection with a newly created profile
• Clearing the cert9.db file for Firefox to reset certificate information
• Refreshing Firefox (resetting it completely)
• Uninstalling and reinstalling Firefox (after clearing all Mozilla related %appdata% folders)

Observations

• When trying to mess with the device timezone and see if changing it back to the correct one would "reset" something, after a few attempts of starting Firefox in the wrong timezone and then restarting it after changing to the correct one, for a single session, I was able to browse normally again. I closed Firefox to see if the problem was fixed but it went back to the "Secure Connection Failed" page. Was unable to reproduce the same behavior.

• Tried installing a portable version of Firefox (151.0.3) from Firefox Portable .

After installation, the first session works perfectly fine but after I close the session and restart Firefox, it gives the same "Secure Connection Failed" message.

• * Reinstalling the portable version in the folder, gives the error from the get-go, not even the initial post-installation session works but installing in a different folder works fine for the first session but all subsequent restarts (sessions) of the browser give the same error.

Mozilla has been bragging about the free built-in Firefox VPN for months now. I still don't see it. I'm on the latest release (151.0.3) but I don't see any way to access it. I know they've said it would be a phased rollout but it's been a long time coming already. Am I doing somethin wrong?

I can not seem to find the button to open a saved, closed tab group. I have googled, and there seems to be a lot of people with the same issue. However, None of the information given under those forums provides me with a clear, easy solution. Please help.

Malwarebytes is picking up and blocking an outbound connection request from Firefox - www.highperformance.com. Anyone else experiencing this?

System Windows 11 - Firefox 151.0.3 All normal actions from mouse right click have disappeared eg open link in new tab or private window, copy, paste etc etc. The Settings General - Tabs has not changed and previously worked rt click ok. Any help to restore the rt click function will be appreciated.

Today following a brief power outage I was no longer able to sign in to AOL with Firefox on my desktop computer. I am able to sign in to all other apps with no problem. I tried clearing my cache, restarted Firefox, restarted my computer and spent 30 minutes on remote desktop access assistance with AOL trying to fix the problem with no success. I can log in to my account using Chrome on the desktop computer and can log in with no problem using my Android phone but can't log in using my desktop computer with Firefox. I've verified that my Firefox version is updated. I am running Windows 11 Pro.

I would greatly appreciate any helpful advice.

How can I log in to my firefox account to sync on my new PC if I can't verify the email address associated with my account? I no longer have access to that email because my employer phased it out.

Being a weird person, I always saved my sites on my firefox browser and for my own reasons, hadn't bookmarked them and always kept them open on tabs to pick up and read at a later date, and as a result, racked up a lot of different tabs that were all very dear to me. However due to a catastrophic hardware failure a few hours ago I lost everything on my local files, including my backups of all the firefox tabs. I was hoping that if there was a remote possiblility that if the sync was able to record tabs, that it would also save all tab information from previous browser sessions.
