My browser has been acting off lately, it takes a longer amount of time than usual to even open gmail. Sometimes, it just fails to connect to a server and keeps loading forever and just stops (including gmail).

Went to https://www.universalproperty.com Received error: “An internal error occurred!” Please see the console for more details.

Hello, I run a movie and drama-related website: https://tvmon.com.co/. Recently, I’ve noticed that Firefox occasionally throws the following error when trying to access the site:

"Secure Connection Failed An error occurred during a connection to tvmon.com.co. . The OCSP response contains an invalid signing certificate. Error code: SEC_ERROR_OCSP_INVALID_SIGNING_CERT"

This issue is very strange because:

1. The site loads fine in Chrome, Edge, and Safari.

1. My SSL/TLS certificate is valid, up-to-date, and passes external tests (SSL Labs, etc.).

1. The error only appears occasionally in Firefox, refreshing sometimes fixes it, sometimes not.

1. Hosting and server logs show no issues at all.

I suspect this is related to Firefox’s stricter OCSP validation, but I’m not sure how to debug or resolve it. Since my site streams drama and movie content, this error is frustrating for users who rely on Firefox.

Has anyone else experienced this intermittent OCSP signing certificate error? Is there a known fix or workaround for Firefox-specific validation issues?

Despite having the setting "Ctrl+Tab cycles through tabs in recently used order" selected, CTRL-Tab has suddenly stopped cycling tabs in the most recently used order. Firefox behaves as if the setting is disabled. This is the third time I've experienced this issue in the past year, and every time the only solution that worked was to create a new profile. It is exhausting to get a new profile back to exactly how the old profile was, and it's something I shouldn't have to do.

Scenario: I am on Windows 11 (though I think this has also happened to me on Windows 10), currently using version 146.0.1 (though this has happened on previous versions). CTRL-Tab cycles in the most recently used order just fine for several months, then it suddenly doesn't—this happens in the middle of an active session, i.e., not after a restart of the browser nor the computer itself. I have four add-ons, none of which control tab cycling, nor have I added/removed any add-ons nor changed any of their settings since their initial installation many months ago.

What I've tried:

• Disabling/re-enabling the setting (even though it is already checked)
• Disabling/re-enabling the config browser.ctrlTab.sortByRecentlyUsed
• Restarting Firefox normally
• Restarting with add-ons disabled—note that the issue persists even with add-ons disabled
• Disabling the setting, then restarting Firefox, then re-enabling the setting
• Restarting the computer

It's the same thing described in this Reddit thread. What else can I try?

A leak was detected on my account then Mozilla locked it. Every passwords were changed as I still got an "Email just returned" error upon trying to sign in, and now I end up with an "Unexpected error".

And to make sure that this has nothing to do with the plugins I have on my pc installation, I tried signing in on mobile phone as well. Same issue.

I have autofill turned on, and it works (almost). The address fields are completed, but left in yellow highlight, and when I try to submit the form, it isn't accepted. I have to manually enter and then delete a character for they yellow highlight to clear - and then the form submission works. It's happening with more sites now.

Is there a solution?

Hello,

I'm trying to access a dropdown menu on trafficjunky.com but the menu is not functioning correctly and will not load. When I select the dropdown, it opens a small blank white box that should fill with options, and I should have the ability to free type as well so I can search for a location. This does not happen, the only thing that happens is what you can see in the picture and free type is not functioning.

I have cleared cookies and cache numerous times, updated my browser, deactivated extensions, turned off performance settings, and have tried both troubleshooting and incognito modes as well. I am not running ad blockers or themes on Firefox.

Any advice you can provide is appreciated!

Thank you, Kyle

Through extensive troubleshooting, I am unable to get firefox to open at all.

I've done a full uninstall, cleaned all user directories, program files / x86, program data, appdata roaming and local, etc. I used the Microsoft uninstaller and even Revo Uninstaller to remove everything related to Firefox, did a restart and reinstall of the latest one and it still won't launch.

Firefox was previously working until a reboot occurred and now it won't launch.

Firefox 32 bit seems to work when installed, and running Firefox as an admin previously worked but no it no longer does.

I looked at the following articles: - https://support.mozilla.org/en-US/kb/firefox-wont-start-find-solutions - https://support.mozilla.org/en-US/kb/profile-manager-create-remove-switch-firefox-profiles - https://support.mozilla.org/en-US/kb/profile-manager-create-remove-switch-firefox-profiles#w_start-the-profile-manager-when-firefox-is-closed

There's no malware on this machine (business EDR on it, even disabled it as a test and it still didn't open).

I was able to launch the profile manager but now I am unable to as the processes launch in task manager and then within 5 seconds they close.

Firefox is not running in the background for any user (I'm the only one logged in after a reboot as well)

I'm unable to open in troubleshoot mode either. Tried run as and admin cmd "C:\Program Files\Mozilla Firefox\firefox.exe" -safe-mode

Ran SFC / scannow / DISM restore health commands as well and both came back fine / no integrity violations

Good afternoon. When I try to send an email link from the Firefox the default comes up with the "New Outlook." I would like to use Outlook Classic as I have in the past. In your default there is now way to choose Outlook Classic only the "New Outlook." Is there a work-around to this. Thank you!

bold textSelected text on page, e.g. search terms, are a dark grey color with black text. I have changed every option on setting with no success. I don't seem to be able to specify the highlight. I have tried, I tried overriding web pages to use my settings, high contrast, and system colors (PC, Win 11). This also occurs in eb pages, e.g. the Amazon page.

Thanks Mike

In the Security Measures overview, under Manage Passwords, I see the following: 3 passwords may have been exposed through data breaches.

All 3 websites with data breaches belong to Facebook.

I permanently deleted all Facebook accounts more than 3 years ago.

Without Facebook accounts, I can't and don't need to change my passwords, right?

Thanks and regards
