I've tried deleting all history, cache settings. Deleting and reinstalling Firefox. Backing up existing profiles and restarting. NOTHING except starting in Troubleshoot (Safe) mode makes a difference:

I use Yahoo mail from my Firefox browser (mail.yahoo.com). Today Firefox won't let me begin a new email. I click the "compose" button, which should open a new blank email, but nothing happens. I tried in Safari and I can do it there. Please advise and thanks for your help.

In the Microsoft Store there are all these updates for video extensions like "AV1 Video Extension". Should I be doing these updates? Do they make any difference to streaming video on the Firefox Browser?

Hello, when initiating a request for conditional mediation with webauthn I get the following error:

TypeError: 'conditional' (value of mediation) is not a valid value for enumeration CredentialMediationRequirement.

However when asking whether it's available with `await window.PublicKeyCredential.isConditionalMediationAvailable()` it does return true. Is this a bug?

Is it to possible to set Firefox to use a 2.2 gamma instead of the sRGB piecewise function, when enabling color management?

In case this is not possible, could the devs please consider adding this option? SRGB piecewise function is not appropriate for LCD displays with contrast ratios below 2000:1.

I don't want want Firefox to add itself as a right click option open JPG's on windows 10 open with menu. I go to regedit and delete it but some how it is back in the open with list again.

Hi there, I got the following virus alert from McAfee after doing a quick scan: JTI/Suspect.196612!0f6afa0fe6d5

FileLocation: C:\program files\Mozilla Firefox\AccessibleMarshal.ddl

I then completely uninstalled Mozilla Firefox from my computer including all data etc. . I then did another scan and there was no virus alert. So I then reinstalled Firefox and did another scan and I got the same virus alert as above. I then uninstalled Firefox again and once again when I scanned the computer there was no virus alert.

I have been chatting with mcafee support and they said the .ddl file has a vulnerability. do you know anything about this?

When clicking a web link from the "Finder" (and Firefox is inactive/closed) a blank google search page opens. If Firefox is already open the desired link will open

A browser hijacker malware (www.discoverresultsfast.com) was installed on my MacBook Pro OS Ventura, 13.6 FireFox Browser 115.3.7 ESR without my knowledge and is bombarding me with notifications. Would you have a method to remove this? Thank you, Falcon [email removed from public]

I have macbook. When I open a puzzle e.g. sudoku, the puzzle costantly jiggles about (which I have video of). When same puzzle is opened in PC, ipad or Safari this doesn't happen. Why?

Firefox for MacOS will not accept my new Primary Password - the exact same password that Firefox on my iPhone & iPad did accept! Firefox for MacOS keeps telling me the password is incorrect. I am using MacOS Ventura 13.5.2 & Firefox 117.0.1 (64-bit).

I want to use my tablet for writing/drawing on some websites but the browser doesn't recognize the device. It computes the mouse on the "drawing" screen but not the tablet, and also computes using the pen for clicking and dragging, and/or the tablet as a touch-pad. The device works fine on chrome and on my drawing softwares, so it isn't a problem with the pressure sensors or driver. Tested disabling all addons and restarting Mozilla, but the problem remains. Mozilla is up to date, and I use W10 (also up to date).

Any advice?
