When opening an email with an attachment (either a pdf or picture) in Yahoo mail, the Yahoo mail tab closes and I have to then reopen it from History, Recently Closed Windows. It's been dong this for some time now. Does anyone know how to fix this?

I am able to find the mailto setting easily. However, there are no clients listed to choose from, no gmail, yahoo, nothing. If I click "choose other" I'm expected to choose an application from my computer. I just want to be able to click a mailto link and have it go out through a new tab via my existing, free, yahoo mail account.

Since Firefox for Windows upgraded to 105 the Wordle web site fails to work - it displays the grid at the bottom of the window with no scroll possibility & it displays that even when a correctly working browser displays my statistics.

The website works correctly on other browser (Chrome & Edge), on Firefox for Android and on Firefox for Windows 104 (luckily I had a machine which hadn't been on for a few weeks and therefore was no up to date).

The attached images show the website as it should be (on Chrome) and as it appears on Firefox 105

Amazon Sign-in problem started on 10-15-22. Amazon does not accept my password and asks me if I would like to receive a text message for verification. There is no yes or no selection displayed. I select resend text and I am given a telephone number for Amazon customer service. I go thru a 15 minute security verification process and Amazon tells me if I do not answer any questions correctly, they will cancel my account. On the 2nd time I contacted Amazon, I was told to use Crome browser and not to use Firefox.

This problem happens with my personal computer (windows 10) only. My Android phone using the Amazon app works with no problems. I can also use Crome browser on my computer and Amazon works fine.

Any suggestions ? Thanks

I told Firefox to never remember a website login user/pass but now want to revert this. I have looked for this option but can only find the remembered user/pass. There is an option at the bottom of the chrome password list, but not in firefox.

Can someone please point me to the area that i can remove this "never remember logins for this site"

Thanks in advance

I want to disable ad blocker. I actually want to see the ads. Since I did the latest update, ad blocker is turned on, and there appears to be no way to turn it off. How do I disable it?

In the past, I have not had problems logging into PayPal via Firefox on Windows.

Today, I can get to www.paypal.com but when I try to log in (takes me to https://www.paypal.com/us/signin), my browser window just shows the circling image.

When I tried another browser (Chrome) I got to the login just fine. My Firefox is up to date (105.0.3)

What changed to give this issue and how can one resolve it?

When I go to https://outlook.live.com/owa/ and click on Sign In, I am sent to https://login.live.com/login.srf?wa=wsignin1.0&rpsnv=13&ct=1664586249&rver=7.0.6737.0&wp=MBI_SSL&wreply=https%3a%2f%2foutlook.live.com%2fowa%2f%3fnlp%3d1%26RpsCsrfState%3d17ece2a1-03ee-4d23-1804-181c6fe01157&id=292841&aadredir=1&CBCXT=out&lw=1&fl=dob%2cflname%2cwld&cobrandid=90015 which stays blank instead of bringing up the Sign In form. I've tried deleting the cookies to no avail. I've tried Troubleshooting Mode to no avail. It's been this way for a couple of months now. I have no trouble signing on to Outlook.com using other browsers.

When expanding any video to full screen mode, the video does not occupy the entire screen. However, if Firefox itself is in full screen mode, then the video will occupy the full screen.

I tested this on YouTube and another website's video player and was able to consistently replicate the issue.

Hi Firefox community,

Do we have any settings in firefox where we can enable/disable dark mode in firefox browser instead of installing a plugin or addon? I am looking something that is offered within the browser instead of a plugin.

Thank you all.

HELLO very small cursor on Firefox windows (on all other windows the cursor size is normal) via snap after upgrading to ubuntu 22.04.1 LTS. how can i change it? Thank you

Recently, I've started noticing these quick action tiles in the URL drop-down menu (I've attached a screenshot). There's a help icon to their right, but it just goes to https://support.mozilla.org/en-US/kb/quick-actions-firefox-search-bar?as=u&utm_source=inproduct which is a 404. I found this bugzilla bug, but I'm not 100% sure on how the versioning works (even after consulting Wikipedia). The bugzilla entry mentions it's fixed on 105.0a1. I'm using 105.0b6 of the Developer Edition.

OK, I have read (ad nauseum) every Fix to not getting sound while using Firefox. I disabled Hardware accelerated Graphics, Cleared cache, cleared history, disabled all addons, updated Firefox, uninstalled and reinstalled Firefox, etc. Nothing has brought the sound back.

I have sound on my computer and on games and in Google Chrome and Microsoft Edge but not Firefox. Anyone know something that I may be missing? PLEASE HELP! I wish Mozilla had Tech Support! :(

While exploring about pages in Firefox, I came across about:profiling. I'm not sure what exactly it does, but since I've been to it, a profiler icon has been added to the toolbar and I can't find any way to get rid of it completely (only ways are to hide it). If it could be added, there must also be a way to remove it? How can I close it?

Hello. My Windows 10 suddenly crashed, so I reinstalled on a new hard drive, with the latest version of Firefox. My old Firefox, was completely up to date but still used the Key3.db file for my saved logins, and it will not work with the newest version. I tried creating a new profile and pasting the logins.json and key3.db files, as suggested by an old Firefox KB article, but that doesn't work any more. Is there any way for me to get the saved logins out of the older JSON file with the Key3 file? I desperately need help with this, and would appreciate any that someone could give.

Regards, Brian Mercer.

The Aer LIngus website crashed earlier this month, but was reinstated shortly afterwards. But I am still unable to see it on Firefox, though have no problem on Opera. I get a message on Firefox: "To regain access, please make sure that cookies and JavaScript are enabled before reloading the page". But I didn't make make any changes to my Firefox settings so am at a loss. Help! Thanks.

So this problem is isolated with Firefox as it doesn't happen with Edge or VLC on this pc. If I have Twitch or Youtube, probably any other audio or video playing, open when I turn the monitor off the audio will no longer go through properly when it is turned back on. The video is still playing fine but the audio isn't going through properly. Refreshing the page fixes the issue.

I have made sure to disable all other audio outputs and defaulted the current HDMI output. Audio playback works fine on every other application that I have tried.

Running Windows 11.
