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?

So I was downloading a video from a website and when I download it it says "Mp4 (1)/(2)/(3)..."in the notification but when the download finishes I can't find the file in the "downloads"section and when I find the file in the file manager it shows the file but when I click to open it it plays for a second or two then closes automatically

It's not the website's or the files fault since I can download the same file on chrome

Since the new Chrome changes I have tried to switch from Chrome to Firefox but this download problem is the only thing that's bugging me and keeping me from using Firefox as my default browser

Please if anyone has a solution to my problem, it is greatly appreciated

I have recently installed Linux Mint and it came with Firefox out of the box, and I decided to try it out, but I can't, for the life of me find a way to transfer my Opera passwords there. I do have Opera installed right now.

I've read the forums, i've tried adjustments for days on Win 11 and firefox. Zoomed in zoomed out, adjust font sizes Either it's way too tiny to read or the page is fine but text over laps i've tried the zoom in on text only as well Basically tried everything. enclosing a youtube page for reference

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

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.

I'm currently attempting to try out userChrome.css customization, but my profiles folder doesn't exist (I'm on windows 10). Trying to open the folder gets me the message that "[Folder name] is unavailable," and when I try to navigate there by getting to the appdata\roaming folder, there just isn't a Mozilla folder at all.

I've already tried a few things, specifically:

- making an account via typing firefox.eve -p into the windows + r folder
- I've never deleted anything from the appdata roaming folder, so I wouldn't have accidentally deleted it
- restarting my computer (+ updating windows)
- reinstalling firefox

I did attempt to show hidden file extensions in windows as well. Admittedly I'm not entirely sure if that worked, but it was something I tried. I've also attached images of my appdata roaming folder (the section of it which should have a mozilla folder), and a pic of the message I get when I try to open the folder.

Any help would be appreciated!

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.

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.

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.

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

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?

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! :(

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?

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.

Greetings!

I would like to be able to open selected links via the search tool with CTRL + Enter, like it is possible on most browsers. Basically, I do CTRL + F, select a text which brings me to a link I was looking for, and do instantly CTRL + Enter to open this link. Currently, this shortcut only toggles the ability to see all matched texts and doesn't open the link.

Do you know if it's possible? Thank you!

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
