i can change font size in general via firefox settings, BUT!

whenever i want to download a file from any given website,
the download window that appears, in which i can navigate to a folder on my computer and choose a name for the file,

has such super small font!!! and to make it worse, the text largely in a soft gray rather than a nice strong black! SO hard to read. i would love an easy way to make this font always bigger for all these situations. if anyone can provide the solution im super grateful!

I have noticed recently that when i try to play certain videos i am sent that are embedded on webpages the screen just goes black and i cannot see anything but i can still hear the video playing in the background. Why is this happening. I have a new HP envy laptop and am using firefox browser but when i use my work laptop which does not have firefox (IBM Thinkpad) i do not face this issue therefore i assume it is a setting in firefox

I can open pages but when I click on the subject it doesn't open. Tells error with net work connection, it's like this with email,YouTube and Gmail, twitter. Thank you.

Two websites I went to using Firefox today displayed the date as 6\18\2025. Today is 6\19\2025. One of them displayed the July 2025 calendar and would not allow me to click back to June. I have two Firefox Extensions on, UBlock Original and Chameleon. Any idea what may be causing this. I'm using a MAC.

For some reason Firefox remembered my phone number and is now trying to use it as a login when I attempt to login or register in any service. I've checked my saved passwords and autofill data, but I cannot find it, there's only usernames and passwords, and I have no saved autofill data, no phone number. Where can I look for it to remove it?

Good morning from germany,

I am a multiple year subscriber and wanted to watch game 6 before going to work (it is around 6 am over here) but the player isn´t running and it states that games can not be played, even the recap doesn´t start. Other videos are running as on youtube and other social networks. I switched a VPN from location germany to location USA to off but nothing works. I am using the newest version of mozilla firefox.

Can you give me some help what I can watch in order to watch the last two Finals games as well?

Thx guys

Hello, using Windows 10 Version 22H2 (Build 19045.5965), Firefox 139.0.4, Thunderbird 139.0.2, I can drag multiple emails from Thunderbird but not drop them into Firefox (the stop symbol appears and does not let me finish the action). However, dragging and dropping single emails does work. Firefox does not understand the imap address but the drop is registered which is all that is relevant to me. Is this a bug/missing feature in Firefox or a problem with Thunderbird and Firefox on Windows? Or is there a way to do it by simply adjusting (preferrably very few) settings? Dragging and dropping multiple emails using Thunderbird and Firefox on Linux Mint works fine. Dragging and dropping multiple emails from the Windows Explorer to Firefox also works fine. In testing, the issue only arose using Thunderbird + Firefox, Chromium-based browsers also worked fine with Thunderbird. If this is the wrong forum to ask such a question because this should rather be in a bug tracker or something similar, please let me know. If this should be on the Thunderbird thread instead of Firefox, also let me know. Thank you for your help.

On certain websites , the audio and video still auto play even though the option, "AutoPlay" is blocked for both audio and video.

Please see the attached screenshot which shows that auto play is blocked, it is circled in red. While the video has auto played, circled in orange with a timestamp of 17 seconds being played prior to it being manually stopped.

Please fix this issue.

After last upgrade, I restored an earlier profile to RESTORE my bookmarks and passwords.

I set my old profile as DEFAULT.

YET NOW, I have the highly annoying problem that when I open a link from my email, it opens in the profile-release new version.... I then again do not have access to passwords and bookmarks.

Mozilla Firefox should address these issues, rather than have MILLIONS of people individually trying to fix the problems that the latest release caused.

I'm afraid to close my browser windows or even restart PC like I often do; I'm afraid I'll have to waste another 6 hours (like yesterday) trying to restore the profile, bookmarks and passwords.

This problem just began today on my Win 11 laptop. Firefox is current - 139.0.4. Win 11 is current. No new software has been installed. Firefox hangs up and will not move. Task manager shows FF is consuming more than 90% of my 16GB memory. I must end the FF task to get up and running again.
