When I play YouTube videos in Firefox, the video stutters and drops frames, even at 480p. Audio keeps playing normally. This does not happen in Chrome on the same computer. The issue started about a week ago. I’m using Firefox on Windows 11 on a laptop. Restarting Firefox did not fix it.

Yahoo Mail settings. When I use Yahoo Mail with Thunderbird for Android, the folder structure is displayed in English. I want everything to be shown in German. Everything works correctly with Gmail; this is only a problem with Yahoo Mail. I've set everything to German in my Yahoo account, but it's still displayed in English in the app.

What can I do?

Hi, I'm on Debian. In the last day I have intermittent connection problems on many websites which go away after a while. Any ideas? I'm using Quad9 for DNS but I don't know where in the chain something is going wrong

Firefox iOS updated this morning to 143.1 In private browsing it’s in dark mode automatically and won’t change even if changing to light in the settings.

Any help? Steve

MB is telling me to put MB on Firefox! BUT, I already have MB on Firefox. Can you help me.

Thank you,

I have Firefox installed on three Windows Desktop Computers. On one, I just cannot delete Bookmarks, no matter what suggestions I try. Verify Integrity of the database produced no results. I do not, for a variety of reasons, sync bookmarks (or anything else) between the three installations. Experienced user that has spent far too long on what should be a simple issue.

I'm simply trying to email someone using the email link on their site.

The link is a mailto link which requires an email application (which I don't have). All I want is to copy the link to the clipboard.

Firefox lets me right click the link and copy the email address, but this doesn't allow me to provide the required Subject specified by the site's author.

I could have sworn Firefox used to have this feature. Netscape and IE certainly always had it back in the day.

Dear Helper,

since the newest Firefox update, i got today (16.09.25), the audible cloudplayer doesnt work anymore, meaning it wont load the audiobook! I emptied the cache, but nothing changed. I tried the audible cloudplayer with Windows Edge and it works fine, so it is a Firefox specific problem. I granted all websides access to audio and media automatic replay, nothing changed. The cloudplayer doesnt work! So my question is: What else is interfering in Firefox with the loading of the player? Thank you so much in advance for your help :) Yours sincerely David

Hi,

Looking at my Firefox 147.0.1 settings for macOS 26.2 (Apple M1), I'm trying to adjust two settings:

-- I'd like to remove Languages -> English (GB) (its existence has odd side effects, like triggering United Airlines to offer fares in Pounds Sterling, and I'd prefer to just have English (US))

-- I'd like to disable Play Audio and Video for about:welcome (in regular and private windows)

I can see no way to accomplish this currently -- why?

Thanks.

I have Thunderbird desktop. I love it! I recently downloaded Thunderbird mobile. I'm having a problem syncing them. My personal folders don't show on Thunderbird mobile. Please help!

I recently went back from Thunderbird daily to the release channel when I set up my new PC.

1. On opening an email - The Subject display in Daily Version is Bold and according to the font as set in Thunderbird Settings. Just Perfect. It is not the same in the Release Channel. Looks not so nice.

2. In Release Channel -- under settings If I choose to display the "Name Only" under Message List for address display format. It ignores

3. Release channel is ver 146.0.1 .. If I go back to Thunderbird daily .. will I be able to use the same profile used for the Release channel?

With my thanks in advance

Hello, for some time now, firefox focus is unable to load the x.com homepage; the app instantly tries to launch the X app. A provate tab in Firefox does NOT have the same issue. Please help and consider me available if you need to investigate further. Many thanks Alberto
