On Ununtu 24.04 I did an update and youtube doesn't work on FIrefox 152.0.4. I did an update from the Software updater and videos don't play on youtube any more. I go to youtube, click on a suggested video and it goes to that page and everything shows up except the video window. I have the title and the comments and the row of suggested videos on the right, but no video player and no video. Someone suggested I push the F12 key and look under console and there is an error there, a sourcemap error and that it isn't a valid URL . I don't know what that means. I asked on the AskUbuntu site but they get really far down in the weeds and I have no idea what they are asking or saying. I thought I'd see if you guys might know. thanks

I'm writing a home-grown email client (Python email module, yay!), and I've received an email with a couple of images with Content-ID: fields. Sure enough, the HTML bears corresponding URLS with cid: schema. Where do I put those image files so FireFox can read them, and when I run FIreFox, how do I tell it where those files are?I'm writing a home-grown email client (Python email module, yay!), and I've received an email with a couple of images with Content-ID: fields.

I have just moved from an old laptop to a newer one - a Lenovo Thinkpad. I have installed Linux Mint and successfully transferred my files and Thunderbird. I also synchronized Firefox and all my add-ons, bookmarks and history came across perfectly. While setting up the toolbar from the customise screen I dragged the home page button onto the toolbar and it just disappeared. The home page is set up in settings. It appears the first time I open a window. I would like to be able to go back to my home page at will, how can I re-instate the home page button?

I am using Firefox on Linux Ubuntu 26.04. I normally work with multiple tabs. Then I quit Firefox with all tabs open at the point of quitting. Some times on the rare occasion there can be a forced quit due to some issues. In my settings I have configured it not to open the previous tabs. In fact I want a blank page. But whenever I reopen Firefox, it opens those tabs and tries to reload which is annoying. Some of these pages take a long time to reload, and why would I want to look at tabs which I already have read. Or if it crashes due to some website on a tab why reopen something that crashed in the place ? Can you fix this. Thanks.

Cannot log on to synology when I have been logging on many times before now your browser says Unable to connect. I will need to change browsers if I do not get a response.

I have already turned off the 3 or 4 different types of firefox suggestions in the settings. Did they add yet another one? I can't find anything about it in the settings. How can I be sure I never get a pop-up suggesting any sort of wallpaper again?

I have a 100% repro rate of Firefox redirecting linkedin.com to linkedin.cn. Unfortunately there's another problem beyond the unwanted redirection: linkedin.cn no longer exits, it has been dead for years, I literally cannot reach LinkedIn at all. It was working fine a week or two ago. How do I prevent Firefox from redirecting behind my back? I see the status message (is that what it's called) in the lower left corner "Performing TLS handshake to www.linkedin.cn" and of course it only times out. I just verified with "Web" (different browser), it connects just fine, which suggests that it's a Firefox issue, not a system wide one.

The new "Copy Link to Highlight" button shifted the "search with" option down, which I use regularly.

I'm not entirely sure what the new option does, but I would like to either disable it or shift it further down out of the way
