Firefox Community Forum

Recently I’ve been unable to play YouTube videos on Firefox: “Video unavailable.”

I’ve tried clearing the cache and cookies, and restarting Firefox in safe mode. I’ve disabled “Use recommended performance settings” and “Use hardware acceleration.” Still no videos.

I’m using a VPN and have several Ff extensions - none of them video related.

The problem seemed to start after the most recent Firefox update. YouTube works fine in Safari.

Thoughts?

I have searched these forums for "always on top" and the results were completely useless, so I assume no one has asked this question before, or the search engine is ineffective.. anyway, the question is:

When watching a video where you can click the right-side button to pop the video out to Picture-in-Picture mode, the video window that pops out is permanently set to Always On Top. It is often inconvenient for it to be Always On Top. I would like to be able to right-click on that video window and be able to select an option to disable Always On Top, or failing that, I would like to be able to disable this Always On Top via manually setting something in about:config. Can anyone recommend a solution that doesn't involve installing any third-party software to control Always on Top behavior? Thank you in advance.

Until the most recent update, when I opened a new tab a box with the message "Search the web" appeared, and I could enter a query to search. This was exactly what I wanted. Now, the box still appears, but as soon as I type a character the input jumps to the small box at the top left where I would expect to enter a URL. I don't like this, because (a) the jump is disconcerting when I'm trying to type, (b) I want what I type in the URL box to be always taken as a URL, not as a search query, (c) the box in the middle of the new tab is just a waste of space: something held out then snatched away. The solution I have found suggested is to set the resource browser.newtabpage.activity-stream.improvesearch.handoffToAwesomebar to false, but this causes an error message to appear in the search box. I'm sure there must be a way to have the old behaviour back - any help gratefully received.

Updated and lost everything in my browser and now is complete crap, no bookmarks, and it install google as a search engine that doesn't work. Can you help me rollback to the version that worked just fine? Searched help and didn't find a way to resolve problem.

Thank You,

James Johnson

Hello,

I am experiencing an issue with Firefox where some websites display a message saying that the internet connection cannot be established and that I am offline, even though I am connected to the internet.

My internet connection is working normally. Other websites load without problems, and the same websites also work correctly in other browsers such as Google Chrome.

However, in Firefox certain sites do not load. For example, YouTube and YouTube Music show an error message indicating that I am offline. I have also noticed this issue on a few other websites.

Because the same pages work normally in other browsers, it seems to be related specifically to Firefox.

Could you please help me understand what might be causing this issue or how I can fix it?

Thank you.

Is there anyway in the setting to stop a shortcut from being added every time I visit a site? I only want sortcuts that I use. I have attached a screenshot circling the ones that keep popping up as an example.

Respectfully, Rhonda

Hello!

I first installed Video Download Helper several weeks ago and it worked fine. However, since the update of 04 March, 2026, it no longer works with YouTube. (It does, however, still work with Instagram.) Having checked all of the settings (which I had/have not changed), I uninstalled it today and then re-installed it. This hasn't helped. With YouTube, the Downloader icon (pinned to toolbar) simply remains grey and does not show any videos when opened. I am using the latest, fully updated version of Firefox with Windows 10.

Can anyone help, please?

Many thanks,

Stuart.

I use Firefox on a Mac to access Brightspace for my classes. I also use Grammarly. When copying text from the Grammarly widgets and pasting it into the Brightspace HTML editor, the text is stripped of hard returns, causing paragraphs to collapse without any breaks between them.

I have tried pasting as unformatted text, and the issue persists. This issue does not occur in Chrome, so I suspect it is due to how Firefox handles clipboard data. I have not found a workaround or resolution for this.

Topic is Extensions. How do we get an extension to be recommended by Mozilla? Maybe we can upvote to do this.

"Gmail Conversation Reversal" - likely the first one with the most reviews and most recently updated. SS attached.
