Firefox Community Forum

Hello, Mozilla. I really appreciate the way you think about internet access. What you stated about the app is truly reflected within it: fast connections, accurate results, and most importantly, the security. However, when it comes to advertisements, I was really expecting that whenever I watch YouTube contents, there will be no ads shown. To my surprise, ads are still there. I provided a snapshot of my desktop to give a proof about this. Is there somehow a way to get rid of them, like perhaps an extension to block ads? If there's none, that's fine as well. Thank you and high praise to the developers of this browser.

on other webpages a black bar drops down from the bookmarks bar and blocks the top of the pages, how do i get rid of it? oddly on this page, the bar does not show up

Hello,

I've been using the profile manager, and wanted to delete a profile that i have made. However, when i select the option to delete it, it only opens up a new tab in the profile called "about:deleteprofile', which displays an empty page and does nothing. Then, I would try to delete the profile manually, in the profiles folder, but if I opened firefox or restarted my computer, it would just come back. I have attatched the relevant images below.

There is an issue with MKV video playback with MP3 audio track in FireFox. The problem is that MKV video plays MP3 audio track without any sound. With AAC audio track the problem is that MKV video initially downloads whole video and only then plays it. In comparison with MP3 and AAC the benefit of MP3 is much better quality and it starts playing without downloading whole video like MP4.

It would be nice if you add support MKV video with MP3 audio playback.

I have enabled the option to open the previous windows and tabs. I had one window that I always closed last as it had a lot of groups that are important for my work, so it used to open every time I started Firefox. Sometimes, even if I closed the window by mistake without closing other windows, I was able to get it back by pressing ctrl+shift+n.

But yesterday, I might have closed it by mistake and when I pressed ctrl+shift+n , it didn't come back. I wasn't able to access my window and now it's all gone. I don't see anything in recently closed windows in history.

I need those tabs back as they are very important for my work. they were a lot of tabs. I had many groups but now all are gone. I tried by using the previous.jsonlz4 in the sessionstore-backup by renaming it in the default-release profile as sesstionstore.jsonlz4 but still wasn't able to access my window.

I didn't clear my history as the tabs opened in the window still show up in the history.

Kindly help as soon as possible

Hello and good afternoon. I have a problem with my last session as it doesn't appear, even when I try to do it manually in Settings-History-Import and backup-Restore, it shows me some options of different dates with all my last browser history, but none of them works, it simply doesn't open any of the web pages. I don't have any other profile, and I already tried the troubleshooting too I Hope you can help me. Thanks in advance

I want to disable AI on Firefox. I noted a response to another request, that in the first quarter of 2026 something will/may be introduced to allow users to choose not to have an AI input on their Firefox. When will this be available?

I can see why AI summaries on Google searches can sometimes be useful. But I don't have any need for AI-related things on my browser and certainly don't want to contribute to AI's impact on resources etc.

It should be a simple yes/no choice. If it's too complicated to provide a yes/no choice that itself is a very strong indication that there's good reason for needing that choice. What is happening, and when?

Last week I went through the process of choosing a profile so I would not be faced with choosing whenever firefox opened. ( I was guided through the process by some of you elders.) My bookmarks are all in place but that history no longer accumulates, not even during the session I am in. I must have hit something without knowing it. I have gone up and down settings on several levels, but I can't figure out what will make this work again. It is helpful to have this reference so I would appreciate help. Gratefully, Marjorie Kinsey

Dear all,

for two days (as of march 21) any search request is denied, no results are despayed. Instead a message window pops up: "Error: Routing error", the requested website (here: duckduckgo.com) would send the request into an endless loop. This problem only occurs using the mac-version of FF 148.02. The moblile version runs as normal, and another browser, Safari, works as he should.

I tested all my add-ins (switching off and on), private mode produces the same result. So, could you give a hint, is it (my) single, private issue?

Thanks a lot, this cuts me off the internet at large.

The method of putting an older jsonlz4 and naming it sessionstore. It's not working. I've also tried session history scrounger and it's just saying "session history file contents couldn't be read". Any ideas, I've lost a LOT of tabs to it forgetting the previous session.

I've tried all files from the session backup folder including the update backups and I used shadowexplorer to get my session files from the 18th.
