Firefox Community Forum

Just wanted to ask about the potential for other Ai providers--Duck.ai being the key one missing.

Is there a possibility of local instances being a feature? Whether it's just hosted locally (not a function or component of Firefox itself) or a Mozilla specific model that's locally run?

I was using Firefox just fine during the day. My laptop switched off with Firefox still open (was simply doing sth else). When I switched my laptop back on and opened Firefox I was signed out of my account. When I signed back in all my profiles and bookmarks were gone. Is there anyway to fix this issue?

I'm trying to diagnose an unusual problem on a relative's computer elsewhere in the country via TeamViewer. When Firefox is initiated, the same picture (a man taking a shower) appears, and the VERY 'long URL starts with a Yahoo image file (yimg) and also contains buzzfeed.com well into that URL. I thought I could easily diagnose this, and have failed. Home page is set to blank page. I cleared all browsing data. When that failed I exported bookmarks, created a new profile, and the problem still continued, even before importing the bookmarks or adding any extensions. Something is retaining the unwanted startup behavior. Tonight, out of desperation, I will reconnect and look through the registry.

Can anyone surmise why an unwanted URL is being invoked upon Firefox startup?

The same thing happens on my two Dell laptops (Inspiron and Latitude), and a Hyper-V VM (on my desktop PC). They all run Bazzite Linux 6.17.7-ba25.fc43.x86_64.

A video may play for a second or two, and then it's either a black screen, or an error message of "The content doesn't seem to be working."

On the same two laptops and VM, the Chromium Browser, and LibreWolf (a fork of Firefox?), have no issues playing the same videos.

Firefox version on all three systems is 147.0.3.

Any help/guidance welcome with thanks.

I get three grey boxes at the top right of the Firefox start-up page. See the attached image. They dissappear if I search and enter another web page. The only way I can get rid of them is to reset Firefox. They return within 24 hours.

What are they and how can I get rid of them?

Hi

I have tried to launch Firefox a number of times today and every time it has frozen and does not respond. When trying to select the option of opening the software in Troubleshoot mode, once again the software freezes and I am unable to open the software in Troubleshoot mode . I have tried shutting and re-opening both the software and my laptop but this does not resolve the issue. Can you please either resolve the issue of the software freezing or tell me how I can resolve the issue.

I have updated today 2-7-2026 Read Aloud on Windows 11. It said I needed to allow permissions on 3 things. 2 of those things on the same page had slider controls for permission which I turned on. The 3rd thing is not present. It is supertonic.ttstool.com

I want to make sure my new update to Read Aloud will continue to work well. I have low vision and use this add-on a lot.

I'd like to know how to check that Read Aloud has the permission it needs for supertonic.ttstool.com

I can't pull up the original screen or I'd tell you what the other two were. One I think had to do with permission while navigating.

Thanks.

I have Norton 360. I just reinstalled a brother printer and now I get the "Your browser is being managed by your organization". While I sync with my laptop, as others have said, I'm not an organization. There is an Enterprise policy .

Active Policy Name Policy Value ExtensionSettings {"firefoxhpsureclicksecurebrowsing@bromium.com":{"installation_mode":"blocked"},"firefoxhpwolfsecurityextension@bromium.com":{"install_url":"https://addons.bromium-online.com/wsx.xpi","installation_mode":"normal_installed"}}

I can't store or edit any bookmarks. How do I correct this? I need answers in very simple terms as I am very much a layman with computers. Thank You!

I set up my new tab (after the Home page which was Google News for my profile) to show shortcuts in four rows. Clicking on these shortcuts opened the URL for an account or webpage. I "pinned" or "dismissed' these shortcuts over time. Somehow, I lost every shortcut and cannot seem to figure out how to recreate this.

Hi everyone,

I’ve been using Firefox as my primary browser and overall it works great, but I’ve noticed a slowdown pattern during longer sessions and wanted to compare notes with the community.

After running the browser for several hours with many tabs open, I sometimes see delayed responses when switching tabs, typing in text fields, or opening menus. Nothing crashes, but the interface feels heavier until I restart the browser. Once restarted, performance goes back to normal.

I’ve already tried reviewing extensions, disabling a few that I don’t use often, and checking memory usage in about:performance. The numbers go up as expected with more tabs, but I’m not sure how to judge what is considered normal versus problematic.

Because the issue improves after restart, I’m wondering whether this is typical resource buildup, session handling, or something specific I should be tuning.

How do experienced users usually approach diagnosing gradual slowdowns like this? Are there particular indicators in the built-in tools that suggest a real problem rather than expected behavior?

While reading more about how browsers manage memory over time, I found this general explanation helpful for understanding the bigger picture:
