Firefox Community Forum

Hi,

Please tell me exactly WHAT AI, WHERE that AI is, and EXACTLY what DATA is transmitted, on an option that's enabled BY DEFAULT on Firefox.

"Use AI to suggest tabs and a name for tab groups"

And the same question for ALL other AI features.

There is ZERO transparency on this issue, and I'm mightily disgusted that you feel the need to, by default, force share the EVERY WEBSITE VISITED with a third party AI system.

After a re-start, my Firefox browser on a Dell laptop lost all history and has since also not been collecting websites visited. When opening a new tab, the shortcuts and recently visited websites are also gone and no longer being collected. My CCleaner recently updated itself to a new version but I unchecked the delete history for Firefox (which treacherously is clicked by default - I fell into that trap before). Happy to blame the new CCleaner but that would not explain why history is not being collected now - to me the fault seems to lie with Firefox instead. Another possibility that went through my mind: Is Microsoft sabotaging users of Windows 11 to force them to buy new? PS: Under "Privacy", "History", the setting is "Firefox will remember history", as it always has been and should be. But it has forgotten all previous history and it is no longer collecting any new history either!

I have Privacy & Security set to Strict with Cookies and Site Data deleted when the browser is closed with only 3 sites in the exclusion tab. I also use a VPN to assist with masking and for connections to defined systems and as part of that I will randomly set it to different countries 'because I can'.

I was looking at the website for the current Rugby World Cup (https://www.rugbyworldcup.com) but it was showing the wrong times for the matches. A little digging showed it had remembered my location from some point last week when the VPN was active and set to Iceland.

There is nothing I can find in my browser settings to permit this and I would appreciate pointers to check further since one of the reasons I have set the higher level of restrictions in my browser is to stop this kind of activity from websites.

Please forgive me if this already exists here (I suspect it does). Search tools did not yield what I was looking for.

TOPIC: Extended Support for Firefox 115 ESR

First, let me extend a hearty thank you to everyone on the Mozilla team and in the community that is continuing work on 115 ESR. This is helping a number of people that cannot upgrade for various reasons.

115 ESR is the last hope for many who are stuck on macOS 10.12-10.14 or Windows 7-8.1. While these systems are considered *very* out-of-date (users who are still on them are often chastised) they have a place. macOS for example, completely removed any and all support for 32-bit software as of macOS 10.15 ("Catalina"). I have encountered people with needs for 32-bit to run older apps and so they often keep a system running 10.14 ("Mojave").

Now, can old 32-bit configurations be kept around and isolated offline? Yes. But for some out there who cannot afford to upgrade, or cannot be with out specific 32-bit software, they would be forced offline completely (assuming they follow best security practices, which many do not). I have personally deployed 115 ESR on a number of systems to help people in this situation.

For the time being, ESR 115 is permitting these users to stay online with some degree of security, at least where web browsing is concerned.

QUESTION: Besides active user count, what other factors are keeping 115 ESR in active security-only support mode?

I tried making a PWA ("Add tab to taskbar") for "https://discord.com/channels/@me," but when I launch it, it only navigates to "https://discord.com," which is a splash page that prompts you to either download the Discord desktop app or continue on the web (clicking to continue on web then takes you to ./channels/@me). Examining the desktop shortcut for the PWA confirms that the URL it targets is "https://discord.com"; however, changing this url manually in the shortcut then relaunching it STILL only navigates to the discord.com domain, not the full discord.com/channels/@me url path that I specified.

Can anyone else confirm whether PWAs can only currently target a domain, not a specific url path?

I installed Firefox on my new computer. It imported setting from Chrome. That's not what I wanted at all. Now, I can't get rid of that information that was imported because it synced. How do I get rid of this data permanently? I have Firefox on my old computer but I don't want to connect online for fear it will sync and contaminate my other Firefox installations. How do I clean out my online profile?

whenever i scroll trough a website in firefox, the ewperience is very laggy, feels like its 15fps. i have done basic things like disabling hardware acceleration, smooth smooth scrolling.

What is the cause and remediation of my constant Firefox notification about the geolocation database being updated?

Firefox 16:35

"Geolocation databases updated

The IP geolocation databases were successfully updated in 2 seconds.

I am using the Firefox AI Chatbot in the sidebar and facing an issue with the text input behavior. Currently, pressing Enter immediately sends the message instead of creating a new line. This makes it difficult to format or write longer messages. It would be very helpful to have an option to change this behavior—so that pressing Enter adds a new line, while something like Shift+Enter (or a setting toggle) could be used to send. Many chat apps and AI tools provide this flexibility, and adding it to the Firefox sidebar would make the experience much more user-friendly.

Hi, I rebooted Firefox today because a website was frozen, and when it came back, it was asking for a troubleshoot or just continue, and I don't know exactly what that meant, but when I clicked on refresh, everything was changed, including the theme. And then when I tried to restore the theme back to the original it said, add-ons are disabled by safety, and I don't know what that means, and it's not explaining how to undo it. And now everything looks different and I'm not happy with it, and it's not really letting me add any other themes, and if I add them, they don't seem to fully load, the page still looks all white

Hi! I'm on a relatively new to me (refurb) desktop computer running Win 10 Pro (64 bit)* and Firefox 143.0.3.

In the past week both Firefox and Win 10 have updated. I don't know what happened, but now when I boot up or reboot, my computer opens to MS Edge. Yuck!

Every single time I have to reinstall Firefox! Once I do that, all is well again. I have all my bookmarks back, etc.

It also keeps changing my "default to Firefox" browser setting, turning it OFF, while I'm using Firefox. I repeatedly have to keep going in and clicking to make FF to the default browser again.

Why is it doing this? How do I stop it?

Anyway, I know I can't delete Edge or uninstall it. How do I shove it back into the black hole it has lived in until now?

Thanks very much in advance for any help offered. :)

I closed a PDF file but can not move it to another folder. Windows says it is open in firefox. I closed firefox and it still says it is open in firefox. I even restarted windows and it still says it is open in firefox. How do I get firefox to close and release the file?

Only on firefox, the music on apple music keeps changing volume. I can hear it sound fine for a second but then it changes the volume to around half of what its meant to be. I dont see any settings to change it, its fine on other browsers, im genuinely unsure of what to do.

Hi everyone,

After enabling `privacy.resistFingerprinting = true` in `about:config`, I noticed that Firefox’s built-in PDF viewer (`pdf.js`) is always displayed in **light mode**, even though my system and browser themes are both dark.

I understand that RFP forces `prefers-color-scheme: light` to prevent fingerprinting, but this also affects internal components like the PDF reader. Unfortunately, the PDF viewer doesn’t provide a manual dark mode toggle.

Is there any **official or safe workaround** that allows keeping RFP enabled while still having the PDF viewer use dark colors?

Thanks!

My network is pretty fast -

• Download Speed - 76.30 mbps
• Upload Speed - 113.13 mbps
• Idle Latency - 61 ms
• Download Latency - 59 ms
• Upload Latency - 18 ms

Even though this is a pretty fast network connection, my websites on firefox take a long time to load, for example youtube takes like 2 seconds to load, and sometimes some elements of the website do not even load. This is a very annoying problem which I would like a solution for.
