Initial performance is good, but over time especially when tabs are opened and closed frequently responsiveness to user input (e.g. tab switching, opening/closing tabs, response to hyperlinks) becomes very slow. After force quitting and restarting, performance is good again for some time. I exclusively use private tabs.

Since yesterday, I have not been able to add new bookmarks. I want to add two new ones. (I can update or delete bookmarks.) I have read and tried the solution article (https://support.mozilla.org/en-US/kb/cant-add-change-or-save-bookmarks), but the fix did not work for me. I am using Windows 11 Pro (fully updated) and Firefox 143.0.1 (64-bit). By the way, Brave is my secondary browser. I can add the two new bookmarks in it without problems. Could someone provide a solution other than the one in the article that I have cited? Again, that solution did not work for me. Thank you.

I've been using Firefox for years because more popular browsers like Chrome and Edge have anti-features I dislike. In recent years, however, it feels like Mozilla has been more eager to follow trends set up by it's larger competitors even when those trends seem destructive to the principles that used to be at the core of this project. AI is the final straw for me. I don't understand why I would even use Firefox over Chrome if both are full of AI anyways. Even if AI wasn't a deal-breaker for me, I'm worried Firefox will make similar decisions later. I want out.

Is there any good and maintained alternatives to Firefox? Something like how Firefox was just a handful of years ago? Maybe a fork of an old version?

Firefox repeatedly crashes on my, multiple times a day. I'dc really like to NOT have to change my default browser to Chrome.

What happens is that Firefox freezes, and I get a white bar at the top telling me so. I get a popup box asking if I want to close Firefox or wait for it to respond. Waiting doesn't work, so I always have to close Firefox. When I reopen it, fortunately all m,y open tabs are retained, but it crashes again within minutes or seconds as soon as I click on anything.

There only thing that seems to work is a reboot of my PC. But the respite is short before Firefox crashes again.

I've disabled most plugins, but that hasn't helped. Is there a way to create an event log within Firefox that I can share with someone at Mozilla to help e debug the issue? It's got to be something local rather than Firefox itself; I can't imagine this is happening to most users.

I'm simply trying to email someone using the email link on their site.

The link is a mailto link which requires an email application (which I don't have). All I want is to copy the link to the clipboard.

Firefox lets me right click the link and copy the email address, but this doesn't allow me to provide the required Subject specified by the site's author.

I could have sworn Firefox used to have this feature. Netscape and IE certainly always had it back in the day.

Every time I try to upload a file to the Microsoft Copilot 365 I keep getting the "Error Occurred Please Try Again" But when I switch to Chrome. I can upload the same files with no problem. Does anyone know why I get the "Error" with Firefox?

Login Autofill in Android 14 not happinging despite all possible settings. I found. Google only gets to do it. Any ideas on how to yank it loose, so Firefox gets it? Firefox is set as the default. Autofill app.

With Firefox 144, there is unasked for/unwanted AI introduced. How do I ensure that all AI is completely disabled in my browser? I found a link describing some settings, but want to confirm this will disable ALL AI in the browser. I don't want it, don't trust the privacy/security holes yet to be found and would prefer it was not included in Firefox to begin with. The list I've found is:

• user_pref("browser.ml.chat.enabled", false);
• user_pref("browser.ml.chat.menu", false);
• user_pref("browser.ml.chat.page", false);
• user_pref("browser.ml.chat.shortcuts", false);
• user_pref("browser.ml.chat.sidebar", false);
• user_pref("browser.ml.enable", false);
• user_pref("browser.ml.linkPreview.enabled", false);
• user_pref("browser.ml.linkPreview.optin", false);
• user_pref("browser.ml.modelHubRootUrl", "");

Will this do it? What about:

browser.ml.chat.nimbus

Do I need to clear that field to ensure I don't get some auto opt-in in the future as more and more of this "stuff" is put into the browser?

Why not leave Firefox as a security/privacy conscious browser and put out a separate AI browser (FirefoxML?) for those that are not as concerned. How does Mozilla ensure that no information is leaked through AI from sessions for professionals that must protect physician/patient, attorney/client information or other legally confidential information?

Hi, Since the last update for Mozilla on the laptop (updated on 6/Oct/2025 - version 143.0.4 (64-bit)), all the shortcuts to websites in Firefox homepage I had pinned have disappeared. Also I can't add new shortcuts. I already have shortcuts enabled in Settings>Home>Firefox Home Content>Shortcuts.

Does anyone know how to solve this?

Kind regards.

The scrollbar slider isn't displaying correctly. If I grab the screen, zoom in, and look very carefully, it is possible to see that the slider is a very slightly different darker shade of grey to the rest of the scrollbar, but it's almost impossible to see, so something is clearly not working properly here. The scrollbar should be highly visible as it's the most often-clicked control of the entire browser.

Unlike before, many sites that I visit regularly, I am now having to log in every time I visit, including support.mozilla.org.

Did I unknowingly change something, some setting? or perhaps it's due to an addon?

iOS 26.1 on an iPhone SE; Google Maps 25.47.0. Links to apps don't open in-app. If I click a Google Maps link, it sends me to the App Store. If I click a link to Instagram, it sends me to the App Store. But I already have those apps! How do I make it work like it used to?
