I have had Firefox using autofill for credit card payments for years--just replace my iMac with a new Mac Mini, and the credit card info still pops up when I am making a payment, but it will not autofill.

Firefox is already a product that works and is probably the best alternative to any of the other major browsers out there. It's a product that I've been happy to use for many, many years. So why is it being ruined by this needless push to add in "AI"? I don't want it. I don't want any part of it to touch my experience using this browser. I want either an easy way to completely turn it off so it can't suck up my data and expose my private information, or not have it be included at all. I will actively be looking for alternative browsers if these plans continue.

I have been unable to find an email address, so I am turning to this forum to express my disgust at the incoming CEO's comments, namely "Firefox will remain our anchor. It will evolve into a modern AI browser and support a portfolio of new and trusted software additions."

Firefox's appeal as an alternative to Edge, Chrome, etc. is its respect for user privacy and control. Adopting AI tools into the browser itself is a betrayal of that respect, and will eliminate Firefox's advantages over rival browsers. If users want an AI browser, they already have that option. They want, instead, a browser that allows then to control their own experience and data. I beg the Mozilla foundation to actually do some research into your own market so you will learn that people hate LLM slop in their internet browsing.

Adopting AI tools will damage Mozilla's reputation as an organization worthy of respect. What's more, it will contribute to the further erosion of trust in information on the internet that AI has caused, because *LLMs lie and steal*. This is more than just a market mistake, this is an ethical mistake.

There is still time to change course. Do not follow Chrome and Edge into AI delusion.

I've used Firefox for a long time because it's been one of the few browsers that doesn't force features that harm its users onto the userbase. It's been leagues beyond the majority for that long time! The introduction of AI features over time has been a bell ringing for the loss of that thoughtful approach to aiding the users. AI in browsers has been used by malicious third parties to steal the data of anyone who visits specific sites, it's prone to misinformation when used to summarize anything, and simply doesn't add any value to the browsing experience. It gets in the way and slows it down, even! If more AI features are added, I will be finding a different browser to use.

MB is telling me to put MB on Firefox! BUT, I already have MB on Firefox. Can you help me.

Thank you,

Which data are stored in "User Data" and how to clear this kind of stored data? When deleting data in the privacy settings in Firefox, the "User Data" storage is still unchanged. Also "Cache" is not cleared completely.

The "User Data" raises up to 1GB. It is only possible to clear it by completely wiping all data via "Clear Storage" but then everything is wiped, also all Firefox settings etc. "Clear Cache" obviously only wipes the Cache.

I read online that Firefox is planning on implementing AI features. Given the track record of AI in other browsers leaking private information, bogging down connectivity, and generally being a nuisance towards users, I was wondering if there will be opt out features in future updates? Or know of forum threads that will update with tutorials on how to turn off AI features?

If not, does anyone on this forum have recommendations for no-ai browsers?

Once again, when I updated Firefox, it changed a LOT of my settings, including displaying the toolbar and open tabs bar.

When this happened last - months ago - it seems Mozilla realized this had happened to a lot of users, and managed to restore us to all the information that had been "lost".

I hope you can do that again, and can find a way to not put at least ME, and I'd bet a lot of other users, through the OMG!!! What do I do NOW?! panic.

Happy Holidays.

Using your browser as my default and going to https://bracingviews.substack.com/p/yes-its-about-the-oil, https://jonathancook.substack.com/p/western-elites-fear-a-globalised and https://georgehazim.substack.com/p/murdochs-australian-manufacturing, regular sites where I comment often, since Thursday there's no visible button to post my comment. Never encountered that before.

Using another browser, I can comment in Jonathan Cook and George Hazim's Blog but not in Bracing Views

Mozillers,

I depend heavily in my environmental and other work on Firefox and am grateful for its ability to restore previous tabs when my laptop, not infrequently, stops working abruptly.

Now the much-used bookmarks have disappeared. A search site states promisingly:

"To restore Firefox bookmarks, use the built-in backup feature by going to Menu > Bookmarks > Manage Bookmarks > Import & Backup > Restore, then select a dated backup or a manual file (like a JSON backup) to bring back lost bookmarks..."

But my Firefox's Bookmarks drop-down menu has no Manage Bookmarks option. PLEASE, what must I do?

Elsewhere I managed to find this file which apparently contains recent bookmarks:

"C:\Users\User\AppData\Roaming\Mozilla\Firefox\Profiles\unk14jlv.default-release-1647366062305\bookmarkbackups\bookmarks-2025-12-26_95_4IdGtYxezJpwuH1UIiT1bRwe1K6bcGO8rv0mqa9rUWU=.jsonlz4"

But attempting to open it with Applications\firefox.exe (default) accomplishes nothing.

FOOL-proof instructions would be wonderful. Thank you.

The only reason I even use Firefox is to avoid AI slop. Way to take a hammer to your own nuts, Firefox. If the new CEO intends to continue implementing AI "improvements" to the browser, I'm done.

Please help, can anyone answer me. I am on Windows 11. Asus laptop PC. On Google Chrome, any streaming website I used with autoplay enabled would KEEP full screen mode ON after changing episodes. It would automatically go to a new page with the following episode and remain full screen. Why doesn't Firefox have this feature?? I'm seriously considering going back to Google Chrome for this one small feature. Every time I had any streaming service playing with autoplay enabled, I didn't have to manually select the full screen option every time. I am having to stand up and manually click full screen function. Every. Single. Time. This needs to change PLEASE.
