Diễn đàn hỗ trợ Firefox

I have no desire to interact with Google, Bing, or Perplexity, and as a rule I don't want outside parties (such as Firefox/Mozilla) deciding for me which search engines or other service providers I see advertising for. (And yes, seeing that "G" logo somewhere is advertising for Google.) I'm assuming that these companies are paying to be pre-loaded as search providers in Firefox, and I understand that Firefox needs this financial support if it's going to continue providing a browser.

After upgrading, I've always gone into the settings and removed these search providers - I don't want to see them offered as search options, and to be honest, I don't even want to see their names in the settings screens.

Now with Firefox 152, I find that I'm not able to delete these pre-loaded search providers anymore. I can turn off a switch to disable them, but there's no way to totally delete them from the list anymore. There's even a [in the documentation] which explicitly says that the pre-loaded search providers cannot be removed, only hidden.

'WHY can I not delete them?

Is there a technical reason, i.e. would the browser stop working if they were removed? Are some companies paying extra to not be delete-able, and it just happens that every one that's pre-loaded in Firefox 152 decided to pay the extra money? Or did Mozilla just make an arbitrary decision to reduce the level of control that users have over their own browsers?

Hello,

I am dealing with a quite frustrating issue, and I literally cannot do anything to stop it from ruining my messages.

Whenever I manually type in WhatsApp Web or AI chats (like ChatGPT or Claude), Firefox completely hijacks my text box. As soon as I start a line by typing "1", a period, and a single space ("1. "), the browser forces my text into an auto-formatted numbered list.

This isn't just unhelpful; I see it as a genuinely harmful feature. The formatting it forces on me is weird and broken—it frequently adds massive, irrelevant paragraph gaps between list items, completely messing everything up.

I am completely stuck because standard fixes do not work:

If I press Ctrl + Z to undo the auto-formatting, it also deletes the space I typed.

I am not pasting anything; this happens the millisecond I type the spacebar from scratch.

It feels awful to have my manual typing hijacked like this. Users should be able to type a simple number and a period without the browser transforming it into a broken HTML list.

Is there an about:config setting or any way to completely disable this auto-formatting feature so I can just type normally again?

Thank you.

I want to delete Preview Links. I tried going to Settings>General>Browsing, however, there is no "Browsing" section. I have a Linux Mint. I do NOT want Preview Links. Thank you.

Hello,

I'm encountering a highly frustrating issue with Firefox. Even though the "Open previous windows and tabs" option is checked in my settings, it is completely ignored on startup. Firefox systematically opens to a blank tab or home page.

Here are the key details and what I've already checked:

• The Ctrl + Shift + T shortcut works perfectly: This proves Firefox is saving my session and history; it's only the automatic loading on startup that is being blocked.
• In about:config, the preference browser.startup.page is correctly set to 3.
• My privacy settings are standard: Firefox is set to "Remember history" and the "Clear history when Firefox closes" box is unchecked. I am not in permanent Private Browsing mode.
• The Windows shortcut I use to launch Firefox is clean (no forced URL at the end of the target path).
• I close Firefox cleanly via the menu, and I've verified that no ghost processes are stuck in the Task Manager after closing.

It makes no sense since the parameter is hardcoded but gets bypassed on launch. Is there a specific file (sessionstore or otherwise) that could be corrupted and blocking the automatic load without blocking the manual restore?

Thanks in advance for your help, I'm out of ideas!

Hopefully, this gets you a fast and highly technical answer. Hang in there!

Moderator note: This question has been edited to correct the formatting.

Firefox recently had an update, and now when I am uploading files, I can't double click to upload selected files. I have to first select the file, and then click the open button.

Before the latest Firefox update, I could simply double click on files to upload. This workflow was much faster.

If I go to about:config, and search for: widget.use-xdg-desktop-portal.file-picker, I can change the value from 0 to 2, and then I can upload files by double clicking. However, then Firefox forgets my last upload location, and always opens in the home folder.

If I set it back to 0, it remembers my last upload location, but I can't double click to open files.

My current Firefox version is 152.0.1. Any help would be appreciated. Thanks.

how can i restore control of my device? I keep receiving this: "someone else, like a parent or administrator, controls settings on the network, browser or device that you’re using", but it is my device and I am a 41 year old adult.

I REALLY don't want to see prompts like this ... when FF upgrades to a newer release. I postponed clicking on adding this application since I really didn't know what it as going to do, or how to remove it once done. The little 'i' in the red circle did nothing. So - I finally clicked on it to make it go away. Not hat I call a very seamless upgrade.

Dear Firefox Community,

I don't want to follow football. I don't want to see world time. I don't want to download Firefox for mobile. I don't want to change my home screen background. I don't want any new widgets automatically enabled.

Kindly tell me if there are any setting/options/flags (including in about:config ) to avoid any new popups about all those very useful features for as long as possible.
