Firefox Community Forum

Usually I login to my account on a public PC and when I finish my work, I log out and erase all data. From some build it doesn't fully erase the history, meaning it reloads my tabs when another person opens Firefox.

It nags me, that I ain't asked if I want the AI function, you just force it over me without giving me any choice, if I want it..

SO, how to COMPLETELY remove the AI function in Firefox and Linux Ubuntu..

AI scare me and I definitely don't want ANY of it!!!

I can not edit the domain address in the password save section. I can change user name and pw, but not the domain name/address. This is very annoying for sites like twitter that have now changed to x as it's not straight forward and prohibitive to my own saved information and it not allowing me to alter it in the EDIT section. Thank you for any help you can provide.

Hello,

as per description I noticed that firefox version 138 requires an ArrayBuffer as the argument of WebAssembly.compile() and doesn't allow anymore (like in 137) a SharedArrayBuffer, is this intended or it will be fixed in the future? Follows a simple test case. Kind reagards.

--- index.html --- <title>Example</title> <script> let instance = undefined; async function loadWasm() { try { const response = await fetch('./sum.wasm'); const buffer = await response.arrayBuffer(); const sharedBuffer = new SharedArrayBuffer(buffer.byteLength); const tmpView = new Uint8Array(sharedBuffer); tmpView.set(new Uint8Array(buffer)); const module = await WebAssembly.compile(sharedBuffer); instance = await WebAssembly.instantiate(module); } catch (error) { alert(`failed to compile in wasm: ${error.message}`); } } loadWasm(); function testWasm() { if (instance) alert(`sum 1 + 2 = ${instance.exports.add(1, 2)}`); else alert('invalid instance, failed to compile'); } </script> <button onclick="testWasm()">Press to run wasm function (sum)</button> --- ---

--- sum.wat --- (to convert into .wasm using: wat2wasm sum.wat -o sum.wasm) (module (func $add (param $lhs i32) (param $rhs i32) (result i32) local.get $lhs local.get $rhs i32.add) (export "add" (func $add)) ) --- ---

Using 2025-04 Cumulative Update Preview for Windows 10 Version 22H2 for x64-based Systems (KB5055612) Firefox 138.0.1 (64-bit) and says it is up todate. I have looked at the about:config to find the browser.tabs.remote.autostart but it does not exist in the list of processes. I have also unchecked in settings both performance options intermitently to try and correct this problem, but nothing happens: (unchecked) Use recommended performance settings Learn more These settings are tailored to your computer’s hardware and operating system. (Unchecked) Use hardware acceleration when available Nothing pops up to allow choosing a different number as many support articles say. I have AdBlocker running as an add on and turned off the duck duck go privacy essentials and still nothing stops these insane amount of processes clogging up my computer. right now, on this page there is only this tab open and there are 13 processes running. Please send real fix instructions- thank you

We want to use Firefox on a locked down system. Using the -kiosk command line argument gets us most of the way there. But they still have access to the devtools when they hit F12. It appears there are ways to disable devtools after the browser has been started. How can we disable the devtools before the browser is opened and without registry changes?

Yesterday evening I accidentally clicked on a setting that asked me to stop or deny something and I don't remember what it was. Today my bookmarks and history prior to yesterday evening is gone. Is there a way in the system to go back to yesterday evening and undo whatever I clicked and restore the missing history and bookmarks? I work on MacOS and am using the current version of Firefox 137.0.2 (64-bit)

I went from Chrome to Firefox several months ago when I discovered that Firefox would automatically reopen all open tabs from previous session. I always put my pc in "sleep" mode at night. This morning it wouldn't "wake up" so I held the power button down until it shut down (Windows 11). Then I hit the power button and it started fine. I opened Firefox (Version 333.0) and all my tabs were gone. My wife uses Firefox on her Mac laptop and the same thing happened to her. She put her laptop to sleep last night and this morning all her tabs were gone.

After 3 hours of restoring my tabs, i went to settings and the option for Firefox to reopen all tabs from previous session was grayed out and clicking the circle next to it didn't do anything.

I am assuming this was caused by a Firefox update and am hoping someone has a fix for this. I'd hate to go back to Chrome, but I can't live with spending three hours of each day restoring tabs. I'd appreciate and be eternally grateful for any assistance and fix for this issue.

Thanks!
