Firefox Community Forum

So anytime about a month ago, everytime I boot up my PC then first thing I do is double click on Firefox to open it and that worked fine until a month ago, now when I do it youll see the circle spin for 1 second and spot but Firefox doent open, no matter how many times I click on it, the only way Ive gotten it to work is that I have to restart my pc and try again until it eventually DOES open when I click on it, I usually have to restart 3-5 times before itll open.

Im wondering why that is and how to fix it? I havent done anything new to my PC since then, no new Firefox addons, also if there was a problem with Firefox itself then restarting should never make it open yet it eventually works after a few restarts. soooo i cant be Firefox right? Ive also tried refreshing firefox as well as going to add and remove programs and uninstalled it then reinstalled it the issue still remains, any way to fix this?

As the first screen capture shows (sorry it's in spanish), my PDF documents tend to not print on the full page, but rather only on the top left corner of it, i've already fiddled with the scaling and fit to page, i have cleared the printer settings from mozilla, still the same, ive gone into the about:config menu and changed paper_height, paper_width, shrink_to_fit, and scaling nothing works. The document prints fine on Edge (screenshot 2), no problems with fit, and what's even crazier is that some PDF files work just fine (Screenshot 3). Honestly i have no clue what else to do.

This problem started yesterday. The sound in YouTube with Firefox is extremely low. As far as I can tell, the problem doesn't exist elsewhere. Other browers are OK with YouTube and other websites that have sound are OK with Firefox.

I reinstalled Firefox and rebooted the computer - still has the problem.

I'm using Windows 11 24H2 (home) on my desktop.

W 11 May, 2025 update really made my computer unable to go online in any way and I had to restore. But FFox updates to have made it impossible to communicate. My phone has trouble s too. So, how do we make stick telephone permissions for, say: G Voice page https://voice.google.com/u/0/calls now? Thank you

Today was the second time in two weeks I have lost every open tab in Firefox. Previous to this, this problem has not occurred in at least 5 years. What is going on? To utilize data from multiple sites takes a long time to relocate sites and this is becoming unacceptable. Firefox updates are better than this. Thank you for your help.

My webmail is not loading. https://webmail.everyone.net/#/login It keeps spinning and never loads (so I can see the boxes to put in my u/p).

• I've deleted the cookies and cache but that doesn't solve the problem.
• I always keep current with FF updates.
• The problem is only on my computer. No problem on my husband's computer.
• No problem in Edge or Chrome.

What next?

I am having a lot of difficulty opening websites ( NYtimes, Washington Post) they takes minutes to open. Sometimes minutes more to open article. ATT says line service is fine. NYT says it service is fine and it works on EDGE Any thoughts?

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)) ) --- ---

I recently updated my Mac OS to 15.4, and for whatever reason, ever since I did, Firefox stopped working. I can open it, but if I try to go to any web site it just has a dot bouncing back and forth like it looks like it's trying to go to the site, but then it times out. I have deleted and re-installed Firefox several times - the last one being version 137.0.2 for Mac, but it still won't open any site. I don't know what to do to get it working and Mac tech support had no ideas other than to contact Mozilla tech support, so here I am. Can you help me? This has never happened before and it makes no sense that it would not work. You can see by the enclosed screen shot that it opens, but fails to open any photos or go beyond that. The 'checking for updates' alert just keeps spinning and spinning. Rick Garside

Even in the notification setting found under privacy and security there are no sites listed, however, I am continuing to get banner notifications even after uninstalling the browser.

When trying to do a search for a video in YouTube Studio, the search seems to freeze. Doing a similar search in Microsoft Edge works OK. This problem started happening several months ago. I've tried clearing the cache for YouTube pages.

Hello I can use mouse because of my condition. I use a stylus tablet wacom cintiq companion. I cant move the tabs around and some other functionality doesnt work such as pressing certain buttons, fox example download button for the snipping tool in firefox.

with mouse it works but not stylus. it started working when i turn off windows ink but I lose the scrolling feature which is something I really need. I tried turning on and off some about:config settings but no luck there. I reset firefox but that didnt work. I tried the edge browser and I get no problems with edge. Other firefox forks have the same issue. I tried windows settings but no luck there.

Need help! Thanks

I have a laptop that died last week. I just got onto a new device, and would like to restore my Firefox settings from that previous device. So, I downloaded firefox, signed in to sync my bookmarks and extensions... and the old device does not appear in my synced devices list. Is there anything I can do to recover my account data? I know it was synced as recently as a few days ago. The device is completely bricked and I will not be able to log in on it anymore. Is there anything to be done?
