Firefox Support Forum

I'm still running Firefox under Windows 7. I've now connected a new monitor with a resolution of 2660 x 1080 using an HDMI cable (previously DVI), and since then I've had major problems setting up websites. the websites are only partially built and I have to reload several times. Can you help me?

Im trying to use 192.168.1.131 to acess a netgear wireless point the Firefox is stopping me from going to this legit site I have turned everything off and still no luck I keep getting a non trust certificate Blaine

I am trying to find answers in relation to my Favourites shorcuts not showing the Icon for some well known websites e.g BBC World News, CNN. Once answer found on the Firefox Forum is: Make sure that you allow pages to choose their own fonts.

Tools > Options > Content : Fonts & Colors > Advanced: [X] "Allow pages to choose their own fonts, instead of my selections above"

This is just typical of many answers I find on the Firefox forums whereby the suggested solutions seem to bear no resemblance to my Firefox system. Am I using something different? Everything points to me having the latest up to date version of Firefox. For example if I click on the four horizontal line hamburger on top right of the screen I do not see anything that begins with "Tools" in the menu options. I see "Settings" and "More Tools" but none lead to "Options>Content: Fonts & Colors> Advanced: [X]. simarly, If I click on "Tools" in the menu at the top of the Browser nothing leads to "Options". Any suggestions please?

I have attached images of what slowly occurs when I don't clear my cookies, websites start to slowly and slowly load less and less until they eventually completely break and wont load and I have to clear my cookies, resign into everything. and rinse and repeat every few days or a week, I also attached an image of what the purchase screen is supposed to look like. Looking at this via Microsoft edge

When I try to log into my Tesco Groceries through Firefox on my pc I get Oops it looks like something not working. It works fine on my firefox on ipad and I can get through no problem with Chrome , Can you help please. I can get into my Tesco Bank ok. I have been told by Tesco that Firefox version 122 does not work I should change it to 120, but it wont let me do that

I am a startup founder. I'm making a webgl rendering engine. I'm doing a stress test with 4 large paragraphs amounting to tens of millions of triangles on a macbook air. Firefox is on the latest version.

When I run the app in chrome/safari/opera, the performance is normal. ~45fps. But in Firefox, it's very slow. My FPS counter (in a requestAnimationFrame loop) says ~45fps on all browsers. But in Firefox, even though the counter says that, the real frame rate is ~3-5fps.

When I try to profile, the problem magically goes away and we're back to ~45fps. I played around with profiler settings, and the key determinant is whether or not I'm taking screenshots. No screenshots = slow. Screenshots = fast.

In the flame graph, in slow mode (no screenshots), it seems like I get stuck in the canvasRenderer and the Renderer mostly waits for it. But in fast mode (with screenshots), the canvasRenderer keeps up and the Renderer spents most it's time in: iokit_user_client_trap

I'm not sure what to do. This is only a problem on Firefox. There's some sort of gpu/threads/something that switches when I profile with screenshots that makes it way faster. This performance hit basically ruins my app for Firefox only. Any idea what I should do?

Videos (with the exception of those on YouTube) have no sound, and in some cases such as Amazon or Plex, fail to play at all. Amazon directs me to plugins, and to select 'Always Activate' on Widevine Content Decryption, and to update plugins. This was already the case and had no effect. Plex, in some cases, simply gives the error: 's4032 (Manifest)', though this could be a different issue. Other videos on Plex have the same problem of no sound. This problem doesn't occur on other browsers like Chrome or Edge.

On a couple of sites (e.g. Petapixel) when I click "Load Comments", nothing happens. I suspect this may be because Firefox security is preventing comments from loading because of site tracking or other security issues. Is this the cause?

Goodd day from UK I run firefox esr 115.9.1 and find the the F5 refresh key does NOT refresh the images. The same applies when using the "reload" icon in the menu.

Reading other posts, nothing seems to apply here.

There are NO add-ons at all and everything is cleared on close. The text DOES seem to change.

As a web developer checking updates this is extremely annoying as only hope is keep closing the browser (to clear everything) and restart - the loads new images etc.

I use several versions of Firefox (2, 20, 56) to ensure compatability with olf browsers and it seems to be only those over 100 with this issue.

Does anyone know if this is a "feature" or a"bug" and is there any simple (!) way around the issue?

Thanks

p.s. ALWAYS happens, not intermittently

As of today every time I open a FF window it has a sidebar for history. I do not store history and need to stop this. I do not want to close it i want to disable this annoying new function or I need to delete FF and choose a different browser.

Windows 10 Pro v 22H2 Firefox 121.0.1 (64-bit)

I have tried preventing Firefox from autostarting with Windows start up by examining these potential program starting locations:

Firefox-Settings-General: "Open Firefox automatically when your computer starts up": Option not available about:config - toolkit.winRegisterApplicationRestart - set to "false" No listing for Mozilla or Firefox in Windows 10 "Startup Apps" settings page No listing for Mozilla or Firefox in Windows 10 msconfig.exe/System Configuration-Startup No listing for Firefox in Windows 10 Task Scheduler No Firefox program in Windows 10 - %appdata%\Microsoft\Windows\Start Menu\Programs\Startup folder All Firefox extensions (2) are disabled

Where else should I be looking? Thank you

Ok. The update downloaded 2 1/2 days ago. I've used Firefox since that download. It didn't install until now. 2 1/2 days later. Why the long delay? And why don't you have something show up in the banner or toolbar that designates that an upload to Firefox is happening? Now, we all have to guess why Firefox is behaving slow and erratic, close and re-open, and check for version.

Hi -- I hope someone can help with this recent problem that has cropped up. Videos that are supposed to be autostart, such as news stories embedded on pages of news sites or video feeding into a side panel on a college sports site I frequent are just continually in buffer mode with the little spin icon in the middle of the screen. This also happens with some, but not all, YouTube videos.

This is a recent development and I didn't do anything to change my setup. I did try updating to make sure I have the most recent version of Firefox, so that's been accounted for. If I close out Firefox and come back to it after a couple of minutes, the problem is cleared, but it only lasts a little while before it begins once again.

Any suggestions? Thanks!
