Firefox Support Forum

Firefox tells me to close program because Firefox is already running. When I close Firefox then re-open Firefox: same message. When I check Firefox in Task Manager, there are anywhere from 6 instances of FF running and sometimes up to 24. Something needs fixed.

What would cause websites not responding. I have no malware and the cache is clean. Could it be in the properties, or whatever.

Thank you. It's very frustrating.

Hi, Mozilla team I hope that you have a great day, straight to the point, my UI sometimes crashes or some components glitch or don't even work as it has to This is a video below slowed(I couldn't upload the video).

Videos can't be played at higher playback speed Bug

On firefox, I cant play videos at higher playback speed or it'll only play audio or video will endlessly buffer. Using user-agent spoofer and changing to chrome makes it a little less worse but still the problem sustains. On Brave, the video doesnt have any effect of higher playback speed rather it'll make the video buffer and have very strong red contrast.

I get phone notifications that a streamer is live but when I go to their page on Twitch on my laptop, I see them as offline (screen shot).

I've tried clearing cache and cookies and do not currently have any pluggins that affect Twitch.

Hi,

This is for https://outlook.live.com where I cannot access my full list of folders. I am using Firefox on Linux (in Fedora 34) and my scrolling feature hasn't been working for a few days now. When I search for an email in one of the inaccessible folders, the folder does appear.

As an idea... I added https://outlook.live.com to the pop-up exemptions, no luck.

Any suggestions on how to fix this?

Many thanks!

I am trying to access "Boston Scally" website. When I enter their website to window shop, there isn't a problem, but when I go to order a particular item, the web page goes nuts. I am having this issue with a number of different websites when I try to order or pay for the product.

For the last two days, cnn.com won't load and gives a message that the browser is blocked. Can you explain how I can remedy that? It's a rather popular site, so I assume Firefox will want it to work. All my other sites are working fine, so I'm assuming it some adjustment that cnn made on their end.

Upto Firefox v115 this website working fine. after update this website table display right side end. not in position. checked in other browser. working fine in chrome. what to do?. need solution. thank you.

When I went to watch Tubi TV today I got this error message when I tried to load the video:

"Oops, your web browser is no longer supported. Please upgrade to a modern, fully supported browser."

But only for a few seconds, then it shows

"Sorry, there was a problem loading the video player. Please try to reload the page. If you are using an ad-blocker, please disable it or whitelist tubitv.com If the problem persists, please contact us at tubitv.com/support"

I booted my firefox in safe mode, still get this exact sequence of events. My firefox is up-to-date. Is there a workaround for Tubi blocking content from firefox browsers? Is that what this is? Thank you

When viewing any tiktok account profile page, for example this one , the videos do not show up, and says "Something went wrong, Sorry about that! Please try again later."

Here's what i did:

1. Created new Firefox profile with default settings and no extensions
2. Visited a TikTok profile, and saw it opens as expected
3. Changed privacy.resistFingerprinting to true
4. Refreshed the TikTok profile page, and the error message shows up

I opened the console and compared and there were new warnings:

• Blocked https://www.tiktok.com/@tiktok from extracting canvas data because no user input was detected.
• Get user detail failed for getting wrong response

And 3 errors, when there were 0 before, all three read

• Uncaught TypeError: _0x5e9eb8[_0x2bd187] is null

I use photopea.com for photo editing and stuff, but I accidentally clicked on the option to have that site not show a pop-up asking if I'm sure I want to leave the site and asking if I'm sure I want to close a project. Now I can't close projects at all.

Can someone tell me how I can re-enable it for the website?

Hi everybody, since yesterday I cannot use DeepL Translate on Firefox: most of the functions are blocked. I cannot sign into the website or download the app, and most of all the translation function is not available. I have checked uBlock but it doesn't seem to be related to the problem. No problem with any other websites, it's just DeepL. I have not changed any of my privacy or cookie settings, so I don't understand why all of sudden it's no longer working. I can use it in Chrome but I would prefer to restore its functions in Firefox, which is my main browser. Thanks in advance for any suggestions. Have a good day.

Despiote having no problems for years this morning my access to making payments online with the Bank of Scotland was blocked. They have indicated that the problem is Firefiox not aligning with their security. can you fix this as i would prefer t remain with firefox.

between this netflix error, this amazon alert, and youtube auto switching to 360p it's become increasingly difficult to access media. i've called netflix about this and they had no idea what the code was and have not gotten back to me with a resolution.

does anyone know what's causing these issues? is it just companies being hostile to firefox specifically or is something wrong?

i've cleared my cookies and cache, i've restarted several times, i've logged in and out of everything. i'm on version 120.0.1

Hello,

On the webpage https://www.drivethrurpg.com/pub_tools.php Firefox breaks. Image here for reference: https://imgur.com/a/382kw9L. The area in red in the first image is an error.

From the console I saw that the website is shifted to Quirks Mode.

From a discussion with their support they said that this is a Firefox issue, as the website does indeed work fine in Chrome and Edge.

Not sure why this is triggering Quirks Mode.

In the same imgur album (above) you can see that the page has a proper doctype HTML header.

Any ideas?

This is on macOS Sonoma 14.1.2.

If I copy/type anything into the address bar, and press enter, it disappears and the browser remains blank. As does: selecting any website from the address bar dropdown, opening any bookmark, or attempting to open any file. There is no error, so I'm at a loss how to debug this.

Firefox was working on Ventura. Repeatable with Firefox versions 120-115, have not gone back further. Neither troubleshoot mode nor deleting/rebooting/reinstalling changes anything.
