Firefox Support Forum

It started this morning (6/23/24) the page for a YouTube video will load but the video doesn't play. I have cleared the cookies and cache, shut the browser down, restarted the computer, turned off all the extensions, and have turned off hardware acceleration. Nothing has changed, I can watch other videos on Firefox and Youtube work as normal on other browsers. Last night (6/22/26) before shutting down may computer for the night I had an update for Firefox and shut the browser so it could update. The image is of what the video section is displaying.

Lately YouTube playing videos have been playing super fast or skipping straight to the end. I mean, they are horribly fast.

Things to know:

• I am posting here because I can't determine whether browsers may have settings unique to them that I need to change. This also happens in Chrome, but not Edge.
• I was recently forced to upgrade to Windows 11 - I can't say this issue happened exactly at that time, but fairly recently after the upgrade. I am running Windows 11 Pro.
• This does NOT happen when playing in a private browser window, either Firefox or Chrome.
• Having the Mozilla VPN on or off has no effect.
• I am sure the playback speed is set to normal. I have tried changing the playback speed to anything but normal and then back to normal and the current video runs correctly UNTIL I play the next video.
• This does not happen with Vimeo.
• It does not happen in FF for Android.

Any questions, thoughts, or advice would be appreciated.

I've removed firefox and reinstalled but for some reason my IOS continuity microphone and my Loopback (Rogue amoeba) virtual devices no longer show in firefox but they show up in firefox beta. Is there a setting that masks these devices off from the production branch?

After uninstall and reinstall my Firefox i can't restore my bookmark. I used (CTRL+shift+b) and restore my file "JSONLZ4". But i have an error as "Unable to process the backup file". I read your forum and test many things but nothing. I also used the https://www.jeffersonscher.com/ffu/bookbackreader.html,but it does not work? It prompts:failed JSON parsing: SyntaxError: Unexpected end of JSON input. I really need my bookmarks! How can I restore them?

Hi,

my firefox does not load any webpage no matter what Firefox profile I am using (created a new one for tests). I have a Win10 pc with Avast and Comodo installed, the system with the mentioned software and multiple different Firefox profiles was running since several years without problems.

A month ago I had the same issue with Firefox 126, which I guess was caused by a windows update, where I had trouble getting it installed. But after this (I had to increase the system reserved partition) Firefox was running without any problmes like before ...

Now no pages kan be load and always the crash monitor pops up.

Thank you so much. Best John

There is a folder on my Google drive called "Personality-provider". It has about 30 .json files. When is search "Personality-provider" on internet the results indicate this folder and files are associated with Firefox. A. Why are these stored on my google drive? B. Can I delete them from my google drive? C. What are these files? D. Are they necessary for me to have backed up? See images. Many thanks. Will

I need working versions of Firefox not messes like I have been getting recently. 127.1 lost most of my passwords and won't link to websites I use every day. This version is a mess. I have had to go through and reset multiple passwords, and can't login to websites I use every day. Check your updates before you release them. I know have firefox set to not upgrade automatically.

When pasting text into Outlook Online the text removes the preceding space. A minor inconvenience but it does mean I have to double space before pasting.

Also after pasting text I get a paste box that locks out any controls unless I click out of it or press ESC. (image below)

Text being copied from inside Outlook doesn't pop up the box.

This problem is only happening with Firefox as using a different browser (i.e. chrome at office) does not do either of the problems. Anyway to fix either option?

I have a form with a date field. it should open the calendar downwards, and does so in a window with 5 tabs open. however in a window with 60 tabs it opens upwards - thus loosing it's head and the ability to change month and year. it's near the top of the form.

moving the tab from one window and back, without refresh etc, shows the calendar down wards (window with 5 tabs) or upwards (window with 60 tabs)

this is looking to me like a Firefox bug - I wondered if anyone has come across this interesting behaviour?

I apologise - ths was on my desk top - but i'm away so don't have many details. I can provide screen shots etc when I get back

many thanks

My master password no longer accepted. every time I try to use it {recently} I get a response please put your master password. It keeps asking me over and over with no result. please help. Thanks.

How can I use Firefox for private browsing or anything when you cannot even keep me as your Default Browser? Edge changes it everytime!! They override you so they have taken over my computer so I can't have firefox as default browser or anything? Thank you, Margaret P Miller peggiemiller1209@gmail.com

Bonjour,

Depuis plusieurs semaines, il m'est impossible de télécharger des PDF depuis firefox. J'ai essayé de faire une réparation, mais désormais j'ai également perdu mes extensions et lorsque je veux les réinstaller, on m'affiche : "Échec du téléchargement. Veuillez vérifier votre connexion." (par exemple pour ublockorigin)

Merci d'avance pour vos réponses, Cordialement Selma

For over a year, I've used my Firefox browser to read the Kindle books. In the top right corner there should be six icons representing 1. Table of contents 2. Search 3. Reader settings (size of font and one or two columns) 4. Annotations 5. Add bookmark 6. Reader menu - this should have five dropdown items including "go to page" which is missing. It now only displays the first and the last, and I want to use "go to page" which is missing.

Another failure of going to the right page - when I log into Firefox on my desktop after browsing Kindle on my Kindle reader, Firefox is meant to go automatically to where I have been reading on the table. Instead it goes to the beginning of the book. That looks like the same problem - failure to go to the right page.

It works fine on Opera but I have to look up my passwords and type in the URL, whereas my Firefox browser shows Kindle along the top, and my password manager works for Firefox. So Opera is very inconvenient.

I guessed that my version of Firefox has become corrupted, but couldn't find how to re-install it.

Why is Firefox refusing to display Instagram videos?

Windows 7 Home Firefox 115.12.0esr (64-bit) Some Instagram videos play, most don't. E.g. https://www.instagram.com/reel/C8FM6cbOG7v/?mc_cid=e24e48195f

For a fraction of a second, the video shows what appears to be the initial display frame, then goes black. Audio plays. Displays OK on Chrome and Edge.

I've explored the following: Autoplay is allowed Turn off tracking protection Clear cache Clear cookies Digital Rights Management (DRM) is allowed Running in trouble shoot mode, i.e. no extensions Popups not blocked I do not have file user.js I tried hiding prefs.js. Hardware acceleration either on or off: no display

Is there a setting that tells Firefox to report why it makes its choices?

When the youtube video is opened, it shows the loading circle without any possibility to start a video. After first refresh of the page it shows the thumbnail of the video, but play button still doesn't work. And then after second refresh it sometimes begin to work properly. The problem exists only on Youtube and its videos. Thank you.

A couple of days ago, I started getting error popups from malwarebytes on Firefox outbound to data.our.news on every page I access. Please see the attached screenshot. Why is Firefox doing this?

I am experiencing a significant issue with my website, which fails to load when accessed via Google Chrome. The website works perfectly on other browsers like chrome, Safari, and Edge.However, when attempting to Click here in mozila, the page remains blank and does not load at all.

Hello Mozilla community,

I'm encountering a perplexing issue with Mozilla Firefox that I hope someone here can shed some light on. Whenever I set Mozilla Firefox as my default browser, I experience difficulties accessing my website. The site continuously buffers but never fully loads, leaving me unable to view its content.

However, when I switch to a different browser as my default, such as Google Chrome or Microsoft Edge, the website loads without any issues moreover my website is related to Picoworker which runs smoothly on other browsers (Screenshot is also attached). This leads me to believe that the problem might be specific to Mozilla Firefox.

I've tried troubleshooting by clearing the browser cache, disabling extensions, and even reinstalling Firefox, but the problem persists. I've also checked for any errors in the browser console, but nothing seems out of the ordinary.

Could there be any compatibility issues between my website and Mozilla Firefox that are causing this problem? Or is there something else I should investigate to resolve this issue?

Any insights or suggestions would be greatly appreciated. Thank you in advance for your assistance!
