Firefox Support Forum

black page (no video) when trying to watch spacex live or past videos https://www.spacex.com/launches/mission/?missionId=starship-flight-2

When I try to use youtube.com on Firefox I have problems with the page loading correctly. The sidebar menu doesn't populate leaving only a white space where all the options should be. When I click on a video a red progress bar will fill about 75% of the way and then just hang and the video will never load.

I have tried clearing my cache and cookies, deleting all data, refreshing my browser at least 5 times and ran under troubleshooting (safe) mode but the same issue persists.

This does NOT happen under Edge at all, only with Firefox.

Uncontrollable reloading of pages - 2 urls in past week - currently: https://www.4wdsupacentre.com.au/ - refresh occurs at varying intervals from not fully loaded (less than 2 seconds) to 10 seconds

Using Mac OS 10.15.7 ; Firefox 120.0 (64 bit)

I have been a loyal Mozilla user for many years and it will be a lot of work to to transfer to chrome or edge but continuing problem with camera/microphone access and now this rubbish makes it necessary.

Sorry, keir douglas

On https://careers.usmc-mccs.org/psc/hprd/EMPLOYEE/HRMS/c/HRS_HRAM_FL.HRS_CG_SEARCH_FL.GBL?Page=HRS_CAREERS_FL&Action=U when I log in and go to my page, Firefox will not allow me to scroll and see all of the information whereas Chrome and Edge does. I am not sure if there is a setting incorrect in Firefox or it is blocking an area from scrolling. I added a copy of the screenshots below from Edge and Firefox.

After the latest updates the drm protection prevents any streaming of hbo or prime video content to discord. Is this just a mistake from mozilla's side or did 2 streaming sites decide on same week to start ruining their service for paying customers?

I can log into preply.com with Chrome and Edge, but always have problems with Firefox. I was able to log in once, but after that, I can't log back in.

Recently I had to reinstall Windows, and saw the opportunity to try getting this to work. Installed Firefox, but *before* I logged into Mozilla Sync (so I'm working with a 100% fresh installation with no history of having Firefox installed) I tried to log into preply.com. It worked. Then, I log myself out and try to log in again, and once more, I can't log back in. I'm attaching a screenshot of what I see when I try. Please note -- I have no bookmarks, no extensions, no addons, no browser history. Everything is tabula rasa.

I found this page:

https://support.mozilla.org/en-US/kb/fix-login-issues-on-websites-require-passwords

and followed it to the letter, meticulously, to no avail. I still can't log into the site with Firefox. Chrome and Edge, yes. Firefox no. I only have Edge because I can't uninstall it. I only have Chrome for situations like this, where Firefox doesn't work. Firefox is my main browser, and I really, really would like to figure out what's happening. I can't understand how this problem persists when the browser is freshly installed; I haven't imported one bit of data yet from my sync account.

Can someone more experienced than me please help?

Updated FF Tuesday evening and noticed first on Wednesday when unable to log in to my Tesco food website. Access not allowed from this server or some such. I tried to use the Tesco feedback form and then got alerts both from Avast (saying it was infected) followed by FF refusal to connect. I tried safe mode and removing and adding FF.exe to Avast without change. I reset FF without change. MS Edge allowed access to all these sites without a murmur.

Today i can get to Tesco main site but still not Feedback.

Also my local Synolgy NAS now has a warning that it is dangerous to access from FF. Nothing has been changed in its set up or security. I can and do override and access everything

Something in the Tuesday update has caused this clash. I did think at one point I also saw 120.0.1 being offered but that may have been my confusion.

Happy user of FF fro many years and do not want to change.

I need to be able to access banks, specifically USB Direct. I can access my credit union but when I try to get my statement, I get a message that I have been logged out due to inactivity.

Firefox will not display this site properly https://politicalsignal.com/ -- The site is fine in Edge or Chrome

This is the link that Fox was reporting difficulties playing on a Mac running Firefox. I just ran it on my ancient imac using an older LTS version of firefox and am not having any problems (nor with chrome)-

YouTube won't start playing in Firefox. No add-ons enabled. The page is fully loaded, but clicking on Play makes nothing.

The fix is to disable "User recommended performance settings" and then disable "User hardware acceleration when available".

The problem is that hardware acceleration is enabled by default. In Edge or Chrome hardware acceleration is also enabled but it won't break YouTube.

Ever since about a week ago, my Firefox just started... bugging. Twitch doesn't work, now Netflix doesn't work, basically anything that plays videos (except for YouTube) doesn't seem to be working.

On Twitch, if a person is live and streaming, upon clicking their stream to view it, it's suddenly offline, even if the chat is going and the "this person is live" notification is there. Netflix gives me a f7351 error. Websites with online media (like free movies on putlocker) have multiple streaming services attached and neither of them works.

I've cleared all cookies, cache, data and history.

This is only concerning Firefox, other web browsers work perfectly.

Extensions on my Firefox are as follows: BetterTTV, Dark Mode, DocsAfterDark, Facebook Container, FrankerFaceZ, I don't care about cookies, Instagram Dark Theme, New XKit, TinEye, Tumblr Saviour. No adblocks, no nothing.

My operating system is Windows 10, 64bit, Firefox is updated to 119.0.1.

Any help would be appreciated as this has been the bane of my existence for a while.

As run into before, i have constant frustration that was motivating me to switch browsers from FireFox where when i open a webpage in FF i am not seeing full content. I use an extension to then open that page in Edge, and i then do see full content.

The most recent example of this is https://www.godaddy.com/help/contact-us where in FireFox the "chat" link did not appear, but in Edge it did. Similar experiences occur when attempting to log into my account at whitepages.com where in logging in FireFox errors out or returns me repeatedly to the login page, yet Edge completes the process without issue. The Whitepages issue has been ongoing for over 6 months.

Thoughts?

Thank you!

Using text boxes such as comment sections in certain sites will "duplicate" the boxes directly over it Scrolling up and down will lock the boxes on screen and leave multiple traces of the text boxes Refreshing the page will remove the boxes temporarily but will happen again Happens inconsistently on multiple websites Site shown under is dcinside.com

Hey, The website has several blank pages (page cannot be accessed). when i open this site https://boxesgen.com/pillow-boxes/ The page appears to have been contacted, but it is blank in the upper left corner. Is there a reason Mozila is unable to access the website properly?

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

Hi y'all! I've been trying to get netflix to play recently, and I keep getting the error code F7351. I tried looking it up, and didn't get anything, and also tried to dis- and re- enable DRM content, and that didn't work. Does anyone know what to do? Thanks for any help!!

Hi

When I visit the webpages of the Swiss Federal Post Service

    https://www.post.ch/de/kundencenter/onlinedienste

then the scroll bar will not be displayed even though the page is longer than what can be displayed on my screen. As soon as I return to another URL the scroll bar is visible again when needed.

Does anybody know what I can have a scroll bar also for this webpage?

Cheers, Pepe
