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

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.

i was watching youtube when this happened here is the link https://www.youtube.com/watch?v=o25FuR0eUAs the error "your browser cannot play this video"

When I try to log into the site, the system sends a 2FA code. I enter the code an Firefox goes into a loop waiting for the server. When I use Chrome, I get right in. I do not want to be forced over to Chrome. How can I fix this?

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?

No idea if this is happening to anyone else:

When I use Dropbox for web on Firefox on a new Macbook pro, every so often the screen will completely glitch out and you can't really do anything on Dropbox. By glitch out I mean the screen just becomes really shaky, like non stop shaking back and forth and you can't click anything or navigate at all.

Anyone have any idea why this is happening, video here for reference:

What can I do to get my "upgraded" Firefox to display Facebook correctly. Right now, it is basically a blank page. Edge still displays Facebook correctly. Please try to give instructions that a non-expert can follow.

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.

i dont know why but when in fullscreen sites have weird borders around them it seems to be a firefox issue i dont know how to fix it.my computer runs windows 11 if that helps.

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.

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.

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).

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

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'm experiencing consistent issues with my website that seem to result in breakages across various browsers. Despite my attempts at troubleshooting, I haven't been able to identify the root cause or find a solution. Here are the details:

Website URL: [Your website URL] Browsers affected: Firefox, Chrome, Safari, etc. Breakage symptoms: Describe specific issues such as broken layout, dysfunctional elements, error messages, or any other visible problems. Steps taken to troubleshoot: List the actions you've already tried to resolve the issue (e.g., clearing cache, disabling extensions, checking console errors). I've ensured that the website is up-to-date and compatible with modern web standards, but the issues persist. Could someone kindly provide guidance on further steps to diagnose and resolve these recurrent website breakages? Any assistance or suggestions would be greatly appreciated. Thank you!

Hi, I installed the new update yesterday. This morning, I cannot access anything through my usual Firefox browser. I'm making this report from Google - which is working fine on the same computer. When I try to access any websites, the usual tab opens with a greyed-out "X" (or hourglass?) on the left of the tab - then nothing happens. I've tried restarting - no luck. I suspect yesterday's update was flawed/had a glitch. Please help.
