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.

Hi Guys,

I am using an older OSx version which I am happily using Firefox 78.15 with no issues. Last week I easily attended meetings via Google Meets with no problems to date, until today.

All of a sudden it states that my browser doesnt support it. I have tried all workaround, uninstalled add-ons etc.

Was there a sudden change? This will affact my day to day work if meets no longer works.

Any information please help

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

I'm not sure what happened because it never broke sites like this before. Sometimes it makes a site impossible to read. I haven't done anything to the browser and this just started happening.

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.

4 PM, November 7, 2023 EST. The "About" page of all YouTube channels suddenly disappeared, whatever the the login status. A compressed version will show up from a channel's home page when clicking on the site description from its Home page. Make things weirder, ~6:15 PM it WAS visible from the Tor browser but started acting the same. I have no ad blockers, or ANY extension installed on any apps, including Firefox/TOR browsers. Updates to both browsers were made prior to this behavior. It may be Google/YouTube's fault but it's becoming frustrating because I prefer Mozilla's browsers over Edge or Chrome.

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.

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

Hello, I did something stupid. I was trying to set up the dark/light theme via cli, and I asked openai about it.

It suggested this command:

echo 'user_pref("lightweightThemes.selectedThemeID", "firefox-compact-light@mozilla.org");' | jq -s '.[0]' > ~/.mozilla/firefox/*.default-release/prefs.js

Which resulted in the following error:

jq: parse error: Invalid numeric literal at line 1, column 11

When I opened mozilla, my profile was reset, and websites won't load (except this one!). They just hang there loading forever. My internet is fine, chromium works perfectly.

So how do I fix this and is there a way I can recover my profile? (Yes I know I should've made backups)

Firefox not responding to general websites on the web (Ex: Amazon.com, etc.). I have several Mozilla-recommended security extensions that may be working against my firefox connecting to these general-in-nature websites.

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).

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!

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.

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

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.
