Firefox 技術支援討論區

I am facing a critical problem with my website when accessed through Firefox. The browser is not properly loading my website; instead, it cuts off the page and frequently hangs, causing a frustrating user experience. This issue needs urgent resolution as it affects the accessibility and functionality of my website for Firefox users. I am seeking assistance to diagnose and solve this problem promptly.website

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.

When watching a video on youtube using firefox the network speed displayed by youtube is significantly slow that when on a chromium browser in this case edge. I have tried prievous suggestions such as disabling Zero Round Trip Time Resumption (0rtt) and tried in troubleshooting mode, neither have an effect. I have attached screenshots from the same video from each browser.

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.

In the last 2 weeks (that I know of), Mercari will not appear when I go to it. I just get a blank page. I've restarted the computer, I've turned off the Ublock and Ghostery but nothing. Everything else works fine. I am not very computer adept, by the way. I sell things on Mercari, so I kind of need to access it. I'm not even sure I picked the right topic (website breakages)....sorry if I got it wrong.

After the last update

When you click on a product on eBay you get a disorganized page.

See they upload image.

I an not having this issue with any other browsers.

Edge, Oprea, and Chrome all work fine.

Any Help?

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

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.

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)

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

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!!

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

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

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!

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.

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.
