Firefox 技術支援討論區

I have been fighting with Xfinity.com for too long now over a "rendering error occurred: invalid time value" message when I log in to their billing function for my account. I am using a Windows 7 PC with whatever Firefox version is the most current.

Among the responses from their "experts," I see something that has to do with "browser add-ons may be causing your problem."

I have looked at my Firefox settings > manage your extensions as well as settings > manage your plug-ins. Under Extensions enabled I have 2: Norton Safe Search and Norton Safe Web. Under Plug-Ins enabled I have OpenH264 Video Codec and Widevine Content Decryption Module. That's all. Could any of these be causing the problem?

Does this "rendering" error have anything to do with Javascript? (I thought Firefox did not support Java so never paid any attention). If it does relate to Javascript, how do I fix my Firefox browser settings to enable it for the Xfinity.com website to see if that fixes anything?

This is so incredibly discouraging.

Hi, Thank you for your help, this my question: I'm using the dark theme. I would like to change the Menu bar color and only the menu bar color. I don't want to change for another theme or any other color etc. Just change the Menu bar color. This is the same question than here under, but this question was not answered:

Youtube video starts but after 0.5...1s stops, returns to intro splash screen of the video with 'Play' button on it. The play button should be pressed to start the video. The video may be selected on the main page of Youtube or started by entering link to the video - it stops in any case. The same problem when Autoplay is selected: the 2nd video starts then stops after 0.5...1s.

No such problem in MS Edge browser on this PC.

I want to allow websites access to my exact location. Where in about:config preferences do I set this up? I have read many confusing threads about this all over the web. And I may have messed up a few of those preferences. So please tell me about related preferences and what their settings should be too.

I also want to block all other location info such as from my IP, Google, wifi, cell towers, etc.. So that the websites only get the exact latitude and longitude. It is easy for me to get my exact latitude and longitude by searching for my address on Google Maps. The latitude and longitude is in the resulting URL.

I am on a desktop PC using Windows 10 Pro.

This is just a complaint . . . Settings>Cookies and Site Data>Manage Data does not show the server that set a cookie, it only shows the domain -- e.g. domain.com, not https://www.domain.com or even www.domain.com However, Settings>Cookies and Site Data>Manage Exceptions requires the complete server name. If I don't include "https://" or "http://" it adds them. This makes it difficult or impossible to actually manage exceptions; I can't specify which cookie(s) I want to allow, block, or save if I can't see the data that's stored.

Why can't I choose a domain in Manage Data and get a Manage Exceptions pop-up?

Hi! In my setup Firefox tabs keeps crashing for about one week (not sure when it was really starting). In most cases, only one tab crashed and others contiune to work. Only sometimes a second tab crashes at the same time. I also tried the safe mode but the crashes continued to happen.

Here are some crash report ids.

I would love hearing from you soon! =)

I have developed some training with html canvas. The target classroom PCs have no internet connection. I loaded the standard Firefox file on a portable hard drive, but when I go to load it on the classroom PCs it attempts to connect to the internet. Is there an offline version?

I have been trying to remove "Your browser is being managed by your organisation" simply because the browser is on my home PC and not being managed by any organisation. However, I have an issue with registry editor as it does not have Mozilla or Firefox keys in "Policies" "HKEY_LOCAL_MACHINE\SOFTWARE\Policies" or "HKEY_CURRENT_USER". I would be grateful for any advice to overcome this issue as it annoyingly restricts access to web pages.

I don't know if this is a firefox or outlook problem, but I can no longer access outlook live (https://outlook.live.com/mail/0/) from my main screen. Blank page. Oddly enough though, I can access it by going to "private browsing." So I'm guessing there's a setting that's keeping outlook from loading, but I don't remember changing any settings recently, so I'm stumped. This has been happening for only the past 3 days.

12/23/22 After trying for a week to install your mozilla software (thinking this would help to install google play store apps) on my Dell windows pc - it never worked so I requested a refund. I still need assistance in using the firefox browser to install a google play store app specifically the LaView app. Would appreciate your assistance. Henry Mazik

Hi,

I come back to use Firefox and discovered my personal email was associated with an account I created 5 years ago with my professional email that has been destroyed since then.

In the Firefox account settings it says: "Access your account if you can’t log in to your primary email."

But if I try to "Make primary" my secondary email it asks for a confirmation code from the primary email which I don't have access.

If I want to remove my secondary email in order to use it to create another account, it asks for a confirmation code.

If I want to delete the account, it asks for a confirmation code.

It's hard to understand what the use of a secondary email if it can't be used when needed.

What are my option to be able to use my personal email (secondary email of an existing account). Doesn't matter if I have to recreate an account but my personal email is locked to that account.

PS: I have access to the Firefox account but can't access the primary email.

Regards,

Since upgrading to OS Ventura, my iMac can't stream Prime videos on Firefox. My Mac Book has no problem on the same Amazon Prime account. If I use Safari on the iMac, it works fine. Anyone else had this problem?

Hi, Ive looked for a reason for this but i can find nothing. I've freshly installed ubuntu, pop_os and Manjaro. All 3 crash within minutes of starting up firefox. mind you these are fresh installs and there is no cache to clear and no extensions or addons. And what is stranger is the fact that only on Manjaro, firefox is excruciatingly slow. to the point of almost unusable. Is there any thing i can do, or, can anyone help me with this? its been going on for several months. thank you for your help and time Alchamech

Youtube autoplay stopped to work properly.

After previous video next video really starts automatically then, may be after half a second or second, the video stops and returns to intro splash screen of the video. One must press Play to start this next video again. I tried next steps: 1. In Firefox Privacy and security settings / Autoplay: I allowed audio and video autoplay for all sites 2. On the left side of URL string for Youtube site I pressed the button and also allowed audio and video autoplay for the site. The image on this button changed. I reloaded Youtube - no effect, reloaded Firefox and Youtube - all the same.

3. I checked Youtube autoplay in Microsoft Edge browser - it works correctly.

What should be done in Firefox to restore autoplay? I don't remember when this problem appeared.
