Firefox 技術支援討論區

I have uninstalled and reinstalled firefox and restarted my computer but it still will not load. When i first reinstall it it comes up but will not connect to the intenet.

I see my original question is now archived at https://support.mozilla.org/en-US/questions/1380948#question-reply I never closed it because I didn't know if my last process could really fix the issue. It didn't, not always. Over the years, there have been times when the issue would still pop up, but not as often as before (2022 and earlier).

I have a feeling that during an issue, FF is having difficulty setting up shop after starting up. Consequently, it is spending more time before it could become prepared to connect to the Net. I've come up with another "solution," which is deleting (or moving out) xulstore.json in the profile folder after exiting or before starting FF. You can create a batch command or script to execute the process.

So far, FF is connecting immediately after startup.

Nothing happens when I press the play, like, dislike, notifications, favorite, or join server buttons. On top of this, when I try to open the catalogue it's just a grey screen with nothing in it. In the attached GIF I am clicking rapidly. I don't believe this is an issue with roblox itself, as when I open chrome everything works perfectly. The only extensions I am using for the site are RoPro and BTRoblox. I have tried to turn the extensions off and have even uninstalled them, however the problem was still not fixed.

I had used and uninstalled Chrome, and others. All I have is FF and ME. Some times when I attempt to open a web page, FF fails and I have to use ME. But other times ME fails and I need to use FF. I recognize that all browsers other than FF are the same or similar basis. So, how can I stick with JUST FF. And not have to keep ME updated or active. Just let ME sit there unused. Why can't FF work with all web sites? Is the problem with them or with FF?

Hi,

I was using FF on Ubuntu 22.04.4 LTS. Had version FF 120.x and playing video in Netflix worked fine. Then I updated to FF 124.x and playing video stopped with error F7355-1203.

I've checked the DRM setting and it is enabled, I checked addons and I have OpenH264 and Widevine installed, both set to always active.

I've checked installed codecs and I do have libavcodec58 installed. No update for that available via apt. I also have ffmpeg installed, no problem with that either. I can play Netflix videos in Chrome, but not in Firefox now. Something happened to Firefox when I updated from 120.x to 124.x. Today I updated to 125.x, same problem, Netflix video won't play.

I've unchecked the DRM setting and re-checked it, and that does reinstalled Widevine but does not fix the problem.

Any ideas what could be the cause?

This has been happening for months now, on multiple devices (I have tried at least 3 different devices), and on multiple networks.

I have read the articles in here, but they just want me to check network configuration which is exactly the same for all browsers.

If I restart firefox it starts working again.

How can I prevent it from breaking randomly? This is the only browser having issues, I'm almost positive is some bug and not a configuration thing, given that it happens under multiple circumstances and devices, while Edge and Chrome simply keep working just fine.

There is no consistent repro I can give, afaik it is just random, at some point Firefox just decides to stop working and I have to restart it. This disrupts my work and browsing activities as I can lose progress on input forms and similar actions.

Firefox just stops responding when trying to load a web page. The only way to get it back working is to reboot the computer. I have tried quitting the application but when I try to restart it it doesn't respond and I end up having to force quit and reboot the computer and then it will work fine.

Any idea what's going on?

I am on a MacBook Pro with Sonoma 14.4, and the lastest version of Firefox. The YouTube website will not load. It looks like the attached screen shot. I can access the site with other browsers. I can play a YouTube video with Firefox if I have a link, but I cannot see the rest of the page - just the video itself.

I have two audio device plugged in. firefox only outputs to the usb devise even though i have selected the aux out on windows. all other programs use the selected audio out but not firefox

any help would be appreciated

Here's a quick reminder that you can keep you favorite indie browser just one click away.

Open my links with Firefox

Not now

My customer has a problem since about a month on Firefox (using it on a Terminal Server). The top of Firefox gets hidden by white and grey "bar" and he can not even use the "functions" of buttons behind that. -> Please see attached Print screens Lower part of the Favorites-bar is visible and also works if he clicks on it - everything above not visible and does not work for clicking.

The problem only comes up from time to time maybe once or twice a week. When he minimizes Firefox the application behind is visible normally. when he maximizes it again, same problem still visible in Firefox. When he closes RDP Session and reconnects - the problem disappears. When he turns off the monitor where Firefox is visible - Firefox gets move over to the other monitor and the problem disappears.

I am not 100% sure if this is a Firefox problem or Remote Desktop Problem (or maybe an add-in problem). But until now it only happened on Firefox!

He is always on the last recent version of Firefox, we just updated today to the latest version again - but I can not say yet, if the problem would still exist on the latest version from today.

Hello,

I have encountered a recurring issue specifically with Firefox where SVG images fail to display unless a pixel-defined height attribute is explicitly set. This behavior contrasts with other browsers, which handle SVG scaling seamlessly, typically adapting to the specified width or inheriting dimensions from parent elements.

During our website development, primarily through Elementor and leveraging Flexbox in a WordPress environment, this discrepancy becomes evident. The issue persists exclusively in Firefox, confirmed through extensive testing across various browsers and OS's with multiple SVG files and sites.

For diagnostic purposes, I recommend conducting controlled tests with SVG images embedded with our current setup. Set the SVGs to 100% width without defining their height and observe how they render in Firefox compared to other browsers. This should help ascertain whether the behavior in Firefox is anomalous.

I am assuming it may be with the way the markup of the SVG is rendered as it doesn't happen with all SVGs, however, other browsers appear to fix or override whatever is getting in the way from rendering...it is a strange issue.

I have included two images as an example. As you can see in the first image, the SVG isn't rendering (in Firefox) , but does render in Chrome/Safari. It only works when I define a height in px value on Firefox.

Please let me know if further information is required or if any specific steps need to be undertaken to address this issue.

Thank you.

Hello,

I added a browser extension Search by Image by Armin Sebastian some time ago and it worked just fine till recently. Now, every time I need to find some image I get the page with cute creature sitting and fishing in bucket of water with info stated: "Your search did not match any documents. Suggestions: Try different keywords." (screenshot attached). It happens every time, no matter what kind of image I'm looking for. I also added another extension Search by Image on Google by Gustavo Silva and it's the same issue.

Would really appreciate any help with it.

Thanks,

Magdalena

Recently Firefox always has the error "failed to check for update". I have tried restarting my pc and running as admin. I am on windows 10.

I have been able to manually install the latest version by installing it over the top of my current install, how can I fix the error to be sure that my browser will auto update?

Thanks

I am using the credit card autofill function. I select a card and payment is taken from a different saved card. I have quit and restarted Firefox but still wrong card used???

For some time now, e-mails have been arriving with a delay, e.g. from April 15, they arrived only on April 18. The mail is on the home.pl server pinned via IMAP.

In the Firefox settings, it says "Account disconnected" so I click the sign in button, it opens the Mozilla website, and I successfully sign into my account online. Yet the browser still says disconnected. I've tried a few times. How do I fix this?
