Firefox 技術支援討論區

Reinstalled Firefox after a computer upgrade and now I'm stuck with a disconnected account and a sync loop. I login and it shows login confirmed but I look in the top right corner where you access your account and it shows that it's disconnected. On top of that, I backed up all of my tabs, favorites and passwords but I don't have the ability to import it from the back up. I'm only given the options to import from another browser. Any help in this matter is greatly appreciated.

Hello, I am finding that Firefox display incorrectly and out of sync the subtitles in streaming services like Hulu or Amazon Video. Subtitles dialogs appear around ten seconds before the actual audio plays that dialog. It doesn't occur when I am using Chrome.

Thanks.

I no longer can use Firefox after years of being an avid user and supporter. I have followed all directions to enable the u2F extension. Have gone as far as reinstalling firefox. Are you going to fix the issue? If not I must discontinue which makes me sad.

Lately for the last 3ish days my YouTube connection speed on Firefox and only Firefox has been terribly slow. So slow that it can't even watch normal HD content. But not always, sometimes it does work at normal internet speeds which is so weird. I have around 500 Mbps download speed internet so I know it's not the issue. The picture with the slow download speed is on Firefox and the fast/normal download speed is on Chrome. Sometimes in a private window Firefox runs at normal speed but not always, I don't think it's an extension issue.

I've been having a weird issue with my text glitching only in my Firefox browser. Initially I thought it might be my monitor but then I realized the issue only presents itself in my Firefox browser. Literally no other program is affected.

I've done a reset, I've uninstalled and done a clean install, I've deleted all Firefox files and re-downloaded the browser. The issue immediately pops up again.

recently got new hard disk installed , and using moyilla as browser ...previously i could shut down and get back to tabs and sites i was using on restart .... now i dont have that view and just get a long list on recently used tabs in toolbar,mozilla icon. How can i get those closed webpages, sites, back on screen all at once ? the history optionin side menu doesnt show any way to do this either...( i think it used to ) thanks calgar.

I view a page, for example, news.yahoo.com. I usually scroll down a way, possibly to the bottom. I step away, and when I come back I want to refresh the page. Up until about two weeks ago, when I press F5 to refresh the page, it would automatically scroll back to the top of the page. Now it seems to go to (maybe) a percentage of the page based on where it was last scrolled. I then have to manually scroll back to the top to see the latest headlines. Was Firefox behavior changed? Is there a setting to control page refresh behavior?

Firefox crashes whenever I paste something in search bar. Even if its one word only. It has been like 3 months now and no help. It even crashes in troubleshooting mode. I have reinstalled and refreshed, but it helped only for a day.

Thanks in advance.

Dear Sirs,

today i did lockout everybody on a test server of a web application while playing with CSP on the server side. no modern browser was able to open the page anymore. but the real problem was that the configuration interface was also not accessable anymore.

the option security.csp.enable is long gone since FF 99 and i had to ""downgrade to FF 98"" to be able to access the misconfigured server.

please enable that security.csp.enable in about:config back again at least for the development version of FF. someone might need it. other options are to install risky extensions and i would like to avoid that in the future.

Yours

Hello Firefox,

When loading a page I work on, I sometimes see something like this:

14:54:44.103 Error in parsing value for ‘margin’. Declaration dropped. instantiate_obj.php (With a yellow-ish triangle with an exclamationmark in front of it)

The warning is clear: somewhere in the html/css a faulty margin-value is used.

But how to find out where, or what causes it?

Is it something inline, an external CSS, something dynamically added by javascript?

What I tried:

1)  Clicking on the link on "instantiate_obj.php" just opens a tab in "view-source:" mode.

Not very useful. I don't see any problems on quick inspection, but the page is pretty big. I want something easier than checking everything in the source and the linked CSS.

2) Looking at the timestamp (14:54:44.103) I see it ends in 103. Maybe a linenumber?

Nope, that particular line contains only
.

3) Searching https://developer.mozilla.org didn't shed any light on how to approach this problem.

I can only find out references on how to do it when you see the yellow-ish triangle in inspector, in the second pane (css with that 'filter styles' on top) I already checked my external stylesheet and it came out fine.

Does anybody know how to find out what caused the warning?

===========================

I asked also on stackoverflow but didn't get a response, so for reference:

Thanks for your time!

I have been using Firefox and GoToMeeting for years, suddenly this month (July 2023) I get the following message when I try to open a GoToMeeting session”

“Sorry, this browser isn’t supported. Join in your browser by opening the link below in Google Chrome or Microsoft Edge.”

I don’t want to use either of those browsers.

What can I do to keep both Firefox and GoToMeeting?

PROBLEM ACCESSING MY GMAIL VIA FIREFOX

My wife and I both have (separate) Gmail accounts – we access them on Win 10 computers, using Firefox. I have set up two Firefox “buttons” (one for each Gmail address), both of which worked perfectly – until today!

Now, when I click on EITHER of the two Gmail “buttons” I get ONLY my wife’s email! I CAN access my own Gmail with either my Android phone OR using the Edge browser however!

So far as I can see, nothing has changed with the two URLs (a different one for each button) – I’ve tried setting up a ‘new’ button from scratch and just using 'my' URL in the search bar but both still give the same result – my wife’s email account!

HELP!!

So I have the latest version of macOS Ventura, the latest version of Firefox, and the latest version of Roblox. Whenever I try to open a Roblox game from their website (yes, I know. Roblox now has the desktop app so you don't need the website to open a game), it opens the app, but not the link, which means it doesn't open the game :( Does anybody know how to get Firefox to open the link and not just the app? (Btw no hate on firefox)

I use multiple Firefox profiles. I would like an EASY way to see the name of the Firefox profile somewhere on the screen. The attached image shows a theme I created which shows the name of the profile on the menu bar. I forgot exactly how I did it, but it involved typing this in a Word document, taking a screenshot and turning it into a jpeg, crop the image, upload it as a theme, then test it. Repeated several times until I got it to work.

I don't need or want fancy graphics here. I just need the name of the Firefox profile to appear somewhere in the window. In my fantasy world, there would be an option to include this name in the window Title bar.

On a new website or after clearing the cache and cookies and upon opening a page I will often get a pop-up with cookie usage choices, e.g. "strictly necessary", etc. However, the pop-up disappears before I have a chance to click on any choice or even finish reading the first line. I'm not sure what settings I need to change to allow me to make a choice on the pop-up. Please advise. Thanks.

I am using Firefox 114.0.2 address bar only, no search bar. I do not remember when it was happened, but today when I want to copy and paste page address I found out that address bar did not display the page address as previous version, just display the words I searched as a search bar (if the search bar is enabled, and typed in search bar then push enter, address bar will display address of search result page, and search bar will keep displaying the words in it). I attached my screenshot below. Using another tab and "switch to tab" feature by Firefox, I found out the page address. In my screenshot, I typed "test" and using Google to search (I also tried Bing, Wikipedia and more and all of them have the same problem with their owned link) and the page address should be "https://www.google.com/search?client=firefox-b-1-d&q=test" but even I paste this link into the address bar, it will only display "test" like the pic. I think it is a trim feature but I do not which preference I should edit in about:config. I have set "browser.urlbar.trimURLs" to false for displaying http and www, but it is not work this time.

Hi, I am working on websocket with javascript and php. Let me share my code here:

index.php is:

        // Function to save message on the server
        function saveMessage(message) {
          const xhr = new XMLHttpRequest();
          xhr.open('POST', 'save-message.php');
          xhr.setRequestHeader('Content-Type', 'application/json');

        // Fetch messages when the page loads
        fetchMessages();

    );
    $server->run();

The websocket is working all the browser except only firefox. It gives error: Firefox can’t establish a connection to the server at wss://cstechnologyindia.com/websocket1.

I am trying to solve it from past 2 days. I'm using a shared hosting. The hosting provider is saying that everything is perfect from our side. Now I'm hopeless. Please solve my problem anyone. Please check added image. Also I've valid https certificate. Please check attached image.
