Firefox 技術支援討論區

I've been implementing my own file hosting / streaming platform and managed that my solution performs a lot better in Chrome compared to Firefox. Of course the actual download speed is the same, but it seems firefox buffers a much larger byte range before starting to play the video compared to chrome.

For example, the first screenshot shows network traffic in Firefox between opening the page until the second the video starts playing. As you can see, Firefox loads 346.58 MB of data in 19.01 seconds (including one 326.70 MB range request for bytes 19365888-5071292588/5071292589) before the video starts playing. This results in almost 1 minute of video to be buffered before playback begins.

Whereas in chrome, the video starts almost immediately after only buffering smaller byte ranges (as shown in the second screenshot). What's interesting is that chrome seems to request the entire rest of the video immediately after but keeps streaming the received bytes instead of waiting for the entire range request to complete, so the last request in the third screenshot just keeps growing in size while the video plays.

I was wondering if there's something I could tweak on my end or if this is something that could be improved in Firefox. It seems odd that Firefox buffers such large chunks of videos before playback begins.

The fonts are weird for some pages. I have used the following settings: Fonts for: latin, Proportional: Serif, Serif: Default(DejaVu Serif), Sans-serif: Default(DejaVu Sans), Monospace: Default(DejaVu Sans Mono). Also I have checked the box "Allow pages to choose their own fonts, instead of your selections above".

Need help to fix the issue!

Hi

I exported all my firefox passwords to a csv with the option in about:logins.

Now i wanted to reimport them and set signon.management.page.fileImport.enabled = true, restarted firefox, opened about:logins, menu option import from csv is present, selected the exported csv and nothing happens.

There is no error massage. A you seriously telling me that since lockwise has been abandoned about 2 years ago that there is an option to export the csv but NO freaking possibility to import it?

How for god sake should i get my >500 Passwords back into firefox?

Chrome does import the csv exported by without a hassle by the way.

So I can not play audio from any website in firefox. I updated, refreshed, used troubleshoot mode, and unistall & reinstalled. Nothing works. I know it is not my PC because the sound works on every other app, just firefox wont play audio PLEASE HELP

I have been using Firefox for many years. Suddenly I cannot get any sound from videos in Facebook, YouTube or anywhere. The settings in Privacy --> Permissions --> Autoplay are set to "Allow Audio and Video". There is nothing wrong with the computer as I can play videos and sound files on it with no problem. Sound is no problem on Internet Explorer or Microsoft Edge. It is just Firefox that after years of use the sound as stopped working. Can anybody help?

Playing back 4K YouTube videos on macOS uses software decoding, when the only GPU available is from AMD, despite the GPU being capable of VP9 decoding. Unsure if macOS's AMD drivers just don't have VP8/VP9 decoding baked in at all.

On my Windows 11 desktop PC, desktop Internet shortcuts created by dragging and dropping links are white squares with a small icon inside depicting the actual website logo. I don't know if this intended behavior or a bug.

I have Logins & Passwords (about:logins) as a bookmark in my toolbar. Sometimes you need to look up a password. I opened about:logins in a new tab and there is nothing there. No content, whatsoever.

I AM logged into Firefox. No, I haven't installed any security features recently. My history and my bookmarks are all intact. When I go to a previously visited site, I DO get the prompt for my user name and it DOES supply the password. It's only about:logins where no data at all is displaying. I can't search, it isn't showing me anything.

I tried to export passwords from about:logins but it didn't work, that is, I thankfully actually remembered my Firefox password and it prompted a csv download, but nothing was saved (presumably because there is no content within about:logins) to generate into a csv.

Now what?

Trying to open any link from a pdf opens a page with the url resource://pdf.js/web/ instead of opening the link. The attached image shows what the page that opens looks like. This does not happen on Edge, so it is a Firefox issue.

I have updated to the newest Firefox version and the issue remained the same. I tried clicking on "viewer.html" and it brought me to an empty pdf page that just loads forever and cannot be downloaded.

Please help. I do not want to use Edge or go back to Chrome, but I will if this can't be resolved.

Hello, From FF 99 I have removed the floating tabs with CSS code but after updating to 104 instead of the active tab being differentiated with a shadow it now has a black border. Is there any way to change that back while still keeping the CSS code I have for the floating tabs?

The code I have is: .tab-background{ border-radius: 0px 0px !important; margin-bottom: 0px !important; } .tabbrowser-tab:not([selected=true]):not([multiselected=true]) .tab-background{ background-color: color-mix(in srgb, currentColor 5%, transparent); } .tab-background{ border-color: transparent !important }

Thanks.

After the introduction of Safari years ago, I have finally recently switched to Firefox. I like it, but the font thing is about to send me packing. I just cannot get a decent automatic display of all websites. I never had an issue with Safari. Example: Gmail's body section is way too small, no matter how much I try to enlarge it, it just doesn't want to enlarge. I mean, this is really a hassle. Is there a simple setting in Firefox that can duplicate Safari's handling of text/fonts? I really would like to use it as my default browser, but it's really getting annoying.

Using a desktop with Windows 11 OS. Google search is not working in Firefox, but works fine in another browser. Have also noticed I was getting several sites I normally visit were asking me to validate that I was a human. I have cleared the cache and cookies, but did not help.

Yahoo mail Cannot select a message using the checkbox. Cannot reply, delete, etc. Trash icons are missing All works in Google Chrome. Clearing cache/cookies, restarting computer, nothing works.

Hello,

When I open a email which contains an url like https://link.domain.com using sendgrid.com's service, I get a SSL_ERROR_BAD_CERT_DOMAIN error.

An example of such an url is https://link.intersport.fi. The domain starting with link is a service provided by sendgrid.com to be used in email advertising.

The issue is not specific to intersport.fi but to any domain using sendgrid's link service.

The strange thing is that Chrome and Edge are totally happy with link.domain.extension.

What is your take on this?

Best Regards, Thomas

Getting sick of FireFox, I want to search from the GOOGLE SEARCH BAR, not the address bar, but the settings don't work you can choose to have the search bar next to the address bar, but it doesn't work, the google search bar doesn't work either, no matter what setting, your search ends up in the address bar, with all the updates, they don't fix crap on here, when someone makes a complaint, FIX THE CRAP, I don't need to ask 100 people why it wont work, just FIX IT!!

As of yesterday, 9/4/2022, I cannot access YouTube or search anything on Google. The YouTube issue was supposedly fixed with the most recent Mozilla FF update, but it doesn't seem to be working. I cannot load YouTube or search for videos if the page does load. I cannot reach the Google page and I cannot search using the Google toolbar extensions.
