Diễn đàn hỗ trợ Firefox

When I try to play a video on Firefox desktop, it takes it a long time to load. Once it has loaded, whenever I pause it for more than a few seconds, or if I try to skip around the video (either by clicking around in the loaded section of the progress bar or using +/- seconds buttons), the video begins buffering again before the video resumes. This makes it extremely difficult and frustrating to watch anything that requires me to pause, rewind, or fast forward. I've noticed this issue affect multiple video viewing sites, such as YouTube, Vimeo, and Netflix. My roommate also uses Firefox, but doesn't have this issue, so I know it's not a problem with my internet. I thought it might be a problem with my computer, but I tried to replicate the issue in Chrome and everything worked fine there. The issue has persisted almost a week. I have:

• Rebooted my computer several times
• Deleted my history/cache
• Disabled my extensions
• Turned off Java scripts in firefox (this disabled my ability to load sites like YouTube completely, so I turned it back on)
• Updated my computer
• Updated my graphics drivers
• Refreshed firefox
• Uninstalled and reinstalled firefox (and rebooted my computer)
• Uninstalled and reinstalled firefox AND deleted all the data it stored on my computer (and rebooted my computer)

I am currently using version 123.0.1 of Firefox. My OS is Windows 10 22H2.

how can I restore to white, the black background on the Firefox Browser, even my menus have turned black. I have tried through my normal settings and although it states I have a white background. It doesn't

Firefox updated and now my tabs are above the address bar, I hate it. I have went through all the information I could and created a new chrome folder, downloaded the css and changed user preferences but it sets the tabs to the bottom of the screen not just below the address bar. I think I need a different set of code for the css but cant find a copy. Does anyone know what to do?

I'm hiding menu items using userChrome.css with option “toolkit.legacyUserProfileCustomizations.stylesheets” set to “true”.

So I am hiding some menu items like for example

1. menu_find { display: none !important }

however though the menu item is gone how do I get rid of the ctrl-F menu shortcut...

I have many such menu items to remove so I need a generic solution to override the short-cut icons associated with the menu items I want to remove

How to allow web page to override a keyboard shortcut. Currently firefox picks up the shortcut instead of the webpage...

For example I have an webpage that detects ctrl-shift-h which worked fine in version 56 but now in version 96 it brings up a "Show All History" dialog

I an doing many such things so I looking for a generic way to override firefox keyboard shortcuts

Firefox does not print the right edge of web pages that are made in landscape mode.

I set FF to "Fit to page width" but it does not print the right edge. It's cut off.

And there is no Orientation option available. Not sure if that has any significance because it supposed to "Fit to page width" anyway.

What's the work around to fix this?

My work consists mainly of capturing accounting data online. It is important that the browser warns me if I try to close or navigate away from a page if the data entered has not been saved or updated, but I no longer get these warnings.

Please help.

I've tried going in safe mode, turning of my Facebook container. Deleting cache. Signing out of Facebook. Also adjusting the backspace key in my Config. Having no problems on my Android phone or when using Opera. It's on on Firefox and on Facebook.

FACEBOOK screen suddenly moves to the bottom of the screen when I am typing a comment. Whenever I hit SHIFT+alpha_letter at the beginning of a line OR simply hit the backspace key, the screen suddenly shifts to the very bottom of the page again even if I have tried to scroll the page back up to the middle of the screen manually. This shifts the entry area where I'm typing down and sometimes off of the visible screen entirely. Just hitting the backspace to correct a typo causes the screen to scroll on its own. I have to scroll back down to the entry box and if I make another typo, it happens again. 

Please help. Been going on for over two weeks. I was hoping the new Firefox update yesterday would help. Nope. Still happening.

Hello, since migrating from Chrome to Firefox, I have used the Import Wizard to successfully transfer over my bookmarks and history, but I just can't seem to get my logins/passwords over. The wizard finishes saying that it successfully imported saved logins and passwords, but nothing shows up in the password manager. I am running Windows 10 64bit and Firefox is up to date. Anybody have any suggestions?

Thanks

Hello,

the newest update to version 97.0 was run automatically. Afterwards the new print preview appears although I have it disabeled in about:config (print.tab_modal.enabled --> false). I cannot get rid of it. It is very annoying as I cannot print my labels with that menu and always have to click once more to do so. Does anyone has a fix for this?

Thanks in advance,

Thomas

I use to be able to change firefox icons by adding these files in Firefox under the browser directory

chrome/icons/default/BrowserPreferences.ico chrome/icons/default/CustomizeToolbarWindow.ico chrome/icons/default/default.ico chrome/icons/default/downloadManager.ico chrome/icons/default/main-window.ico chrome/icons/default/openLocation.ico chrome/icons/default/places.ico chrome/icons/default/printPageSetupDialog.ico chrome/icons/default/TabMIxPreferences.ico chrome/icons/default/unknownContentType.ico chrome/icons/default/viewSource.ico chrome/icons/default/Wizard.ico

It worked in version 56 but now in version 97 and this no longer works?

I'm using Firefox 85.0.2 . . . I was doing this (below), to customize my header and footer, but in this version of FF, I no longer see this in Options - only in: about:config . . . keyword "footer" . . . there, I would have to change it for 5 different ways of printing (to printers or to PDF)

I need to get rid of printing the URL in the footer - many times, it's too long, and I don't need it.

Where did the Page Setup option go?

I see in the current Print Options, you have to go to - More Settings / Margin / Custom - to see those. Why would they put this so many levels down?

It used to be: File / Page Setup / Margins & Header/Footer . . . "Customize" Headers & Footers:

Option 1 (left) . . . there are two leading spaces:

 > > &T
 > > &U . . . &D . . . &PT

Option 2 (left) . . . get rid of the ">"s, and just have the two leading spaces:

 &T
 &U . . . &D . . . &PT

I paid Firefox $28 for unmarked videos. Now the mark, the stamp in the corner of the video, is back. I would like my money back or the non-stamped videos back. Who do I see about that?

In Settings/Applications, have "JNLP file" set to "Use Java(TM) Web Launcher (default)". This is used in Oracle's Agile to view documents. In previous versions of Firefox when selected, the file would open using Java to display the document from Agile. As of Firefox 97, now only "Save File" or "Cancel" options are offered. What happened that this functionality has been removed?

I cannot watch a video on youtube when it is in the process of being live streamed. I remember a time when I was able to, years ago, but I can't any longer. I'm not sure what has changed. I found an article that says to install the optional update called "Windows Media Pack" in apps and features, but no app with that name exists. It was only a year old solution, so I'm unsure of what changed so significantly. I just installed another optional windows update, and also updated the browser, but still doesn't work.

Firefox: 97.0 (64-bit)

When I am not in full screen the minimize, maximize and close options are there. They disappear when I go into full screen and I am forced to get out of full screen to minimize or close firefox. This only started happening recently. Does anybody know how to make these options appear again while in full screen?
