Firefox 技術支援討論區

I had been using Firefox browser for awhile, but because of playback performance issue, I have to using another browser just for video playing, especially for 4K video.

Compared to Edge, Firefox seems taking more resources to playback the YouTube video and more heat. When look at the Task Manager, the Video Processing is 0%, and GPU is running significantly more resources on '3D'.

An example of the problem: Firefox does not rnder the page https://www.ebay.co.uk/itm/164957094349?_trkparms=amclksrc%3DITM%26aid%3D1110013%26algo%3DHOMESPLICE.SIMRXI%26ao%3D1%26asc%3D238391%26meid%3D7ab2984ab89c490d9d19c64154175f61%26pid%3D101195%26rk%3D5%26rkt%3D24%26sd%3D402300560285%26itm%3D164957094349%26pmt%3D1%26noa%3D0%26pg%3D2047675%26algv%3DSimplAMLv5PairwiseWebNoToraCoCoViewsNoHighIdfOrSortByFinalScoreBlenderWithPromotedViewItems%26brand%3DUnbranded&_trksid=p2047675.c101195.m1851&amdata=cksum%3A1649570943497ab2984ab89c490d9d19c64154175f61%7Cenc%3AAQAGAAABQJxAynw2%252BiqzPDrRSEdA1OtGPHECjXiPIHTAGGaFXyfAhhOOcI0evIqLAV5dzxfkWlXm6ww1t0P09GMtcbSuFZjf5HidAoI3BLEE5q9IzcpZf1TZn1%252BLTOgqc1OD9sLjUiICuetx8VnxmROZ45L3noIgk65aQJuCoPA0d32OWfO52LE5XKsl22M11N9hzVfwHgluh%252F5HKiKhVl5Tsx0wb0b0dE30VWGeE6KisowiOj70Bzel9x4sBW7H8CN3vmNB2XZxJ3WwTx5I56fEAax5jK2zMEYDr0au%252Fk%252FCwLpDP%252BFvJPj2%252BRIxUzguSZgC5le17lkTY6CuGTF9xYRefAzw8ks%252FtcGsNkPKFb7ZfNXkOLe1k28NQbsvOuhPVcLk1pb3Joal6Ssw3egfQv4HF3D4vL6v6k1xWnbVepvH8lGXPENE%7Campid%3APL_CLK%7Cclp%3A2047675&epid=23034767275

properly. A lot of the text comes out in very narrow columns. The problem happens quite often on eBay. Chrome does render it properly. Could you please look into this? Thanks, Jon

Since the latest Firefox, I cannot load Bell Webmail when I am using my VPN. Everything works fine with Edge. I am not tech savvy, but is there something in "settings" that should be adjusted. Bell says that Firefox is the problem. Alan

This is a moan more than a question. About every six months or so my bookmark sidebar disappears because i have clicked Control and B without meaning to. And that is how to get it back again. Except, I never remember and search all over the page (View, Options etc) without finding how to get it back. So I eventually do a search for how to recover it and find all the archived guides from when other people had the same problem and the same question and ther same frustration. So my moan/quesion is this: why the blankety blank, doesn't Firefox add something into the menu (View or Options or somewhere) that says "Show toolbar permanently". Would save all this frsutration and irritation. The impression I get is that Mozilla thinks we should not want to have the menu on screen all the time. But that is the problem with users! We have our own way of doing things! Please!

I see instructions for sync' to a phone, how do I initially (connect) sync to my desktop from my laptop?

When I sync my bookmarks, how does is know which computer is the primary (the one that I want to duplicate changes from)?

For example, I added new bookmarks and revised some old ones on my laptop and did not have the sync on my desktop at the same time. Now, if I sync my laptop to my desktop, how does it know which device is my primary (in this case my laptop) where I made all the changes?

My goal is to revise all the bookmarks currently on my desktop to reflect all the changes I made to them on my laptop. I'd like to do it without duplicates or displaying old desktop residual bookmarks that I deleted and/or modified on the laptop prior to sync to the desktop.

In this case, should I delete my bookmarks from my desktop and then sync to my laptop so as to seamlessly & efficiently have my bookmarks toolbar on the laptop look the same on the desktop?

Thank you for your help here! Christopher

When I go to download a ZIP file, it will always attempt to download the file directly rather than letting me open it with WinRAR. When I go into the browser settings I see that some other file types have options to choose how they're handled, but there's no entry for ZIP files. I've tried refreshing my Firefox install and yet the issue still persists.

I used to have this option before I reinstalled Windows a while back (where I kept my files but not programs). I don't know for sure that that's what caused this to start, but the timing would line up.

I've noticed that when I download a PDF attachment or file firefox open the file on same tab instead of new tab.

How to I change settings to open pdf on new tab and not the same tab?

Hi! Since yesterday, in Outlook, my font size became very tiny for subjects and categories. I can barely see it. Can you please restore them to normal sizes?? I am desperate trying to read them. Thank you! Shirley Savva

I cannot play CNN videos in Firefox. They will not start. I can play them in Microsoft Edge and on my iPhone. I can play other videos in Firefox from, say, YouTube. It's just CNN that seems to be the problem. I have a Windows 10 PC.

Hi I have been a user of Firefox for many a year, and this is the first tme I've come across an intrusive problem. Since updating to the latest version, I find I can no longer change the icon on a URL shortcut. I had quite a few of them, which helped distinguish (obviously) what I might want to select. That was then. Now, I have a load of indistinguishable Fireox logos which make finding the shortcut I want imossible. On going to change the icons, I find the Website Document tab in properties is no longer there .. while I have Firfox installed. Remove Firefox and the capability magically returns. I have re-installed Firefox in case of corruption, with no change. Before I remove Firefox permanently (which I'd be loathe to do), does anyone know the cause ... or solution or workaround?

My problem is this:

If I click on the open new tab button, and then I keep my cursor there, such that I get the little tooltip "Open a new tab (Ctrl+T)..." , Firefox will stop the address bar from updating---it won't show my keyboard inputs, not will it search, or do anything else. This will resolve itself after I move my cursor away from the open new tab button and the tooltip stops showing, even my inputs will appear there.

This quite annoying, especially when opening a tab to search for something quickly...

An error occurred during a connection to www.facebook.com. SSL_ERROR_DC_EXPIRED What in the world? does Facebook not keep up with its own security? or is this a Firefox thing?

The latest example is the button to sign into LinkedIn. It is not working in Firefox, but it does in other browsers. I have other examples just from today. I have used firefox as default for many years. I assume this is a security thing, but these are basic links. I have no add-ons or other complications. Most times, I do not even realize there is a problem, but when I feel something is wrong, I try another browser and it works. Thank you.

Looking for free border designs, and have found the add-on easy search tool required for most of them. Their web site has the add-on for Firefox, but how safe is it? Thanks.

This bug occurs very randomly, but it seems there have few things in common.

- Occurring on domain level, one domain at once. For example, if Youtube.com stuck, any sub address including each video page is not loaded. Other website and whole browser works fine. - Other program on same PC is not affected, too. - Which page is stop loading is completely random. It might be happen only on a popular, feature-rich site like amazon, google, but not sure. - The timing is also random. Maybe after waking PC up from sleep, but not sure. Frequency of occurrence is once every 1~5 days. - The workaround without restarting browser is 1.)switching to other container tabs(strangely), 2.)opening website on private window. Disabling all the addon manually didn't help.

Since it's randomness, I didn't have any logs about this issue.

Firefox on PC doesn't load any sites, not even 192.168.0.1. Not even in Troubleshoot Mode Yesterday it worked.

Firefox is the only browser with this issue. Chrome and Edge work fine

Firefox on my Android phone works fine as well

I tried following these articles but they didn't help:
