Firefox 技術支援討論區

Hi, I spent several hours trying just to change the color of the downloads icon (thought it would take me 1 minute). First I tried to do it myself, then searched the internet. From what I found on the internet, some stuff doesn't work, some works partially and in an unexpected way, most of it is difficult to understand and modify. Finally I give up. Please, is it possible to make white the download pie and the arrow thing (when the download is finished). That's all I ask for. If possible, without using the var-- stuff, just using fill: or filter: or some other straightforward functions.

I added a screenshot of youtube having flickering while video is being played, it is a bit hard to see but there is a slightly brighter stripe on the grey background and picture cant depict flickering; it starts immediately after video is started and stops after 3-4 sec after video is paused, like there is some background activity behind youtube foreground. I understand my comp is weak (Intel Iris Graphics 550 1536 MB 8 GB, 2133 MHz LPDDR3), but not that much, please help

I recently refreshed Firefox and now I am having trouble streaming some news channels from my TV provider. The message I get is "FIREFOX IS INSTALLING COMPONENTS NEEDED TO PLAY THE AUDIO OR VIDEO ON THIS PAGE. PLEASE TRY AGAIN LATER."

I went to my Settings under DRM and found some articles on how to watch DRM content. I dug a little deeper and went to Manage Your Plugins and noticed two Enabled Plugins - OpenH264 Video Codec and Widevine Content Decryption Module provide by Google.

Under the Widevine plugin, there is a message highighted in yellow that reads - Widevine Content Decryption Module will be installed shortly.

It's been like this for 2 days and I don't know what to do next.

Hi,

I have a problem with youTube. I've always been able to access my channel sections simply by clicking on the section title with no issues. However, since last night, that is not working. Now, the only way I can see all the playlists in each section is if I right-click and open in a new tab.

Any ideas what's up? As far as I'm aware, it's not a connection problem and I've cleared the cache etc. Using a Mac.

It's a real pain having to open sections in a whole load of different tabs. Any pointers in the right direction would be much appreciated! Also, I'm not very tech-savvy :(

Many thanks, Maroulita

On all windows in Firefox, both normal and private, I get what looks like brushstrokes over the text. Generally they disappear when I move the cursor, but they also appear and disappear without mouse moves. I have the same extensions running on other PC's but don't get this happening, only on this newly-built PC. Using Windows 11 version 22H2, Firefox ESR 115.4.0 64-bit. In the sample the brushstroke shows about 80 % down the page. It disappeared after about 30 seconds, and other appeared later. While writing this, the same kind of thing was happening on this page. Extensions Ecosia and Ghostery.

hello

since few years im a bit surprised by the fact, that on firefox, it's harder and harder to do the following customisation : -enable or disable javascript -enable or disable pictures of webpages

the thing is, years ago it was just a one-click setting to change, and now it's looks like to be needed either to go on nerdly-menu (about:config, and know by heart the right one), or to use an addon (that i dont want)

do you know if there is a possibility, for an offline computer (mean bye addons), without going to about:config, to enable/disable both Javascript feature, and picture of webpages?

it's the same for customised search engine : years ago it was faisable with just entering the address of a new one into the common settings, now it's looks like an addon is required.... why?!

years ago no addon nor connection was needed to : -en/disable JS -en/disable images/pictures on webpages -add/remove search engine

..why?

thank you vm

Hi.

Is there a way to display a column in the bookmark manager (Ctrl+Shift+O) which would show in which folder each particular bookmark is?

Is there a way to search for bookmarks (in the bookmark manager or the bookmark sidebar (Ctrl+B)) by specifically excluding certain (bookmark) folders (e.g. MySessions, Save for Read Later, BSP2 trash folder, etc)?

If the above is not available, please kindly consider those ever since important features.

Thank you very much :)

Constantly seeing websites loading with these unusual fonts. I deactivated the setting which allows websites to render their own fonts and have disabled seversl add ons with no resolution. I am on Mac OS 14.2

If I lock my machine for more than a few minutes and then log on again, it's always the same. I unlock my system and feel some kind of slowness in Firefox. When I switch from the currently open tab in Firefox, the new tab is highlighted in the tab bar, but the content part of the window is frozen. If I quickly open htop, I can see that the main Firefox process is suddenly using about 130% of my CPU. The only solution I have found is to quickly open htop after unlocking the system, send a SIGKILL to the main Firefox process and reopen it. This way the freezing, slowing problem is nowhere to be seen.

I am running Debian 12 with Firefox 115.4.0esr (64-bit). I have more than enough RAM and CPU.

Hey there,

Starting with Firefox v115, you had to set layout.css.page-size.enabled to false in about:config to get the page orientation back for printing PDFs (i.e. Portrait or Landscape).

It seems with the release of v119, this once again is broken and the layout.css.page-size.enabled setting no longer works. Is there something else that needs to be done now? We rely heavily on this and our current workaround is installing the ESR version of Firefox but seems like it'll catch up eventually.

Any help would be greatly appreciated!

Thanks!

Hello! I have been inspired to customize Firefox to make it look like version "4" from this reddit post!

One of the things that I cannot find is how to get the old Firefox 4 icons. Is there an official site that has them or should I search or the source code of Firefox from version 4?

I like to save things and later go back and watch on Facebook. Lately I can not save anything. But I am able to save on my I Phone. Have I messed up my settings some way?

I've been noticing a consistent issue specifically with Firefox causing my mac to black screen/shutdown involuntarily.

It happens specifically when I use the zoom-in function on firefox web pages (the pinch zoom).

Other times when it doesn't black screen, firefox would sometimes have this pixelated appearance (basically random squares interspersed around a web page at times) after I try zooming in.

Anything I could do to help prevent this problem?

I use Spanish/English dictionaries. I also use Web sites in English and in Spanish. I want spellcheck to detect the language and enable the proper spell check. I always had that ability in Safari, for example.

Necesito ayuda! You see; it doesn't work.

Thank you for any help!
