Форум поддержки Firefox

Hi,

I've been encountering a strange issue where colors (especially whites) in the video player are super washed out. This only happens when HDR is turned on in windows, and only happens in my Firefox Developer Edition installation (normal firefox works fine). It also doesn't show up in any windows screenshots - the colors revert to normal when I'm in the screenshot GUI. I've attached photos below of a youtube video, the left is firefox DE and right is normal firefox, both in and out of the screenshot GUI so you can see the difference.

I'm on Windows 11, and I'm not sure what caused the issue. I've tried both refreshing and reinstalling firefox DE to no avail. Pretty stumped on this one, and would appreciate any help!

I like to mute all of my tabs so they don't play annoying sounds. However a very annoying mute icon appears when I hover over it and the "muted" text is shown under the name. I tried adding to my userChrome.css:

@namespace url(http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul); .tab-icon-overlay[muted], .tab-icon-sound[muted] {

 display: none !important;

}

This only removes the muted icon, and when I hover over a tab its favicon disappears. I also tried changing browser.tabs.showAudioPlayingIcon as suggested in [answer] but it isn't an option anymore.

How do I remove it completely without changing the context menu item?

Lately in Google Drive I get this error when I select one image or a file: Impossible load details. Retry. I have Firefox 108 version, on Edge and Chrome all is OK. Also the troubleshoot mode doesn't resolve the problem.

The blocks where code should be displayed like on screen and on stackoverflow displayed in a weird manner : replaced with [Object object] i don't have any extensions that might cause that

Hello,

Please add this feature in Firefox and Firefox developer edition

I am wondering when i open firefox developer edition. All the tabs will be open during stating firefox developer edition.For better understanding this feature is already in google chrome.Please search this in google

Open a specific page or set of pages

I use Firefox Developer Edition and recently I noticed a problem when watching videos on any website in full screen mode. As can be seen on the attached image, there is a weird pixelated border around the video.

Every time I go to Fox News, the video at the top of the page drops to the lower right-hand corner. It's an annoyance I've been searching for a way to eliminate. I have pop-ups blocked in preferences and I have a couple of different pop-up blockers, but nothing seems to work. I'm currently using Firefox 114b.09 on a Mac Desktop.

I've got about 10 bookmarks with links to support pages each about adjusting specific about:config setting to my needs. My job also requires me to change systems lots of times, from Mac to windows to Linux. Is there an easy way I can save my personal about:config changes to a file for easy import on other systems?

Thanks

A few days ago I was downloading a ZIP file and was warned that "This file contains a virus or malware". Fine, thank you for telling me but now how do I seeing the same warning every time I start Firefox? The file in question does not exist on my computer so far as I can tell and I did a thorough search through 3.5tB of storage on the machine to make sure. How do I stop this warning?

When I copy text from other websites, I'm not able to paste in the text field of Whatsapp Web. I'm using Firefox Developer Edition Browser in my laptop. But when I copy text from Whatsapp Web itself, I am able to paste in the text field.

This issue started happening just a few days ago.

Here are my specifications:

Browser: Firefox Developer Edition 117.0b8 (64-bit)

OS: Pop!_OS 21.10

Hello,

Currently running MacOS Montery but the problem was still occurring on previous versions.

Whenever I use the green top left button to enter full-screen, the app immediately freezes and either crashes or has to be manually force quit. There are no reports in about:crashes and I there has been no success with troubleshooting mode or switching versions of the Firefox application.

Machine Info: MacBook Pro (16-inch, 2019) Processor: 2.6 GHz 6-Core Intel Core i7 Memory: 16 GB 2667 MHz DDR4 Graphics: Intel UHD Graphics 630 1536 MB

Any help towards a solution would be appreciated. Thanks!

I have used Firefox with my Outlook email account for years. This morning when I open my email it displays the message list briefly then goes to "Something Went Wrong."

Microsoft has confirmed it's not my computer and not on their end.

Updating to latest Firefox does not work.

en-US: My Browser Firefox Developer not enter mode Mobile with CRTL + SHIFT + M. Clicked f12 and click smartphone ok. Comand Allowed, more not apply Version 96.0b3 64bit

PT-BR: Meu Browser Firefox Developer não entra em modo Mobile com o comando CTRL + SHIFT + M. Clicando f12 e clicando no smartphone funciona modo mobile. O coando está selecionado, mas mesmo assim não funciona. Version 96.0b3 64bit

I'm not sure this is a problem with Firefox but I have run out of other options to look at. At first I thought it might be because the page uses a frameset (I know it's obsolete) so I created a version that uses an iframe instead. That way the html that needs to be acted on is not in a frame. It still doesn't work. I don't know why it works in stackoverflow's sandbox and jsfiddle but not on my website. Any help is appreciated.

Frameset version iFrame version

If you need to see the tabstrip code (it's virtually identical to the iFrame version): Tabstrip for frameset version

The script is supposed to hilite the selected tab with a red background. The rollover works fine (yellow background and brown text) but the selected tab color never shows up.

The URL in the URL bar is trimmed. I went to about:config and disabled "browser.urlbar.trimURLs", but it still did not work after I restarted Firefox. (see images)

Firefox version: 105.0 (on beta update channel)

I later then found out that there is a lot of unused space on the right. (see https://1drv.ms/v/s!Ag9_47ED3j7sgsZhkB02k7gI3lavyg) How do I remove / make use of the space on the right of the URL bar? How do I turn off the trimming of the URL?

Any help is appreciated!

I use HTML files to create images for a tile based game we play. 6 months ago I was able to create a table with collapsed borders and 0px padding, margins, and borders, then draw my image with 207 x 207 JPEG TDs in multiple TR rows, then place another GIF image over all the JPEGs with transparent edges. Doing this for a table that was 6 tiles (207px) wide and 4 tiles deep, at ctrl 0, displayed a Firefox combined image that was exactly 1242px x 828px that was completely visible on 24 inch 1920 x 1080 DELL monitor. This allowed me to right click an empty space on my Firefox screen and select Take Screenshot to click on the GIF overlay image and capture that image with all of the tiles that were behind its transparent edges.

For some reason, I have no idea why, my 207px by 207px tile images are now being displayed as 282px by 282px at ctrl 0, and the overall image is now too large to fit on the screen, so taking a screenshot of the proper sized image is no longer possible. For example, at ctrl- ctrl-, the tile images are 221 pixels square, which should be 1326 pixels wide for 6 tiles, but my 1242px wide GIF file displays at 1330 pixels wide, probably due to some kind of rounding error.

I was able to use about:config and change layout.css.devPixelsPerPx from -1.0 to 0.74 and it did solve the problem. But it does so with a lot of warning for changing that default value!

So my question is simple: how does Firefox, on Windows 10, determine its screen pixel to Image px relationship? I need to know what to look at for the proper way to get my px to pixel ratio back to 1 to 1.

This is what the working image looks like while designing the center scoreboard tile https://user-media-prod-cdn.itsre-sumo.mozilla.net/uploads/images/2022-08-23-13-36-34-2fa67f.png

and this is what the final image looks like when you take a screenshot of the image https://user-media-prod-cdn.itsre-sumo.mozilla.net/uploads/images/2022-08-23-13-36-53-beae42.png

In order to more convenient drag-and-drop interface, I need a fixed fixed space in nav-bar like Edge. For now we can add a flexible space on it. But it's flexible and it will disappear when I use a side window. And I can't drag over titlebar-buttonbox-container Please help me. Thanks!

Recently, I've started noticing these quick action tiles in the URL drop-down menu (I've attached a screenshot). There's a help icon to their right, but it just goes to https://support.mozilla.org/en-US/kb/quick-actions-firefox-search-bar?as=u&utm_source=inproduct which is a 404. I found this bugzilla bug, but I'm not 100% sure on how the versioning works (even after consulting Wikipedia). The bugzilla entry mentions it's fixed on 105.0a1. I'm using 105.0b6 of the Developer Edition.

When Firefox asks if I want to download an update and I agree, soon after that but not right away it stops working - on every new page it says "We need to restart to finish updating" <- This last bit is VERY annoying. Is there a way to keep FF working in such situation? I usually have 3 FF profiles running, about 10-20 tabs each and when it suddenly does this - I can restart them all but when it is suitable for me.

The only solution I can see so far is disabling updates via group policies (which is not well documented, where do i put this policies.json on Fedora? need to google that).

Any other ways to keep updates and FF running until I decide when to restart? Thanks.
