Diễn đàn hỗ trợ Firefox

hi, something happened to my themes. i can no longer see the preview/thumbnail of them, also the authors link is gone. i've been trying everything for hours, but couldn't find anything in about:config that worked. any help would be great, thanks!

Hi, i am on linux an Firefox 115.0.2. Every supported website appeared in dark mode because of my preferences in the firefox settings respectively about:config layout.css.prefers-color-scheme.content-override is set to 2 and my system mode is dark. (0 and 3 changes nothing) Since some time this settings does not work anymore. The only thing i have changed is: about:config - privacy.trackingprotection.enabled set to true So now all the websites appeared in dark mode now appear in light mode. Chrome shows all these websites in dark mode. (But of course thats no option :-)) An Example: reddit.com: before: dark, now: light mode, Chrome dark mode. So please help! regards, awilli

I have tried syncing to the time server and manually updating the time with no success. It is only happening on this computer. My other laptop and my Android are fine, so it has something to do with something on this PC. I've tried to disable vpns but that hasn't helped. Any insight is greatly appreciated since the timestamp is crucial for much of what I do!

Hi,

I have Firefox 102 ESR in Debian 11 (LXC in Chrome OS). It is the en_US version with Czech spell checking dictionary installed as an add-on. I can switch the spell checker from English to Czech in ordinary text areas by accessing the context menu via a right mouse click.

However, I'm using a proprietary e-commerce system (Shoptet) with a WYSIWIG editor that has its own context menu, overriding the default one in the browser. I can't switch the language for that reason. Is there a way to switch the spell checker language for a particular text area without access to the context menu? Thank you very much.

My problems started after the upgrade to 113 when Firefox would no longer load at all. I tried deleting and reinstalling, but nothing changed until I moved the profile (yeah profile mgr didn't work either). I finally got it to reinstall and ran sync but had to also reinstall my extensions/addons. The extensions appear to be working, but the are not displaying in either the toolbar area or in customizations.

I have tried searching all over and different solutions but thus far nothing has worked. That includes right clicking on the extension and selecting to add it to the toolbar.

I repeat, the extensions appear to be working though I cannot call some of them up (EverNote for example), and I need Lastpass on the toolbar for password generation and to access the vault.

Extensions ARE displaying in Chrome browser.eeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee

Attached is image of customization scree that also shows toolbar area. No addons anywhere.

I'm using a video as the background for my website, and Firefox's built-in PIP (Picture-in-Picture) icon for videos is displaying. I don't want it to be visible on my website. I tried using FFmpeg, but it did not work as it was mentioned by some people on Stack Overflow. I read that Firefox won't display this icon for videos in an iframe, but I don't want to use an iframe on my website. Is there any other solution?

Hi

I have a new mac mini with ventura. I am trying to transition from Chrome to Firefox and I have one single thing that is stopping me from doing that.

It is the color of the scrollbar thumb. Currently it is light grey on slightly lighter grey. Almost impossible for me to see with my older eyes.

What I've done so far is to set this to true in the firefox config:

toolkit.legacyUserProfileCustomizations.stylesheets

and created the userChrome.css in the correct profile folder (from firefox troubleshooting information page)

What I want is that anytime the scrollbar displays, I want the thumb to be blue so I can see it. I've not been able to find the css to do this.

Please help me with this, Chrome has become almost unusable and I need to switch to Firefox.

thanks Nick

Extensions no longer shows on Customize Toolbar tab on the latest version 111.0. I had Dark Reader and SoundFixer on the toolbar before and I can no longer add them back.

What is the code to remove that new menu Search Bookmarks in new firefox 114?

I already remove all the previous "bookmark all kind of type menu" in userchrome.css

Firefox 114 introduced hidden support for nvidia video super resolution. In about:config you can enable preference gfx.webrender.super-resolution.nvidia to make it work. However I see 0 difference on all videos on all pages. I have everything in nvidia control panel set correctly (VSR enabled and set to 4/4 quality).

Tried to find more info online and someone on reddit complained that it worked before but it stopped working with latest firefox beta (probably before final 114 release): https://www.reddit.com/r/firefox/comments/13duluz/nvidia_video_super_resolution_comes_to_firefox/

I tried using logic too - if this pref is related to webrenderer in its name maybe it is not working because I am not using webrenderer? However I checked about:support and in section graphics->composition I have "webrenderer" so it seems I am using it, but its VSR feature is not working at all.

I am in the United States. My machine is on Windows 22H2 (OS Build) 19045.3208. My version of FFox is 116.0 (64-bit).

My firefox was getting very booged down after months of usage and I complete uninstalled and reinstalled, and now Recommend by Pocket does not show up either on my Home Page, or as an option to add it.

Googling around, the two most common fixes I have seen is to fix this are:

1) Click the Personalize button in the upper right corner of the new tab page and toggle Recommended by Pocket to on, but the option does not appear there. See attached screenshot. 2) Type about:config in address bar, then browser.newtabpage.activity-stream.feeds.section.topstories, and set to true. This was already in effect. See attached screenshot.

Anything else I can try to enable it? I really like it and I miss it.

So I understand why shift right click opens the context menu, and its been useful to me when I need it, but I'd like the option to disable it for trusted websites, or just a toggle I can turn on and off when needed. Even tucked into advanced options. For reference, its an issue when I play littlewargame, a browser based RTS game. Shift is how you que commands, so target firing specific units in order or setting multiple move commands requires me to hold shift, and right click multiple times. Obviously having the context menu pop up every time is an issue. Any chance that could be made into a toggle somewhere? Does anyone know of an extension that adds that option if it isn't built in?

Thanks in advance <3

I am a backend developer (API maintainer) and I use firefox as my primarily browser at work. A feature that I would find very useful would be that firefox prettifies the "Form Data" under the "Request" tab when a request is selected under the "Network" tab in the developer tools, and with prettify I mean to display in multiple lines and highlighted properly (for a comparison example you can take the "Postman" application feature under the "raw" tab).

As of now it only displays the form data in a single horizontally scrollable line and it also has a "Raw" toggle.

Thank you and keep up the good work.

Firefox Bookmarks or Thunderbird messages folders : I'm trying to find out which folder I stored this bookmark or message in. I do a search and if I'm lucky I find a list of possible items. But the LOCATION option refers to something different from ' in which folder it can be found'. Is there a way to find this ? To find the LOCATION WITHIN THE APP ---- - WHAT FOLDER IS IT STORED IN

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?

Setting `widget.non-native-theme.enabled` to false no longer works; I still get Firefox's default styling for controls and widgets.

I use a custom GTK3 theme in my environment that I want to apply to Firefox. The above setting works in 91 ESR, and broke with the upgrade to 102 ESR.

A custom user chrome stylesheet would be too painful.

Note: You can revert page styling to defaults in View -> Page Style -> No Style.
