When the system theme (light/dark) is switched globally, Firefox recognizes this and also switches its theme automatically (if configured appropriately). This should also retheme addons opened in the sidebar (Tab Stash or Sidebery for instance), and it does so under certain conditions, namely if either a) no sidebar was opened when starting Firefox and the addon sidebar window is opened directly, or b) the sidebar was opened with start of Firefox. Unfortunately, no retheming of the addon window occurs when some other Firefox sidebar (such as bookmarks or history) was opened after Firefox start and before system theme switch. In that case, the addon window (which is opened as the system theme is switched) does not retheme. This can be mitigated by either restarting Firefox or by opening a Firefox sidebar such as bookmarks or history, and switching back to the addon window.

So to reproduce this behaviour:

1. Open Firefox and some sidebar addon directly (such as Tab Stash in my case, with Ctrl-Alt-S)
2. Switch system theme globally (I do this with Night Theme Switcher in GNOME)
3. Observe that Firefox correctly redraws the addon window
4. Open bookmarks (Ctrl-B) or history (Ctrl-H)
5. Reopen the addon window
6. Switch system theme globally again
7. Observe that Firefox does not correctly redraw the addon window
8. Open bookmarks (Ctrl-B) or history (Ctrl-H) again
9. Reopen the addon window
10. Observe that Firefox redrew the addon window

This has already been reported to the addon developer, who stated that it might be a bug in Firefox, since his addon only tells Firefox which colors to use in which mode.

System details:

• OS Version: Linux 6.7.4-arch1-1
• Browser Version: Firefox 122.0.1
• Desktop environment: GNOME

I've tried a few addons that download website images but the website I go to has thumbnails that are linked to larger jpg's and addons I've used won't download the linked jpg's. I used "Download all images" addon which has a "Deep Search Option" and filters for downloading linked images but I can't get it to work. I couldn't figure out how to use the filters. I read about another addon called "download-links" that can search linked images and I might give it a try. Any suggestions? Has anyone tried "Download all images" addon?

Roboform does not load. I have reinstalled it and the toolbar does not load or does the roboform small icon.

Hello, so I have been putting my custom links onto the 'top sites' start page in Firefox, by editing the icons and putting the URL, etc. It is a great 'speed dial' type feature I love. One thing has me tearing my hair out after trying all ways to try and fix this to appear to my liking, is the 'custom icon' from the website not showing in the sites I want to 'speed dial' Facebook and YT show up fine, but random sites I want on the page don't do this. I don't care why this is anymore, please don't give lengthily fixes. It's just silly you need a working URL with an icon at the end of it to display this properly. It did make me very mad, can you tell, even madder when I saw it done as it should be in OPERA browser, on their 'top sites', or 'speed dial' customizable home page they have the sensible option there to pick your own icon, you can put in a folder on your desktop if you like, no working URL needed! start a collection of what icons you want to see on your own start page. Can you please implement this 'common sense' modification as soon as possible, it will take only minutes of code writing i'm sure. I do not want to, but I will go to Opera as my main browser for this common sense functionality, good luck and thank you.

In the browser settings I use a color preference that replaces white with black, this works with pages where Dark Reader is not available. These settings are needed so that when surfing the web at night with the dark mode on, my eyes don't hurt from contrasting bright white elements with dark-colored pages. For example, it works on single image pages - in situations where except for the image the rest of the page is colored solid white; It also works for some add-ons - on settings pages and pop-ups.

I'm interested in being able to automate toggling on/off the «Use system colors» checkbox, which is in the browser «Color» settings. It would be great to somehow synchronize the activation of night mode in Dark Reader with disabling checkbox responsible for using system colors. Or, for example, make it so that when the «Website appearance» setting is set to «Automatic», the checkbox is switched accordingly together with it - being disabled when the appearance is dark and enabled when it is light.

Hello, Under about:preferences I went to applications. Under mailto there were references to Yahoo and Gmail which I deleted. Now then when I click on an email address link on a webpage the mailto menu pops up like it always has but Yahoo and Gmail are no longer listed as email options. How do I get those links back? Firefox is listed as the default option but because there are no links to webmail services there is no way to send an email from that menu. Sincerely, MKH

Should I use DuckDuckGo Privacy Essentials with Mozilla/Firefox? Would all of the Firefox features work the same or would DuckDuckgo replace Firefox features? If both worked together it would seem to be the best option. I would greatly appreciate some input on this.

Is there a setting to avoid firefox swapping to new tabs, when ctrl-clicking search results in address bar?

Sometimes I want to search on multiple things through the address bar, but usually I search on google instead because every time I ctrl-click to open the searches, firefox automatically switches to that tab which means I have to swap back to the other tab, every time I open a new tab through the address bar.

It's only a problem in the search bar. Bookmarks and links on webpages open in new tabs, without swapping to those tabs.

Hello there,

I like Firefox to ask me what to do each time with PDF documents, so I've set the action for PDF to "Always Ask". However, I've noticed that when I load a page with a PDF document embedded inline, and I select "Open with Firefox" on the dialog box, the document always opens in a new tab.

In other words: there are certain PDF documents that get displayed inline when the action for PDF is "Open in Firefox"; but those same documents get opened in new tabs when set to "Always Ask".

Is possible for Firefox to display PDFs inline while asking me what to do each time?

Thanks in advance!

Hello

As the title says: How to make firefox open ANY AND ALL Torrent or Magnet, FROM ANY SITE, without asking for confirmation ?

I Use Mac OS Firefox as my primary client for Gmail, and I always compose emails in a pop-out window. Ever since Firefox 124, these pop-out windows include the tool bar and bookmarks bar, eating up a bunch of space. I do want those bars displayed on my main firefox window, I don't want them displayed on the pop-up Gmail compose windows. Is there anyway to get Firefox revert back to this old behavior?

Updated to Firefox 124.0.1 on March 28 (from 123.0.1, which was installed on March 12). This update also installed the Keeper password manager addon.

This is a work PC so it's locked down by IT admin, including extensions on FF. I have no access to about:addons ("Blocked Page - Your organisation has blocked access to this page or web site") and it's impossible to install Xpis.

However, extracting info from extension.json shows that Keeper® Password Manager & Digital Vault Version: 16.8.1 was installed at the time the update to FF 124.0.1 happened. See images.

How can this happen? What can be done to remove Keeper, given that I don't have access to about:addons?

Possibly relevant: I do have some extensions that I had installed before Firefox extension access and install was locked down by Admin (lock down of FF was done remotely through some kind of policy), including LastPass.

Hello,

I'm using a PC with windows 11 and my Firefox is up-to-date 124.0.1 (64 bits).

1- It's been several years since a "full screen <=> rest of page" transition was implemented on youtube (using the scroll wheel for example). Is there a way to completely hide YouTube's vertical scrollbar in full screen mode?

I've checked with Opera and Edge browsers and their behaviors are normal in my mind, as the bar is simply hidden in full-screen mode, no matter where I move the cursor. https://ibb.co/nkJzb8S

On Firefox, it is hidden but only if you don't move the mouse or hold the cursor over the scroll bar. https://ibb.co/VW3JTzp Is this an expected behavior in Firefox?

Otherwise, I've tried a couple of "hide scrollbar" style add-ons, but nothing worked, at least for this particular vertical bar, in full screen mode. I also tried the Troubleshoot mode, and to delete the internet cache with no more success. Here's how it looks in pictures (moving ones :) ) to make it clearer https://www.youtube.com/watch?v=UrJa60LHEws

2- Another question please, why are add-ons disabled on mozilla.org pages, and is there a way to enable some of them on there ?

Thanks for your attention and any help you can provide. Damien F.

Hi,

I am just wondering can you help me with my problem. I am currently doing a ICDL Essentials course with E-College and I am having a problem with ICDL connect as part of the course. It's something about a PSI In-application plugin if you know what I mean by that ??? it won't accept this plugin for some reason, can you help me with this problem please thanks.

Thanking you, Kind Regards, Siobhan Mc Brearty.

Previously I've been able to select search suggestions using the keyboard when typing into a search bar. As of a few days ago this no longer works on some sites like YouTube, but does work on others like Google. The issue is not to do with num lock or scroll lock, and my browser is up to date (124.0.1 Ubuntu Snap version).
