Firefox-Hilfeforum

I'm installing a Docker service set onto a new Ubuntu system, that has Firefox installed by default. One of the services is a GUI application.

However, when opening Firefox for the first time, a dialog shows up that I would like to disable (attached).

How can I disable this?

I'm running Firefox using: "/usr/bin/firefox --kiosk http://localhost"

I've already followed a lot of the suggestions in here: https://searchfox.org/mozilla-release/source/remote/shared/RecommendedPreferences.sys.mjs (and verified they are indeed set after installing my own "user.js" file), but I cannot find an about:config preference that disables what I'm still seeing.

Any help or ideas?

While I was browsing an open tab I moved my cursor over to the Bookmarks icon and the cursor automatically enlarged itself. I expect the cursor to remain at its normal size when I hover over the bookmarks icon but instead it became larger. I cannot reproduce the error unfortunately.

Hello forum participants,

since some Firefox versions the setting "browser.fixup.alternate.suffix" no longer works. I found that all "browser.fixup.alternate" entries do not work anymore. After searching the web I found an answer that the fixup.alternate options don't work when the protocol is https. So, because today nearly all Websites use https, this options are completely without function. In my case I want to add the default TLD ".de" if I do not enter the TLD. Is there any place (except source code, of course) to configure this behavior for https, too?

Many thanks in advance! Have a nice day

Marcus

When I open Firefox, the tabs from the previous session do not open despite the setting. I end up with a start page showing only a new tab page. This has been happening over the past few days and I don't know why.

Does anyone have any ideas why this is happening.

Hello, We are using a PAC-File. In the Function: FindProxyForURL(url, host) you return the Proxy. We are returning the Value:

     "PROXY proxy1:3128; proxy2:8080".

We see that Firefox often takes the fallback Proxy. The connection via the Fallback proxy is much slower than the connection via the original proxy. 

My Questions: How does Firefox recognize which Proxy is now active? Is there away to debug the Proxy Selection? Can I give a priority to a Proxy?

I don't know how you can help. I really really really hate hunting for things that were there in previous years. I do not like full screen lay over that mozilla has taken to doing, if it doesn't stop i will have to remove it. I want to see my tabs, I want mozilla to stop playing with my settings and logging me out when I am idle or on my phone. There are people with the same problem but its all techy talk and i don't understand and its playing with my time to constantly search or resign in. I don't need microsoft anything, hate it, don't use cloud, don't use chrome... so do we have an issue? one more thing... I absolutely hate with a passion of terminator any fucking ai garbage and bots. would sooner smash devices and take out a fire arm to shoot any robots. Hope that makes it clear. I have anxiety issues, so swearing is an issue, get used to it especially if artifical nonsence is involved. I try very hard not to swear at people. Ai is a different matter. I have norton antivirus.

As I am a corporate website administrator and I use an ultra-wide monitor with a resolution of 3840x1600 pixels, I need to be able to run firefox with window size of full HD to verify the compatibility of the site for common displays.

How can I ensure that the Firefox window always starts at this size?

In the case of Chrome, you just add the parameter -window-size=1920,1080

Unfortunately, this solution does not work here (so it worked in older versions).

I found some plugins that promised this, but none worked correctly.

I find the option to set a default size to be very basic and essential and prevents me from switching from Chrome to Firefox.

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

Does anyone know how to do this?

To give a better description:

1) I partially type a website I've visited into the address bar and the history recommendations show up. For example, I type "yout", the address bar shows "youtube.com"

2) I middle mouse click on the "youtube.com" recommendation to open it in a new tab.

3) Firefox is instantly swapping me to that tab and ignoring the behavior I changed for tabs.

I have "browser.tabs.loadBookmarksInBackground" set to true. When I use middle mouse on a link on a website, the behavior works as intended. The link opens in a separate tab but keeps me in the same tab from which I clicked.

i made a custom firefox colour setup for my desktop machine, and it doesn't have any option to save it- because of this, on my laptop which is synchronized to my desktop's firefox settings, it is not showing up at all and if i go to firefox colour it isn't there for me to add. so how do i DO this???

i do not want to maker my custom setup public so it is not available to all, it is my own setup using some of my own artwork which i do NOT want made public on the internet.

there MUST be a way to save it however and let my laptop's firefox also display it,m yes???

and on that topic, why isn't it just automatically synchronizing when everything else does?

So when I installed an update today all of my extensions and add ons were removed and I have a folder on my desktop that apparently has all their data is there any way to restore that data? Or is it just lost in the update?

Hello, I use Firefox as my only browser and I use the shortcuts because they're really helpful. But every time that I lunch Firefox all the pages in the shortcuts "call" their websites, I see it from pihole and all the requests are made every first lunch of Firefox. Probably it's something related to the cache and to give better perfomances in case I wanna select one of those shortcuts, but I don't want that all of them make a "call" to their respective websites. I think it's something related to privacy and freedom about what I want to do with mt browser. Is there an option to block those connections? In case there isn't an option is possible to implement it? Thank you so much
