Форум поддержки Firefox

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 would like to ban the Quora website altogether but especially from answering searches I make. What I have found so far does not work. Any suggestions? If I can do that I might even do that to another website that I see no value in. Thank you.

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

Hello,

Is it possible to disable the prompt to allow a website to store data in persistent storage?

Firefox 122 on Windows

Screenshot attached.

Thanks!

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?

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

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?

Refresh Screen nags are beginning to take over my web-surfing experience. On InstaCart I get hundreds of Screen Refresh nags -- one right after the other. Blowing Screen Refresh nags out of the water won't hurt my feelings... InstaCart will generate thousands of Refresh Screen nags -- until I nuke it.

I am trying to install Adobe Flash player in Firefox 84.0 (the last version support Flash player) when running in a docker container (Ubuntu 22.04.3 LTS). I had tried to run Firefox in my real machine (Linux 6.1.0-17-amd64 Debian 12) and it worked well. I just copy the file "libflashplayer.so" to the path "~/.mozilla/plugins". But when Firefox is running in a container, I do the same but it can't found Flash player plugin. No matter where I place the libflashplayer.so, like "~/.mozilla/plugins" or "/usr/lib/firefox/firefox", it don't work, I can't find Flash player in "about:plugins" or "about:addons". I start Firefox from a terminal and there is no error log. I have no idea why it can detect flash player plugin while running in a real system but don't work when running in a container. Thanks.

I use Firefox on Raspberry pi os. I have a lot of help files saved in mht format. How can I open these files in Firefox? Chrome supports such files without additional configuration, but I would not like to use this browser on Raspbian, since it consumes much more resources than Firefox. It is undesirable to use a different format.

On new window (`Ctrl-N`) I want the focus to be on the url bar, not the homepage. I believe this is the default behavior if no homepage is set, but I want to set this behavior independent of the homepage setting.

Is there a setting for this?

Same as below, but solution did not work for me.
