I am forced to switch over to the browser Brave, have been a true Firefox supporter but am unable to change the background from dark back to light, this has nothing to do with the computer desktop settings since Brave, Edge and Google Chrome all are still running with the light background. Please help since I find this unacceptable, have problems reading with the dark background. Regards, Art.

Trying to recover from a hard drive crash. Had to buy a new desktop with Windows 11 Pro (looking to be a bad move). I downloaded/updated to Firefox 126.0 (maybe also looking to be a bad move).

Have my last "working" userChrome file (it took me weeks to perfect this to my needs).

I am looking for: C:\Users\<user>\AppData\Roaming\Mozilla\Firefox\Profiles\<profile>\

but there is no "AppData" folder. And there is no existing userChrome.css file, anywhere!

Is the functionality I am looking for a thing of the past?

Is Firefox not completely supported by Windows 11?

If so, what is the last version of Firefox that will still support userChrome.css?

Nuance Dragon 15, my speech to text software, periodically opens a window and says restore privileges to the Dragon web extension for Firefox to improve performance. However, the fix it button is inactive and Firefox has never seemed to have heard of this web extension and denies all knowledge of it so the cycle continues. Has anyone else encountered this novel issue, please?

I want firefox to open a .ics file in google calendar rather than the "Use Calendar (default). I've already run the script linked here : https://support.mozilla.org/en-US/questions/1196085 to register the webcal protocol handler.

The webcal It shows up in the Settings / Genera / Applications list See attachment "Webcal.jpg.

But earlier in the applications list, there is a "Calendar" entry that only allows me to go to the "Use Calendar (default) or ask or save. See attachment Calendar.jpg

It seems like Firefox uses the Calendar entry before it gets to the webcal entry and so it always opens the default windows calendar application.

Help! How do I get firefox to use the webcal entry and not the calendar entry.

Thank you.

I must utilize a radiology based website application that works best in Firefox. I utilize 3 monitors on my system and have Firefox browser working on Monitor #3. Unfortunately Firefox opens the popup windows in Monitor #1. I cannot find a setting anywhere that would force it to open the popups on the monitor that is running the Firefox browser. I do not have this issue with Microsoft Edge, Google Chrome just this browser. I only use Firefox for this application because of this. However, I must use it 4-5 hours a day and this is extremely annoying. Is there any way to fix this issue? In today's technology and the fact that most of us use multiple monitors, I would think this browser would be up-to-date in its options and ability to handle this. Any help would be greatly appreciated.

Is it possible to configure whether Okta SSO can be configured per container as opposed to globally? I know the Microsoft SSO Integration is per container but it seems the Okta integration is all containers by default.

It requires modifying the below in about:config

network.negotiate-auth.trusted-uris

https://help.okta.com/en-us/content/topics/directory/ad-dsso-configure-browsers.htm

It would be ideal to be able to turn off this integration per container so multiple accounts could be used ie: personal, work, etc as opposed to having to go into Private Browsing.

I have Firefox running on Screen #3. The website that I use with my radiology clients opens popups and I want these to open on Screen #3 as well. However, they are opening on Screening #1. How can I get them to open on Screen #3?

Thank you.

I would like to customize my New Tab page to show only the icons (shortcuts) I specify; I think it would help if I could change the size of the icons so fewer show, but I cannot find any setting to change the way the page looks. This is a new problem since I got a new computer with Windows 11. In Windows 10 and earlier Firefox versions, I could have only a handful of shortcuts that I wanted and it did not automatically add recently visited sites (I have not selected that option in the settings). I do not want to dismiss or delete shortcuts individually, but want a permanent solution.

When visiting the "support.mozilla.org site, third-party translantion add-ons(such as "Immersive Translate") can't work. It says "can not read or change data on this site". I want to translate it on the same page rather than skipping into a new page. However, it can work on the "www.mozilla.org" site. When visiting on Chrome, there is not a problem. Is that site just privileged on Firefox ?

When I restarted my PC and opened Firefox only 1 tab Open previous windows and tabs. All the other 6 disappeared. I opened 3 additional tabs, closed Firefox, and reopened Firefox and only the one same tab was there from the previous session. Why does the feature not work properly?

I often have many tabs open (25+) I have made it so tab shrink way more then normal (I like the way chrome handles tabs where they basically just shrink infinitely. Firefox doesn't do it's even with my twerks but ohwell.)

so when i want to click on a tab with audio playing at a small size i often mute the tab instead of clicking on the tab

Where and how can i remove the mute button that appears when hovering over tabs with audio playing?

I have never found that mute button useful so removing it will not impact me

I have tried multiple Firefox Extensions for saving images instead of using the default Right-click "Image Save as" function, so reduce steps. All of the extensions have the same issue. When the filename already exists, there is no failure but instead a (1) is appended to the end of the file name. No message/prompt either to skip/cancel. It just silently appends. And (2) (3) and so on.

Is this a limitation of the Firefox WebExtensions API? Is it not possible to return a verbose failure for existing filenames?

My default search engine is Duck Duck Go. I frequently use a VPN.

I am usually in North America and want to search sites in North America. When I run a search by typing a search term in Firefox, I get results beginning in UK, and I see that a blue toggle switch has been set to UK. (See image.)

This started 2-3 weeks ago.

How do I set things so that my searches begin in North America?

I have checked "about:config" preferences and do not see anywhere that UK is specified. I don't see a region preference setting, either.

Thank you.

Hello there, Iam facing a problem with changing Firefox homepage background. I tried every solution, tutorial, oldposts etc. nothing seems to work, here is what I tried. -1- The chrome folder is in the right folder. -2- the naming of both CSS files userChrome, userContent. -3- enabled CSS files at startup -4- search for both CSS files in the browser toolbox for some reason I cannot find both CSS files, even though they are in the chrome directory. Also, I have 2 chrome folders one of them is located here. "AppData\Roaming\Mozilla\Firefox\Profiles\shaf5qn0.default-release\storage\permanent\chrome" the other one I created myself which is here "AppData\Roaming\Mozilla\Firefox\Profiles\shaf5qn0.default-release\chrome" I tried to delete the first one but I cant, I get an error that this file is being used even though I did close Firefox. What I am missing here?
