Firefox Support Forum

Hello, so I am not very experienced and recently discovered how to customize Fire Fox using the userChrome.css file. I went through all of the steps that are required in order to do this. I set up a folder called chrome in the directory /Users/my name/Library/Application Support/Firefox/Profiles/x1oheo82.default-release To test if it works I wrote this into the userChrome.css file: @namespace url("http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul"); /* set default namespace to XUL */

1. TabsToolbar{ background-color: #FF0000 !important }

and set toolkit.legacyUserProfileCustomizations.stylesheets to true After restarting Fire Fox I saw that nothing changed. I double checked if there was a hidden file extension or if I might be in the wrong directory. I tried different code to see if there was some error in the code but nothing changed. I watched countless tutorials on You Tube and tried to find answers on google but nothing that I did seemed to help. I don't know if it has something to do with the operating system I am running or if it is a limitation of my computer hardware (I am running Fire Fox on an m1 mac).

I am able to install Firefox, but as soon as I try to open it, after a second a window pops up for probably about 1 frame, and is barely visible. I have tried all of the things I could, but am not able to fix this.

macOS. Firefox is running. I enter: open -a Firefox --args -private-window "https://apple.com" (in Terminal or Automator) which I believe should open apple.com in a new private window, but although the focus change to the already open Firefox window, a new private window does not open. It does work (apple.com opens in a new private window) if Firefox is not already running, but I thought the -private-window argument is supposed to open a new private window whether Firefox is already running or not. What have I got wrong?

I began having trouble w/Firefox browser yesterday evening. I submitted details several times. Completed lengthy Win 10 update. Today, Firefox icon in Task Bar is requiring Google log-in? Have no idea why or how to fix.

As you can see in the title, Firefox crashes immediately opening, though sometimes it works for a few seconds. I have figured out that it works when I create a windows profile without any association to my Microsoft account, it does actually work, but as soon as I add the Microsoft account to the profile, it crashes. This also happens with Opera GX, but not Chrome.

I'm unable to check out when I'm signed into my accounts at target & clinique.com.Target say my checkout page is slowing down firefox-click stop -I click stop&I cannot check out.

This has just started happening since I was forced to reinstall windows after a critical failure with my MBR for some reason.

I have all the settings where they should be to prevent websites from continually being logged out when I close Firefox....but each and every time I start up a browser window again...I am asked to sign in again no matter what. I am not so concerned about a majority of them, but I had it so that when my Firefox browser first opened, it went directly to the Google home page and already had me signed into my Google/Gmail account. But now...nope. I have to sign in every. Single. Time!

Right now, I have all my settings marked as I have seen in numerous other posts:

I have made sure that there ARE checks in the boxes for:

• Remember browsing and download history
• Remember search and form history
• Clear history when Firefox closes

And inside the History settings, only the cache is marked to clear every time Firefox closes.

I have made sure that there are NOT checks in the boxes for:

Delete cookies and site data when Firefox is closed Always use private browsing mode

And inside the History settings, there is no box checked for:

• Browsing & download history
• Active logins
• Form & search history
• cookies
• site settings
• Offline website data

None of the topic discussions about this or any combination of settings have worked for me thus far, and it getting to be quite maddening at this point. I need some help here so that when I open Firefox, I am not constantly logged out of

When I load Amazon.com, the webpage is a lot of text and random pictures. Amazon's layout is broken. I loaded the same page in Chrome and Safari without a problem. I reinstalled Firefox 99.0.1 without any improvement. Please fix.

Greetings... I would like to increase the font size in right click menu box in FF 89.0 (64-bit) (see attached png)

I found a similar 2018 query here at: https://support.mozilla.org/en-US/questions/1241117#answer-1174375

and based on that exchange I added the following to userChrome.css file

/* FONT SIZE IN RIGHT CLICK MENU BOXES 5/1/22 */

1. mainPopupSet menuitem,
2. mainPopupSet menu { font-size: 16pt !important; }

/* */

I closed and reopened FF. This change has no effect on the menu font no matter what font-size value I enter. Have I done something wrong?

I can no longer choose where downloads go. I have tried "always ask" but I am getting no where. One post said open the three bars on the right an look for option. NO luck.

Thank you.

Hello I have problem on my fedora workstation. When i click right button on the lowest bookmark on my list, the menu is hiding outside the screen and i can't see options.

I AM CSCTRANSPORT.IN LAST FEW DAYS ITS NOT WORKING WITH MOZILLA FIRST PAGE MAY OPEN AND REDIRECT TO ITS SOURCE PAGE THEN IT WILL SHOWS SORRY PLEASE TRY AGAIN MESSAGE

I have noticed in a couple of websites, a link or text box does not appear in Firefox, but does in Chrome (unfortunately, I don't remember which site that was). Also I have tried to open my Citibank account (Citibank.com.au) but it comes up with an error and wont open, yet it does with Chrome. I would rather not use Chrome, but I may not have a choice if this problem is not addressed.

I got help with this from your group some weeks ago, but I had to reinstall my Ubuntu OS (linux v.20.04.4 -- using firefox) recently and can't recall the answer.

When I view a WikiSpecies list of file names (e. g., see https://species.wikimedia.org/wiki/Pentatominae), the instances which have been installed but never used should be in a different (reddish) color. I am attaching an image of a page containing a file named "Abadia" (first one on the left, just under "A") which is unused. I also am attaching an empty "Creating Abadia" which is the result of clicking on "Abadia".

Please tell me how to change the image of an unused, empty file. I recall that there were two different choices SOMEWHERE in the system, "Always" and "Never" I think: One of them forces a system-level color pattern which includes reddish unused items; the other allows the used to program arbitrary displays such as the above (typical example from the dconf editor is 'bg_color: #f0f1f2; selected_bg_color: #023C88', but this editor does not change the appearance of a file instance.
