How can I completely remove the tab bar and regain 3/4 of an inch of screen space. It would be nice if Mozilla would just have a on/off button for it. I've tried creating a folder called Chrome within my Firefox Profile folder. I then created a text file within that folder and named it userChrome.css. I put this string in the text file #tabbrowser-tabs { visibility: collapse !important; } This did not work, does anyone know the best method for getting rid of the annoying tab bar?

Thank you

I've just switched to firefox from brave, and theres no button on twitch to enable picture in picture. Using the keyboard shortcut (cmd+option+shift+]) works, but I'd much rather click something on the screen. On brave there used to be a picture in picture button alongside settings, theatre mode, and fullscreen buttons, but on firefox this has been replaced by a clip button. There's no option for it if I right click (this works on youtube), and no option in the address bar for either twitch or youtube. I've tried disabling all my extensions and lowering protections but nothing seems to work.

Good morning. My Firefox version is 117.0 and I am running Windows 11 Home. Currently except for Ublock all my other addon icons are grayed out on my toolbar. My webadvisor, Capital One, just gray. This is a new behavior and I'm not sure what happened. I am also curious why just Ublock is colored in. Thanks in advance for any help you can give.

You know how you can type a URL and then Ctr+Enter and FF autopopulates the .com? Well years ago "Shift+Enter" autopopulated ".net" and "Ctrl+Shift+Enter" autopopulated ".org".

I really liked that feature. I know a lot of people don't, or don't see its point; that's not important.

About three years ago, I added UserChrome.js and enable-UserChrome.js , which acomplished the two autopuopulating tasks quite nicely.

Until about four weeks ago. I don't know if an FF update stopped reading those two .js files, or if there's a conflict somewhere else, or what. I don't know where to begin - other than posting here for help.

Thanks in advance!

• UserChrome.js is in the subdirectory: C:\Users\[ME]\AppData\Roaming\Mozilla\Firefox\Profiles\gaydtewj.default-release-1
• enable-UserChrome.js is in C:\Program Files\Internet Shenanigans\Mozilla Firefox\defaults\pref (firefox.exe is in C:\Program Files\Internet Shenanigans\Mozilla Firefox )

Embedded videos missing in Firefox but show up in Microsoft Edge. How to fix it?

I was set up, in myuserchrome.css, to hide my pinned tabs on the tab bar, allowing them to still be available in the "List all tabs" menu, see first image

.tabbrowser-tab[pinned="true"] { display: none !important;}

All of a sudden, it reverted back

That first image, with the hidden tabs, is actually from Librewolf, with has the identical setting.

Hi All,

I would like to change the url border color when it has the focus to blue.

The code below works, except when you press Escape.

After hitting Escape, the urlbar still has the focus but its border changes back to gray. It should remain blue.

I would also like to remove the box-shadow after pressing Escape, when the urlbar is not expanded (to mimic the behavior of FF 88).

The url and search input fields also do the same goofy thing Windows 10 does - the cursor stops blinking after 5 blinks and remains frozen. Any way to remove that behavior and keep the cursor blinking? If not, no big deal, the other stuff above is more important.

Any code suggestions to get that behavior are welcome!

/* set the initial borders of the urlbar and search bar to gray */
#urlbar > #urlbar-background, #urlbar[breakout][breakout-extend] > #urlbar-background, #searchbar { border: 1px solid #a1a6b5 !important; outline: none !important; border-radius: 0px !important; }

/* set urlbar border to blue when focused */
#urlbar[breakout][breakout-extend] #urlbar-background {
   border-color: #0078d7 !important;
}

I installed Firefox-ESR on my Raspberry PI and noticed that I cannot play Udemy videos. After some research I found that the Widevine plugin is missing and the OpenH264 Video Codec is also not installed. Following the instructions from similar issues didn't solve the problem. I ticked off and on the "Play DRM-controlled content" button but this only brings the widevine plugin for a moment and after that it disappears. In the network tab I see no activity when click on this button, i.e. Firefox does not send requests.

Additionally the OpenH264 Video Codec is not installed and never installs.

Any ideas how to solve this?

I have read through all 3 of the following posts linked below on this issue, and cant make it out.

I am trying to move the find bar to the top of firefox. Tried the really long codes suggested, and the short ones. Yes, I enabled "true" in the config settings. Added the chrome folder and text file, I think in the right section. Restarted firefox lots of times upon each code I tried, still not working.

Any ideas? thanks!

Unfortunately, I downloaded “SaveFrom.net Helper” without reviewing it.

Since downloading it I have been receiving a alerts from “McAfee WebAdvisor” about “dangerous pages blocked”.

I was able to remove the “SaveFrom.net Helper” add on in Firefox, but am unable to remove the “Savefrom.net Helper” bookmark tab which has high jacked my normal Firefox Bookmarks.

I can no longer easily see my Firefox Bookmarks and have to keep opening the Firefox Application Menu, then select Bookmarks, then select Manage Bookmarks in order to see my bookmarks.

Can you please advise how I can safely remove the “SaveFrom.net Helper” bookmark tab which has high jacked my Firefox Bookmarks.

SLES 15.5 QU2 in Mozilla Firefox 115.8.0esr was not supporting window.close() even i added user_pref("dom.allow_scripts_to_close_windows", true); in user.js and prefs.js

When I tap the middle mouse wheel to enable auto-scrolling (with no additional inputs like clicking, scrolling, or keyboard inputs), on release of the middle mouse wheel, auto-scroll disappears. I can only use auto-scroll while holding down the middle mouse wheel.

I've reached out to other's and this seems to not be the intended/default behavior. I've confirmed middle-mouse wheel scroll (where it's a tap / toggle) works on Chrome as well as other applications like Spotify.

I would like to have it as a toggle. What can I do?

New addons on Firefox become blank on restarting the browser.

They return when I manually disable and enable them once.

How to fix this? Doesn't happen to older addons.

This again!

This was resolved about a year ago; now the problem is back, as of updating to Firefox 113.0.1 this evening.

Initially post-update the close tab button was in a weird, random place on the tab bar. I have adjusted the margins to put the button back where it's supposed to be!

I changed :

.tabbrowser-tab .tab-close-button {
  opacity: 0;
  margin-left: -4.5px !important;
  margin-right: 2px !important;
}

to:

.tabbrowser-tab .tab-close-button {
  opacity: 0;
  margin-left: -4.5px !important;
  margin-right: 35px !important;
}

to move the button back onto the left. That may seem like a drastic change but that's the lowest value I could find which produced the result I want.

However, it's not quite the result I want! As of updating to 113.0.1, the tab title itself now disappears altogether on hover.

I have tried to correct this in CSS using the .tab-text and .tab-label attributes, but without any luck so far.

Can anybody help me with this, before I'm forced to downgrade to Firefox 112?

Better yet... how about we just make this an option in Settings, as it should be?!

Hello. I recently moved from windows to Linux Mint, and noticed the behavior of the Picture in Picture window is different when resizing. On windows, the aspect ratio is kept. while on Linux, it is free form, making these black bars around the video, so I have to resize it very carefully to not show any black bars.

How can I make the PiP on Linux behave like on Windows? That means resizing keeping the aspect ratio.

Attached are the comparisons between Windows and Linux Mint.

Thank you very much!

I went into setting and made sure spellcheck is enabled and it is, but there are no other options there. I did exactly what it said on your help article and right clicked in the text box on multiple different web pages and there is NO OPTION. It should not be this complicated.

Does anyone out there know of a replacement for the Tab Groups replacement app? I have not updated Firefox past the v.55 only because I don't think it would work w/ any newer versions. I have found this to be the very best app I have ever used as I need to do a lot of research online and need something that will show all the windows and tabs on one page so I can easily go back and forth to a particular group quickly. Without this, I would have to spend hours finding the info and would only have one window in which to work. Ideally, a replacement would be able to use all the window/tab info I now have. Is there some way I could use this in some sort of legacy mode? I have several legacy apps, but can't readily recall how to do so. I think I tried this w/ the Tab Groups app and it didn't work, but am not certain. Suggestions much appreciated! Thanks, Wolfgang

Until recently, I resisted allowing updates for Firefox because of the announcements of changes to prevent access to some technical kinds of website which I use. These include the public websites of the Paris Observatory which include useul informational ftp pages with important text, data and software files.

  I did recently allow a Firefox update, and now I find that I am cut off from access to these ftp pages. 
  How can I re-enable access to ftp? If it can't be done in the new version of Firefox, how can I return to an older Firefox version that does allow such access?
