Firefox-Hilfeforum

Frequently when I update Firefox something stops working the way I want it to. So after the last update I disabled updates. That was a while ago (version 89) and my browser was getting pretty stale. So I backed everything up, reenabled updates, and now I have version 104.

And, of course, something is broken now. The context menus when I right click are not functioning as before. The userChrome.css is still there in the chrome folder in my profile and has the same contents. The option toolkit.legacyUserProfileCustomizations.stylesheets is set to true. But it doesn't work anymore. I added a line to change the color of the tab toolbar and that worked. So userChrome.css is being read and acted upon. But the other command (I whittled it down to just one additional command for testing) is ignored.

Here is what my userChrome.css looks like right now:

@namespace url("http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul");

1. context-openlinkintab { display:none!important; }
2. TabsToolbar{ background-color: #CCCCCC !important }

But the "Open Link in New Tab" still appears in the context menu when I right click a link. It didn't do this before the upgrade to 104. Did something break in between version 89 and 104 or is it some other oddity?

Any ideas?

I have recently updated to Firefox 106 on two Arch Linux systems. One of them has Firefox View enabled and working by default, another does not. I looked around and tried some options in about:config to enable it, however it did not work and I reverted the changes. I would like to enable Firefox View on this browser as well, and I would like to know how to enable it.

Several times now, I had my bars switch out on me.

It was: MENU BAR TOOL BAR BOOKMARK BAR ADDRESS BAR

It is now: menu bar address bar tool bar bookmark bar

I DESPISE THIS SETTING!!!!!!!!!!!!!! Why does it continuously change each update? Can't you just leave my dang bars the way they were set up for more than 15 years??????????

I have severe Asperger's, you're BADLY screwing my days up this way. It was pure horror to get them back, EACH TIME, as you (Firefox) figured to change it. DON'T MESS WITH MY BLOODY SETTINGS!!!!!!!!!! I can't work like this!!!!!!!!!!!!!

How do I fix it this time?

For crying out loud. Stop screwing with the settings, and gimme a hand here, please. How many times do I need to ask this?

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.

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

I enjoy this handy addon, but it's got a couple bugs

Default Bookmark Folder

It's a recommended addon, but It seems that it's no longer being supported. Version is two years old, and issues reported on github are not responded to.

I wonder if anyone could recommend another addon with the same features.

Hello

Using the video player for streaming on http://www.rumble.com running Firefox version: 116.0.3 - shows up letterbox black bars on the left and right sides of the image via my main, default profile that cannot be cropped with zooming.

Using a brand new, clean profile with the same 100% default zoom setting, the same Fonts settings, the option for 'Allow pages to choose their own fonts, instead of your selections above' is enabled on both profiles, the uBlock Origin add-on is also enabled on both profiles as well, (but even with the uBlock Origin add-on disabled on my main, default profile the letterbox black bars for the video player are still present).

I've tried comparing all the settings on my main, default profile to my brand new, clean profile but from what I can see everything is just about identical.

Bellow are screenshots of the video player in action on the rumble website of my main, default profile vs my brand new, clean profile with the zoom level set at: 180%

The only aspect that I can recall which is different between the 2 profiles is that a little while ago on my main, default profile I changed the scrollbar in "about:config" to the Android version because I like how thin the Android version of the scrollbar is, but apart from that I can't remember anything else I changed.

I don't really want to migrate over to the brand new, clean profile because I have my main, default profile configured the way I like it, so if anybody has any advice on how I can get rid of the letterbox black bars that would be appreciated.

Note - this only happens with the rumble website, doesn't happen with the YouTube website or any other video streaming platform.

For the last several FF versions, although I choose a light theme, the pull downs/menus always wind up dark with white text. It also shows up when I am editing options in FF itself. How do I stop this? I want a light background with black/dark text.

I used to be able to send tabs between my devices, say when I go from my home computer to my laptop. This option seems to have gone missing, like I don't even see the option when I right click on a tab. What happened to this option? Did I somehow disable it? Can it be restored?

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

With the new v85 of Firefox... for Microsoft Print to PDF...

the defaults for print headers & footers has changed and is no longer available to edit or even view. It seems as though my settings remain in place for other printing options like my physical printer but even there the options are not editable or viewable.

There used to be a "page setup" option but I have not be able to find this anywhere anymore.

• Bulleted list itemhttps://support.mozilla.org/en-US/kb/how-print-web-pages-firefox#w_changing-the-page-setup

I'm assuming that it has to do with the bug fix for pdf printing but doesn't seem that it should be an intended outcome of the fix.

Any work arounds anyone knows about or has found?

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.

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.

I will be to-the-point: Firefox 109.0 has forced the "extensions" icon (a puzzle piece) on my Bookmarks toolbar.

(1) I do not wish for it to appear there (2) I am not given the possibility to remove it from the "Customise toolbar" screen

Please assist.

I'm using freshly-downloaded Firefox version 102.2 on a brand new laptop (Windows 11 Pro version 21H2), and every single extension is showing a "Installation aborted because the add-on appears to be corrupt" message when I try to install. I have tried checking for updates, quitting and reopening firefox, restarting my computer, refreshing firefox, uninstalling and reinstalling firefox, as well as any and all combinations of those. I've scoured these message boards and nothing is working for me. Please help!

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 )

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!

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 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.
