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?

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.

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to be a picture in picture button alongside settings, theatre mode, and fullscreen buttons, but on firefox this has been replaced by a clip button.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.

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

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 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.

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.

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.

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?

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!

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.

Offidocs has hijacked my Firefox browser making it impossible to read PDF files. I never added it and it does not appear in my extensions list. I've marked "always ask" in the preferences for opening PDF files but to no avail. My antivirus and Malware bytes scans are negative. How can I get rid of this?

When I use Firefox on my Mac, no matter what I have tried it keeps defaulting to the dreaded Bing Search Engine. I understand it has to do with Microsoft, but I don't use any of their products because I don't like them. In settings/search I can restore the default search engines & delete Bing, but it always reverts back to insisting on using Bing again. I have followed several threads about this issue without permanent resolution. Help??
