Firefox Support Forum

The Firefox "New tab" page shows quick-navigation buttons. At the top right of each button, the 3-dot menu has an Edit option. On the edit dialog is a link "Use a custom image", which then prompts you for a image URL.

I've tried pointing this to images in my Google Photos (a 1024x1024 .JPG), using an open-shareable link, but it doesn't work.

a) What format does the icon image have to be in? b) Are there any limitations on the URL? c) Is there a way to use a locally stored icon image?

Any guidance would be most welcome! Thanks :)

I took a video on a Google Pixel 7 mobile. It plays back on the Android cell properly. I can log into my Google Photos via my Windows 10 PC and the video will play back properly. I also downloaded the video file (MP4) to be saved directly in my Videos folder on my Windows 10 PC. When I try to play the video by clicking / opening the downloaded file on my PC I get an error message. See that message attached. It is prompting me to "download a new codec". Why? In my Firefox browser I currently have the Open H264 Video Codec by Cisco plugin enabled. Why is the Cisco plugin not sufficient? Is the Cisco plugin being updated? Does Firefox browser need to be updated? Is Is Firefox working on a fix?

How can I remove the show all tabs arrow? Also start adding an easy way to remove any changes you make in new updates. They are more annoying then helpful for quite some time already. Why would I need such feature when I use up to 5 tabs?

How do I get rid of the purple home page in Private browsing that really defeats the purpose of private browsing when everyone can see this page pop up??? I have tried setting it to private only and I still get this page upon opening. I have searched the FAQs and tried all that they suggest (except for the one that suggests not using private browsing at all). this question and problem go back to at least 2019 it seems to me it should have been FIXED by now.

In older versions (say, Firefox 85 which I have been happily using until now) you could enter the search shortcut (say, "y" for youtube), then just press enter without entering any search terms, and be brought to the main page of that search engine. In fact, search engine definition file has a specific field for that feature.

Well, I'm on FF 119 now and I find that this behaviour is broken. You MUST enter search terms now.

Is there a way to fix this pointless change, or do I have to downgrade?

Trying to download and print one of my tax documents. File type is PDF. Even in the print preview, the right margin is at least two inches, and it prints that way. I tried clicking "more" and adjusting the margin settings, but that doesn't help. I tried printing through Chrome and Edge and it prints fine. Any ideas how to get PDFs to print right on FF without having to switch over to another browser to print a document?

I see no microphone on in the address bar for Firefox. I read that it is supposed to be (standard feature?) on the left side. How do I restore or enable this feature? For good measure, would someone please send me an image (snip& sketch?) of the address bar showing what this looks like. First time posting so I don't even know if one can attach or include images in a reply.

For whatever reason the Picture-in-Picture button keeps not showing up in normal places like Prime, Netflix, Hulu, etc. I can make it come back by going to the Settings turning off the Picture-in-Picture option (Which is always still active) refreshing the settings then going back to Picture-in-Picture and turning it back on and then finally refreshing the video I was trying to use, but this is kind of a lot to have to do every time it happens and it seems to be happening more and more, so I'd like to fix the root cause instead if possible. Any ideas?

Hello, when i click the 'extensions' icon in the toolbar, it redirects me to the extensions manager site, rather than opening a little popup with a list of extensions. How do i fix this so that the popup appears again?

A couple of weeks ago, a message came from Firefox saying - do I want the facility of opening a Firefox window on starting it? I thought that would be a confirmation of my existing setting of opening Firefox with the previous tabs. But no. Firefox now opens a separate blank window in addition to the previous window with the tabs.

How can I stop the opening of an additional blank window, which I now have to delete everytime? Thank you

i've been in touch with you about an issue playing pogo games & need help please. The 1st firefox version I had worked great but changes have been made since then-I don't believe I was using enhanced protection control. The card games are not flipping correctly, some games are slow in moving pieces in a puzzle. Could someone advise me on what can be done? Thanks!

Please provide a native way to change the behaviour of Ctrl-W. I tend to switch between aZerty and qWerty keyboard layouts, as a result I sometimes hit ctrl-W when I would like to ctrl-Z some change. As a result I tend to lose some work when the tab I'm working in closes. It would be nice to be able to rebind some of the default key combinations, or at least disable them.

I found a method description that edits the omni.ja file, but also that this method is unsupported. Moreover, running ubuntu kind of rules this out as an option, as canonical has ruled that firefox is to be installed via snap, in a read-only data store.

Wishing to view my own html file in my Ubuntu Linux system I pressed the Alt key which I thought would give me a "File" menu. I could not see one. How do I get it?

I'm watching a YouTube video and taking notes simultaneously. It used to work fine, but today, possibly after update 119.0(64-bit), it's not functioning properly. I couldn't resume my video with <space> after switching back from my note using <ALT>+<TAB>.

Any solution for this? Or should I consider downgrading my FF?

I have two PCs, both running the same versions of Firefox for years. A little over a year ago, after an update, a new "Private" icon appeared in my taskbar in addition to the normal Firefox icon on one of my machines, but not the other one. This presented, and functioned as two different, independent browser applications; I could just click on the private browser icon to open the private browser without opening the "regular" Firefox. I don't know where this came from, but I like it... but it never changed on my other PC, and I can't find how to apply it; is there a setting or something I'm missing? Why did it happen automatically on one machine, but not the other?

Hi; The gear symbols that were next to the extension in the Extension Panel, are no longer there. In the recent past, clicking on the gear symbol by the extension, enabled me to pin it to the tool bar. How do I get that function back? Thank you, Nick M. mr.nick@myyahoo.com

Hello, I recently used my MacBook Air to connect with a projector for a classroom presentation. The presentation was using Google Slides. I adjusted the settings to optimize the presentation--setting the navigation and bookmarks bars to hide when in full screen.

I normally use my Firefox browser in full screen mode, but have the navigation bar and tool bar visible.

I cannot figure out how to undo what I did so that my navigation bar and toolbar are visible again when I am in full screen mode. Indeed, when I move the pointer to the top of the screen to make the navigation bar and toolbar visible, I cannot move the pointer back to the navigation bar or toolbar without it disappearing again. Essentially, I need to undo full screen mode.

Thanks, jch
