Firefox Community Forum

Hi, I am using Firefox on Mac Os Tahoe and IOS 18.7 and 26.2 (2 iPads). I have set up synching of my open tabs, but this works only from MacOs to the iPads, not the other way round. When closing MacOs Firefox tabs on the iPads this does not synch back to the Mac. I am missing something?

I’m seeing a layout and font spacing issue in Firefox that doesn’t appear in Chrome or Edge. The page loads, but some elements shift after render and text spacing looks off.

I’ve tested in a private window, disabled extensions, and cleared cache, so it doesn’t seem profile-related. Any suggestions on what Firefox settings or DevTools checks might help?

Page where the issue is reproducible: dbrosmenu.com Thanks.

thank you for your time & expertise:) Can you please help me understand what would happen if firefox stops supporting windows 7 users. Will i still be able to use the browser - just with less security? I will probably have to give up using a computer if I cant continue with Windows 7 so I'd even be prepared to pay an annual fee to keep the support going. Look forward to hearing from you, thanks Julie

Hi,

Unable to copy text from Firefox browser. This includes copying from the body of a webpage, webpage URL in the address bar and "about:support" Troubleshooting information.

Behaviour: When copying the selected text, nothing is pasted. When cutting the text, (text is removed where possible ie address bar, or text fields), nothing is pasted.

I am able to paste from a different program into Firefox ie from Notepad to Firefox.

Attempted fix: I have tried refreshing Firefox. Problem persists.

Please assist.

I searched how to disable any random new AI features Firefox was about to cram into the browser.

I was served this support page that says I can "Block new and current AI features (single switch)"

Simply, the described feature to disable AI features isn't in the settings. I've look and tried searching for "Block AI enhancements" & "AI controls" but no luck.

Please tell me they haven't given the writing of support pages to some shitty LLM.

Before installing recent update (115.32.0 esr) I had no problems to print to Brother MFC-7360 printer or Save to PDF; now, neither of these selections will perform their function. I have tested the printer and can print a Windows Printer Test Page ; I can also print using Windows Reader. Please advise what I can do to correct this issue with the latest version of FireFox 115.32.0 esr. I even tried the "clear saved print settings" in the "more trouble shooting information" ; "printer"; "troubleshooting"; I don't think that did anything.

Thank you.

They play for a couple of seconds, then the panel they are playing in goes black. They used to work a month or two ago. Videos play fine in YouTube. They also play fine in apps like VideoPlayer and VLC. They play fine in Chromium based browsers Opera, Brave and Vivaldi. My graphics card requires switching acceleration off. I can’t find a switch for that in Firefox.

Problem Videos start playing, then after a few seconds the video panel turns black. Audio may continue. Refreshing does not help.

Environment

   OS: Fedora Linux 43
   Firefox 147.0.1 (also tested Firefox Flatpak)
   Display server: Wayland and X11 (both tested)
   Hardware acceleration: on and off (tested)
   Media Source Extensions: enabled (disabling MSE triggers an “unsupported device” error)

What works

   BBC News videos play correctly in Chromium-based browsers (Brave, Vivaldi)
   Videos play correctly in mpv/VLC
   Other video sites (e.g., YouTube) play correctly in Firefox

What I’ve tried in Firefox

   Disabling hardware acceleration
   Disabling VA-API
   Disabling WebRender
   Disabling RDD sandbox
   Running Firefox under X11
   Using the Firefox Flatpak build

None of these measures help. This suggests the issue is related to Firefox’s interaction with BBC’s player on Linux. Has anyone else seen this, or is there a known workaround?

I am unable to sign in to my yahoo mail account. It gives me a fault that "something went wrong, please try another device". I can use brave as my browser and sign in with no problem but not with firefox. Any idea why?

NB - For the past half a year I have to sometimes right click to interact with them, anyway

Effectively, I will interact with the extension at the most basic, normal level on something that has interactive elements like a dropdown menu, or basic options.

I will click / right click on the icon and the highlight will appear, then that's it ... the browser then crashes and does not recover. :(

What's worse is that I have to Force Quit and when I restart there is no crash report to send to Moz.

I am just wondering if other Linux users have experienced similar issues.

The attached image is taken at the moment before the 'Force Quit' dialogue opens up in Debian 12 Gnome (Wayland) ...

I have Hardware Acceleration on.

I am about to start testing with it off, but I work from the browser, and do not want performance compromises. So that is (at best) a work-around, and certainly is not a fix.

I'm on version 147.0.2 (64-bit) which would appear to be from the Mozilla Firefox Debian Package mozilla-deb - 1.0 install/repo/whatever ... and the PC specs are: Processor: Intel(R) Core(TM) i7-10850H CPU @ 2.70GHz Memory: 32705MB (11893MB used) Resolution: 7680x2358 pixels OpenGL Renderer: Quadro RTX 3000/PCIe/SSE2

These are my media. prefs ... but ... I doubt that it is relevant: media.ffmpeg.allow-openh264 true media.ffmpeg.customized-buffer-allocation true media.ffmpeg.disable-software-fallback false media.ffmpeg.enabled true media.ffmpeg.encoder.cpu-used 7 media.ffmpeg.encoder.enabled true media.ffmpeg.encoder.quantizer-max 35 media.ffmpeg.encoder.quantizer-min 10 media.ffmpeg.vaapi.force-surface-zero-copy 2

so i had a bunch of bookmarks saved, and when i logged in today they are gone, replaced with a message For quick access, place your bookmarks here on the bookmarks toolbar. manage bookmarks (link)

so when I use the link I cant restore bookmarks, cant seem to save new bookmarks, and the FAQ section isnt helping, some of the stps they talk about are greyed out in my version, so I cant click on them etc.

Is this a windows 10 issue? Am I the only one having this problem?

Error message: the bookmarks and history system will no be functional because one of Firefox's files is in use by another application. Some security software can cause this problem.

I tried following the directions in "learn more" but to no avail. Please help this senior citizen get his bookmarks back! Thank you.

I manually added shortcuts to my home screen, but everytime I open the browser, the system automatically has added shortcuts I don't want. Also, when I delete these unwanted shortcuts, another unwanted one appears.

how can I stop this from happening?

Hi All:

I just got a new laptop and so I am getting everything set up the way that I like it. I have come across a problem with my sidebar though. I like to keep my bookmarks up all the time, but I want them to not be too wide and take up a lot of my screen. On this new computer, there's an addition 5 cms or so of white space at the far left of the tool bar. It had different buttons on it up at the top (one of them had something to do with AI) and a little gear down at the bottom of the space. I was able to remove all of the buttons up at the top, but I can't seem to hide the whole thing. I just want to see my bookmarks, without that extra customization sidebar. Is there a way to hide the spot highlighted in pink, but still have the bookmarks visible?

I have an account for standard support release versions, I am now using extended support release version 140.7.0 and a popup notification keeps nagging me to make a new profile. How do I do this?

Hello,

I'm unable to find the sync bookmarks,

I'm trying for a long time, in my iPhone and MacBook, both Apps are the latest, using the same email and the Bookmarks do not show in any of the devises.

Can you please help me?

I won't show my account information but when I try to access Amtrak's Guest Rewards site it goes into a loop. First it asks for username & password and accepts that with no problem. Then it asks for the code it sends to my cell phone and accepts that. And then it just keeps reloading various pages until I kill it. This is the error message shown in the log, it's repeated over and over:

NS_ERROR_ILLEGAL_VALUE: Component returned failure code: 0x80070057 (NS_ERROR_ILLEGAL_VALUE) [nsIFaviconService.replaceFaviconDataFromDataURL]

   loadFavicon resource:///modules/PlacesUIUtils.sys.mjs:220

   receiveMessage resource:///actors/LinkHandlerParent.sys.mjs:60

I'm running under Mac OS 10.13.6 The site loads fine when I use Safari (version 13.1.2)

Thanks

As I mentioned I can't seem to access my network folders. I only have this issue in this machine but I have my account on 3 different machines on the network with no issues. All have the same extensions and settings.

hello. my name is Andrew. im learning the language toki pona. great language! however, it does not currently have support in Unicode.

as a workaround to use this language online, people have been downloading a font called nasin nanpa, and adding it to firefox's font fallback system in the about:config settings, and using the fonts UCSUR characters, like these 󱥬, 󱥂​󱤴​󱤧​󱤑​󱦐󱤄󱤽󱤧󱤊󱥵󱦑.

[specifically, the font uses codepoints in the Private Use Area because the language's script is not yet in Unicode. ]

the changes are to these settings.

font.name-list.cursive.x-western font.name-list.monospace.x-western font.name-list.sans-serif.x-western font.name-list.serif.x-western

recently, this system has stopped working. this change breaks multiple websites, including many discord community's that used the font to talk online in toki pona!

it also presumably breaks other fallback scenarios. now im guessing that this has not been noticed as most fonts support every commonly used character, making this feature rather obscure. however i really would love this to be fixed, and so would the large toki pona community!

to see what i mean better, please see the below images. the last image shows a website that loads this font on it's own, showing what the others should look like.
