The Firefox version I used before was Mac version 136.0 After I updated to the latest version, I found that the fonts of the browser's tab bar, search box, and bookmarks became significantly larger. How can I change the font size?

On certain websites , the audio and video still auto play even though the option, "AutoPlay" is blocked for both audio and video.

Please see the attached screenshot which shows that auto play is blocked, it is circled in red. While the video has auto played, circled in orange with a timestamp of 17 seconds being played prior to it being manually stopped.

Please fix this issue.

I know, sounds stupid, but it is what it is. It happens rarely, only with Firefox on the secondary display from my laptop, via HDMI. It starts with some random few thin horizontal bars across the window itself, and soon, it turns off my display. It seems the bigger the window is, the more severe the issues. So full screen usually, it shuts it off and keeps it off. Not black screen, no signal style. I manage to get it out by Winkey+arrow. If i then put it back same issue. If i lower the width of it, it manages to stay coherent longer, but still resets the display with a quick black screen on page reload. The lower bounds on a 1920x1080 display resolution was 1515 pixels. At 1515 pixels, it works fine, once this is triggered, it's very repeatable on 60-70% of webpages. If i drag another window on top of Firefox, the monitor comes back up.

Before anyone asks: I have tried turning off hardware acceleration. I have tried putting firefox.exe to run on the integrated video card and on the dedicated 1060 Max Q videocard. I have cleared cache and etc.

This persists on a Windows session, across multiple Firefox restarts. A computer restart technically fixes it but i have no clue what triggers it. Laptop monitor works fine.

As the title states, every time I try to zoom into a page using pinch and zoom with my touch-pad, firefox nightly crashes. However, if I try to zoom in using CTRL+ and CTRL-, it works just fine.

I have tried to disable hardware acceleration but it didnt help.

These are the logs which I obtained from the crash reporter: AdapterDeviceID: 0x46a8 AdapterDriverVendor: mesa/iris AdapterDriverVersion: 24.2.8.0 AdapterVendorID: 0x8086 AvailablePageFile: 1012457472 AvailablePhysicalMemory: 10165415936 AvailableSwapMemory: 2000678912 AvailableVirtualMemory: 12812111872 BackgroundTaskMode: 0 BuildID: 20250613160838 ContentSandboxCapabilities: 119 ContentSandboxCapable: 1 ContentSandboxLevel: 6 CrashTime: 1750302886 DOMFissionEnabled: 1 DOMIPCEnabled: 1 DesktopEnvironment: ubuntu:gnome EMCheckCompatibility: true EventLoopNestingLevel: 1 GpuSandboxLevel: 0 GraphicsCriticalError: |[0][GFX1-]: RenderCompositorSWGL failed mapping default framebuffer, no dt (t=148.335) GraphicsNumActiveRenderers: 2 GraphicsNumRenderers: 1 HeadlessMode: 0 InstallTime: 1749869266 IsWayland: 1 LastStartupWasCrash: 0 LinuxUnderMemoryPressure: 0 MozCrashReason: internal error: entered unreachable code NimbusEnrollments: upgrade-spotlight-rollout:treatment,fx-accounts-ping-release-rollout-2:control,disable-ads-startup-cache:control,desktop-nightly-show-relay-to-13501-logged-out-users:synthetic-control,desktop-credit-card-autofill-global-enablement-rollout-nightly:creditcard-enable,enable-enrollment-status-telemetry-in-firefox-desktop:control,desktop-address-autofill-india-nightly-rollout:control,fpp-screen-avail-hardware-concurrency-desktop:control,hide-descriptions-on-newtab-articles-fix-rollout:control Notes: Ubuntu Core 24FP(D10-L1000-W0000000-T01) WR?

Any help or direction would be appreciated, Thanks!

can you give us the option to change the hotkeys/shortcuts please? is it possible for this to be an option for the future, I and I believe a lot of others switching from chrome to firefox would like the accessibility to change it as to what they're used to. Thank you very much for your time.

Why does Firefox mobile for iOS look different on my iPhone 13 pro max vs my wife's iPhone 12 pro max? both UTD on iOS version. I suspect that I must be missing something in settings, but cannot figure this out. See images below.

On my iPhone 13 Pro Max, the Firefox app has the nice home button, tab button, and hamburger menu button on the bottom (address bar on top both cases). On my wife's iPhone 12 Pro Max, it has the "+" for new tab, the 3 dots instead of hamburger menu, and then the tab button. I much prefer the layout on my phone, as does my wife, but I cannot figure out how to change her layout to match mine.

Any help would be much appreciated!

When logging in to a website that I use many times every day all day, all of a sudden I log on and all I get is a blank white screen. I have tried clearing everything, restarting Firefox, removing Firefox and re-installing it, rebooting the computer, starting Firefox in the safe mode but no change. The same problem shows up on three different computers on two different networks with two different ISPs. The website opens normally on Edge and Chrome. I would prefer to be able to use Firefox. Using version 139.0.4 (64-bit) on all three computers. I would really appreciate any help that is available.

I had to re-installed from 0 my windows. I was sure my Firefox account had all my passwords and logins because I had problems in the past regarding this. Installed Firefox into my new fresh windows. Hit the Sync bottom. Lastly, remove the old Firefox account login from old windows (for safety).

Now I checked password, 0 passwords saved.....

I am trying to re-sync but nothing happens...

I just need some help to stop techlorex from popping up as its constant and all day every day, There is no app and I search the system but nothing comes up, It pops up on one app I delete the app and it comes up on another one. Has enyone else had this problem and did you find a solution? Many thanks.

Firefox 139.0.4 changed behavior of text search (find-in-page). It now opens closed accordions and finds text in the <details> text (which it did not do prior to this update). This really breaks my webpage. I think this was changed for compatibility with Chromium.

Is there a config setting to change this behavior? Alternatively, can I change the accordion html so that Firefox will not search the <details>? (These are my private webpages, so I can edit them.)

Hello Team, I am having issues with Mozilla Firefox and Nightly Browser sound. If I use another browser, the sound is perfect. I have been using Firefox for years now and am accustomed to it, as well as Nighty, for all browsing needs.

hallo zusammen wo finde ich in firefox eine funktion, die mir die zuletzt angesehen und geöffneten tabs wieder herstellt?😐

in den einstellungen ist "Vorherige Fenster und tabs öffnen" angehakt.

es kommt aber wiederholt nach updates dazu, dass die letzten fenster und tabs nicht wieder geöffnet werden, sondern nur 1 tab mit der festgelegten startseite.🤷‍♂

muss ich mich damit abfinden, dass die letzten tabs hin und wieder im nirwana verschwinden? oder gibt es auch dafür einen tipp für laien?🙏
