Firefox Community Forum

I installed Firefox on a Macbook Pro with Apple Silicon, M3. The installation was from the Firefox site, I downloaded the dmg and then dragged into Applications.

I find that playback of media stutters, and is choppy--not sure of a better way to explain it. E.g., YouTube videos and the Bandcamp player have "stuttered sound". Opening another site in another tab can make this effect worse. Likewise, trying to run Google Meet in a browser window causes basically everything on the computer to become very slow.

This still happens even if I go to "about:profiles" and then "restart with add-ons disabled".

But if I switch to another browser, Safari or Chrome, then I don't have the issue. e.g. I can play YouTube in the background fine even when running some compute intensive task.

I have also tried turning on/off "performance settings" and the "use hardware acceleration" checkbox underneath it -- neither of those seem to have any effect.

Activity Monitor showed that at most Firefox was using ~4 GB of memory of a total 48 GB, and the memory pressure indicator seems to be quite low.

I have run Firefox on other systems (e.g. System76, older Macbook Pro) with multiple windows open each having 20-30 tabs and never had an issue like this.

It really seems like it has something to do with how Firefox is interacting with the M3? Happy to learn I'm wrong. And happy to provide more details about the hardware or my settings if it would help.

When I try to access an http:// site, the link is upgraded to https:// regardless of this setting.

This broke after a recent update to the browser. I cannot specifically say which upgrade, but it worked a month ago, now it doesn't anymore.

It may be worth noting that this broke in Brave (based on Chromium) at the same time.

Ever since last update to Firefox, there are now intermittent drop outs in Audio, whether it's in media player(s) , youtube videos, or audio edited softwares.

And this ONLY happens when Firefox is open. 

If this isn't fixed soon .. and i mean SOON, I will be forced to switch to Opera Browser, where this Does NOT happen. Thank You

Can you help with this?

I am trying to understand how password less authentication with a FIDO2 security token works in Firefox over BLE transport.

Firefox uses authenticator-rs as Webauthn library which only supports USB-HID transport.

I am able to use a BLE security token to login to my google account however. How does that work if Firefox does not support that transport protocol?

Any help or direction to documentation on this topic is appreciated. So far I was not able to find an explanation for this online.

I would like to rename profile in roaming and local dirs for windows, but after I do it, addons are no longer visible in firefox. I guess I am missing something. What else do I have to do, when renaming profile dirs?

As shown in the picture, users should be able to change tabs freely on this page. But this caused some problems on my browser. These white tabs cannot be edited, moved or removed by me.

My first two tabs are always blank (even if I try to change it and add a valid URL to it) and other tabs can be changed normally.

When I tried to move a changed normal tab to the first one, I found that my changed tabs became blank and they could not be changed back to normal.

This is very annoying for me. Please help me fix this problem

I live in the UK and recently when going to the BBC.co.uk I get the website as BBC.com after a few seconds. I know that I usually see .com when overseas and this is normal. Why has this started happening while I am still in the United Kingdom?

after creating a new profile, and copying everything in the root directory to the new profile, including search.json.mozlz4, the default search engine setting does not get transferred over and is still set to google

Can you help me screenshot the webpages that I visited on July 4, 2024? I need it for proof that I tried to sign in to a course while their platform was down.

Thank you, Sayde

You can also notify the website’s administrator about the problem.

This is super frustrating. How to use Firefox for development purposes? There should be an option to add exceptions. I even went to settings and added an exception manually to no avail.

I'm going often through pain to use firefox for everything but then there must be a reasonable way to achieve the goals.

Please tell me there is a way to workaround this easily without compromising security of other sites that are being visited.

P.S. I can open same site with adding an exception on chrome.
