Firefox 技術支援討論區

I have been using Simple Tab Groups (STG) for a long time now. I am curious if putting tabs into groups saves any resources, i.e. is only the open group using resources (CUP/RAM), or is STG purely organizational in that all the tabs still use the same amount of resources as if they weren't grouped? If it is the latter, do you know of an add-on that would save resources? Thanks

I see a similar question on the forums from March 2021, but I'm having this problem now: when I go into icloud.com, it keeps asking for authentication - i.e. it presents a 6-digit code which goes to my phone/ipad, and I have to put it into the browser. After that, I'm prompted "Do you want to Trust this browser" to which I ALWAYS say "Yes", but it doesn't seem to work; the next day, if I try icloud again, it does it all over, like the "Trust" option is ignored. In settings, "Delete cookies and site data when Firefox is closed" is unchecked, Clicking "Manage Data" shows that cookies for icloud.com are saved. I've just added icloud.com into Exceptions to Allow to use cookies/site data, though I wouldn't think I'd NEED that if I'm never deleting them. I tried this with Chrome, and the Trust DID work; I can sign in with that browser and not have to put in the code.

What's up with that?

I need to turn off use Firefox email mask... I can't STAND being prompted to use Firefox email mask but I can't find a way to turn off that prompt.

JUST STOP THAT! It's infuriating that you're trying to force me to use something I DO NOT WANT!

Videos can't be played at higher playback speed Bug

On firefox, I cant play videos at higher playback speed or it'll only play audio or video will endlessly buffer. Using user-agent spoofer and changing to chrome makes it a little less worse but still the problem sustains. On Brave, the video doesnt have any effect of higher playback speed rather it'll make the video buffer and have very strong red contrast.

Please can you help?

On spotify web player in firefox there is a delay after skipping 15 seconds forward or backward in audio. Only on bluetooth speakers. But doesn't happen on Chrome. Anyone got a fix or can help?

on some websites it says -1 tells Firefox to automatically determine the size of the cache based on your physical disk and setting it to 0 would effectively disable any disk cache entrys.

so are this informations true and if not, how do i still let firefox automatically determine the size of the cache based on my physical disk?

When I try to login to the Tesco website I get this message: Access Denied You don't have permission to access "http://www.tesco.com/account/login/en-GB?" on this server.

Reference #18.26cc19b8.1700669440.3c27026b

I have cleared History plus cookiies and site data and cached web content

But I'm still unable yo login to this site.

You can see below my choices for - `1` for light, in `layout.css.prefers-color-scheme.content-override` - `0` for light, in `ui.systemUsesDarkTheme`. - "Light" website appearance AND theme().

But why some websites still darken and blacken background ? Examples are https://superuser.com, https://softwarerecs.stackexchange.com.

This mishap DOESN'T happen in Troubleshoot Mode. But I don't have the Dark Reader extension.

Cross-site Backup

I have been having with YouTube for a couple of days. It asks to turn off ad blockers. I have done so and it still requests to turn ad blockers and still won't allow viewing. YouTube works on other browsers.

I am sure YouTube is playing games but can you help?
