Firefox 技術支援討論區

Autofill has been working perfectly fine until yesterday. There's not even a manage addresses in the privacy and security settings anymore.

Autofill card still works, but not addresses.

I have 3 computers (2 desktops, 1 laptop). I want to permanently delete approx 300 unused/unneeded passwords. I deleted them from computer #1, then logged out of Firefox. The new count was 346 passwords.

I went to the second computer, deleted approx the same number from computer #2. The new count was 324 passwords I returned to computer # 1 and logged back into Firefox.

Within a short time, computer #1 is at 759 passwords, and computer 2 is at 691 passwords.

How do I get the deletions to be permanent? It's the second pass at doing this and I'm FRUSTRATED.

I'm experiencing a problem when I visit certain websites, like 'https://mui.com/x/react-data-grid/'. Every time I try to access this site, the page starts an infinite reloading loop, preventing me from using the website normally.

"Your browser is managed by your organization" suddenly appeared OS:Win11 Certificates: "ImportEnterpriseRoots" I've tried: Reinstalling Firefox Installing Firefox Developer Edition (it disapeared for few days but it was back) Deleting the registry key for it (after restart it appeared again)

 I have Avast and Malwarebytes but this has never happened to me before with this anti - virus

For years, I have used print to pdf in Firefox to generate pdf files of long web pages. It always worked. But lately, I noticed that huge numbers of blank pages are inserted in the pdf file, seemingly at random. I looked at the HTML source, and could not see anything that obviously triggers the blank pages. For example, a web page that ought to print to about 35 pages generates a file of more than 600 pages, with most of them blank.

I can use Microsoft Edge as an alternative, but pdf files from that browser strip out all the color, and are nevertheless super huge, about ten times larger than the ones from Firefox. E.g. the file mentioned above, about 35 pages, would be about 1.3 MB from firefox, and 12 MB from Edge. So getting the file from Firefox would be nice.

Is there a reason why print to pdf is behaving in this strange way, and anything I can do about it?

I switched from windows 10 to 11 and to a new laptop. Here in my new laptop Asus tuf 15 ,even though it has better RAM , internet connection, cache memory, cores the FIREFOX doesnot function properly. It's extremly laggy specially when I use YOURUBE . In my earlier HP laptop with 8 GB ram I could use 10-15 tabs at one time .It would still not lag . It could do web development at the same time I could watch youtube tutorials. But now I barely open 4-5 tabs the youtube starts freezing up to the extent that I really get frustrated. Please so something or I will have to switch to BRAVE browser or something.

No crash report, no trace, no anything. I click "Save [insert] as...", and Firefox hangs and stops responding. Windows automatically shuts it off when clicking. Launching Firefox again sometimes says there was a problem reloading the session, but that's not guaranteed.

AdBlock has not made any updates for Firefox for eleven months. Do they just not care, or has Mozilla rejected them? The internet is terrible enough as it loves to scam all users on all sites.

When you add a new bookmark to a folder it's added at the end of the existing list.

Is there a way to make Firefox add it at the top of the list, instead?

I found an old answer, but, sadly, the extension granting my wish is no longer.

Also, I already know about sorting, but it's not what I need, because I'm doing a lot of manual bookmarks reordering and sorting will nullify it.

Thank you :)

When watching a video on YouTube, the sound suddenly stopped playing. Currently, sounds in video and audio are not played on all sites.

The problem is only in the browser. Audio and video files are perfectly reproduced by the VLC player. There is also sound in the Chrome and Firefox ESR browser.

My actions. 1. Disabled all extensions 2. Clearing history and deleting all cookies

My browser - Firefox Developer edition, version 123.0b9 OS - Debian 12

P.S. I have been using the developer edition for many years. It seems to me more convenient and faster compared to regular Firefox. I really don’t want to delete the customized browser.

I need help with audio in browser...

Many thanks!

Hi. I can't access my add-ons that I installed. When I click on the extensions icon it doesn't open that little menu like it does for other people, but it takes me to 'about:addons' in a new tab. I also want to pin my addons to my toolbar which is also not working. Please help me out

I am running Firefox Developer Edition (123.0b1) on Windows 11 and every time I start Firefox it maximises and then resizes to a set size with the maximise button set to restore size mode (I.e. the window thinks it is maximised). I have followed the steps detailed for this question: https://support.mozilla.org/en-US/questions/1411093 however that does not resolve my issue. This has only started recently after I turned the laptop into a tablet and back again. Once I "restore" the window and then I maximise the window it works as expected. However it is very annoying. Also if I start another instance of Firefox this new instance does not exhibit the same behavior.

Computer: HP Envy OS: Windows 11 with all current updates and as far as I can tell AI is turned off using a group policy.

How to restore cookies which have been deleted by mistake. I have accidently cleared all cookies from the cache. however, some of the important information from one of the softwares (Zerodha) was stored in the cache as cookies. Now the entire data is lost. How can it be recovered

Attempting to log-in on Twitch with Firefox Browser - Developer version 122.0b9 (64-bit) is currently not possible, repeated messages are prompted by the Twitch website about "unsupported browser" and to contact browser support to resolve this issue.

Clearing cache, disabling extensions did not work. Using regular Firefox works without issues, only noticed this being an issue after most recent update for Firefox Dev browser.

Side effect as well since update is that any Cloudflare captcha is impossible and all website that use Cloudflare to "authenticate" that I'm human just outright fail or continue indefinitely.

I change nothing in my settings and I am now on Dark background everywhere despite having: - forced the system settings (OS) to stay in light background - in about:preferences appearance I've manually selected (forced) the light background - in about:config I've tried to switch the browser.theme.content-theme to "1" (instead of "0")

this is really frustrating, I would like to get a better "reading" of what happens, as an Engineer I am happy to also squint at logs if needed, please consider adding a preference / settings change log file

I have had this problem for a while. I am not sure what to do so that I can fix this. Whenever I open a pdf or any application that can be opened in the browsers shows me two options for firefox browser. I attached a picture that will make it obvious what the problem is.
