Firefox 技術支援討論區

I had to format ( factory reset) my laptop. After installing mozilla, and sync my account is like new. All previous data i.e. Login, password, bookmarks, etc all are missing and i tried about:profiles method which is also not working. What should i do to recover my old data?

Original question, Why doesn't DarkReader add-on work on home page?

Answered with: Internal pages are protected from addons. But you can simply select the dark theme in ≡ -> Customize.

Possible reasons not to work:

1. The poster was an alien
2. 42 (See no. 1)
3. Mozilla devs just hate us. When we (have to) come for answers here, from a comfortable dark web - whether using Dark Reader, or some other means - they purposefully BLAST us with bright white pages so that we will never, ever use Firefox again and uninstall it right away and move on to something else (less idiotic).
4. Seriously, though, see the answer in context was an alien.

So, who can tell us how to get around this, please? We get it, whatever: support.mozilla.org is, somehow, a local page - or, something - and it can't be styled, but how do we get around this BLINDING WHITE LIGHT? Thank you so much.

^^ addons.about ("addons.about-scheme") can be styled, Library (Downloads) can, Options (about:preferences) can and also about:about and a bunch of abouts can, also - only this website is locked like this, to torture people, why...

EDIT: Screenshots attached illustrate that, as suggested in the first thread from years ago, Dark Theme had been applied and it makes no difference.

Hello, just an ordinary user here. I am using Firefox long ago, 'till I switched just today. I ran basic security tests until I got to http://whatismybrowser.com. It says that I'm still running on FF78 but actually I am on FF83 [https://whatismybrowser.com/w/N7QEGDA] .I refred firefox and reset to the default settings still, the problem persists. What is this all about? What am I should do? Thank you so much, I would appreciate your help.

I have previously not had this issue, have had no problem viewing videos on this particular website. Recently I've had a raft of of issues (since the latest Firefox upgrade??). In this instance, the website is https://www.sbs.com.au/ondemand/ I am signed in as a member. Whenever I try to play a movie or TV show, I get this message:

Video Playback Error Sorry, we’ve encountered an error playing this video. If you have an ad blocker turned on, try turning it off or whitelisting our website before trying again. This may prevent you from loading videos.

I'm PC illiterate so I have no idea how to turn off an ad blocker (as well as Firefox being my browser, I have Quick Heal Anti-Tracker installed). Can someone please provide some help with REALLY BASIC instructions (ie. as if you're talking to an alien who has never used a computer before!). TIA

I also am unable to sign in to my YouTube account so I can watch videos I've subscribed to (I can view videos otherwise on YT). When I attempt to sign in, I get this image (below).

I have emptied cache, deleted browsing history etc, makes no difference. I can access and view SBS and YT on another browser, just not on Firefox.

How can I sign up for Mozilla (firefox) forum?

I have an account, but won't recognize my credentials. They ARE correct.

I try to set up a new account and the security question "how many letters in Mozilla" doesn't work. The answer is 7, but says it's wrong. WFT?

Its 2020 man!

Why are we (Mozilla community) still missing content casting feature just like Google Chrome and other browsers. Even the new Microsoft Edge Chromium have that feature. I usually stream a lot of content and this feature, for me, is indispensable.

Furthermore, I am not asking for any workaround or extensions. There should be a native casting feature on Mozilla Firefox too just like other browsers.

I was buying online from JB Hifi website, when I got to the checkout page, Firefox closed itself out. Tried several times and results still the same. I don't have that problem with Microsoft Edge. What is wrong? I recently had a virus scare & re-install Firefox. Thanks!

Hi Everyone,

I cannot access my Firefox account created with 1 of 2 email addresses I use, I'll call this emailA, and do not have Firefox in an Authenticator app nor can I find the recovery code. The account did have a secondary email address listed. I'll call this emailB. EmailB also gets all alerts when there are changes to the EmailA firefox account such as new system logins and password changes.

Given that emailb gets notifications regarding the account is there a way for me to gain access to the account with emailA as the primary address using emailB?

Failing that, is there support who I can contact to have the account under emailA deleted?

Regards,

Chris

Hello... I'm using the latest version of Firefox and the latest version of Windows 10 ... I'm curious when I do the following with the browser, click History, select from Clear Recent History, have it set for Everything and have all the boxes checked, how is it when I visit a certain website it still show me log into there website? I thought if I delete the everything( cookies, cache ) this wouldn't be the case. Is there a way for the browser to be completely clean from all? thanks

I either lost or deleted all my logins and passwords. Is there a way to retrieve them? All files are backed up on my external hard drive if needed to restore

Thanks

I need help! Everyday I have at least 8 Chinese Hackers that show up on on the top in the list of websites visited on my Firefox. The entire page is in Chinese with Chinese pictures. Please see the attached images. I have no idea how long they have been there prior to being so bold to openly show themselves. I certainly have no idea of what they have uploaded or downloaded on my laptop. How can I get rid of them and what can i do to prevent them coming back? I know a lot of weird things have been going on in my computer that I have absolutely no reason nor explanation for. this has been going on for at least the last couple of years or more. I have had 3 computers to crash in a short period of time which I feel they have done. Spyware shows I have had a keylogger for a long time but all of the files it takes me to are protected and I have not been able to delete them. BillCowanjr@gmail.com
