Firefox 技術支援討論區

I have tried both Google Authenticator and Guardian for use with Mozilla 2FA. I have tried scanning the QR code on my PC multiple times on each authentication app and retrieving multiple codes each time, but all entries stated "incorrect 6 digit code" on my PC to enable 2FA. I am not sure how this is not working. Both authenticator apps identified my correct login email address associated with my Mozilla account so I know it must have something to do with whatever is happening on the back end at Mozilla for my account.

Also, I have read a few posts in the Mozilla support knowledgebase regarding this very same issue, but did not see any resolution. I would really like to have 2FA. Can someone please contact me about this?

I've been unable to play twitter videos at all. For videos and audio posts on other sites, there's usually a delay for a couple seconds before it plays. I disabled all my add-ons and it made no difference. If I try to play 2 different things at once, both of them will chug if play at all.

Does anyone know what the cause might be? I tested videos and audio in another browser and they work fine.

After installing the new version 106.01, restoring recently closed windows in History doesn't work even though it is highlighted as being active, but nothing shows or happens when pointing at and clicking on "Recently Closed Tabs".

(I accidently closed one of my two windows and therefore lost all my tabs.) (I know I can restore the tabs one by one, but that will be a huge task.

So what can I do to restore my lost Firefox window?

Thanks in advance. Jens Giertsen Denmark

Firefox / ExpressVPN ISSUE (21st Oct 2022)

My desktop computer's operating system is Windows 7 Ultimate with Microsoft Extended Software Updates (ESU). 1. The office software is Microsoft Office 2010, from which I use Outlook 2010 to send and receive emails. 2. The only browser that I use is Firefox. 3. With Express VPN to mask my IP address (Firefox browser extension for expressVPN enabled) 4. And my internet package provided by Avast Premium Security. Up until about a month ago, these 4 packages ran sweetly in the background protecting my computer from all devious activity. Then on return from a short break, I noticed that every time I switched on my computer and activated expressVPN, I could not access the internet or send/ receive any emails. I pay a yearly subscription to Avast Premium Care which offers a superb 24/7 service, where they can remotely connect to my computer and repair it whilst talking with me on the phone. Using their help, I quickly discovered that when Avast software was enabled when Firefox was running, I could access the internet and send emails. But when expressVPN was also running, I could not get internet access or send/ receive emails. Then it was by a process of elimination I proceeded to try and discover which package might be the culprit. With both Avast and expressVPN disconnected, Firefox works perfectly! But with Avast still disconnected, I switched on my VPN and instantaneously, the internet was cut off! It was then that I contacted expressVPN technical support for help. We changed every single expressVPN setting possible, to no avail! And considering that all the VPN in essence does is mask my computer's IP address, he concluded that the issue had to lie with a Firefox setting! I then proceeded to check I was running Firefox latest software, deleted all browser history and cache and changed the network settings to no proxy - to no avail! In desperation, I turn to your technical team to resolve this issue for me, as I have no idea what has happened!!! This system has worked for years without a hiccup. Now I'm at my wit's end and need my computer running flawlessly to continue my business work as a matter of the utmost urgency!

Please return the header to the white background with black lettering. NO COLOR PLEASE! I don't want any changes to the setup or color or anything. Please return to original headers-----BLACK ON WHITE BACKGROUND. NO COLOR OTHER THAN BLACK ON WHITE1

I've got Mozilla VPN on my macbook, but firefox shows DNS leaks when tested using https://mullvad.net/en/check/

Fixes already attempted: - DNS over HTTPS set custom provider to https://doh.mullvad.net/dns-query (from https://mullvad.net/en/help/dns-over-https-and-dns-over-tls/) - still leaking - using custom provider in about:config set network.trr.mode to 3 - no sites load - using custom provider set network.trr.mode back to 2 and set media.peer.connection.enabled to false - still leaking

Any suggestions?

Recently I started a new job and received a laptop, so I've been setting up the laptop with all my stuff, including Firefox. At first I used Firefox's account sync feature, but it doesn't sync everything - my extensions' settings (not the extensions I have but what their settings are), my toolbar customization, all the sites I'm logged into, and maybe some other things are not sync'd. So instead I tried a different solution which has worked for me before - copying my profile folder on my PC and pasting it into the laptop. This mostly works, except suddenly Firefox warns that a lot of my company's websites are a potential security risk with the error code SEC_ERROR_UNKNOWN_ISSUER. I can get past this, but the real problem is some of these websites - namely GitHub - don't load any CSS anymore. I can access the site but it's ugly. Normal GitHub works, only my company's GitHub (which has a different URL) doesn't.

If I switch back to the other profile, it works. But I'd really like to avoid having to manually sync up my extension settings and other things. Is there any other way to resolve this? Thanks.

Is this a known issue for the new update? Whenever I try to click Recently Closed Windows in particular, it just does nothing. It has the grey highlighted bar that shows it wants to do something, but then does nothing. About 1 out of 100 times when i click Recently Closed Tabs, it WILL open to show my recently closed tabs, but generally does the same thing as Recently Closed Windows. I know I have recently closed tabs because I restored session and it is currently showing all my old tabs I had open prior to the update. I also tested to see if my recently closed had just reset by opening a new window and closing it, but it still just does nothing. I use the Recently Closed Windows quite a bit and it's quite irritating that it appears to be broken.

After the last update (106.0.1) Firefox no longer saves my open tabs after closing and then re-opening. Even though "Open previous windows and tabs" has been checked under the Startup section of General Settings. So I've now lost dozens of previously open tabs since this was unexpected.

Now, upon re-opening, I get a single empty tab. This seems to be a glitch that came with this recent update.

I tried contacting Mozilla Customer Service, but there is absolutely no way to do it. You customer service leaves much to be desired.

You updated your unstable system. It did the update, but now my saved passwords are missing. If your system deletes the passwords, what kind of safety do users of Firefox are guarantee? If this issue is not resolved, I will leave and delete your browser NEVER to use it again. In addition, I created a Firefox account long time ago to supposedly have my passwords secure. At this point all the passwords are missing. What security is your system providing?

Hello, I was on my Facebook page and was about to share a link, and was denied further access. This message keeps coming up as I try to logg in again: Secure Connection Failed

An error occurred during a connection to www.facebook.com. PR_END_OF_FILE_ERROR

I opened an account with roboforms yesterday to store my passwords. They say the extension I first installed is not working, tried to uninstall & reinstall but no longer have the link to do that.

thank you, I am new to all of this & find it a nightmare to deal with.

So you are in private mode for a search. Within the search hits, you find a link you want to visit, so you click on it. Will you remain in "private" mode while at the linked site? Or do you lose the "private" as soon as you leave the search window ... ???

I have Firefox 106.0.1 SNAP install on Ubuntu Mate 22.04. The default language is Spanish, I added English and Italian dictionaries. When I write I'd like to choose among the three languages for automatic correction, but Firefox only shows Italian and English. Why? How can i fix it?
