Firefox 技術支援討論區

I am following all the instructions. It has continued to fail for the past year. I've uninstalled ff and reinstalled ff. I've tried creating new profiles. I can import everything into Chrome or from Chrome to MSE, but NOTHING will import into ff from any other browser.

Hello, Last few days Firefox keeps automatically downloading strange files like mLZrOMIV.htm icFSREgF.htm

They are 0 bytes, empty when I open in notepad and if I right click in download section and select copy download link I just get about:blank

I checked PC for viruses using Eset Online tool and Windows defender. No problems.

Has anyone run into something like this?

Hello :) For some time now my firefox doesn't allow me to preview PDFs. If I open it, it gets downloaded at the same time which I don't need. I already tried the thing with renaming the handlers.json to handlersOLD.json but it didn't work :( does anyone know how to fix this?

I am trying to add my Android phone as a device to Firefox. I initially invoked the code scanner next to the search bar, but got a message saying that the code had to be scanned from within the Firefox app. So I installed the app and followed these instructions entitled "Connect Another Device".

• If you haven't already, install Firefox on your mobile device. • Open Firefox on your mobile device. • Open the menu, tap Settings and select Turn on Sync. • Scan this code:

There is no Turn on Sync option in the Settings menu. I have looked in every menu item that appears even remotely related to syncing with a QR code or adding a device and come up empty.

I found this exact issue in two existing questions, but neither of them had ever been answered, which makes me less than confident that mine will. If there is a Turn on Sync option in Settings, and I just overlooked it, please explain step-by-step where I can find it. If there really is no Turn on Sync option, please provide an alternate method of adding my Android phone.

Thanks.

After upgrading to v91.8.0 I experienced a multitude of issues: unwanted folders, duplicate folders, incoming mail going directly to trash, and more.

How can I do a clean install of v91.8.0, getting rid of all existing formatting and data?

Well, the subject should be self-explanatory. But i need help in creating a Firefox account. Keep in mind that I am not eligible for Google Play because I use a PC.

When trying to save PDF's, firefox use to save each file as ex/ document, document(1), document(2) etc... now when trying to auto save it is making me input a name manually and won't automatically add the (#) to each file. How can i fix this? Thanks in advance.

I am switching jobs and want to sync my Firefox history from old work computer to new. Both run Windows. I changed the primary email associated with my account from the old work account to a new email. No problem. I synced the new email to my iphone no problem. Now im trying to download and sync Firefox to my new laptop. Running Windows and Im trapped in a crazy loop. I login with correct password to the new email and it asks for the authorization code and when I enter that, Firefox switches to the OLD email and asks for that password. I am not sure I have that password correct because i set the account up four years ago. Regardless, i cant sync my new laptop. But I was able to sync it on my iphone so it CAN be done with the email addy and password I am confident about. Please help.

'trying to sign on to zoom successfully, then once in I get a notification saying I need to download the lastest version, Ive tried 6 times bianary file and then nothing happens '

I have download set to always ask and consequently always get the, "What should Firefox do with this file?" dialogue box. 9 times out of 10 I choose, "Open with ... ". 10 times out of 10 Firefox also downloads the file. How can I stop FireFox downloading files I don't want ?

Hackers will be very happy now that Firefox automatically download their malware and backdoors. Thanks to Firefox, hackers will be able to infect millions of world computers and install ransomware and make havoc i financial, health, and other industries. Firefox will forever be praised by cybercriminals of the world.

Hi,Why is download showing up on nearly all sites I go to & HOW do I get rid of it permantently I can close it by hitting the X beside the Download,but it Should not be there Thanks Darryl

Why is firefox automatically downloading strange files I've never seen before? (MEUIVFJ-.htm and 3tHMwYhc) They look a little untrustworthy. My download dropdown suddenly showed me that one had been downloaded, and then a while later the other one was downloaded. Are these actual Mozilla files? Or are they some kind of scam/trojan/spyware? I just realized that two were downloaded last month as well.
