Firefox 技術支援討論區

I've been using Firefox for two years on my laptop (currently using Chrome just to write this), and today the browser closed all my windows taking me back to the desktop. When I went to reopen Firefox, the desktop icon had been removed. I redownloaded it and it took me back to my previous windows even, so I didn't think anything of it, but I noticed that the desktop icon was gone once more and yet the browser was still open. It was fine for a couple of hours, but then the "Windows Defender" pop up kept coming up telling me there was a virus and to restart my computer. I restarted it, and went back to download Firefox again, but now it keeps saying "Failed—Virus Detected".

Team, I cannot find google authenticator extension in the add-ons manager. i am trying to migrate from google chrome to Mozilla Firefox but I need the google authenticator add-on.

I'm trying to download Firefox on a new computer. It downloaded the install program at least 6 times in about an hour, but it never finishes downloading. How can I avoid this and get it to actually download Firefox?

please note it seems possible that this category is specifically for download of firefox, this is not so. opting for this category given the possibility that that theory is mistaken, and due to not seeing any other category that might be more suitable

using firefox developer edition (also couldn't find an individual category for this), and when downloading any files, it saves automatically without asking where/what to name it etc., as preferred. but specifically for pdf files, it always opens them in a new tab upon completing the download; this can be very frustrating when downloading larger quantities, especially with it switching to that file tab and away from the source of downloading. firefox is not even the default for opening pdf in the first place

looked through preferences for anything (and tested anything that looks potentially relevant, to no avail), looked for a solution online from various sources and search methods, no dice

how can this be disabled?

Switching to a new Mac computer and trying to get the bookmarks back, especially the tool bar. I did the export and import steps. Both export to HTML and as a backup file. Next I airdrop it to the new computer and try and import it there. Seems to work (no errors), but no bookmarks. I have looked at google videos and tried searching you help area.

Chrome i just log in and it comes over, I remember losing everything in firefox last time I got a new computer and had to rebuild from scratch. I can't afford that again, please help.

I downloaded the new Firefox update and now cannot go anywhere from the Mozilla icon except my email. When I click on a link or enter a new address, nothing happens. Sorry I downloaded. Everything worked perfectly before. I've used Mozilla for years and this has never happened. I'm fed up. I do not want to use MS Edge.

I had to switch to a new Windows 11 laptop. I installed firefox my favorite browser. It has been a disaster. after 1 week of trying different settings I have been unable to log into Facebook, Ally Bank, Netflix and others. I have changed the delegated credentials from true to false and it doesn't work at either setting. I am either getting SSL errors, "Pardon the Interruption" on netflix and some sites just say "Unable to log you on". Please note that I can successfully log on all the apps on Edge.
