Firefox 技術支援討論區

Due to repeated issues over a week, I uninstalled Firefox days ago. Tried to Reinstall it repeatedly on same device several times. It was working before..BUT it keeps showing its downloaded on Settings but Firefox download page keeps showing "DOWNLOAD" Tried several times. Not my computer. Nothing works to resolve it.. Windows 11..

I have Windows 11 and Firefox 124.0.2. Firefox keeps asking to reinstall. I think it is because I keep getting the message that it fails to check for updates. I don't know if I have installed the Microsoft Firefox or the direct Mozilla Firefox downloaded. Maybe that is the problem, but I am not tech savvy. I have used Firefox for many years and like it. I am also too old (83) to deal with these problems. Help!

I wish to install and use the Firefox browser on my old 64bit Windows 7 laptop.

I believe the last v115 will be the last Windows 7 compatible version of Firefox, if this is correct where can I find this or the correct version of Firefox to download and install on my Windows 7 laptop?

The Firefox website only seems to provide v119 now.

Thanks, Graham

I was in italy when I first created my firefox account and by default it choose italian as language. All of my search results are in italian even though in browser settings I choose English as preffered language. Now I discovered that actually my firefox profile is in italian that's why I see results in italian. In the profile settings (https://accounts.firefox.com/settings), there is no option to change the language. Please help.

I can't figure out how to install Firefox on Windows 11. Their link gets me to APPS in Setting but from there I'm lost. I can't find in APPS where to allow for apps from third parties. I think MS does this on purpose.

I just got a chromebook from my work, and I'm unable to install firefox. I've tried searching for firefox download and clicked on the top result from Mozilla, but once it has finished downloading, I try clicking on the freshly downloaded folder but that just lets me see the folders and files within the big folder. I haven't had this experience before when trying to download firefox, but I'm also fairly new to using a chromebook. So I'm not sure if my issue is with the chromebook/OS, or maybe since it's through my work, I'm limited in what apps I can download? Any advice would be greatly appreciated. I'll do my best to attach a screenshot of the folder that appears.

I found that Firefox can automatically generate a QR code for each URL, which is a powerful and useful feature! I'd like to know if this QR code has an expiration date.

My computer crashed and I have to reinstall everything now. I was using Firefox 78 with Mac OS 10.11.6 el capitan. Please provide link to where I can download this version.

I broke an old computer and have my logins from it on a backup drive in logins.json and key4.db. I can't work out how to transfer these logins to my new computer. I've tried creating a new firefox profile since I am nervous of losing logins that are on my new computer, but then I am totally lost.

I cannot access certain email documents because my pop up is blocked. I have tried a number of searches as to where to disable the pop up for firefox but keep hitting dead ends.

I wanted to move my FF profile from my old PC (Firefox ESR for Windows XP SP3 32 bit 52.9?) to my new PC where I installed Firefox ESR 91.11 64 bit.

Moving the profile was no problem. I simply copied it on an USB-Stick and moved it to the profile folder of the new installation.

Starting FF works and it remembers all old links, settings and usernames for the sites I visited - BUT it does not store any password I enter after having moved the profile.
