Firefox 技術支援討論區

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

Unable to install Firefox on WIN11. Wants to create a profile but get "An unexpected error has prevented your changes from being saved. (This is a new Desktop unit I received today and have not had any problems with WIN10.

I was trying to download audio from some of my private youtube videos, but they saved as mp4 files. This did not happen on my phone so I decided to download everything there and send them to my PC using discord, but when trying to download what I could now see was .mp4 it still saved as mp4. If it's of any use the service I used to ripp the sound was mp3juices.

I received a message from Fire Fox that I should update. Now I have 2 Fire Fox icons and I need to know how to determine which one to delete. Then I need to know how to transfer my favorites and history to the one I keep. They both show favorites and history. I'm a rookie at this so if you can explain step by step it would help, thanks.

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?

Now on new PC, win 11, had win 10 on prior. FF installed easily, everything migrated, signed in etc. But--Firefox menu bar is no longer displaying icons for a number of things, notably for home screen (house icon returning me to home page) and for my password manager, Sticky Password (reinstalled here), as well as several others of lesser importance. I suspect there's a single on/off toggle for these somewhere but I can't find it. Thank you for your assistance.

Hello Why is it that every time I open Firefox, I get a message asking me to update? If this persists, I may need to use another browser. I keep pressing the "download" button for the upgrade but nothing happens. Could this be the issue? Please help as I do not want to change my browser. What have I done wrong that the upgrade is not happening automatically? Thanks

My primary machine has (FF 88.0.1 64-bit) has all the FF tweaks for privacy and annoyances I care to have. Last outstanding issue is floating videos -- but that's posted as another topic by me. Big questions:

1. Can I bring FF on the three other laptops and server to the same FF revision level at this machine and copy across all files that would capture settings this machine's settings/changes in Config and Policies ?

I currently make quick work of syncing UBlock and AdBlocker on all machines by simple export/imports of text files. Everything tweaked exactly the same on every machine with respect to FF is what I am after...

Firefox updates use the term MSI, but never do you explain what that means. Come on guys step around the counter and act like a user. Not only what does it mean, but what are the differences between MSI and the download without MSI?

Today using Firefox 93.0 on my Windows 10 home computer I opened the browser to my Audible library on Audible.com and selected a book to download. The browser download window opened with the book file name but the extension wasn't .AAX but had been changed to .MP4. This did not happen when I used Microsoft Edge nor did this happen on my Windows 10 laptop which was still running Firefox 92.0. Once Firefox upgraded to 93.0 on my laptop I now get the same problem as I get on my home computer.

Audible technical support looked into the problem and found that this change wasn't caused by their servers.

I have discovered that if I change the file extension from MP4 to AAX I can load the audible book into iTunes and sync it over to my iPhone which is able to play the file as an audible book. This indicates to me that the actual AAX file was not converted to MP4. For some reason only the file extension was changed.

I wasn't able to find any setting in the Firefox browser that corrected this problem.

I was using firefox with same account. operating system of my computer crashed. Now i have again install windows 10 on my computer. I have login with same firefox account but my stored data like password, bookmarks etc are not syncing this time even after pressing sync button several times. I have lost my stored information. This is not right thing happened to me because important information was synced with ny accont. Kindly help me.
