Firefox 技術支援討論區

Lately, whenever I click on a file (be it PDF, XLS or whatever), it doesn't open. Instead, I see the relevant app (Acrobat, Excel, or whatever) flashing on the taskbar and I have to click on it to view the downloaded files. Not a big deal, but it used to be different, with the relevant app opening a window with the downloaded files (which makes sense: if I click on it to open - and not download - I want to see it now). Does this happen to you as well? I could not find any option to control this behaviour, and I don't think it is intentional.

I uninstalled Firefox which I had been using for years because when I tried to open it yesterday it said the file was corrupted and unreadable. I installed Firefox today but it didn"t import my bookmarks from the previous version of Firefox. I have windows 10

We have 2 desktop computers, both on the same wifi internet wireless network. On 1 we can ad the Ublock Origin extension no problem. But except for only 2 times, the other computer says installation aborted because add-on appears to be corrupt. Like I said, we have gotten it to load twice but both times it disappeared and now it won’t load. I’m not sure how it can be a connectivity issue, since they both access the internet from the same source. Is it that the problem system has Window 11 and the other 10? Why would it install twice and then disappear? Note that as a test I have uninstalled Ublock and then reinstalled it no problem on the Windows 10 machine. Does anyone know how to fix this? Thanks.

Every time I allow Mozilla to update Firefox, smooth scrolling ceases to work. Think maybe I've now had enough. Chrome can't be any worse than this.

Whenever I download a file Firefox downloads two of the same file. One is an empty file and the second file is the right size.

Example: I want to download a file called blender-4.0.1-macos-x64.dmg, when I start the download the first copy shows up immediately in my download folder called blender-4.0.1-macos-x64.dmg with zero bytes but another one is still downloading. Once that one is fully downloaded too I have another one in my download floder called blender-4.0.1-macos-x64-1.dmg.

Not sure how to prevent that, it is very annoying

How do I completely delete all traces of prior Firefox install? I believe my browser became corrupted. I uninstalled it and then went to the C drive and deleted all associated folders. As far as I know, I have no files saved as webpages but I do not know how to confirm in Windows 10. When I download Firefox I get the message saying a copy has been installed on my computer before. How do I completely remove any trace of Firefox so I can fresh install?

Unfortunately, I had an issue with some software on my Windows 11 laptop, so I contacted Microsoft support. Having explained the issues in detail, the software engineer advised that he was downloading a 'Windows 11 repair key'. Actually, what he did do, was wipe my laptop of all data.

Thankfully a Microsoft engineer using my OneDrive account managed to recover everything with my apps etc, however, all my browsing history and more importantly, passwords from Firefox have gone. As I am always signed into Firefox, is there a way of recovering them, or are they lost? I had to reinstall Firefox and logged back into the account, so does Firefox keep backups?

Thanks
