Firefox 技術支援討論區

I have been trying to locate the temporary file of the failed download video file. I was downloading a huge video file (78 GB) and the system froze in the middle of it. So I was forced to cut the power and restart the laptop. After restarting, I saw that my system drive is still filled with the temporary file (part), but I couldn't locate it and delete the temp file. It has taken up about 40 GB of my system drive space because the download was more than half way through.

When I started the download, I selected an external drive as the destination. However, I have been observing Firefox download behavior and I am pretty sure Firefox would download as much of the file to system drive as possible, until the system drive is full, then moving onto the destination drive, which has been a huge inconvenience, because of the huge video files that I am dealing with.

I have already cleared the file and the .part in the destination drive, but failed to locate the rest of the temp file in my system drive. I have searched the internet and found no mention of such problem. So I am seeking professional help here.

Attached is a screenshot showing how much space is used by checking the system drive properties, against the properties of all files in system drive (including hidden). The number doesn't add up, and there are 52 GB of files unlocated.

LibreOffice error: LibreOffice requires a 64-bit Java runtime environment (JRE) to perform this task. Please install a JRE and restart LibreOffice. https://hub.libreoffice.org/InstallJava/?LOlocale=en-US

I found nothing in FF extensions add-ons to facilitate this program/app. FF won't work with JAVA files but they provided no alternative. LibreOffice is the only free Office-like program/app. that is currently up and working today that I can find on any list I've pulled via browser on the first page or two.

It is so confusing to go to Edge or Chrome to use it - and hard to move things from FF over to Edge to get to LibreOffice - can't follow what I'm doing that way. I want to use FF. I feel safer there.

I don't trust downloading from random sites. Bait and switch for files. Malware. If there are is a trust-worthing d/l workaround pls tell me. I;m not up on them - not in the loop.

I need assistive technology really - this is just a start for me to get organized. You can give me advise on what keeps you swift and organized if you can too. Appreciate that much too. Thanks for any help.

The "Simplify page" function of the new Firefox version has zero rendering : letters too large, no text centering, no possibility to delete images, etc. So I would like to go back to the previous version of Firefox. Thank you for explaining to me precisely and step by step, as to a particularly bad person who does not understand anything at all. Why, when things are going well, does it take someone to change them, especially without asking users !!!

The 89.0 (64-bit) update to Firefox is a joke! When are fixes coming or is there any way for me to return to the previous edition. I cannot get used to this charade.

I think that Firefox is by far the most superior browser and this update is just so not Firefox. It hurts. It hurts really bad!

Hi,

I'm trying to download xilinx vivado design suite and cannot. The download fails for both Chrome and Firefox and the web installer fails as well. I've tried using a single file download, removing myself from my family's account and also tried using a download manager. I also deleted

This issue has been happening for about half a year now- I've been able to finish downloads by simply retrying them, but I've never tried to download a file this large (the single file download is roughly 60 GB and I would rather solve this issue than retry the download for a 60gb file).

Any ideas or suggestions why my downloads keep failing? Is this maybe an issue with my ISP?

Win10 with what was Firefox 89. I had already disabled the Proton UI on this installation, because it is horrible. Today Firefox decided to update to version 91. All of the Proton UI junk is back. I tried disabling it again, but nothing worked. Doing a web search, it appears that Mozilla has disabled the ability to turn off Proton.

I then set about to rollback the installation back to version 89. I found a Mozilla link on this, went to their ftp server and downloaded the installation files for the last version of 89. The installation went normally, but when I opened Firefox afterwards, a little box popped up saying something to the effect of "To keep your History and Bookmarks from possibly being corrupted, Firefox must create new user profile." I exited out of this and Firefox didn't start. I attempted to restart Firefox again and the same box popped up again. The only way to get past it was to click the accept button.

I did so and Firefox started. This was clearly not version 89. As the UI is junk, it took several minutes to find out that this was now the latest version of 92!!!! I'm absolutely positive that I downloaded the correct file. When I look through the update history, it doesn't even show todays version 89 installation as happening. What a piece of junk.

I then spent 20 minutes figuring out how to revert back to my user profile, not the new one that it had created for me. I then did some research on what had happened. Well it turns out that you can't actually rollback Firefox, despite what Mozilla says. For a while they have added "downgrade protection" which automatically creates the new user profile and stops your old profile from being accessed by it. So unless you want to figure out how to spend a hundred hours reconstructing bookmarks, passwords, settings, etc. it actually isn't possible to rollback Firefox. Doesn't this violate some Microsoft rules about being able to uninstall versions of software from within Windows? If you try to do this with Firefox and go back to a previous version it blows everything up.

Does anyone know how to actually rollback Firefox to a previous version, so that Proton can be disabled?

Hi since the last upgrade to 91.0.2 24th August I cannot download anything through Firefox. If my husband logs in on the same PC, he can download stuff and he is using the same version. We haven't consiously set up anything different. If I use Google I can downlaod as normal. What's happened? Thanks

After a new clean installation Firefox will not start. It generates a crash report in C:\ProgramData\Microsoft\Windows\WER\ReportArchive

AppCrash_firefox.exe_2dd4e427a29c7793432f8b232e348d43fa3ccf_b5a654c8_3fe69cd3-6f6e-4ee6-892f-f849836f0392

Can you help me to get Firefox starting?

Hi there,

I have a brand new Win 10 MS Surface 4 Laptop, and have tried downloading and installing various versions of Firefox:

From the the Windows Store Direct downloads (via MS Edge): Mozilla FF Win 64 Mozilla FF Win 64 MSI Mozilla FF Win 32

I have completely uninstalled and attempted to re-install each in turn. Attempts to open FF through desktop shortcut, Start Menu and Win-R FF.exe all seem to start but only ever get the briefest flash of a blue line along the Taskbar then nothing. Same happens starting Shift-Shortcut.

Nothing shows in Task Manager either after any start method. I'm pretty sure I'm not in 'S Mode' as I've been able to download, install and run WhatsApp Web, but I'm not wholly convinced I've cleared that up fully.

Thanks! E

Suddenly every file from every website is dangerous, clicking allow download does nothing. I disabled download filters both in settings and in about:config, yet everything is still caught and cant be resumed

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?

I was using Firefox and Owl (the addon).

I just upgraded to Fedora 36. I treid installing Owl and an alternative called "Dark Reader" and both cause a message stating they are corrupted.

I enabled dark mode in the browser. Google immediately changed to a dark background which I can more easily see. This site ignores the setting and is forcing me to work with very limited ivsion

I can barely make out the UI. I found what might be a solution at https://support.mozilla.org/en-US/questions/1356233 but after hours trying to read it I gave up and am wirting here.

It is very frustrating that other sites respond to firefox settings and your support site does not.

My old computer bricked itself. Hard drive, everything is toast. I have a new one but am wondering if there is a way to retrieve bookmarks, settings, etc. on a new Firefox install on the new computer, from my account perhaps? It seems to me that the last time I lost a computer and had to start over with Firefox on a new one everything reinstalled. I'm just about nonfunctional without all my stuff!

Hiya, So I have used the link below as a guide to get firefox to autoupdate on users computers via GPO.

Firefox is now crashing on multiple Computers, I think they might be crashing while trying to update themselves, as per GPO.

Any help please , crash report attached

Help! After many, many, happy, trouble-free years with FF (thanks folks) I just updated to FF 94.0. FF 94 is failing to use my saved logins, is silently failing to save new logins, seems to have forgotten my master password and won't let me set a new master password (which is probably a good thing!).

I see from searches here and elsewhere that the failure to migrate master password and login has been a serious issue, for a lot of people, for a long time, when upgrading FF. What I am still not clear on, despite reading many posts, is how to recover from this situation and seek your guidance on this.

In my profile I see:

• key3.db (last updated by old version of FF)
• key4.db (updated/created by new FF 94)
• logins.json (Seems still full of all my login entries and salted passwords, not touched by FF 94)

Thanks

Since "upgrading" to 95.0.2 firefox crashes frequently, and website, particularly game sites, stutter, repeat, and crash. Please tell me how I can go back to a working version. This unreliable version is just too frustratingly Microsoft for my mental health.
