Firefox 技術支援討論區

I am currently running Firefox on High Sierra 10.13.6 and have been advised that that OS will soon no longer be supported. I did have an option to do an update to ESR 115.1 in my Firefox app, however I was not home for a few days and when I returned planning to do the update it was no longer available. Now it just says my Firefox is up to date with 115.0.2... how can I get the update to the ESR 115.1? Thanks!

I have had this issue before and uninstalling and reinstalling has fixed it in the past. Today when I opened firefox it prompted me to update , which I did without thinking. Subsequently, it stopped working. I have tried: restarting my PC, running in troubleshooting mode( it wouldn't even open when I tried this), uninstalling and reinstalling using the internet installer, uninstalling and reinstalling using the offline installer ( tried on multiple hard drives, so I don't think hardware failure is the issue), installing an older version of fire fox, and installing the 32 bit version instead of the 64 bit version. The attached images show what displays upon trying to launch firefox. nothing loads, not typing an address into the search bar, not clicking on a bookmark, the only UI element that will display is the 3 horizontal line setting menu.

Yesterday my firefox updated to version 96.0. It changed to screen to dark theme. I prefer the light theme and need help to change it back. Thanks

I have Mac 10.12.6 on an "early 2009" 27" iMac. I'm waiting for the new 27/32inch iMac until I upgrade hardware and operating system. The release notes with FF V115 say in part " Users on those operating systems will be migrated to the ESR 115 version of Firefox."

I want to clarify that when I update to FF 116, FF will automatically install the ESR version, or will I need to do this manually? Also, will this update take a long time, like FF will be installing a totally new (ESR) version, rather than "just" the usual update?

After today's update to version 98 Firefox keeps saving files to the Downloads folder when I don't want it to, I just want to open them, but not keep them, with this new behaviour the Downloads folder keeps filing up with useless clutter.

For example, before the update, when I downloaded a .zip file, a pop-up would show up asking if I wanted to save the file or open it with an application. If I chose to save it it would be saved to the Downloads folder, and if I chose to open it nothing would be saved to the Downloads folder.

After the update, when I download a .zip file, Firefox always saves the file to the Downloads folder, even if I choose to open it.

Can you please tell me if there is a way to make Firefox behave like in the previous version?

Hi, new updates on Version 98.0.1 quite a hassle for me. It auto-download all my files even when I just want to view. Is there any other way to disable this feature? I opened Setting>Download but there is no disable button or checkbox for that. Please help me. Thank you in advance.

My job requires me to download and open files in new tabs consistently. However, when I download these files, I don't want the download panel to obscure my vision. Can I disable it?

Hi, I have spent hours this morning trying to diagnose a problem with Firefox Update 115. It is Unstable and I can't Stream Music from Youtube or even Amazon Music. Web pages from sites I use everyday are out of order when displaying text as well. It's a real mess. Now, here's the kicker, I haven't been able to stream my music from both aforementioned websites, but get this, if I use the Incognito Browser, Music streams No Problem. Seems like you guys broke something in the main FF browser. I have spent hours trying to debug this and have concluded that your most recent Update has broken streaming links. I can't rollback the Update and that is even more frustrating. Please Fix This. BTW, your Help Pages really stink. Sorry, but they offer no help when the problem is clearly FF. Kind Regards, Joe White

I got a new computer so I created an acct and set all my open tabs and history to sync. It wasn't intuitive to my not techie brain, but found out how to open all the tabs on the new computer. However, they don't open in the same order (makes it almost useless when you have a lot of tabs), and the tabs don't have their associated history.

Is there some way to have Firefox open tabs and history in the same state on the new device?

My wife has an older Mac. About a week ago, a pop-up from Firefox told her to update her program. She loaded in the new one and when she tried to open it she got the message that her computer was too old for the update.

We had to reload the most recent update which had been running on her computer.

Now, none of her bookmarks show up and the bookmark toolbar will not display near the top of the screen as it used to.

None of help items online are of any use because what they say will show up on the screen (such as when you enter "about:profiles") is not what shows up on her screen.

Is there any way to recover her bookmarks, passwords and other saved data, please?

This is going to be long sorry. A lot has transpired

My son was using 78.15esr. I upgraded it to 91.3esr. After the upgrade the browser worked; tabs loaded, surfing was fine, could go into settings and about:config was fine.

He went to watch something on Netflix. Netflix complained his browser was not supported and he needed to upgrade to the latest version - which at the time was 91.3esr.

In frustration he installed Chrome. When he tried to run it he was told software restrictions were in place. I had not set any restrictions, and I checked secpol.msc and there were definitely no path rules defined. If restrictions can be set in group policy I had not set them because I am unaware of them.

So he installed Microsoft Edge, which installed VC runtime for 2013 and 2015-2019 for both x64 and x86.

At that point Firefox no longer loads tabs at all. About:<anything> doesn't work. Settings doesn't work. You can't go to safe mode (more on that later), and when closing the browser two processes remain taking about 60 seconds to end.

I did have the group policy templates for Firefox installed. When I upgraded to FF 91 I installed the latest templates.

A couple of times when I started FF it complained about vcruntime140 was missing. But just running FF again worked without doing anything else.

So I reverted to 78.15; I uninstalled v91.3esr. I deleted his profiles.ini and profiles folder and then copied them back from a back up. I removed any registry settings, and copied back the v78 ADML files. I then installed v78.15esr with internet disconnected. Did not run FF after install. Went into group policy editor and turned off telemetry and auto updates then re-enabled internet

Run FF and same issue. tabs not loading. Pages not loading. I can click on a menu and I can type into navbar and search bar but there is no response. I checked internet was working.

I deleted the %LOCALAPPDATA% cache folders. I flushed the DNS cache. None of this worked.

So I uninstalled FF again, deleted the profile folders and ini. Disconnected from Internet. Deleted any registry settings, and removed the group policy templates. Then installed 78.15 from scratch and let it create a new profile.

Same darn problem. It seems to me that installing chrome and/or edge has done something nasty, but I have no idea what. I say that because before he did that he could surf the web, but Netflix just said his browser ver was outdated.

I tried contacting netflix on chat but they were worse than useless.

So I uninstalled again and removed everything. Connected the internet and installed FF again and let it update automatically. Same problem.

I've left him with edge but I need to fix FF.

I even uninstalled the VCLibs, Chrome and Edge. These did not fix the problem.

I tried safe mode but when firefox restarts there are two processes that take 60+ seconds to end so FF sits there saying "restarting...". When those processes finally end Firefox does not restart.

Checked for viruses; nothing found. Rebooted PC several times.

So at this point in time; FF will run but will not load the 3 tabs; Facebook, Netflix and youtube. They stay blank. Settings is not accessable, nor is addon's or logins and passwords. Typing anything on the search bar does nothing Typing anything in the address bar does noting Trying about:config or about:profile or any other about's does nothing. When closing FF two processes take 60+ seconds to end.

If I go back to him and tell him I need to reinstall Windows he will go absolutely nuts.

What also worries me is that Netflix said that the most recent esr browser version was not supported and that he should update to a later version.

And what is even more troubling is I updated his girlfriends PC at the same time and hers works perfectly. This scares the hell out of me because I then expect responses like "Your sons problem is not a firefox problem".

I have been using Firefox 56.0.2 on Windows 7 for years safely. Until yesterday. We had one of those mini powerouts, that caused problems.

My hard drive is failing and Firefox will no longer fully load, it tries bless it, but some FF files must be in the damaged sectors of the hard drive. It then locks the system. Using Chrome works fine. But some logins/passwords/bookmarks had to be changed very recently and are not stored in the chrome browser yet. I hate chrome so use FF as the main browser.

I'm thinking that if I can install a fresh copy of FF 56.0.2 in a separate folder, a separate 2nd copy of FF, and then copy yesterday mornings backed up FF profile (before the crash) I could at least copy over all the bookmarks etc to Chrome so I can have my logins etc back.

This mornings backup failed to backup some FF files, all others were fine. Firefox worked fine yesterday but failed to launch this morning.

Please help save my sanity. I know I have to move to W 10, but cannot on this computer.

I am using Pop OS, which is based off of Ubuntu.

Somehow I did something, and it made the icon disappear for Firefox. I figured I could easily search the internet and find a simple solution.

I temporarily fixed it last night, but here it is missing again.

I could upload a picture, but I don't see what difference that would make. The dock at the bottom has a spot for firefox, but no icon, literally an empty spot, In the application menu it is a blank spot with Firefox worded underneath.

I have uninstalled, reinstalled, purged, deleted the application data in my user folder..

Just annoying. not a huge problem.

Yesterday when I installed the 96.0 update it has forced my background color into a dark grey and ignores the background color setting. I would like to know if there is a setting, add on or update that can return this to normal. The theme I am using has not been updated in 2 years so I am fairly sure the update has caused this.

After last update V104.0.2 fire fox will not allow me to access router to change settings message given, unable to connect, can I revert to previous version of firefox as always worked before update

I cannot find this anywhere. As a Topic . I've Reinstalled Firefox several times,and,each time the Browser continues to Import the previous instalations Bookmarks.

Noticed that a small Dialog box pops up stating what is being installed,with 'Importing Previous Bookmarks". Should be an Option on Instalation that handles exactly what is to be described as installed. Supposed there used to be. Since im used to installing w/o 'default settings.

The little check box that denotes 'use old settings,and apps,does nothing.

Have another problem with my Bookmarks. And this is what I need solved Reinstalling Firefox without Importing Previous Bookmarks.

Options for Migrations is not a punn here.

Question. How do I restore a profile from windows.old?

Details: Yesterday Windows 10 Failed (yet again , no surprise) Explorer.exe kept locking up and crashing at 1096 threads making it impossible to load/browse anything on my computer. After relogging into the OS I had about 1 minute to do anything before failure happened. (this while windows loads all the bloatware simultaneously which slows down access greatly) In short I could barely load/run mozbackup

Previously every time a windows OS failed I just restored firefox with mozbackup. Apparently that no longer works for firefox and has in fact been out of development for a decade. (tears flowing) The last time this happened ( 3 years ago like clockwork with any windows OS since XP) I moved both the profile folders to their respective locations from windows.old roaming/local to the roaming/mozilla and local mozilla folders respectively.

This no longer works and in fact causes firefox to not function at all. Since I need the passwords locked in firefox to access certain sites like hotmail.com and recover other things for my OS I am screwed. I have no Idea what idiotic concept cause the inability to manually port your profile but I need a workaround asap.

I cannot even log into mozilla.org properly without it either and was forced to use a gmail account just to post this

HELP!!!!

So yesterday I got a new computer and downloaded Firefox to be my default browser. It worked fine the first few hours -- I was able to log into my account, set up my extensions, and use the browser as intended. A few hours in, though, it completely crashed on me. I am unable to go to new websites, refresh a page, open bookmarks, log in to my Firefox account, or even open settings; the home screen also doesn't load when I open a new tab. Literally the only thing I can do is freeze the Bookmarks Toolbar and customize the Toolbar. I tried closing and reopening, refreshing/resetting the browser, restarting my computer, going into Troubleshoot mode, deleting and redownloading the application, but nothing is working. I have no trouble with Firefox on my previous computer or my phone, and Edge is working fine on this computer. I don't know what to do anymore. Any help would be much appreciated.

Hi!

When Firefox 96.0 rolled out on my machine, I was surprised to see my old Firefox Quantum theme default to dark. I did not enjoy this new behavior, so I tried to downgrade to 95.0.2. After installing it, Firefox told me it couldn't load the user profile, as it was used on a newer version of Firefox.

I have no idea where exactly I read this, but some website contained an instruction to erase compatibility.ini and that would allow me to use the profile on older versions. Tried that and it actually worked. I did notice that, when Firefox tried to update, it would say it failed. I was hoping that, once I find a solution to the forced dark mode and I update Firefox, the problem would go away.

Fast forward a few weeks, I found AutoConfig and browser.theme.toolbar-theme option in about:config. So I updated Firefox manually and applied AutoConfig and my original problem was gone.

Fast forward more weeks, there is another update for Firefox. And Firefox was still unable to automatically update. So I tried reconstructing compatibility.ini, which I did fully. But Firefox still won't update.

At this point, it's been like 3 months with a crippled user profile and I must say I'm tired of updating Firefox manually.

Is there any way I can fix this profile? If not, what exactly should I copy over so all my preferences, cookies, addons and themes get carried over to a new one?

Hello,

I've set up Firefox to ask before updating, so I was taken aback by the fact that today, an update was automatically installed without Firefox asking me... (I was updated from 97.x to 98.0)

It is especially frustrating, as the mandatory "Restart" screen is broken when using several profiles, at least under Debian.

Let me know if you need more information.

Best regards,

Adonis
