Firefox 技術支援討論區

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.

Hello Friends,

I installed the new Firefox Update, but I'm very unhappy with that. Because the Download Panel disturbs when I do many little Downloads and it is Shows every time. Is there any Chance to change that?

The second Problem I have is that I Download "dlc" Files and I want to Open them automatically in jDownloader, but the Option with "Always Open Similar Files" don't exist in the Download Panel so I can't say it should be opened with jDownloader. Is there any trick to get unknown Filetypes opened with a Program? With the Version before this it works without any problem.

Greetings René

On 30 August 2023, when opening Mozilla the second time in a day, a pop up window emerged asking whether I allow Mozilla to make changes on my hard drive (or: hardware - I cannot remember now) due to the updates.

I clicked yes, as otherwise Mozilla would not work, then an opening site appeared about the new features of the update, and talking about the possibility of the VPN service.

It seems that now I am working on the latest version of Mozilla released first on 29 August 2023 - 117.0. When checking in the settings, the date of the installation was also 29 August and not 30 August. This made me puzzled, why I got this pop out window only on 30th, and in addition only after the second usage of the browser (however, when checking in my comp settings, the update of Mozilla is dated 30 August 2023)... In addition, as never before I have seen Mozilla asking for making hard drive changes, I got worried whether it was not a kind of virus or other malware pretending to be Mozilla.

Could you please confirm whether the pop-out window asking for the changes to hard drive was indeed just Mozilla asking for valid changes? I am very worried I got a malware on my computer, although the antivirus scan does not show anything.

I have asked some friends and they had the actualization automatically done without this pop-out window.

I have checked some online discussions and verified in the properties that Mozilla is NOT allowed to run as administrator. Also, the "Run this program in compatibility mode for:" was also unchecked.

Thank you in advance for your answer!

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.

I am following all the instructions. It has continued to fail for the past year. I've uninstalled ff and reinstalled ff. I've tried creating new profiles. I can import everything into Chrome or from Chrome to MSE, but NOTHING will import into ff from any other browser.

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 :) For some time now my firefox doesn't allow me to preview PDFs. If I open it, it gets downloaded at the same time which I don't need. I already tried the thing with renaming the handlers.json to handlersOLD.json but it didn't work :( does anyone know how to fix this?

Hi,

For work reason, I need to use specifically Firefox version 68.3. Unfortunately, I couldn't use it on my Mac M1 (Ventura 13) as it always crashes and refuses to open.. Please anyone can help me with this? Thank you!

When I updated to Ff 118.0.2 on Ubuntu 22.04.3 LTS today 4 out of 7 windows disappeared. When I upgarded Ubuntu from 21.something four days ago 6 out of 9 windows disappeared. Can I get them back or do I have to stop upgrading?

Is there an easy way to downgrade back from the beta channel to stable? The downgrade protection feature seems to be a major blocker of just installing the latest stable version. Noticing high RAM usage on Firefox 100 and crashes which is making it hard to use for a daily web browser.

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!!!!

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

I cannot download Firefox for desktop. I get an error message in my Chrome browser saying my connection is not private. It says my certificate is not valid.

Where do I go from here?

Thanks, Denny

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.

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

The Firefox on my PC abruptly stopped working for pretty much no discernable reason and I don't know what to do. I've tried restarting the PC, uninstalling and reinstalling Firefox and nothing.

I dont get an error message. It just...doesn't start. If I reinstall it, I'm able to get the browser pulled up but then nothing on it works. It won't take me to any websites, it won't open the settings, it won't do anything. Refreshing the browser doesn't work either.

Failing that, I hopped on my phone and attempted to troubleshoot using information on this very site. I discovered that the problem might be stemming from corrupted profile data. I attempted to load the profile manager from Windows using command prompts...but that command doesn't do anything either.

I attempted to find the profile data on my computer and delete it...didn't work. I tried to reinstall Firefox to have it generate new browser data and that didn't work either. I dont know what to do and I dont know I'm supposed to fix this.

Please help, thank you in advance.

The update Firefox 100.0.1 ( or 2 ) has a bug: Firefox doesn't "see" the Fritz!Powerline ( LAN over Powerline adaptors ) and thus I can't enter the Fritz!Box. Even typing the IP address of the Fritz!Box doesn't help, because there is "no connecting" beyond the PC. The hardware works, so I can send and receive emails, but I can't access the internet via the firfox browser. Stepping back to 99.0.1, I had to "create a new profile" and all my previous ( before the update to 100.0.1 ) settings were lost, all bookmarks vanished ... I am rather angry, you know? This mail I'm sending via my notebook, as I this connects via 100 Mbit Lan network from an other room and as I had to "register" just to be able to complain ...

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.

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
