Firefox 技術支援討論區

Hello,

I've used Firefox for many years. Long story short I have a new computer and was looking to keep my passwords bookmarks etc. so I looked up how to find them and saved the two folders to an external HD before my old computer was wiped. In trying to get them imported into Firefox on my new computer I thought I'd just erase the ones in the current folder and replace them with the other files. Well that didn't work. Now Firefox won't load as it says it can't find my profile. So I erased Firefox and tried to reinstall but it still won't open and says it can't find the profile even after I erased and reinstalled. I understand the problem I caused but not how to start fresh and import my old settings. Any help would be greatly appreciated.

Cheers,

-rob

Hello, My firefox has been randomly exiting for a longer time now. (I reopen Firefox it restores itself without any crash info) I've already tried reinstalling and using the cleaning tool. Now I wanted to remove my Addons, but one of them isn't deletable. It also has no name displayed which confused me... Furthermore, there are only "InstalTime12345678"-files in the crash reports directory (which I think aren crash reports). It seems to me the mysterious addon is installed through the policies. (I have a screenshot attached and uploaded them https://pastebin.com/59wzMDyv) This is my private computer and I never set those. Has anyone seen this before or can help? Thanks

Dear Sir or Madam,

I'm running 101.0.1 and spell check no longer works on any mail app like Gmail, Outlook, Yahoo, BT Mail. If I use Chrome or Edge then spell check works correctly. This is despite my Firefox Settings being as below.....

Language Choose the languages used to display menus, messages, and notifications from Firefox. ENGLISH GB Set Alternatives… ENGLISH GB Choose your preferred language for displaying pages. Choose… ENGLISH (United Kingdom) (en-gb) Check your spelling as you type = Tick (Yes)

Could you please advise a fix?

Kind regards,

Neil.

P.S. If I use Chrome or Edge then spell check works correctly.

I want to select multiple Tabs from a bookmark folder to open in the background.

On Chrome this used to be quite easy: Just open the Dropdown, click whichever tabs you wanted to open with the Mousewheel and done.

On Firefox you need to enable new tabs to open in Background first. I managed to find the setting for that with google after a while. You need to go to advanced settings by typing about:config into your url bar.

Then you search for browser.tabs.loadBookmarksInBackground and click "enable".

But this didn't fix the other issue I had, that the dropdown menu always closes as soon as I click anything.

Is there a way so it stays open until I'm done selecting the pages I want?

How do I create a TLS 1.0, 1.1 exception in Firefox 100.0+ for my legacy devices (NAS), that no longer get firmware updates from the manufacture, that are on my private network and thier configuration is done through a web browser?

 I have been using Firefox browser for a long time, since it was called Mozilla browser.  An answer such as "I'm out of luck." means I will have to look for a new browser.  I prefer not to do that.  I trust the Mozilla brand and like you products and recommend them to my friends and customers.

Audio was working fine until recently. Now, firefox has no audio playing on any site.

Some sites show "PLAYING" in tab, but others like YouTube don't show that notification. Even with "PLAYING", there is no audio output.

I checked Windows settings and Firefox is set up correct (and the same as it was before it stopped working), see screenshot attached. Otherwise, I restarted Firefox, tried it in troubleshoot mode, and reinstalled Firefox. No changes.

Possible system changes include: Maybe a Firefox update occured and broke the program? I installed the game Civ5 from Steam which required some Windows VS redistributibles installed.

I am reinstalling Windows\Firefox, and would like to hide\remove Bookmarks Toolbar & Other Bookmarks, as shown on the images. The Delete Folder option is greyed out for both, and Other Bookmarks is empty.

Both were hidden\removed in my original installation, but I can't remember how I did that. I've seen posts mentioning e.g. browser.toolbars.bookmarks.2h2020 (it doesn't exist) in About:config, right-clicking on the Other Bookmarks and uncheck it (it doesn't exist).

I'm using Firefox 101.0.1 (64 bit).

In settings, Start-up, I have the box checked for: "open previous windows and tabs" but it doesn't work. In order to do my work I need the 23 tabs I currently have open to show up again after a reboot of the browser or computer. What gives? How long will it take to get this corrected? Please give me help. Thanks, Mark

I've tried everything and read all the instructions but none work.

For some reason, whenever I load a pdf from within Firefox, I get a new tab with the regular toolbar displayed on top of pdf files, but the document itself is completely blank (see attached screenshot). This issue just started today and I assume it was a result of an update, since I don't recall making any changes to my settings (I'm using Firefox 101.0.1 on Ubuntu 20.04).

I've tried opening multiple files from a variety of sites with the same result. All of them open fine using my system's pdf viewer, as well as from within Chromium. I've tried disabling my plugins, putting Firefox into safe mode and resetting all the handlers, to no avail. Any help would be much appreciated.

Firefox allow to disable access to canvas for lowering fingerprinting, it's cool !

But as web developer : i like to ask this access before try to using it,

Something like :

1. Do you alllow canvas ? 2. Show the browser part 3. Wait for user answer 4. It's OK : download PDF done with canvass 5. It's not OK : shown an error to user.

To avoid such situation (see screencast)

The latest update for Wondows 10 prevents Firefox (and Edge) from loading. Everything works fine once I've uninstalled the latest update so the problem is clearly theirs. I can't be the only person experiencing this problem but contacting Microsoft is next to impossible. I wonder if you can: 1) alert them to this issue; and 2) pressure them to fix it as constantly uninstalling the updates is a pain!

Lately I refreshed Firefox so I can boost it's performance cause it was running just a little bit slower than usual. Since than YouTube does not remember my selected resolution. Every time I close the tab, in the new tab it will have a much worse resolution and I did not have a problem until now. I am a system administrator and I'm currently learning programming as well, so I tried a lot of things to try to overcome this problem. The only extensions I have is Bitwarden, uBlock Origin, Cookie AutoDelete. And yes, youtube.com and *.google.com IS added to cookie AutoDelete. But even without it it's not working.

I have provided the Troubleshooting Information from about:support: Click Here for Troubleshooting Info

I also know that there are extensions like YouTube HD or Enhancer for YouTube what would solve this problem, but I would like to keep my extensions as minimal as possible.

Thank you!

I have tried all of the suggested solutions here at Mozilla for how to delete a website URL from being autofilled: whenever I type 'pre', the autofill function fills in the rest of the website 'www.preply.com'. It was a horrible ESL teaching scam website, I only taught through it for a month last November then quit when they ripped me off. But now since last November, any time I type in 'pre'–I invariably see their annoying, shitty website :-( It is very annoying because it was a bad employer experience–and now I cannot ever remove them from Firefox :-(

I tried deleting it in the address bar with shift + delete, then also went into some obscure Firefox folder and deleted some file with Firefox closed (this was the supposed "solution"–it did NOT work).

Is there any way to solve this incredibly annoying issue? Or should I just switch to Chrome or Safari and give up? Very disappointed in how impossible Firefox makes deleting autofill URLS, really, REALLY BAD software programming. Any helpful or solution greatly appreciated thx :-)

Using Mac OS 12.4 and Firefox 101.0.1. After launching Firefox, a second icon appears in the "recently used" apps section of the Mac OS dock (see attached screen shot). The icon stays there and goes away, and then comes back, and then goes away, etc. This continues on and on until Firefox is closed.

Why is this happening? Never acted this way before the latest updates.

A website MultiSafepay.com has saved my CVV number in Firefox.

How do I edit the autofill data?

I can't get to the same payment page, to be in a position to delete it.

Most links on this matter refer to:

 Options => Privacy & Security => Forms and Autofill

However in my Version: Firefox 98.0.1 (64 bit) running on an up to date Windows 10 this feature is missing or deprecated.

Can anyone say how I could edit/delete this specific entry, or point me in the direction of where this data is stored?

In the mean time I can't recommend using Firefox for entering critical security data, where websites can allow the storage of CVV numbers.

Since the latest update of Firefox, I now notice that each time I download anything the downloads icon in the toolbar expands the download history and remains in front of the browsing window until I click out of it. This behavior is reminiscent of the Chrome browser opening a pop-up bar every time I download anything which had to be manually closed — a regular irritant. I can see where some may prefer to have the pop ups, but I don't appreciate it becoming the default. Is there any way to disable this behavior so that it downloads in the background as it used to?
