Firefox 技術支援討論區

A few weeks ago I saw an Mozilla ad for a new Mozilla software product that cleaned up your PC and made it run better. The price was around $125.00 (I don't remember that exact price). It said that I would receive an email from Mozilla with download instructions. it's been a few weeks and I have not gotten any email. Does anyone know if Mozilla offers any such software or did I get scammed? I'm pretty good about seeing scams but Ive used Firefox and Mozilla for years and trust them. Maybe that's why I wasn't as careful as I should have been.

Thanks for any help that you can provide. Ron

When I download PDFs on my MacBook using Firefox (currently 124.0.2 (64-bit)), they are always blank - I have attached a screen shot.

But if I download the same PDF using Safari, it opens straightaway - 2nd screen shot.

Is there something I need to adjust in Firefox to allow PDFs to open?

When I attempt to login it just spins and nothing happens. Works on Safari and Chrome.

Opening DevTools I can see an error about "CORS Missing Allow Origin" but I don't have this issue with any other browser. I have disabled/removed all my browser add-ons and the issue persists. I have no problems logging in to any other site.

For some reason, in my firefox profile, when I try to access "https://accounts.google.com", it open on new tab with a specific container, while other url keep open with no container. I've never configure this behavior, or found a setting to fix it. It only happen on my current firefox profile. If I create new profile, this problem didnt occurs.

I have migrated from old MacPro to new Mac Studio. Firefox ESR version 115.9 has migrated with it. I've downloaded the latest Firefox but it operates independently of the ESR version. How do I ensure new version has all log in, contacts and history?

On my Windows-11 Laptop, the Vertical-Scroll-Bars in Firefox are too narrow for me to use comfortably. I am struggling with the Touch-Pad, Mouse Pointers, causing the frequently needed act of Scrolling to become a dreaded ordeal? If someone would provide clear and concise instruction on how to make the Vertical-Scroll-Bars the Classic Width of old, it would be greatly appreciated. Thank you! lg

My Firefox Browser on (Windows 11) updated on 23rd March 2024. Now my History and Bookmarks have been deleted (but not cookies for some reason). yes, it is my correct profile as I checked the dates and also double checked it against a backup I made 2 weeks ago.

Have included an image of my 'more troubleshooting information' details - I'm sure this is supposed to have more data on the page?

If there is no way to recover my hisotry and bookmarks, I see there in my profile folder is a 'bookmarksbackup' folder which contains .jsonlz4 files, one of which was saved on the 21st March 2024. I know book marks are .json files, can anyone tell me how to turn a .jsonlz4 file to a .json?

[Oh, I pressed to add here my 'troubleshooting information' as directed by this forum page and it said it couldn't automatically do it, and when I pressed 'manual', it opened that over this page and so when I pressed 'back' it had naturally deleted this post so I've had to retype everything from memory, thanks so much Mozilla for that. How about a warning that this will happen?]

My home screen and all other browsing screens are so high and wide that I can't scroll down because the side slide bar is not on the screen. I have no idea how this happened! I can't find any articles that help me reduce the screen size that I can understand. There seems to be no solution option in firefox settings to adjust the screen size. The View tab does not help because it just offers zooming of the data on the screen, not the actual size of the screen.

When I try to detach a tab, so that it's a new window, by dragging the tab downward so it isn't on the tab bar. After I let go a new window is created for that tab that I dragged, however it also maximizes the window, which disorients my work flow. Is there any way I can detach a tab into a new window and not have it maximized automatically?

Fiz a configuração para sempre perguntar onde salvar arquivos nas configurações, em aplicativos em "Tipo de Conteúdo" selecionei o PDF para "sempre perguntar". Acontece que quando seleciono para abrir o documento pelo adobe ou pelo firefox, ele está está salvando na pasta Downloads automaticamente, e eu não quero que salve. O meu Firefox está atualizado na versão 124.0.1. Windows 10 Pro 22H2. Meu Firefox está salvando os arquivos PDF na pasta Download mesmo eu não querendo salva-los. só quero visualizar. Enviei imagem da minha configuração.

Obrigada

I am facing issue while downloading files in Firefox Private Browsing. Whenever I download my PDF files, as soon as I close the browser window, the files also get deleted automatically. What should I do to rectify this issue.

I want to use a key to open Speed dials in the same tab and same key with 'Shift' to open that speed dial in a new tab.

My favourite were Ctrl+1, 2, 3, 4 ... and so on. And when I used Ctrl+Shift+1, 2, 3 etc, then they opened in a new tab. But now the Ctrl+1, 2, etc are focusing already open tabs. How to revert to old behavior of these shortcut keys?

I've read several articles on using extensions like 'Shortkeys (Custom Keyboard Shortcuts)', but those don't let me use C+1, 2, etc. Also another method of using to js files (auto.js something) doesn't seem to do this job, as I think that would only disable some KeySrtcs altogether.

Firefox takes a very long time to open the first tab. After it opens, subsequent tabs open relatively quickly. I've tried self help suggestions like clearing cookies, cache and history, updating, even removing home page content. Nothing helps. It's getting intolerable and I end up switching to other browsers rather than sit and wait. Starting to even dread using firefox. Running Sonama 14.3.1 on my iMac. What else can I do?

see my screenshot: 1. this smal ? arrow - show tab titles- how can i disable in about:config 2.other symbol -extensies are empty...how can i add here my addons? 1- i dont have it in my desktop and 2-in this desktop i see all my addons, in this symbol.these screenshot are from my new laptop...

When editing in Gmail, holding a key down does NOT repeat the character or action. e.g. xxxxx when holding down the "x" or deleting multiple characters when holding down the <Backspace> key.

It works properly in other apps (e.g. this dialogue).

And works okay in Gmail in other browsers (e.g. Chromium or Brave).

I'm using Firefox 124 on Linux Mint 20.1.

System: Kernel: 5.4.0-174-generic x86_64 bits: 64 compiler: gcc v: 9.4.0

          Desktop: Cinnamon 5.2.7 wm: muffin dm: LightDM Distro: Linux Mint 20.3 Una 
          base: Ubuntu 20.04 focal

I use Firefox in French... but lately, the contextual menu when right-clicking on a web page shows in English. The contextual menu when right-clicking on the Menu bar or Bookmarks toolbar, is partly in French, but with a section in English (the Menu bar)... sometimes, the Menu bar switches to English (I can't seem to isolate what makes it switch or switch back). Other menus show in French and setting for language is set to French.

Is there something I can do to fix this?

Firefox 124.0.1 (64 bits) on Windows 11

I have Firefox on 3 devices, I deleted several passwords from 1 device expecting this change to sync to the other 2 devices. Instead for several days the 2 devices showed the original number of passwords whilst the device I made the changes on showed the new amount. Now that device appears to have resynced the passwords I deleted. Am I supposed to delete them on each device?

I have the latest version of FF on all devices.

Hello Ladies and Gentlemen!

Please read my post completely before answering! Thank you!

I'm using

• Firefox DevEd (manually installed) as my primary driver and
• the standard Firefox (installed from the package manager) for leisure/hobby related browsing

each with its own Mozilla account and profile, on Manjaro KDE. Sadly, either Firefox sees all the profiles. They have usually different versions. If I mistakenly start one of the Foxes in the other Fox's profile, the newer version of Firefox (usually Firefox DevEd) autostarts migrating that profile. Which it renders the profile "corrupted" for its intended Firefox.

I'd like to have Firefox DevEd unable to see profiles (or anything else) intended for the standard Firefox and vice versa. Or at least unable to botch profiles. I do not want to disable migration or use no. Given that Firefox configuration location is hard-coded, I'm not having high hopes for my wish.

I'm wondering if there is a way to keep two Firefox installations completely isolated, other than running them in containers.

Thank you for your time!

Hi. I was just looking at Google Photos on both Firefox and Chrome. Chrome had a bigger picture because the window had only the tabs bar and the address bar, and Firefox has an additional title bar. I was wondering if it would be possible to remove the title bar so the picture on both browsers were the same size?
