Firefox 技術支援討論區

I just reinstalled my operative system, and with that my Firefox settings got reset. I know there is an entry in about:config to prevent ads from opening new tabs and pop ups without authorization, even from legit websites like the login pop-up windows when doing a sign in in Google, in those cases to allow the windows it's needed to click on the lock icon next to the URL bar and allow it from there. The problem is that I don't remember the name of that setting and I have spend an hour looking for it on Google.

Hello,

I'm using Firefox 91.4.1esr (64-bit) from Debian repositories on Bullseye. Every time I open Firefox, a window with a greeting message appears ("Say hello to a new Firefox"), and it doesn't matter if, as asked by that window, I choose a theme or not. Is this issue related to my settings? Is this a Debian issue? Is it possible to stop that window from reappearing?

Thanks in advance. And many thanks for making Firefox (I've been using it for so many years I can't recall when I tried it for the first time).

How to allow web page to override a keyboard shortcut. Currently firefox picks up the shortcut instead of the webpage...

For example I have an webpage that detects ctrl-shift-h which worked fine in version 56 but now in version 96 it brings up a "Show All History" dialog

I an doing many such things so I looking for a generic way to override firefox keyboard shortcuts

~~~SOLVED~~~ Hello guys, this is about some..adults sites, i'm just getting loading error on the screen. Sorry if that's inappropriate. Also recently, youtube videos can't play at 1080p, only 720p, even tho i know the video it's 1080p.

Many file types are no longer listed under Settings > Applications>Content Type at about:preferences#general. I used to be able to click on a file in an email like a Word or Excel document, and it would come up on my screen. Now Firefox asks me to Save them. I don't want to automatically save files without first looking at them. How can I get those file types in the Application list again?

I have attached a pic of the file types I have left to chose from. There used to be a lot more. How can I get back all the missing choices I have had there for years?

I'm hiding menu items using userChrome.css with option “toolkit.legacyUserProfileCustomizations.stylesheets” set to “true”.

So I am hiding some menu items like for example

1. menu_find { display: none !important }

however though the menu item is gone how do I get rid of the ctrl-F menu shortcut...

I have many such menu items to remove so I need a generic solution to override the short-cut icons associated with the menu items I want to remove

When I am not in full screen the minimize, maximize and close options are there. They disappear when I go into full screen and I am forced to get out of full screen to minimize or close firefox. This only started happening recently. Does anybody know how to make these options appear again while in full screen?

When Firefox asks if I want to download an update and I agree, soon after that but not right away it stops working - on every new page it says "We need to restart to finish updating" <- This last bit is VERY annoying. Is there a way to keep FF working in such situation? I usually have 3 FF profiles running, about 10-20 tabs each and when it suddenly does this - I can restart them all but when it is suitable for me.

The only solution I can see so far is disabling updates via group policies (which is not well documented, where do i put this policies.json on Fedora? need to google that).

Any other ways to keep updates and FF running until I decide when to restart? Thanks.

I want to be able to print my .docx files without saving them first. I went to General and Applications. .docx is not in the list, so I'm unable to select how it handles these files. How do I add .docx to the list of content types?

When I am watching a TV stream on my PC; when I hover on (some) pictures or videos, a supremely annoying pop-up url appears at the bottom of my screen. I have some learning problems and can not figure out the 'userChrome.css' method. I can not work with long streams of multiple overlapping instruction. I am not tech savvy. I do not understand 'layers' and stuff like that. I can do the 'about:config' thing, if anyone knows whether or not if I can fix it from there, I would be eternally grateful. Thanks.

my bookmark star has disappeared from the search bar ( along with the little page icon for the more friendly reader version) weirdly when I opened this help page it is present again, but then when I try to reopen another tab it's gone again

been looking for a remedy can't find one that recent doesn't talk about the 3 little dots in the search bar

I attempted to install a router but Mozilla sent a caution message that the brand (Net Gear) was insecure. Which brands are secure routers?>I have a Mac Book Air purchased a few months ago and have never had internet at home. This is first attempt. Thanks.

I recently upgraded my system and, after installing and using Firefox, I notice the Find (Ctrl + F) bar is now at the bottom of the window. Whereas, it was previously at the top (which is more like every other application I use).

After some head scratching and web searches, I remembered I had to fix this issue previously (after a Firefox upgrade some time back). The method to fix it then could be found here: [there a way to put the Find Bar at top] That link is of course to the same question asked 4 years back.

I have once again followed the procedure there explained per: • Access my Firefox profile folder. In my case:

  C:\Users\<Me>\AppData\Roaming\Mozilla\Firefox\Profiles\5ym42ewi.default

• Create folder therein called ‘chrome’ • In that folder create a file called ‘userChrome.css’ • In that file add text:

  .browserContainer > findbar {
    -moz-box-ordinal-group: 0;
  }

However, after doing that (and restarting Firefox), the Find bar stubbornly remains glued to the bottom of the window.

Can anyone tell me how to solve this issue?

As a separate note to the developers: This issue is long-standing, that a web search reveals is still relevant to many users. Any chance of considering making it a standard option?

I had a number of tabs open today (~40). Because Firefox started to malfunction, I had to restart Firefox. It happened to me before and I knew that I can restore my previous session so I safely closed the tabs.

When I restarted it, I opened a tab and then I tried to open the Application Menu, but accidentally closed the window. Now, when I've re-opened Firefox and attempted to restore the previous session only that last tab appeared.

Is it possible to recover the pre-previous session? I use Ubuntu 18.04. Where is this information located? and how can I retrieve it?

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.
