Firefox 技術支援討論區

I'm currently developing a website that use user printer. And I'm looking for a hook that I can use to know user click the confirm or cancel in print dialog(or print preview window). the onafterprint method will trigger before user click confirm so I guess it's not an option.

Also, someone please tell me the topic describes my questions, I really don't know which topic is best for my question.

hello! i'm looking for a way to adjust the settings, if there are any, to copy and paste PNG images with firefox and keep their transparency intact -- rather than the solid black it has now. as i understand it there's been similar issues as of 8 months ago, but i'm unsure if anything else has changed in that time.

i'm not a full-on graphic designer or anything but i do use this fairly often as an artist to look at references and such, and as someone who's recently switched to firefox from chrome (which does support this feature) i'd like to know if it's as easy as clicking something in a menu or if that's not an option altogether. thank you in advance to anyone willing to help!

After the last couple of updates Firefox will not wrap words in view source screen(CTRL+U). This makes the info very difficult to read as most lines of code run off the screen. How do fix this? Thanks.

I selected "Tips and Tricks" because I always feel like everyone seems to understand the answers and I do NOT.

I have and donated to Firefox since it began. I think it is a great idea. I have severe dyslexia and ADHD.

I keep add-ons to a minimum and my home page free of everything. I use menus to find what I need. Having short-cuts all over is too distracting. When FF is not available and have to use another browser, I find it very difficult: they are loud, busy and ads are all over.

I am finding "help" more and more difficult to understand. Do the folks realize that I don't use computers all day long? That some people don't use the same definitions as people who work with computers? (I tried to find the meaning of "default" with 0 results, phrased the question many ways.)

I am hoping a beginners guide review would help, as thing have changed since Firefox was new or "Firefox for Dummies" was written!

Is is/are there basic manuals? Please help. ("Please don't respond with what help are you looking for" - that will not help the next problem).

my hardware is very outdated already and i wanna try if my firefox runs better without any hardware acceleration like running fully on software.

i don't think that just simply disabling the hardware acceleration in the settings disables the entire hardware acceleration because there are way more about:config preferences which are related to hardware acceleration.

Firefox is pissing me off. I want to disable SSL security checks long enough to do what needs doing. I'm working from a container so there's really no risk, just need the browser to do what I want not what 'It' wants.

Hello, I've got two profiles, 'Home' and 'Work'. I run two Firefox windows with these profiles. Now, I want to open a link from another application, like Slack or terminal, and want it to be opened in some predictable Firefox window. Now it depends, probably, on which Firefox window I opened last. So I want to be able to select in which window the links should be opened: I see it as marking a window as the default one. Note, that I don't want to set a default account, as there's no default account for me, I always choose which account to use when opening Firefox.

Thanks.

the preference "browser.contentblocking.category" does still work although it isn't existing in the about:config settings anymore(was removed as it seems) but how and why does it still work?

on some websites it says -1 tells Firefox to automatically determine the size of the cache based on your physical disk and setting it to 0 would effectively disable any disk cache entrys.

so are this informations true and if not, how do i still let firefox automatically determine the size of the cache based on my physical disk?

i'm currently writing my own firefox user.js configuration and now i'm at the topic "unloading inactive tabs" like microsoft edge does.

so what are the preferences for this kind of topic?

i want inactive tabs which have not been used for more than 5 minutes to be unloaded.

chatgpt gave me this "browser.tabs.unloadAfterDelay" preference but this one doesn't even exist in the about:config preferenes, would it still work if it doesn't even exist?

I backup my Firefox profile on G. Drive (encrypted). It takes HOURS to copy the whole profile folder (bad internet). When I copy the updated folder into the old one, should I ignore the old files or overwrite them (and take hours in the process). There is a chance that my backup fails because there are too many old files that I ignored and left there?

The topic says it all. How do I prevent Firefox from shifting my typing from the search field to the address bar?

I try to type a search into the field on my homepage but the cursor gets shunted up to the address bar and I can't find a setting turn it off. I would prefer my typing to stay where I place the cursor with a click rather than being shunted off somewhere else on the screen.

Say, for example, I want the download path to be "MyDownloadDirectory/%yyyy/%yyyy.%mm" which means "Change the download path every month to a folder named after the current year and the current month inside a folder named after the current year".

Many non-browser applications allow me to do this, but for some reason browsers generally don't have that option. I was thinking that there was a way to do this in Firefox.

What is a way to do this? If it's not possible in vanilla Firefox, is there an extension available for this?

Hello,

I upgraded my FireFox to the latest version 88.0 today, and noticed some changes on right click menu. In the old version, the keyboard shortcut key is a to copy a link, but now it was changed to L. That is really inconvenient. As you know, when you right click a link using the mouse, your right hand is still holding the mouse, and not easy to press the letter L on the keyboard.

The old menu option is "Copy Link Locaton", but the new one is "Copy Link".

Is it possible to customize the keyboard shortcut of right click menu, please?

Thank you! Brian

Hi, I'm looking for some creative solutions to be able to search for Bookmark Folders imported from other browsers. I have over thirteen thousand bookmarks and I have used some extensions to delete the duplicates. However, that has left many empty folders and worse where my Bookmarks have been removed from these folders.

With Chromium browsers, we can simply search for a Bookmark folder by typing it's name. It will show itself in the search results along with Chrome bookmarks. However, that's not the case with FF. Instead, FF allows us to create TAGS. When I search for a known Bookmark Folder (I can see it in the Bookmark Tree) it won't show up.

it's almost 2024 and I find it surprising that Mozilla hasn't yet incorporated searching for Bookmark Folders. At the same time, I am also (not) surprised that Google hasn't implemented TAGS like in Firefox. Unfortunately, neither browser is ideal for searching bookmarks including folders.

Perhaps I'm missing something and there's a feature in the About:config that allows us to search for Bookmark folders.
