Firefox 技術支援討論區

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 have used Firefox for years. I am computer literate and do not like the newer approach Firefox has taken to save all downloads to my downloads folder. I have to continually go in and manually delete the files.

For instance, I have a lot of pdf forms that I have to open directly in Acrobat, those files are then duplicated and saved in my downloads. This is causing a mess for me.

This was NOT an improvement in my opinion. Is there a way to stop this???

I have recently set Outlook Mail to send desktop notifications when email is received. This works when the setting is on. However I have noticed twice in 3 days the setting has been turned off- but not by me! This is unacceptable. I would be grateful if you can advise me of anything I can do to ensure that when I change a setting/preference in FF that it stays changed until I select a different setting myself. In the case of email it is important as may miss something important. Thank you,

A Client recently dumped their Windows server. They ran IIS and had an Intranet website. The website has been static for years and I have set up a method for the tech person there to propagate changes without having to visit each PC, should the need arise.

The browsers were all running NewTabHomepage so that when a new tab was opened the homepage from the website was displayed. They do not want an external website as their homepage as the internal one has links to a bunch of stuff they use all day.

When the homepage in Firefox is set to open a page via file:/// rather than http:// when a new tab is opened the homepage is not loaded. A blank page is displayed.

Is there a way around this?

When watching videos on streaming services (e.g. Netflix) a "1.0" is placed in the center of the screen. How do I get rid of it? (I don't want it ANYWHERE on my screen.) Thank you for your help.

I hope this applies here. I tried using the "-p" command fro Librewolf. Wiped out my sessions and settings.

Is there a way to do this in Firefox and or Librewolf?

Issue 1: When I open up the firefox settings, I cannot tell in the slightest what is and isn't checked off because nothing appears in the checkboxes. They're just empty squares regardless of whether something is checked off or not. I've attached a screenshot below.

Issue 2: I really, really hate the new proton tabs. I had them disabled by disabling proton, but I guess I forgot to disable auto-updates, because I just opened Firefox to find that they're back, much to my displeasure. It's difficult for me to distinguish tabs from each other at a glance now as they are all the same color with no borders *and* having 'autoplay disabled' and 'playing' and stuff like that in TINY all caps font below the tab label is NOT USEFUL. It is distracting to the eye, and I have to squint and lean closer to be able to read what the heck it's even saying. This is shitty for nearsighted people like me. Moreover, at a glance it is IMPOSSIBLE now to tell which tab sound is coming from. This is a huge step backwards in functionality and accessibility.

I wasn't using mozilla for aesthetics - I was using it because it functioned and was more stable / less of a memory hog in my experience than chrome, and I appreciated the ease and convenience of syncing across different computers as well as the built in password management. However, I question whether I can continue to use this browser if you're going to prioritize aesthetics over functionality and user preference.

Seriously - that the tabs DO NOT CONNECT to the page is itself distracting and weird, *but also* that the rest of the tabs blend together and have extra tiny unreadable text rather than the infinitely more distinguishable audio symbol that indicated which tabs had sound playing before is so terrible.

So.... tl;dr: HOW DO I GET OLD TABS BACK?

I have no screen capture whatsoever - no menu comes up with a right click, no screen capture icon is present to add to the menu. I used to have an add on but that disappeared and is no longer available. From your latest tips letter I think I'm using a different browser entirely! If you can help I'd appreciate it- as I say I used to have it in my browser but no longer. Now I have to screen capture and edit it in an external program- I'm sure you'll agree this is horrific to have to do.

I just got my upgrade from Firefox86 to Firefox90 working, but the tab bar is completely missing.

I still use "old-style" FIrefox. From top to bottom: File/Edit/View menu Search bar Bookmarks Toolbar Tab bar

(yes, I AM old. I've been using Firefox since Version 1 and this particular style works for me, developers be damned.)

The tab bar is completely missing. Firefox knows how many tabs I have open (it warns me when I try to exit) but doesn't show any. The area that the Tab Bar used to occupy is simply empty.

Any ideas on how to fix? (Yes, I have done the Google.)

I have been unable to figure out how I've managed to make my addons no work properly.

I've tried running them in debug mode, but I'm not particularly adept in debugging addons.

I've reset Firefox back to default a few times, addons seem okay, and then as soon as my Firefox account syncs and installs my installed addons they go back to wonky.

I can't seem to attach images RN, Firefox (Nightly) crashes every time I click on the button.

The behavior can be described as the addons when clicked have a blank page as their contents, and some addons (Like Dark Reader) just have like a sliver of a drop down with no contents.

If you'd like me to grab some debug data from wherever just let me know.

As of recently, Firefox adapts some elements (basically everything in the toolbar, like the downloads or browsing history) depending on whether it identifies the theme you use as light or dark. I am using a custom theme (this one: https://addons.mozilla.org/de/firefox/addon/tardis/?utm_source=addons.mozilla.org&utm_medium=referral&utm_content=search) that Firefox identifies as dark, however I absolutely hate any form of dark mode. So far I figured out how to force Firefox to use a light theme everywhere else using about:config, but I couldn't figure out how to change the abovementioned elemtents back to light without changing the theme. So is there any way to declare a theme as light or some other way to change this behavior?

as per my title: how do I move bookmarks to the right side?

ps - migrated today from chrome... and amazed you haven't yet realised how MASSIVELY important customising options are. This place is our virtual home!

stay safe !

Looking for free border designs, and have found the add-on easy search tool required for most of them. Their web site has the add-on for Firefox, but how safe is it? Thanks.

Hi,

Since upgrading to FF100, almost all of the 'select' boxes on my webpages have white text on a white (or very light) background, and are only visible when hovered over, see attached screenshot.

How can I rectify this please?

I have Firefox 101. It is set to open previous session tabs but it does not. Further I am not able to retrieve the ones I used to have available when I open Firefox. I have not cleared the history.

Hello Is it possible to use the stylus add-on to remove the stories from Facebook? I am not a programmer by any mean but i like to "play" with the inspector and i found out that by deleting a node the stories disappear. So I was wondering if i can use stylus to delete this node for me! Thank you!

The hotkey for add-on "600% sound volume" has been broken since the last version of 103. (now 105.0 still not fixed) The hotkey is "Ctrl+Shift+v", which opens the pop-up window of the add-on, and then it allows using arrow key and number to tweak the volume bar. Now all hotkey not working. The arrow keys do not work even if you manually open the pop-up window.
