Firefox 技術支援討論區

Dear People --- FIRST: I apologize for taking so ling. I had physical probs, that kept me from coming back. SECOND: I'm afraid that I can't solve this problem with the advice provided. There was a file mentioned [which slips my mind, and I can't look for it with out leaving this screen] that is supposed to be on my desk top. I couldn't find it, so things stopped there.

SO..... I'm reiterating my problem: I loaded an "update" to Firefox that was supposed to get around the obnoxious "THIS BROWSER IS NO LONGER SUPPORTED" message I'd get on certain web-sites [such as the Milwaukee Journal]. I never understood that, as I am careful to update programs, when the updates are available. SO: While I was on the Milwaukee Journal Site, I clicked on the "Firefox Update" that the Journal's site recommended. What happened was I got the Current Version, and LOST all of my add-ons. After problems I can't go into here, "The Cat's Back." Please advise whether I can get things back after this much time.

N.B.: I'm running Windows 10.

I'd like to be able to open a link in private mode by holding down some modifier key, then clicking on the link. There are many times that I want to open a link in private mode, and a keypress + click would be the quickest way to do it given that one hand typically remains at the keyboard while I use the mouse/trackpad.

I've even added a toolbar button to open a new private browsing window, then dragged and dropped a link onto the button, but that gets a circle with slash icon and nothing more.

Others have asked this question, so, to be clear, none of the following address my question: copying the link then opening the private browsing window & pasting the link, using a customized shortcut/bookmark, opening Firefox in private mode via command line, right-clicking the link then selecting "Open link in new private window".

Thanks for any advice and thank you, Mozilla, for Firefox!

I've recently started using the Tree Style Tab extension, and I'm finding it useful, but I'd like it if the list of tabs could be automatically hidden when only one tab is open (and automatically shown when more than one tab is open).

I hoped to write an extension to do this, but opening the sidebar from an extension requires a user gesture, so I suspect I'll have to use a userchrome.js script.

From a "userchrome.js"-like environment (i.e. unsandboxed AutoConfig), I can hide and show the sidebar with `SidebarUI.hide()` and `SidebarUI.show("treestyletab_piro_sakura_ne_jp-sidebar-action")`, and I can examine the tabs open in the current window via `gBrowser.tabs`, but I can't see how to get notified when the number of tabs changes (replacing `gBrowser.tabs` with a proxy doesn't work, for example). I suppose I could just check every few seconds? That feels like a bit of a cop-out, though, and gets more and more inefficient the more windows are open.

There's an API for extensions to receive events when tabs open and close, so clearly this is possible. Where should I be looking for this functionality?

(I also don't know how I would go about unregistering an event listener (or cancelling a setInterval call!) when the window closes, assuming that's necessary to avoid leaking resources – is there an event like `chrome-document-global-created` I could listen for, but that fires during teardown of the window rather than when one is created?)

Hey,

So the issue i have is when i'm trying to access my gmail accounts from Mozilla. Whenever i try to access my mailbox or gmail site in itself it transfers me to outlooks login. I assume there's some setting or similar that i'm missing that's causing the issue but i haven't been able to find it.

I've narrowed it down to not being any add-on since i only got few but none of them should affect anything email related in anyway shape or form. Also it works fine in Chrome which has been my go-to go around for the issue but honestly it's getting a bit annoying.

Any help would be greatly appreciated. Thanks in advance

Hello support,

is there any way (other than the one plugin I found that did not work for some reason) to adjust firefox' general brightness (or that of an individual tab) ?

Also changing my monitors brightness would not work for me as I am trying to test a website I develop (using firefox to visualize it) and it is rather just the large difference between my editor (which's brightness you can not adjust) and the browser that is very unpleasent when I switch back and forth (like when trying to fix a bug).

Kindest regards.

Hello, I want to get funky looking tabs like this:

https://imgur.com/a/Xbc4Kih

But I can't figure out how to do it. I've tried searching for a way to do this, but everything I find is very old and doesn't work. One thing I keep finding is this: https://github.com/wilfredwee/photon-australis

But that doesn't work for me, it just makes the tabs less tall. I've tried switching to nightly and that didn't do anything so I'm pretty lost. I don't know CSS or anything so I cant do it myself.

If anyone knows how to do this then please tell me!! thx!

Hello, I'm looking for a way to add a shortcut, similar to:

CTRL + Click = open link in new tab SHIFT + Click = open link in new window

What I want it to do is open a link in a Private mode window, to avoid having to open the right-click menu.

I came across this person asking for something similar (they specifically want the private window to not appear on top, I do not care if it gets automatically focused or not) https://support.mozilla.org/bm/questions/1317416

The only answer links to a list of "command line options" and points to the private ones. I understand how you can use these to change how the Firefox shortcut behaves, or to open Firefox in a specific way from the "Run" command, but I do not know how, or if it is even possible to apply these settings to a specific shortcut-click combination.

I have recently refreshed Firefox on my laptop running MacOS. Previously I had changed the full-screen-transition in about:config to be zero, but since refreshing changing the setting hasn't disabled the transition. My config is this currently: full-screen-api.transition-duration.enter 0 0 full-screen-api.transition-duration.leave 0 0 full-screen-api.transition.timeout 0 Despite everything being like before the transition persists... I'm currently on the latest version of Firefox (125.0.3)

So on my macbook when I enable fullscreen the anmation is super weird. first it stretches the video to the top and then just expands to the whole screen, when I go out of fullscreen is stretches to the bottom and then goes out off fullscreen. for example on safari it just expands the video until it takes up the whole screen. I have gone in about:config and disabled the fullscreen animation but that did nothing.

Still using Firefox 78.15.0 esr (64 bit)

Am I correct that the toolbar icon " - | 100% | + " is the Firefox Zoom function? I have never been able to locate a toolbar icon for NoSquint Plus. I also have Theme & Font Size Changer, but it stopped working years ago. Anyway, working fine for many years, automatically setting the zoom on every tab to 150% so I can read it easily.

A few days ago I got into the NoSquint Plus preferences (NEVER OPEN THE HOOD !!!) , and wondered why it was set to chrome API instead of CSS API and changed it to see. That kind of broke it completely. Maybe changed other stuff trying to get it back...

At present, Firefox Default Zoom is set to 150% . NoSquint Plus is default full page 100% and default text only 150% There are no instructions telling me how these 3 settings will interact.

It seems that when I open NoSquint Plus Preferences and change the %, it works on all the tabs on that page, but not on any other page unless I open it & fiddle with it.

How do I get what I want? There is no "return to default settings" for NoSquint Plus.

I would like the address bar to show what it would show when you type a "?" just by clicking. It's a default feature in chrome, I know, mentioning a competitive browser as an example is kind of a no no, but it's the only example I can think of.

I have tried to install my password manager Sticky Password several times to the firefox browser. The current version of sticky password is installed and running but the firefox browser leaves me a message saying it is not installed or running.

Sorry, posted recently and had then trouble finding out how to respond to help offered (jscher2000)! Noticed that the email version was "no-reply" so I didn't figure that would work! So, I tried to 'cut and paste' my reply (on a smartphone) and I ended up losing even the email reply text so here is a reconstruction. I tried the suggestions in order and the first one didn't have a "Restore previous session" option and the second one had "Recently closed windows" greyed out! And, when I entered "about.support" in the address bar (top rightish), I received a notice that I couldn't reach Google (Remember that I don't currently have internet access on my laptop). So, no joy there either! Can I not just change some current setting to prevent Firefox v 115.9lesr from saving the current 'Windows' and Tabs so that, when I again open Firefox, the previous session 'Windows' and Tabs would be used?!?

I made a small CSS customization to my tabs in FF 115 ESR on Windows 7, so they would be flat on the bottom and rounded on the top, looking a bit more like tabs instead of buttons.

Looked ok in FF 115 ESR.

However, in FF 125, half the tabs are now cut off, including their text (see attached images).

Also the tabs background is darker in FF 115 ESR, providing more contrast between the tabs and the tab bar. In FF 125, it's almost all white and I can hardly distinguish between the tabs and the tab bar.

Why is there such a big difference in appearance between FF 115 ESR on Windows 7, and FF 125 on Windows 10?

Here is the code I used...

/* ------------------ RESIZE TAB BAR ----------------------------- */ \#TabsToolbar { height: 27px !important; margin-top: -1px !important; margin-bottom: 0px !important; } \#tabbrowser-tabs { height:25px!important; min-height:25px!important; }

.tab-background-start[selected=true]::after, .tab-background-start[selected=true]::before, .tab-background-start, .tab-background-end, .tab-background-end[selected=true]::after, .tab-background-end[selected=true]::before {

 min-height:25px!important;

.tabbrowser-tab {
 max-height: 25px !important;
 border-color: #8f939e;

 max-height: 25px !important;
 border-color: #8f939e;

} /* ------------------ TAB HEIGHT END ----------------------------- */

I inserted backslashes at the beginning of the first 2 lines of code above to preserve the hashtag sign (otherwise it displays an index number before those lines), please ignore the backslashes.

I would like my customizations in Firefox 125 to look like the ones I made in 115 ESR.

Is it possible?

Thanks!

Hello everyone,

Why some Wikipedia pages cannot activate reading mode under Debian 12 and Firefox ESR 115.9.1, for example this English Wikipedia page on Emmabuntüs does not allow reading mode to be activated while French, Spanish and German pages can ?

See our test video on this subject: http://share.emmabuntus.org/Accessibility/Firefox_mode_lecture_non_disponible_emmabuntus_en.mp4

Is there a utility to test pages compatible with reading mode?

Or otherwise in which Firefox log file to see if a page is compatible or not?

Thanks in advance for your help.

Here is the extension i would like to convert

https://chromewebstore.google.com/detail/equalizer-for-chrome-brow/abikfbojmghmfjdjlbagiamkinbmbaic

here is what extension test .com says

2 compatibility issues found:

What are compatibility issues?

Compatibility issues warn about the usage of APIs or permissions not available in the latest version of Firefox.

How do I fix?

Thanks for any help!
