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:

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.

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?!?

Here is the extension i would like to convert

How do I fix?

Thanks for any help!

mouse pointer is nice size in general but becomes VERY small when I go into websites. this happens when i use either floorp or firefox but is fine when i use chrome( would rat5her not use google). i just don't see where I can fix this in Firefox settings

I've been seeing the black embed icon appear when I select text. It's only been recent. My browser is 125.02 and up to date and I have Windows 11.

Is this from a recent update? I'd like to disable it if possible.

I attached a screenshot.

Thanks in advance!

At one time, I was able to swipe left on my trackpad and go back to the previous page on firefox. I can't seem to find where to set that preference. I'm running MacOS.

The past two days Ive had about a dozen addons all updated with the same similarity, i.e.

visited-color picker 1.2resigned1

Every one has not been updated for 6-7 years. I don't see any release notes. Is this some sort of qualifying re-certification procerss?

in the firefox browser is there any way to see the casting the browser screen to chromecast on tv. similar to 'cast to media device' in edge browser or chrome browser.

I currently have a 'bad/rouge' session of Windows 7 Firefox (don't really know how that happened) open (7 'Windows', each with one empty Tab plus 1 'Window', with only 1 populated tab (Yahoo Mail)! I need to close Firefox in order to restart my laptop (strange things have been happening, including not being able to access the internet)!! On restarting, I want to be able to open Firefox with the previous session I had with my 8 'Windows', each with dozens and dozens of Tabs! Please help, I sorely need those many 'Windows' and Tabs!!!

Hi,

I have managed to figure out ways to remove items from context menus from various pages here and around the web however it always seems to leave an additional unwanted separator line that I cannot find how to get rid of.

There are a number of additional lines I am looking to remove but the current one that is annoying me (based on most usage) is the additional line between 'Copy Link Without Site Tracking' and Search which is an add-on - Simple Context Search - https://tinyurl.com/yck5c (as shown in the attachment).

I did have 'search google for...' directly above the 'Search for Google' option which I removed.

I also removed 'Copy Link' which was above the 'Copy Link Without Site Tracking' option which I also removed.

Hope the above makes sense and any help greatfully appreciated.

Thank you

Greg

Please see the attached screenshot. I get this popup EVERY TIME I open FireFox. I've tried a number of different suggested "fixes" from Google Searches with no success.

I want this popup GONE.
