My laptop lost power mid-session and since then Firefox hangs after opening and becomes unresponsive. Can’t do anything on it. Troubleshoot mode does the same. Booted up my computer in safe mode, no change.

I’m guessing a reinstall would fix it but I had a bunch of tabs open that I’m really trying not to lose. And I didn’t have an account to save them, I’ll rectify that after this.

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?)

How to PROPERLY erase history? I mean, you erase HISTORY...click...there you go...?!?!?...but, what's happening? I erased HISTORY...ah, I erased it FROM the panel but, it WILL remained on the list that it shows on top of the icon (sic) ...someone suggested to go on the panel, select privacy, scroll to history, pass over "Never remember history...." (?) AND then you "click"... Clear...what is the point? clear means clear means clear from EVERYWHERE...sorry about the mess I wrote but I was frustrated

Today May 1, I noticed that any website that shows a recaptcha checkbox, including the google recaptcha demo (https://www.google.com/recaptcha/api2/demo) only shows an infinite spinner in firefox v125.0.3. I've tried the same sites in chrome and edge and the recaptcha works fine. In FF, I have cleared my cache, disabled tracking protection, disabled anti-virus and tried troubleshooting mode - still get the infinite spinner. Last week, I had no problems with recaptcha.

For quite awhile I have had an intermittent problem when watching YouTube videos. To watch a video I right click on it and select "open link in new window". If I just click on the video to watch it, the main page may reload when I click on the back arrow and some of the videos I was interested in are no longer displayed. Sometimes my touchpad doesn't recognize the right click and opens the video in the current window. After it starts playing, if I click the back arrow, the video returns to the previous page (which may be reloaded), and sometimes the audio from the video keeps playing, so I have audio for a video that is no longer visible. When this happens, if I click on another video, the audio from both are played. Today I had the same thing happen when I was streaming a TV program from the Spectrum website.

1. If I click on a YouTube video from the main page, should the main page be rebuilt when I click on the back arrow? 2. How do I resolve the audio continuing to play problem? i don't know if this is a Firefox problem but I have no idea where to start to fix it.

Recently a popup notification came up when I opened firefox on my mac. Its been awhile since I opened it and without thinking I clicked : o ~ Now I worry if it'ss ledgit? Does Firefox give a popup box in top right corner when it needs an update? I wasn't on any strange website or anything but I'm always concerned and dont remember seeing that before.

My firefox now says its up to date after it restarted ~ it's running 125.0.3

Any advise is appreciated.

I just migrated to iMac 2019 27" with Venture OS from imac with Yosamanite. Firefox looked weird with TINY tabs and search window, Too much space. I've tried updating and restarting Mac but no change. Same with themes. You can see the screen with open Firefox.

Hey,

I use a personal firewall. Every unknown program that attempts to access the network triggers a popup message requesting permission.

Right after the installation, Firefox.exe initiated a message, stating the following path: "C:\Program Files\Mozilla Firefox\firefox.exe". I granted access.

However, weeks after the installation, the updater.exe asked for permission, stating a very unusual path of itself. The path is "\device\harddiskvolume3\Program Files (x86)\Mozilla Maintenance Service\update\updater.exe".

This seems unusual to me, since apps normally use 'C:\' to refer to harddiskdrive0. It is also suspect, since there are only two drives connected and the Disk Management tool (as an admin) indicates, that there are harddiskdrive0 and harddiskdrive1. There are no hard disk drives 2 or 3.

I also wondering about the fact, that the about firefox screen states, that firefox is up to date - even I did not granted access for the updater.exe in the past. There has never been a firwall rule to grant access for the updater.exe - how did it update in the past?

Does anybody have an idea what is happening?

Best regards, André

Why is Firefox autofilling the address bar with URLS I've never visited? There is a question on this from 5 years ago, with lots of suggestions. My problem is that Firefox is autofilling with sites that contain confidential login information.

When I open the application it loads as a small window that I have to maximize to make it full screen. It never used to do this so I need some help to fix this. I've taken a quick look through settings etc and can't see anything wrong...

Yesterday I was unable to sign into The Guardian website (https://profile.theguardian.com/signin?INTCMP=DOTCOM_NEWHEADER_SIGNIN&ABCMP=ab-sign-in&componentEventParams=componentType%3Didentityauthentication%26componentId%3Dguardian_signin_header and https://profile.theguardian.com/signin? )

The problem is that after I click "Sign In", that little circling line becomes the Energizer Bunny, circling away and circling away, but not logging me in.

I have no problem logging in using those login pages on Edge, so confident of username/password combo

I have (repeatedly) turned off tracking protection, Adblock Plus & Privacy Badger for the site, cleared history (cookies and cache, as well as all), followed the complete set of instructions at https://support.mozilla.org/en-US/kb/fix-login-issues-on-websites-require-passwords, and refreshed Firefox. Still the same problem.

HELP - I don't want to be forced to use Edge :)

When I press the pause button on my keyboard, it doesn't stop the YouTube video like it used to. I'm not sure why it stopped working. I've checked the key, and it works fine in Chrome.
