I-Firefox Community Forum

Hi there, I'd like the option to unbind default keybindings. Specifically, the Ctrl+W to close a tab binding. I reflexively hit ctrl+W when I want to delete a word in a text box (from emacs/shell/vim/etc) and this has resulted several times in me closing the tab I was on and losing the text I was writing. It would be useful to me to be able to disable this keybinding so that I don't continue having these accidents. More generally, I imagine that some users will find some keybindings annoying and want to disable or maybe remap them.

So this is half a feature request, and also half a support request if anyone has suggestions for workarounds in the meantime.

I already tried setting geo.enabled to false as suggested here: https://support.mozilla.org/en-US/questions/1475504

Is still get the prompt every time no matter how often I decline.

I'm experience trouble with firefox loading pages. It seems that some pages (about 1 in 10) will not load first try. Instead it results in either a "unable to connect", "Hmmm... Can't reach this page" or simply a blank page. I have not noticed any pattern in the pages on which this occurs and they all display correctly after a refresh. This problem only occurs on firefox. I have already tried disabling the proxy without any success. I'm looking for any suggestions for solving/diagnosing this issue.

I recently got into Bazzite and I'm currently working on understanding and migrating to this OS, one of the things that got my attention is the PiP mode, which by default doesn't stay on top of other windows, and that made me think about the whole purpose of this functionality to begin with, anyway this led me to think about my best idea ever which is to add "some option" in which the user can choose what is his preferred PiP window behavior and set it as default, so he don't go through all the process again and again.

I have two websites of my own. I am viewing one and it is correct. When I view the other, it uses the https cert from the first one, and says my site is not secure. I have viewed the cert, and it is definitely correct. I think Mozilla is probably caching old information - the certs have been correct for most of 2025, so it is a pretty old version. Therefore, it is not actually caching the cert, but caching which cert it should use. I have tried clearing the cache, and it did not help!

Has Mozilla got some kind of cache I can't clear? Should it not re-read the cert when it loads the site, or at least the cert date, each time it reads the site (ie was not previously showing it on screen)?

I edited a video on my MacBook Air M3 (8GB/256GB) using QuickTime Player and replaced the old video file in my Next.js project folder. After pushing the updated code to AWS Amplify, the website displays the new video correctly in Chrome. However, in Firefox, it still shows the old video with a watermark.

At first, I thought it might be a caching issue, so I disabled the cache in Firefox, but the problem persisted. To troubleshoot further, I ran the Next.js project locally and tested it again in Firefox at localhost:3000. Surprisingly, Firefox still displayed the old video with the watermark, confirming that caching is not the issue.

Can anybody explain me the issue Website Link Video of the issue Video of the link

You can see a Freepik logo appearing over the video in Firefox, but it doesn’t appear in other browsers.

Some extra info to help you 1. This glitch occurs in all OS {windows , mac , linux} 2. I tried to test in whole new devices it occurs on those devices also

Здравствуйте, при скачивании плагина с интернета, скачивание происходит, полоска загрузки заполняется на 100%, но сам файл не скачивается, как будто зависает на этапе проверки. Ждал очень долго, так и не скачался

Hi,

I have 3 devices with the same Firefox account : a phone, a work pc and a personal pc. I don't have bookmarks sync on any of my devices. From my phone I can access (read only) my bookmarks from both my pc. It seems I can't do the same from a pc to another. Am I missing something or is the feature not implemented?

Thanks

Hi, I am trying to login to a retirement account that Firefox/Mozilla is blocking. The site works on another browser, but, since I like to use Firefox exclusively for online work, I would really like to access the login there. Any suggestions? work arounds? I get an access denied ERROR 15 "This request was blocked by our security service" instead of the login. Since this site is a retirement account site, I cannot give more info.

My DSL router is at 192.168.0.1. Every time I log in to the admin account from another 192.168 box, Firefox balks because the router uses an evil self-signed certificate from the manufacturer. Is there any way to accept the "risk" permanently? It is an impediment to productivity having to wade through banners proudly proclaiming how dangerous my router is among warning messages and do you really want to ignore our safety warnings and corrupt your system you stupid user who, after decades of experience, cannot decide for yourself if your router is clickbait full of trojans and viruses that don't work on Linux systems anyway. Go bother Windows users with such utter nonsense. I don't need your Windows safety wheels. Solution: provide a way to turn off the miasma in about:config, safely hidden from naive Windows folk, for 192.168 networks.

I've been using Firefox on device A computer in the evening, and the next day, after opening device B computer from sleep, a tab was open from the device A session (along with some older tabs I kept open, it was placed at the most right location). I am 100% certain I did not have that tab open from previous session on B.

The only way this tab would be able to appear on device B is if I somehow triggered a "send tab to device" functionality when working on device A, however, I am 100% sure I did not. Seeing how I would have to right click the tab and select a submenu to trigger that, it seems essentially impossible that I did that by accident.

Q: 1. Is there a keyboard combo that could be accidentally hit that would trigger Send tab to device? As far as I could research, there is no such shortcut. 2. Can a website trigger this API and perhaps I approved it by accident? I would definitely also notice this. 3. Is there a sync audit log I could check on either device to see if a tab was synced? I found about:sync-log but nothing really useful in there.

This event is so weird that I am considering secirty aspects or a potential exploit vector..

Enabling HDR (gfx.wayland.hdr) on Linux CachyOS causes random lines to appear on the screen, both vertically and horizontally seemingly at random. Perhaps important to note that the OS originally didn't recognize my laptop display's HDR capability so I had to "force" it on with KWIN_FORCE_ASSUME_HDR_SUPPORT=1, but it still can't actually read the display's specs from EDID. Disabling gfx.wayland.hdr fixes the issue but I do really like HDR so I think I'm willing to live with it for now.

The release notes for 142.0 say:

  Keep an active tab visible in a collapsed tab group
  Focus on just one tab in a group without the clutter. Your active tab stays in view, keeping
  things tidy even with the group collapsed.

But it does not define what an "active tab" is. I usually have a group which never collapses, it always has one or more tabs visible no matter what I do. Is this a bug? Or is there some way to stop tabs from being 'active'?

I've just updated my Linux Mint to 22.1 and Firefox to 142 on two computers. Both show the same behaviour. On websites of the Stackexchage family (Stackoverflow, Superuser, Crossvalidated, Academia...) the comment function seems to not work anymore. I am not offered a button to comment, and clicking buttons to see more comments that are already there don't show the comments but rather send me to the top of the page. I can still answer. The problem seems to be with Firefox 142 as it worked well before the update, and it still works well with Firefox 142 on Mac and other browsers on Linux.

This looks like a minor bug, not sure whether it is specific to Stackexchange or other websites are affected, too. Is there any help? If not, where can I file a bug report?

I noticed earlier this week that one of my extensions is still having a major bug, despite said bug being patched a month ago and the update being approved already. The extension was set to auto update, so I tried disabling it and checking for updates manually. Firefox said an update was available, so I hit update and nothing happened. Even after waiting 10 minutes, refreshing `about:addons` and even restarting firefox, the update was not installed. I can't check dev tools for information on what happened either since they are handled by the firefox app itself instead of the `about:addons` page. So I turned off auto update for all extensions to see if it was just that one that was having an issue, but none of my extensions have been updating. 11 updates available, none able to install. The only way I could get an extension to be up to date was by completely reinstalling it, which removes all extension data and thus is not an option.

Srry I don't see the button to delete the question, because I didn't even differentially diagnose whether it was even Firefox or a webcam program that was running

Playing a video in a Firefox tab prevents my desktop from hibernating, even when the video is paused.

I'm guessing this is an advanced settings in about:config somewhere, possibly.

I multitask a lot so I was partway through a video on utube and paused it, & then my computer was still awake in the morning.

The simple solution : don't do that then; or, it's just a little bit of electricy, don't even worry about it.

I looked around for solutions in Debian or wherever & they talk about VLC playing, but this was a Firefox tab.
