Hi. Now that the 'Open Link in Split View' has annoyingly replaced the spot previously held by 'Open Link in New Window' i keep clicking on it accidentally (muscle memory).

I don't want to have to retrain my muscle memory, but despite creating css file generated by Claude that should in theory remove the option, and putting it the Profile Folder, it will not go away.

How do i remove it?

Due to muscle menu or not needing to think about it. Split should either be near the bottom of the context menu or you should be able to toggle it in settings. The amount of times I have gone to click a link to open in a new window only to split the view is driving me crazy.

Feedback on Firefox Widgets – Missing Indian Standard Time (IST)

I noticed that the World Clock widget includes Pakistan Standard Time (PKT) but does not provide an option for Indian Standard Time (IST). This is surprising given that India has one of the world's largest internet user bases and a significantly larger population than many countries currently represented.

India operates on a unique UTC+5:30 time zone used by over 1.4 billion people, making it one of the most widely used time zones globally. The absence of IST while neighboring time zones are available feels like a major oversight and reduces the usefulness of the widget for Indian users and anyone who regularly works with Indian colleagues, clients, friends, or family.

Please consider adding Indian Standard Time (IST) to the World Clock widget as a standard option. Its inclusion would greatly improve the widget's global coverage and usability.

System Windows 11 - Firefox 151.0.3 All normal actions from mouse right click have disappeared eg open link in new tab or private window, copy, paste etc etc. The Settings General - Tabs has not changed and previously worked rt click ok. Any help to restore the rt click function will be appreciated.

Previous to version 151.0.1, when I pressed ctrl-L, Firefox focused the URL bar and I was able to edit the URL. Now, on 151.0.1, pressing ctrl-L clears the URL and a dropdown for the search engine appears in the left of the URL bar (see attached screenshot). I have verified this on a new, blank profile. Is there a way to restore the old behavior?

I am trying to disable the text segmentation behavior in latest Firefox(v151), but I have encountered an issue where changing the preference in [about:config] does not seem to have any effect.

Details:

   Target Preference:  intl.icu4x.segmenter.enabled
   Current Setting:       false

   Problem: 
   Even after setting this to false (and restarting the browser), the text segmentation behavior (such as word selection logic) remains unchanged and appears to still be using the ICU4X engine.

   Reference:
   https://support.mozilla.org/en-US/questions/1440483#answer-1638092

I would like to know:

  1.  Has this preference been deprecated or hardcoded to true in recent versions of Firefox?

   2. Is there any other way to disable the ICU4X-based segmenter or revert to the previous segmentation logic?

   3. If this is a known change, is there an alternative preference to adjust how word selection handles specific languages (e.g., Japanese)?

I am using the latest version of Firefox. Any insights or workarounds would be greatly appreciated. Thank you in advance for your help!

Здравствуйте! При установке параметра "Настройки - Основные - Открывать Firefox автоматически при загрузке компьютера" в реестре создается запись HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run - Mozilla-Firefox-E385C0CFD98A494C: "путь-к-файлу\firefox.exe" -os-autostart Что за параметр командной строки -os-autostart? На на сайте поддержки Mozzila не нашел, ни интернет не подсказал. Я понимаю, что это автозапуск Firefox при запуске Windows. Но что конкретно делает данный параметр?

When uploading files with Firefox, I click the upload button, and the file browser window appears to upload files.

For as long as I can remember, it always defaulted to the last folder location that I uploaded a file, but just a few days ago, it stopped working, and always defaults to my home folder.

How can I make the upload window pop up, default to the last uploaded location? My OS is Linux Mint Cinnamon.

Please forgive me if this question was already answered and that I might have accidentally overlooked that answer.

I'm running Firefox 144.0 (64-bit) under Debian 13 (linux).

I want to configure Firefox to never restore any previous session when it starts up, irrespective of how Firefox was last exited.

Even if a running Firefox session was externally killed via some sort of system command or because of a reboot, I never, never, never, never, never, never, never, NEVER (!!!) want it to restart in any previous session.

I ALWAYS (!!!) want Firefox to launch with its default start page, no matter what.

I tried all of the suggestions that I have found on line about how this might be accomplished, but with each one of them, there are cases where the previous session was restored.

I repeat, I do NOT (!!!) EVER (!!!) want the previous session to be restored, under any circumstances.

Is there a way to accomplish this?

Thank you in advance for any suggestions, and again, please accept my apology if this has been answered and I overlooked that answer.

When trying to set Firefox to open a file on Windows 11, it is overwritten by Firefox Nightly. I have both branches installed.

This is how it goes when attempting to set Firefox as a default application in my machine:

1. "Apps > Default Apps"
2. .mp4 (for example)
3. click the button below that displays the current default application
4. Firefox Nightly appears in this menu
5. "Choose an app on your PC"
6. "C:\Program Files\Mozilla Firefox" ... "firefox.exe" ... "Open"
7. Firefox Nightly remains in this menu

I cannot get Firefox to appear as an available app in this menu. The only workaround, although inconvenient, is to drag and drop files straight into Firefox.

Any help would be much appreciated. Thanks.

When I inadvertently press CTRL + R when entering text, it is VERY frustrating because the window refreshed and I loose all of what I typed! Is there some way to disable the CTRL + R combo so the window does not refresh?

Thanks

Hello,

I have two windows in Firefox that I would like to tile so that I can compare the contents of each. Is this possible ? Regards

not a real question and not waiting for answer.

the "Open all in tabs" menu that appears at the bottom waiting for you to click on it by mistake. we need a way to remove that option while also disabling the middle button over the folder to open all bookmarks over the tabs. It also should be a default because been using firefox since version 1 (previously Netscape Navigator back in 1998) and I rarely had the need for something like that.

asked chatgpt and it suggested some fixes but apparently userChrome.css is actively being ignored. from the look of things, seems like I will have to stick to an specific version like I had to do with Thunderbird after version 102 where ugly UI changes were implemented.

have fun.

Mozilla currently allows a user to select an AI Chatbot to use in the updated sidebar. The choices are limited to Anthropic Claude, ChatGPT, Google Gemini, Le Chat Mistral and Microsoft Copilot. When will Mozilla add Grok to this list of choices?

I started using Claude in the side panel instead of a dedicated tab, but there is something noise about it: every time I click to open the side panel the chat starts from scratch. Getting a clean slate is nice, but it takes too much time loading. So I would like to not unload the content of the panel when I close it, just hide it, so when I click to open is already loaded. There is a way to do that?
