There is no Japanese in the language to which the website is translated. It is understandable that Chinese is available in the Asian region. However, we would like to ask why there is Indonesian, Vietnamese and Korean, but no Japanese.

I had two profiles, was in the process of trying to learn how to use the 2nd profile (as seen in the link below), which I still have no answer for. Somehow, maybe I held down SHIFT for too long and clicked on something by accident, idk, but somehow, I ended up REFRESHING the 2nd profile, causing it to delete everything I had done with it, and it backed up the old profile onto my desktop in the process. I figured I could just simply delete the new profile folder it had created and put back my old profile in the profile folder, but now, Firefox will not open at all, saying "Your Firefox profile cannot be loaded. It may be missing or inaccessible." How do I get it to recognize the profile folders again? OMG, I'm using Microsoft Edge, please, get me out of this!

Hello,

I have encountered an issue on some websites where the Japanese text is using the font "Microsoft YaHei" when it should be using "Meiryo." Some examples are on the website bluesky, and bold text on Twitter such as in usernames.

I originally thought it was an issue on my end or in Windows, but when checking other programs and websites such as dengekionline and the non-bold text on Twitter it is using the correct font which I have confirmed via the inspector under the font section. When starting Firefox in safe mode it seems to use the correct font on the previously mentioned websites, so I disabled all my extensions and themes and this did not resolve the issue. I did a Firefox Refresh and this also did not resolve the issue.

I am not familiar with the intricacies on the Firefox about:config to really delve into the exact cause, so I ended up just reverting back to Firefox 134. On Firefox 134 with my same extensions previously the font is now back to Meiryo as it should be which leads me to believe it is something that was changed in Firefox 135. One thing I am considering is that the Japanese text is being recognized as Simplified Chinese by Firefox 135 as Simplified Chinese uses the Microsoft YaHei font as a default.

I have attached some photos that shows my Japanese font settings, and the same post by a user one on Firefox 135 which is using Microsoft YaHei and another on Firefox 134 which is using the correct Meiryo. I have also tried disabling the "Allow pages to choose their own fonts, instead of your selections above" and then restarting on 135, but this did not resolve the issue. Thank you for your consideration.

I use translation A LOT. (I'm learning a foreign language.) It would help to be able to move or resize the results window. Right now, it covers the original foreign language text. I want to compare the translation with the original text and the fixed size and position of your results window makes that a lot more difficult.

For about one week (or more) results of my questions or other input have resulted in suggestions/sites in Spanish. Yes, I live in South America, but I do not speak or read Spanish. I have chosen English as my preferred language. What's up?

Firefox is stuck in a loop! After installing the 145 update, it just keeps asking me to sign into with my admin credentials to install "a new helper tool" over and over. After entering my password nothing happens and when I try to relaunch, the FF icon just bounces. ("Force Quit" shows that the application is not responding.) After multiple attempts, I rebooted my laptop, but it didn't help, as I still get the request for installing the helper too. I'm in the midst of multiple project deadlines and this is very frustrating! Thanks in advance for your help.

When I try to run firefox 141.0 (Linux x64) I get:

libxul.so: undefined symbol: gdk_wayland_device_get_wl_seat Couldn't load XPCOM.

Is there a way to fix this?

I'm using Slackware 14.2.

When I try to open Firefox it opens hundreds of crash reporter dialogue boxes and makes my computer slow to a halt, only restarting my computer can stop the onslaught. Resolving a dialogue/close all doesn't help.

I've tried holding shift to start in troubleshoot mode, but it just opens the crash boxes rather than the 'do you want to start in troubleshoot' box.

I've run a scan with Malwarebytes, no hits, and Windows says there's no updates for me. I can't see any specific crash number, the 'submit' file in my Crash Reports folder says this:

After installing Firefox on a new Windows 11 computer, when I click on the Desktop icon, a Firefox window opens but it doesn't open previous Tabs and the Application menus does not work. I can open new Tabs though and it downloads websites. If I click on the Firefox icon on the Windows Taskbar, Firefox operates normally.

Why doesn't the Desktop icon start Firefox so it works correctly?

Thanks

Hello,

I am looking for help with a Windows 11 Pro 24H2 system. Firefox no longer works despite a clean uninstall and reinstall, including deleting all related folders.

When I reinstall Firefox, the error appears, but the application still manages to launch. However, after a system restart, the issue comes back.

When launching Firefox, I get the following message: “Firefox.exe failed to start correctly (error 0xC0000022).”

I can’t find any recent information about this issue. Thank you in advance for your help.

I always use Firefox Private Window when I go on the Internet. Today, while I was on Fidelity.com, I was suddenly logged out. When I tried to go back to Fidelity.com using Firefox/Private Window, a dialog box on Microsoft Edge appeared asking me to: "Choice: #1 Do you want to make Firefox to be your default" "Choice: #2 Not Now". Which ever I choice I choose, Microsoft Edge will appear with the two above choices. This has been happening repeatedly for several minutes now, so I tried to reach Firefox Support.

My main problem is I cannot access Firefox / Private Window anymore since I was suddenly logged out of Fidelity.com.

Would you please fix this problem. Also, I already selected Firefox to be my default browser long time ago. Why am I being this question every time I go on the internet using Firefox?

I know that this is not a new issue, but it's a recurrent issue that keeps coming back. When I install a Firefox update, MacOS (15.5 at present) often gives me a popup that says "Firefox is trying to install a new helper tool. Enter your password to allow this."

But I don't ever want to enter my password to install a tool that doesn't identify itself. I view Firefox as always being at the forefront of security, but asking for a password for a tool that's not identified is a security risk. Maybe it's MacOS that refuses to identify the "helper tool", but it's a Firefox problem. It's unacceptable.

In today's update, Firefox won't work at all after I hit cancel to the password dialog. I have to Force Quit it. I'm going to have to delete Firefox and reinstall, and hopefully that will work. But I shouldn't have to do this. It's unacceptable that this keeps happening. (If there's some weird configuration issue at my end, I think Firefox should be flexible enough to deal with it.)

I don't know what version of Firefox is generating the problem, because it's currently unresponsive, since I haven't entered my password to install the helper tool. (I'm writing this in Safari.)

(In the attached image, I blotted out my username.)

There always seem to be daily issues, "Mozilla Not Responding". We clear out Cookies, Cache, history, etc. throughout the day. We've had to shut it down and restart the computer. Oftentimes, the system just shuts down.

For the last few weeks, we have an unknown popup from Mozilla, "Unable to load XP.com". Not sure what this may be or why this popup suddenly started. We close it and pops up periodically several times in a day. I am attaching a screenshot of the image.

Thanks

Hello, When I went to launch Firefox after starting up my PC this morning, I was greeted with: "Your Firefox profile cannot be loaded. It may be missing or inaccessible".

I went right to the Mozilla forums and found the help page [https://support.mozilla.org/en-US/kb/how-run-firefox-when-profile-missing...] . In this article it detailed how I should go into my AppData, then Mozilla, then Firefox, and look to see where my profile.ini file is. My profile.ini file was there, alongside the installs.ini and a few other folders. I attempted also to launch the profile manager using run and the "firefox.exe -P" command, but I got the same profile error as when I tried launching the app. The help page then recommended deleting the profile.ini file and then launching Firefox to hopefully remake the default profiles.ini file and enable me to launch Firefox, so I attempted that. When I tried relaunching Firefox, the profiles.ini file did not re-appear in my Firefox folder.

I then tried deleting the Firefox folder itself, and relaunching Firefox. This resulted in it being remade, but with just 2 folders left: Crash Reports and Pending Pings. Obviously that's not ideal, so I right clicked the Firefox folder and used the Windows "Previous versions" feature to restore the Firefox folder to a backup of how it was this morning. I then re-tried launching and I still got the same missing profiles error message. I also briefly attempted manually making a new profiles.ini file with notepad, and pointing it towards my Profile withing my Profiles folder, but that still resulted in the same missing profiles error.

This is basically where I am at now. I have confirmed that I do in fact see my actual profile in my "C:\Users\****\AppData\Roaming\Mozilla\Firefox\Profiles" folder, and as far as I can tell my profiles.ini file correctly points towards it. I did another reset of my Firefox folder to a backup of where I was at this morning before attempting anything. I can confirm my Windows account (Admin, and only account on the computer) has full read and write access to all Folders and files within the Mozilla folder, although I will mention some of the files in the Firefox folder were marked with the "Read-Only" attribute (not sure if that matters, but I tried unchecking those and still no luck)

As far as I can tell I have thoroughly exhausted all the easily accessible tips on the internet for solving this, so I am wondering what to try next?

TLDR: Error: Your Firefox profile cannot be loaded. It may be missing or inaccessible" Already Attempted (And failed): -deleting and prompting a remake of the profiles.ini folder -using firefox.exe -P to launch Profile manager -deleting Firefox folder to prompt a remake of that -multiple uninstalls and reinstalls of Firefox -manually remaking profiles.ini file after it didn't come back after deletion

Will link images of (1) profiles.ini file. (2) Profiles folder.

since 3 days, after initiation of the Firefox the empty page appears with order to close firefox. A have reinstalled the new version several times withour anu change in the program behaviour

Firefox will not update when I click the restart button. Firefox restarts but does not update. Closing Firefox manually (X) several times did not help. I had to restart my laptop and then Firefox updated. This started happening the update before 136.0.3, which is my current version. I don't want to keep restarting my laptop every time there is a Firefox update, which seems to be happening more frequently.
