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.)

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 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!

Firefox has been working fine, but today when I clicked to start, I received an error message. "The file or directory is corrupted or unreadable." When trying to uninstall Firefox, Windows cannot find the uninstall helper. When I try to download a new version, I receive an error message: "Couldn't download - virus scan failed." Windows Security reports are all good. A scan found no viruses. Firefox will not open at all.

Greetings Ya'll,

I have to apologize if this is a double post, but I came back to the forum, & wanted to see if there were any responses, but i could only find my post listed under "My Profile"/"My Questions".

My original post was made Dec. 19-2025

=======================================

Early this morning as I went to use the Firefox browser, on My Desktop, I got an update, & then firefox opened, somewhat.

The homepage did not fill in with favorites, suggestions, etc, and in fact all that did load was the Search bar, but not one of my usual website buttons. The "edit", "help", etc. buttons at the upper left hand corner did load, but that is all. Not one of the buttons work, nor can I close out the Firefox page, by tapping the "X" in the upper right hand corner.

The only way that I could close out the "Firefox Page" was by going through the "Control/Alt/Delete" & then "Signing Out", which would initiate a "Re-start". Once I signed in, I could return to the Desktop, where everything works.

I use Firefox as my Browser on my Android phone, & at this moment, I've not had any problems using Firefox on my Cell Phone.

The only way that I could get to the Mozilla Website was by using the Microsoft Edge Browser, which is not giving me any problems as far as accessing the Internet!

How can I correct this problem, & go back to the Firefox Browser?

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?

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

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 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:

I am having Firefox crash on startup much like Firefox Desktop crashing on startup, initially in version 140, but I have downgraded to version 139 in my troubleshooting and I'm getting the same symptom.

It is frustrating that this does not seem to leave any records in the Windows event log or the Firefox crash reports, and that the fact that there's a known issue of this severity is rather hard to find.
