Windows 11, Firefox 129.02

I've done both a refresh and a clean install and the problem persists. Fonts set to "allow site to substitute"

In Google Maps (maps.google.com), the street names and route numbers (graphic) disappear after a second. This happens in both regular and incognito windows, and regardless of zoom level.

Oddly, when I set privacy.resistFingerprinting in about:config to True, the street names appear, but route numbers are just color boxes. When set to False, I can see both for a second before they disappear.

I've been having this annoying popup about XULRunner encountering an error. From what I've read, XULRunner is a legacy integration with Firefox. Sure enough, I see Mozilla Firefox installed. But un-installing it doesn't help. Soon, it is re-installed, and the error comes back. I have a feeling that some application is using XULRunner and Firefox as a component, but I don't know what it could be. Is there any way to find out, and stop that application from installing Firefox and XULRunner? Or at least getting its problem fixed?

Hello! After being away from my PC for a few days I tried to open firefox and got this error:

'Firefox is al actief, maar reageert niet. Het oude Firefox-proces moet worden afgesloten om een nieuw venster te openen' aka 'Firefox is already running but not responding. The old Firefox process must be closed to open a new window'

I deleted the application in windows settings and then redownloaded it. The problem persists. What can I do?

I have 2 laptops, one for work and one personally. I was looking to set-up firefox on my personal laptop as well but noticed I cannot open developer console on a specific element by pressing 'q' anymore after right clicking.

This is a significant feature and I would like to keep using it. Is it possible to enable this feature on my personal computer as well? Since it is still enabled on my work device.

i received a secure connection failed message when trying to load one of my favorite sites You say to contact the site about the message, but there is no way to bypass the message to contact them This logic defies all description I share no personal info with this site, its just reading material How can I get to this site?

google apps block pops up in upper right corner of gmail each time I change focus without selecting it

I have cleared cache and history. Still pops up. This happened after the last update to Firefox.

Firefox should definitely add a dedicated option in the toolbar to make switching between profiles easier. Currently, the only way to do this is through the "about:profiles" tab, which is much less convenient than the profile switching options in other browsers

Hello. How do I do if I want Firefox to open a new window every time I click on the icon? I tried to insert the command "-new-window URL", which used to work before but it doesn´t anymore. Is there anybody out there who knows something about this?

The Adobe Acrobat Add-On Extension for Firefox was missing so I attempted to add it from Adobe Acrobat Pro 2017. I have had to do this manually by installing from the adobe_acrobat-1.0-windows.xpi file. This usually has worked. When i tried to add it this time is said the add-on file was corrupt.

I tried uninstalling and redownlading AdobeAcrobatPro 2017 thinking this would add an uncorrupted file and got the same the same message. Unfortunately, because I had used the Adobe license key too many times for Acrobat 2017 on my computer I had to upgrade to Adobe Acrobat Pro 2020. i had hoped this would solve the problem. But no, I get the same message corrupt file message even with a new copy of the Acrobat Pro 2020.

What is going on? Can anyone help with this?

Hello guys,

The trouble I ll present you might come a bit late, I've just never thought about asking on this forum (didn't even know that it exists lol) and I spent a lot time on tutorials trying to find the solution... lol 😩

My situation : I have a laptop with debian 12 stable. Early July, I updated my apps, Firefox 128 has just been released. Since the Firefox 128 update, I can no longer execute Firefox, I always get the pop up message :

Failed to execute child process (no such file or directory)

I've tried many times to uninstall & reinstall, purge & reinstall. Still the same "failed to execute... " message. all the subsequent updates (128.X and 129.X) haven't solved this problem...

On the other hand, Firefox ESR 128 works like a charm.

Is anyone in the same situation as me ? 😕

Wishing you a nice day :)

Hi, I asked the question below a year ago and unfortunately didn't see the response until now.

"Firefox closes unexpectedly" https://support.mozilla.org/en-US/questions/1417756 Thank you Paul for your response!

I followed the advice but there are 'no' crash reports are created when this happens.

It always seems to be when I'm typing in a text field (and possibly typing control keys too).

I've googled 'short cut' keys for Windows to see if something I'm typing is doing it but haven't found anything.

So other than installing a keylogger on my device is there any other way to figure out what is going on?

Does Firefox have a log file? If so is there a log that says ..."User closed the browser". That would tell me it is me typing something in that is somehow telling the browser to close.

I also don't see any app crash reports in MS Event Viewer. Will Firefox crashes show up there?

Thanks again for any help or guidance you can supply!

Hello! I have been having certain visual bugs occurring within the Firefox browser, I do not know what's causing them but am hoping someone can help! Firefox keeps on adding or changing translucent white boxes to multiple websites, I have some from YouTube attached below but I've had this issue on multiple websites. I'm using an ARM architecture Surface Pro X and when I reached out to Microsoft they couldn't help me since the error was just in Firefox.

Hello, I get crashes when I watch videos on Twitch or YouTube. They happen every half hour UUID 4ff8ecc7-72f0-43dd-a092-3bf250240829

On using Google search, many times it behaves as if I've done nothing...

Communication between Firefox and their server seems dropped. Press enter/search and... nothing

Or do they* want us to use Chrome?
