My very favorite browser will not open when I click the FF icon. I did another download and it will not open, as well. What can you tell me about this issue and how to fix it? An avid user for many years.

Recently I'm having an issue with Firefox that makes it so when I try to open it, it simply refuses to do so. Say on my desktop I double click the icon it will open for a split second and then instantly close and refuse to do anything afterwards. This is very frustrating, and I haven't yet discovered a solution and would really like to be able to use Firefox again. What is really strange is that this is a persistent problem not only on my laptop but at my pc as well which are two separate devices. If anybody can help or has experience with this problem to offer incite it would deeply be appreciated.

I submitted a question earlier about not being able to use DocuSign. jonzn4SUSE was very quick with a response that worked perfectly. However, when I tried to mark it solved, I got the following error message. In addition, I didn't know where to find my original question so I could thank Jon and mark the issue closed. Where should I have looked for it?

Looks like there’s a problem with this site

When I click on headlines for Yahoo Sports articles, the headline is centered on my screen, but the article is on the right periphery with only the very left portion of the article visible. I don't know how to center the article to make it legible. This problem only occurs with Sports articles, not with Yahoo news of finance ones. How do I fix?

Hey, I have recently installed Zen Browser because of a friend's suggestion. Although I really loved the fresh vibe of the Browser in comparison to what I was accustomed of which is Chrome. But after some initial hassle of setting up the browser I figured one thing that although I have a 100Hz external monitor and a 90Hz Panel on the Laptop the Webpages while scrolling it felt that it was somewhere 45-60Hz. I tried the UFO Test as well but there I was getting 100Hz but whenever I visited any website (say LinkedIn or even Youtube) the page seem very very laggy and it made me switch back to Chrome (Honestly I wanted to stay on Zen only) but the problem forced me to switch back. I understand that the browser is still in its Beta Phase but still the experience I had it was not good. Hope I can get some resolution and hop back to Zen as I really want to.

PS - I have tried all the fixes from reddit pages, Hardware Acceleration, Smooth Scrolling, etc. none works.

Mozilla Firefox 115.25.0 (x64 en-US) won’t close since my previous version was updated on 6/29/25. I have tried closing it in my Win7pro Task Manager on several occasions, and had even tried to uninstall and then reinstall it from my “Programs and Features” menu, but I keep getting a message that the program can’t be uninstalled until it is first closed. Nothing I do fixes this problem. HELP

Hello to those of you reading this,

Over the last five or so days, my Firefox has been acting in a wholly unpredictable way. Every time I launch Firefox, the inspect element tab will open and close itself repeatedly for about 3-10 seconds, stop for a bit, and then start again. CPU usage by Firefox skyrockets whenever the glitch occurs.

I have tried Troubleshoot mode, I have tried a clean install, I have tried to refresh Firefox, all to no avail. This doesn't seem to have anything to do with a Firefox update, as the last update to my Firefox was well over a week prior to the start of this issue.

I am running several extensions: uMatrix uBlock DuckDuckGo Privacy Essentials DecentralEyes PrivacyBadger BetterTTV Facebook Container Firefox Multi-Account Containers TTV Ad-block Wikipedia Context Menu Search Redirect AMP to HTML

However, none of these seem to be the cause of this issue as it persists in Troubleshoot mode and after a Firefox Refresh.

The only reasonable lead I have regarding this issue is that the browser console spams the error messages as can be seen in the image attached to this post. A recurring element is "server0.conn0.watcher2.process16". I'm afraid I know only enough about coding to understand that this is probably the root of the issue, but am completely lost on how to fix it.

Another tidbit of information, whose relevance I doubt but am including nonetheless, is that I recently transferred my C:/ drive from an SSD to an NVMe. I'm wondering if perhaps the application is trying to call on a process stored on the other drive. I find this unlikely, as similarly to the point on the Firefox version this only started occurring a week or two after I transferred the drive over.

Any assistance on this matter would be greatly appreciated!
