Firefox supportforum

Starting today (Apr 30), when trying to open firefox the following message appears:

"Firefox is running, but not responding. The old Firefox process must be closed to open a new window." My options are to close firefox or cancel.

When selecting close firefox, the message will reappear with the same options. I am unable to run.

Steps I have taken: Uninstall Firefox Download latest Install

Message still appears

Every time I open Firefox another blank window opens behind the main Firefox pages . I see it when I close Firefox so have to close that too. There is no URL in the window just a blank page.

With the latest version of Firefox the menu, etc. have a font size that is TOO SMALL. There are many Mozilla posts about this problem.

My wife cannot read them. I can barely read them. If this is not fixed soon, we will switch to another browser.

Can the Firefox code writers fix this?

Hello, I'm looking for a way to add a shortcut, similar to:

CTRL + Click = open link in new tab SHIFT + Click = open link in new window

What I want it to do is open a link in a Private mode window, to avoid having to open the right-click menu.

I came across this person asking for something similar (they specifically want the private window to not appear on top, I do not care if it gets automatically focused or not) https://support.mozilla.org/bm/questions/1317416

The only answer links to a list of "command line options" and points to the private ones. I understand how you can use these to change how the Firefox shortcut behaves, or to open Firefox in a specific way from the "Run" command, but I do not know how, or if it is even possible to apply these settings to a specific shortcut-click combination.

Hello! I've recently switched to Firefox from Opera. However: After the browser Closes, It will always Refuse to boot up. Even Shift-Click Doesn't work. It opens, but Crashes almost Instantly. OS: Windows 11 (Build 23H2)

I followed instructions for adding bookmarks from html file. Got to "import from html" . I can see the html file I want to access, but when I push "open" nothing happens.

I would like the address bar to show what it would show when you type a "?" just by clicking. It's a default feature in chrome, I know, mentioning a competitive browser as an example is kind of a no no, but it's the only example I can think of.

after updating newest the version of Firefox the option to" restore previous windows opened " does not work. Is there a work around when I close my browser and then reopen the browser so that all the tabs that I had opened before closing my browser return as if I never left?I went into my setting and have the "open previous tabs" is checked. I even restarted my browser but nothing simple seems to work. Thanks in advance

I have tried to install my password manager Sticky Password several times to the firefox browser. The current version of sticky password is installed and running but the firefox browser leaves me a message saying it is not installed or running.

I'm trying to watch videos on Disney plus and Amazon prime. I can't get them to work. I tried various tutorials but many were irrelevant because they referred to google chrome which I don't even have. I tried checking and unchecking the enable DRM checkbox. Widevine never seems to update. I do not know how to install in manually.

I've made an extention which works fine when I test it using the temp mode on firefox. When I attempt to install from file however I'm told it could not be installed as it appears to be corrupt. Below are the package.json and the manifest.json:

package.json

{

 "name": "ext",
 "version": "1.0.0",
 "description": "",
 "main": "contentScript.js",
 "scripts": {
   "test": "echo \"Error: no test specified\" && exit 1"
 },
 "keywords": [],
 "author": "",
 "license": "ISC"

}

manifest.json

{

 "manifest_version": 2,
 "name": "SKUORG",
 "version": "1.0",
 "description": "Organises SKUs on WooPage",
 "permissions": [
   "activeTab",
   "webNavigation",
   "<all_urls>"
 ],
 "content_scripts": [
   {
     "matches": ["<all_urls>"],
     "js": ["contentScript.js"]
   }
 ]

}

I have tried on two devices / installs of firefox and have followed the steps I could find on this page : https://support.mozilla.org/en-US/kb/unable-install-add-ons-extensions-or-themes#w_corrupt-extension-files

If you have any suggestions please let me know.

Firefox keeps reminding me that updates are available. I download and it says its installing but it doesn't seem to update. I have tried closing Firefox before running the installation but it makes no difference. I am on 125.02 at the moment.

I installed Firefox on a new Dell laptop and imported the bookmarks from FF on old laptp. On my old laptop things are OK. On the new laptop Firefox will ONLY store new bookmarks in the Recently Book... folder, no matter how many times I choose a specific folder from the Location dropdown, even if I only choose Bookmarks Menu without subfolder. Show Editor is checked. I have to manually move new bookmarks from Recently Book..... This is annoying. Can you help? I have not found a forum with this question.

I am having a very frustrating problem that is driving me huts.

Just the other day I was commenting in a text box like this one and I hit caps lock on my keyboard and a little grey box I had never seen before appeared with a locked lock. Then when I hit caps locks again on my keyboard an unlocked locked appeared in the little grey box. But it stays in cap locks and no matter what I do it won't go back to lower case. And when I say nothing shuts it off I mean its doing that on every site I try to comment on. Shutting down the browser does not help. And the only way I can get caps lock off is to actually shut down my whole computer and basically start all over.

You community volunteers are the best and quickest help I can get so I went straight to you for help.

I can open the Chase bank site, but cannot log into my account. I can log into my Chase account using Edge. This may have happened after the most recent update to Firefox. Any ideas how to fix this?
