Hi,

I frequently have a problem where I will receive this error message every time I try to open a link from another application or the Windows desktop: "Firefox is already running, but is not responding. The old Firefox process must be closed to open a new window."

The existing Firefox window is running perfectly fine with no problems, and I am forced to copy and paste links to open them.

The problem goes away temporarily if I restart Firefox but usually starts happening again not long after.

I did search for help with this problem but the only results I found were in relation to the Firefox process actually being stalled and preventing the application being re-opened, this is NOT what is occurring for me.

I been reading various guide about how to use CSS to override the hyperlink color. But it is not working, Firefox are not grabbing the userChrome.css from the folder. I am not sure if there is other step that I have to do since I did everything to enable it through multiple guides.


  • toolkit.legacyUserProfileCustomizations.stylesheets is enabled
  • chrome folder is created and located in my profile root folder
  • userChrome.css and userContent.css is in chrome folder
  • restarted Firefox multiple times even checking the task manager to ensure that Firefox is absolutely shut down.

Based on those above, it should be working. I thought it was the CSS code, however Stylus have no issue with the code. Yes, there are two empty rules in there because I got the impression that CSS strongly relies on inheritance. So I set this way to ensure that that nothing will be overridden by the website CSS. I created a clean fresh profile and set the same thing above and restarted Firefox. Unfortunately, it didn't work. So the addons are ruled out. my default profile is ruled out since the clean fresh profile having the same issue.

I don't know what is the possible issue of this? I don't know if my CSS is defined correctly since Stylus does not have a issue with it and applying CSS on all websites. Anyone have a clue?

My CSS content:

@namespace url("http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul");

a: link {} a: visited {

   color: #ffa500 !important;

} a: hover {} a: active {

}

Hi!

I want to dump/debug http traffic with mitm proxy: https://github.com/ganskef/LittleProxy-mitm . This proxy generates it's own root certificate which i manually imported to Firefox from about:preferences#privacy > View Certificates > Authorities > Import. I verified that cert shows up after importing it. But I get errors despite of that:

Secure Connection Failed

An error occurred during a connection to www.youtube.com. Peer’s certificate has an invalid signature.

Error code: SEC_ERROR_BAD_SIGNATURE

Is there a way to bypass it?

I have bookmarks in my bookmarks menu list that the bookmarks manger doesn't show. How do I rectify this so that I can manage all my bookmarks? I've read all the "Get Help" sources I can find, but none seem to apply to my problem. Why can't firefox just make all the bookmarks drag and drop, without having to go into the manager, it would be a game changer?

For some reason after the version 87 update, I cannot get any updates for Firefox unless I completely remove my Firefox browser application including all registry entries under Software for Firefox and Mozilla. Then I was able to obtain version 91.0 by installing a fresh copy of Firefox. However, I still get the message under Settings: "Your browser is being managed by your organization". Clicking on that message shows that the policy DisableAppUpdate is true.

I searched the directories C:/Windows/PolicyDefinitions and C:/Windows/PolicyDefinitions/en-US, but could not find the offending poicy DisableAppUpdate. This policy is set to true by the system administrator. I am the only user and have administrator privileges. How can I set this policy to false or remove this policy? I want to get updates!!

Thank you, Peter Nevard

When I type a search query into the address bar and pres enter nothing happens, the little dot symbol just goes back and forth. Tried changing search engine, no change. MS Edge works OK.

I have just moved to Spain, could this be an issue, it never has in the past. Also Firefox updated to 91.0.2 just before I left UK.

I've cleared all cookies, cache, reinstalled firefox, all the usualy things but to no avail.

please can anyone provide a real solution?

Is there a way to determine where the add on saves files? I do not see any way to do this. My preference for "file saving" is "always ask" and I can't seem to add MP4 in the applications box. This is not a problem with Video Download Helper (3 colored circles). That add on allows one to select where things should be saved. Sometimes that add-on does not work but Video Downloader does.

G'Day,

I earlier posted with respect to getting tabs to appear below the address and search bars on the browser. I managed to solve that issue; however, the solution has produced a curious side effect.

When the browser has entered Full-Screen, the tabs-bar does not disappear and appears as it would in a normal browser window while both the address and search bars have been hidden. Is there some way to fix this?

As well, on a Windows 8.1 lap-top, using the CSS below, the very top of the browser has been cut off. It is not possible to see the browser control icons nor is the menu-bar visible.

A screen capture is attached as well as the CSS which was suggested in my earlier post about getting the tabs below the address bar.

Thanks,

Jim
