I shut down my PC without closing the Firefox brower tabs and I started getting this message the next time I re-booted and tried to start Firefox. --- "Firefox is already running, but is not responding. The old Firefox process must be closed to open a new window." ---

I read thru the different support forums and tried various answers/suggestions - no luck. Bottom line, I have uninstalled the browser, deleted all the old Mozilla folders from the machine and downloaded the .exe to try to re-install the browser. However, the installation crashes at about 70% completion and I still get the message listed above. I am running on Windows 10 and the PC is up to date with all patches.

I would appreciate if anyone can help me figure this issue out.

Either I'm a dork or the instructions that I have found are not very clear. I have been trying for several days to transfer my settings from my desktop to a new laptop. I have gone to the %appdata%\mozilla\firefox\profiles page until I'm blue in the face. I transferred a directory called "m80s2e9e.default" from the profiles directory on the desktop to the %appdata%\mozilla\firefox\profiles directory on the laptop but keep getting "Firefox profile cannot be loaded" error. What am I doing wrong? Thanks, Dale Webb

Whenever I open Firefox I'm asked to download impression.link. It's keeps popping up even though I cancel. I've tried saving it to make it go away but each new tab I open in Firefox browser I get the same all over again. Impression.link pops up and asks whether I want to save or run it. I've never had this before and it's extremely annoying as I don't know if it's a threat. Do you know what this is and how do I stop it.

I downloaded and installed the firefox app and nothing happens. No menu. No tabs. The word "firefox" appears in the upper left corner of my screen and a "." appears under the app, indicating that it is open. The screen "blinked" momentarily when I opened the app. I am a longtime user of Firefox and this same thing happened this morning when I opened the app, which I uninstalled, and then downloaded and installed this new app. Same problem.

I have just upgraded to Firefox 17 and found that Norton 360 "Login Assistant" (formally named Identity Safe) no longer works. It does not fill in the username and password fields. It worked very well and did all the right things when I was using Firefox 16. There is probably a quick fix but in the meantime I have had to revert to version 16. Looking forward to the problem being resolved.

Hello- I am new to Firefox. I have it set to update automatically. I noticed it was updating to the latest version today, so I stayed and watched. I had version 3.5.2 (I am pretty sure) but the latest version it just updated to is version 17. Is this right? I am used to version going in order but from version 3.5.2 to 17? did something go wrong?

My 64-bit Windows 7 HP SP1 based notebook was under repair for the past couple of months. So, recently when I got it back, I upgraded Firefox manually to the latest version, i.e. 17. However, noticed that both Version 15 and 17 are listed in the Windows Programs list (Add/Remove Programs list). Can I remove / uninstall Version 15 and leave Version 17 alone, or do I need to remove both and reinstall Firefox 17 afresh ? Is this some sort of a bug in the Firefox installation process ?

For unknown reason Firefox 17.0.1 has stopped downloading pdf's. This was happening before upgrading to 17.0.1, and before upgrading to Mac OS 10.8.3 from 10.7.4. In order to get pdf's printed, I have to copy the links and download them on another browser, such as Safari. On the other hand, browsing with Safari alone won't work because it messes up the various websites' formats, and becomes unreadable. Firefox will also have this problem occasionally, but usually not.

    To overcome the problems I down loaded Chrome and Camino, but they only allow new pages as tabs, instead of fresh windows, so they have just added to the frustration! Since I never had these types of problems before, I can't figure out if it is the browsers, or my OS, but I suspect the latter. Have you had similar reports, and if so, where you able to offer assistance?  Thank you.
