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.

updated Firefox and lost everything, I can get over no bookmarks but what I don't understand is the distortion of the screen, big green blocks and changing letters from letters to blocked out squares making my email look like it has been redacted. How can I fix my Firefox installation to stabilize the font. I tried reinstalling and updated the advanced settings but I don't think that is the issue, it almost seems like a virus.

Hi, as of yesterday I'm no longer able to use firefox, since browsing doesn't work anymore. As soon as I try to load a page, a messge pops up that said that due to a possible health risk firefox doesn't even bother to connect (and of course I looked for a link that allowed be to go on) The test is geman, but I think that the basic of the message. Unfortunately there is no support whatsoever in other languages.

I think I can change the settings in opera, which, as the best browser atm, would be a real improvent to firefox, but I am not able to export the chronic as well as the bookmarks, that why I stayd with FF. But now, since FF isn't running anymore, I decided to finally improve my Browser. How do I import bookmarks,chronic and other settings form FF to Opera ?

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.

When I try to open Firefox on Debian Linux I get an XPCOM error XPCOMGlueLoad error for file /mnt/chromeos/removable/plus_slim/dev/linux/packages/firefox-87.0/firefox/libxul.so: libdbus-glib-1.so.2: cannot open shared object file: No such file or directory Couldn't load XPCOM.

I included a screenshot of the message and my firefox file directory

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.

Microsoft updated overnight and today I can't get Firefox to work at all. Have downloaded/installed 3 times, but it just keeps searching for my bookmarked sites (gmail and comcast.net, for example). I have made Firefox my default browser. Any suggestions? I'm not sure I'll know if someone responds b/c I can't get into my email -- tho guess I could use Edge? I don't like using any Microsoft product ....

Every wednesday I receive a comment from Firefox that my browser software is outdate. Every Thursday i have to reconnec to my addons, etc. Why does this happen so often and do you really update your software every week.

I have installed Firefox as my default browser on a new iMac, but every time I open Firefox (after quitting it or shutting down my computer) it asks me AGAIN if i want to set Firefox as my default browser. If I say "yes", I have to start all over again setting My Yahoo as my home(opening) page and reset all the bookmark shortcuts I've put into my bookmarks tool bar.

I've confirmed in Firefox, in Safari, and in System Preferences that Firefox is set as my default browser. I've uninstalled and reinstalled Firefox.

I have no experience with having different browsers on the same computer and want to know if there are any conflicts or problems before I download a second browser.

Updating to new version of Fire Fox, my home page was changed to eco Start Page and my default search was a yahoo Eco Start Page . Why did this happen? I had trouble correcting this and how can this happen to FF? I thought your browser was secure.
