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.

None of the available migration or restore methods are capable of preserving OneTab data. In every case I have tried, OneTab is missing from the add-ons in my new installation or profile. The only approach which achieved anything at all was to replace the entire .mozilla director under Ubuntu, but even this only displayed the OneTab page and its data on the first invocation of Firefox. Since the add-on was not present, the data was gone at the second invocation. However, repeating this process at least allowed me to export the OneTab data from *one* profile on the first invocation. Unfortunately, this method is completely useless under Windows, as are the recommended approaches of using Firefox sync (with sync turned on for add-ons) or replacing the contents of a newly created profile with the contents of an old or saved one. How can I properly backup and restore or migrate a Firefox installation, *including* my OneTab installation and data?

I have a Mac system that has been on OS X 10.11.6 for a long time, and was switched to the ESR channel when the release channel no longer supported this version. I have finally been able to update that system to something later (Mojave, 10.14.6) and want to restore Firefox to the release channel. How do I do this and preserve all of the Firefox settings, history, etc.? Won't installing a fresh copy of Firefox wipe all that out? Thanks for any help you can provide.

Trying to migrate Firefox profile from Win 7 machine to new Win 10. Downloaded Firefox to new machine, confirmed that it worked, closed it.Using Troubleshooting feature, located active profile in old Win 7 machine, copied to USB stick. Closed Firefox on new machine, navigated to Profiles folder, copied the Win 7 file to it and deleted the existing file. Tried to start Firefox, got 'Your Firefox profile cannot be loaded. It may be missing or inaccessible'. Fiddled round a bit, finally uninstalled Firefox from the new machine and downloaded it again. Got the same error message, now no Firefox at all after carefully following such instructions as I could find. What the f*ck am I doing wrong? A year or so ago I transferred the Win 7 profile successfully to a Win 10 laptop. What has gone wrong now? Any suggestions most welcome.

I have a windows 10 laptop with firefox as the default browser. I do not like windows 10 photos, so I downloaded a older copy of windows photo gallery which I am used to and prefer. This has been working fine until recently. Now firefox saves images to windows 10 photos. I made sure to make photo gallery the default app for all images (jpegs etc.) but it still saves them to windows 10 photos.

Not sure this is the right 'topic' but I just migrated all my info from my old MacBook Air to my new one, and Firefox is acting weird: I can go to various common websites, like salon and npr, but not, for example, slate.com.

Also, more importantly: 1. I can't even get to gmail. When I type 'gmail.com' in the brower, firefox does nothing. Even if I try a serach of 'gmail sign in' that will come up, but the link won't work?

2. Also, like, twitter won't work. Facebook I can get to my page but can click on anything, except if I try to message someone, it takes me to a blank page?

My Chrome browser is working, and my TOR browser as well.

Firefox is my prefered browser. What's going on? What should I do?

Thanks in advance!

Thunderbird uses mbox (single file per folder) storage by default. This is not a good arrangement when some folders grow to 2GB over the year; each backup requires the entire file, and that becomes 1GB and more per day for each of those folders for much of the year, ending at 2GB per day each.

I find some mention and discussion of maildir (one file per message) with Thunderbird (as a plug-in). But most of what I see is ancient history, and a lot of it warned of significant problems and dangers. It was 'experimental' for Thunderbird 60, and nothing said subsequently. I see some success claimed from 2016 (Wilders Security). That's old. The Mozilla Wiki warns of dangers and data loss, last updated 2017. Support Mozilla (undated) says you risk your data. http://mzl.la/1GDeRsp

Is there any up-to-date information? Does it work, reliably? Can I bet my data on it? Or is maildir in Thunderbird a no-show?

I'm using Firefox 78.0.2 and i keep getting notices to upgrade. But the last time I upgraded, Firefox changed the locations of my tabs from below the address bar to above the address bar and also changed the behavior of the address bar. It took me a couple of weeks to find the answers and get things back the way they were. I don't want to upgrade Firefox because I have no idea what it might change this time. Is there a way to keep Firefox from sending me upgrade notices when I don't want them?
