I can't open Firefox. I keep getting the message "Firefox is already running, but is not responding. The old Firefox process must be closed to open a new window.". I can't find it to close. I tried uninstalling it, but I keep circling back to the same message. I tried refreshing it and again same message. I un installled Surfshark VPN, I ran Windows Defender antivirus. I am now out of ideas. I do have two profiles, but the message about deleting them is scary. I don't want to do anything until I understand what I am doing.

Windows 11; all updates are installed, Dell computer purchased in October, with AMD processor.

https://crash-stats.mozilla.org/report/index/d8249736-7e22-444b-8710-80b0d0260422 this happens when i search on google go youtube chatgpt any page on the web.

I normally have 4 windows open, each with multiple tabs, for 4 work streams.

Whenever Firefox or MS decides to do an update, one window sometimes, 4 rarely, none usually, are recovered after restart. How can I ensure that Firefox remembers all the windows and their tabs before shutting down? Then reinstates them after starting up. After the last MS update, the option "Recently closed windows" was greyed out. But there had been 4 of them.

Firefox's recovery after simply rebooting the computer is more, but not completely, reliable. Win11 on a desktop computer

Thank you

Ok, so I dont use my computer that much, but anyway. I get on it today and this "create a profile" pops up. once I get in to firefox Everything is gone, my history, passwords, bookmarks, addons.

WTF happened???????

as soon as i startup firefox it has a quick flash of white before the background image comes up. it happens on new profiles/troubleshooting mode.

i have tried disabling hardware acceleration and it doesnt seem to help.

Best topic is covered by all of the options, unfortunately! If I have done anything incorrectly it was done thru lack of tech savvy for which I apologize for. I have to go take care of the horses now, thank you for any help you may have.

I can't save my tabs & windows anymore, I have the box checked but after I close down the computer I lose all the tabs when I reopen and then I need to put them all back manually. What has gone wrong it always worked before for many years? Please tell me how to fix it

on my laptop the firefox search engine randomly changes to one that I don't even have checked as "search shortcuts" but are still on my "default search engine" list for some reason (but never chosen by me

I have been using Firefox for years and had no problems. I have it setup for custom URL home page to yahoo. When I go in and try to search anything, it shows about:blank. If i try several times it will work. For testing, I tried google chrome and do not have this problem.

Any thoughts?

Tyhanks in advance.

When I click a link in Firefox sometimes it will open up the new window in Chrome, how can I stop this? I don't want to make Firefox my default browser, as I use Chrome for that.

Someone seems to have messed with the search tab. For better or worse, I use Google most of the time, The search tab used to default to Google. If I occasionally want a different search tool, e.g. Wikipedia, I would use the dropdown list. Now it seems to default to the last used search tool. How can I get rid of this "improvement"?

It seems that most times Firefox does an update, it deletes the Amazon UK search tool and does not provide any option to put it (or any Amazon tool) back. Where is it on the list of search tools?

Hi why have firefox started to close tabs when browser beeing closed? Allready checked the usual sugggestions like open previous, private mode etc. Assuming this relates to an update because have same issue on several computers ( same account)

I have been annotating a student's pdf report online using PDF24. I started last night and continued this morning. Now PDF24 says there is no file. But the completed 5 page file is completely viewable in my Firefox browser. How can I save this as a PDF file? When I try to use the print tool in Firefox, only one page of the file is included and that is mixed up with the PDF24 toping and tailing. The student needs her commented report back.

I run the current version of Firefox on a Dell Inspiron laptop under Windows 11 Pro. I have around 8,000 bookmarks, and I try to keep them current. Every so often, quite a few (about half) of my tags disappear, and I have to spend two or three days restoring them. Why do the tags disappear, and how can I prevent their loss?

What changed to prevent youtube from working? It worked for as long as I have had your browser and two days ago... all of a sudden it doesn't... just freezes. I've done what you suggested... it didn't work I installed an extension yesterday and it worked yesterday... Now today... not working even with extension

help please
