After adding Strongbox, it does not show up in tools and there is no way to use it.

After a long time, I've decided to reinstall Firefox on my PC. Upon installing it, I got the error "Your firefox profile cannot be loaded. it may be missing or inaccessible." I cannot start Firefox.

After looking online, I found this article on the support page: https://support.mozilla.org/en-US/kb/how-run-firefox-when-profile-missing-inaccessible

I tried opening the profile manager, but can't get to it since Firefox won't start. It also is not accessible through using "firefox.exe -P" in the run dialog box.

So then I followed the directions and found my existing profiles.ini which pointed to my profile file. Wondering if it got corrupted, I changed the file extension to profiles.iniold and moved the whole mozilla folder to my desktop. Firefox continued to give me the same error message.

Finally I uninstalled firefox, deleted the mozilla folder under %appdata%, deleted the Mozilla folder under %programdata%, and deleted any mention of Mozilla in regedit. I finally reinstalled a fresh copy of firefox... and I got the same profile cannot be loaded error.

Is there somewhere that I'm not seeing that needs to be deleted to finally get a fresh install? I don't care about the original profile and am happy to start from scratch, but have no idea what I can still do in order to get to that point. Any suggestions on what I can do to completely remove any remnants of the original install from years ago?

Hi, I'm new to TB email program. When I first started using it and sent my 1st email, it did copy my email into sent folder TWICE. It was frustrating. I played with the settings as suggested checked "place copy", unchecked "place copy" checked "other", unchecked "other"; NOTHING HELPED. I do NOT have the copies of my sent emails. I spent sooo much time playing with it and to no avail. Very FRUSTRATING. I donated some money to the developers of TB and deserve better functionality of the email program. Please HELP! Thank you in advance. Paul.

out of nowhere, i can no longer freely browse. I keep getting the message shown below. I do NOT have any add on adblocker. I have uninstalled and reinstalled Firefox browser. Did not help. How do I get rid of this problem so I can use this browser?

I cannot access my Mail.com email accounts. When I go to the login website:

 https://www.mail.com/logout/ or https://www.mail.com

Then I click the "Log In" icon, and the login page fails to load completely. There is no Username or Password entry boxes.

After clicking Log In, the URL changes to this:

  https://www.mail.com/#.23140-header-navlogin2-1

I cleared cookies and cache but the issue remains.

I am able to use and signin using Google Chrome. So the problem is somewhere withing Firefox.

This is important as my business email address is on Mail.com !!!!!

I have installed Strongbox; however, it will not add to the toolbar in the upper right of the browser where other extensions appear. Clicking on the puzzle piece just takes me to the page of installed extensions. Even though it indicates it is installed, I find no way to access this password manager.

I use the most current Firefox on Windows 10.

I am suddenly unable to load Firefox on my desktop.. When I double click the icon, I see the circle spin for about 2 seconds, then nothing happens. I've unnstalled and reinstalled Firefox, but that didn't help. I can access it on my laptop, so it seems smth has gone wrong on my main computer. Any ideas?

Hello everyone! I was wondering if it is possible to have both Firefox and Firefox Developer Edition installed on the same computer and maybe even run side by side. FYI I already have the Normal version of Firefox installed.

Hello to the support team of Mozilla, I had a computer that cannot be reopened due to a virus and Malware. However, I have a bookmarks setting with Firefox that has not been imported. I did not have an account (or at least that I can remember) with Firefox. I just set up one today. I had written that I had an account under the username jackhsiao, but I was not able to log in.

I would like to know if I can import my bookmarks that were on the browser of my computer that I can no longer access.

Thank you,

Jack Hsiao

My issue is that whenever I do a fresh opening of the Firefox app on my 14" MacBook Pro, it immediately opens the App Store in the Twilio Authy app. Can anyone explain why this is occurring? Can someone tell me how to eliminate this problem and has it happened to anyone else?

With multiple tabs open, the "X" close button disappears; in Safari, the "X" appears on hovering, not in FF, so I have to open the tab to close it. It's an annoyance

All New York Times Cooking recipes printed from Firefox 109.0 print with the error noted above (The "end of recipe bar" and "Private Note" heading, which usually print at the end of the recipe, over-print wrapped text at the top of the second page of the recipe obscuring underlying wrapped text.). This error had appeared occasionally in the past, but now is consistently present. I have refreshed my up to date version of Firefox and cleared old print settings. The error shows up on printing to two separate printers and it shows up when printing from a desk top and a lap top computer with synced Firefox, and from a separate lap top with Firefox that is not synced. The error DOES NOT show up on printing with either Chrome or Edge browsers.

NY Times Cooking customer Service has not received inquires about this error and suggested the error lay in a settings issue.

Have others reported this error?

All suggestions will be appreciated.

Thank you, Fred Pintz

So I wanted to read PDFs trough firefox with a dark theme, looked up how to do so online, and people say to change the "about:config" option "pdfjs.viewerCssTheme" to "2" instead of "0", I did that, tried opening a PDF, nothing happend, it was still black text on white backgrounds. Tried closing firefox, reopened the pdf, nothing happened, still white backgrounds. Tried to check if it might have to do with that specific pdf file's config, created my own PDF file from a word document, tried to open it, still white backgrounds. Tried disabling extensions, (which I use four of, UBlock Origin, SponsporBlock, Return Youtube Dislike and Translate this page), didn't work. Tried enabling the option on my laptop, didn't work. Tried a bunch of other stuff and it still won't work. My Firefox version is 109 and I'm using Windows 10 I also don't want to use the console/file edit thing with grayscale(1) invertcolor(1) or whatever it was since it also reverses the colors of images instead of just the backgrounda nd text color.

I am a game developer. I work about 12 hours a day, in Chrome. It is my main browser. When I installed firefox, I was asked to "import" cookies and such. I did. Which has been a terrible headache. All of the bookmarks and everything from Chrome came with it, which I already had in firefox, since I've had it for years. But, I thought since this is a brand new computer that I needed to do that. Fast-forward a couple of weeks and now EVERY time I open up firefox, all 10 million history links are in history.

I use firefox to unwind and watch movies. I don't want 10 million links to work in front of where I left off in binge watching Seinfeld.

I've tried everything and followed instructions and STILL, all history from Chrome shows up in firefox. It is infuriating. AND uninstalling and reinstalling did nothing. The setting is already in the account to import from Chrome to firefox. I've removed addons and extensions as well. Nothing has worked.

As mentioned Firefox, unlike Chrome, does not ask me where I want to download a file on my computer. I have it checked to "Always ask me where to download the file" and yet it still does not. Additionally when downloading PDFs it opens another tab as a preview for the document in question that I have just opened, but I do not want it to it is quite annoying. Thank you for your help.
