I can find no recent documentation on command line options for the Firefox Browser. All of the information on this appears to be out of date or just does not work any more (in the latest version June 2021). Is there any documentation on this anywhere that is correct for the current version of the browser? I am specifically trying to run firefox with command line options on Windows 10 but I do not see that that should make any difference. The only option I can get to work is starting firefox with a specific URL; even then I have to change the browser settings to get that to open a new window; because the browser settings override the command line option -new-window

For about a month, google products on firefox randomly stop working.

- I get the "Oops...error #001" in gmail, when i reload it just continues to get an error cycle until eventually it goes to network protocol error.

- Google search randomly does not work at all in the url/search bar, and once it doesn't work the tab is useless. Putting in another URL and hitting enter it appears to have loaded but of course nothing has changed.

- I have no extensions installed.

Referencing these threads: 1281774 1307368 1317055 https://support.mozilla.org/en-US/questions/1333680 (I posted a reply to this thread, but I can't view it and the moderator has apparently closed it thinking this problem has gone away)

We can ascertain that NOTHING seems to help this condition. In fact these threads apply to me as Win 7 / 64 bit apply to me. This started probably about 1.5 years ago.

I too have this problem and yes, it is random. BUT once locked in with this condition, it may "get stuck" for another 5 attempts for the same link. BEST Example, I do surveys every Friday and Saturday night. I use my netscape (AOL) email account. At random, while clicking on the survey link the tab will come up blank and no matter what you do, you CANNOT get this tab to do ANYTHING. No reload, no clicking on a new bookmark, no clicking on home, or typing in the address bar and pressing enter on THAT particular tab. How often does it happen? Maybe 12 times a month (during survey time: maybe every other weekend).

One step further on this. My wife's account on the PC actually does this on a DAILY BASIS REPEATEDLY EVERY DAY when she opens FireFox. In her case, it can ONLY be solved by closing and reopening FireFox after waiting like...say...2 minutes after previously opening it? I have tried opening new tabs etc as mentioned above (including the old right clicky trick and using the "Open in new tab" function). Kinda silly when you have like 27 tabs of blankness. Considering it is her account on the Pc, ok, maybe the "refresh" function might work on her? BZZZT! Nope.

Current version. I can attest that a PC at my 2 jobs that both have Win 7 and at least one, if not both, have 64 bit versions and do NOT display this malady. Also, I did re-install FF about 2 years ago for some other problem. I just ran the troubleshooting more...no go. Per this lead, try https://support.microsoft.com/en-us/topic/the-latest-supported-visual-c-downloads-2647da03-1eea-4433-9aff-95f26a218cc0... and guess what? No such help . Anyone have have something to kill this bug?

I have had a single Firefox Account since 2018. I have updated through three primary email addresses: let's call them 1, 2 & 3.

July 2020 - I changed Firefox Account to primary email 2, and removed primary email 1.

August 2020 - I registered for Firefox Monitor. I added many "another email" (the maximum number, 10 I think) to be monitored : let's call them emails 4-13, and set "Send breach alerts to the affected email address".

December 2020 - I changed Firefox Account to primary email 3, and email 2 is my account secondary email.

April 2021 - I received an email to email 4 saying it was in a breach.

Today - on monitor.firefox.com it says I am not monitoring any emails except my primary email 3, and have not been in any breaches as pictured.

Therefore, there is a bug with monitor.firefox.com: - On the one hand, email 4 (and presumably 5-13) are all still being monitored. - But on the other hand, monitor.firefox.com states I am not monitoring any other emails.

Could a Mozilla dev please get in touch to look into this specific case?

A few months ago, probably after FF update, the "open with" stopped working, only download is possible.

Particularly, simple url links fail to "open with" including reading with firefox itself. I can not open PDFs, outer program links. Only a few PDF links are opened at specially crafted websites. Probably those are sites with on-site defined MIME or allowing the PDF contents being pre-cashed.

In all the other cases where the file being opened should be pre-downloaded with FF downloader, it fails to download. The same file is downloaded easily when choosing "save as"

I guess, the problem may be in the "downloader" part only, since other online contents are displayed, i.e. streamed, or stored in cache without problems.

Hello and thanks for your attention.

I have problem with Firefox and Thunderbird after new Windows 10 installation. I receive "Authentication Required" window, one with "User password Manager to remember this password" checkbox and one without it. I enter my username and password and make sure checkbox is checked. Proxy works perfectly but after program reload i receive authentication windows with empty username and password inputs. I solved this problem in Firefox with FoxyProxy extension but I can't solve it in Thunderbird.

I also have KeePassXC. Tried to delete it but this doesn't help.

I'm trying to remove some old usernames from appearing in the dropdown box when clicking on it. Sites that use a username rather than an email (Steam for example).

I've searched and tried delete, shift+delete, function+shift+delete, etc., etc.

The usernames do not appear anywhere in the history, the saved passwords and logins, etc. I'm at a loss.

Not the end of the world if I can't remove them, it's just frustrating as heck. Any help is appreciated. Thanks.

I use this extension in Firefox on my home PC with no problems. However, when I try to use it on my work PC, Firefox won't load any web pages until I disable the extension - which is very frustrating. No doubt there is something different in settings which I am unaware of which is preventing the pages from opening? The other extensions which I use, AdBlocker Ultimate & Facebook Contaner, seem to work fine on both PC's.

Hi all,

First time posting here, I've been using Firefox for years with no problem but over the last year or so (I can't remember exactly when) firefox starting taking longer to open.

It's not taking forever, only like 6 seconds, but it used to be instantaneous, as every other program on this pc is and it's bugging me. The window opens immediately but it's all greyed out, nothing loads and the blue mouse wheel spins above it.....again, only for 6 seconds. Specs: i9-9900k @ 5Ghz 32GB RAM Windows 10

I've tried every step in https://support.mozilla.org/en-US/kb/troubleshoot-and-diagnose-firefox-problems this guide, no effect :-(

1) As of Sept 9, Windows will not launch firefox.exe, either by clicking on the filename or clicking on a shortcut to it. It says there's no protocol - see attached image. However, if I rename firefox.exe to something different (firefo.exe), it will launch from clicking on the filename and clicking on a shortcut link.

2) In addition, In Windows settings, Firefox is set as default for file types http & https and for browser. Clicking on any http or https file or link ends up with the same result (see attached image).

3) In Firefox settings, Firefox doesn't recognize that it is my default browser. Each time Firefox is launched I receive the message that it isn't, I select to make it, and it remains as if it is not my default browser (see attached image).

Ran admin command scannow /sfc. Errors found and fixed, without resolving the above problems.

Uninstalled Firefox, reinstalled without resolving the above problems.

HOWEVER, if I select Edge as my default browser, Edge allows itself to recognize that is my default browser and will launch any http & https link, as well as open itself when I click on the Edge executable file.

Any ideas how to correct this behavior in Windows 10?
