Everytime I try to open an html file, I need to first close Firefox. A message with the error message "Firefox is already running but is not responding the old firefox process must be closed" appears, and the file only opens if I select the "close" option. After the first time I do it, the problem stops and the next tries open the files without any issues. If I drag a html file to a firefox tab it also opens normaly, without any issue.

This problem started after I set up more than one profile in Firefox. The issue occur both on the default profile or other profiles.

Based on some advice I found online, I tried two solutions: - Run firefox with the -no-remote option. - Delete the parent.lock file on the profile folder.

Neither solved the problem.

Does anyone had a similar problem? Did you manage to solve it? It is a minor issue, but it happens every single day and gets very annoying.

I uploaded an screenshot of the error message that appears when I try to open the file for the first time. I also recorded a video for more details: https://imgur.com/a/P0Qpz8f

I cannot change the playback speed on YouTube recently (about a week). Videos play without issue but using the option to change playback speed does not affect the speed.

Is it a Firefox problem or a YouTube problem? Anyone else experiencing this?

Sorry if long-winded, just trying to provide pertinent info...


So, when I click on the bookmarks icon, I get the following options...

View Bookmarks Sidebar Show All Bookmarks Bookmarks Toolbar Other Bookmarks

The only one I ever use, the only one I need, is actually the Other Bookmarks folder.

This means I'm at minimum two clicks from my bookmarks, and three clicks from an actual bookmark.


My question...


How can I fix Firefox so that when I click on the Bookmarks icon it actually shows the bookmarks I seek to find, instead of all that other fluff I never use?


It'd be so nice to be only two clicks from a bookmark, thus...


1) Open Bookmarks icon 2) See my bookmarks


Thanks for any help you can provide here, as it is so annoying the way it is now.

My website, www.orthodoxdelmar.org, won't load in Firefox but will load in other browsers. I get a white screen in Firefox. I haven't had a problem with any other website.

I've tried going directly to specific pages on the site. I've exited and restarted Firefox. I've restarted my laptop. I can't find any setting where I might have accidentally blocked the page.

I'm running Firefox 77.0.1 (64 bit) on Windows 10. Laptop only 4 months old.

What am I missing?

Thank you.

since a recent windows update, firefox doesnt acknowledge my normal camera. a few weeks before the update i used a temporary extra camera for a meeting on teams. i normally have meetings with zoom, teams, and a web-based teaching tool. after the update all 3 had switched to the temporary camera, which is not suitable for face-to-face. however zooms and teams offered both cameras and i was able to correct it. however firefox only shows the one (wrong) camera when i access the teaching tool. It does seem to be a browser problem, because the Edge browser does offer both camera. however I do not want to use the Edge or chrome for various privacy related reasons.

I have a whole slew of tabs I use daily and Firefox is set to reload them whenever I restart Firefox. Now with version 78 it tells me it has to reinstall and won't keep my tabs, in other words I have to waste time setting all 200 of them up again. Several times a day it nags me to update and there is no option to tell it to Shut Up. If Firefox can't be bothered to provide smoother upgrades, I can't be bothered to upgrade.

The new version of Firefox has removed the drop-down arrow from the address bar, a feature I use several times a day.

Previously, there was a way to restore this by setting a number of "browser.urlbar" options to "False." However, these are currently set at False.

Please advise. Without the drop-down arrow, Firefox is not useful at all.

Is Firefox slowing my Win 7 down, with all you've been adding? I've started cutting cable so went from Comcast to Frontier. Supposed to be 500mbps with ethernet, with Frontier. It is with my laptop, Win 8.1, but desktop is 172 upload & 105 upload. Even with the laptop it gets locked up often when commenting on FoxNews.com articles. Again, the desktop worked good with Comcast. Don't know what that speed was. Thx, Ross

opening menu=folders on bookmark toolbar opens the menu far far away on another display on Linux/Ubuntu 18.04/Gnome

I'm using FF 77.0.1 (64-bit) [Mozilla Firefox for Ubuntu canonical- 1.0, but the problem has been present for the last 2-3 months over those versions current. When I open a folder on my bookmarks toolbar, the menu pops up on another display. If I just move my mouse down, as if the menu were immediately below the folder link, the corresponding rows on the menu on the other display are highlighted. However, clicking at that point does not select that menu entry. I must move my mouse over to where the menu is displayed, all the way being careful to not move outside of the Y dimension range of that menu (or it vanishes). This does not happen on all folders on the menu, but the ones it happens on vary from day to day. Prior to the version of FF that I am on, it would only happen once to a given menu and then it would start opening the menu where it should. I currently have 15 folders showing on the toolbar and 5 of them consistently misbehave.

I'm on Ubuntu Linux 18.04 using the Gnome desktop/window manager (not Wayland). I am using a Dell Laptop XPS-13, connected to a Dell DisplayPort dock which drives two external displays, on which I usually do all my work. If I drop back to just the laptop, all the folder menus display properly. In addition, with the dock connected and the two external displays, if I move the FF window to the laptop's display, the menus display properly. However, in my use of multiple applications, no application besides FF exhibits this problem. If I open a private session, the problem is not exhibited.

Adding a screenshot example. I had to crop it on the bottom side to fit in the 1024 Byte limit for attachments. On the bottom, you see a black area on the left, which is where there is no monitor. On the right is a portion of my laptop's display (cropped on the bottom). On the top are the two displays, and the portion just above the laptop display is my right display, and left is left.

Hello, I'd like to open url links clicked from any program in a private tab. Firefox is my default browser. Links open in new tab, which is okay. I browse in private mode all of the time, but clicking links opens in normal tab, then it cashes the content, cashes history etc. Most of the stuff (from for example discord) is a one time thing, silly and probably even useless stuff.

Is there a possible way to force windows10 to use "firefox.exe -private" as the default handler to open firefox ? I don't really mind if it opens a new window instead of new tab as long as it remains private.

Thank You for Your time.

"Fastly error: unknown domain: www.ebay.com. Please check that this domain has been added to a service. Details: cache-bos4642-BOS"

Why is Firefox blocking me from my eBay account this is the 3rd different error message in a month! The previous "408" error seems to have finally been fixed. At least it eventually allowed access, this one does not ever since last Sun. AM 6/7/2020 when Firefox loaded an update that knocked me off our virtual video Church service. I had to reboot computer and router to get working again. Have not been able to access eBay ever since. Is there a fix? Why do they keep doing this to us?

I am running Win 7, 64.

All help with this greatly appreciated, and I thank you, in advance.

Bob T., Lowell, MA, USA

UPDATE: Aug. 1, 2020:

None of the 2 respondents solutions below worked. No responses to my reply's to them ever received. As noted in my replies shortly after posting this problem Firefox installed an update, and many more since, after that update the problem has disappeared and I've not had it again. As Ithought it may well have been a software glitch.

I consider this matter resolved and closed.

This morning I got onto my Mac to find that Firefox was not playing my streaming services (such as Hulu), so I restarted the browser to find that all of my tabs, bookmarks, and passwords were completely gone. I cannot recover them in anyway and this is extremely upsetting as most of it was for my grad school work. If anyone has anyway of helping or recovering this information, I would greatly appreciate any help!
