Through extensive troubleshooting, I am unable to get firefox to open at all.

I've done a full uninstall, cleaned all user directories, program files / x86, program data, appdata roaming and local, etc. I used the Microsoft uninstaller and even Revo Uninstaller to remove everything related to Firefox, did a restart and reinstall of the latest one and it still won't launch.

Firefox was previously working until a reboot occurred and now it won't launch.

Firefox 32 bit seems to work when installed, and running Firefox as an admin previously worked but no it no longer does.

I looked at the following articles: - https://support.mozilla.org/en-US/kb/firefox-wont-start-find-solutions - https://support.mozilla.org/en-US/kb/profile-manager-create-remove-switch-firefox-profiles - https://support.mozilla.org/en-US/kb/profile-manager-create-remove-switch-firefox-profiles#w_start-the-profile-manager-when-firefox-is-closed

There's no malware on this machine (business EDR on it, even disabled it as a test and it still didn't open).

I was able to launch the profile manager but now I am unable to as the processes launch in task manager and then within 5 seconds they close.

Firefox is not running in the background for any user (I'm the only one logged in after a reboot as well)

I'm unable to open in troubleshoot mode either. Tried run as and admin cmd "C:\Program Files\Mozilla Firefox\firefox.exe" -safe-mode

Ran SFC / scannow / DISM restore health commands as well and both came back fine / no integrity violations

I have been using Easy Screenshot for years. Today I tried taking a screenshot and it opened a huge copy of the rectangular image I wanted to save in a new tab. Then there was no visible way to save the image. I used to get the option to save the image file in the same tab as the image I wanted to save. Took a screenshot and saved in Paint to show the contents of the Firefox window that image is huge and should have been 4 inches wide at most. Also the lack of how to save the image.

I'm wondering if this a because of the latest update. Firefox 147.0.1 X64 desktop WIN10 22h2 with ESU

When I tried reporting the problem on the add-on page the website it tried to connect to was not working so asking here for help.

I am not sure what to do first. I already paid for the VPN subscription. I reinstalled Mozzilla VPN but have not yet put the sudo lines in that are listed in the help on Firefox. Can you send me an email with instructions and any special sudo lines I need to intall so I do not get charged a second time. I heve the recovery code. I am new to Mint. Windows 11 started knocking out my hardware with power surges. Had to come from the operating system itself since the machine is hooked to a power backup that smoothes the current out. Converted everything to Linux. Like it. Life can be cruel... LOL Thanks so much for the effort. [edited] landline, but best bet is email. [edited phone# and email from community support forum]

I searched, and all the internet results I find tell me to look in the settings:applications:mailto ddlb and select Yahoo. The problem is that it's not there.

There is a "use other" but there's no hint on how I'd tell it to open https://mail.yahoo.com.

How do I get it to open Yahoo mail?

This is on W11.

A heart has recently been included in the Firefox icon in my taskbar. What's the reason for it and what do I have to do so that the Firefox icon no longer has it? I've run a number of antimalware programs and they came up with nothing.

how to add Yahoo search as default search engine if Yahoo is missing on Firefox Search. on Search setting i can see different engines Google, Bing, Ebay, etc. but there is no Yahoo.

Three days ago this started happening. When I mouse over the Firefox icon on my task bar, I get a long vertical list of open tabs, the majority of which are blank. When you try to click the X (that appears on the right side of the list when you mouse over a blank space) nothing happens. In the past few days it showed a random mix of blank tabs and open tabs. Yesterday it only showed the open tabs at the top with a long list of blanks below. And today it's only showing the one tab I have active (despite having up to five tabs open before I took the picture).

Before this all started happening, it used to show large tab previews (not just text) that run horizontally along the bottom of my screen when I hover my mouse over the Firefox icon on the taskbar. Now it's just a list that goes vertically with all these blank tabs.

How to return things to normal? (tab previews horizontally without blanks)

I'm running Windows 11 Home, Version 25H2, OS build 26200.7623 and Firefox: 147.0.1 (64-bit)

Thank you, John

I have enabled the option to open the previous windows and tabs. I had one window that I always closed last as it had a lot of groups that are important for my work, so it used to open every time I started Firefox. Sometimes, even if I closed the window by mistake without closing other windows, I was able to get it back by pressing ctrl+shift+n.

But yesterday, I might have closed it by mistake and when I pressed ctrl+shift+n , it didn't come back. I wasn't able to access my window and now it's all gone. I don't see anything in recently closed windows in history.

I need those tabs back as they are very important for my work. they were a lot of tabs. I had many groups but now all are gone. I tried by using the previous.jsonlz4 in the sessionstore-backup by renaming it in the default-release profile as sesstionstore.jsonlz4 but still wasn't able to access my window.

I didn't clear my history as the tabs opened in the window still show up in the history.

Kindly help as soon as possible
