Firefox Support Forum

Hi I updated Firefox and now everything is gone. History Dave bookmarks and paid downloaded programs all gone. I tried everything to recover but nothing

Please help

Graphics card on old Win7 computer running Firefox died. Unable to render image to screen. Setting up brand new Win10 system and downloaded virgin current Firefox. Have hard drive from old system set up as an external device drive and want to migrate years of bookmarks from old Win7 system on external drive to new Win10 system. Can you please assist?

I want to use Firefox, not Chrome, for my information transfers to Centrelink etc. Firefox stalls - stays blank below - every time I expect to get further info when I have filled in data. This is not so on Chrome, where the next step is revealed after filling in a segment of info/data.

Specifically, I am trying to pull up a web-site. It is called - http://pi-star/

Can someone help me with the right settings.

Plus, this works on another computer, but not this one.

The IP address I am seeking is wlan0:10.0.0.100

Please contact me if you can help. Thank you. Rick

Dear Reader:

HELLLLLLLP!

I loaded Firefox yesterday using Firefox Installer.exe

The installer loaded to my laptop with Desktop Icon Target "C:\Program Files\Mozilla Firefox\firefox.exe" This has my bookmarks and personalizations, and is synched with the Firefox on my Tower computer in another room

Now my laptop has another Destop Icon Target "C:\Users\FEDER\AppData\Local\Mozilla Firefox\firefox.exe" This firefox browser is new and has none of my bookmarks and personalzations. It is not synched.

My Apps shows only 1 Firefox installed, and it will not uninstall.

How do I remove both of these firefox browsers, remove firefox from Installed apps, so I can load a clean version?

This is frustrating.

The file you are supposed to download on page "https://www.support.xerox.com/en-us/content/146849" gives a webpage with trash, where it should open the download window . I know it's Firefox because I tried downloading that file via Opera browser and that succeeded . Dowloading zip files from the Xerox website gave no problem, only DEB files .

This has become really annoying: when I go to settings -files and application it is locked to "Downloads" Folder. I want them to go to desktop and then decide what folder I want to put them in (if at all)!

Firefox was running fine but few days ago, cannot get Firefox to start. Tried to uninstall, reinstall but didn't work. Tried uninstall, shutdown, reinstall and didn't work. Tried profile manager but it would not start so deleted the profile.ini file. Still won't start. When I look at Task manager, no processes for Firefox are running. Is there something else I should try to get working or should I just not use anymore?

Lenovo P52e laptop, Windows 10 Pro v22H2, 64-bit operating system Mozilla Firefox 64-bit program is being installed in Program Files directory

I have an mid 2007 IMac running El Capitan 10.11.6 I replaced my old Firefox version with a newer incompatible one and now I can’t recover the old version of Firefox. All my bookmarks and saved data was on that older version. Can anyone help me find the most current version of Firefox for my Mac? Thanks!

Hello,

I received this message when trying to download a file a client sent me. I can download using other browsers but why should I?! ether I get a solution or I'll just change my browser instead of using multiple

Please advise thank you in advance Itai m lustgarten

Firefox detected a potential security threat and did not continue to email.wetransfer.com because this website requires a secure connection.

What can you do about it?

email.wetransfer.com has a security policy called HTTP Strict Transport Security (HSTS), which means that Firefox can only connect to it securely. You can’t add an exception to visit this site.

The issue is most likely with the website, and there is nothing you can do to resolve it. You can notify the website’s administrator about the problem.

Hi,

I am trying to setup firefox to my liking automatically To this end, I am using "firefox profile maker" and it works great but I'm having issues adding all the add-ons that I like.

Only the add-ons that are included in ffprofile make seem to install properly (but also, now I can't uninstall them ??)

Anyway here is my full process for installing firefox automatically and then configuring it automatically. Perhaps you can hep me figure it out.

First I install firefox automatically using the offline installer (my computers do not have access to internet by default, I must whitelist each computer, then individual software then individual websites first)

So, I obtain the offline installer from this URL https://download-installer.cdn.mozilla.net/pub/firefox/releases/111.0/win64/en-CA/Firefox%20Setup%20111.0.exe

Next I have used the website https://ffprofile.com/ to create a pre-made profile

This yields two files, and their contents profile.zip

profile\prefs.js profile\extensions\CanvasBlocker@kkapsner.de.xpi profile\extensions\uBlock0@raymondhill.net.xpi enterprise_policy.zip defaults\pref\autoconfig.js distribution\policies.json firefox.cfg

Next, I have pre-downloaded added all the add-on files I would like to install to the add-on folder However, when I perform the procedure, only canvas blocker and uBlock0 get installed

I'm not sure what I'm doing wrong. If I take all the add-on files, dump them all into firefox, it opens 16 tabs On each tab I can now click add and click okay, if I do it right and quick enough, they all install, unless I miss one.

That's over 50 clicks and very annoying !

Here is the list of add-ons I'm trying to add

extensions\umibo-2.4.2.xpi extensions\amp2html-2.1.0.xpi extensions\close_tabs_right-1.2.4.xpi extensions\cookie_autodelete-3.8.2.xpi extensions\copy_tabs-1.12.35.xpi extensions\darkreader-4.9.62.xpi extensions\facebook_container-2.3.9.xpi extensions\google_container-1.5.4.xpi extensions\istilldontcareaboutcookies-1.1.1.xpi extensions\merge_window-1.0.2.xpi extensions\old_reddit_redirect-1.6.1.xpi extensions\order_tabs_by_domain-0.2.3.xpi extensions\privacy_badger17-2023.1.31.xpi extensions\spoof_geolocation-0.1.1.xpi extensions\tab_manager_plus_for_firefox-5.2.0.xpi extensions\traduzir_paginas_web-9.6.1.xpi

I have created a script that I run after installing firefox using this command

"Firefox Setup 111.0.exe" /S

Then I run the following script to automatically install my pre-made profile

Firefox-deploy-ffprofile.bat

@echo off set z7EXE=%PROGRAMFILES%\7-Zip\7z.exe set EnterpriseConfig=firefox-profile\enterprise_policy.zip set ProfileConfig=firefox-profile\profile.zip set FirefoxProfile= set FirefoxInstallFolder=%PROGRAMFILES%\Mozilla Firefox\ set FirefoxProfilesFolder=%APPDATA%\Mozilla\Firefox\Profiles\

for /D %%i in ("%FirefoxProfilesFolder%"*.default-release) do (

   if not defined FirefoxProfile (

echo Firefox profile is %FirefoxProfile% echo Is firefox running ? If yes, shutdown firefox tasklist /nh /fi "imagename eq firefox.exe" | find /i "firefox.exe" > nul if %errorlevel% equ 0 ( echo Shutting down firefox & taskkill /f /im firefox.exe & timeout /t 5 ) else ( echo Firefox was not running. )

tasklist /nh /fi "imagename eq firefox.exe" | find /i "firefox.exe" if %errorlevel% equ 0 (echo Firefox is still running & taskkill /f /im firefox.exe & timeout /t 5 )

tasklist /nh /fi "imagename eq firefox.exe" | find /i "firefox.exe" > nul if %errorlevel% equ 0 (echo Firefox is still running & taskkill /f /im firefox.exe & timeout /t 5 )

end

echo firefox deployment finished

I wish this process was not so onerous as it has consumed my entire monday :( Thanks

Have been unable to fully load Netflix since the update. Get partial loads which do not work. What loads is a few lines to a few dozen lines of movies. Not a techie. Can anyone help?

I have been using Firefox for well over a decade. Recently, I had to reformat my boot drive, the hard drive C drive.

I lost programs, but not files, as I had done a simple copy of the entire file structure, directories, files, everything, to an external drive. However, I stupidly forgot to export the firefox bookmarks first. So i have a brand new firefox install, but no bookmarks.

Can someone please direct me to where I would go on the external drive to get all my old firefox bookmarks, and the best way to import them into my new installation?

Thank you.

The new Mozilla Firefox (version 110.0) does not run after update on my system. After run it shows the window, but this window doesn't respond. The clean installation (of course with profile folder erase) doesn't fix the problem. I have tried both x64 and x86 versions.

The previous version installation (109.0.1) works fine.

There are some screenshots included. I use Windows 7 on Ryzen 7 2700X processor. Could you please advice, what can be done here?
