Firefox Support Forum

Hi.

Firefox is very slow. If i do the same browsing, in Chrome, there is no problems.

Reinstall Firefox, and all the guides, is tested - no luck.

I really love Firefox, and have used it, for many years, but this slow experience - that will scare me away.

Roboform not working with Firefox version 110.0 on Windows 11. Works on Chrome and Edge. I've always preferred Firefox, but I'm very dependent on Roboform, so I'm migrating to Chrome until Firefox is able to see Roboform.

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\

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

In Ebay - Print invoices link opens print preview window inside page -> I can view document (invoice) then click print button to open print window -> window opens but the document is blank, just a white page, no text. If I click print, it just prints a blank page. I can download the document as PDF from print preview page and this prints ok but I can't print directly from the ebay page. This only happens in Firefox. Works ok in Edge and Chrome. I have uninstalled Firefox including profiles etc and re-installed, problem still exists. I can print shipping labels via Ebay just not invoices. No issues with printing anything from any other ebay page or other websites.

How do we contact customer service with trouble shooting issues? It is unacceptable not to have a number to call or at least a chat function to talk to a live specialist

The problem is that every time I try to do a search it makes me prove I'm not a robot. There is a message : "Our systems have detected unusual traffic from your computer network. This page checks to see if it's really you sending the requests, and not a robot. Why did this happen?"

When I click on "Why did this happen" I get this:

"This page appears when Google automatically detects requests coming from your computer network which appear to be in violation of the Terms of Service. The block will expire shortly after those requests stop. In the meantime, solving the above CAPTCHA will let you continue to use our services.

This traffic may have been sent by malicious software, a browser plug-in, or a script that sends automated requests. If you share your network connection, ask your administrator for help — a different computer using the same IP address may be responsible. Learn more

Sometimes you may be asked to solve the CAPTCHA if you are using advanced terms that robots are known to use, or sending requests very quickly. "

This is happens on my Lap Top PC, I only have it on once in a while, I usually use my desktop and no problems with it. I have done all the recommended things, like clearing cache, delete all cookies, used Troubleshoot mode, did a install refresh, etc . All with no luck.

Any help would be appreciated.

Dear Firefox Your browser is generally excelent. But you MUST immediately fix your problem with the danish Mitid access. Every dane uses Mitid acessing banks, public websites, healtcare etc etc.

If I click on any "mailto" link the only options are Gmail or Firefox.

If I go into Settings and choose applications then content type: mailto the same options are there- nothing for Yahoo Mail.

It used to be there, now it has gone.

Using version 110.0.1

Is there any way to manually add Yahoo mail to Firefox?
