Firefox Support Forum

Around 11/26/2022 I guess Firefox updated? Afterward every time I launch Firefox it opens two tabs and goes to the first time user welcome setup. No matter what is changed it will not save and repeats this action again at next start up.

How do I fix this problem? Thank you for your time.

Hi

Trying to make sync work the way I want. Initial question:

I've synced tabs between Windows desktop and Android. Now I would like to bookmark all those tabs in the desktop browser, without opening them first. I've found out how to view them in the side bar, but I see no option to bookmark all tabs.

It would be nice to have synced Tabs in the Library window and Options panel.

I am using the latest version of Firefox with Mojave on a Mac.

Lately I have experienced slowness despite the fact that I didn't add any software and I have Norton checking for viruses. Recently I got a message "Your system has run out of application memory" when I had 5 tabs open in Firefox. I checked Activity Monitor and it showed Firefox using 1.16 GB. 7 other apps were open, the next one with the highest memory usage was Mail (465 MB). Activity Monitor showed 30 instances of FirefoxCP Isolated Web Content entries.

I attached a screen capture showing what Firefox was using in one of these instances. Is this "normal" with 5 tabs open?

I closed the open tabs and quit Firefox. Memory usage by Firefox went down, but after a short time the problem happened again.

A search on the internet showed lots of similar complaints about FirefoxCP Isolated Web Content. Is this a known bug? Any way to avoid this problem?

Thanks.

I have hit "save" when the "do you want to save password" pop up appears many times, but for some reason when I check my logins in about:logins, there is nothing. I tried to manually save a login information with Create New Login, but it tells me "An error occurred while trying to save this password".

MY Windows 11 laptop crashed and OS may need to be reinstalled. Will this wipe out my Firefox browser bookmarks. I would like to save the bookmarks somehow. How do I do this without access to that system?

This is a recent problem, videos don't play after an update to Firefox 107, I've checked and unchecked hardware acceleration, and turned off add-ons. Everything plays fine in edge!! What else can I try

Hi, I planned to block my users from installing extensions/add-ons. I found an article that might be the answer (https://support.mozilla.org/en-US/questions/1308646). I tried to create a simple policy (below), but somehow it does not work (I can still install any add-on/extension). What is wrong with my script? I'm using Firefox ESR 78.11.0 (64-bit) by the way.

My "policies.json" looks like this:

{

"policies": {
  "ExtensionSettings": {
    "*": {
      "blocked_install_message": "Blocked!",
      "install_sources": ["https://addons.mozilla.org/"],
      "installation_mode": "blocked"
    }
  }
}

Sincerely, Jonathan

If I set allowTabDetach to false it still allows it. If I just barely move a tab when clicking on it, it moves it to a new window. In other words, FF is ignoring the setting.

Problem I had two versions of Firefox open. Window "A" (my primary window) had many open tabs. Window "B" had only three tabs open. Like a knucklehead I accidentally closed the wrong window, "A". Upon restarting only the "B" version was there.

Possible Solution Two days ago I cloned my "C" drive as a backup. Although the Profile folder on the backup will only have 90+% of the tabs - I can gratefully live with that. I just need to know what files to copy over from the backup drive Profile folder to the messed up drive's Profile folder. I am hoping it will be that easy and I can copy the tab files and not the entire Profile folder. Thanks.

Trying to create a short cut on the Windows Server 2019 desktop so the shortcut launches a website in Fire Fox without setting Fire Fox as the default web browser. I have tried several ways without success. The server is being used as the master server in a Citrix environment and the users are expecting a near Windows 10 experience in their VDI. Any help would be appreciated

Containers are useful for using multiple accounts/logins in one browser instance. However, Google Docs does not work correctly. Every time I open a Google Docs/Sheets/etc. file in one container, it loads in a new tab in another container. It does this even if I copy the link into a tab with the correct container. I need to keep my Google accounts separated: one is personal, the other is for work. I like Firefox, and use it to get away from Google in other ways. But I can't escape Google because of work and sharing files with certain people. I hope there is a fix for this. Thanks in advance.

Please suggest the schedule for updating new Widevine CDM in Firefox for Browser ( Windows , Linux , Mac) . The current version on Firefox for Windows seem to be still the version released in June 2022.
