Firefox Support Forum

Some years ago I had to replace my PC and thought - Wonderful - just use sync to bring back all my tabs etc into the new PC...

The long and the short of it (in the past), was that Firefox decided that the new PC was the one to be synchronising source, and promptly removed all the apps/tabs etc. so sync was in line with the new PC - erasing all the app data. I understand there is no 'Master' sync account.

The question is, how can I stop Firefox initially migrating the Firefox app data in the wrong direction? I know that the app/tab data is currently still correct as my laptop still has all my apps etc. Is there some way to stop Firefox thinking the latest clean browser on the new PC has the correct (None) apps etc? Has the laptop to be logged-in and currently on-line before starting the new PC with Firefox? Is there a process to follow with a new 'un-synced' PC?

Sorry if I'm making things sound difficult, but don't want to loose everything which is currently correct and still these within sync data. It's maybe something that can't happen in these later versions of Firefox, but I want to be sure before logging in my new 'Blank' PC.

EVERYTHING especially

 * The time to receive the first HTTP response when connecting
 * the time to call up the various css elements that make up the screen
 * the time to call up the img elements on the screen
is too slow.

tooooooooo slow. I waited 36.6s until http response for every new URL open! Of course, I am using a lot of Firefox extensions, but there were no serious problems outside of YouTube, and the same problem occurred after removing the extension, and i also confirmed that the problem caused by web extensions on waterfall(on firefox profiler) was minor.

I can't even guess the cause of the problem, so unfortunately there seems to be no additional information that I can give you. I'll keep following up as long as I can. I will attach some pictures that might help you solve the problem. and you can also approach to my full-recorded firefox profiler data

To check my icloud email, I log into icloud.com, enter my password, got through a two step authorization process and ask to stay signed in. I successfully access my email messages. When opening a message that has a hyperlink, I lose the iclolud connection. The link opens in a new browser window, but when i return to the email I am frequently signed out. Apple support does not know what the issue is; they suggested a different browser. This does not seem to happen with Microsoft Edge - and I don't want to use it.

Thanks for your help David Bartold; dwb0224@icloud.com

New tab opens to blank page and not my home page, which is Google. I have been to setting and went to the drop down box for tab settings but it only gives me an option to make firefox my home page or a blank page. I want Google to be what appears in my new tab when I click on the little + isgn.
