I am just posting this here in case it turns out someone here can help me with this because I can't troubleshoot this anymore. Have been doing so for the past day. (Also posting it here in case of the very odd chance that its the adblock (ublock))
I bought a brand new laptop with no OS installed. Installed Windows 10 Pro 1803 from the official Windows iso downloaded from MS website. Activated it with the license I had, installed all the available updates.
Installed Firefox v60, and restored the profile I had backed up from the old laptop. Then updated it to v61, and updated all the extensions.
Now, I expected everything to work as it did on the old laptop, but the following issues have crept up:
1. CAPTCHA doesn't load. When I click the button to verify myself as human, the page just refreshes instead of opening the capchta puzzle.
2. Favicons don't load for some reason. Especially in the newsreader I use, called Feedly.
Both of these seem to be related, from what google threw at me, to 3rd party cookies. But I had disabled 3rd party cookies for the last 4 years I have been using my old one, and this has never happened.
Old laptop was running Win8.1 and Firefox 60. So I am thinking something has changed in Windows 10 Pro or Firefox v61, but for the life of me I can't figure out what.
Any help would be appreciated....I...I am getting too formal....HELP ME GUYS!!
Firefox 61 on Windows 10 Pro 1803 breaks some functionality in the browser.
Update: Ruled out Cookies as the issue. I made a new profile with -no-remote enabled, and enabled 3rd party cookies in there and tried captcha/feedly, but got the same results. It is either some other setting/feature in FF that is interfering or i need to change some windows settings or something.
Sigh... Refreshing Firefox in the alt profile solved the issue...GOD! The amount of individual backups I'd have to take before refreshing/resetting my main profile!!
For backup & restore, I never use sync or copy the full firefox profile folder.and restored the profile I had backed up from the old laptop
what I need to back up
- bookmarks stored in "bookmarkbackups" folder https://i.imgur.com/lA0OW08.png
- passwords stored in "logins.json" and "key4.db" https://i.imgur.com/41XfP6g.png
- the list of the installed extensions https://i.imgur.com/ajXscqR.png
- my custom Adblock Plus filtes hosted on a remote clood server. (dropbox.com, box.com, hubic.com, opendrive.com or bpaste.net)
- my custom FF settings saved on a local text file which i restore via about:config
+1 to what @smed79 said. I backup my settings / extensions / bookmarks to Dropbox. Then put it all back 5-10 minutes tops. Re-using a profile version to version or OS to OS could cause issues all over the place as you have already noticed.
"If it ain't broke don't fix it."
@Lanik & @smed79 : Amen to both of you. Your approaches sound relatively painless, and not too time consuming. Its better to spend 5-10 minutes doing what you do, than backing up the whole profile which takes 1 minute to copy-paste but hours to troubleshoot in case something goes wrong.
