I seem to be encountering various problems since the update to 73, the main one is the profile folder, I dislike the default location so have previously just put my preferred location in appdata\roaming\mozila\profiles.ini but 73 regularly ignores this and puts a basic profile in the default location and alters profile.ini. Using the profile manager does not get any better results. I am also having problems with the home page, I have set a custom page but 73 often resets this to a blank page or sometimes the default home page. I have had to resort to a 'portable' version as 73 constantly resetting things was getting so annoying but the portable does not work well as a default browser.

Hi, We are using a live chat software in our company. Every incoming message triggers a web notification in Firefox. However, the notification window fades away after a few seconds. Is there a way that the notification window stays indefinitely (until the user closes it). Thanks, Chris

My Firefox Developer Edition just required manual help to upgrade to 73.0b2 because the auto-upgrade failed. Not sure if that is important. All new tabs and windows had the "You have to connect to the internet" captive-portal bar across the top, but I'm on a home network without captive portal. Clicking the "go to login page" button went to a "can't find that page" error page.

I tried curl from the command-line of my Mac (10.15.2) and got this:

% curl -v http://detectportal.firefox.com/success.txt

302 Found

I'm prepared to believe that this is ISP-related, rather than Firefox, but on the off-chance that it's somehow down to a misconfiguration of the captive-portal detection servers right now, I thought that I'd report it here.

I've stopped this from happening by setting about:config network.captive-portal-service.enabled to false, but would ideally prefer that this not recur on the next profile reset.

This used to work and works in Google Chrome but not in Firefox.

I know Firefox disabled TLS 1.0 and 1.1 support in recent update. But while visiting site with TLS 1.0 support, Firefox asked me to enable it. I accidentally clicked to enable it. But now I want to disable it again. How to do that?

Hi, I really love everything about Firefox Developer Edition, except the JSON viewer. I'm used to looking at plain formatted JSON like the JSON Formatter plugin provide. But, even thought I have installed JSON Formatter (https://addons.mozilla.org/en-US/firefox/addon/json-formatter/?src=recommended), it only shows this tree/table-ish viewer that comes with Firefox Developer Edition. Is there any way to disable this feature and use a plugin for this, just as in Firefox ?

Hello. I've created a new profile and logined to Sync. Then the sync have start but it can't end. It shows that it's in progress about a hour. I've tried to restart Firefox, restart system with no effect. The log file from about:sync-log is here: https://www.dropbox.com/s/els9dffijyeshuw/error-sync-1580143890286.txt.txt?dl=0

I'm currently on 73.0b5 (64-bit) on Windows 10. I'm trying to use the "Update to 73.0 Beta 11" button from the "About" screen to update the browser. This normally works but today, it's having problems and I suspect it's due to our corporate policies being changed around.

I'm going to submit a request to our enterprise idiot to have this fixed in their whitelists, etc. but before I can do that, I need to know what kinds of permissions to request. What's responsible for the update process and what folders need to have which permissions for this to work?

Because right now, pressing the "Update to 73.0 Beta 11" button results in Firefox downloading the update but when it tries to install it, it fails with the "Update failed. Download the latest version" message in the "About" screen (when it was working last week without a single hitch).

According to my about:support details, I'm seeing the following:

- Update Folder: C:\ProgramData\Mozilla\updates\<Long String> - Application Binary: C:\Program Files\Firefox Developer Edition\firefox.exe - Profile Folder: C:\Users\<my username>\AppData\Roaming\Mozilla\Firefox\Profiles\<string>.dev-edition-default - Antivirus, Antispyware, and Firewall are all governed by McAfee Endpoint Security (which hasn't been an issue in the past).

I suspect that all of this is due to our enterprise guys modifying the permissions that our "elevated permissions" has... So once I have a better understanding of what things need which permissions, I'll be able to request that the elevated permissions be modified accordingly.

Any insight into this would be appreciated. It's a shame we don't have logs that clearly explain what folders or files lack whatever permissions to better understand bottlenecks like this. Maybe we do have that and I'm just not aware of it?

After all recent updates (including the one today 1/29/20) a new window opens informing me that settings for Ad Block Plus for Firefox have been deleted. I get a message which states, in part "It seems that an issue caused all filters to be removed and we were unable to restore a backup. Therefore we had to reset your filters and Acceptable Ads settings."

I am unable to make any payment on firefox developer edition I keep getthing these error messages

Firefox Developer Edition prevented this page from loading in this way because the page has a content security policy that disallows it.

pls tell me how to fix it...

Windows 10. Upgraded, as recommended by Mozilla, to FF 73. Disastrous. Not one web page will load, including any involving Firefox; thus, suggestions to do blah blah via about:config, or ANYTHING ELSE INVOLVING ACCESSING A FIREFOX WEBPAGE is worthless, since Firefox 73 will not load any web page. I uninstalled. Installed 73. No help. I now have "Old Firefox Data" on desktop, but it is useless, since requires pasting to something in Firefox 73. What a diabolical Catch 22 or 23 or something.
