Firefox Support Forum

I'm using Nightly (Version 82.0a1 (2020-08-25) (64-bit)) and recently the browser has started flickering. It doesn't come from the add-ons and I tried a full reset without any improvement. The weird thing is that starting in safe mode doesn't seem to suffer from that flickering issue but since I did a full reset it shouldn't be so different ? Anyway, do you have any solution for me ?

Thx.

I have a DNS resolver running on my router, and I had reports from users on my network that after upgrading to nightly 77 they were no longer able to access any intranet domains, I have tested this as well and it would appear that all intranet domains are trying to do search results, this is causing issues as clients(whom I do not own or control their computer) need to access my captive portal prior to gaining internet access and their search fails.

I installed 77.0a1 and CPU usage is through the roof. Nightly used to idle at 20-40 energy consumption units in macOS, which is a lot, but as soon as I updated it jumped to 200, and 150% cpu usage in a 4 core system. The fan is blowing at full speed, and about:performance doesn't tell me anything useful, as usual.

I need to downgrade but I can't find a catalog of older nightly builds.

I am currently using Firefox nightly desktop build. Every day you are releasing 2 updates but there is no clear changelogs for the updates. Same is the case for Firefox preview developer version. Can i have some transparency on the changelogs? Or is it just fake updates released daily? The version number is also same. No change in that. Only date is changing.

Website works on normal Firefox version 70.0.1 and other browsers. I have UBlock Origin as an addon but the website doesn't even load before I have a chance to turn it off to test, I don't think its that. Another odd thing, when I open it in a container (doesn't matter which one) the website will load fine. I've attached my troubleshooting information as well.

Any ideas why this is happening?

If I try to log on to any Google service the tab crashes. There's also some random websites to cause crashes like stackoverflow.com.

I've done the checking of my system with sfc /scannow and it all came out okay as well as doing safe mode and clearing out all my cookies/data.

Here's the crash reports I keep getting (they are all pretty much the same): bp-04470f75-be59-4080-b624-24eac0190303 bp-69e099ef-573c-4dea-b781-8b5900190303 bp-39dec853-e59b-4316-b580-4bae70190303 bp-d6af900e-b87b-4b7f-9d71-d9ab20190303 bp-e9267ab4-c619-490c-88cd-43a6f0190303

Firefox Nightly 67.0a1 (2019-02-27) (64-bit) Windows 10 Pro 1809 17763.316

1) Latest updater fails to update (to 20190-02-28) 2) Latest installer fails to allow a custom location to be chosen

Unless the installer allows a custom location to be chosen, I will no longer be able to use it.

I'm running Neon 5.15 (Linux KDE desktop running on Ubuntu 18.4). I have been running Firefox Nightly. I reinstalled my OS due to a hard drive issue. Now Firefox sporadically fills my network with chatter, preventing other family members from being able to access the internet. I have: tried installing Kubuntu - same issue renaming .mozzilla and allowing Firefox to create a new profile allowing Sync to provide bookmarks, etc. - same issue disabled all addons: extensions, themes, plugins - same issue used standard version of Firefox - same issue

To ensure it's actually Firefox I've been using Chromium (open source version of Chrome) for the past 3 days and have had no issues. I'm using Firefox to write this but have had to close it 3 times due to network chatter.

Please help, I don't want to use Chromium, I want my Firefox back. I've been using it since version 0.5.

As the title says - the post-quantum inofficial fix (linked here: https://support.mozilla.org/en-US/questions/1184503) to move tabs back to the ground will no longer work, when 65 becomes stable. Will they fix it? No: https://bugzilla.mozilla.org/show_bug.cgi?id=1508361 . Why did they: https://bugzilla.mozilla.org/show_bug.cgi?id=1356920 ... no clue at all from that...

Anyone who is familiar with that piece of ductwork i.e. is able to understand what they call documentation, please advice how to get tabs back to bottom again. I tried some things but due to the fact that the TabsToolbar element seems to have completely changed its entire nature nothing worked to change its position. Could not even manage to find out what is the actual kind of container-elements name that now is said to contain the menubar and tabbar.

until today ff nightly was behaving properly on ubuntu 18.10

when I mouse middle click the ff window top boarder ff now fails to lower its window behind other open ubuntu application windows

this behavior worked OK until today

66.0a1 (2019-01-22) (64-bit) Ubuntu 18.10

i am using nightly 65 and when i go to options i set my homepage (is use my yahoo) and it works fine, but when i open a new tab it only give a selection of firefox home or blank page. is there a way for a new tab to open in my home page and if not could this functionality be added? thank you

I was running Firefox Nightly, opened about:profiles and launched a new instance with a different profile from there. At this time, the green update icon indicated there was an update in queue which was then installed right before starting the new Firefox instance, while the old instance was still running. At first everything was fine, my other profile launched, I did my work, closed it and after some more time also closed my main profile. But then when I restarted Nightly, it brought up a Mozilla Crash Report pretty much instantly... My profile is broken

I could work-around this by starting Firefox Beta which prompted me to Refresh the profile... Now I can launch Firefox again, but all the settings from about:config and my extension settings are gone. Is there any way to bring back those settings?

I made a backup of the profile before the refresh so I'm positive the data is still somewhere... However, just copying the profile.js file doesn't work, then I will get the prompt again to refresh my profile...

Ever since Firefox nightly did an update a few days ago, I have been unable to run it from the normal shortcut. I had to make a copy of the exe and rename it and only then would it work from the renamed file. If I click a link in Thunderbird, for example it still looks for Firefox.exe and not the renamed file. If I change the tile to Firefox.exe.bak so that only Firefox1.exe is accessible, I still have to run it manually from that new file name rather than the default. This is a new install of Windows 7 x64 Ultimate and this is the only time I have ever had problems with nightly. Now, when I restart the browser, it downloads a new firefox.exe and the error returns. I would rather try and fix the problem than remove all traces of it then reinstall, that would be like ignoring the problem and starting over which won't 'fix' the error that others might have.

Please see the attached image.

The icon on the dev tools is missing, especially on the "debugger" tab.

My firefox nightly updated last version

Hello! I'm trying to change my new tab page to home page, I tried New Tab Homepage and My Homepage but they don't work. I also can't install New Tab Override. I'm using firefox-trunk (Nightly) 63.0a1 (2018-08-09) (64-bit) on Ubuntu 18.04 LTS.

Also I don't want to use Firefox Stable because he's more greedy than Nightly, I don't know why or if when I test Firefox Stable I have more tabs but when I use Nightly, it's better than Stable for this
