Nightly Weekly Discussion for Nightly builds for 2022-05-21 - 2022-05-27


Please use this thread to discuss the latest nightly builds.

If you aren't already using Firefox Nightly, you should join us on the wild side. We get the newest features first, and developers generally listen when we give feedback (since they are generally still working on the features, instead of hearing about it months later once it hits stable).

Nightly is an unstable testing and development platform (per Mozilla). Please have a backup strategy for your Firefox profile.

Download Firefox Nightly!

Don't reuse your old profile folder - Firefox Nightly uses different profiles than stable or beta by default, so you can run Nightly and other versions concurrently. You can use Firefox Sync to keep your settings in sync across release channels.

Things to try out in Nightly

Please do not edit about:config unless you are willing to deal with bugs. Please do not post about issues to Mozilla Support; If you have issues, report them to Bugzilla instead.

Elastic Overscroll

You can try out elastic overscroll on desktop (also known as rubber band scrolling) by setting apz.overscroll.enabled to true.

Report bugs blocking the overscroll bug under Core : Panning and Zooming

Native context menus in GTK

You can try out native context menus (also known right click menus) by setting widget.gtk.native-context-menus to true.

Report bugs blocking bug 1757402.

Join our Matrix r/firefox chat room and the Mozilla Nightly one as well!

Solved Android Firefox "add to home screen" keeps opening a new tab.


I have the YouTube homepage added as a Firefox shortcut to my home screen. I'm using Firefox Nightly and was wondering if there was a setting to stop Firefox from opening a new tab every time I click on the home screen shortcut.

Add-ons What addons do I need?


What addons are a must for privacy? (other than UBO, obvio) Here are some that I have considered:

  1. Temporary Containers
  2. Google Container
  3. Don't track me google
  4. Multi account containers
  5. Decentraleyes

I know having too many extensions isn't good, but I don't know which ones to have

Discussion CPU usage on Imgur using 32-Bit version of Firefox. Firefox 100.0.2


32-Bit vs 64-Bit Firefox. Is there that big of a performance difference for media between the two in terms of CPU usage? Or is this a bug in Firefox? Searching, all I could find about the differences were the RAM usage differences. Nothing about CPU usage diffs. So don't flame me for posting about this. This isn't really a help post so I made it a discussion instead.

Recently I had reinstalled Firefox on my newly installed SSD + Windows reinstall. While browsing Imgur a couple days later, my laptop was getting EXTREMELY HOT. I checked temps and they were sitting over 84C. Task Manager showed Firefox was constantly using anywhere between 30% - 100% CPU. I cleared cache out and restarted. Went back to Imgur and it was back to excessively high CPU usage. Many peaks at 100%. I know Imgur is media heavy, but I never had this problem on my old Firefox install.

Come to find out the installer gave me a 32-Bit version of Firefox. So I decided to reinstall with the 64-Bit version. I go to Imgur, I couldn't even get the CPU usage peaks to go over 45% on the same exact pages. And laptop stayed very cool (around 51C - 54C).

πŸ’» Help Firefox website issue - SSL_ERROR_BAD_MAC_READ

I've tried to search for resolution to this error but not seeing anything. In Firefox, a work website I need to get to in Firefox yields the SSL_ERROR_BAD_MAC_READ error. I can't seem to find a solution. Anyone know how to get past this error. The web site works with Edge so it is definitely a Firefox specific issue. Any recommended troubleshooting would be appreciated.

πŸ’» Help Firefox on Mac: a way to add my custom dictionary to Firefox's dictionary?


(On Mac M1 using Firefox 100.0.2 (64-bit) - I'm trying to switch from Safari to Firefox and I need to add my custom dictionary to Firefox's dictionary.

(see attached screen shot) I have all my custom words in a .txt file, but when I go to the "Install Add-on From File..." feature, it says the .txt file is corrupted. Is there a certain format that a custom dictionary needs to be in? Alternatively, where is the location of the existing Firefox English dictionary on a Mac, and is it possible to copy/paste words into that file?

Thanks for any newbie help in switching to Firefox.

Discussion Is Firefox on Linux faster than on Windows?


Firefox is the pre-installed browser on Linux Mint, which I recently installed.

I've always been a Firefox user but noticed that Chrome seemed to be a lot faster. Now, on Linux those performance issues seem to be gone. Does it really have something to do with the OS or was it most likely just an issue with my PC?

Solved Firefox Dev Edition as secondary browser


Is it ok to use the developer edition as a secondary browser?

I'm a Linux Mint user that wants to use 2 separate browsers for work and play. I am currently using two different users, but I find this a bit of a pain switching all the time. I've tried a few forks of Firefox, like Libre Wolf for example, but have experienced broken websites and performance issues.

I've installed the debe v edition using this guide https://tecadmin.net/install-firefox-developer-edition-on-ubuntu/

Would the update process be similar to installation?

Is this a silly idea?

Thanks in advance for any help.

Help (iOS) Anyone else have an annoying blue dot at top left of screen while in Firefox (iOS)?


I’d post a screen record but hopefully this can be discussed without it.

If you click on the address bar, as the screen changes to focus on that, the dot goes away. Once focused, it appears again. Present during all other times (besides tabs view).

Actually just realized it goes away in the same fashion with the keyboard appearing and minimizing. It’s really bothering me! Lol
