Hi, I'm having this issue with Firefox where it will try to reload/load all my tabs and my system CPU usage will jump to 100% and in the about:performance page it will show Firefox at 140% CPU usage.
I've tried to reinstall, Firefox. I've also tried removing extensions, as that's where I think the problem might be coming from. But it didn't seem to solve anything. I've also gone into about:config and set blockautorefresh to true, but this didn't help either.
I was able to go into about:performance and extract one of the profile performance for the Firefox system. Furthermore, I however am not knowledgeable about Firefox and or web development and the services to understand and isolate the problem that is causing this issue.
I'm running on macOS, and I've only recently switched to Firefox, as I used to run Arc as my main browser.
Has anyone had any similar issues to this and are there any fixes that might work to prevent this from happening. It severely impacts my work as I'm not able to use Firefox until I restart it, and that would be happening ever 10–15 minutes.

Firefox performance on Vue.js has improved significantly throughout the year. Most recently, we sped up reactivity with Proxy optimizations.

Mozilla’s latest edition of *Privacy Not Included reveals how 25 major car brands collect and share deeply personal data, including sexual activity, facial expressions, and genetic and health information.

I use the Pin Unpin Tab add-on to be able to pin and unpin browser tabs via a keyboard command (Ctrl + Shift + P).

https://addons.mozilla.org/en-US/firefox/addon/pinunpin-tab/

I noticed that this add-on has the permission “Access your data for all websites”. This seems unnecessary. What permission does this add-on really need?

Did Firefox removed saved credit cards recently? I no longer see it in my settings page for Android.

So this Tile Tab extension used to tile tabs properly, but the newer version just splits tabs as window split.
Was there any change in API or somthing that prevented developers from making such extensions?
Would love to see Tab Tiling feature like in Vivaldi, Edge or Arc. As I use sideberry, having split window and sideberry takes half of the space.

The next patch set has landed , bringing the TenFourFox security base up to 115ESR. This includes the usual new certificate roots and update...

due to disability, I need Vimium C - All by Keyboard extension, but it says
"This add-on is not actively monitored for security by Mozilla. Make sure you trust it before installing."

Can Mozilla add this functionality to Firefox so I dont have to install untrusted addon?

Yesterday, my 20ish open tabs acted as normal.

The X to close a tab was only present on the active open tab, with the rest not displaying it.

Today, after I updated Firefox Nightly to Version 119.0a1 (2023-08-30) (64-bit), it reopened and now there is no X to close even the active open tab.

I can't find any setting that controls this, no idea how it happened, but right clicking to close a tab is very cumbersome. Anyone know how to restore the X to close tabs like normal?

If you open a new windows in Nyxt browser, you'll notice that it will have the exact same tabs as the old window.

Same can be done with Emacs when in server mode: frames (windows) do share the same set of buffers.

I think this is a comfy feature, since windows' purpose is - IME - not to logically group tabs but rather only to give multi pane visualization when browsing.

So the question is: Is it possible to achieve this in Firefox?

I found three, Betterfox, arkenfox, & Narsil.

I been using Betterfox for the last week. I been liking it because Betterfox doesn't break sites. Back in the day, I tried arkenfox. But it break some sites I go to. Narsil is a fork of arkenfox.

I’m trying to switch to Floorp right now from Firefox, where I have both the regular horizontal tabs, and a flat vertical list with the Tree Style Tab extension. I use the later a lot, and while I could keep this setup in Floorp, I like that the vertical tabs can be native instead of using TST. However, it just feels weird to not have horizontal tabs. I think I might miss seeing a bunch of my tab titles at a glance with it, but I have to use it more and see how I feel.

So I'm using the same account with as close as possible same settings as in desktop and have synced my history, but on mobile the address bar suggestions are just all over the place. Suggesting me random urls i've visited maybe once over all the stuff I frequent and just completely missing most stuff. I firstly need suggestions based on browsing history secondly bookmarks, no open tabs or anything else.

Using both stable and nigthly I have the same problem. Is it the Android app not able to pull suggestion data from my account history or does it just handle them in a different way, preferring recency over the amount of visit times on a site maybe?

It would be nice to have consistent coloring on the phone.

I know I could use an addon like RunWith to download files to the Downloads folder without it asking where to save them, but I want files downloaded through Firefox the official way. I have “Always ask where to save files” unchecked in settings, but that doesn’t do anything.

Hello,

TLDR: How to open all facebook videos in 1 PIP window, or/and auto-close PIP if video ends, or/and disable autoplay, or/and disable mute or just remember mute state.

I'm watching multiple short videos on facebook (without account) and I have few problems:

Videos are too small, but I can't switch to fullscreen, because I lose position, so I'd have to scroll too much every time, so the only way to have larger size is PIP, but I have the problems.

Another problem while playing videos, they start playing automatically, mute enabled, so I have to disable mute and rewind every time.

When I open 1st PIP window for 1st video, it's opened in large PIP window, but when I open 2nd video, it's opened in 2nd PIP window, next to previous, so I have to manually close the 1st PIP and move 2nd PIP, every time.

Perfect solution would be:

• disable autoplay for facebook videos
• always disable mute for videos, or remember mute state per session
• auto-close PIP window if video ends or open another video always in the same window

I already tried:

• google
• bing AI
• about:config option media.videocontrols.picture-in-picture.allow-multiple set to false and true, restart firefox
• other about:config options for pip

Is there any way to open all videos in the same PIP window and not in multiple PIP windows, using any option or even extension, please?
Workaround could be to auto-close PIP window if video ends.

EDIT: Now I have another problem, PIP button is not shown for each facebook video, even the same length, with the same settings, I tried to switch some about:config settings, change them all to default values, but PIP button is shown just for some videos, it looks random.

Firefox 116.0.2 (64-bit), tested with the Nightly 118.0a1 (2023-08-12) (64-bit), default settings without extensions, Windows 10 22H2 64-bit.

It looks like Chrome is going to add post-quantum key exchange X25519Kyber768 to secure TLS connections, see https://chromestatus.com/feature/5257822742249472

As much as I hate Chrome, I'd like to see such a feature in Firefox too. Any idea if there's a technical discussion/proposal somewhere?

Opera's new 'Tab Islands' feature is very cool and I've wished for such a feature in FF.

Briefly, "When opening new tabs from a webpage, those tabs are automatically grouped together into an island."

https://blogs.opera.com/news/2023/06/opera-tab-islands/

I happen to be one of those bozo users with hundreds of tabs open all the time and I'm always interested in any feature, addon, plugin, whatever that would make it easier to keep my tabs organized.

Anyone know of such a feature in FF?

Is there a way to see how much memory each Firefox Add-On uses? I've tried to look into "about:processes", and "about:memory". The first one tells you the total amount of memory used by the Add-Ons, and the latter gives you a 30,000 page long report that I don't know how to make heads or tails of. I KNOW my Add-Ons are eating up a lot of memory. I want to know WHICH ones are eating up the most so I can know which ones I should maybe shut down. Ideally, I wouldn't shut any down because they are all geared toward productivity. But maybe I can prioritize some over others.

Is there an easy way to view this information? Something akin to the Chrome web browser?
