Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Long running tab (kiosk), 100% CPU
Probably your best bet is to use the Firefox Profiler once it starts hogging the CPU to try to see what it's doing. I'd be happy to take a look at the result although I don't have a lot of experience at diagnosing performance problems; hopefully the profile will make it obvious what's going on.

Slow Firefox Startup

Definite tab bug affecting both Win/Linux intermittently
You can try to reproduce while taking a profile using the Firefox profiler, then share it in the #perf:mozilla.org room on Mozilla's Matrix instance.

Why does Firefox run slow
Run a profiling session for ~30 sec when you notice something is running slower than you expect, see https://profiler.firefox.com/. Share results here if you want help interpreting them.

Problems with Firefox non snap versions on Ubuntu 22.04?
Next time, send a SIGABRT to the main process (kill -6 $(pidof firefox)) and use the resulting backtrace (you will find a link to the crash report in about:crashes) to file a bug. A performance profile could be useful, but you'll need to know first what to capture. This seems like a graphics issue, so try the Graphics preset. Share a link to your report.

Dear Firefox, why are you so terrible at rendering Flutter web apps? It's like potato quality.
https://profiler.firefox.com will be useful if you can capture and share it to developers.

Webpages not loading or taking forever to load
If you can reproduce it in safe mode and a clean profile, capture a performance profile using the clean profile while trying to load a problematic webpage, don't remove any information from it, and share it here (although it's typically not easy for users to analyse them), or file a bug with it attached.

Firefox hangs on Facebook page
Next time, capture a performance profile using the Graphics preset, and kill the browser by entering kill -6 $(pidof firefox) in a shell. This will create a bug report (unless debian disables the crash reporter) that would indicate where Firefox is stuck at. You might need to use an official build to get useful results.

Brave's AI assistant now integrates with PDFs and Google Drive
If ads, in particular on YouTube, are the problem, anything Chromium-based is probably only going to get worse and worse (see [1] and [2]). So that basically leaves you with Firefox and Safari.
I work for Mozilla (speaking for myself, of course), so I'll leave you to guess which I'd recommend :P

What are the compelling advantages of Chrome nowadays?
Chrome is working to limit the capabilities of ad blockers:
https://www.malwarebytes.com/blog/news/2023/11/chrome-pushes...
Whereas a compelling advantage of Firefox is that uBlock Origin works best in Firefox:
https://github.com/gorhill/uBlock/wiki/uBlock-Origin-works-b...
Advertising networks have often been vectors for malware. Using an ad blocker is an important security measure. Even the FBI recommends ad blockers:

Brave Leo now uses Mixtral 8x7B as default
> It allows for 30,000 dynamic rules
That is not what we mean by dynamic filters. From https://developer.chrome.com/blog/improvements-to-content-fi...
> However, to support more frequent updates and user-defined rules, extensions can add rules dynamically too, without their developers having to upload a new version of the extension to the Chrome Web Store.
What Chrome is talking about is the ability to specify rules at runtime. What critics of Manifest V3 are talking about is not the ability to dynamically add rules (although that can be an issue), it is the ability to add dynamic rules -- ie rules that analyze and rewrite requests in the style of the blockingWebRequest permission.
It's a little deceptive to claim that the concerns here are outdated and to point to vague terminology that sounds like it's correcting the problem, but on actual inspection turns out to be entirely separate functionality from what the GP was talking about.
> Giving this ability to extensions can slow down the browser for the user. These ads can still be blocked through other means.
This is the debate; most of the adblocking community disagrees with this assertion. uBO maintains a list of some common features that are already not possible to support in Chrome ( https://github.com/gorhill/uBlock/wiki/uBlock-Origin-works-b... ) and has written about features that are not able to be supported via Chrome's current V3 API ( https://github.com/uBlockOrigin/uBOL-home/wiki/Frequently-as... ). Of particular note are filtering for large media elements (I use this a lot on mobile Firefox, it's great for reducing page size), and top-level filtering of domains/fonts.

> "Its happened before"
> That's not an argument
It's a subheading to "2. Browser engine monopoly". The subsection's purpose is describing how bad things were during the IE monopoly to reinforce that it's something to be avoided.
> in fact you could counter-argue that IE left a lot of technical debt
That would be agreeing with the article, unless I understand what you mean.
> On top of that, the internet was very different back then.
In a way that now makes it harder for truly new competing engines to pop up due to increased complexity of the web.
> I'm still not convinced, why would I change my browser?
The points made in the article are:
* Increased privacy, opposed to willingly giving your data to an ad-tech company
* Helps avoid a browser engine monopoly which would effectively let Google dictate web standards
* Itβs fast and has a nice user interface
Onto which I'd add:
* Content blockers work best on Firefox (https://github.com/gorhill/uBlock/wiki/uBlock-Origin-works-b...), doubly so when Manifest V3 rolls out
* Allows more customization of interface and home page
* UX improvements, like the clutter-free reader mode, aren't vetoed to protect search revenue as with Chrome (https://news.ycombinator.com/item?id=37675467)

Ask HN: Is Firefox team too small to do serious security tests?
Advertising networks are vectors for malware:
https://www.cisecurity.org/insights/blog/malvertising
https://www.malwarebytes.com/malvertising
https://theconversation.com/spyware-can-infect-your-phone-or...
So if you're concerned about security then you want the browser with the best ad blocker.
