FireFox Tweak Network 1.6 Add ons
Sandeep Albritton
Upgraded to version 101.0 after getting the pop-up prompt and now every site I visit is taking at least twice as long to load and display compared to yesterday. (Even this support site!)
Quick Google search on "reduce CPU usage Firefox" and -- long story short -- unchecking both "use recommended settings" and "use hardware acceleration when available" under Performance in Settings solved the problem.
If you feel your issue is purely related to this build and nothing else... You can change your release channel "app.update.channel" in about:config to beta, developer or nightly to use a newer test release.I have never had stability issues in developer or beta releases.
While that might solve problems for some users, I fear that getting beta releases would potentially make my situation worse, since Firefox is well-known for not having the ability to rollback to a previous version without destroying profile information, etc. The last thing I want or need is to have a problem with a beta release and then be stuck with it until a "real" release (hopefully) resolved the issue.
I think that, going forward, I am not going to click "yes" to the "new version" pop-up unless I have had problems with the current release. Again, absent a miracle and a non-destructive rollback process is developed, I need to fix the problem that version 100.0 created here.
Just thinking about the probability that I will be stuck with slow loading of every site I visit until some future release resolves the issue makes me incredibly angry, but I am going to try not to vent.
I have no issues with this release.Nor any previous release.The latest update I had was a security mitigation. Normally these come with some performance cost.You want to always have updates on, for security mitigations.
Additional things you can do for performance is noscript. [But without script, there will be way more breakage in sites], you can clear and update your ublock origin cache, you can use localcdn to pull more resources locally, rather than from the CDNs. All of these also improve privacy and security.
Personally I use brave mostly now-a-days because it by far has the best features and performance on android for me. Also on Desktop I mostly use Librewolf, but the anti-fingerprinting can break some sites, also some DRM like spotify doesn't work with firefox forks.
I should point out -- again -- that through Thursday, before I installed the update from 100.0.2 to 101.0, none of these sites loaded as slowly as they do now, and every site is loading slower. So I do not believe that any DNS issue is to blame, because I was using the same nameservers both before and after the Firefox update.
The odds of the internet connection suddenly going awry at the exact same time as the Firefox update are astronomical. My mail client is unaffected. Sites that now load like molasses in Firefox load at their previous speed in Opera. Nothing else on my computer that uses the network connection is operating any differently than was the case on Thursday.
It is possible that your firewall or other security software blocks or restricts Firefox without informing you, possibly after detecting changes (update) to the Firefox application.Remove all rules for Firefox from the permissions list in the firewall and let your firewall ask again for permission to get full, unrestricted, access for Firefox and the plugin-container process and the updater process.
Looking at your results, the dns did not provide results similar to mine. This explains the slowness.Just as a test, are you up for temporarily tweaking your dns? If not, then I want bother anymore.Also, have a look at this tool--> These questions are in an effort to not just help your browser issue, but your system setup.Your results should've looked like this... see screenshot
I have to reject all suggestions that it is the DNS themselves (or how my connection accesses them), because if that were the case Opera would not function normally. And to answer the excellent question above, I never "tweak" the DNS as I have never needed to. (BTW, Jon, I do know what a proper DNS lookup should look like, but thanks for the screenshot in case I didn't.) Given that Opera works fine, I'm not convinced that any such tweaking would help.
I did think of the firewall possibly being the issue, but I admit that all I did was look up the permissions and when I saw Firefox was already checked I did not look further. I'm 99.9% sure it's not the anti-malware software as I am still using Windows 7 Professional and Microsoft Security Essentials (since they are continuing to provide daily updates to that even though they no longer support the underlying OS ... talk about your conflicts of interest!). That idea is certainly worth trying and can't hurt, since I know how to manually add it back if Windows Firewall won't do it by answering Firefox's permission request.
Doesn't appear to be Windows Firewall either. Undid Firefox permissions, rebooted, added Firefox permissions back in when nothing would load, rebooted again, internet access normal but still taking forever.
I got to thinking that maybe because my DNS settings are in the router and the PC is set to obtain the DNS IPs automatically that I should check the router configuration. And something worth mentioning happened. When I went to the router's internal IP of 192.168.1.1 in Firefox, it was as slow to load as an external site. And Opera, yet again, loaded the router setup page near-instantaneously. (For the record: The PC running both browsers is using an Ethernet connection, not wi-fi.) So it's not the DNS or anything else "out there on the Net" because I should have gotten an instant load of the router.
There is definitely something about Firefox 101 that causes it to access the router (the internet connection, from its point of view) differently than did Firefox 100 and its predecessors. What that is, I have no idea, because nothing has changed in the OS settings. I am more convinced than ever that there is a setting in about:config that was set in a way in version 100 which prevented the lag, and which somehow got changed in version 101, introducing the lag.
Here is what I am thinking. All of you who have tried so hard to help are likely running Windows 10 or 11, whereas I am still on Windows 7 Professional (and no, upgrading to 10 is not an option here). So if whatever changed in the new Firefox release only affects operation under Win 7, none of you are able to replicate my problem.
Firefox began as a project named Phoenix in 2002, aiming to make a browser that was faster, easier to use, and could be customized more than others. From the start, it was designed with developers in mind, allowing them to add new features and change the browser's look with extensions and CSS. As more people started using Firefox, more developers began making add-ons for it.
Privacy, safety, and letting users have control have always been important to Firefox. It played a big role in moving the internet towards being shaped by its users and developers, not just the big companies making browsers.
The Developer Edition of Firefox came with Quantum, offering tools specifically for web development, like editing visuals, checking network activity, and tracking memory use. The move to WebExtensions made it easier for developers to create extensions that work across different browsers.
Switching to WebExtensions meant Firefox extensions could now work more like those in Chrome and Edge, making it easier to share extensions across browsers. However, this change also meant extensions had less access to the browser's inner workings, focusing more on security and simplicity.
At first, some people didn't like the new system, but it has led to a bunch of new, powerful extensions. Mozilla keeps improving the tools for making these extensions, like the Extension Workshop, making it easier for anyone to create them. This has made Firefox better for everyone who uses it.
Firefox comes with a bunch of tools built right in that are made to help you figure out problems, make your websites or apps run better, and add cool new features. These tools have gotten better over time, giving you more detailed information and more ways to play around with your projects.
The Inspector tool lets you look at and change HTML, CSS, and other parts of web pages while they're live. You can mess with the design, see how things are laid out, and even take pictures of parts of the page.
The Console is like a command center where you can talk to the browser and tell it to do things. It's great for trying out bits of code, seeing messages about what's happening on a page, and figuring out problems.
Extensions are super useful for developers because they make Firefox do extra stuff that helps with building and fixing websites. This part of the guide looks at some of the best extensions out there for doing things like checking code, testing how fast a page loads, and making sure your site looks good on all devices.
In short, Firefox is a good middle ground for developers. It has lots of extensions, great tools for building websites, and puts you in control of your privacy. Chrome is top-notch for how fast it works and its debugging tools. Edge is still catching up in terms of developer features but is getting better.
Improved Debugging Tools - New tools are on the way to help you see how your website is built in 3D, keep an eye on web apps, and find memory issues easier. This means you can fix problems quicker and make stronger websites.
Framework Integration - Firefox will work more closely with popular tools like React, Vue, Svelte, and Angular. This means better tools for finding and fixing issues in these frameworks.
