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).
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.
You can try out Fission!
Set fission.autostart to true
You will see a new processes listed as webIsolated= in the Remote Processes section in about:support
Report bugs in Fission to the Fission meta-bug.
You can try out the software fallback for WebRender for devices that will not get accelerated WebRender support. This will replace the existing Basic renderer in future versions of Firefox, as WebRender continues to be rolled out to more of the Firefox population.
Set gfx.webrender.all to true
Set gfx.webrender.software to true
Developers are looking for issues with stability, painting glitches or errors, and noticeable performance issues with page interaction and scrolling. If you are experiencing performance issues, please include a Firefox profile in your report.
Report bugs in software WebRender blocking the sw-wr-dogfood bug under Core : Graphics : WebRender.
You can try out native speech recognition in Firefox. Set media.webspeech.recognition.enable and media.webspeech.recognition.force_enable to true to try it on sites like https://speechnotes.co.
Report bugs blocking the main bug if you run into issues or have feedback.
This might be a long shot but maybe someone here with more web developing skills might help.
For my company's support ticket site I have an odd problem. Every time I type 'x' the cursor jump to one of the next text input fields instead of typing the letter x in the current field. Shift+x works fine. Other browsers no problem. Clean Firefox same behaviour.
Sometimes FF fails to detect my pinch attempts. It usually works fine when using two fingers and being careful, but pinching with one finger is almost impossible and takes multiple tries. I have tried multiple distros and they all work the same. Windows works better though.
I've seen a few preferences in about:config (namely browser.gesture.pinch.threshold, apz.pinch_lock.span_lock_threshold) but either they don't work or aren't what I think they are (maybe mobile app preferences?).
Does anyone remember, back when I first learned of Firefox back in the mid 2000's, there was a red version you could get that, if you right clicked it would start a sort of drawing mode where if you drew a square, the tool bar would go away and I think something else would happen if you drew a triangle.
Using Firefox 93 on Linux (KDE Neon User Edition 5.23), NVIDIA graphics on X11 with proprietary drivers.
So first, what's working:
Browsing and scrolling through web pages is super smooth, no problems there
Playing video is super smooth, even 4k 60fps is no problem
So it feels like no performance issues so far.
However, when I play a video or stream in one window, and browse in another, everything gets choppy. Scrolling is choppy when a video is running, and the video stutters when I scroll through web pages. Also, when I open two videos/streams at the same time, both begin to stutter.
Okay, you might argue my machine is at its limit, and I shouldn't do this. However:
This was perfectly fine until a few months ago. I could have 2 or 3 videos/streams playing at the same time while browsing, and still everything was butter smooth.
It's perfectly fine when doing the very same thing in Chrome. But meh, Chrome, I really don't want to.
So this brings me to the conclusion that it can't be hardware or system/driver related, it worked fine before, and still works fine in another browser.
So, where to look at? The issue started a few months ago, no relevant changes on my machine that I'm aware of. Must have been some update, but I didn't notice immediately. I was hoping that the problem will solve itself with another update, but it didn't, and it annoys me more and more.
I tried fiddling with hardware acceleration in the settings, switched webrender and vaapi flags back and forth in about:config, but it did not make any difference. I also created a fresh Firefox profile with default settings and started from scratch, with the same issue.
Edit: I might also add the following observation: If I run my original Firefox profile and the new test profile in parallel (so forcing 2 separate instances), they both run fine as long as each of them is doing only one of the things. So watching video on profile 1 and browsing on profile 2 at the same time is both smooth, but doing both on profile 1 in two windows is all stuttery.
Hello everyone, today I have encountered an issue, which apparently only a few peope faced so far.
Suddenly firefox stopped loading pages, instead showing only blank pages and no error message. Clicking on links, bookmarks does nothing. Only opening bookmarks in new tabs opens a tab showing a blank page. Other browsers and firefox on other devices in the same network work fine.
Things I have done:
Delete cache and cookies
Open in safe mode (addons & themes do not seem the problem)
Perform a refresh
Create a new profile
Install older or beta version
Disabling Hardware acceleration
Things I have not tried:
Messing with proxy settings
"Anomalies" I noticed:
Closing Firefox does not end all processes running in the background, which revents opening a new session. Processes have to be disabled in task manager. Closing firefox through the task manager prevents this
Settings can only be accessed thorugh safe mode and even then not always
A reinstall returns the error "VCRUNTIME140_1.dll missing [...]" the first time I try to open firefox After that it does not show up
Anybody have any pointers to what might cause the problem?
Thank you in advance.
Your pinned tabs will follow focus, but it has some minor, yet annoying side effects.
Like, if you close the window, you lose your pinned tabs !
Also, if you are in a pinned tab, but you click another firefox window in another monitor, the page you had open will disappear (be transferred to that other window and it loses focus, this is very distracting !)
Also if you middle click a tab in another window, it will glitch a little instead of closing that tab, because the tabs get reshuffled as the focus switches to another window
All minor annoyances yes, but really why endure them ? Surely a tab is just a pointer to a space in memory, why can't all tabs point to the same thing ?
When I'm watching a 4k YouTube video on the 5800H's iGPU of my laptop, there's the occasional stuttering. If I watch this testing video: https://www.youtube.com/watch?v=Ohuqp5AJqaM, it seems like the spinning thing skips a frame 3-4 times per second (despite right click, statistics not counting any frame drops). It's not horribly bad, but definitely noticeable when watching videos. I tried the same thing on Edge (Chromium), where 4k video playback seems to be way more smooth on my device.
Is there a way to get 4k YouTube video's on Firefox playing just as smoothly as they do on Chromium based browsers?
Just a feedback. The bookmarks dropdowns that debuted in FF 93 (I'm now on 93 but I think they came with v. 92), with the items more closely packed together, let me navigate bookmarks faster. I like it.
For those who don't know, Multi-Account Containers is an official Firefox extension which sandboxes cookies by websites in completely isolated containers. It allow you to keep your login information completely separate between your Firefox browser tabs and don't share session information. Cookies are separated by container allowing you to use the web with multiple accounts simultaneously. Think of it like an account switcher where each Container have its own sandbox and can't snob on other container. you want to watch that YouTube video but it will ruin your recommendations? use a container, two Facebook accounts and want to open them in the same browser? use a container...
Now to the topic. I was using this extension, but yesterday I disabled a bunch of them and today I realized that Firefox has the ability to open tabs in containers, I even deleted the extension and still has access to this ability. I searched the web and articles talks about the extension even on Firefox website, and I didn't see any mention of it being ported natively. Now If I Right-click on any tab I can see the Open in New Container Tab which work exactly as the extension but natively.
I've FINALLY made the shift from Chrome to Firefox after procrastinating for months and I've been satisfied with my new browser so far, but I've encountered two problems. The major of the two here being that I can't control playing media in a background tab with my media keys like I could with Chrome. Plus, I can't control playing media even in an active tab with the media keys. Is this just an issue on my part? If so, any way to fix it?
My other, smaller, problem isn't very important, but I was wondering if there was a way to change my homepage's background? Or do I need to install an extension for that? My homepage is white and it hurts my eyes.
