Firefox Community Forum

For a long tome Chrome use to be my go to browser, but with all the recent changes and google buckling to legislation changes, I returned to Firefox as my primary browser. You see, because proxy settings can be set within the browser instead of system wide as with others, I primarily used Firefox to access private networks I was given access to. I still use Firefox for this, but mow for everything else too.

I see that there can be multiple profiles set up, which I hope would allow me to quickly swap between proxied connections and non-proxied connections. The problem I ave found, is how hard it was to find this setting with the latest iteration of firefox. It used to be a simple matter of scrolling all the way to the bottom of the settings screen, now I've had to hunt high and low just to find it. Whilst I have mentioned multiple profiles already, if this does not allow me to quickly swap then its pointless. So, can we PLEASE have the proxy page put back where it was, nice and easily accessible,

I use Fireshot on my Mac to take screenshots and normally save as PDF. This works fine using Safari and Chrome browsers. However, using Firefox, when saving the screenshot as a PFD it uses file type 'All files' Up till now, I have been unable to open the file saved as an 'All files' document. But this morning, saving the capture as a PDF 'All files' type, has saved the document as a PDF.

QUESTION: Just using Firefox, why does saving a screen capture uses 'All files' when saving as a PDF. And has the issue been noted and resolved, but the All files file type still shown? NOTE: The drop-down arrow on Format does not offer any alternative.

My hardware is low end from 2016, Pentium 3825U, HD Graphics, and 4gigs of RAM. In the old times, the browser was fast, but this year it has slowed down so bad. I needed to switch to Thorium browser because Firefox became so heavy, using too much RAM and CPU. Please make the browser light, fast, and good for old systems again! (I want to use Firefox back)

My spell check generally doesn't work, but occasionally comes back to life, I have tried the about config, and change value to 2, I have tried uploading dictionary, and making sure check as I type is ticked, but the setting on config seems to keep reverting to 1, and I'm sure if I have successfully uploaded a dictionary, I clicked on language pack, Ironically while I'm typing this, my spell check is actively involved.

I am in China and do not seem to be able to connect to the Mozilla Firefox VPN, to access my gmail (and other features). When I try to turn it on, I get a message: "Could not connect to VPN: Try again in a few minutes" I did this many times. Should I continue trying or is it hopeless?

Thank you

YouTube Has Blocked ALL of current VPN I have been using the Built in FireFox VPN from the start was enjoying the ability of watching YT videos I can not find or watch as I live in the Great White North

is there any planes to fixing FF VPN?

My font on some sites is being forced to this horrible condensed font and it's seemingly nothing to do with my font settings in browser. Thing is, I VAGUELY remember changing a setting SOMEWHERE to actually do this, but it's not the main font setting in accessibility. Furthermore this issue has only started happening in the last day or two and my vague memory of setting my font somewhere was years ago.

Is there any other setting in Firefox that affects default font for certain sites?

[Images attached from terraria.wiki.gg in a normal tab (with bad font) and private browsing tab (with the font it SHOULD have) for comparison]

This device is essentially a thumb drive made by MOPAR that contains automotive serve diagrams for a Jeep Wrangler. When you boot this device with Firefox being the primary browser you get garbage instead of schematic drawings. If I make Edge the primary browser the card boots properly and runs. This a legally obtained card with no password system on board.

The autocomplete dropdowns for form fields have recently changed appearance, and I strongly prefer the previous, simple design.

The new version has:

• Clock icons next to autocomplete/history entries
• Much more vertical padding, making the list unnecessarily large
• Rounded "pill-shaped" highlighting when hovering over an entry

The previous autocomplete list was much more compact and clean, without the clock icons, excessive padding or rounded hover backgrounds.

Is there currently a setting, `about:config` preference or other supported way to restore the old autocomplete list appearance?

Ideally, I would like to use the previous style:

• No clock icons
• Compact rows with the previous amount of padding
• No rounded/pill-shaped hover effect
• Otherwise retain the existing autocomplete functionality

If there is no setting to restore the old appearance, could an option be added to allow users to choose between the old and new autocomplete UI?

Firefox version: - 152.0.1 Release - 153.0 Nightly

OS: - Windows 11 build 26200

GPU: - NVIDIA GeForce RTX 4070 SUPER

Codec package: - Microsoft HEVC Video Extensions installed from Microsoft Store

Problem

Firefox does not expose HEVC playback support, causing Twitch to disable 1440p streams encoded with HEVC.

The same machine can play the same HEVC Twitch streams in Chrome immediately after installing HEVC Video Extensions.

Expected result

Firefox should report HEVC playback support and allow playback of HEVC streams, as Chrome does on the same system.

Actual result

Firefox reports HEVC as unsupported.

about:support:

codecSupportInfo: H264 SWDEC HWDEC VP9 SWDEC HWDEC VP8 SWDEC HWDEC AV1 SWDEC HWDEC HEVC NONE

Troubleshooting already performed

- Installed Microsoft HEVC Video Extensions - Rebooted Windows - Updated NVIDIA drivers - Verified hardware acceleration is enabled - Tested with a brand new Firefox profile - Tested with Firefox Nightly - Confirmed Chrome can play the same HEVC streams

Additional observations

Chrome: - Twitch 1440p becomes available immediately after installing HEVC Video Extensions - Twitch Stats for Nerds reports:

 hev1.1.6.L150.90.0.0.0.0.0

Firefox: - Twitch reports that the browser does not support the required resolution - 1440p remains greyed out - about:support continues to report HEVC NONE

Reproducible tests

Firefox console:

MediaSource.isTypeSupported('video/mp4; codecs="hev1.1.6.L150.90"')

Result: false

MediaSource.isTypeSupported('video/mp4; codecs="hvc1.1.6.L150.90"')

Result: false

navigator.mediaCapabilities.decodingInfo({

 type: "media-source",
 video: {
   contentType: 'video/mp4; codecs="hev1.1.6.L150.90"',
   width: 2560,
   height: 1440,
   bitrate: 8000000,
   framerate: 60
 }

})

Result: {

 supported: false,
 smooth: false,
 powerEfficient: false

}

For comparison:

MediaSource.isTypeSupported('video/mp4; codecs="av01.0.08M.08"')

Result: true

navigator.mediaCapabilities.decodingInfo({

 type: "file",
 video: {
   contentType: 'video/mp4; codecs="av01.0.08M.08"',
   width: 2560,
   height: 1440,
   bitrate: 8000000,
   framerate: 60
 }

})

Result: {

 supported: true,
 smooth: true,
 powerEfficient: true

}

Additional note

Setting:

dom.media.webcodecs.h265.enabled = true

causes HTML5 codec test (https://html5test.co/) to report H.265 support, but does not change:

- about:support - MediaSource.isTypeSupported() - MediaCapabilities.decodingInfo() - Twitch HEVC playback availability

Question

Is this a known issue with HEVC Media Source Extensions support on Windows 11 build 26200, or is there another requirement for Firefox to expose HEVC playback capability through MediaSource and MediaCapabilities when the Windows HEVC codec is installed and functioning in Chromium-based browsers?

I believe that Firefox had a recent update which was auto implemented after-which my entire collection of saved passwords disappeared off of my Desktop computer. Over the next couple or more weeks I reconstructed many of the passwords and was heading back to normal. Today, for unknown reason my entire collection of saved passwords have again been erased and I do not know how and assume they are not recoverable so am back to square one. On my home computer I have it set to not allow auto updates and have a Firefox update waiting and hesitate to allow it, expecting the same result there to my saved passwords. Nothing significant has been done to or with my computer in this same time period so am at a loss as to why this happened not just once but now twice with cause unknown (I am unaware of any second Firefox update in the interim which could have caused this but cannot rule this out).

I tried updating Firefox or testing for the crash in Troubleshoot Mode, but it keeps crashing every minutes or so. Here is the report ID bp-67065b07-74d6-417e-b7de-caf500260906
