I have just updated to Firefox v134 stable release on Android and now when I log into github.com, the webpage is glitching and not being rendered properly. The avatars on github look torn and they are blinking when I scroll up and down. This is occurring with current Firefox stable, beta, and nightly releases on Android.

My device is a Samsung T813 tablet running Android Nougat (Android 7.1).

I should also mention that Firefox v134 on Android is also showing UI glitches when viewing the settings in certain extensions, like FoxyProxy. Although, I have also done a clean install of Firefox v134 with no extensions installed and the webpages like github and still showing the rendering problems mentioned above.

Recently decided to try Mozilla for Windows. There is such a problem, and only on Mozilla: the video is very overexposed, the brightness is high, like in a fog, and on all video services, including YouTube. At the same time, I checked on all the other 3 browsers - everything is fine with the video. I did not change any settings in Mozilla, everything is by default. How to fix it?

Hi there,

I am using Fennec from F-Droid (build 1340020). I noticed that many Brahmic scripts on webpages are shown as boxes. I don't recall seeing this in early versions maybe years ago.

Notably all major scripts in India like Devanagari, Tamil, Telugu can not be rendered. However, Odia and Sinhala scripts are shown fine. Outside India, Tibetan script cannot be rendered either. However, SEA scripts like Thai, Burmese are fine.

Moreover, if I copy these boxes to the search bar, the actual content can be shown. The tab view can also show the title of the webpage correctly in Bramic scripts. And if I change the locale in the settings, the UI of Fennec app can also properly display the scripts.

To further debug, I went to the about:config and search for fonts. Unlike western or CJK scripts, the value of font.default of Bramic scripts is serif rather than san-serif. The default value of font.name-list of these Bramic scripts are just Noto Sans or Noto Serif. I tried to switch between serif and san-serif but got no luck.

I was wondering how to fix this issue. Thanks!

Hello,

This new version of firefox. I am experiencing icons grey out whenever I opened a new tab. Is anyone experiencing this below?

Firefox Nightly (next generation web browser test) has no animation delay when playing sprunki, but there is a bug in the beta and current versions that become delay. (That's why I use other browsers.) There is no delay in other browsers. I hope it will be fixed.

Hello !

I recently got a new laptop (Lenovo Legion 5 I think) and while it's been working great, I've noticed a glitch that's happened a few times now. It's usually preceded by the image having some weird line pattern, I haven't been able to take a picture of it but it's almost like the pixels have been shifted ever so slightly. After that the screen sometimes splits strangely (see image). I don't know if this is a hardware problem or a Firefox thing but the only time it has happened was when I was on Firefox so yeah...

Since updating to version 135.0.1 last night, all kinds of interactive maps have been loading like the pictured attached below. Even maps in pdf aren't properly loading, loading black pages. Everything works completely fine in all my other browsers.

I browse using full screen in Firefox. After closing the app and reopening, the browsing window is just 1/4th the size requiring me to expand it, every time. Is this a bug?

After letting Firefox idle for a bit (like 5 seconds) and nothing playing on the screen, when I come back, it causes screen stuttering for my whole desktop. Disabling hardware hardware acceleration doesn't help much.

OS: Arch Linux x86_64 Kernel: Linux 6.14.5-arch1-1 Display (CMN1521): 1920x1080 @ 144 Hz in 15" [Built-in] WM: Hyprland 0.49.0 (Wayland) CPU: 12th Gen Intel(R) Core(TM) i7-12700H (20) @ 4.70 GHz GPU: NVIDIA GeForce RTX 3050 Mobile [Discrete]

I think this is some kind of bug. Every time I click a link in a email, FF comes up half screen on Samsung Tab 7+. This is extremely irritating. I have uninstalled and reinstalled ff with no change. Can't find any setting in my tab that could be causing it either. Any clues?

I've got a Samsung S23, bookmarks no longer display properly on my phone screen while adding and editing bookmarks.

I can only see them in full on my S7+ tablet because of the bigger screen. Is there a way to fix this for the phone somehow?

I used to be able to bypass this by reinstalling, and it's happened within the last 6 months, but now it won't resolve and it's really annoying.

Starting 4 or 5 days ago when entering https://bluehost.com in the URL field, the landing page for Bluehost stopped rendering properly. I cleared ALL browsing data without fixing the problem. Trying to open Bluehost in a private window did not fix the problem. Only opening Firefox in Safe mode solved the problem. After opening in Safe mode, I disabled performance enhancement including hardware acceleration - problem not fixed. The Bluehost landing page renders properly in Chrome, Edge and Opera.

Hi,

I am using firefox 136.0 (64-bit) and trying to access a private Confluence webpage. I noticed that for this specific Confluence page Firefox doesn't display the entire page, instead a big portion of it is not displayed, so I can only see half of the page.

If I go to edit mode in Confluence I can see the entire page, but sadly not in standard read mode.

This is, in edit mode I have a COnfluence Section, inside it I have some text - titles, paragraphs, images and macros. But once I leave edit mode I can see that the page isn't full loading as I can only see some part of the section in read mode (not all).

I am getting this warnings in the console:

I tested it in some conditions in brave and in edge and the full page is displayed.

Any as any idea why is this happening? Or what might be causing this?

I have no extensions loaded and I have disabled enhanced tracking protection.

PS: I believe this is an issue as something to do with macros.

The issue it's also reported here: https://jira.atlassian.com/browse/CONFSERVER-88208

Sometimes in January/February, I noticed that most webpages appear zoomed in on my Google Pixel 9 Pro running on Android 15. I have tried toggling on Desktop mode to view content that runs off the screen, but this is not an ideal workaround. This issue might be related to a recent Android update because I noticed many display changes on my phone across multiple apps in January. I had hoped the recent FireFox update (version 136.0) would fix this issue, but it didn't. Text will overlap or run off the page. If I turn my phone sideways, the content will usually render correctly in landscape mode. But I normally use portrait mode, so I would appreciate this getting fixed.

On a website I visit, Firefox is not showing icons. The attached picture shows how it looks in Fifefox on top and Edge on the bottom on the same PC. Things I have done so far:

1) Cleaned cookies and cache 2) Turned off all extensions and virus program 3) Turned off hardware acceleration

I encounter a problem with the font rendering of some websites. The problem is similar to [one], however I am on a recent Linux distribution (Fedora 41).

Firefox: 137.0

When browsing, as an example, [OpenMediaVault forum], the Montserrat font is rendered as "thin" (weight 100), even if the style mandates a weight of 400.

The font is rendered properly when Firefox is loading the font from the website (in woff2 format).

If the font is available locally, then Firefox does not scale it and defaults to "thin". Using "Inspect", the weight slider appears but moving it is ineffective.

Now, Fedora ships by default with a non-variable release of Montserrat. However, even replacing it system-wide with the variable version (ttf, in case it matters) taken directly from the Montserrat upstream repo, Firefox still fails to scale it.

Any troubleshooting help would be appreciated.

When I click on any of my Instagram photo posts, I only get the background transparent gray screen but no post photo enlargement with comment and 'insights" link section. It does work correctly on other users' accounts. So am I asking the right entity here or is it a Microsoft problem? Thank you.

Hi all,

I would like to know if this color issue is expected behavior or a bug somewhere on my system.

I am using a monitor (Acer ET322QK wmiipx) which displays color at a depth of 10 bits per channel (for a total of 30-bit color depth). When viewing images which have color depth exceeding 8 bits per channel, color banding is visible in Firefox that does not appear in GNOME Image Viewer, indicating that the image is not being displayed at the correct color depth. I've attached an image with 16 bits per channel color depth as an example. This sphere render is deliberately dim to make color banding more obvious. It should look smooth/unbanded on a display with support for colors with greater than 8 bits per channel.

By opening the Firefox console with Ctrl+Shift+K and entering "screen.colorDepth", I have confirmed that the display is identified by Firefox as having 24-bit color depth.
