When I upload an image with Firefox, it typically shows a red tint. I've seen similar reports from decades ago so I disabled `gfx.color_management.mode` in `about:config`, but that didn't help, even after restarting the browser and the computer. I disabled a couple of related settings, but that also didn't help. What else could I try?

I just tried to connect to YouTube & get "You're offline. Check your connection." I assume this is due to a DoH connection issue. I can connect in Chrome. My Firefox Mozilla Connection Settings are "Use system proxy settings", though I have set this to "No proxy" in an attempt to fix this - didn't help.

Under Privacy & Security: "Enable HTTPS-Only Mode in all windows", "Enable secure DNS using: Increased Protection" - tried "Default Protection" - no help. Using Cloudflare default.

It has been a few months since I tried YouTube - not sure what's up. It works in Firefox on my phone..

Offidocs has hijacked my Firefox browser making it impossible to read PDF files. I never added it and it does not appear in my extensions list. I've marked "always ask" in the preferences for opening PDF files but to no avail. My antivirus and Malware bytes scans are negative. How can I get rid of this?

I recently sent a lot of tabs from my phone to my computer. However, when I started Firefox on my computer, since Firefox tried to load the content of all sent tabs immediately instead loading them lazily (which I think probably should be the default behavior), it took a very long time for Firefox to display even the tab that was currently selected, and I therefore decided to kill Firefox and reopen it, in the hope that all new tabs would load lazily. Instead, when I reopened Firefox, none of the new tabs where there anymore; it was as if they had never been sent. I would like to get them back, but I have no idea how to. Does anyone know if that is possible and, if so, how?

Upto Firefox v115 this website working fine. after update this website table display right side end. not in position. checked in other browser. working fine in chrome. what to do?. need solution. thank you.

on some websites it says -1 tells Firefox to automatically determine the size of the cache based on your physical disk and setting it to 0 would effectively disable any disk cache entrys.

so are this informations true and if not, how do i still let firefox automatically determine the size of the cache based on my physical disk?

I can no longer request further information on sites where it is possible to click and the result will be displayed. For example: I read a national newspaper on-line. After reading the article I then have the option of reading subscriber comments. When the button is pressed page says it is loading - but nothing happens. If I then switch to Edge - no problem. So I guess the problem does not lay with the newspaper. Many thanks for your help.

I have dealt with this message when searching the web... after a google product search etc., the results populate- then I click on all the top results and I get nothing but this message and the sites will not open:

Secure Connection Failed An error occurred during a connection to www.googleadservices.com. PR_CONNECT_RESET_ERROR Error code: PR_CONNECT_RESET_ERROR

   The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.
   Please contact the website owners to inform them of this problem.

I noticed it's with most "Sponsored" results. Incredibly frustrating.

Please help!

Artifacts on Youtube videoes when hardware acceleration is enabled. These artifacts is not there playing video on Chrome with hardware acceleration. Disabling acceleration removes artifacts, but videos runs poorly. These artifacts also appears in regular browsing. Intel GPU on latest driver. Since it works in Chrome with the same GPU on the same driver, the problem is in Firefox. Artifacts not there when running Furmark gfx burn in. So problem is not in the hardware. Problem still persistent even on numerous updates of Firefox. Windows 11, Intel HD Graphics 620 GFX, latest driver, latest Firefox.

Firefox since 102 or 103 has a giant issues with gifs, movies ect after resuming from hibernation. In the Dev mode there are errors like this:

MediaLoadExhaustedCandidates = no any media can be loaded

Invalid URI. Load of media resource %S failed

Why does it happen only in firefox? Even in FF 120 Windows.

Hello, can you add better support playback on .mp4 videos? Seems with Firefox it's a hit-and-miss with some .mp4 videos that will play and some that will just show "No video with supported format and MIME type found".

All other browsers will play .mp4 videos without an issue but Firefox won't.

If you can provide better .mp4 playback support that would be greatly appreciated. Thanks

Here's one of those videos for an example: https://drive.google.com/drive/folders/1Fv6SdftiCXeYPQOdF17H2JNpwjMu9P7q

Pretty much a URL string like example.com/videosample.mp4

I want to delete all my web certs except for the top seven, which cover 99.32% of current web certs. I specifically do NOT want the EU Cyber Resilience Act to have the ability to insert their certs into my root store, enabling their member countries unfettered power to compel acceptance of their certs.

I tried following https://wiki.mozilla.org/CA/Changing_Trust_Settings, but this must be for an earlier version. I don't seem to have an Options/Preferences window. On the other hand I am pretty old & maybe just can't find it....

Any hints on how to do this?

between this netflix error, this amazon alert, and youtube auto switching to 360p it's become increasingly difficult to access media. i've called netflix about this and they had no idea what the code was and have not gotten back to me with a resolution.

does anyone know what's causing these issues? is it just companies being hostile to firefox specifically or is something wrong?

i've cleared my cookies and cache, i've restarted several times, i've logged in and out of everything. i'm on version 120.0.1

Firefox has always maintained that current tabs will be restored after a reboot of the browser, and indeed that was the case for the first half-dozen years I've been a subscriber. That has not been the case for the past 4 - 6 months however. I have the correct Settings for this, so it is not on my end. Why do I always get a fresh Firefox browser whenever I update the version (which is quite regular lately . . . maybe a new version of Firefox every 3 weeks). Please help.

Machine is Windows 10 with a Logitech wireless keyboard. Latest Firefox browser. Not always but sometimes when using Firefox browser to log in somewhere or enter data on some web site, I'll get an incorrect entry for a key stroke. e.g. I enter a 0 and get a 1. But if I enter a 1 I get a 1. So far the error key has always been different.

I've tested things by launching a notepad or Word document and entering the character and in those all works fine. But go back to Firefox and I get the error again. What I have to do is to close and re-launch Firefox and so far this fixes things. It's an intermittent problem which forces me to keep another browser on the machine and ready. Imagine entering a password when all of a sudden you type 'X' and it gives you an 'E'. Really frustrating!

Is there some way to enable and disable specific config settings , on a per-site basis?

For example, let's say I want to disable right-click hijacking (dom.event.contextmenu.enabled) on turtlesaregreat.com, but use the default settings everywhere else.

The Page Info > Permissions panel has some, but not all the ones I want. Is this somehow built into Firefox, or maybe there's an extension?

Thanks.

FF120 on Sonoma
