Diễn đàn hỗ trợ Firefox

I installed an OBS plug-in for a virtual camera so that I could film my screen and pretend it's a webcam. I was able to use the virtual camera or my webcam on spelltable.com by selecting either from the dropdown "allow" menu. One day, I was no longer able to select my webcam. I could only select the obs virtual camera. I switched to MS Edge which worked as normal. I've uninstalled OBS and all plug-ins. Same result I've reinstalled firefox. Same result. I've been using MS Edge for websites that need my camera.

When I close firefox while it's in full screen, turn off my laptop, and then open it again the day after, it opens in the small screen for some reason. I tried going to the root directory in the about:profiles section of the more troubleshooting information section and renaming xulstore.json to xulstore.json.old, and each time it worked for a few days and then it just installed a new xulstore.json and went back to opening in the small screen. This is really annoying and I don't want to switch it manually every time.

Hello. I have a pretty big sprite image i am trying to display on my web page but mozzila wont display it. The sprite is 78016px by 1000px and im cropping it to be 736px by 1000px. Sprite is made out of a png sequence that was made in 3d software, now the thing is when i put in the non rendered verson of images(3D viewport colors) which windows labels as 8bit (maybe because of less colors) it gets displayed, but when i put the rendered version which windows labels as 32bit image it wont get displayed on Mozilla. It gets displayed on Chrome and Edge without any problems. The only difference beetween the images is that the rendered version has a transparent background behind the subject...they are the same sized sprite. I will drop the first frames of the sprite in the images section so you can get a better idea. Also all of the code and images is stored locally.

When I click on the link for Hyperallergic Magazine, the page doesn't load. I don't have it blocked in Notifications. I have allowed pop-up windows for it. I can't figure out what else might be preventing it from loading. It is free. I don't have this problem with any other website that I know of. I'm running the latest version of Firefox & have Windows 11 on a one-year-old PC. I didn't have this problem in my old computer, which ran Windows 7. Please help. Thanks.

I think with the update to 125, I no longer see the typical Windows window controls in the upper right - minimize, maximize, close - so I don't know how to do those things.

THe top right looks like this Mac-based image (where those buttons are on the upper left) but I'm running on Windows so I don't have the dot buttons on top left nor the Windows style min/max/close at top right.

What do I need to do to get them back?

I see my original question is now archived at https://support.mozilla.org/en-US/questions/1380948#question-reply I never closed it because I didn't know if my last process could really fix the issue. It didn't, not always. Over the years, there have been times when the issue would still pop up, but not as often as before (2022 and earlier).

I have a feeling that during an issue, FF is having difficulty setting up shop after starting up. Consequently, it is spending more time before it could become prepared to connect to the Net. I've come up with another "solution," which is deleting (or moving out) xulstore.json in the profile folder after exiting or before starting FF. You can create a batch command or script to execute the process.

So far, FF is connecting immediately after startup.

When I launch teams or slack from firefox on windows, I presume that a slack:// and teams:// or equivalent url is launched by the webpage.

As a developer working on Browser Picker, it would be quite handy if I could inspect these urls that gets launched, is there a way I can see the actual protocol url that got launched somewhere?

Firefox Version: 124.0.2 (64 bit) Windows Version: Windows 10 LTSC 2019 (Version 1809)

When I right click the taskbar and press close Firefox, here comes the interface just as the screenshot uploaded. The blue close button doesn't response no matter how I click it and the Firefox's taskbar is flashing yellow. This bug only occurs on the first window of Firefox and only when user right click the taskbar.

It has been a long time for me wishing that some updates would be released soon to fix this issue, while noting happens. Or this bug is only for me?

I just got a chromebook! Details:

Device name: Lenovo Flex 3 12.2" chromebook, 8GB ram. Intel N100 Device code name: IP Flex 3 CB 12 (pujjo, version 123.15786.0) Firefox version: 124.0.2 (flatpak) OS version: Version 123.0.6312.112 (Official Build) (64-bit) Chrome: Version 123.0.6312.112 (Official Build) (64-bit)

When I watch a youtube video with chrome my cpu usage is 20-30% When I do the same with firefox my cpu usage is 50%

Running `about:support` and going into `webrender_compositor` I get the following errors under `env`: 1. Blocklisted by gfxInfo 2. Blocklisted; failure code 3. FEATURE_FAILURE_WEBRENDER_COMPOSITOR_DISABLED

I have set almost all these force renders = True and even granted gpu access to firefox flathub but still no difference in performance. I am asking now because I am just going in circles in the rabbit hole.

I had used and uninstalled Chrome, and others. All I have is FF and ME. Some times when I attempt to open a web page, FF fails and I have to use ME. But other times ME fails and I need to use FF. I recognize that all browsers other than FF are the same or similar basis. So, how can I stick with JUST FF. And not have to keep ME updated or active. Just let ME sit there unused. Why can't FF work with all web sites? Is the problem with them or with FF?

https://register.ridgidpower.com/# is not working. Specifically the Sign-In link. It works just fine with MS Edge. I had all extensions off, anti-virus off and I also cleared the cache twice, and also followed the Help/Troubleshoot Mode to no avail. I'm using V125.0.1 64bit

I have uninstalled and reinstalled firefox and restarted my computer but it still will not load. When i first reinstall it it comes up but will not connect to the intenet.

Hey, i recently came across this post

https://support.mozilla.org/en-US/questions/1434510#:~:text=I%20view%20a%20lot%20of,viewer%20to%20black%2Fdark%20gray.

and i couldn't figure out how to do it. if anyone can tell me steps on how to do it i'll be glad.

thanks.

For some time now, Firefox has been unable to display quotes on Yahoo Finance; for example:

https://finance.yahoo.com/quote/MSFT/

The space where the price history graph for MSFT should be is blank except for a message saying "Loading chart for MSFT". The chart never loads. Sometimes Firefox issues a message saying that the site is "slowing down Firefox".

This happens for *any* quote, no matter what the ticker symbol.

I have tried running Firefox with a new profile, running in a private window, and running in Troubleshooting mode; the behavior remains the same. Clearing cookies and changing the tracking protection setting has no effect.

Oddly enough, when I attempted to report this page as not working, I couldn't submit my report (the Send button did nothing -- though this feature works for other sites).

Have others here experienced the same problem; and if so, is there a known cause/resolution?

Thanks in advance for any help.

My Windows 10 PC stopped working a few days & is disconnected & partially disassembled. I’m temporarily using an old Windows 7 PC which I brought up from the basement the following day. They both have Firefox on them.

I saved one bookmark on the Win7 PC today. It was there when I looked earlier. Now I went to use it again & it’s not there. But my Win10 bookmarks are there!!

How could that be?

I've received my new PC and will be migrating from my old PC (Windows 10) to the new PC with Windows 11.

I use local folders in Thunderbird to keep various projects separate and more easy to manage. I have copied the current Thunderbird profile on to an external hard disk, I have found the location of the local folders and they reflect the structure in the Thunderbird screen I see. Thunderbird has been unstable for a few weeks so I would prefer a clean install but don't want to lose a lot of content that I still need.

1. Is there a way to copy over just the local folders, eg export them, rather than the whole profile? I deliberately haven't cleaned the server recently so that I can get back emails that still are in the in_tray but once they are in local folders they disappear from the Yahoo server. 2. Is there anything else significant I should be aware of before migrating? There is a backup on Mozilla but I prefer a clean install.

Thanks in advance,

Anne

Even after numerous Uninstalls and a Reinstalls I keep getting this error notice when trying to open Firefox...

The application was unable to start correctly (0xc0000022)

When I run firefox on WSL2, buttons dont work on any pop up windows. Foe example when installing a firefox extention - it will download and pop up a small window at the top right to add the extentionto firefox. The buttons dont work. Another example is when opening up the firefox menu bar (hamburger bar) - it will pup up a small window to allow to open up settings, go to add ons, open bookmarks or history. The buttons dont work. Last example is the pop up window for this Ash your question page for firefox support - When clicking "Which topic best described your question - it will pop up a small window to select what type of question Im gonna ask. The buttons dont work.

I dont know how to fix this. I restarted, deleted my firefox profile, started of safe mode, nothing worked. How do I solve this issue?
