Firefox will only start if I sign in as an administrator. It doesn't connect to the internet, and I can't get to the help screen. I did a refresh but that hasn't help. If I uninstall and then reinstall a new copy correct the problem? How do I save and reinstall my bookmarks and settings? I love Firefox and prefer it over other browsers. But I need to fix it and any help you provide will be very much appreciated. Thank you!

For the last 2-3 day I have been experiencing a box that asks for my signature each time I go to a new website. I can't move the box. I can't screenshot it. Does anyone know how I can get rid of it?

In Firefox's Task Manager, how do I know which tab is using which subframe(s) process?

For example, let's say I open Firefox and with only one single tab open, I open the following web page: https://audioplugin.deals/product/best-of-zampler-collection/

That page apparently includes content from several third-party websites because when I open it, Firefox's Task Manger shows processes for the following:

https://audioplugin.deals https://cloudflare.com https://google.com https://hcaptcha.com https://soundcloud.com https://stripe.com https://stripe.network https://stripecdn.com

The process for "https://audioplugin.deals" is the only process with a tab. All of the other processes are subframe(s) only, with no mention of which tab is using them.

With only one tab open, I intuitively know that all of these processes must be used by that one tab. But like most people, I browse using multiple tabs, and once you open multiple tabs, it becomes (as far as I can tell) impossible to determine which subframe(s) process is used by which tab. This makes it impossible to determine which tab is behaving improperly or erratically when there are issues (for example, when one of those subframe(s) processes is consuming an unreasonably large amount of memory or CPU cycles).

The recent update changed how the mute button works in Firefox, before it would replace the icon and would show text and whatnot if it was muted or wanted to autoplay; now it just always shows the mute/unmute button in a tab playing audio. This would normally be fine but it is causing my tabs to constantly be shrinking and expanding whenever the audio changes in a tab, and it's really frustrating me and it feels like an overall far worse user interface design than it was before, even if people were complaining about it. Is there some sort of middle ground where I can set a maximum tab size or something? I know this used to be a feature in about:config but it doesn't exist anymore for some reason. I've also tried using a userChrome CSS code for it that I found online; it got rid of the button but it still made the tab size change and the code I tried using for maximum tab size also didn't affect that. Really starting to frustrate me! Please give me any advice I feel like I've exhausted all my options lol

Hi everyone,

I’m running into a frustrating issue where Firefox is opening PDFs in two places at once.

The Problem: When I click a PDF link, Firefox opens the file in a new tab (internal viewer) but also launches the standalone Adobe Acrobat app to display the same file. I only want it to open in Firefox.

Details: - Settings: My "Applications" setting for PDF is currently set to "Always Ask." - The Glitch: Even when I manually select "Open in Firefox" from the prompt, Adobe Acrobat launches anyway. - Timeline: This started happening 2 days ago without any manual setting changes (I think it might be after a firefox update? I might be mistaken)

- Troubleshooting done: I have tried toggling the action to "Open in Firefox" directly, but the dual-launch behavior persists.

Thanks

Links keep opening in new windows, and not within new or same tab. Shift key is not stuck and all toggles in the Tabs Opening/Interaction Settings field have been turned off

Recently, whenever I put a video in PiP, the whole browser freezes. I'm not sure what causes it. The PiP player itself is playing and working fine, it's the browser as a whole that freezes completely. I can play/pause and even pop it back to its tab, but when I do, the browser is inaccessible to me because it freezes, despite the video still playing normally. I can only terminate the browser with Task Manager, otherwise the video will continue playing and the Firefox process goes on the background.

I have tried Googling for a way to fix it, but nothing seems to work. Some of the recommendations were to turn Hardware Acceleration off, allow autoplay, upgrade GPU drivers, and test in Troubleshoot Mode. I have autoplay completely off (including in about:config) and gave an exception to YouTube. I don't think this is the problem though, because I've had it set up this way for a long time, and the browser freezing only started happening recently. I have had Hardware Acceleration off for a while too, so it's not because of that. My GPU drivers are up-to-date (Nvidia). The browser still freezes in Troubleshoot Mode.

The problem is not limited to YouTube. Wherever I can pop the player off with PiP, it will freeze the whole browser (like Twitch or any other site with video player capabilities). I tried playing a video in a different browser and it worked just fine with no freezing, it only happens in Firefox.

I noticed that the common issue people report is the PiP player itself freezing, but my case is the exact opposite. The PiP plays fine while the rest of the browser freezes. I really like this feature and don't want to turn it off if possible. I like to pop the video out and watch it play while I scroll around on my desktop.

Hello. I have a question about Firefox. I shut down my PC and turned it on two hours later, but Firefox is still displaying page layouts properly, images on pages aren't displaying, and the screen remains blank even when I load a page from a bookmark. How can I fix this? This is the first time I've seen this happen, whether I've restarted or shut down and restarted.

I like to use picture-in-picture mode to watch a YouTube video in the corner of my screen while editing an image or playing an online game (since I like having something to keep my brain active while I'm doing something). Recently, however, this has resulted in my computer locking up. I don't really know how to describe it succinctly, but audio becomes super stuttery and it takes a second or more to render a single frame. Last night this resulted in the loss of an in-progress image (don't worry, I took photos of my screen so I could recreate the image), so I want to figure out how to stop this.

Just to cover my bases, here's my specs:

Couple of updates back, Firefox quit working as before on a particular webpage. See attached images. Describing the webpage, this is from an embedded server on a Burk Arc Solo radio transmitter monitoring and control system. Accessing the webpage allows control over the transmitters in addition to getting readings on the performance of the units. The Edge browser shows how it's supposed to look, meter names and data values, they self refresh and show changes dynamically. Why is the Firefox no longer doing this? Note: this is at a remote site using remote desktop to access the machine watching the Burk. The machine is Windows 11.

How do I completely uninstalled Firefox and revert back to the previous version, and turn off auto updates?

Could someone please help me retrieve my crash report history? My Firefox crashes more than 10 times a day. When I check **about:crashes**, it doesn’t show any reports right now, although I saw some there a few days ago. Is there any way to recover those reports so I can submit them here for further guidance from experts?
