Firefox bowser stopped working suddenly. Tried uninstall and install multiple times with multiple options.

Still not working even after cleaned all Firefox related files using uninstall tools and installed again.

ver 111.0 does not start, shows 3 entries in Win task manager, 3rd entry shows not responding. Sometimes will start after "end task", then shows 9 entries and browser window shows "start new session". Most times doesn't start. Have tried most of the web fixes no help. Been using firefox for years. Believe this started with recent update which I have set to auto. Thanks, Mike

Just wondering why I can't access www.newsmax.com with Firefox. I have no problem with other browsers.

This is the message I get: Network Protocol Error

An error occurred during a connection to www.newsmax.com.

The page you are trying to view cannot be shown because an error in the network protocol was detected.

   Please contact the website owners to inform them of this problem.

Hi. I am having 2 issues with 111 on a Win 10 Pro 64 machine. Issues are new following update to 111.

(1) "Save As" is not working for images or pages. Right click will open the menu but selecting save as doesn't do anything, nothing happens. CTL-S also does not do anything. Have tried clearing download history, download folder, selecting new folder.

(2) Cannot select Privacy & Security tab in Settings. Clicking P&S brings back General. See screencap.

Also, the image for Firefox is up to date is missing. See screencap.

I've recently updated to version 110.0, and I immediately noticed an issue with my bookmarks where my scroll position in the bookmarks list isn't being saved after opening a tab or two. It keeps resetting back to the top of the list after a few seconds.

I don't know if this is a bug resulting from the latest update or what, but I know I didn't have this issue with bookmarks prior to updating to 110.0.

Hello,

Today Firefox gave me an updated it crashed somehow, and it kept crashing and crashing I unstaled it but now I can't install it anymore same goes for Firefox Nightly

Mozilla lags a lot when it's started, it takes ten thousand hours to open a tab when it's started. YouTube lags a lot and specially when 60fps videos are watched and shorts are being watched. Otherwise everything works well with other browsers, but Mozilla.

Since my Firebox browser automatically updated on Feb 20, 2023, it crashes several times a day. Is this a known issue? Will there be another update released soon to fix this issue? Or how can I fix this on my end? Thank you.

PR_END_OF_FILE_ERROR only happens after power outages, and occasionally after internet outages, and can't be resolved unless I have cable company send reset signal to my modem. I have tried every trick and trouble shooting recommendation I have found here and elsewhere on the internet and nothing else works.

Used to be I could clear my cache/cookies etc, do a PC restart, repeat that 2-3 times and the issue would resolve it's self but not in the last 6-12 months. My cable/internet company is baffled by this and can't explain it since it is a Firefox issue but it still takes me 30 mins every time to get them to just send the stupid reset signal because I know what I'm talking about. I wanted to send this to you in case there are others that also experience this and have a fix or are as frustrated as I am. We lose power often in the Midwest with storms.

Yesterday I left work and my computer on with several Firefox tabs open. Today I came in and Firefox was closed. Double clicking the icon on my desktop, or on the icon in the taskbar gives the small circle loading symbol next to the mouse for about a second. But no browser window opens. There is no indication in the Task Manager that a Firefox browser is open.

I have attempted to restart my computer several times. I have uninstalled and reinstalled Firefox. I have tried updating Firefox. I have checked that all my drivers on the computer are up to date. I have run a Malwarebytes virus scan on my computer. I cannot get Firefox to open to check any other settings. I have tried to open Firefox on another account on the same computer and it also results in the same thing.

If anyone has any ideas that might fix this, I would really appreciate it. Thank you. Computer is a Dell OptiPlex 5070 running Windows 10.

Since updating to 111.0 my Firefox browser crashes. I can open it up, and select a site, but when I select things within the site it crashes. I tried uninstalling and reinstalling it but still the same issue. This problem never happend before the 111.0 update. This is on a MacBook Pro w/Monterey OS, M1 chip.

Hello. I cannot watch videos from invidious.snopyta.org on my laptop with Firefox 52.9.0, because a message that says "No compatible source was found for this media." appears in place of the video player. However, the videos from that website do load correctly on my other PC with the latest Firefox version, and they load correctly on this laptop as well when using Google Chrome. The video found on this site, which I think is a webm, plays correctly.

What video format does invidious.snopyta serve and why can't it be played by Firefox?

After the update to 111.0 Firefox crashes. I can open it up, go to a site etc. but eventually it crashes. I deleted it and reinstalled, same problem. This has never occured prior to 111.0.

Firefox has been randomly crashing for me for months now, which minimizes everything I had up, usually at a bad time. Firefox doesn't even have to be running for it to crash and interrupt what I'm doing.

Most recent crash report: bp-495b94c7-0b6a-46d1-8570-75b970230315

I have v110.0.1 (64-bit) on my PC. I had originally thought there was a memory leak because memory usage kept growing. But that doesn't seem to be the case. Instead the memory usage seems to be very high in this version. It seems to have stopped at between 1400 and 1500 MB's, which is about double of previous versions.
