I-Firefox Community Forum

For some weeks I have ad an issue with Firefox using 50%-100% of CPU. Normally it is the Firefox process itself, sometimes it is also "Privileged Cont".

OS is Kubuntu 24.04. Firefox has done this across 2-3 versions.

Things I have tried:

Restarting Firefox No change, I'll even get 100% cpu usage with no tabs open

Refresh Firefox to remove settings and addons No change

Uninstall Snap and try direct Apt package No change

Remove ~/.mozilla to fully remove any residual settings/cache/etc No change

Try with and without hardware acceleration See: https://support.mozilla.org/en-US/questions/1308215 No change!

I would blame my old computer hardware, but Brave runs fine. I am now using Brave, but would dearly like to return to Firefox as I miss containers, and I don't support a chromium dominated web.

How can I get FireFox to open a webpage on a website on my LAN.

Chrome has same problem.

Safari gets to the webpage fine.

Hello! I started encountering this problem as I updated my OS to windows 11. I had eset nod antivirus, but uninstalling it nothing changed. Tried to change MTU cache size through CMD. Changed different DNSes Tried to disable all protection settings in browser and in windows settings. Deleted all extensions. NOTHING helped except clearing cache of the browser, but this is fixing problem only before first browser restart. Other browser on laptop works normally without any issues.

I'm having problems connecting to a server. I know it is a valid address because I can get it on other computers but it is now block on my computer. Is this a firewall problem and if so how do I fix it. the server address is" click.coverkit-mail2.com". How do I fix this?

I don't understand why a page is not opening in normal windows, but it opens in private windows. I have tried to clear the cache, but I still have the same problem. Not all URLs have this issue; just some of them.

I have Firefox version 136.0.2. I think it was quite recently updated. The right click menu is broken. The choice list is much longer, and the choices "open link in new tab" and "copy link" (ones I tried) do not work. This only started happening this morning. Right click works fine in Chrome. Screenshot included.

I use the French Search Engine, Quant in place of google. It works well, normally. I have just found the following message;

"We detected unusual activity from your device or network.

Reasons may include:

   Rapid taps or clicks
   JavaScript disabled or not working
   Automated (bot) activity on your network (IP 96.241.216.175)
   Use of developer or inspection tools"

I don't know why this has occurred. No one else uses my laptop. How do I get rid of this message and access Quant?

Attachment is a screenshot shows task manger shows there are 64 open files open, when I have only 4 windows open. What would causing this?

Over night Firefox closes and close all my open windows. I need the windows remain open.

Thank you for sharing your wisdom with me.

At some point in the last few weeks -- possibly after an upgrade -- I've noticed that some websites such as the Washington Post and Fidelity can take minutes rather than seconds to load. The problem doesn't seem to be with the sites themselves (because they load fine on Chrome) or with my hardware (because exactly the same thing happens on both of my computers). Has anyone else noticed this?

( I'm running Firefox 131.0.3 on Windows.)

A couple of years back there was an extension called Tab Mix that allowed users to have multiple rows of tabs to allow more to be visible at a time. A major revision to Firefox rendered it useless. Another user figured out how to allow multiple rows of tabs (https://www.youtube.com/watch?v=oVlLVySe5OI) which worked perfectly until version 131.0-64bit came out. Whatever was changed in it made the hack quit working. I really liked being able to see multiple rows of tabs because I tend to keep a lot open. I'm hoping that can be fixed with the next revision or two or that one of you has a different work-around.

This is a recent thing in the last few weeks, My aux speakers (via headphone jack) work normally with all audio output except when using firefox. The sound on any video I play via firefox gets sent to my laptop speakers, not to the aux spearkers. Changing the laptop audio output settings does nothing. The sound is output properly with other browsers. Any suggestions on how to fix this problem?
