Firefox Community Forum

I am using Kubuntu 25.04. I tried support but the support in Firefox doesn't seem to have much help for OSes beyond Windows even though they make a native Linux version. I subscribe to several extensions and use Firefox sync to get the extensions onto a new computer but they don't automatically pin to the menu bar. I figured out how to do that once but I forgot how I did that and can't find it in help. Can someone please tell me how to do that. Mozilla, if you are reading this you might want to improve the support in your Linux version.

The last time Firefox updated I lost all my bookmarks. Tried using the restore tool and it didn't work. Tried restoring from my USB drive, didn't work either. Can you PLEASE help??

after the recent update I could no longer 'like' articles or comments on substack, and I couldn't post comments, either. looks as though there was a fix the next day, because I was again able to 'like' and comment...but then late that night I was suddenly back to square one. exactly the same issue. it's now been a couple of days and I still can't 'like' or comment on substack.

this same thing happened after an update many months ago, and after a week or two I just switched to opera. checked firefox again in september or october and it was working so I stayed. I'd like to keep using firefox but the substack problem is annoying. why did it work for about eight hours and then stop again? it seems as though substack is the poor step-child. hope you can get this fixed! because having to change browsers is also annoying...

thanks!

My computer (pc-windows 10) keeps freezing. Today, when this happened I launched Task Manager and discovered Firefox had opened 68 instances (I had one window open) and was using up 100% of my Core i7 CPU. I was on YouTube at the time.

I'd like to stay with Firefox as I have been using it for years, but this is happening all too often. Is there a way to limit the number of instances that it will generate?

I have been using Firefox as my default browser for years on all my computers. I have a computer at work and one at home. My home laptop has for some time now been telling me that AI search results are "not available right now, try again later". Initially I thought this was transient, however it has not changed. I have tried to find a setting either in firefox or google that has changed but I cannot. My other laptop works just fine with AI searches on google. Please help my email is [edited email from community support forum] (I do not use my google email.)

I had to get a replacement keyboard,and it worked for a while , And then about a week ago, no volume on you tube,google ,but i have audio on mirosoft edge. Checked volume setting's over several times. An advisor told me ,that the logitech keyboard maker,installed optional driver's , that could have caused this? I searched device manager ,to uninstall but didn't find it?

Whenever I install a new system with a GUI — which is quite often as the responsible for the network — it's unavoidable to have Firefox on it since is hit and miss with uBO and the Chromium ones.

Except for the pages that load automatically on install, before I open the first page, and before I enable sync; I make sure to match my settings on other Firefox instances first. I even set several in about:config too; namely anything related to QUIC/HTTP3, encrypted DNS, and this relentless need Firefox has to navigate automatically to the HTTPS version of a domain as if they were always the same site. Technically speaking, they're not even the same server but I digress, when I finally enable sync it reverts all* the settings to defaults again.

I thought this was synced down from somewhere but recently I installed Firefox on an older system, I did the ritual with the settings, the candles, the about:config, the dead cat, y'know… the whole thing, and enabled sync. But what it actually happened was; I only logged in. Sync remained off. It read something like "sync off" in the setting next to the big blue button to turn it on.

Before I click the button, I opened a new window, and went to the settings again to make sure that the settings on the current window weren't stale. I noticed the reversal had already happened. Despite nothing had been synced I already was back to defaults.

I changed them back.

When I clicked on the button, the usual selection of things I sync was already done, I just had to confirm it and that was all. Once it finished, my settings were change to defaults… again! Albeit to a much lesser degree. The password manager turned itself on again, but not all the checkboxes below the main setting, one of the two Recommend, something-something while I browse was turned back on, I think Show search suggestions in address bar results was turned on too, and I don't remember if the settings for Firefox Home were changed, they often are, I don't use it at all, but it's rather easy to accidentally have the shortcuts from that page to prepopulate in the address bar drop down.

There must be one setting that prevents this, on Windows I think I have it under control (Firefox is preinstalled and preconfigured through Active Directory), that would be awesome if anybody actually used Windows, we only have it because our accounts are in Active Directory, but it does prove that it can be controlled. Most of the settings that have disappeared from Firefox are still available to Enterprise administrators and then some …which is a bit telling from the browser that allegedly champions privacy.

I want Firefox to let me navigate to "dangerous sites", so I learn early from my mistakes, not later when these protections have made me careless and it's riskier; to keep remembering on my own to keep my passwords fresh, not have that software crutch that relies on a third party service; to be a browser, not my operative system.

Although I'm not a dev, you can get as technical as you want, no need to dumb it down; if I don't understand it, I will be happy do my homework, just tell me how, please (and thanks.)

• not all but it feel like it: it's mostly those that use Mozilla's hosted services, I believe, such as the password manager and the like.

I was using the Firefox browser on Windows 11 desktop to make a donation. When prompted for my name and address I had Firefox autocomplete the fields on the form. When I went to click donate I noticed that Firefox autocomplete had changed my donation amount to my phone number which resulted in a 5 billion dollar donation amount. Can you tell me how this happened?

My fire fox which I have used for years is loading page very slowly and then freezes some times but just tried my Edge Browser and its as fast as my fire fox years ago. what can I do to speed it up
