Hi all,

I've been having problems with firefox lagging constantly. General browsing around feels laggy - and opening new tabs pretty much causes my computer to freeze for a few seconds. During this time firefox causes the CPU to spike to 100% usage.

I've been using firefox for years on this computer with no issues. Hardware is pretty good (i7 5820k, 64GB of ram and an SSD).

So far I have tried:

  • Running in safe mode
  • Using a different profile
  • Downgrading to an older firefox
  • Changing allowed CPU cores from 8, to 4
  • Updated graphic card drivers to latest version

None of these work, and I'm getting a bit tired of the constant slow downs. Chrome works flawlessly, as does all my other software...

Any ideas?

Thanks!

I use firefox on Mac OS 10.14.6. Every time I quit firefox (Stopping the program, not simply closing all windows) everything is reset to defaults. For all intents and purposes, it's as though I deleted and re-installed firefox every time I quit out of it. Bookmarks are removed, and any default bookmarks I removed are re-instated. It also opens up the set-up and privacy web pages that it does for the first time when you open it. None of the preference files are locked, it's set to remember history and I'm not permanently in private browsing, it's not even supposed to delete cookies. It's been like this since the moment I installed it; refreshing firefox changes nothing, uninstalling and reinstalling it also changes nothing. The only thing that stays the same is that my computer keeps firefox as my default browser.

I had Bing as my homepage and search engine, and that has always worked fine, for many years. But after a recent Firefox update, the browser will no longer allow Bing as my homepage and search engine, and because I had set the browser exclusively for Bing, I can't access another search engine. I liked the Bing homepage because it had a new photo every day, and most of those photos were downloadable to use as wallpapers. Looks like I may go back to Internet Explorer [I don't like Edge]. Why won't Firefox allow Bing now? - it's not a security risk.

Need help configuring Firefox exceptions for Cookies and Other site Data so sites like the NY Times can remember me so I don't have to log-in to them multiple times per day.

I've even deleted Firefox and started over, but that did not resolve the issue.

I need an expert in this to help me as I'm just not getting it...though I have tried many different configurations of FireFox's settings.

Thanks

Hi, I created a new profile because of crashes. I have Firefox version 81.0.1 (64-bit). I have Ramdisk but I cannot edit anymore the cache location in browser.cache.disk.parent_directory. I can only toggle true-false but can't add the ramdisk location. Aren't we allowed anymore to use a ramdisk for cache?

Honestly, I have no idea how to describe it. I loved how when I played a video on Firefox, it wouldn't pop up with that annoying video title whenever I changed my volume. Now, when I'm watching a video or playing audio, this happens. And, it doesn't even get it right most of the time! Like for example, it does this instead! That's not even the page I'm on!

Is there any way for me to get rid of this? Thanks

I went to "Show All Bookmarks" and searched for a bookmark. I want to know what folder I put the bookmark in. I can't figure out how to do so.

Someone answered this question before:

https://support.mozilla.org/en-US/questions/1274811

"You can open this bookmark in a tab, possible in "Work Offline mode". If you click the highlighted star on the location bar then you can check via the Folder line where in the folder tree this bookmark is located (second down arrow and use the scroll bar)."

How do I get into "Work Offline mode"? Also, why is this so difficult?

Hello, I just restarted my PC after a Windows 10 update (Windows Update). Launching Firefox from the task bar no longer worked (link removed). So I launched Firefox from the start menu. A completely blank version of Firefox appeared on the screen, as if I had just installed it. No more favorites, no more extensions, no more customization. All Firefox installation files in the AppData directory are dated today. How can a Windows update remove a Firefox installation? Is it possible to recover favorites and bookmarks? Thank you for your answers. Regards,

Recently Firefox asked me to close so it could restart and install an update, and when it came back, it wasn't properly displaying a number of character sets for which I have the proper fonts installed. Sorry for the vagueness as to when this was, but I'm not sure. The attached table of letters from Wikipedia's article on the Phoenician alphabet gives a great illustration of the problem I'm having. All of these characters used to display.

The fonts work fine outside of Firefox. But the problem isn't limited to Wikipedia, as shown in the next screenshot from Tatoeba. And there are other, non-Semitic letters that I've also suddenly started having problems with - I think they're all the kind that a typical Unicode font might not support, leading me to wonder if Firefox is properly looking for another font, and it doesn't seem so, but I've had difficulty trying to fix this in settings and haven't found any threads here or elsewhere about how I might do so.

Right now, I'm logged in my Firefox account and have everything backed up (logins and passwords, bookmarks, history, etc). Thing is, I do not remember my Firefox account password, but thankfully I am logged in and synced through 3 devices. I think, there may be a situation when some time in the future, I will be logged out one way or another.

Is there a way to see my Firefox account password, since changing password results in everything being deleted? I want to not get involved in such a hassle of exporting and importing data, if I can help it.

Thanks in advance.

Firefox has been acting funny under Windows 10 lately so, I recently saved my bookmarks and logins to files (in anticipation that I may have to uninstall and reinstall firefox.) I read the article that explains that if "import from file" does not appear on the "logins & passwords" "more" menu (three dots) then, it means I have to go to about:config in the address bar and turn the feature back on. I went to about:config only to discover that I do not know the name of the preference that I want to toggle.

Does anyone know the name of that preference?

I just changed my browser because the version I had before wasn't compatible with a site I needed to use for school. On this version instead of using the cursor designs that are used everywhere else, it uses it's own versions and I can't find a way to change this. When I go to click on a link it turns into this really ugly version of the hand cursor instead of the normal one. I know this doesn't seem important but it's actually triggering panic attacks for me. Please help! I'm using linux mint.

Version 81.0.1 (64-bit) does not remember cookies. I logged in to my email, Facebook, LinkedIn and other sites and chose to remember the browser. When I restart the browser, I have to login again. This happens on all sites with passwords. I tried the sites and restarting Firefox several times with the same results.

I have disabled all tracker blocking, allowing everything through. Enhanced tracking protection is off for the sites. Cookies, etc. are NOT set to delete upon exit. This is new behavior. Earlier versions did not have this problem. Any idea of how to fix this?

Firefox used to revert to default printer settings every time we make an attempt to print. This was ideal for us since we are a business that prints the same style of documents frequently throughout the day, only requiring us to change the settings as needed for one-offs that had different requirements. It was very efficient.

Since the latest update, Firefox "remembers" any changes in printer settings for the next time it prints. So, when we make changes for those one-offs, the next batch of prints are coming out wrong. It is wasting a lot of paper and time.

Is there an option somewhere in Firefox's about:config that turns off Firefox's print settings memory, and forces it to revert to the default printer settings?

I'd like to hide the title bar in Firefox. It takes up valuable on-screen real-estate, and doesn't really serve a purpose (other than showing a web page's full title, which I'm not interested in anyway).

In this screenshot, I have Firefox on the left, and Brave on the right. Now, I know it's only about 30 or so vertical pixels, but the title bar in Firefox is taking up a lot of space that could be used for actual web content.

Is there any way to disable this top bar? Or is it baked into the actual program itself?
